Equipment for extracting polypeptides in sea cucumbers in East China Sea

Abstract

The invention relates to the technical field of polypeptide extraction accessory devices, and in particular relates to equipment for extracting polypeptides in sea cucumbers in the East China Sea. Theequipment comprises a hollow stirring kettle, a first threaded rod and a second threaded rod; a first bearing is arranged in the central area of the top of the stirring kettle; the inner ring of thefirst bearing is connected with a first stirring shaft; multiple first stirring blades are arranged on the outer side wall of the first stirring shaft; the interior of the first stirring shaft is hollow; a mechanical seal is arranged at the bottom in the first stirring shaft; a second bearing is arranged on the top in the first stirring shaft; a second stirring shaft is arranged on the inner ringof the second bearing; the second stirring shaft is rotatably connected with the mechanical seal; multiple second stirring blades (34) are arranged in the lower half area of the second stirring shaft;and a first bevel gear is arranged on the first stirring shaft. The equipment in the invention is simple in structure; the mixing effect and the mixing speed of a freeze-drying protective agent and semi-finished polypeptide concentrated solution are improved; the polypeptide concentrated solution and the freeze-drying protective agent on the inner wall are convenient to clean; and the product quality is improved.

Description

technical field [0001] The present invention relates to the technical field of polypeptide extraction accessory devices, in particular to an extraction equipment of Donghai black ginseng polypeptide. Background technique [0002] Pure natural deep-sea black cucumber is full of treasures. The meat wall is very nutritious, rich in collagen, arginine, DHA, acidic mucopolysaccharides, chondroitin sulfate and other nutrients. Sea cucumber peptides can improve anemia, supplement nutrition, and delay aging , Improving immunity and other health effects, it is helpful for heart failure, high blood pressure, bronchitis, hyperhidrosis, cough, etc. [0003] During the extraction process of black ginseng polypeptide, the semi-finished polypeptide concentrate needs to be cooled and dried by freezing. In order to prevent the cytokines and natural peptides in the concentrated marine biological polypeptide from being damaged during the freezing process, it is generally necessary to remove T...

AI Technical Summary

Problems solved by technology

[0003] During the extraction process of black ginseng polypeptide, the semi-finished polypeptide concentrate needs to be cooled and dried by freezing. In order to prevent the cytokines and natural peptides in the concentrated marine biological polypeptide from being damaged during the freezing process, it is generally necessary to remove The lyoprotectant is added to the semi-finished polypeptide concentrated solution. Since the semi-finished polypeptide concentrated solution is relatively viscous, there will be insufficient mixing of the powdered lyoprotectant and the semi-finished polypeptide concentrated solution, resulting in cytokines and natural substances in the polypeptide after lyophilization. The polypeptide is damaged, resulting in poor quality of the concentrated polypeptide concentrate, and the phenomenon of sticking to the wall will occur during the stirring process, which will affect the quality of the product
