High Efficient and Centrifugal Scraper Film Evaporator for Wide Application
Summary.Scraper film evaporator is a high efficient evaporation ordistillation equipment, which distribute liquid to uniform thin film throughhigh-speed rotation for evaporation or distillation, and it can also carry outdeodorization, de-foaming reaction and heating, cooling unit operations, it canbe widely applicable to Chinese and western medicine, food, light industry,petroleum, chemical industry, environmental protection industry etc.
Centrifugal scraped film evaporator adoptsforeign advanced technology, stand at a leading position with internationallevel in the field of scraper film evaporator.
Performance and characteristics
This equipment is the newest structure ofevaporator in the world, also can form the thin film on the very small flow,The sediment in liquid adhere the cylinder inner wall surface at theevaporation period can be quickly removed by scraper, compared with fixed gap scraper evaporator,evaporation can improve 40-69%, it has the following features:
1.High heat transfer coefficient and evaporation capacity, evaporationintensity can reach 100kg/m2/ HR, high thermal efficiency.
2.Material heatingtime is short, between 5 to 10 seconds, and can operate in the vacuumcondition, more beneficial for heat-sensitive materials, keeping the variousingredients do not produce any decomposition, to ensure product quality.
3. Adaptable to large viscosity range, handleboth high and low viscosity material, material viscosity can reach up to 100000CPS (CP)
4.By changing thedirection of rotation of scraper trench, can adjust the material treatment timein the evaporator.
5.The evaporationsection of the inner wall of the barrel body through precision boring andpolishing treatment, the surface is not easy to produce coke, scaling.
6.Convenient operation, easy adjustment ofproduct index, can automatic continuous produce in airtight condition.
7.Equipment covers small area, simple structure, convenient repair, easyto clean.
