Device and method suitable for preserving king crabs in equipment type marine ranch

Abstract

The invention relates to the field of marine aquatic product preservation, in particular to a king crab preservation device and method suitable for an equipment type marine ranch, and the king crab preservation device comprises a workbench, a preservation cage, a fixing piece, a lifting piece and a connecting piece. The connecting piece connects the storage cage and the fixing piece; after the lifting piece drives the storage cage to descend into water through the connecting piece, the connecting piece is in a hard state, and in the process that the lifting piece drives the storage cage to ascend above the water surface, the connecting piece is in a flexible state. When the connecting pieces are in the hard state, the probability that the connecting pieces of the adjacent storage cages are intertwined in water can be reduced, mutual collision between the storage cages is reduced, and the survival rate of king crabs is increased; when the connecting pieces are in the flexible state, the connecting pieces located above the workbench can be bent and deformed, and therefore the connecting pieces can be arranged and collected conveniently.

Description

technical field [0001] The invention relates to the field of preservation of marine aquatic products, in particular to a device and method for preserving king crabs suitable for equipment-type ocean pastures. Background technique [0002] King crabs belong to crustaceans and are mainly distributed in cold seas, where the water temperature is 2-5°C. Due to its huge size, delicious meat and rich nutrition, domestic consumption has grown rapidly in recent years. The main sources of fresh king crabs in my country are the United States, Russia, Norway and other countries. Domestic fresh suppliers mainly adopt indoor running water or circulating water to temporarily store king crabs. Environmental conditions such as water temperature, oxygen content, and water flow speed need to be controlled. , the general storage period is 5-7 days. During the storage process, king crabs will die, become thinner, and their vitality will become weaker, which will affect the sales price of king cr...

Problems solved by technology

The main sources of fresh king crabs in my country are the United States, Russia, Norway and other countries. Domestic fresh suppliers mainly adopt indoor running water or circulating water to store king crabs for temporary storage. Environmental conditions such as water temperature, oxygen content, and water flow speed need to be controlled. , the general storage period is 5-7 days. During the storage process, king crabs will die, become thinner, and their vitality will become weaker, which will affect the sales price of king crabs. high

In addition, in order to ensure the fullness of king crabs, it is necessary to perform work such as feeding, regular pond cleaning, and pouring, which is labor-intensive and cumbersome.
