BACKGROUND OF THE INVENTION
The present invention relates to a production apparatus for producing a mixed powder obtained by mixing auxiliary ingredients such as sugar and fats and oils with wheat flour as a main component, and in particular, a crusher with improved processing speed and production of mixed powder using the same. Relates to the device.
[0002]
[Prior art]
Mix powder is a product with ingredients adjusted in advance such as powder for hot cakes and powder for okonomiyaki, usually adding a predetermined amount of oil and fat and various auxiliary ingredients to wheat flour as the main component, mixing in a mixing device, They are subdivided and filled into bags or placed in lorries. In this case, it is necessary to mix the components sufficiently with a mixing device so that the components do not vary among the packaged products and the components are not biased inside the lorry.
[0003]
A conventional mixed powder production apparatus is shown in FIG. As shown in FIG. 5, the mixed powder manufacturing apparatus 100 is mixed by a mixing apparatus 8 that mixes raw materials, a bottle 4 as an input apparatus that inputs main raw materials such as flour into the mixing apparatus 8, and the mixing apparatus 8. The crusher 80 crushes the “dama” of the product, the storage device 9 that stores the product, the filling device 12 that divides and fills the product, and the like.
[0004]
In order to produce the mixed powder, first, a predetermined amount of wheat flour and other auxiliary materials such as sugar, fats and oils, baking powder and the like are charged into the mixing device 8, and the mixing device 8 is operated and mixed. When mixing is completed, the mixture is sent to the crusher 80, and the “dama” generated by the mixing action of the mixing device 8 and the “dama” that could not be crushed are crushed by the crusher 80 and sent to the storage device 9 for storage. . From there, it is mixed again or mixed, adjusted uniformly, sent to the filling device 12 and packed in small portions, or sent to a lorry (not shown).
[0005]
That is, especially in the case of mixed powder with a high content of fats and oils, a lump called a “dama” is likely to be produced by the mixing process, and the “dama” is sent to the next storage process. A crusher 80 such as a pre-mill, a hammer mill, a turbo mill, or the like was installed between the storage devices 12, and the "dama" was crushed to eliminate unevenness of components. In the crusher 80, for example, a large number of metal blades are rotatably provided on the upper part of a semi-cylindrical screen, and the metal blades are rotated on the screen to crush the “dama” and open the screen. The mixed powder was passed through the holes for processing.
[0006]
However, the crusher 80 of this type has a small processing capacity, and the adhesion force is increased by the contained fats and oils, the processing capacity is further reduced, and the processing speed is slower. Moreover, the size of the device was large, and the noise accompanying the rotation was excessive. In view of this, it has been considered to use a crusher called a comil, which is provided with a rotating member that rotates along the screen inside the conical screen, thereby breaking the “dama” through the aperture of the screen. According to this apparatus, there is an advantage that the size is smaller and the noise level is smaller than the processing capacity.
[0007]
[Problems to be solved by the invention]
However, even the above-mentioned combil type crusher has insufficient processing capacity per hour, and it takes time for the processing in the crushing process. In the mixed powder manufacturing apparatus, the amount of processing at a time including the main raw material such as wheat flour and other auxiliary raw materials is several hundred kg to 1 ton or more, and this is first put into the mixing device 8 and mixed. Yes. The mixing operation in the mixing device 8 is performed for a predetermined time. When the mixing operation is completed, the mixed powder is sent from the mixing device 8 to the crusher 80 and crushed. Since the product mixed by the mixing device 8 is sequentially fed into the crusher 80 according to the processing capacity of the crusher 80, if a lot of time is spent on the processing in the crusher 80, the crushing capacity is increased. It became rate-limiting, and the processing capacity of the entire mixed powder production apparatus was limited.
[0008]
Furthermore, when a variety of raw materials are charged into the mixing device 8, the raw material is vibrated using a vibrating screen, and it takes a lot of time to process the vibrating screen. In addition, it was an obstacle to shortening the processing time of the entire mixed powder production apparatus.
[0009]
An object of the present invention is to solve the above-mentioned problems and to provide an apparatus for producing a mixed powder with an improved production processing speed.
