The development of the chemical and pharmaceutical industries is of great importance to human welfare, where mechanical separation and conveying equipment have been widely used. The decanter centrifuge and stack separator discs can be used to extract specific chemicals, classify and dehydrate chemicals and pharmaceuticals, and separate liquid mixtures of different densities. GN various transportation equipment and vacuum pumps for solids are also used in the transportation of chemical materials. In the chemical and pharmaceutical industry, users have a high demand for safety and stability. GN is committed to providing high-quality products to meet the requirements for safety and efficiency of operation. For these industries, GN took the best step forward to ensure product safety and reliability in product design and development aspects.
Separation and extraction of API (active pharmaceutical ingredient), pharmaceutical intermediates, teas, honeysuckle, Chinese yews, vitamin B5, pig brain protein, intestinal capsid, etc. API extraction process: network preparation, cutting, processing, drying, grinding, extraction (water extraction or solvent extraction: organic solvents such as ethanol), solid-liquid separation, ultrafiltration, concentration by evaporation (solvent recovery organic), drying, grinding, screening, packaging, sending to the preparation workshop for solids or liquids. In the solid-liquid separation process, GN C series explosion-proof high-speed decanter centrifuge or high-speed disc stack separator can be used to separate and remove impurities after alcohol precipitation to that the active ingredients dissolve in an ethanol solution; followed by high-temperature distillation of ethanol and complete separation of pharmaceutical ingredients. GN GNZS series vibrating screen can be used in the separation process
