A shutter plate 14 that allows the opening 12 to pass through when the shutter plate is opened; the powder or granular material supply unit 13 is provided in the opening 12 as a hindrance plate 15 arranged in the opening 12 in a direction D2 that intersects the moving direction D1 of the shutter plate 14. Has.

With this configuration, since the baffle plate is arranged in the direction intersecting the moving direction of the shutter plate, the powder or granular material falling through the opening can be uniformly dispersed and sprayed.

Further, in the powder or granular material dispersion and supply device 10 according to the second aspect of the present invention, in the powder or granular material dispersion and supply device of the first aspect, the obstruction plate 15 is attached to the end portion 151 on the inflow side of the powder or granular material 11. It may be a structure with an inclination 152.

Further, the powder / granular material dispersion / supply device 10 according to the third aspect of the present invention has one or more obstruction plates 15 in the powder / granular material dispersion / supply device according to the first aspect or the second aspect, and is described above. The distance at which the openings are separated by the baffle plate is 50 mm or less.

If the distance at which the openings are separated by the baffle plate is made larger than 50 mm, the dispersion effect is reduced.

Further, the powder / granular material dispersion / supply device 10 according to the fourth aspect of the present invention controls the opening / closing of the shutter plate 14 in the powder / granular material dispersion / supply device of any one of the first to the third aspects. A control device 21 is provided.

With this configuration, the powder / granular material supply unit is a flat plate-shaped powder / granular material supply plate, so that the shutter plate can be configured to move in parallel with the powder / granular material supply plate. Also, the structure is simple. As described above, since complicated equipment is not used, dirt due to loss of powder or granules or clogging is unlikely to occur, and maintenance such as cleaning is easy.

In order to achieve the above object, the method for producing a powder or granular material dispersion according to a sixth aspect of the present invention is, for example, as shown in FIG. 4, the powder of any one of the first to fifth aspects.

It is a top view which shows the difference of the dispersion state of the powder or granular material by the shutter speed. (A31) indicates a case where the shutter speed is slow, and (A32) indicates a case where the shutter speed is high. It is a flowchart which shows the manufacturing method of the powder or granular material dispersion.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, members that are the same as or correspond to each other are designated by the same or similar reference numerals, and duplicated description will be omitted.

First, the dispersion supply device 1 for cookie powder (powder / granular material) as the powder / granular material dispersion supply device 10 according to the embodiment of the present invention will be described with reference to the perspective view of FIG. This device is a device that evenly sprays crushed and granulated cookie powder onto ice cream.

In this device, a powder or granular material supply plate (spacer) is horizontally provided as a powder or granular material supply unit 13 in which an opening 12 through which the cookie powder as the powder or granular material 11 passes is formed. Below the powder or granular material supply plate, a shutter plate 14 provided so as to move along the lower surface thereof is provided. The shutter plate 14 is configured to open and close the opening 12 by moving across the opening 12. A predetermined amount of powder or granular material 11 is supplied onto the shutter plate 14 when the opening 12 is closed. The powder or granular material 11 is used as an object 17 for dispersing the powder or granular material 11 placed under the opening 12 by passing through the opening 12 when the shutter plate 14 moves and the opening 12 is opened. Sprinkle on a cup filled with ice cream. That is, it is sprayed on the surface of ice cream. The powder or granular material 11 passes through the opening 12 due to gravity. Here, the predetermined amount is an appropriate amount required by the product to be sprayed on the upper surface of the product. Typically, it varies from product to product. This can be determined in advance by experimentally making a product such as ice cream which is a specific object 17. The powder / granular material supply plate 13 has a flat plate shape, and the shutter plate 14 can be configured to move in parallel with the powder / granular material supply plate 13 without rattling.
The phrase "moving across the opening 12" of the shutter plate 14 includes not only the case where the shutter plate crosses by a linear motion as shown in FIG. 1 but also the case where the shutter plate crosses by a rotary motion. For example, there is a case where the vicinity of the peripheral edge of the disk-shaped shutter plate is pivotally attached to the vicinity of the opening of the powder or granular material supply plate to rotate the vicinity of the peripheral portion to open and close the opening.
In this case, the disk-shaped shutter plate is divided into two along the diameter line and pivotally attached to the vicinity of the opening of the powder or granular material supply plate at one end of the diameter. Then, the disc divided into two may be rotated in opposite directions (like scissors) to open and close the opening.

