RH thermal circumfluence extraction & concentrator

Usage

The device services for vegetable and herbal medicine,Chinatraditional drug,animal drug,

food additional to extract with water,ethanol,carbinol and acet and to reclaim and concentrate

the organic solvent.

Work principle
1,The extraction of herbs into the tank, add herbs of 5 to 10 times the solvent such as water, ethanol, methanol, acetone, etc. (according to process requirements).

2,Open the extraction tank and the jacket steam through the valve, heated to boiling to extract 20 to 30 minutes, with a filtration tube to 1 / 3 of pumping into the concentrator extracts. Close direct and jacket steam extraction tank, open the heater valve so that liquid material for enrichment.

3,Concentration arising secondary steam rising through the evaporator tube into the extractor for extraction of heat source and solution to maintain the extraction tank boiling. Secondary steam continued to rise through the condenser condensing into hot condensate back to a solvent extraction tank for new drugs added to the surface, the new top-down high-speed solvent extraction tank through the layer to the bottom of herbs, medicinal herbs of soluble active ingredients dissolved in solvent extraction tank.

4,The extract was pumping into the concentrator tube filtration, concentration has taken the steam generated by the second extraction solvent tank to the heat source and the new, creating a new large solvent extraction and therefore the density of solute medicines containing the solute and solvent to maintain a high density gradient, high-speed dissolution of the solute in medicine, until completely dissolved (extract colorless), then the extraction stops pumping into the concentrator, concentrated in the secondary steam transferred to cooler, condensation continued until the concentrate into a need to share (1.2 ~ 1.34) in the ointment, released to be used.

5,Colorless liquid extraction tank may be placed in tanks approved for use under, residue from the slag door drain, if using organic solvent extraction, the first add the right amount of water, open through and jacket steam, solvent and , the slag drain .

Equipment characteristics

1. Collection cans cream can improve the rate of more than 10 to 15% cream contains active ingredients is 1 times. As in the extraction process, the hot surface of the solvent continuously added to the drug, from top to bottom layer of high-speed through herbs, medicinal herbs in the dissolved solute, the solute content of herbs containing dissolved with the solvent to maintain a high quality gradient, medicine in solute dissolution speed until completely dissolved, the active ingredients from high concentration in a sealed device has completed a small loss, conversion rate, so high income cream, cream in high content of active ingredients. 
2. As the speed of solute dissolution, extraction time, concentration and extraction simultaneously, condensed cream medicinal materials to only 7 to 8 hours of high capacity utilization. 
3. Equipment single, small footprint, high capacity utilization, so less investment. 
4. Extract only add a second solvent, in a closed loop inside the equipment used in the solvent residue can basically recycling out, it is more than solvent extraction tank, only 30%, consumption can be reduced by 50 ~ 70% , for using organic solvent extraction and purification of effective components of Chinese medicine paved the way for. 
5. As the concentration of the secondary steam for extraction of heat, pumping into the concentrator and the concentrated extract of the same temperature, which could save more than 50% of the steam medicine, the operation is very simple, reducing the operator.
