Multistage separation device for animal and plant raw materials as well as method and application thereof

Abstract

The invention discloses a multistage separation device for animal and plant raw materials as well as a method and an application thereof, and belongs to the technical field of plant extraction. The multistage separation device comprises separating devices and a pulverizer (3), wherein each separating device comprises a leaching tank (1) and a solid-liquid separator (2); the leaching tank (1) is connected with the pulverizer (3) by virtue of a raw material conveying pipe (101); a discharge port of the leaching tank (1) is connected with a feed port pipeline of the solid-liquid separator (2) by virtue of a pump (4); a separated liquid outlet of the solid-liquid separator (2) is connected with a separated liquid output pipe (201); a solid material outlet of the solid-liquid separator (2) is connected with a first conveyor (5); a plurality of the separating device are arranged on the multistage separation device in a multistage mode from top to bottom along a solid material conveying direction. The multistage separation device for the animal and plant raw materials can pulverize the raw materials into powder for solid-liquid separation extraction, is high in extraction efficiency and yield, and can obviously increase the concentration of the obtained separated liquid, reduce the use level of a solvent, and reduce the production cost.

Description

technical field [0001] A multistage separation device for animal and plant raw materials and its method and application belong to the technical field of animal and plant extraction. Background technique [0002] Extraction of animal and plant raw materials refers to the use of appropriate solvents or methods to extract and process active ingredients (the active ingredients can be dissolved in solvents) from animal and plant raw materials (all or a certain part). In the existing large-scale industrial production, the extraction method of active ingredients in animal and plant raw materials is mostly to dry the animal and plant raw materials and press them to obtain flake raw materials, spray the flake raw materials with solvents to obtain extracts, and then separate and refine them. (eg extraction, distillation). [0003] The applicant found in the research that the existing extraction device has the following problems: firstly, the yield of the active ingredient in the exis...

AI Technical Summary

Problems solved by technology

[0003] The applicant found in the research that the existing extraction device has the following problems: firstly, the yield of the active ingredient in the existing extraction device is low, the extraction efficiency is low, and the active ingredient in the plant is difficult to leach into the solvent in the way of tableting, Moreover, it is difficult to fully extract the solvent by spraying, and the extraction efficiency of the obtained active ingredients is low

Secondly, although the existing extraction device adopts solid-liquid separation technology, it does not help how to improve the yield of active ingredients.

Again, the applicant found that the concentration of the separation liquid obtained by the existing extraction device is low and the volume is large, which not only increases the cost of the solvent, but also increases the subsequent energy consumption for refining and concentrating the separation liquid
