Problems solved by technology

[0004] The object of the present invention is to provide a grading and precooling device for pelagic fish catches and its application. The device can not only improve the precooling efficiency of the fish catches, but also can be well connected with other operations in the preservation process of the pelagic fish catches. Improve the integrity and automation of the fresh-keeping system; solve the problems that the fish cannot be pre-cooled quickly after fishing, and the pre-cooling effect is not good.

Embodiment 1

[0037] Example 1. Classification and pre-cooling device for deep-sea fishes

[0038] refer to figure 1 , figure 2 and image 3 , the classification pre-cooling device for ocean catches includes a pre-cooling chamber 5 with thermal insulation performance, a fluid state ice making device 1, an electronic control module 11, a first conveyor belt 12 and a second conveyor belt 13; the fluid state The ice-making equipment 1 is connected to the pre-cooling chamber 5 through a fluid ice output pipeline 3; the first conveyor belt 12 and the second conveyor belt 13 are symmetrically arranged on both sides of the outer wall of the pre-cooling chamber 5, and are used for framing the fish. The goods are transported into and out of the pre-cooling cabin; the electronic control module 11 is arranged on the outer wall of the cabin to control the overall operation of the pre-cooling process.

[0039] The pre-cooling compartment 5 is provided with a partition 6, and the compartment is divid...

Embodiment 2

[0044] Example 2. Application of deep-sea catch classification and pre-cooling device

[0045] Adopt the classification precooling device of the deep-sea fishes described in Example 1:

[0046] 1) Start the fluid ice preparation equipment 1, and extract the seawater to prepare fluid ice with an ice content of 30% to 40% and a temperature of -2.3°C to -2.5°C. The fluid ice enters the compartment of the pre-cooling compartment through the fluid ice output pipeline 3;

[0047] 2) After the catch is caught on the deck, the catch after grading and framing is conveyed through the first conveyor belt 12 to the bottom of the first circulation assembly 7 away from one end of the fluid ice making equipment;

[0048] 3) The first circulation component 7 transfers the framed fish to the first pre-cooling compartment for pre-cooling, and the subsequent framed fish are stacked, and the stacking height does not exceed 2 / 3 of the cabin height;

[0049] 4) When the pre-cooling of the framed ...

Abstract

The invention discloses a classification and pre-cooling device for pelagic fish catches and an application thereof. The grading and pre-cooling device for pelagic fish includes a pre-cooling chamber with thermal insulation performance and a fluid ice making equipment; The extraction equipment is connected to the pre-cooling cabin through the flow ice output pipeline; the two ends of the pre-cooling cabin are respectively provided with circulation components for the transport of fish catches, and the cabin is divided into a plurality of compartments by partitions, and each compartment is divided into several compartments. The bottom of each compartment is provided with a transmission device; the fluid ice making equipment transports fluid ice to each compartment of the pre-cooling chamber through the fluid ice output pipeline; the present invention performs overall control through the electronic control module, The rapid cooling of the fish body is achieved by grading pre-cooling in different compartments of the cabin. The grading pre-cooling in different compartments can effectively shorten the pre-cooling time by 1 / 3, and improve the overall quality of deep-sea fishing. Freshness efficiency. In addition, the catches in the cabin are stacked and pre-cooled, which avoids squeezing and damage between the fish bodies and ensures the quality of the fish bodies.

Description

(1) Technical field [0001] The invention relates to a classification and precooling device for deep-sea fish and its application. (2) Background technology [0002] In recent years, due to the continuous improvement of people's income level, the expenditure on the purchase of seafood has also continued to increase, so that the seafood industry has maintained steady growth for many years. The increase in demand has led to the emergence of market competition, and people's quality requirements for seafood are also increasing. higher. For some catches that need to be fished at sea, if there is no good preservation measures after fishing, their freshness will be greatly affected, and they will be in a disadvantageous position in the market competition of seafood sales. [0003] The fresh-keeping method of deep-sea fishing catches mainly adopts the method of frozen storage, but the direct freezing and storage of catches cannot make the fish body cool down rapidly in a short time,...