[0010]
[Means for Solving the Problems]
The present invention is configured as follows in order to solve the above-described problems.
[0011]
That is, the inventors require a lot of time for processing because the passage of flour or the like in a conventional crusher or a vibrating sieve is allowed to fall due to the weight of the powder itself, and the “dummy” is caused by a rotating member or vibration inside the apparatus. It was noticed that even though the powder was crushed so that it could pass through the screen, it took time to pass through the screen by its own weight because the powder itself was light. Thus, the outlet side of the crusher or vibrating sieve is decompressed with respect to the inlet side, and suction force to the outlet side is applied.
[0012]
Specifically, the inside of a device to which a vibrating sieve or a comil type crusher was connected was depressurized, and a negative pressure was applied to the exit side of the vibrating sieve or a comil type crusher.
[0013]
In this way, by bringing the outlet side to a negative pressure and causing a suction action, the powder that can pass through the screen can be quickly passed through the screen, and the processing speed can be increased. As a result, the amount of raw material passing through the screen per unit time increases, the processing capacity per hour in the crusher and the vibrating sieve can be increased, and the manufacturing processing speed of the entire mixed powder manufacturing apparatus can be significantly improved.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a mixed powder production apparatus according to the present invention will be described.
[0015]
FIG. 1 shows the entire mixed powder production apparatus 2. The mixed powder production apparatus 2 includes a bin 4 as a charging apparatus, a vibrating sieve 6, a mixing apparatus 8, a crusher 10, a storage apparatus 9, a filling apparatus 12, and the like.
[0016]
The bin 4 is a storage device that mainly stores flour, and opens and closes a discharge port provided in the lower portion of the container to discharge a predetermined amount of flour and the like. Further, a scale 35 for measuring the entire weight is attached to the bin 4, and the weight of the discharged flour or the like is obtained by measuring the total weight before and after the discharge of the flour or the like.
[0017]
The vibrating sieve 6 includes a sieve and a vibrating mechanism that vibrates the sieve. The vibrating sieve 6 vibrates the auxiliary material and the like put in the sieve and puts them into the mixing device 8. Moreover, the vibrating sieve 6 may be provided at the discharge port of the bin 4 and the flour discharged from the bin 4 may be vibrated and input. In addition, the mixing device 8 is provided with a pipe 14 into which a liquid auxiliary material such as oil or fat is charged.
[0018]
The mixing device 8 is sealed inside and kept airtight. Further, the vibrating sieve 6, the pipe 14, and the suction pipe 22 from the decompression pump 20 are airtightly connected to the mixing device 8. In addition, a discharge port 17 is provided at the lower portion of the mixing device 8, which is opened and closed by an open / close valve, and sends the mixed powder mixed to the crusher 10.
[0019]
The crusher 10 is a crusher called a comil. As shown in FIG. 2, a frustoconical screen 32 is provided inside an outer container 30, and a rotary shaft 34 is attached coaxially with the central axis of the screen 32. It has been. The rotating shaft 34 is provided with a blade 36 as a rotating member substantially in contact with the inner surface of the screen 32, and the blade 36 is rotated at a predetermined rotational speed by a drive mechanism (not shown). A large number of holes having a predetermined diameter are formed in the screen 32, and the distance between the blade 36 and the screen 32 can be adjusted as appropriate. A discharge port 38 is provided at the lower portion of the outer container 30, and the discharge port 38 is airtightly attached to the storage device 9.
[0020]
The storage device 9 is configured to be airtight inside, and a decompression pump 20 is connected via a suction pipe 22. A discharge port 19 is provided at the lower portion, and is connected to the filling device 12 through the discharge port 19. Note that the storage device 9 and the filling device 12 may be connected via a vibrating sieve, and the mixed powder may be vibrated and sent to the filling device 12. The filling device 12 is a device for filling the mixed powder into various containers such as predetermined bags.
[0021]
Next, the operation of the manufacturing apparatus 2 will be described.
