Description

Squid air supporting rinsing device

Technical Field

The invention relates to aquatic product processing equipment, in particular to a squid air floatation rinsing device.

Background

The squid is rich in nutrition, high in protein and low in fat, is rich in protein and various amino acids required by a human body, has essential amino acid composition close to that of whole egg protein, contains rich calcium, phosphorus and iron elements, is beneficial to bone development and hematopoiesis, and can prevent anemia, meanwhile, the body part of the squid accounts for about 50% of the body weight, the head part and the foot part of the squid account for about 30% of the body weight, so that the edible part of the squid reaches over 80% and is about 20% higher than that of common fishes, and the squid is a good raw material for processing aquatic products. The squid ball is a new squid product and has important significance for improving the economic value of the squid.

The main process flow of the squid ball is as follows: cleaning → rinsing → mixing by chopping → molding → heating → cooling → quick-freezing → packaging, wherein rinsing is an important link of squid ball processing, has a great influence on the quality of squid balls, and has two main purposes: firstly, removing blood, fat and water-soluble protein to improve the color, smell and tissue characteristics of the squid surimi; and secondly, myofibrillar protein is concentrated to improve the concentration of the myofibrillar protein, so that the squid surimi has higher gel forming capability and the taste of the squid balls is improved.

Adopt the rinsing device to carry out the rinsing to the squid at present usually, for example, grant bulletin number CN207854932U, grant bulletin day 2018.09.14's chinese patent discloses a rinsing device after fish processing, including rinsing device body, filter frame and filter screen, the inside evenly distributed of rinsing device body has the spout, the bilateral symmetry of filter screen is provided with the fixed plate, and the fixed plate all through the bottom one side joint of gag lever post and filter frame, all weld on the gag lever post has the limiting plate, and one side of limiting plate all through reset spring and filter frame elastic connection. The rinsing device has the following defects: (1) dirt such as blood foam, fat and the like generated in the rinsing process floats on the water surface and cannot be removed, and can be adhered to the squid meat again, so that the rinsing effect is poor; (2) the water flows out from the nozzle and flows upwards through the water suction pump in the pumping rinsing device body, the fishes on the filter screen are rinsed through the surging of the water flow, the water flow sprayed out from the nozzle is in a linear shape (laminar flow), the fish meat and the water cannot be fully exchanged, the dissolution speed of components such as unnecessary water-soluble protein and pigment in the fish meat is low, and the rinsing time is long; (3) the flowing water flow hardly enters the inner (central region) fish meat in the strainer, resulting in poor rinsing effect (poor rinsing uniformity).
