Problems solved by technology

[0003] Some existing extraction and concentration equipment are not convenient for continuous feeding, continuous discharging, continuous slag discharge, and continuous solvent recovery under closed conditions, and during the spiral extraction of medicinal materials, some medicinal residues are easy to adhere to the screw. The inner wall of the continuous extraction machine is inconvenient to fully extract the medicinal materials, resulting in waste of raw materials

Abstract

The invention discloses efficient energy-saving heat pump continuous extraction and concentration equipment, and belongs to the field of extraction and concentration. According to the efficient energy-saving heat pump continuous extraction and concentration equipment, secondary steam generated in the continuous extraction and concentration process is condensed into a solvent through a working medium condenser at the top, and the solvent serves as a new solvent and continuously returns to one end in a spiral continuous extraction machine, so that the surface of an extracted plant is continuously updated, the extraction time is shortened, the extraction efficiency is improved, and a higher concentration difference in the spiral continuous extraction machine is effectively ensured; and meanwhile, the new solvent returned to the spiral continuous extraction machine continuously and reversely flows to play a dynamic role, liquid medicine of dissolved effective components enters a working medium falling film evaporator and is concentrated, continuous feeding is carried out under a closed condition in the whole operation process, and continuous material discharge, continuous slag discharge and continuous solvent recovery are realized. The equipment is suitable for production operation, facilitates full extraction of medicinal materials, and reduces the possibility of raw material waste.

Description

technical field [0001] The invention relates to the field of extraction and concentration, and more specifically relates to a high-efficiency energy-saving heat pump continuous extraction and concentration equipment. Background technique [0002] Concentration is the unit operation of removing part of the solvent from the solution, and it is the process of partial separation of the solute and the solvent. During the concentration process, the water in the material is removed from the inside of the liquid phase to the surface of the liquid phase by convection and diffusion, and the final water mass fraction is about 30. %, generally in a stable state, the concentration of the solution is increased by evaporating the solvent, which generally refers to the reduction of the unnecessary part and the increase of the relative content of the required part. It is mainly used in the chemical industry, and the concentration technology is widely used in the processing of agricultural and...