The opening 12 is formed in a circular shape, and an obstruction plate 15 facing the direction D2 intersecting the movement direction D1 of the shutter plate 14 is arranged. The angle of intersection is 90 degrees in the present embodiment (here, the angle perpendicular to the shutter moving direction D1 (direction of D2) is 0 degrees). The diameter of the opening 12 depends on the size of the object 17 to be dispersed, but in the case of ice cream, it is typically 60 to 90 mm, for example 76.8 mm. As shown in FIG. 1 (C1), the baffle plate 15 is formed in a rod shape having a cross-sectional width W and a height H of 5 mm.
When the width W and the height H of the cross section are 5 mm, it has a vertical plane of at least about 2.5 mm in the vertical direction. The width W and the height H depend on the size of the particles of the powder or granular material and the size of the opening 12. When the powder or granular material is a product passing through a 4 mm mesh, the width W and the height H are preferably 2.5 to 6 mm. The width W and the height H should be appropriately adjusted according to the size of the powder or granular material within a range in which the strength can be maintained. The larger the granules, the higher the height H. This is to prevent large grains from getting over the obstacle board. Further, it is preferable that the width W is reduced as the particles of the powder or granular material are smaller or the smaller particles are mixed. This is to prevent the powder or granular material from accumulating on the obstacle plate.
Further, the height H may be larger than the width W. The obstruction plate 15 is referred to as a "plate", but when the height H is the same as the width W, it may be more appropriate to call it a "bar", but in the present specification, it is also referred to as an obstruction plate. The corners may be chamfered as appropriate. Although it is an obstacle board, it can be regarded as a stick, so when referring to a number, it may be called, for example, two or two.

The distance (width) at which the opening 12 is separated by the baffle plate 15 is preferably 50 mm or less, more preferably 5 to 45 mm, still more preferably 10 to 40 mm. If the distance (width) at which the opening 12 is separated by the baffle plate 15 is too narrow, it may adversely affect the dispersed state. Since it is difficult for small powder particles to move beyond the obstruction plate 15, the dispersed state is affected by the position when the powder is dropped from the shooter onto the shutter. If the distance (width) at which the opening 12 is separated by the baffle plate 15 is too narrow, it may not be possible to supply the powder or granular material in a state of being uniformly dispersed on the surface of the object.
Here, the "distance in which the opening 12 is separated by the baffle plate 15" is the maximum distance between the baffle plate 15 and the inner circumference of the opening 12 (measured from the outermost baffle plate 15 to the inner circumference of the opening 12 in the vertical direction). The maximum value of the distance, that is, when the opening 12 is circular, is the distance between the tangent line drawn parallel to the baffle plate 15 and the outermost baffle plate), and when there are two or more baffle plates 15. Refers to the distance between adjacent obstacle plates 15.

As shown in FIGS. 1 (C2) and 1 (C3), the baffle plate 15 may have a structure in which an inclined 152 is attached to an end portion 151 on the inflow side of the powder or granular material 11. Typically, the baffle plate 15 is formed into a square or vertically long rectangle in cross section, and is inclined so as to chamfer both corners in the longitudinal direction (direction of D2) of the upper end surface (typically a horizontal plane) 151. Attach. When the inclination 152 is attached, the flow of the powder or granular material 11 becomes smooth, and the accumulation of the powder or granular material 11 at the end can be suppressed. The angle θ of the inclination 152 is set so as not to prevent the powder or granular material 11 from falling and to maintain the strength. It is preferably 30 to 80 degrees, more preferably 40 to 60 degrees, and most preferably 45 degrees with respect to the (horizontal) plane of the powder or granular material supply plate. The inclination 152 may be a flat surface or a curved surface. In the case of a curved surface, the tilt angle is viewed, for example, at the angle of the central portion of the sloped portion (the portion between the top of the end 151 and the side surface of the baffle plate).

Even when the slope is provided, as shown in FIG. 1 (C2), a flat surface portion may remain on the upper side to the extent that the accumulated powder or granular material 11 does not matter. When there is a flat surface portion, damage to the end portion (chip of the edge) can be suppressed as compared with the case where the end portion has an edge shape. The width of the flat surface portion may be 1/8 or less of the width W of the baffle plate 15. That is, when the width W of the baffle plate 15 is 2.5 to 6.5 mm, it is preferably 0.8 mm or less. Further, instead of leaving the flat surface portion, as shown in FIG. 1 (C3), the end portion 151 of the baffle plate 15 may be rounded. Typically, R (R) may be added. The flow of the powder or granular material becomes smoother, and not only the accumulation of the powder or granular material at the tip portion can be suppressed, but also the damage to the tip portion can be suppressed more effectively. When adding R (R), it is preferable that R = 0.8 mm or less in order to suppress the accumulation of powder or granular material. When rounding, the radius of curvature should be R = 0.8 mm or less.

