Embodiment 1

[0033] Example 1 Fish skin refining separator

[0034] See figure 1 , a fish skin refining separator, which includes: a beating, shearing and rubbing device and an air selection device, the beating, shearing and rubbing device includes: a circular outer cylinder 2, a rotor 3, and the rotor 3 is provided with teeth 31 in a spiral arrangement around it, One end of the circular outer cylinder 2 is provided with a feeding port 1 , and the other opposite end is provided with a discharging port 5 .

[0035] When using, peel off the skin of the freeze-dried fish by hand, or dry or freeze-dry the fresh fish skin divided by hand. The skin is in the circular outer cylinder 2, and under the combined action of the teeth 31 and the partitions or grilles in the circular outer cylinder 2, the fish skin is hammered, sheared, and screwed, and contains 10-15% water. The fish skin has excellent toughness and is not broken, while the fish meat, fish scales and fish bones containing 10-15% water...

Abstract

The invention discloses a fish skin refining and processing method which is characterized in that fish skin is cut off from freeze-dried fish manually or fresh fish skin which is cut off manually is baked or freeze-dried, the water content of the fish skin is 10% to 15%; after being beaten, rubbed and sheared, fish, fish scales, fish bones and the like are crushed and separated from the fish skin and are subjected to winnowing; after being refined, the dry fish skin which has a great amount of pigment removed becomes fluffy, white and soft, so that refined fish skin can be obtained. The invention further provides a fish skin refining separator which comprises a round outer cylinder and a rotor; the rotor is provided with teeth; a baffle plate is arranged on the inner side of the round outer cylinder. The invention has the advantages that the production efficiency is improved, a great amount of manpower is saved, and the manufacturing cost is lowered; meanwhile, high-grade and pure raw materials are provided for production of fish skin collagen, a firm foundation is laid for production of high-grade fish skin collagen, and the bottleneck problem that large-scale and industrialization production can not be carried out can be solved.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and specifically relates to a method for refining fish skin and a refined fish skin powder and slurry for producing collagen. Background technique [0002] Collagen, also known as collagen, is a fibrous protein formed by intertwining three peptide chains. It is a glycoprotein containing a large amount of glycine, proline, hydroxyproline and sugar. Cartilage and tendon and other tissues are the most abundant protein in the body. There are 19 types of collagens that have been found, among which type I collagen, type II collagen and type III collagen are the main components of collagen fibers, which mainly exist in the connective tissue of animals, and play the functions of supporting organs and protecting the body. structural protein. [0003] Collagen contains different types of collagen in various animal tissues. Collagen is synthesized by fibroblasts and exists in human connective tis...
