Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crusher, stirrer, and crusher used primarily in the manufacturing process of fish paste products.

For example, fish paste products such as kamaboko, chikuwa, hanpen, and kaniashikaze kamaboko are made from fish meat obtained by harvesting the raw fish using a butcher, exposing it to water, dehydrating it, and crushing the fish meat. After stirring and crushing, each product is given a unique shape and flavor, and then heated in an appropriate manner to make the product.

Currently, the grinding of fish meat in the above process is done by first pulverizing the frozen surimi using a cutter, then exposing it to water for dehydration, and leaving the unfrozen fish as it is. It is generally carried out using a crusher combined with a shaped pestle.

In other words, in the conventional grinding machine, finely minced fish meat or raw fish meat that has been exposed to water and dehydrated is placed in a rotating mortar, and the pestle rotates inside the mortar in the opposite direction to the mortar. It is designed to stir and crush the raw materials for the paste product.

However, such conventional grinding machines not only have problems in terms of work efficiency, but also the top surface of the Surimi inside the bowl-shaped mortar remains exposed to the atmosphere during the grinding process, making it difficult to work in the workplace. There are many other problems, such as the difficulty in managing the overall hygiene of the meat, and the need to lower the temperature of the fish during mashing in order to prevent the fish meat from slithering (a phenomenon in which the fish meat gels and loses its fluidity). ing.

The present invention provides a crushing, agitating, and crushing device capable of solving the problems of the prior art as described above, and will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a mortar body, 2 is a rotating shaft rotatably supported by a bearing at the bottom of the bottom plate of the mortar body, 3 is a bottom plate, and 4 is a bearing. The rotating shaft 2 is connected to a motor 5 via a motor shaft pulley 6, a V-belt 7, and a rotating shaft pulley 8. The rotating shaft 2 is rotated by the rotation of the motor 5. A cutter 9 is fixed to the rotating shaft 2, and the cutter 9 has a twisted structure with respect to the rotating surface.By rotating the cutter 9 in one direction, it cuts and crushes the material inside the mortar body 1, and simultaneously cuts and crushes the material in the mortar body 1. The cutter 9 is configured to send out the cut and crushed material in one direction (in the illustrated embodiment, downward direction) by twisting the cutter 9.

In the illustration, the device for feeding downward is a cutter with a twist. If the material does not need to be cut or crushed at all, instead of a cutter with a twist, you may use a spiral cutter that sends the material downward, or a blade that sends the material downward.

In the lower part of the mortar container, there is a bottom part 34 of the mortar body 1 on the bottom plate 3, on which a sloped surface whose surface slopes downward from the center toward the outer periphery is formed. Non-rotating sliding surface 10 on the lower inside of the container
It is. Although this non-rotating sliding surface 10 is shown as an inclined surface, it can be made horizontal or spherical depending on the material and the degree of crushing.

Of course, the center of the non-rotating sliding surface 10 is the same as the center of the rotating shaft 2.

Depending on the data, it is often better to provide radial grooves on the non-rotating sliding surface 10 as shown in 11 in FIG.

When crushing a material into ultra-fine shapes, it is better to form ultra-fine irregularities on the non-rotating sliding surface 10.

The non-rotating sliding contact surface 10 also generates frictional heat due to sliding contact, so a cooling space 2 is provided to cool this heat.
The non-rotating sliding surface 10 can be cooled through a pipe 23 which forms a space 20 and allows a cooling medium such as cooling water or cold air to flow through the space 20.

In addition, the material of the non-rotating sliding contact surface 10 may be metal, stone,
Of course, the material should be selected according to the material to be crushed, such as pottery or resin.

The rotating sliding surface 14 that slides on the non-rotating sliding surface 10 described above is formed on the lower side of the rib 13 on the outer periphery of the boss 12 fitted to the rotating shaft 2 .

Of course, the rotating sliding contact surface 14 is matched to the shape of the non-rotating sliding contact surface 10. The material should be selected according to the material (metal, resin, ceramic, wood, etc.).

Also, it goes without saying that the unevenness of the rotating sliding contact surface 14 should be selected in accordance with the material.

