Embodiment 1

[0034] Embodiment 1, offshore fish catch preservation system

[0035] refer to figure 1 and figure 2 , the fresh-keeping system for offshore catches includes a fresh-keeping cabin, a slurried ice making device 13, and a conveyor belt 16; wherein, the fresh-keeping cabin is a double-layer composite structure with thermal insulation performance; 14 links to each other with fresh-keeping cabin, and conveyer belt 16 is used for transshipment catch and enters and exits in the fresh-keeping cabin.

[0036] The fresh-keeping cabin is composed of a cabin body 1 and a cover plate 2; the side of the cover plate 2 facing the cabin body is provided with a circulation assembly 4 fixed by slide rails, and the circulation assembly 4 is used for transshipment of framed catches Operate and place outside the cabin when the cabin is closed; the cover plate 2 is provided with sealing strips around the contact with the cabin body 1, which can make the cabin body reach a better sealing effect wh...

Embodiment 2

[0040] Embodiment 2, the application of offshore fish catch preservation system

[0041] When carrying out fishing operations, start the liquid ice production equipment 13, extract seawater to produce liquid ice with an ice content of 30% to 40%, and a temperature of -2.3°C to -2.5°C, and lead to the fresh-keeping compartment, the electronic control module 12 Control the lifting device 3 to lift the upper cover plate 2 to the maximum height. The fish catches are put into the fish frame with holes and placed on the conveyor belt 16 in turn, and are sequentially transferred to the lower end of the circulation assembly 4 under the control of the electronic control module 12, and the circulation assembly 4 transfers the framed fish catches under the control of the electric control module 12 The 5 fish frame fixed partitions in the fresh-keeping cabin are fixedly stacked. After the fishing operation is over, when the fluid ice is submerged in the upper layer of catches, the product...

Abstract

The invention discloses a fresh-keeping system for offshore catches and application of the fresh-keeping system. The fresh-keeping system for the offshore catches comprises a fresh-keeping cabin with a heat preservation performance and a double-layer composite structure, ice slurry preparation equipment and a conveying belt, wherein the ice slurry preparation equipment is connected to the fresh-keeping cabin through an ice slurry output pipeline, and the conveying belt is fixed on the outer side wall of the fresh-keeping cabin and is used for moving the catches into and out of the fresh-keeping cabin. According to the fresh-keeping system for the offshore catches and the application of the fresh-keeping system, overall control is carried out through an electric control module, preparation of ice slurry in the fresh-keeping cabin and movement of the framed catches are carried out at the same time, the requirement of continuous operation is met, a fish frame partition plate is arranged in the cabin so that the catches entering the cabin can be fixed, subsequent stacking of frame bodies can be stabilized, compared with a mode that the catches are directly placed in the cabin body for ice slurry preservation, the framed catches are convenient to load and unload, extrusion damage among fish bodies is avoided, the quality of the fish bodies is guaranteed, an ice slurry circulating device is arranged in the cabin body, the phenomenon of uneven temperature distribution caused by ice crystal gathering and floating after long-time standing is avoided, and the preservation effect is improved.

Description

(1) Technical field [0001] The invention relates to a fresh-keeping system and application of offshore fish catches. (2) Background technology [0002] Seafood is far away from the crowd, rarely polluted, and rich in nutrition, which brings many benefits to human health. Therefore, people's demand for seafood is increasing year by year. Due to the increase in market demand, the requirement for the freshness of seafood is also getting higher and higher. How to maintain the freshness of the fish catch after fishing has become a research hotspot. [0003] The traditional fresh-keeping methods in China mainly use flake ice or solid ice for fresh-keeping. The cooling speed is slow and the degree of automation is low, which cannot achieve a good fresh-keeping effect. In recent years, with the development of fresh-keeping technology, fresh-keeping of seawater fluid ice has been widely promoted. Although the fresh-keeping effect has been greatly improved compared with flake ice and...
