Features
1. The rate of extracting the paste is 10~15% higher than that of the multi-energy extraction tank, and the active ingredient in the ointment is more than 1 times higher. Because the hot solvent is continuously added to the medicine surface during the extraction process, the medicine layer is passed from top to bottom at high speed. Solubility in the dissolved medicinal material, the solute content in the medicinal material and the solute content in the solvent maintain a high gradient, and the solute in the medicinal material dissolves at a high speed until completely dissolved, the extraction rate of the active ingredient is high, and the concentration is completed in a set of sealing equipment. The loss is small and the conversion rate is high, so the paste collection rate is high and the effective ingredient content in the ointment is high.
2. Due to the high-speed dissolution of solute, the extraction time is short, and the concentration and extraction are carried out simultaneously. Therefore, it takes only 7-8 hours for the medicinal material to concentrate the ointment, and the equipment utilization rate is high.
3. The equipment is single, the land occupation is small, and the equipment utilization rate is high, so the investment is saved.
4. Extracting only one solvent, recycling in a set of sealing equipment, the solvent in the dregs can be basically recovered, so the solvent dosage is less than 30% less than the multi-energy extraction tank, and the consumption rate can be reduced by 50~70%. This paves the way for the extraction and purification of active ingredients from traditional Chinese medicines with organic solvents.
5. Since the concentrated secondary steam is used as the heat source for extraction, the extract liquid drawn into the concentrator and the concentration of the same concentration can save more than 50% of the steam, and the operation is simple and the operator is reduced.
working principle
Put the medicinal material into the extraction tank, add 5~10 times of the solvent of the medicinal material such as water, ethanol, methanol, acetone, etc. (according to the process requirements), open the extraction tank straight through and the jacketed steam valve, so that the extract is heated to boiling for 20~30 minutes. After that, 1/3 of the extract was pumped into the concentrator with a suction tube. Close the straight-through and jacket steam of the extraction tank, open the heater valve to concentrate the liquid material, and generate secondary steam when concentrated, and send it to the extraction tank for the extracted heat source and solution through the riser of the evaporator to maintain the boiling in the extraction tank. The secondary steam continues to rise, condenses into a hot condensate through the condenser, and falls back into the extraction tank as a new solvent to be added to the drug surface. The new solvent passes from the top to the bottom and passes through the medicinal material layer to the bottom of the extraction tank. The soluble active ingredient in the medicinal material Dissolved in the solvent in the extraction tank. The extract is pumped into the concentrator through a suction filter, and the secondary steam generated by the concentration is sent to the extraction tank as a heat source and a new solvent. The new solvent thus formed is greatly refluxed, so that the solute density in the medicinal material and the solute density in the solvent are kept high. Gradient, the solute in the medicinal material is dissolved at high speed until it is completely dissolved (the extract is colorless). At this time, the extract is stopped and pumped into the concentrator, and the concentrated secondary steam is transferred to the cooler, and the concentration is continued until concentration is required (1.2 ~1.3) of the ointment, release the spare, extract the colorless liquid in the tank, can be placed in the tank for the next batch, the dregs are drained from the slag door, if it is extracted with organic solvent, first add the right amount of water, open Straight through and jacketed steam, after the solvent is recovered, the slag is drained.
