Low energy consumption, stable rotating evaporator to promote green production of traditional Chinese Medicine

[product information of China Pharmaceutical network] the rotary evaporator is mainly composed of rotary motor, evaporation tube, vacuum system, fluid heating pot, condensation tube and condensation sample collection bottle It is mainly used for material concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries According to the introduction of the rotary evaporator manufacturer, under the vacuum condition, the bath pot is heated at a constant temperature, and the rotating bottle rotates at a constant speed, so that the material forms a large area of film on the bottle wall, and the solvent in the material is evaporated The solvent vapor is cooled by the glass condenser and recycled in the collecting bottle, which greatly improves the evaporation efficiency Because the water bath temperature of the rotary evaporator is relatively low, it is especially suitable for the concentration, crystallization, separation of high-temperature and easily decomposed biological products, solvent recovery, reflux extraction, etc In fact, there are not so many kinds of rotary evaporator as other products, and it can be used generally The main difference depends on the size of the evaporation bottle "If customers know how much capacity they need, vertical or horizontal, they can determine what kind of products they need." Rotary evaporator manufacturer said At present, the application of rotary evaporator is gradually expanding, taking the production of traditional Chinese medicine preparation as an example The author has learned that the current common extraction method of traditional Chinese medicine preparation is to use water or ethanol and other solvents for extraction and evaporation, so as to separate the volatile solvent and non-volatile solute in the solution, in which the rotary evaporator is used In the production process of traditional Chinese medicine preparation, it is required that the equipment structure of the rotary evaporator should be reasonable, the evaporation area should be large, the evaporation efficiency should be high, and it should have stable operation performance; the space in the evaporation room should meet the needs of concentration settlement and separation In addition, the equipment has good adaptability and can be used for concentration and evaporation of different pharmaceutical solutions The production of traditional Chinese medicine preparation is a more complex and high demand process Therefore, the equipment structure needs to be simple, the operation and maintenance needs to be more convenient, to meet the process requirements, and to maintain the stability of quality Of course, the key point is to reduce the power consumption of equipment, save energy and promote the production of energy conservation and environmental protection In the pre-treatment of traditional Chinese medicine, purified water or a certain concentration of ethanol are often used for extraction, especially organic solvents, which must be recovered The rotating evaporator works under vacuum condition The bath is heated at constant temperature, and the rotating bottle rotates at constant speed, so that the material forms a large area of film on the bottle wall, and the solvent in the material is evaporated Because of the continuous rotation of the rotating bottle, it is not easy to form dirt on the inner wall of the bottle so as to affect the heat transfer effect, and the solvent vapor is cooled by the glass condenser and recycled in the collecting bottle, greatly improving the evaporation efficiency Because the water bath temperature of the rotary evaporator is relatively low and the heat transfer is uniform, it is especially suitable for the refining, concentration, crystallization, separation and solvent recovery of traditional Chinese medicine preparations which are prone to decomposition and denaturation at high temperature Some experts also remind the operator that some necessary checks should be carried out before using the rotary evaporator For example, check whether the rotary evaporator has a cleaning signboard and an equipment intact signboard If there is no cleaning signboard or an equipment intact signboard or an equipment out of service signboard, the rotary evaporator shall not be used; check whether the rubber pipe used for vacuumizing has aging problems; check whether all the feeding cocks have been closed, etc After the equipment is used, it shall also be cleaned accordingly Experts suggest that clean the interface of the rotary evaporator with clean cloth and purified water According to the evaporation operation procedure, wash the rotating evaporator with water repeatedly until there is no residue by visual inspection Use the extraction bottle to extract the residual liquid in the evaporation bottle To turn off the vacuum, clean the outside of the rotary evaporator with purified water Seal all the openings with plastic bags and hang the cleaning signboard for standby If the rotating evaporator is found to be damaged or faulty, the maintenance personnel shall be informed immediately for replacement.
