1. Overview
Scraper-type thin-film evaporator is the use of high-speed rotation into a uniform liquid distribution will be carried out thin-film evaporation or distillation of a highly efficient evaporation, steam Zi equipment, but also can be deodorizing, de-foam reaction and heating and cooling unit operation can be widely applied to Chinese and Western pharmaceutical, food, light industry, petroleum, chemical industry, environmental protection and other industries.
Centrifugal scraper film evaporator using foreign advanced technology, in domestic scraper field of thin-film evaporator has a leading position in the international level. This equipment served as a "scraper unit dense vacuum refining," the host, and won the State Pharmaceutical Administration Science and Technology for third prize.
2, performance and features
The device uses centrifugal rotor sliding groove, is the latest structure of foreign evaporator, in the case of small flow rate can also form a film evaporator in the cylinder wall surface treatment liquid attached to the activities of sludge scraper can be rapidly removed, and fixed scraper gap evaporator compared to evaporation can be increased by 40% -69%,
It has the following properties and characteristics:
1, the high heat transfer coefficient, evaporation capacity, evaporation intensity can be achieved 200kg/m2.hr, thermal efficiency is high.
2, the material heating time is short, about 5-10 seconds between the vacuum and under the conditions of work, and for heat-sensitive materials is more beneficial to keep a variety of ingredients does not produce any decomposition, to ensure product quality.
3, viscosity changes to adapt to a wide range of high and low viscosity materials can handle the material viscosity up to 100,000 centipoise (CP).
4, changing the direction of rotation groove scraper, you can adjust the care of the material in time for the evaporator.
5, evaporator cylinder wall through the precision boring, and polishing the surface, difficult to produce coke and scaling.
6, easy operation, product index adjust easily in confined conditions, continuous production can be controlled for.
7, equipment, small footprint, simple structure, easy maintenance and cleaning easy.