The crossing angle of the hindrance plate 15 with the moving direction D1 of the shutter plate 14 is preferably 90 degrees (orthogonal) (direction of D2), but may be an angle in the range of 90 ± 10 degrees.
As a result of trying in the case of making an angle with respect to the direction D2 or in the case of a cross-shaped character, it was found that the case of only the direction parallel to D2 is the best. At an angle, dispersibility tended to be poor in all rows, regardless of the number of baffles. In particular, when the shooter 16 is inclined, the tendency becomes stronger as the angle formed by the shooter 16 and the powder or granular material supply portion 13 becomes smaller.

As for the material, it is preferable that the powder / granular material supply plate 13 is made of resin and the shutter plate 14 is made of stainless steel together with the shooter 16. Austenitic stainless steel is particularly preferable. This is because it has excellent stain resistance. When the powder or granular material supply plate is made of resin, it is possible to suppress the generation of foreign matter due to wear between the metals and the shutter plate 14 made of stainless steel. It also contributes to the smooth operation of the shutter plate 14. As the resin of the powder or granular material supply plate, ultra-high molecular weight polyethylene resin or Teflon (registered trademark) which is a fluororesin is preferable. This is because it has excellent wear resistance.
As shown in FIG. 1, the shutter plate 14 may be flat, bent at a right angle or the like so that the stop position is secure, or a protrusion may be provided on the shutter plate 14 as a stop portion.
The obstruction plate 15 is preferably integrated with the powder or granular material supply plate without a joint. With such a configuration, maintenance such as cleaning becomes easy.

In the present embodiment shown in FIG. 1, a plurality of openings 12 are formed in the powder or granular material supply plate 13. This is to make it suitable for mass production. Above each opening 12, a tubular shooter (pipe) 16 for supplying the powder or granular material 11 is arranged on the shutter plate 14. A weighing device (not shown) is provided on the upper portion of the shooter 16. The weighing device supplies a predetermined amount of powder or granular material 11 to the shooter 16. The powder or granular material drops the shooter 16 over a certain period of time and is uniformly dispersed on the closed shutter plate 14.

The powder or granular material 11 weighed by the weighing device falls through the shooter 16 and is temporarily held on the closed shutter plate 14. The weighing device includes a hopper for accommodating the powder or granular material, a measuring unit for weighing a predetermined volume or a predetermined weight of the powder or granular material contained in the hopper, and the powder or granular material to be weighed by the powder or granular material supply device of the present invention or the following. It is equipped with a shooter for sending to the stage of, and further, a transfer unit for transferring from the hopper to the measuring unit and a control unit for controlling the transfer, so that the accuracy of weighing can be improved. As the weighing method and measuring unit in the weighing device, known devices such as JP-A No. 60-66120, JP-A-2578684, JP-A-6-263103, and JP-A-2001-124619 can be used intermittently. The powder or granular material is weighed by providing a device for sending the driven and weighed powder or granular material to the next stage, or an opening / closing mechanism that opens and closes based on the weight measuring device and the signal from the weight measuring device.

In the configuration in which the powder or granular material 11 is directly supplied from the shooter 16 onto the object 17, it is necessary to wait for the shooter 16 to fall for a certain period of time, so that the productivity tends to be low. Therefore, once the device is mounted on the shutter plate, the object in which the powder or granular material 11 has been sprayed while the predetermined powder or granular material 11 is being supplied onto the shutter plate 14 with the shutter plate 14 closed. The object 17 can be replaced with the next object 17. In this way, productivity can be increased.

With reference to FIG. 2, the dispersibility test result by the distance between the baffle plates (when there are two or more baffle plates) or the distance between the baffle plates and the inner circumference of the opening will be described. The diameter of the opening was 76.8 mm. As the powder or granular material, cookie powder (powder or granular material) that was crushed and passed through a 4 mm mesh was used. The arrangement state of the baffle plate is shown on the left side. The distributed state is shown on the right side. The black part in the photo is the powder or granular material. The arrows in the figure indicate the direction of movement when the shutter plate is opened.

