Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a frozen octopus processing apparatus that can perform thawing, washing, and base treatment of frozen octopus in the same apparatus.

[Prior art] Octopus is an essential part of the Japanese diet, and the proportion of octopus caught in the ocean is increasing. Such octopus is brought in in a frozen state and processed at a food factory, but pre-processing requires thawing, washing, and standardization, which are usually done as follows. There is.

The frozen octopus is made up of about 9 out of 10 to 20 blocks wrapped in plastic, etc. First, they are stored on the factory floor or in the outside yard.
Let it stand for an appropriate amount of time and thaw it by sprinkling water, etc. Once thawing has progressed to a certain extent, peel off the vinyl, etc., divide it into chunks of appropriate size, and put it into the cleaning and standard equipment. As an example of this cleaning/reference device, a wooden barrel-shaped container is rotatably supported on support shafts on the left and right side plates. Some have an opening covered with a flexible lid. Then, the thawed octopus is put in through this opening, a pose is inserted into the opening and water is poured in, the container is opened and the container is rotated to clean it, and the lid is opened and the container is tilted to open the opening. Discharge more waste water.

After repeating this several times to thoroughly wash the octopus, fill it with salt water and perform the standard marking in the same manner. This standard is used to massage the octopus to make it soft, moisturize the octopus, and improve its color and shape when boiled. The labeled octopus is removed from the container, cut into legs to ensure better boiling, sorted, and placed in the boiling pot.

[Problems to be Solved by the Invention] The above-mentioned thawing method requires a large space in a factory, and the time required for thawing is long and difficult to control, which has become a bottleneck in the processing process. In addition, the work of removing relatively large pieces of debris from thawed octopus and dividing them into small pieces and feeding them into a cleaning device is manual labor and is inefficient. Furthermore, since the weight to be handled is relatively large, it is easy to injure the lower back, which poses problems in terms of work hygiene.

In addition, the cleaning and standard equipment described above must be stopped and opened each time not only when loading and unloading materials, but also when supplying water for processing, and the equipment must be shut down while water is being supplied. There was a problem that the operating rate was low because it could not be moved.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a cylindrical container having a support shaft protruding from the left and right end faces, a bearing for supporting the support shaft, and the like. , a driving device for rotating the container is provided, the support shaft is formed hollow, and a water supply device for supplying water into the container and an air supply device for blowing gas into the container are connected to the support shaft. The structure is as follows.

[Operation] In such a processing device, thawing, washing, and standard preparation operations are all performed in the same device.

That is, a block of frozen octopus (hereinafter referred to as a frozen block) is introduced through the opening, water is supplied by a water supply device, and gas blown from the air supply device is ejected from the bottom of the container to agitate the water. Thaw while promoting heat exchange with the block. The water whose temperature has dropped is discharged from the opening, and at this time, garbage such as vinyl pieces whose specific gravity is lower than that of the water is removed together with the water. Next, the octopus is washed by closing the opening and rotating the container for an appropriate period of time, draining the waste water, and repeating this washing several times. After that, salt water is supplied instead of water and the base treatment is applied. , and then drain the octopus from the container.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

A water supply hose 21 is connected to the other support shaft 9 (hereinafter referred to as water supply shaft) via a rotary joint 20, and water is supplied into the container I by a water supply device (not shown) connected to this water supply port 21. It is supposed to be done.

On the inner wall surface of the container 1, there are blades 2 for stirring the contents of the container I.
2... is provided. The blades 22 are provided like shelves at positions that equally divide the wall of the container 1 in cross section (6 equal parts in the example), and are formed to become wider as they go from the center of the container 1 to the ends. The blades 22 are in alternate positions.

The blade 22 has an air chamber 23 which is hollow inside, and an appropriate number of pores 24 are formed in its ridgeline. A tube 25 and a radial tube 2 inside this ring-shaped tube 25
The air supply shaft 8 is connected to the air supply shaft 8 through the air supply system 6 and .

At the bottom of the container I, a discharge chute 27 for sending the octopus discharged from the container I onto the belt conveyor B is provided at an angle. This discharge chute 27 is composed of thin tubes 29 stretched vertically around a frame 28, and allows the octopus to flow smoothly and drains the moisture accompanying the octopus to the water storage hopper 30 below.
It is designed to be poured into water and drained.

An operation panel 31 is provided on the work floor Y for each processing device A, and this operation panel 31 allows the drive device 15 of the container 1,
It is possible to start, stop, or control the air supply device and water supply device.

Next, the operation of the refrigerating block processing apparatus configured as described above will be described.

First, the container 1 is tilted by operating the drive device 15 so that the opening 2 is positioned upward (hereinafter referred to as the normal position), the sealing lid 4 and the draining plate 3 are opened, and the freezing block is put in.

