Rotary evaporators are widely used for large-scale sample concentration, drying, extraction, and recycling. They are ideal equipment for scientific experiments and industrial mass production as Chemical Rotary Evaporator, pharmaceutical Rotary Evaporator, food, environmental protection, and universities. It is understood that with the gradual promotion of energy saving and environmental protection in the pharmaceutical industry, pharmaceutical companies have made increasingly high demands on the energy saving and environmental protection performance of various devices. Among them, the rotary evaporator is one of the important equipments in the pharmaceutical production process. The rotary evaporator is energy-saving and environmentally friendly, which is of great significance for pharmaceutical production.

In the pharmaceutical process, the rotary evaporator is distilled under reduced pressure, that is, under decompression, and when the solvent is distilled, the distillation flask is continuously rotated. The distillation flask is a pear-shaped or round-bottomed flask with a standard ground joint connection. It is connected to a vacuum pump via a highly-return serpentine condensing tube. The other opening of the reflux condenser is connected to a receiving flask with a ground mouth for receiving. Evaporated organic solvents. There is a three-way piston between the condensing pipe and the vacuum pump. When the system is connected to the atmosphere, the distillation flask and the wetted flask can be removed to transfer the solvent. When the system communicates with the decompression pump, the system should be reduced. Pressure state. When the rotary evaporator is used, it should be decompressed first, and then start the motor to turn the distillation flask. At the end of the process, it should be stopped first and then open to the atmosphere to prevent the distillation flask from falling off during rotation.

Rotary evaporator uses a stepless speed regulation to rotate the glass rotating bottle at a constant speed. The material forms a large area of uniform film on the bottle wall. The intelligent constant temperature water bath is then used to uniformly heat the rotating bottle and evaporate at high speed under vacuum conditions. Efficient glass condenser cooling, recycling in collection bottles. In the pharmaceutical production process, the rotary evaporator is of great significance. However, with the prevalence of green pharmaceutical winds, energy conservation and environmental protection will become the trend of the development of rotary evaporators.

It is understood that on August 21, the Ministry of Environmental Protection, the Ministry of Development and Reform, the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of Finance and other 11 ministries, as well as the Beijing Municipal Government, the Tianjin Municipal Government, Hebei, Shanxi, Shandong and Henan Province issued the "Beijing-Tianjin-Hebei and surrounding areas The Action Plan for the Comprehensive Prevention and Control of Atmospheric Pollution in Autumn and Winter 2017-2018 (hereinafter referred to as the Plan). Compared with the 2016 plan, this year's environmental protection improvement scope and crackdown have increased. If 28 raw materials companies in the “processes involving VOCs emissions” are shut down in 28 cities, there is no doubt that environmental pressure will exacerbate the phase-out of the API sector, and even industry insiders will judge that 70% of raw material companies will die! Being eliminated, some of the dividends of the harvest, this is an industry consolidation process.

The concept of environmental protection is becoming more and more popular. As one of the key equipments in the pharmaceutical industry, the rotary evaporator can only achieve sustainable development after taking the energy conservation and environmental protection route, so that it can be favored by more pharmaceutical companies. For example, Shanghai Xinzhuang Instrument Co., Ltd. insists on environmental protection in the development process. In the production process, its rotary evaporator of the LNB brand relies on modern science and technology to continuously improve product quality. It promotes product energy saving and environmental protection and provides green pharmaceuticals with Advanced evaporation equipment.
