Problems solved by technology

[0004] At present, in the traditional surimi production process, the water-soluble protein and blood water in the fish pulp are mainly removed by static rinsing. Generally, multi-channel dehydration procedures are required, and more water is used; moreover, there are many existing production links, which take a long time, and the processing process is mostly intermittent operation, and the key steps need to be adjusted manually. In addition, the last dehydration step generally adopts screw extrusion The method, the physical friction caused by the processing precision of the equipment can easily cause serious physical damage to the fish meat tissue, and the heat generated by friction can easily lead to the denaturation of the salt-soluble protein in the fish meat, which will have a negative impact on the quality of the surimi

Abstract

The invention discloses a continuous minced fillet production system and a method for preparing minced fillets, and belongs to the field of minced fillet processing. The system comprises a fish meat separation machine, a first horizontal screw settling centrifuge, a continuous soaking pond, a rotary screen, a first built-in spray head rotary screen, a second horizontal screw settling centrifuge and post-treatment equipment. Through horizontal screw settling centrifuging, quick solid-liquid separation of a minced fillet aqueous solution is realized, and moisture removal is more thorough; and the centrifuge is used for performing solid-liquid separation, the continuous soaking pond is used for performing oil-water separation, and the built-in spray head rotary screen is used for performing adehydrating process and a rinsing process, so that serialization task of a minced fillet production flow is realized. Compared with a traditional production line, the continuous minced fillet production system disclosed by the invention does not need a link of extruding for dehydrating, so that the quality of the minced fillets can be improved, and protein denaturation in a processing course is reduced.

Description

technical field [0001] The invention relates to a continuous surimi production system and a method for preparing surimi, belonging to the field of surimi processing. Background technique [0002] As quick-frozen surimi products are more and more popular among consumers, the demand for frozen surimi is also increasing. However, with the continuous development and utilization of marine fish resources and the limitation of the total amount of domestic freshwater fish farming, the total fish resources that can be used for surimi processing are showing a downward trend. At present, the silver carp surimi processing technology has been able to achieve a surimi yield of about 36%, but due to the multiple extrusion and rehydration processes in the processing process, the quality of the surimi is seriously deteriorated, and the production process consumes a lot of water. [0003] In addition, as my country has continued to promote the environmental protection policy of "prevention f...
