Problems solved by technology

The other is the air-cooling process. The aquatic products are cooled under the blowing of the cooling fan through the freezing chamber. However, due to the slow heat conduction process, a long freezing channel is required and the production efficiency is low. Although compared with the liquid nitrogen freezing process Costs have come down, but remain high

Abstract

The invention discloses a saltwater spraying and quick-freezing device. The saltwater spraying and quick-freezing device comprises combined freezing of a saltwater spraying and pre-freezing device anda wind cooing and freezing device. Compared with the prior art, the saltwater spraying and quick-freezing device can quick freeze boxed shrimps, and has the advantages of being high in productivity,energy-saving, good in quality of frozen products, free from running off of moisture of the frozen products and the like.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing equipment, in particular to a salt water spray quick-freezing device. 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. At present, there are mainly two kinds of freezing preservation methods for aquatic products. One is the liquid nitrogen freezing process, which usually uses liquid nitrogen to be directly sprayed on the aquatic products (fish body) to achieve the purpose of rapid freezing of aquatic products. Because it can freeze the product quickly, pass through the ice crystal formation zone, prevent the formation of human ice c...
