1. Overview and Basic Classification
We also call the multifunctional extraction and concentration unit a stainless steel extraction and concentration unit.
Essentially, it functions as a multifunctional processing system that integrates extraction and concentration.
Traditional Chinese medicine factories and biological extraction departments often use two types of such equipment.
One type is the thermal reflux multifunctional extraction and concentration unit.
The other type is small-scale extraction and concentration equipment.
Most small units rely on electric heating for operation.
By contrast, thermal reflux units usually adopt steam heating, which helps save energy effectively.
Notably, it is most commonly used in the pharmaceutical industry, especially for traditional Chinese medicine processing.

6. Extraction and Concentration Process
We use the high-position self-flow method for concentration during extraction.
Meanwhile, evaporated distilled water returns to the extraction tank for further extraction.
The entire reflux extraction and concentration process takes about 4-6 hours.
This process reduces steam and solvent loss significantly.
Moreover, it also shortens the overall operation time to improve productivity.

7. Solvent Recovery and Utilization
We directly send high-concentration solvent to the alcohol preparation tank.
There, it serves as solvent for the alcohol sedimentation tank or extraction tank.
On the other hand, we send dilute solvent to the dilute alcohol storage tank for future use.
The control box controls solvent discharge to achieve automatic liquid discharge.
This not only reduces labor intensity but also improves the solvent utilization rate.

10. Operation Steps
First, place herbs into the extraction tank carefully.
Next, add 5-10 times the herb volume of solvent (water, ethanol, etc.), based on process requirements.
Then, start the extraction tank’s heating system to boil the extract for 20-30 minutes.
After that, use a suction filter tube to transfer one-third of the extract to the concentration tank.
Subsequently, close the extraction tank’s direct heating and jacket hot water.
Then, turn on the concentration tank’s direct heating and heating system.
Finally, maintain the concentrate at around 80℃ and vacuum at -0.05 to -0.08 MPa.

11. Cycle Process and Residue Handling
Secondary steam from concentration passes through a condenser and cooler.
It then becomes condensed liquid and flows back to the extraction tank as new solvent.
The new solvent flows through the herb layer to dissolve soluble components thoroughly.
We repeatedly transfer the extract to the concentration tank to form a continuous cycle.
Continue concentrating until the desired ointment consistency is achieved.
The colorless liquid in the extraction tank can be reused for the next batch to save resources.
If using organic solvents, first add an appropriate amount of water, recover the solvent, and then remove the residues.
