Problems solved by technology

The most prominent problem is the difficult separation of solid and liquid caused by the gelatinization of fine powder. Secondly, the high cost and low production capacity of ultrafine pulverization also restrict the promotion and utilization of superfine pulverization in the field of plant active ingredient extraction.

Embodiment 1

[0046] Such as figure 1 As shown: the upper end of the extraction tank 7 is connected with a feed pipe 2 and a liquid inlet pipe 6. The feed pipe 2 is used to transport the solid-liquid mixture of the material and the extraction agent to the extraction tank 7, and the liquid inlet pipe 6 is used to feed the extraction tank 7. The extraction agent is conveyed in 7, the feed valve 4 is provided on the feed pipe 2, and the liquid feed valve 5 is provided on the liquid feed pipe 6. The liquid inlet pipe 6 is also provided with a liquid inlet pump 12 and a liquid inlet flowmeter 9 in sequence along the conveying direction of the extractant. The amount of extractant delivered to the extraction tank 7.

[0047] The upper end of the extraction tank 7 is also connected with a voltage stabilizing module. The voltage stabilizing module includes a voltage stabilizing tube 1 and a condenser 2 . Due to the shearing effect of the circulation pump and the frictional shear between the materi...

Embodiment 2

[0064] Such as Figure 6 Shown: The difference between Embodiment 2 and Embodiment 1 is that: the continuous extraction device is not provided with a distribution pipe 33 and a distribution valve 34, that is, the solid-liquid mixture separated by the ceramic membrane 31 is sent to the plant superfine powder extraction device at the same level again In the extraction tank 7, a tank group continuous cross-flow extraction mode is formed. The continuous extraction device also includes a liquid collection pipe 36, a liquid distribution pipe 37 and a material distribution pipe 38. The mixed solution outlet of the ceramic membrane 31 is also communicated with the liquid collection pipe 36 through the liquid discharge pipe, and the liquid discharge pipe is provided with a liquid discharge valve. The liquid inlet pipe 6 of each extraction tank 7 is all communicated with the liquid pipe 37, thereby can replenish extractant in each extraction tank 7 by the liquid pipe 37, and the feed pi...

Abstract

The invention relates to a plant superfine powder extraction device, a continuous extraction device and an extraction process, which belong to the technical field of plant extraction. It is characterized in that the plant superfine powder extraction device includes an extraction tank (7), a circulation pump (16) and a ceramic membrane (31), and the bottom of the extraction tank (7) is fed through the circulation pipe (15) and the ceramic membrane (31). The end is connected, the circulation pump (16) is set on the circulation pipe (15), the solid-liquid mixture outlet of the ceramic membrane (31) communicates with the upper part of the extraction tank (7) through the return pipe (29), and the ceramic membrane (31) The outlet of the mixed solution communicates with the upper part of the extraction tank (7) through the liquid return pipe (35). The plant superfine powder extraction device realizes the extraction of plant superfine powder materials; the continuous extraction device realizes the continuous extraction of plant superfine powder materials; the extraction process can realize the minimum output coefficient of the output liquid, so that the concentration of the active ingredients in the extraction liquid can reach nearly saturation state.

Description

technical field [0001] The invention relates to a plant superfine powder extraction device, a continuous extraction device and an extraction process, which belong to the technical field of plant extraction. Background technique [0002] In the in-depth development and utilization of plant resources, the extraction of plant active ingredients is one of the most important links. The selection of extraction methods and extraction equipment is the key to determining whether the efficient and high-value utilization of plant resources can be realized. The active ingredients of traditional Chinese medicinal materials are usually distributed in the intracellular and intercellular matrix, mainly intracellular. The cell wall is a plant-specific structure that protects the protoplast. According to conventional methods, the active ingredients of Chinese herbal medicines must be infiltrated, swelled, permeated and diffused before they can be dissolved. The extraction rate is related to...