[0022]
First, the decompression pump 20 is operated to reduce the pressure inside the mixing device 8 and the storage device 9. If each inside is maintained in a predetermined reduced pressure state by the action of the vacuum pump 20, a predetermined amount of flour is put into the mixing device 8 from the bottle 4. The charging is carried out gradually, and if a vibrating sieve is installed, it is supplied through the vibrating sieve. Further, for example, saccharides, milk powder, and the like are similarly supplied from another vibrating sieve 6 provided in the mixing device 8. The vibrating sieve 6 vibrates a sieve (none of which is shown) by a vibrating mechanism, and drops the powder charged in the sieve into the mixing device 8. Further, a predetermined amount of fats and oils is supplied from the pipe 14 to the mixing device 8.
[0023]
Since the inside of the mixing device 8 is depressurized, a suction force acts on the lower portion of the vibrating sieve 6 and the processing ability of the sieve is improved, so that the powder dropping ends in a short time. At this time, in order to enhance the suction effect by the reduced pressure, it is preferable to put the powder on the entire surface of the sieve.
[0024]
When all the predetermined raw materials have been charged, the vacuum pump 20 is stopped and the mixing device 8 is operated. In addition, you may make it supply a raw material at any time, mixing. Inside the mixing device 8, a stirring rod, a stirring blade, etc. (not shown) rotate, reciprocate, etc., and the charged raw materials are stirred up and down, left and right, and mixed sufficiently. When a plurality of raw materials are mixed for a predetermined time by the mixing device 8, the operation of the mixing device 8 is stopped, the open / close valve is opened, and the mixed powder mixed from the discharge port 17 is sent to the crusher 10.
[0025]
In the crusher 10, when the mixed powder is introduced from the mixing device 8, the blade 36 rotates, and when there is “dama” in the product, it is crushed and dropped through the screen 32. In the crusher 10, the discharge port 38 is attached to the storage device 9 in an airtight manner, and the inside of the storage device 9 is decompressed by the decompression pump 20, so that a suction force acts on the lower side of the screen 32. With this suction force, the crushing process can be performed promptly.
[0026]
The mixed powder whose “dama” has been crushed by the crusher 10 is put into the storage device 9 and stored. The storage device 9 may mix again in the same manner as the mixing device 8. Thereby, the nonuniformity of a component can be eliminated and the component of a mix powder can be made more homogeneous.
[0027]
The mixed powder stored in the storage device 9 is discharged from the discharge port 19 at any time and sent to the filling device 12. In addition, a vibration sieve may be provided on the upstream side of the filling device 12 and the powder may be sent to the filling device 12 by applying vibration. In the filling device 12, the mixed powder is sequentially filled into a predetermined bag or the like.
[0028]
Thus, according to the manufacturing apparatus 2, the processing speed in the crusher 10 or the vibration sieve 6 can be improved by reducing the pressure at the discharge port side of the crusher 10 or the vibration sieve 6, and the processing for the entire production of the mixed powder. Time can be significantly reduced.
[0029]
【Example】
Next, an experimental example will be described with reference to the drawings.
[0030]
FIG. 3 is a comparison of processing times using a vibrating sieve. In the experiment, weak flour is used, the upper part of the table is a normal treatment, and the lower part is a result of suction. The degree of vacuum for suction is 60 mmH ₂ O. From the table, it can be seen that when aspiration is performed, the throughput is about 1.7 times that of the standard.
[0031]
Moreover, the experimental result by a crusher is shown in FIG. The experiment was conducted by using a standard powder and a process with suction applied to each of a weak powder, a strong powder containing 8% oil, and a corn starch containing 15% oil. The degree of vacuum for suction is 50 to 60 mmH ₂ O. From the table, it is understood that the processing amount is 840 to 600 kg / h in the standard, but when the suction is applied, the processing amount is three times or more.
[0032]
【The invention's effect】
According to the mixed powder manufacturing apparatus of the present invention, since a comil type is used for the crusher, the manufacturing apparatus can be reduced in size, noise associated with the crushing process can be reduced, and a crusher, a vibration sieve, etc. Since the discharge port side is depressurized, the processing speed of the powder in the crusher and the vibration sieve is increased, and the entire required time in the mixed powder manufacturing apparatus can be greatly shortened.
