Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for crushing surimi, etc., which is mainly used in the manufacturing process of fish paste products.

Conventional technology For example, fish paste products such as kamaboko, chikuwa, and hanpen are put into a crusher containing the raw fish meat, ice water, salt, and other additives are also added, and after being stirred and crushed, it is formed into a predetermined shape. It is then heated and made into a product.

Up until now, the raw material for fish meat was to put the fish body through a meat harvesting machine, expose it to water, dehydrate it, and then put it into a crusher. It's getting far away,
Therefore, as described above, the meat is collected from the fish body, exposed to water, and dehydrated on a fishing boat, and the Surimi obtained in this way is quickly frozen and brought back as frozen Surimi. Frozen surimi is increasingly being used as raw fish meat that is crushed in a crusher.

Problems to be Solved by the Invention It is generally said that it is best to grasp and crush frozen surimi at a low temperature, and conventionally, frozen surimi is distributed at a temperature of about -20°C. Normally, the temperature is raised to about 3°C to -5°C, the surimi is crushed with a cutter, and then put into a mashing machine for mashing. In this case, the temperature further decreases with the addition of edible ice, and since the speed of mashing and stirring in conventional mashing machines is not very fast, there is a problem that small ice blocks are formed and the mashing effect is reduced. The main purpose of the present invention is to provide a grinding device that can efficiently grind frozen surimi while keeping the temperature still low.

Means for Solving the Problems The present invention has a crusher for crushing frozen material blocks into appropriate sizes while still frozen, and an input port for the frozen materials crushed by the crusher at the top. A plurality of scraping blades are provided in a substantially radial arrangement on a low-speed rotating shaft whose center is on the center line of a crushing container having a material discharge port at the bottom, and the plurality of scraping blades are stirred by rotation of the low-speed rotating shaft. The crushing member is configured to reside on the inner circumferential surface of the crushing container and rotate to mainly continuously stir the input frozen material, and the crushing member is attached to a plurality of dual-speed rotating shafts provided in positions within the crushing container that do not interfere with the low-speed rotating shaft. A crushing device is configured in combination with a crusher which is attached and a crushing member rotates at high speed with one rotation of the high-speed rotation shaft, and mainly performs continuous crushing, mixing, and crushing of input frozen materials. It is characterized by:

As described above, frozen material blocks at around -20°C are quickly crushed by a crusher into small pieces with a diameter of about 31 mm or less, placed in a crushing container, and crushed by multiple scraping blades. At low speed rotation, the cold material is evenly and continuously stirred as a whole, while multiple high-speed rotating shafts rotate at high speed, and the crushing member crushes, mixes, and crushes the frozen materials, quickly without freezing while remaining in a low-temperature state. It allows for accurate crushing.

It is composed of a plurality of (two in the illustrated embodiment) high-speed rotating shafts 15.1 to which a crushing member 16, which will be described later, is fixed so as to be replaceable.

The inlet 11 formed in the upper part of the pickling container 12 and the outlet 20 formed in the lower part are configured to be airtightly sealed by lids 10 and 19, respectively, and the lids 10 and 19 have one end pivoted to the machine frame. The opening/closing operation is performed by cylinder devices 10α and 19α, which are attached to each other and whose other ends are pivotally connected to covers 10 and 19, respectively.

Further, one side of the crushing container 12 (that is, the side opposite to the one side 12α through which the low-speed rotating shaft 13 and the high-speed rotating shafts 1s and 1s' pass through) has a door made of, for example, a transparent or translucent synthetic grease-resistant material. It is constructed so that it can be hermetically sealed and opened at 21.

The crushing member 16 fixed to the high-speed rotating shafts 1s and 15' includes a cutter 11 and a crushing rod 1 in the shape of a round bar, for example.
8 or a combination of both may be adopted.
- That is, the cutter 17 has its blade portion 17α cutting and pulverizing the frozen sliver by rotating the high-speed rotating shaft 15 in one direction, and the thick back portion 17b cutting and pulverizing the frozen sliver by rotating the high-speed rotating shaft 15 in the other direction. The crushing rod 18 in the shape of a round bar is connected to a high-speed rotating shaft 15.
The frozen surimi is strongly pounded and crushed by the high-speed rotation of the machine.