At this time, in order to prevent impact to the container 2S1, the water supply device is activated in advance to fill the inside of the container 1 with water. Freezer blocks are loaded from the work floor Y, but as shown in Fig. 1, the height of the work floor Y is almost the same as the support shafts 8 and 9 of the container 1, and when the container 1 is tilted, It can be directly loaded from a trolley, etc. Next, with the opening 2 open, the container 1 is tilted so that the opening 2 comes to the water's edge, the water supply device is activated to supply water into the container 1, and the air supply device is activated to increase the capacity. Gas is ejected from the pores 24 of the bottom blade 22. This jet of gas stirs the water to create a water flow, and the container! It eliminates temperature imbalances within the block to prevent residual melt, and improves heat conduction between the frozen block and water to speed up thawing. It is desirable that the water supplied here be moderately warm water (for example, well water). At this time, along with the overflowing wastewater, lightweight garbage such as plastic pieces that have covered the freezing block is removed.

In this example, water overflows from the opening 2 and is discharged during thawing as described above, but in order to further improve the thawing efficiency of the water, there is a container 1 at the bottom in its normal position that can be opened and closed. A drainage port may also be provided.

The amount of water and air supplied are variable depending on the amount processed per frozen block, water temperature, etc., and do not need to be constant during the processing time, but can be changed based on experience to find the most efficient Furthermore, sequence control may be performed using a microcomputer or the like.

The octopus, which has been thawed to some extent after the above steps, is washed as follows. For cleaning water, use the same water used for thawing or replace it. When replacing the container, hold the container l until the opening 2 part 2 is on the lower side.
(hereinafter referred to as the reverse position) to drain only water through the drain plate 3. Thereafter, the cleaning is performed by operating the drive device I5 to rotate the container I and stirring the octopus and water using the blades 22, and two types of cleaning can be performed: a batch type and a continuous type. The former is done with the sealed M4 closed and without water supply.
After an appropriate time, the container 1 is stopped in the reverse position and drained. At this time, trash such as sand that has a higher specific gravity than water is discharged. Repeat this process an appropriate number of times to complete the cleaning. on the other hand,
The continuous type supplies water while rotating the container l, and
Open at least one seal M4 of the opening 2, and
When the water is placed on the lower side, water is drained through the drain plate. There are also methods intermediate between the two, such as a method in which the beginning and end of a batch method are performed continuously. In the above, it is optional whether or not to use an air supply device. As the container I rotates, the octopus inside is lifted up by the blades 22, and when the blades 22 tilt to a certain degree or more, they fall. The timing of the octopus falling on the left and right sides is different, which improves the stirring effect without crowding the octopuses.

After the cleaning process is completed, the standard process is continued.

In this standard treatment, the above-mentioned cleaning treatment is performed using salt water, and it is possible to supply salt water that has been dissolved in water in advance, or to place the container 1 in the correct position and seal M4, and to open the drain plate 3 and pour in the salt. You may. In the reference processing, the use or non-use of an air supply device is optional, and the effect is improved by alternately arranging the blades 22. In addition, in the above-mentioned cleaning and standard processing, an appropriate rotational force method and rotation speed of the container 1 may be adopted. For example, in addition to normal one-way rotation, reversal at appropriate intervals, or Possible methods include rocking the shaft without fully rotating it.

After the reference processing is completed in this manner, both the sealing lid 4 and the draining plate 3 of the opening 2 are opened, and the container 1 is placed in an inverted position. The octopus and salt water are discharged onto the discharge chute, the moisture falls into the water storage hopper 30, and the octopus slides on the thin tube 29 and is sent to the belt conveyor B, and is further transferred to the next process.

Note that the above-described apparatus and method are examples of implementing the present invention, and the present invention is not limited to the above. For example, the water supply and air supply devices may be connected to the same support shaft 8.9, or the support shaft 8.9 may be connected directly to one support shaft and another vane 22 may be provided around it. Although the blades 22 are alternately arranged on the left and right sides, they may be further divided in the longitudinal direction of the container 1, and their shape may be curved or have a curved surface. In addition, an opening/closing device such as a sealing M4 is installed, and the container l
It is also possible to automate the operation by installing a tilt position detector or the like.

[Effects of the Invention] As detailed above, the present invention comprises a cylindrical container having a support shaft protruding from the left and right end faces, a bearing that supports the support shaft, and a drive device that rotates the container. The support shaft is hollow, and the water supply device that supplies water into the container and the air supply device that blows gas into the container are connected to this support shaft. The octopus block can be thawed, washed, and treated as a standard.
