At present, some pharmaceutical chemical companies mostly use reactors to operate in the early stage of extracting and synthesizing pharmaceutical intermediates, because reactor was introduced earlier and is cheap, and it belongs to the early extraction equipment. However, with the development of science and technology and the expansion of production in the pharmaceutical industry, the operation process of the reactor can no longer meet the production needs of the enterprise, so the technical transformation of the reactor is a problem currently faced by pharmaceutical companies.

Common problems of reactor in the production process

  1. The stainless steel reactor currently used is washed with water six times, with 1 cubic meter of water added each time, for a total of 6 cubic meters of water.
  2. The first wash is at 80℃, and the remaining five washes are at 50-60℃. The material precipitates at room temperature. Each batch of material is 4 cubic meters.
  3. Each batch of materials is mixed for 1 hour and clarified for 40 minutes. The solvent is xylene.

Based on the existing problems of customer, it is found that the reactor has many problems during operation, and the operation process is very complicated, which requires technical transformation. Then, combined with the current extraction process, it is more appropriate to choose the CWL-M centrifugal extractor.
The CWL-M centrifugal extractor is a high-efficiency, new centrifugal extraction equipment developed and produced by Zhengzhou Tiei Extraction Technology Co., Ltd. Compared with traditional extraction equipment, the working principle is essentially different. The centrifugal extractor mainly relies on centrifugal force for mixing and separation, with a short mixing and mass transfer time, high extraction efficiency, larger processing capacity, and more energy saving. At the same time, it can be applied to a variety of liquid systems.

CWL-M centrifugal extractor separates two-phase materials under the action of high-speed centrifugal force. Whether in terms of performance, equipment appearance, technology and other conditions, centrifugal extractor is superior. It is an inevitable trend for new extraction equipment to replace traditional extraction reactor.
