WFE-VB type shaves the membrane evaporimeter , it shaves form of the diaphragm and is similar to shaving the board agitator , uses a rigidity blade rotor equipment (Fig. 2). It blow diaphragm length and heat surface with high , according to blow diaphragm width and size of the evaporimeter adjust to and heat interval 1mm of cliff side, so does not produce wearing and tearing in heating the surface. It is easy to wash that this seals type structure and very smooth and superficial rotor , so, the supplies are suitable and in extensive range, very suitable for the food trade, GMP suitable for the medical trade too is required. It can deal with viscidity to probably product of 50,000mpas WFE-VB WFE-VB type blow rigidity blade , membrane of evaporimeter can make spiral form too , deal with viscidity can reach product of 70,000mpas at this moment 。 　　　Shave the board material and adopt the material the same as barrel of the evaporimeter 。

　　 Also call hinge blow membrane evaporimeter , it have one centre go back pivot , transport hinge blow the diaphragm (Fig. 3), they stick and become certain angle to slip in heating the cliff side closely by the centrifugal force, shave the supplies into the necessary liquid film, prevent heating the surface and forming the dirt , forms burntly . Offer effective impaction strength the design , rotor of types about liquid film (the high to evaporate than and concentrate not low) 。
　　 It is it heat surface apt form dirt , have solid particle or prone to crystallization in the course of evaporating and is it concentrate supplies that do to demand to suited to, deal with viscidity to 35,000mpas 。
　　 The type of this kind of rotor is used extensivly, by changing and shaving frequency of the board and quality, regulate the centrifugal force 。
　　 Shave the board material and usually adopt the metal material the same as barrel of the evaporimeter , can adopt PTFE material 。

　　d) WFE-Vd type shaves the membrane evaporimeter

Also call flexibility blow membrane evaporimeter , with cannelure to slip piece fix in " L " in the trough, depend on the centrifugal force and double load function of elastic strength and transform the supplies into the liquid film in heating the surface, pass and adjust in adjustable liquid film the time of staying of angle of cannelure too. This kind blow diaphragm pattern utilize elastic and load that strength produce , particularly suitable for the high viscidity and get the supplies that are inclined to together, it has very good cliff side to clean function by oneself 。 　　　It blows the diaphragm material for PTFE or formates such similar materials as the graphite ,etc. 。

● The WFE-KV type vertical cone shaves the membrane evaporimeter
　　WFE-KV type blows their of the membrane evaporimeter and shaves form of the membrane device and shaves one for rigidity , the structure is a round tapered barrel for the cylinder type barrel, underpart (low evaporating area ) for the top of the evaporimeter (high evaporating area ); Is it is it transfer cotyledon slice to to regulate to move by axial , can adjust rotor blow the diaphragm and heat the Taxi interval in low person who evaporate. It heat assurance surface the even to get moist,even not at concentrate low emission (the higher to evaporate than) when can get, meanwhile , can change thickness of liquid film (make a reduction of thin ) and the time of staying (extend), make the evaporation course here improved 。
　　It is very suitable for demanding the few products of implicit low boiling thing composition of remaining amount, viscidity is probably in 50,000mpas 。

● The WFE-KH type horizontal cone shaves the membrane evaporimeter
　　The horizontal cone shaves the membrane evaporimeter and is very similar to shaving the membrane evaporimeter round and tapered vertically , as for structure being similar, but the following performance are different ：
　　Light group one (low boiling thing ) and the liquid film (high boiling thing ) flow suitably , suitable for flowing into the overheated supplies directly, steam and enter the evaporimeter by flashing ；
　　It has longer the time of staying, and flow in the direction and gravity and become 90 degrees, still can be used as the reactor ；
　　Low space requirement, WFE-KH evaporimeter can be placed on if the existing building is highly restricted, it can not place the place of the vertical evaporimeter ；
　　This type evaporimeter is suitable for viscidity probably in 70000mpas ；