The rotating sliding contact surface 14 has a boss 1 fitted onto the rotating shaft 2.
It is important that the shape of the rib 13 on the lower surface of the rib 13 of No. 2 is such that when it is rotated by the rotating shaft 2, the material can be easily fed in the most appropriate amount between the opposing sliding surfaces. As an example, radial ribs 13 as shown in FIG. 2 may be used.

Rib 13 on the outer periphery of the boss 12 fitted to the rotating shaft 2
If the feeding device that sends the material along the rotating shaft 2 to the non-rotating sliding surface 10 by the rotation of the rotating shaft 2 is a spiral feeding device, a boss 12 whose lower end of the spiral fits into the rotating shaft 2 is used. In many cases, the outer circumferential ribs 13 of the two are almost identically formed.

When the material passes through the gap between the rotating sliding surface 14 and the non-rotating sliding surface 10 due to the rotation of the rotating shaft 2, the gap between the rotating sliding surface 14 and the non-rotating sliding surface 10 tends to widen. The sliding contact surface 1 rotates via a spring 15 to create the most suitable pressure for the material.
A boss 12 with four ribs 13 moves up and down along the rotating shaft 2 to adjust the sliding contact pressure.

Reference numeral 16 denotes a reinforcing ring attached to the upper end of the outer periphery of the upper rib 13 of the rotating sliding contact surface 14.

In addition, in the illustration, the sliding contact gap between the rotating sliding contact surface 14 and the non-rotating sliding contact surface 10 is adjusted by moving the rotating sliding contact surface 14 up and down. It is also possible to adjust the gap between the sliding surfaces by moving the parts of the sliding surfaces 10 that are fixed and do not rotate up and down.

The gap between the non-rotating sliding contact surface 10 and the rotating sliding contact surface 14 has a sliding contact or a small gap (the gap varies depending on the fish meat that is the raw material for the seafood paste product, but approximately 0 to 7 m/m is appropriate). It has a structure.

The nut 17 is tightened into the threaded portion 18 of the rotating shaft 2 to fix the cutter 9 and maintain the fitting of the mounting boss 12 on the rotating sliding contact surface 14 with a constant gap. Incidentally, corners 21 and 22 are provided on the upper surface of the outer periphery of the nut 17 to assist in crushing solid materials such as frozen surimi.

Reference numeral 19 denotes a cooling space formed on the outer peripheral surface of the mortar body 1, in which a cooling medium such as cooling water or cold air is allowed to flow, or solid cooling such as ice or dry ice is allowed to flow inside the space 19. It is now possible to fill with media.

24 is a lid body that airtightly seals the upper part of the mortar body 1;
The lid body 24 is provided with an inlet 25 and an inlet valve 26, and is also provided with a scraping member 28 that is rotationally driven by a motor 27. 1 and the lower surface of the lid body 24 at low speed (5~
(approximately 100 rpm) to constantly or occasionally scrape off material adhering to the inner periphery of the mortar body and the lower surface of the lid body. The lid body 24 has a structure that can be opened and closed around the hinge center 29, and the scraping member 28 is always stopped at a position substantially lateral to the hinge center 29 side by a limit switch 30, and when the lid body 24 is opened, the scraping member 28 is The shielding member 28 is arranged so as not to get in the way.

A material discharge port 31 is provided at the bottom 34 of the mortar body 1, and the discharge port 31 is hermetically sealed with a discharge port cover 32. The outlet cover 32 is removed using a removal handle 33.

In the above process, a material (surimi, etc.) is put into the mortar 1 and the motor 5 is rotated. Then, the rotary shaft 2 rotates via the pulley 6, the belt 7, and the rotary shaft pulley 8, and the cutter 9 rotates to cut and crush the material, and at the same time, the cut and crushed material is sent downward by the twisting motion of the cutter. The material sent downward along the rotating shaft is pressed downward against the non-rotating sliding surface 10 by the upper rib 13 of the rotating sliding contact surface 14, and at the same time, the material is pressed against the rotating sliding surface 14 and the non-rotating sliding surface 10. Due to the relative rotation difference between the sliding contact surface 14 and the unevenness of the sliding contact surface, the radial ribs 13 of the rotating sliding contact surface 14 and the radial grooves 11 of the non-rotating sliding contact surface 10 are guided, etc. The material is scattered radially to the outer periphery, and is sent downward by the cutter 9 to the inner peripheral surface of the mortar body 1 together with the material that directly rises without passing between the non-rotating sliding surface 10 and the rotating sliding surface 14. In this way, the material is circulated up and down inside the mortar body 1, and the material adhering to the inner peripheral surface of the mortar body 1 and the lower surface of the lid body is scraped off by the scraping member 28, and crushed and agitated. be crushed.

