Purpose:

This multifunctional extraction, concentration, and recovery pilot equipment is particularly suitable for research institutions, universities, hospitals, and pharmaceutical factories to develop new products and produce them in small quantities. Or the extraction and concentration of valuable drugs, or plants

The low-temperature extraction and concentration of fresh products have been successfully applied in factories. The equipment has successfully entered the foreign market due to its multiple functions, good performance, compact structure, and excellent mechanical performance.

Small scale multi-functional extraction and concentration unit, small extraction and concentration tank, laboratory extraction and concentration principle:

Put the prepared material into the extraction tank, add 5-10 times the amount of solvent (solvent properties and amount added according to the process requirements) at once, soak for a certain period of time, then turn on the steam valve to heat it up. Generally, take

Heating with a jacket (direct steam heating is only used when extracting aromatic oil from water), after a set time of boiling, the higher temperature extraction liquid can be continuously filtered through a filter screen from the bottom of the extraction tank

Then it goes to the filter and enters the concentrator. Steam is generated during concentration and enters the condenser, becoming condensate, which is sprayed as a new solvent into the extraction tank; Extract the secondary steam generated in the tank and cool it through the condenser

Condense into condensate and fall back into the extraction tank. All the steam generated by the solvent is converted into condensate through heat exchange and returned to the extraction tank. The secondary steam is fully utilized in the process, forming a new one

Solvent reflux extraction ensures high gradient mass transfer and high-speed dissolution of solutes and solvents in medicinal materials. So this equipment has excellent performance in energy saving and maintaining solvent balance.

The new solvent dissolves the soluble substances in the medicinal herbs from top to bottom through the medicinal layer, reaching the bottom of the extraction tank and then being drawn into the concentrator. Repeat the above process, and the resulting solvent is extracted and concentrated (recovered)

After multiple cycles, the extraction solution becomes colorless. At this point, the extraction solution stops being drawn into the concentrator. The concentrator continues to concentrate until the required specific gravity (1.1-1.25) of the liquid extract is reached, and then releases it

spare.
