BYP Series Closed cycle spray dryer
General description
This plant works in a closed environment, which needs to be dried in an inert gas atmosphere, generally filled with nitrogen. The closed circulation spray drying system is mainly used for products containing alcohol and flammable and explosive solvents in the slurry, or products which are easily oxidized and cannot be exposed in the air. By filling inert gas such as nitrogen, it can prevent the product from contact with air. The product produced by this plant has good consistency and good fluidity, and can produce spherical materials. Thus the plant is more suitable for high-precision ceramics (such as tungsten carbide, silicon nitride, and nano-ceramics), cemented carbide such as tungsten carbide powder, and pharmaceutical intermediates and etc..

Model BYP-20 Pilot closed-cycle centrifugal spray dryer
Commercial size Model BYP-30 closed-cycle centrifugal spray dryer
Application
For the sealed-circulation centrifugal spray drying machine , it is suitable for drying the solution, emulsion, suspending liquid and pasty liquid containing organic solvents, volatile poisonous and harmful gas, material which is easily oxidized and afraid of light and needs to be solvent recovery . It not only inherits all the advantages of centrifugal spray drier , but also there is no powder flying outside when drying operation . It can achieve 100% material collecting rate. Through the solvent recovery system ,the collected solvent through secondary processing , it can be recycled, which greatly reduces the production cost. Favored by the majority of users, which is widely used in the pharmaceutical, chemical, food and other industries drying operation.
Definition of closed-cycle spray drying
Closed cycle spray dryer in the drying chamber will be sealed into the mist droplets dispersed solid to liquid and hot medium (nitrogen N2) was dried droplet method of powder products. Atomized by rotary atomizer or a nozzle atomizer to achieve, droplet drying can be adjusted by the temperature or the flow of heat medium to be controlled, evaporation of the solvent to be recovered through the condensation unit, after "removal" and full " dewetting "of the media were highly efficient filters and returned to heat exchanger, and finally recycled into the drying system.
