EVAPOR is a Spinning Cone Centrifugal Thin-Film Vacuum Evaporator specially designed for the concentration of heat sensitive, viscous and high value products. The spinning cone of the EVAPOR not only helps to prevent foam formation but also decreases the contact time between the product and the heating surface to less than one second at evaporation temperature as low as 35oC to further reduce the thermal impact and preserve maximum functionality of the product active compounds. The centrifugal design also helps the EVAPOR to achieve higher concentration level than traditional evaporators. Benefits Low-temperature evaporation and extremely short residence time result in an ideal equipment for heat-sensitive quality products Foaming is minimized by centrifugal force Able to produce concentrates with considerable higher soluble solids level and higher viscosity than traditional plate or tubular

RIBOCONE is a multi-purpose equipment that can be used for mixing, drying, cooling, vacuum drying, filtration & (vacuum) drying and heating treatment (for decreasing of viable cells, for crystallization, for chemical reactions). Features Drive, gearbox and bearings are located outside of the vessel in order to prevent risk of product contamination due to lubricants, amongst others Its special design increases the circulation of the product inside the vessel resulting in a fast mixing and fast drying Uniform moisture content and temperature of the product due to total mixing of the product Complete discharge of the final product from the bottom of the cone due to no bearing Typical Applications Electronic and battery materials / Ceramics / Magnetic materials / Chinese herbal medicine / Seasoning / Animal feed / Resin powder/ APls, others

The slurry material is continuously fed into the fluid bed chamber which is filled with ceramic balls. As the material is supplied into the chamber it gets quickly dried by the combination of convectional heat from the fluidizing heated air and by conduction heat from the heated ceramic balls. The slurry material will adhere to the fluidized ceramic balls and will get instantly dry. During the process the collision of the ceramic balls will pulverize and make the dried product get peeled off from the balls. As the product gets dried it becomes lighter allowing to be conveyed by the fluidizing air and then discharged through the dust collector/ bag filter housing. This process guarantees a quality fine powder product with extremely low moisture content and particle size close to its primary one. Due to its high efficiency and its compact design “Slurry Dryer” has been widely used for the drying of chemical, ceramic, glass, battery material, metal, resin, among other slurries.
