Cyclic salting-out dropwise adding device based on collagen extraction

Abstract

The invention provides a cyclic salting-out dropwise adding device based on collagen extraction, and relates to the technical field of collagen extraction. The device solves the problems that during collagen extraction salting-out dropwise adding, the viscosity of collagen is relatively high, and NaCl cannot be quickly and uniformly dispersed after being added into collagen solution, so that the collagen is not uniformly separated out, and part of undissolved NaCl is wrapped during precipitation, so that the collagen extraction effect is poor. The cyclic salting-out dropwise adding device based on collagen extraction comprises a salting-out tank, and a circulating pipeline communicated with an inner cavity of the salting-out tank is mounted at the bottom of the salting-out tank. As air flow diffuses and escapes from a micropore part of a fourth aeration pipe in the form of bubbles to stir sediments on the bottom surface of the inner cavity of the salting-out tank, solution in the stirring state is pumped into a circulating pipeline from a discharge pipe through a sine pump, and then is input into the salting-out tank again from a part communicated with the salting-out tank, so that the circulation of the solution in the salting-out tank is realized, and the uniform mixing efficiency of the dropwise added solution in the salting-out tank is further improved.

Description

technical field [0001] The invention belongs to the technical field of collagen extraction, and more specifically relates to a salting-out dripping device based on collagen extraction cycle. Background technique [0002] Proprotein is an important functional substance that constitutes the animal body. It has unparalleled biocompatibility with other synthetic polymer materials. Therefore, as a biological material, it is increasingly important in industries such as medicine, food, and cosmetics. [0003] Collagen extraction processes are mainly divided into three types: acid method, alkaline method and enzymatic method. These three extraction methods all involve a salting-out step. The conventional practice is to add NaCl to the collagen solution to precipitate the collagen. [0004] For example, application number: 201310320162.9 The present invention discloses a special device for extracting type II collagen, the main component of natural cartilage matrix, including a therm...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a cyclic salting-out dripping device based on collagen extraction, to solve the problem of collagen extraction and salting-out dripping, due to the relatively high viscosity of collagen, NaCl cannot be quickly and uniformly dispersed after being added to the collagen solution Open, resulting in uneven precipitation of collagen, and at the same time, it will wrap part of the undissolved NaCl, resulting in poor collagen extraction effect
