This unit is a new generation of energy-saving products developed by our company based on the advantages of similar products at home and abroad. It can concentrate and vacuum concentrate as one. Simplified operating procedures. At the same time, since the entire extraction and concentration are carried out in a dense state, phenomena such as “run” and “leakage” are avoided, which greatly improves the working environment and reduces energy consumption. The contact part of the unit and the materials are all made of high-quality stainless steel and meet the GMP standard requirements. This unit is suitable for the extraction and concentration of Chinese herbal medicines, fruit juices and other substances in hospitals, pharmaceutical factories, food industries and research institutes, and the recovery of organic coal.
