A classification precooling device for deep-sea fish and its application

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,...

AI Technical Summary

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.
