Hot Reflux Extract Concentrator

Great quantity of feeding materials. The quantity of feeding materials is one time greater than common distillation type. Good technical adaptability. Water or alcohol solvent distillation in conditions of negative pressure, normal pressure and positive pressure, especially low-temperature distillation of heat sensitive materials can be made. High rate of ointment-collecting. Because of the dynamic distillation of medicine the solute content in the medicine and solvent keeps high gradient, which increases the pushing force of lixiviation and increases ointment-collecting rate.lt can extract 5-20% more than normal method. Saving solvent. Totally seal close-loop cycling.30-50%energy can be completed in one step,and concentration can be completed in one step, and re flux of this unit are greater by one time than common type. The period for whole procedure is only4-6 hours. Low-energy consumption. Second-time steam is used as heat source. Distillation and concentration can be made at one time. Temperature of reflux con densing liquids is nearly as same as boiling temperature in distillation tank. Foaming polyurethane is used as the heat preservation layer, and temperature,degree of vac uum can be controlled automa-tically. In the unit, above 50% steam can be saved. Quality of distilled medicines is greatly improved. The period for distill-ation is short, and temperature can be controlled automatically, so quality of distilled materials can be improved greatly. Highly automatic. Temperature, pressure, flow, liquid level and conc-entration can be set and in automatic control. It is easy to operate, stable in Performace. Allinstru ments, meters, executive devices and PLC are of famous brands from foreign counries. Therefore they are highly reliable. Inlet and outlet of materials are made at one time in the heating conc-entrator. So agglomeration and solidification are not likely to happen. Specific gravity of concenration liquit can be 1.1-1.3. To special materials (likely to agglomerate and solidify), natural cycling can be changed into compelled cycling for satisfying customer re quirements. New technolgies and new materials are utilized for excellent perfor-mance of unit. The areas of the unit contacting with medical liquids and solvents in instruments, equipments and pipes, are made of superior stainless steel. There are no any dead corners inside. Mirror is polished. It is easy to clean. The sealing of bottom cover is of air pressure seal to improve reliability. Distillation tank has two filtering layers to prevent jamming. Distillation tank, separator are attached with dual-purpose bubble eliminator. Seamless fine and smooth pipes are adopted in condenser. For having dou ble sides, they have good performance in heat transfer. Heaters and industrial control computers are attached in the system to make its adaptability, reliability and stability in performance and operation be in the leading place in China.