The rotational speed of the rotating shaft 2, that is, the cutter 9, and the rotating sliding contact surface 14 is determined by the diameter of the cutter, the blade thickness, the number of blades, the number of stages of the cutter 9 (two stages are shown in the figure, but any number of stages greater than one can be adopted), Other rotating sliding contact surface 14
The shape, number, material, height, thickness of the upper ribs,
Although it varies depending on the shape, material, height, and quality of the material of the non-rotating sliding surface 10, it is generally desirable to be able to freely control the speed within a range of about 200 to 3000 rpm. The sliding contact interval between the rotating sliding contact surface 14 and the non-rotating sliding contact surface 10 is normally set to 0 if there is no material, but if the material to be crushed does not require fine crushing, stirring, or crushing. An appropriate spacer can be adjusted by adjusting the thickness of the washer 35 under the boss 12 fitted to the rotating shaft 2, but in the case of fish meat, which is the raw material for fish paste products, 0 is preferable.

When the rotary sliding contact surface 14 rotates due to the rotation of the rotating shaft 2 and the material passes through it, it is preferable to insert a spring 15 that matches the sliding contact pressure of the material passing through. If the spring 15 is too strong to match the material, the material will fall on the rotating sliding contact surface 14.
If the spring 15 is too weak, a large amount of material may get between the rotating sliding contact surface 14 and the non-rotating sliding contact surface 10, and the purpose of crushing may not be achieved sufficiently. Therefore, the strength of the spring 15 should be selected according to the material and the degree of crushing, and the number of rotations of the rotating shaft 2, angle of inclination, shape, and material of each sliding surface should be set before work. It is.

To operate this machine, generally tighten the lid 24 with the screw 3.
The rotating shaft 2 will not rotate unless it is tightened at 8.

During the above-mentioned crushing, stirring, and crushing work, the input port 25
Normally, the valve 26 is opened to add additives for seasoning, etc., but depending on the material to be ground, the speed of rotation is fast and the grinding time is greatly shortened, so it is possible to reduce the grinding time by a large margin. , any additives such as water may be added first.

If the rotation speed is high, the temperature inside the mortar will rise quickly, so you should be especially careful.When using this machine in the process of manufacturing fish paste products, the thermometer 36 in the data inside the mortar 1 should generally be around 15℃. When this happens, the switch 37 of the motor 5 is automatically shut off.

Furthermore, it is desirable to keep the temperature of the fish paste product at a low level during mashing to prevent slivers.

In the present invention, a cooling space 19 is provided on the outer peripheral surface of the mortar body 1.
For example, by forming the cooling space 19 with a double-body multi-structure, etc., and by taking measures such as flowing a cooling medium such as cold air or cold water into the cooling space 19, or filling it with a solid cooling medium such as ice or dry ice. You can easily keep the temperature of the material at a low level.

Furthermore, in this machine, the temperature rise of the opposing sliding contact surfaces of the rotating sliding contact surface 14 and the non-rotating sliding contact surface 10 is the biggest problem, so a cooling space 20 is provided to cool the non-rotating sliding contact surface 10 to reduce the temperature of the material. If it is desired to prevent the temperature from rising, the temperature rise due to the sliding contact between the sliding surfaces can be kept at a low level by passing a cooling medium such as cooling water or cold air.

