Hot reflux extraction enrichment unit principle:

Will make a good prescription medicine into extraction tank, one-time add 5-10 times the amount of medicine solvent (solvent properties and add quantity according to the technological requirements) soaked after a certain amount of time, open the heating steam valve, (direct steam heating water extraction of aromatic oil was mentioned only) after a set time after cooking, the higher temperature of the extract can be continuous from the bottom of the extracting tank after mesh coarse filter to filter, into the concentrator.Concentration when the steam entering the condenser as condensate, as a new solvent spray to extraction tank;Extraction tank to produce secondary steam, the condenser cooling into condensate, back into the extracting tank.All of the steam produced by solvent, through heat exchange be condensate returned to the extracting tank, full use of the secondary steam in the process, the formation of a new solvent reflux extraction, the solute and the solvent in medicine always maintain high gradient, mass transfer and instant。So the set of equipment in energy saving and balance of solvent is very superior performance.

New solvent from top to bottom by dissolving soluble content of medicinal herbs layer to the bottom of the extracting tank is pumped into the concentrator。Repeat the above process, thus forming the solvent by extraction, enrichment (recycling) circulation after return several times, extract shows colorless, at this point, the extract cease into the concentrator.Concentrator for enrichment, until meet need specific gravity (1.1 1.25) liquid extract, release and set aside.

Hot reflux extraction enrichment unit features:

1. Shorten the production time by 50%, again after many times extraction enrichment fax process.Two process and the technology of concentrated extract concentration within a set of equipment at the same time, a one-time only 4 to 6 hours.

2. More than 60%, saving steam of the formation of secondary steam in the concentrator can be used as extractor is direct heating of the heat source, and liquid with high temperature into the concentrator, the heat loss is very little.

3. 60% less solvent inventory, extract can of medicinal materials with a solvent, in the inner loop using a set of sealing equipment, medical and medicine liquid gas solvent can be recycled out basically (attrition rate under 5%), and so less solvent consumption, consumption, low cost of production has fallen dramatically.

4。 The extract rate can be increased by 10% - 20%, compared with the traditional technological efficacy content be doubled。For one-time injection solvent can realize large reflux circulation, make the medicine in the solute concentration and always maintain high solute concentration gradient in the solvent.So the medicinal materials of rapid dissolution of the solute。Extract shall remain valid and effective ingredients yield increased significantly, and quantitative appraisal to lay the good foundation for the drug。
