Problems solved by technology

[0004] The purpose of the present invention is to overcome the risk of swimming crabs freezing on the surface of swimming crabs in the process of quick-freezing swimming crabs in the aquatic product quick-freezing equipment in the prior art, to provide a kind of swimming crabs that can be continuously quick-frozen, and can effectively solve the problem that swimming crabs are frozen on the surface of the freezing equipment. During the quick freezing process, the water on the surface of swimming crabs and the conveyor belt freeze, which causes the swimming crabs to freeze on the surface of the freezing equipment. The freezing equipment for maintaining the quality of fresh swimming crabs

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] like figure 1 Shown, a kind of freezing equipment that keeps fresh Portunus crab meat quality comprises freezer chamber 1, belt conveying mechanism and auxiliary anti-freezing device 12. The belt transmission mechanism includes a frame, five transfer conveyor belts 9a, 9b, 9c, 9d, 9e arranged side by side in the first, second, third, fourth and fifth, and several active conveyor belts corresponding to each transfer conveyor belt one by one. Wheel 3a and driven wheel 3b. Each transfer conveyor belt is wound on the corresponding driving wheel and driven wheel. Each transfer conveyor belt constitutes a complete conveyor belt 9 for transmitting swimming crabs together. Each transfer belt passes through the freezer. The freezer is a liquid nitrogen freezer. The top of the conveyor belt is provided with two left and right vertical guards 1...

Abstract

The invention discloses freezing equipment for keeping fresh meat quality of swimming crabs, aiming at providing freezing equipment for keeping fresh meat quality of swimming crabs, which can be used for continuously quick-freezing swimming crabs and can be used for effectively solving the problem that the swimming crabs are frozen on the surface of refrigerating equipment in the case that water on the surfaces of the swimming crabs is frozen on a conveying belt in the process of quick-freezing the swimming crabs. The freezing equipment comprises a refrigerating chamber and a belt conveying mechanism, wherein the belt conveying mechanism comprises a conveying belt for conveying swimming crabs; the conveying belt is composed of a plurality of driven conveying belts which are arranged side by side; the various driven conveying belts run through the refrigerating chamber; and in the working process of the conveying belt, the conveying speed of one of any two adjacent driven conveying belts is more than or less than the conveying speed of another driven conveying belt.

Description

technical field [0001] The invention relates to a freezing device, in particular to a freezing device for maintaining the quality of fresh swimming crab meat. Background technique [0002] Aquatic product freezing refers to the use of low temperature conditions to inhibit the activity of autolyzed enzymes and the reproduction of attached microorganisms in aquatic products, and to slow down the chemical reactions such as lipid oxidation and non-enzymatic browning, so that they can maintain good quality during storage. Low temperature preservation method. The freezing of aquatic products generally includes two types of methods: refrigeration preservation and freezing preservation. Among them, the freezing preservation method mainly uses freezing equipment to quickly freeze fresh aquatic products. Quick freezing of fresh aquatic products (such as swimming crab quick freezing) can quickly freeze the product, pass through the ice crystal formation zone, prevent the formation of ...
