A. Introduction and Features Vacuum dry is to let the raw material to be dried at vacuum condition heating and drying. It uses vacuum pump to pump damp and make the working chamber form vacuum status. Therefore the dry speed of raw materials quickened and the energy is saved greatly. It is divided into static and dynamic drier. Model FZG round vacuum drier or Model FZG square vacuum drier belongs to static drier. Model SZG double cone rotating vacuum drier Belongs to dynamic drier. When raw material is dried in static drier, raw materials in static state and its shape can not be destroyed. Before drying, it can carry out the treatment of disinfection. When raw materials dried in dynamic drier, raw materials is turned over ceaselessly. So it can be dried better and more uniformly. In the state of vacuum the boiling point of raw material will be dropped. Therefore it is suitable for drying raw materials that are unstable or thermal sensitive. The vacuum drier also has good air-tightness. So it is also suitable for drying raw materials that contain strong irrigative and toxic gases and the solvent needs to be recovered. The vacuum drier has been widely used for pharmaceutical industry, chemical industry, foodstuff industry, dyestuff industry and so on.Model YZG-600 YZG-800 YZG-1000 YZG-1400 Internal size of drying cabinet(mm) Ø600 x 976 Ø800 x 1247 Ø1000 x 1527 Ø1400 x 2054 External size of drying cabinet(mm) 1135 x 810 x 1020 1700 x 1045 x 1335 1693 x 1190 x 1500 2386 x 1675 x 1920 Layers of drying holder 4 4 6 8 Layer distance(mm) 81 82 102 102 Size of baking tray(mm) 310 x 600 x 45 480 x 630 x 45 460 x 640 x 45 460 x 640 x 45 Quantity of baking tray 4 4 12 32 Pressure inside the baking support (MPa) <=0.784 Temperature of the baking support(¡æ) -35150 Unload vacuum inside (MPa) -0.1 Under the condition of -O. 1Mpa and 110 evapo ration rate of water (kg/m2·h) 7.2 Weight of drying cabinet(kg) 250 600 800 1400
