Abstract

The invention relates to a charging technology capable of improving yield of CO2 supercritical extraction and belongs to the technical field of supercritical extraction. The charging technology can solve the problems that extraction yield is unstable, the yield is relatively low and raw material waste is enormous as filling is tight and permeability is poor in an extraction technology charging method in the prior art. The charging technology comprises the following steps: taking a plurality of raw materials, putting into a plurality of cloth bags, uniformly placing a plurality of steel wire balls into the cloth bags, sealing, taking eight cloth bags, horizontally paving and placing the eight cloth bags at the bottom of an extraction reaction kettle; additionally taking a plurality of raw materials, and dispersing and placing at an upper layer of the eight cloth bags in the first step; then taking eight cloth bags filled with the raw materials and the steel wire balls, and horizontally paving at the upper layer of the raw materials which are dispersed and placed in the second step; then dispersing and placing a plurality of raw materials on the cloth bags filled with the raw materials and the steel wire balls in the three step; and in the order, sequentially alternately placing the cloth bags filled with the raw materials and the steel wire balls as well as the raw materials until the required production quantity is achieved. The charging technology provided by the invention has the advantages that discharging is stable, yield is high, and processing cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of supercritical extraction, and specifically relates to a method for improving CO 2 The charging process of supercritical extraction yield. Background technique [0002] The existing traditional extraction process charging method is only to put all the raw materials into the feed tank, the material is very tightly packed, and the permeability is poor, which makes the extraction yield unstable and low, and the waste of raw materials is large. Therefore, the existing traditional extraction process charging method is neither practical nor practical, and cannot meet the requirements for efficient extraction of effective substances. Contents of the invention [0003] In order to solve the problems in the prior art that the charging method of the extraction process is tightly packed and poor in permeability, the extraction yield is unstable and low, and the waste of raw materials is large, the present inventio...
