The hot reflux extraction concentrator meets the pharmaceutical GMP and food HACCP standards for extraction and concentration equipment has three national patent applications, has passed the provincial new product identification equipment features feeding volume. The dosage can be doubled compared to conventional extraction.
Good process adaptability. Can use atmospheric pressure, negative pressure, positive pressure process operation of water and alcohol extraction, especially the low temperature extraction of heat-sensitive materials, concentration. The low temperature of water extraction can be carried out above 45℃.
High cream yield. Because of the dynamic extraction of drugs, drugs and solvents containing solutes between high gradient, increasing the leaching impetus, increasing the rate of paste. It can extract more than 5%-20% more than the conventional method. Saving solvent. Fully closed closed loop, can save 30%-50%. Save time. Extraction and concentration can be completed in one step, and the unit adopts the return flow rate which is twice as large as the conventional one, the whole process only takes 4-6 hours.
Lower energy consumption. Because of the use of secondary steam as a heat source, extraction, concentration at the same time, and reflux condensate temperature is close to the boiling temperature in the extraction tank; and polyurethane foam for insulation insulation layer, the other temperature, vacuum is randomly self-control, the unit can save steam more than 50%.
The quality of medicinal ingredients of the extract is improved. Due to the short extraction time, temperature and random self-control, the quality of the extract is significantly improved.
High degree of automation. Temperature, pressure, flow, liquid level, concentration can be set, self-control, easy to operate, stable performance. Instrumentation, execution components, PLC are selected domestic and foreign brand-name products, high reliability.
The heated concentrator can be discharged on one side and fed on the other side, which is not easy to scale and coking. The specific gravity of concentrated liquid can reach 1.1-1.3, and the natural circulation can be changed to forced circulation system for special materials (easy to scale and coking materials). In order to meet the needs of customers' special materials.
New technology, new technology, new materials are applied, the unit has good performance. This unit where the drug, solvent contact instruments, equipment, piping and other materials are made of high-quality stainless steel. Internal are no dead ends, polished to a mirror, easy to clean; bottom cover sealing changed to pneumatic sealing, reliability improvement; extraction tank out of the liquid into a double filtration layer, not easy to block; extraction tanks, separators are set up double-action inertia de-foamer, the effect is good; heater using high finish thin-walled seamless tube; condenser using thin-walled small diameter seamless tube, double pipe course, heat transfer effect is good; the system is set up to raise the temperature of the heater, the configuration of the industrial computer, etc., making the unit process adaptability. This makes the unit's process adaptability, performance reliability and operation stability ahead of other similar units in China. It has passed the provincial new product appraisal, and the technology is leading in China. It has three national patent applications. According to customer requirements, can be designed for semi-automatic or manual operation.
