Title:
MICROWAVE ROTARY FILM CONCENTRATOR
Document Type and Number:
WIPO Patent Application WO/2008/095422
Kind Code:
A1
Abstract:
A microwave rotary film concentrator comprises an enclosed tank (1), a rotary evaporator (2), a microwave device (3), a discharge pipe for concentrated liquid (5), a condensor (6), a microwave shielding device (7), a stirring motor (8) and a vacuum system. The evaporating surface of the rotary evaporator (2) is tapered or round shaped. The angle (a) between the axis and the horizontal plane is 0 to 90˚. The rotary evaporator (2) indirectly connects to the external stirring motor (8) through a magnetic stirring device, and locates in the center of the enclosed tank (1). The enclosed tank (1) is provided with a lid which can be opened or closed. A sight glass (9) is on the lid. This invention has resolved many problems in concentration of the extracting liquid, such as slow evaporation rate, high concentration temperature, feed liquid decomposition due to be heated for a long time, unable to operate in reduced pressure as a result of intense boling of the feed liquid, low energy utilization, large dead volume, cleaning difficulty, etc. This invention has an extensive applied prospect.