A water washing device 22 is provided on the upper part of the crushing container 12, and by operating a lever 23, a valve 26 is opened, and the cleaning water passes through a water pipe 25 and is squirted into the crushing container 12 from the water fountain 24. The inside can be washed with water.

Also, by opening the FP 27 and extracting the air inside the mashing container 12 through the pipe 28, the inside of the mashing container 12 can be made into a vacuum state, or by pressurizing air through the pipe 28, the inside of the mashing container 12 can be brought to a high pressure. It is now possible to make a state. (Furthermore, cooling spaces 29 and 30 are provided on one side and the outer peripheral surface of the crushed container 12.

The low-speed rotating shaft 13 is connected to a drive source 33 such as a low-speed variable speed motor.
The speed rotation shafts 15 and 15' are driven by drive sources 35 and 36 such as high-speed speed change motors.
are rotated via V-bells 37 and 38, respectively.

The rotational speed of each of the drive sources 33, 35 and 36 can be freely adjusted by operating the dial handles 39, 40 and 41, respectively.

Inserting again 1. Shredder 2. Shade 4. The outer peripheral surfaces of the screw conveyor 5, chute 8, etc. are covered with a heat insulating material to prevent cold air from the frozen surimi from being released to the outside. One of the toothed rolls 3, 3' is supported by a spring button so that the gap between the two toothed rolls 3, 3' can be adjusted.

In the above, the door 21 of the crusher 9 and the discharge port cover 19 are sealed, the input port cover 10 is opened, the outlet of the chute 8 is aligned above the input port 11, and the outlet of the chute 8 is placed above the input port 11. ? The frozen surimi block is supplied, and the crusher 2 and motor 6 are rotated. Then, the frozen surimi block, which is at a temperature of about -20° C., is quickly crushed by the crusher 2 into small pieces of about 3 mm in diameter or less, and sent from the shade 4 to the crushing container 12 by the screw conveyor 5. In this case, by providing #$51α in the axial direction on the inner peripheral surface of the five outer cylinders of the screw conveyor 5, the grooves 51α act as resistance and the frozen surimi can be accurately fed without causing rotation. be done.

If the crusher 2 is installed above the crushing container 12, the screw conveyor 5 is not necessary, and the frozen surimi crushed by the crusher 2 is directly supplied into the crushing container 12 from the input port 11. obtain.

When an appropriate amount of frozen surimi is prepared in this way and put into the mashing container 12, salt is added as an auxiliary raw material.

Add egg whites, mirin, starch, sugar, ice water, etc. to the type of fish meat, at
An appropriate amount is selectively put in depending on the type of product, etc., and after the chute 8 is rotated to a position where it does not get in the way of closing the lid 10, the lid 10 is sealed by a cylinder device 10α. As the cylinder devices 10g and 19α, for example, a screw feed type cylinder device in which a rod is screw fed by the rotation of a motor and operates in the longitudinal direction is adopted, and the rod to be screw fed and the connecting member to the lids 10, 19 are connected. A spring is interposed between them, and when the rod is extended and the lids 10 and 19 are closed, the spring acts on the lids 10 and 19 with a strong pressing force in the closing direction to maintain an airtight airtight state. It looks like this.

When the frozen surimi and auxiliary materials are put in as described above and the lid 1G is sealed, the drive source 33 rotates the low-speed rotation shaft 13 at a low rotation speed of 10 to 200 to 71. It rotates, for example, counterclockwise in the figure, at a rotation speed that is appropriately set depending on the type of product to be produced, etc., and a plurality of scraping blades 14 provided radially stay on the inner peripheral surface of the crushing container 12 and rotate. , the frozen surimi is continuously and evenly stirred, and the high speed rotating shaft 15.1 da is 200 to 400
In the high speed range of 0-, the shaft 15 to which the cutter 17 is attached, for example, rotates clockwise in the figure, and the frozen surimi that has been crushed into small pieces is further finely cut and crushed by the blade part 17g, and crushed by grinding. The shaft 1da to which a rod 18 is added rotates clockwise and the material is strongly pounded with the crushing rod 18 to mainly perform crushing, stirring, and crushing operations.

