Embodiment 1

[0037] Take 4 tons of fresh high-temperature traditional Chinese medicine extracts produced. The high-temperature traditional Chinese medicine extracts are reduced from 100 degrees Celsius to 65-70 degrees Celsius through a plate heat exchanger, and the pH is neutral. Concentration, dialysis water removal at 200L / Hr, the total solid content of the feed Chinese medicine extract is 2-3%, the working time is 10 hours, the total amount of dialysis water removal is 2 tons, using organic thin-layer composite tubular membrane, components The area is 2.6m 2 , The molecular weight cut off is 50MWCO.

[0038] concentrate

[0039] Start at 65-70 degrees Celsius, the component inlet pressure is 3.0-4.0MPa, and concentrate. The concentration ratio is 2-3 times, and the final concentrated liquid volume is 2 tons. The effective ingredient retention rate of ephedrine hydrochloride and mongoside in Biyankang extract is greater than 90%; the retention rate of solid matter is greater than 90%...

Embodiment 2

[0041]Take 160 tons of fresh high-temperature traditional Chinese medicine extract produced, keep the temperature at 65-70 degrees Celsius, and the pH is neutral, pass through the bag-type microfiltration filter, concentrate in the tubular membrane equipment, dialysis to remove water at 5000L / Hr, feed The total solid content of the traditional Chinese medicine extract is 2-3%, the working time is 16 hours, the total amount of water removal by dialysis is 80 tons, and the organic thin-layer composite tubular membrane is used, and the module area is 2.6m 2 , The molecular weight cut off is 50MWCO.

Abstract

The invention relates to a Chinese medicine extract concentrated film device comprising a material inlet pipe, wherein one end of the material inlet pipe is provided with a material inlet, and the other end is connected with a booster pump; the booster pump is connected with a tubular membrane set through a pipeline; the tubular membrane set comprises an outer pipe and a tubular film core arrangedin the outer pipe; the tubular film core is connected with one end of a return pipeline; and the outer pipe is connected with a discharge pipeline. The device can be widely used in the Chinese medicine extract after being simply processed by a 10-micrometer filter and carry out the concentration below 70 DEG C. The device has the advantages of low cost, high concentration capability and efficiency, easy washing and high temperature resistance.

Description

technical field [0001] The invention relates to a device for separating liquid by using a semi-permeable filter membrane, in particular to a device for concentrating a traditional Chinese medicine extraction liquid with a membrane. Background technique [0002] Chinese medicine extracts contain a lot of water. When making Chinese medicine preparations, it is necessary to concentrate the Chinese medicine extracts to separate the active ingredients. The traditional method of concentrating traditional Chinese medicine extracts generally uses a decompression evaporator to directly concentrate by evaporating the water in the Chinese medicine extracts. However, this method consumes a lot of energy and greatly damages the active ingredients of the product, which is not suitable for the current development direction. [0003] The traditional coiled membrane can also be used to separate solvents and solutes, but it is not resistant to pollution and high temperature. Therefore, it is...
