hongda_FZG_series_square_static_vacuum_dryer.pnghongda_YZG_series_round_static_vacuum_dryer.jpg

Application:

Incorporated for high efficiency tray drying, using the combination of heat and vacuum in order   to optimize heat transfer from a wide range of reasonably free flowing materials. The feature of applying vacuum to the drying chamber ensures uniform and even drying throughout. Vacuum dry is divided into static and dynamic drier. The model YZG round vacuum drier of the model FZG square vacuum drier belong to the static drier type while the model SZG double cone rotating vacuum drier belongs to the dynamic drier type. When raw material is dried within the static type drier, the raw material is in static state and its shape remains stable. Where double drying is carried out within the rotary model SZG double cone unit, the drying time is lowered due to the continuous agitation of the material and the more even exposure to both heat and vacuum under the state of vacuum, the boiling point of the raw material will be lowered. Therefore these dryers are suitable for drying raw material that are unstable or thermally sensitive. The vacuum dryer also has good air retention and is suitable for drying raw materials that contain strong and toxic gases and where solvents need to be recovered. The vacuum dryer is widely used in the pharmaceutical, chemical, foodstuff and dyestuff industries and the design is in conformity with the requirements of GMP.

Note: SZ water ring vacuum pump can be used together with the mechanical pressure pump in order to increase the vacuum level.
