FG Series Vertical Fluid Bed Dryer
FG Series Vertical Fluid Bed Dryer(FBD)
Principle
The fresh air is filtered by the two or three filters and then enter into the heating system for heating . After heated , the hot air enter into the drying chamber and blow up the material in the bowl of the FBD and let the material into fluidization conditions .during this period , the material is dried . When customer use the machine , they can set the procedure and parameters according to the process requirements , and then start the machine.
The Machine Structures
1. INLET AHU
The inlet AHU consists of Primary filter(G4), Post filter (F8), high efficiency filter(H13 )and heater with accurate temperature control. The inlet air flow, speed and pressure is variable and controllable. For the heater , it can be steam radiator ,electrical heater , gas furnace and so on .
MAIN BODY STRUCTURE
The main body structure consists of bottom bowl, movable product bowl with trolley , fluidized chamber, expansion chamber/filter housing. The bottom bowl, product container and fluidized chamber are inflatable silicon gasket sealed with compress air inspection sensor to assure the reliable sealing.
3. PRODUCT FILTER
The double structured bag filter in two pieces (in case request, stainless steel filter available) is inflatable silicon gasket sealed between the expansion chamber inner surfaces with compress air inspection sensor to assure the reliable sealing. A dust sensor is mounted on the exhaust piping and interlocked from control sys to secure the product safety during processing stage.
4. EXHAUST AHU
The exhaust dust collection filter is optionally designed for protect environment.
Features
1. Fluidized bed to realize rapid heat transfer of medium.
2. Sealing negative pressure operation, no dust.
3. Since anti-static materials are used as filters, the operation is safe;
4. The equipment has no dead angle, which is convenient for comprehensive cleaning and no cross contamination;
5. Comply with GMP requirements.
6. HMI and PLC control system, motor speed is controlled by VFD, and all process parameters can be recorded.
