The centrifugal-type scraper film evaporator uses the overseas vanguard technology, has the international standard leading position in the domestic scraper type film evaporator domain. This equipment once took the scraper type vacuum builds up the dense unit the main engine, and has the honor to receive the National Medicine Administrative bureau advance in technology third prize. Performance and characteristic This equipment uses the centrifugal-type glide trench rotor, is the present overseas newest structure evaporator, can also form the thin film in the current capacity very small situation, may move in the tube body evaporation section endophragm surface adhesion processing fluid's siltation the scraper to remove rapidly, compares with the fixed gap's scraper evaporator, the transpiration rate may enhance 40-69%, it has the following performance and the characteristic: 1st, the heat transfer coefficient value is high, evaporative capacity is big, the evaporation intensity may achieve 200kg/m2hr, the thermal efficiency is high. 2nd, the material heating-up time is short, between 5 from approximately seconds to 10 seconds, and works under the vacuum condition, more is advantageous to the heat-sensitivity material, maintains each ingredient does not have any decomposition, the quality assurance. 3rd, the adaptation spread of viscosity is broad, the height viscosity may process, the material viscosity may reach as high as 100,000 centipoises (CP) 4th, the change scraper trench hand of rotation, may adjust the material to handle the time in the evaporator. 5th, the evaporation section tube in vivo wall undergoes precise boring and the polishing treatment, the surface is not easy to have coking, the scaling. 6th, the ease of operation, the product target adjustment is easy, under the airtight condition, may automatic control carry on the continuous production. 7th, the equipment area is small, the structure is simple, the service is convenient, the clean is easy.
