Fish preservation method using thermal insulation tanks filled with ice slurry

Abstract

The present invention provides a novel method for fish preservation, which uses thermal insulation tanks filled with ice slurry for preservation of caught fish cargo and is a preservation method replacing a method using ice cubes. A fishing boat using the present preservation method is different from a traditional fishing boat taking along with ice cubes, and takes along with a set of ice slurry preparation equipment and thermal insulation tanks on the boat. The ice slurry production amount is determined according to the yield of fish cargo. The ice slurry is delivered to the thermal insulation tanks in a fish cabin by an ice slurry pump through pipelines. Each used incubator thermal insulation tank is a specific double layer plastic box on the market and has a sealing lid and a water port arranged in a side face and adjacent to the bottom. During operation, steps include sending ice slurry into the thermal insulation tanks at first, then placing the caught fish cargo in the thermal insulation tanks, covering the fish cargo with plenty of ice slurry, closing the sealing lid and arranging the thermal insulation tanks layer by layer in the fish cabin. The present invention achieves preservation by the method using the thermal insulation tanks filled with ice slurry.

Description

technical field [0001] The present invention is a brand-new fresh-keeping method for fish goods, which adopts the mode of incubator + ice slurry to keep fresh-keeping fish goods caught. It is a brand-new fish preservation method that replaces block ice. [0002] The invention belongs to the field of agriculture, forestry, animal husbandry and fishery. Background technique [0003] At present, the chilled fish in the domestic market are basically caught by fishing boats operating in the offshore. Fishing goods are wrapped, so as to play a fresh-keeping effect. [0004] Because the fishing boats in my country's offshore fishing operations are generally small in size, and the block ice production equipment has a large volume and a large power load, this limits the configuration of such block ice production equipment on small fishing boats in offshore fishing operations. Before going to sea, the fishing boats store the chunks of crushed ice in the fish cabin, and carry their o...

Problems solved by technology

[0005] During the fresh-keeping process of fishery products, the blocky crushed ice cannot completely contact the fish body. Even if a small part of the crushed ice is in complete contact with the fish body, as the crushed ice gradually melts, the block ice will separate from the fish body, forming Cavity, unsatisfactory fresh-keeping effect

As a result, some fish products can only be used as raw materials for fishmeal production due to poor preservation, which seriously wastes offshore marine biological resources.

[0006] Especially for high-quality fish products, the freshness of the fish is greatly reduced by the use of block ice. Not only can they not be sold at a good price, but also a waste of high-quality and high-value-added seafood
