Abstract

PURPOSE:To make possible uniform cooling and automation without damage and deformation by own weight, by providing a mechanism for suspending a fish to be frozen and holding partially a portion of the body weight thereof so as not to apply the whole body weight to the hoisting part of the fish body. CONSTITUTION:A fish to be frozen 1 is lifted to a hook 3 with a rope 2, and the hook 3 is fixed on a support plate 4. A wire 6 is fixed on the support plate 4 and ceiling 7 at both ends thereof. A round bar 9 is provided at the lower end of a holding tool 8 to support the mouth of the fish to be frozen 1, and the other end faces the support plate 4 through a spring 5 with a wire 6 passing through a hole 10. Therefore, the spring 5 expands and contracts by adjusting the length of the rope 2, and the distribution of the body weight of the fish to be frozen 1 applied to the rope 2 and the weight thereof received by the round bar 9 can be optionally adjusted.

Description

[Detailed Description of the Invention] Conventionally, large and high-grade fish such as tuna were frozen using suspension methods, or
This was done by air-cooling and freezing on shelves. However, with the conventional hanging method, the tuna skeleton cannot withstand its own weight, causing internal damage and deformation, which reduces the product value. There are disadvantages such as deterioration in quality due to the weight of the parts, and large deformation due to the weight unless the orientation is changed during freezing, making automation difficult. The present invention
This was done to solve these drawbacks.

In the present invention, basically the fish to be frozen is suspended,
Part of the weight of the fish is supported from below, which prevents damage and deformation due to its own weight, and also maintains the advantages of the suspension system, such as uniform cooling and ease of automation.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 is a configuration diagram showing one embodiment, in which a frozen fish l is hoisted onto a hook 3 with a rope 2 tied to its tail, the hook 3 is fixed to a support plate 4, and a wire 6 is connected to the support plate 4 and the ceiling. 7 is fixed at both ends.

Further, a round bar 9 is provided at the lower end of the holder 8 to hold the fish to be frozen.
The other end faces the support plate 4 via the spring 5, and the wire 6 passes through the through hole 10. Therefore, by adjusting the length of the rope 2 appropriately, the suspension ring 5 expands and contracts to arbitrarily adjust the distribution of the weight of the fish hanging on the rope 2 and the weight of the fish received by the round bar 9.

Since the present invention is constructed as described above, it paves the way to a suspended freezing system that can achieve uniform cooling and automation without worrying about damage or deformation due to its own weight, improving onboard labor, saving labor, and improving quality. The industrial value that it contributes to is enormous.

Further, in order to prevent frozen fish from being damaged by the rocking of the boat, it is even better if a part of the holder is provided with a metal fitting to guard the fish.