As shown in FIG. 2 (A21), in the powder / granular material supply plate having no obstruction plate in the opening, the powder / granular material that should be uniformly dispersed on the shutter plate is moved when the shutter is opened. , It will be biased to the moving side on the object.

FIG. 2 (A22) shows a case where one baffle plate is provided in the opening. The opening is a circle with a diameter of 76.8 mm, and the baffle plate is provided along the diameter of the circle. At this time, the distance from the obstruction plate 15 on the inner circumference of the obstruction plate 15 and the opening 12 to the farthest point in the perpendicular direction (maximum distance between the obstruction plate and the inner circumference of the opening) was set to 35.6 mm. The cookie powder, which is a granular material, could be dispersed almost uniformly on a paper cup as an object. (A23) is a case where two obstacle plates are provided. The distance between the two baffle plates was 19.5 mm, and the maximum distance between the baffle plates and the inner circumference of the opening was 24.7 mm. At this time, the uniformity was higher than that of one sheet. (A24) is a case where there are three obstacle plates. The distance between the three baffle plates was 13.3 mm, and the maximum distance between the baffle plates and the inner circumference of the opening was 19.4 mm. The case of two baffle plates is the best, but the uniformity is greatly improved in any of the cases of 1 to 3 as compared with the case of no baffle plate. It is estimated that the degree of improvement does not change much even if there are three or more. In terms of the maximum distance between the baffle plate and the inner circumference of the opening, or in terms of the distance between the baffle plates when having two or more baffle plates, the degree of improvement does not change much even if these are made smaller than the predetermined values. It is presumed.

FIG. 3 shows the difference in uniformity depending on the speed at which the shutter plate is opened. In this example, the crossing angle between the baffle plate and the moving direction D1 of the shutter plate is 90 degrees, the number is two, and the width W is 5 mm. (A31) is a case where the shutter speed (also referred to as a shutter moving speed or an operating speed) is slow, and (A32) is a case where it is faster than (A31). A paper cup was used as the object. A paper cup was placed for each of the slow and fast cases.

As a result of this test, it was found that the faster the shutter plate 14 is opened, the better. Further, when the length of the shutter moving direction D1 of the opening 12 is 100 mm, it is preferably 30 mm / sec or more, preferably 80 to 300 mm / sec. Further, when the shutter plate 14 moves in the opening direction, vibration may be applied to the shutter plate 14.

The control device 21 includes an opening / closing unit for opening and closing the shutter plate 14, and a timing storage unit for replacing the object 17 on which the powder or granular material 11 is sprayed with the object 17 on which the powder or granular material 11 is sprayed. In particular, the time for the powder or granular material 11 to reach the shutter plate 14 from the weighing device through the shooter 16 is important. This time varies depending on the material and particle size distribution of the powder or granular material 11, and it is preferable to specify a specific time by a prior trial. The method for producing a powder or granular material dispersion is carried out according to the stored timing. That is, an appropriate time interval is obtained from the time when the powder or granular material is released by the weighing device to the time when the powder or granular material is temporarily held on the shutter plate and then the shutter plate is opened. Save the time interval and open and close the shutter plate at an appropriate timing. For example, when the cookie powder is passed through a 4 mm mesh, the particle size of the powder is not uniform and contains particles having a smaller diameter. Small-diameter particles take longer to drop the shooter than large-diameter particles, so the timing of opening the shutter plate is determined according to the particle size of the powder or granular material in consideration of this after trial. The time interval from when the powder or granular material is released by the weighing device to when the shutter plate is opened may be determined by the time required for replacing the object.

A test was conducted using a cookie crushed product on an actual machine.
The diameter of the opening was 76.8 mm as described above.
The test raw material is a cookie crushed product, which is a powder or granular material passed through a 4 mm mesh. The particle size distribution of the cookie powder (powder and granular material) that passed through the 4 mm mesh was about 40% with a small particle size that passed through the 1 mm mesh.
The number of baffle plates 15 was 1, 2, 3, and the widths W were 3 mm and 5 mm.
result;
FIG. 2 shows a dispersed state in the case where the width W5 mm of the baffle plate 15 and the number of the baffle plates 15 are 1, 2, and 3. The shutter speed is the above-mentioned fast case.
The shutter plate moves in the direction of the arrow.
(A21) is when there is no obstacle plate.
(A22) is the case where there is only one obstacle plate. The distance from the baffle plate and the baffle plate around the opening 12 to the farthest point in the right angle direction was 35.6 mm.
(A23) is the case where there are two obstacle plates. The distance between the baffle plates was 19.5 mm, and the distance between the baffle plate and the baffle plate having an opening of 12 circumferences to the farthest point in the perpendicular direction was 24.7 mm.
(A24) is when there are three obstacle plates. The distance between the baffle plates was 13.3 mm, and the distance between the baffle plate and the baffle plate having an opening of 12 circumferences to the farthest point in the perpendicular direction was 19.4 mm.

