Equipment Description:

This device is suitable for plant herbs, traditional Chinese medicine, animal medicine, food additives, etc. Extraction using water, ethanol, methanol, acetone, and recovery and concentration using organic solvents.

Equipment features:

1. The absorption rate of the ointment is 10-15% higher than that of the multi energy jar, and the ointment contains more than twice as many effective ingredients. Due to the continuous addition of hot solvent onto the medicinal surface during the extraction process, it passes through the medicinal layer at high speed from top to bottom

Dissolve the solutes in medicinal herbs. The solute content in medicinal herbs maintains a high gradient with the solute content in the solvent. The solutes in medicinal herbs dissolve rapidly until they are completely dissolved, resulting in a high extraction rate of effective ingredients,

Therefore, the rate of cream collection is high and the content of effective ingredients in the ointment is high.

2. Due to the high-speed dissolution of solutes, short extraction time, and synchronous concentration and extraction, it only takes 7-8 hours for medicinal materials to be concentrated into ointment, resulting in high equipment utilization.

3. The equipment is single, occupies a small area, and has a high utilization rate, so the investment is low.

4. Only one solvent is added for extraction, and it is circulated in a sealed device. The solvent in the drug residue can be basically recovered, so the amount of solvent used is more than 30% less than that in the multi energy extraction tank, and the consumption rate can be reduced

50-70%, which paves the way for the extraction and purification of active ingredients in traditional Chinese medicine using organic solvents.

5. Due to the use of concentrated secondary steam as the heat source for extraction, the extraction solution drawn into the concentrator is at the same temperature as the concentration, which can save more than 50% of the steam used. The operation is very simple and reduces the number of operators.

working principle:

Put the medicinal herbs into the extraction tank and add 5-10 times the solvent of the herbs, such as water, ethanol, methanol, acetone, etc. (according to the process requirements). Open the straight through and jacket steam valves of the extraction tank to heat the extraction solution

After boiling for 20-30 minutes, use a filter tube to draw 1/3 of the extract into the concentrator. Close the extraction tank and jacket steam, and open the heater valve to concentrate the liquid material. Secondary generation during concentration

Steam is sent to the extraction tank through the evaporator riser as the heat source and solution for extraction, maintaining boiling inside the extraction tank.

The secondary steam continues to rise, condenses into hot condensate through the condenser, and falls back into the extraction tank as a new solvent added to the medicinal surface. The new solvent passes through the medicinal layer at high speed from top to bottom and reaches the bottom of the extraction tank

The soluble active ingredients in are dissolved in the solvent inside the extraction tank. The extracted liquid is drawn into the concentrator through a filtration tube, and the secondary steam generated by concentration is sent to the extraction tank as a heat source and new solvent, thus forming a new solvent

Solvent reflux extraction maintains a high gradient between the solute density in the medicinal material and the solute density in the solvent. The solutes in the medicinal material dissolve rapidly until they are completely dissolved (the extraction solution is colorless). At this point, the extraction solution

Stop pumping into the concentrator, transfer the concentrated secondary steam to the cooler, and continue the concentration until it reaches the required specific gravity (1.2-1.34) of the ointment, which is then released for use. Extract colorless liquid from the tank

It can be placed in a storage tank for the next batch of reuse. The drug residue is discharged from the slag gate. If organic solvent is used for extraction, an appropriate amount of water should be added first, and a straight through and jacket steam should be opened. After recovering the solvent, the slag should be discharged.
