Vacuum infiltration device and method for pretreatment in animal and plant extraction processes

Abstract

The invention discloses a vacuum infiltration device for pretreatment in an animal and plant extraction processes. The device comprises an infiltrating tank, a liquid storage tank and a vacuum unit, wherein the infiltrating tank is provided with a discharge outlet, a vacuum release port, a feed inlet, a liquid feeding port and a vacuumizing port; the liquid storage tank is connected with the liquid feeding port of the infiltrating tank through a liquid feeding pipe; the vacuum unit is connected with the vacuumizing port of the infiltrating tank through a vacuum pumping pipe; the infiltrating tank is internally provided with a stirring device consisting of a stirring shaft and screw blades which are arranged on the outer wall of the stirring shaft, the diameter of the screw blade is gradually reduced from top to bottom, and the lower end of the screw blade extends to the discharge outlet; and the infiltrating tank is also provided with a slowdown motor which is controlled and connected through an electric appliance control device, an output shaft of the slowdown motor is connected with the stirring shaft in the stirring device through a coupling, and the rotating direction and rotating speed of the stirring device are controlled through the slowdown motor. According to the invention, an effect of infiltration can be achieved and the complete infiltration of an extracted object is realized in a short time, and the multiplication of microbes can be completely eradicated in an infiltration process in a vacuum environment.

Description

technical field [0001] The invention relates to a vacuum infiltration device and method used for pretreatment of animal and plant extraction technology. Background technique [0002] Animal and plant extraction or extraction process is widely used in traditional Chinese medicine, health care products, daily chemicals, natural food additives and other industries. The purpose is to dissolve and separate the active ingredients in natural crops, and then further concentrate and refine them into desired products. The solvent used may be water, alcohol or other organic solvents (hereinafter collectively referred to as solvents). Hereinafter, animal and plant raw materials are collectively referred to as extraction objects. [0003] Extraction process: [0004] 1. The solvent enters the inside of the extraction object and fills the surrounding cells [0005] 2. Solvent molecules penetrate the cell wall and cell membrane into the cell interior [0006] 3. The solvent dissolves ...

AI Technical Summary

Problems solved by technology

Therefore, the first step of extraction is to fully infiltrate the extraction object, that is, the solvent needs to fully penetrate into the intercellular space of the tissue. Inability to fully and efficiently achieve extraction

[0010] In the prior art, there is no special infiltration device. The infiltration method is to contact and soak the extraction object with the solvent for a long time. Although infiltration can be achieved, the disadvantages are:

[0011] 1. If the time is too long (from 30min to 6h), the production efficiency will be reduced;

[0012] 2. Inadequate or insufficient infiltration;

[0013] 3. Microbial growth during infiltration
