Continuous countercurrent ultrasonic extraction equipment 1

The company's core product - various models of continuous countercurrent (ultrasonic) extraction machines, which integrates 15 key technologies such as ultrasonic extraction, dynamic countercurrent extraction, continuous automatic slag removal filtration, continuous dynamic circulation evaporation concentration, residual solvent recovery, tail gas residual solvent recovery, special sealing, etc. It realizes continuous operation and automatic control under full sealing conditions, and achieves rapid extraction and concentration under low or normal temperature conditions. It is an efficient, energy-saving, and safe set The environment-friendly biotechnology equipment is widely used to produce traditional Chinese patent medicines and simple preparations, natural pigment, essence and fragrance, food additives, health care products, cosmetics, feed additives, plant pesticides and other products from natural plants, especially suitable for large-scale use of organic solvents to extract heat sensitive substances.

The continuous countercurrent reflux extraction machine is the company's first generation continuous countercurrent extraction machine and one of its core products. It embodies the company's six independently innovated invention technologies and is widely used in various plant extractions.

1. Workflow and principles

The extracted plant raw materials and extraction solvent (or extraction solution) are continuously pushed and flowed in opposite directions in the extraction tube (single-stage or two-stage), forming a continuous countercurrent extraction. The concentration of the extraction solution forms a continuous gradient from the inlet to the outlet, maintaining stable solubility throughout the process. The minimum amount of extraction solvent is used to achieve the maximum extraction rate.
