Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thawing machine for efficiently thawing frozen fish.

[0002]

[Prior art]

 Conventionally, frozen fish are thawed by putting them in a water tank and removing them after a certain period of time while stirring the water flow.

[0003]

[Problems to be solved by the device]

 There is a problem that the thawed and unthawed items are mixed in the above take-out work, and if you take a lot of time to solve this, the freshness of the already thawed items will decrease. It becomes a problem. SUMMARY OF THE INVENTION The present invention solves the above problems and provides a device for efficiently extracting thawed products in sequence.

[0004]

[Means for Solving the Problems]

 According to the present invention, a fusible pipe having a large number of air ejection holes is laid on the bottom of a rectangular parallelepiped water tank, and one end to the other end in the longitudinal direction of the bottom of the tank is slightly above the fumarole. A conveyor having an L-shaped carrier belt is rotatably arranged toward the conveyor belt, and a mesh plate having an appropriate size interval can be attached and detached at a position in the tank above a certain height of the conveyor. It is characterized by being provided.

[0005]

[Action]

 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 interval, is received by the conveyor that rotates at the bottom of the tank, and is taken out to the outside. Will be done.

[0006]

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, on the bottom of which a large number of air ejection holes 2 are formed and fumarole pipes 3 are laid, and air is ejected by the operation of a drive pump provided in a driving chamber 4. It is supposed to be done.

Reference numeral 5 is an overflow slit formed in the upper side wall of the water tank, and an air ejection 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, the 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 to the outlet side of the lower layer.

Numeral 8 is 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 members, and a conveyor belt 8e made of wire mesh is installed and rotated by a motor 8f. The conveyor is designed to be moved, and a partition plate 8g is attached to the conveyor belt 8e at an appropriate interval position. Incidentally, 8h is a sprocket for guiding the L-shaped bent portion.

Reference numeral 9 is a frame that is installed above the water tank 1, and a pair of columns 9a, 9b and 9c, 9d are erected at the front and rear positions on the side wall of the water tank 1, and these columns are used as guides for the above-mentioned operations. The L-shaped conveyor 8 can be moved up and down to a fixed height position. 10a and 10b are chains for hanging the same, 11a and 11b are chain wheels for the same installation, and 12 is a motor for driving the same. 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 facing longitudinal edges of the water tank 1. By hanging it, the box frame 15 is erected at a constant height position on the conveyor 8 arranged on the bottom surface of the water tank, and at this time, the box intervals of the box frame 15 are comb-shaped at regular intervals. By providing the notch m and appropriately inserting the thin rods 16a and 16b into the notch m, an arbitrary size can be obtained. The distance between the eyes is appropriately changed according to the type and size of the fish. When floating in the initial frozen state, it does not pass through the distance between the eyes, but the thawing progresses and the fish becomes soft. When it becomes sexual, it will pass through the gaps and settle down on the conveyor.

The present invention is constructed as described above, and when the apparatus is used, water is introduced to a certain depth in the tank, the conveyor 8 is allowed to settle on the bottom of the tank, and the mesh plate 15 is placed above the bottom. In addition to arranging the above, 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.

However, since the frozen fish introduced from above have a specific gravity of ice of 1 or less, even if the frozen fish settle to a certain degree at the beginning, they are in a floating state on the net plate 15, and gradually later. As the thawing progresses, the sedimentation depth increases, passes through the mesh spacing of the mesh plate, and when it reaches the rotating conveyor, it is taken out to the outside.

[0013]

[Effect of device]

 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 it ruptured, it settled toward the bottom of the tank as thawing proceeded, and finally it passed through a mesh plate with a fixed size interval and was sequentially taken out. It is possible to efficiently extract thawed fish and unthawed fish while extracting water even with a vigorous air blow.

That is, a thawed product of stable and uniform quality can be obtained, and the freshness is good and it contributes to the improvement of the efficiency of the thawing work.
