In the fine chemical synthesis process, the extraction and washing (including water washing and alkali washing) processes are essential links. Their main purpose is to remove solvents and by-product salts from the reaction solution. However, at present, these two processes still rely on traditional kettle stirring and standing separation, which have problems such as low separation efficiency and long standing time, which seriously affect the efficiency of subsequent processing units. This results in a low degree of automation, long process cycles, large wastewater output, and high direct costs in the production of prepared compounds, which limits the improvement of manufacturing levels.
In order to meet the needs of continuous production in modern factories, Guizhou Landerlee Extraction Technology Co., Ltd. has developed a professional extraction machine based on the characteristics of extraction and separation such as nitrification reaction and synthesis reaction. The centrifugal extraction technology of this equipment realizes the contact mass transfer and phase separation of liquid-liquid phases by utilizing the centrifugal force field. It has the characteristics of compact structure, large processing capacity, smooth operation, low power consumption, and convenient cleaning and maintenance.
