Product Detail
Heat reflux extraction concentrator is a kind of substantial and efficient extraction concentrctor

Heat reflux extraction concentrator

Heat reflux extraction concentrator

First,    Main purpose

This equipment is suitable for plant herbs, Chinese herbal medicine with water, ethanol, methanol, acetone and organic solvent extraction recovery and enrichment. The units with room temperature extraction, low temperature extraction, vacuum concentration, solvent recovery and other functions.

Second,    Structure and characteristics

RCN Series refluxing extraction unit collector extraction and concentration, low temperature extraction, vacuum concentration process as a whole, reducing the process. Its characteristics are as follows

1 collection cans cream can increase the rate more than 10-15%, creams containing the active ingredient is 1 times more. As in the extraction process, the solvent continuously added to the drug hot surface, top to bottom layer of high-speed through herbs, medicinal herbs in the dissolved solute, the solute content of herbs and solvent containing dissolved to maintain a high quality gradient, herbs in the solute dissolution speed until completely dissolved, the active ingredient extraction rate, concentration of a sealing device in complete loss, conversion rate, high content of active ingredient in creams.

2. As high solute dissolution, extraction time, concentration and extraction carried out simultaneously, so the herbs to the cream concentrate only 7-8 hours, high capacity utilization.

3 devices a single, small footprint, high capacity utilization, investment.

4. An increase of only 1 solvent extraction, a sealing device in use within the loop, the solvent residue can basically recycling out, solvent extraction tank less than more than 30%, consumption can be reduced 50-70%, which and organic solvents for the extraction and purification of active ingredients in traditional Chinese medicine offers a more advanced process methods.

5. As for the concentrated extract of the secondary steam heat pumped into the concentrator and the concentrated extract of the same temperature, saving steam, easier to operate, reducing operator.

Third,    Principle and operation

Extract the herbs into the tank, add herbs 5-8 times the solvent (water,ethanol,carbinol

  acetone, etc., according to process requirements). Open the extracted steam jacketed tank through the valve and so extract heated to boiling for 20-30 minutes, with a leaching tube to 1 / 3 of the extract pumped concentrator. Direct extraction tank and jacket off steam, rising through the evaporator tube into the extraction tank for extracting the heat source and solution to maintain the extraction tank boiling.

Secondary steam continued to rise through the condenser condensing into hot condensate, down to the extraction solvent added to the tank for the new drug plane, the new top-down through the solvent extraction tank to the bottom layer of herbs, medicinal herbs of the soluble active ingredients dissolved within the solvent. Extract by filtration pumping into the concentrator tube, concentrated to produce secondary steam and extract a new tank for heat and solvent, creating a new solvent extraction of a large loop back through the degree, so herbs in the high solute dissolution, extraction is completed, extract was completely drawn into the concentrator, concentration of the secondary steam transferred to the cooler, concentration continues until the concentrated to the desired weight (1.2-1.34) of the cream, let stand. extraction tank residue, can be placed in tank use statistics for the next group, the dregs from the slag door drain, if using organic solvent extraction, the first increase the amount of water, open through the jacket steam, recycling the solvent, the residue drain.
