BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thawing machine for efficiently thawing frozen fish.

[0002]

2. Description of the Related Art Conventionally, when thawing frozen fish, the frozen fish are put in a water tank and taken out after a lapse of a certain time under a stirring condition of water flow.

[Problems to be Solved by the Invention] In the above-mentioned taking-out work, there is a problem that thawed and unthawed items are mixed and taken out, and if it takes a lot of time to solve this, There is a problem that the freshness of the already thawed product is reduced. SUMMARY OF THE INVENTION The present invention solves the above problems and provides a device for efficiently extracting thawed products in sequence.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a fumarole having a large number of air ejection holes is laid on the bottom of a rectangular parallelepiped water tank, and the length of the tank bottom is slightly above the fumarole. A conveyor having a mesh-like carrier belt and having an L-shape is arranged rotatably from one end to the other end in the vertical direction, and is not movable on the tank through the elevating means. In addition, when the conveyor is located in the water tank, a box frame at the bottom is formed in a number of comb-like notches m upward at a certain height above the conveyor, and thin rods are provided for the comb-like notches. Vertical as appropriate
Forming a mesh plate that can be fitted in the lateral direction to obtain a mesh spacing of any size, and constructing columns that are erected at the four corners of the mesh plate so that they can be attached to and detached from the upper edge of the water tank. Is characterized by.

[Function] Frozen fish put into the water tank does not settle below the mesh plate initially, but as the freezing progresses, it sinks downward from the mesh plate interval and is received by the conveyor rotating at the bottom of the tank. It will be taken out. At this time, the mesh frame of the mesh plate
Are formed in a number of comb-shaped notches toward the
For the type and size of the fish, insert a thin rod in the vertical and horizontal directions as appropriate.

1 is a perspective view of the device of the present invention, and FIG. 2 is a central sectional view of the same. Reference numeral 1 denotes a rectangular parallelepiped water tank having a constant height h, and a fumarole tube 3 having a large number of air ejection holes 2 on the bottom surface.
Is laid, and air is ejected by the operation of a drive pump provided in the drive chamber 4.

Reference numeral 5 denotes an overflow slit formed on the upper side wall of the water tank, and an air jet pipe for appropriately generating a necessary water flow is provided at a proper position in the water tank so as to branch from the fumarolic pipe 3. That is, in the illustrated example, fumaroles 6 and 7 are provided so as to make a circulatory flow from the outlet side of the upper layer in the opposite direction, whereas in the lower layer, it is a circulation flow toward the outlet side.

Numeral 8 is provided with a pair of L-shaped plate members 8a and 8b facing each other and sprockets 8c and 8d at the start and end of the plate member, and a conveyor belt 8e made of a wire mesh, and rotated by a motor 8f. The conveyor is configured as described above, and a partition plate 8g is attached to the conveyor belt 8e at appropriate intervals. Incidentally, 8h is a sprocket for guiding the L-shaped bent portion.

Reference numeral 9 denotes a frame body which is installed above the water tank 1, and has a pair of columns 9a at the front and rear positions on the side wall of the water tank 1.
9b, 9c, and 9d are erected, and the L-shaped conveyor 8 can be lifted and lowered to a certain height position by using these columns as guides. 10a and 10b are the hanging chains, and 11a and 11b are The erection chain wheel, 12 is a driving motor. Incidentally, 13 is a control box.

FIG. 3 is a perspective view of a mesh plate 14 used in the present invention, in which a pair of columns 14a, 14b whose upper edges are key-shaped are drawn with respect to the opposed longitudinal edges of the water tank 1. By hanging, the frame 15 is erected at a constant height position on the conveyor 8 arranged on the bottom surface of the water tank. At this time, the mesh intervals of the frame 15 are comb-shaped notches m at regular intervals.
Is provided, and thin rods 16a, 16 are appropriately provided for the notches m.
By inserting b, an arbitrary size can be obtained. The spacing between the eyes can be appropriately changed according to the type and size of the fish, and when it floats in the initial frozen state, it does not pass through the spacing between the eyes, but the thawing progresses and the fish becomes soft. When it takes on a property, it will pass through the interstices and settle down on the conveyor.

The present invention is constructed as described above, and when the present apparatus is used, water is introduced to a certain depth in the tank and the conveyor 8 is settled on the bottom of the tank, and the net plate 15 is placed above it. In addition to arranging, the air is ejected from the air ejection pipe to bring it into an operating state. In this state, the frozen fish is charged from above.

[0012] However, since the frozen fish introduced from above has a specific gravity of ice of 1 or less, even if it is initially settled to some extent, it remains in a floating state on the net plate 15, and it is thawed gradually later. As the settling depth increases as it advances, it passes through the mesh spacing of the mesh plate, and when it reaches the rotating conveyor, it is taken out to the outside.

[0013]

[Effects of the Invention] In the present invention, a net plate is provided at a certain depth below the surface of the water so that the frozen fish initially float, so that the fish is completely thawed above the net plate. Since the floating bag in the built-in part has ruptured, it settles toward the bottom of the tank as the thawing progresses, and finally it passes through the mesh plate with a fixed interval and is taken out sequentially. Therefore, it is possible to efficiently extract and extract thawed fish and unthawed fish even under the flow of water by vigorous air blow. At this time, the grid frame of the mesh plate
Are formed in a large number of comb-shaped notches, and thin rods are formed in the comb-shaped notches.
According to the type and size of the fish
It is possible to easily change the eye-to-eye distance.

That is, a thawed product of stable and uniform quality can be obtained, and the freshness is good and many kinds of frozen fish are obtained.
This will greatly contribute to the rapid improvement in the efficiency of the thawing work.