Further, the rotation direction of the shaft 15 to which the cutter 11 is attached is switched to the opposite direction, that is, counterclockwise, when the cutting and crushing of the material by the blade portion 11α is approximately completed, and the thick back portion 11b of the cutter 17 strongly crushes the material. Beating, crushing of VL, stirring 1 [
Do the destruction. In this case, if the thick back portion 17b of the cutter 11 is shaped to be somewhat rounded in the thickness direction, the machining can be performed smoothly.

Depending on the type of material, it may be better to attach cutters 17 to multiple high-speed rotating shafts 15.1 and perform cutting, crushing, stirring, and crushing by rotating the cutters 11 in the forward and reverse directions. In some cases, it may be better to attach the crushing rod 1B together with 1s and 15', and the cutter 17 may be used as the crushing member 16.

Using the crushing rod 18, or alternatively the cutter 17 and the crushing rod 1
8 and 8 can be arbitrarily determined depending on the type of material and the type of product to be manufactured. The shape of the crushing rod 1B is not limited to a round rod shape, but may be any shape.

During the mashing operation by the rotation of the high-speed rotary shaft 15, 15', the plurality of scraping blades 14 of the low-speed rotary shaft 13 continue to evenly and continuously stir the entire material in the mashing container 12, so that the frozen surimi is Even when the small lumps are mixed with salt, they do not freeze and can be completely crushed in a very short period of time while remaining at a low temperature.

This purpose can be easily achieved by inserting a cooling medium such as a chair, or if it is preferable to perform the mashing work in a vacuum according to the data, the mashing container 1 can be connected to the pipe 28.
If it is preferable to increase the amount of air in the pipe 2 or to perform the mashing operation under high pressure, the purpose can be achieved by pressurizing air from the pipe 2B.

When the crushing is completed, the receiving tank 42 is placed under the crusher 9, and the discharge port cover 19 is opened, so that the crushed materials are discharged to the discharge port 20.
It is discharged into the receiving tank 42.

When the discharge is completed, the discharge port cover 19 is sealed, and the input port cover 10 is closed.
After opening the chute 8 and passing the chute 8 over the input port 11, the crusher 2 and screw conveyor 5 are operated to input the frozen surimi block from the input port 1, and the same operation as above is repeated to perform crushing. .

The temperature of the material at the time of completion of gripping and crushing can be approximately 4° C. or lower.

When the day's work is finished, the fountain hole 2 is opened by operating the lever 23 and opening the valve 26 with the lids 10 and 19 closed.
Washing water is spouted into the crushing container 12 from 4, and the low speed rotating shaft 1
3 and high-speed rotating shaft 15. By rotating Is', the interior is almost completely cleaned.

Thereafter, the rotation of the rotating shafts 13, 15, 15' is stopped, the lids '10, 19 are opened, and the door 21 is opened to thoroughly clean the inside.

During the above-mentioned crushing operation, since the door 21 is made of transparent or translucent aluminum + resin, the processing state of the material inside can be checked from the nucleus crystals 21, and the high-speed rotation shaft 1
The forward rotation and reverse rotation of the 5, 1 da, low speed rotating shaft 13, etc. can be switched as appropriate.

Generally, the mashing time is set with a timer, and measures are taken to automatically stop the mashing after a predetermined time. A device is provided in which the drive sources 33, 35, and 36 are automatically brought out when such a situation occurs.

As the crusher 2, any type of crusher such as a toothed roll crusher using toothed rolls 3 and 3' as shown in the figure, a limited lath, or a show crusher, for example, can be employed.

Note that the present invention can be applied as a grasping and crushing device for any frozen object other than frozen fish meat.

Effects of the Invention As described above, according to the present invention, frozen material blocks are made into small pieces of appropriate size using a crusher, and this is fed into a crusher. Compared to shaving it with a frozen cutter and feeding it into the grinder in the form of sherbet, it is not only extremely efficient, but also allows the rent to be fed into the grinder at a fairly low temperature.
Grinding work can be carried out at low temperatures, and since the grinding work is carried out while continuously stirring the entire material using multiple scraping blades in the crushing container, low-temperature materials can be crushed while being crushed. It does not re-freeze and can be crushed accurately in a very short period of time, which can improve the efficiency of work and improve the quality of the dough, which can have great practical effects. It is.