Similarly, in the actual machine, a cookie crushed product and a powder or granular material passed through a 4 mm mesh were tested in two ways at different shutter speeds.
FIG. 3 shows a dispersed state when the shutter speed is slow and when the shutter speed is faster than that.
This is a dispersed state when the width of the baffle plate 15 is W5 mm, the angle is 0 degrees (direction of D2), and the number of the baffle plates 15 is two.
(A31) is a case where the shutter speed is slow.
(A32) is a case where the shutter speed is high.

The following findings were obtained from the above tests of Examples 1 and 2;
The number of baffle plates 15 was slightly better for two than for one.
The width W of the baffle plate 15 was 3 mm and 5 mm, and there was no big difference. Therefore, considering the strength, 5 mm is considered to be better.
Regarding the operating speed of the shutter, it was confirmed that the higher the operating speed, the better the overall dispersibility.

As described above, it was found that by providing the baffle plate 15, the falling position of the powder or granular material 11 is dispersed on the object 17, and the powder or granular material 11 can be evenly and uniformly sprayed and supplied.

The method for producing the powder or granular material dispersion according to the embodiment will be described with reference to the flowchart of FIG. First, the powder / granular material dispersion supply device 10 described above is prepared (ST2).
Prepare the powder or granular material 11 (ST3). The shutter plate 14 is closed to receive the weighed powder or granular material 11 (ST4). In the powder / granular material dispersion supply device 10, the powder / granular material 11 is supplied to the weighing device (ST3). A predetermined amount of powder or granular material 11 weighed is supplied onto the shutter plate 14 in the closed state (ST5). An object 17 for dispersing the powder or granular material 11 is placed below the shutter plate 14 (ST6). The placement of the object 17 (ST6) may be performed when the opening 12 is closed by the shutter plate, and may be simultaneously performed with the supply of the powder or granular material 11 (ST5). Next, the shutter plate 14 is opened and the powder or granular material 11 is sprayed on the object 17 (ST7). The object (product as a powder or granular material dispersion) in which the powder or granular material 11 has been dispersed is sent out from the powder or granular material dispersion supply device 10 (ST8). If the production of the product is not completed, the process returns to the shutter plate closing step (ST4). When the production of the product is completed, the manufacturing process ends (ST10).

Specifically, for example, powders such as cocoa powder and cookies are evenly and evenly distributed and supplied to the surface of foods such as frozen desserts.

The opening 12 is not limited to a circular shape, but may be rectangular or patterned according to the shape of the object 17.

The material of the powder or granular material 11 is not limited, but for example, baked goods such as cookies, chocolate chips, nuts, dried fruits and their crushed products, and cocoa powder and powder can be sprayed on the upper surface of food. Examples include powders such as sugar and matcha.
The particle size of the powder or granular material 11 is preferably those that have passed through a mesh (sieve) of 1 to 8 mm, more preferably those that have passed through a mesh of 2 to 6 mm, and most preferably those that have passed through a mesh of 4 mm.
The object 17 to which the powder and granules 11 are sprayed is not particularly limited, and examples thereof include foods such as frozen desserts such as ice cream, high-moisture desserts such as chocolate, mousse and pudding, and baked confectionery such as cakes.
Food does not necessarily have to be in a container. The container may be pre-filled with food, or the food may be filled on the supplied powder or granular material 11.
Even powder particles having a wide particle size distribution can be uniformly sprayed and supplied.
The powder / granular material supply unit 13 has been described in the case of a flat plate-shaped powder / granular material supply plate, but the present invention is not limited to this, and the powder / granular material supply unit 13 may be like a frame as long as the baffle plate 15 can be provided. For example, the lower end of a tube for supplying powder or granular material such as a shooter may also be used.
