| Feed System |
The cake is fed in the hopper is partially grated in the feed vat equipped with an agitator and then it is forced into the screw conveyor. The feed screw is provided with a variable speed drive. |
| Drying Chamber |
Vertical and cylindrical drying chamber is equipped with a rotor. Air is introduced tangentially at bottom through air distributor. Arm of each rotor and bottom plate having pins.All bearings are protected against dust and heat. |
| Pneumatic System |
System consists of cyclone, pulse jet dust collector, rotary air lock valves, blower and chimney to separate dry powder and air. |
| Hot Air Generator |
Mixed flow, direct or indirect heated, shell and shell type hot air generator is used to hot an air. System also consists of blower, burner, air filter and chimney. |
| Control Panel |
Temperature controller, feed controller, flow controller, pressure and temperature indicators with other indicating devices, automation and safety measures are provided according to application to measure various parameter to control operation automatically from control panel. |
To assist the fluidization caused by the flow of hot drying air through the air distributor. To disintegrate wet lump in the fluidized layer at the bottom of the drying chamber. The rate of evaporation is consequently increased.
The hot air flow creates a violent turbulence and eddy in the drying chamber. The half dried lumps will break because of the rotor and their attrition against each other. The airborne, fine powder particles then pass through the classifier at the chamber top. The classifier prevents the larger particles from passing on to the cyclone and/or pulsejet dust collector. These larger lumps tend to fall back into the fluid bed to continue drying. The powder is discharge continuously through rotary air lock valve fitted below cyclone and/or pulse jet dust collector while the drying air through the suction fan.