When the grinding, stirring, and crushing (additional mixing of additives, seasoning, etc.) is completed, the outlet cover 32 is removed by operating the handle 33 and the outlet 31 is opened. Then cutter 9
The material is almost completely discharged from the discharge port 31 by sending the material downward by the rotation of the rib 13 of the rotating sliding contact surface 14 and by scraping the material by rotating the scraping member 28.

Next, the rotation of the motors 5 and 27 is stopped, the tightening bolt 38 of the lid body 24 is removed, the lid body 24 is opened, and the material attached inside the mortar body 1 is completely removed.

In the case of fish paste products, it is ideal to perform crushing, stirring, and crushing in a vacuum or near-vacuum conditions, but in the case of the present invention, the mortar body cover 24 is closed before the crushing, stirring, and crushing operations are started, and the discharge port is closed. 31 with the outlet cover body 32 and the valve 26 of the additive inlet 25 is also closed, the inside of the mortar body becomes a completely closed space. By removing air from the air extraction port 39, the entire inside of the mortar body 1 can be easily vacuumed or Grinding, stirring,
It can be crushed and a soft paste product can be obtained.

Conversely, depending on the type of material, it may be crushed under pressure,
There may be cases where it is better to perform stirring or mashing, but in this case, the interior can be easily pressurized by supplying air pressure from the air extraction port 39.

After the work is completed and all materials have been discharged, close the lid 24 and the discharge port cover 32 of the discharge port 31, fill with water, rotate the rotating shaft 2 and scraping member 28 for about 1 minute, and then turn the By stopping the discharge port 31 and removing the discharge port cover 32 to allow the discharge to flow out, the inside of the mortar body 1 can be almost completely cleaned.

In the above embodiment, the rotating sliding contact surface 14 and the rib 13
As mentioned above, the sliding contact surface 10 that does not rotate varies depending on the type and purpose of the material, and in the case of fish paste products, the interval between the rotating sliding contact surface 14 and the non-rotating sliding contact surface 10 is 0, and the sliding contact surface The shape of the ribs 13 of the rotary sliding contact surface 14 is radial as shown in FIG. The non-rotating sliding contact surface 10 has the appearance of a polished granite surface, and it is better to make the radial grooves 11 very shallow and rough as shown in the second figure. The material should be made of stainless steel.

In addition, in the illustrated embodiment, the lower sliding surface 1 that does not rotate
Although the cutter 9 is used as the feeding device for feeding the paper to the 0, a spiral feeding device may be used depending on the material. The rotating sliding contact surface 14 may also have a helical end. Alternatively, the feeding device for sending the material to the non-rotating sliding surface 10 in the lower part may be a blade.

Although the rotating sliding surface 14 is shown to be able to move up and down via a spring 15, the sliding surface 10, which does not rotate, may be moved up and down without moving the rotating sliding surface 14 up and down using a spring or the like. In the illustration, the rotating sliding contact surface 1
4 has a radial shape, but it may be perpendicular to the rotation axis 2, and the sliding surface 14 should be selected to have a shape suitable for the material, such as a flat or spherical surface.

The rotation speed of the rotating shaft 2 can be arbitrarily set using the rotation speed variable handle 40 of the motor 5. Scraping member 2
8 can also be arbitrarily set using the handle 41.

In order to rotate the rotating shaft 2 slightly by hand while the rotating shaft 2 is stopped, a clutch 43 may be provided inside the pulley 8 to connect the pulley 8 and the rotating shaft 2.

Although the illustrated embodiment shows an example in which the mortar body 1 is bowl-shaped and the rotating shaft is provided in the center, the mortar body 1 may also be shaped like a cone, a dish, a cylinder, etc. The contact surface 10 may also be mounted eccentrically from the center of the mortar body 1.

The crushing, stirring, and crushing apparatus of the present invention is not limited to the upward position as shown in the drawings, but may be used in a slightly inclined position or in a horizontal position.

As described above, according to the present invention, it is possible to efficiently crush, stir, and crush materials in an extremely hygienic manner, and when necessary, it is possible to easily crush, stir, and crush materials under vacuum, pressure, and low-temperature conditions. This is something that can be done and can bring about great practical effects.

It goes without saying that the apparatus of the present invention can be applied to the process of crushing not only fish paste products but also all materials.
