The system consists of following.
Bag Tilter.
Pre sieve hopper with horizontal and vertical screw.
Sifter
Post sieve hopper with horizontal and vertical screw.
Flour weighing and transferring vessel.
Diverter valves
Cyclone Separators.
PLC and Electrical Panel.
✔
Bag Tilter: The bag tilter consists of pneumatic cylinders and a SS tray on which flour bags are opened and placed. The operator operates a lever which activates the pneumatic cylinders to Lift and tilt the bag. The bag gets empted in to the Pre sieve hopper.
✔
Pre Sieve Hopper: The hopper consists of a horizontal and a vertical screw conveyor. The flour bags get emptied in to this hopper on the magnetic grill. The grill attracts any ferrous contamination. The flour is then transferred to the gyro sifter with the horizontal and vertical screw conveyor.
✔
Gyro sifter: The gyro sifter is used to sieve the flour which is fed by the vertical screw of the pre sieve hopper. The sieved material gets collected in the post sieve hopper.
✔
Post Sieve Hopper: The post sieve hopper is same as the pre sieve hopper. The sieved flour from the gyro sifter gets collected in the post sieve hopper. The horizontal and vertical screw conveyors are controlled by plc. The Post Sieve hopper will transfer the material to the weighing and transferring vessel also called as Pneumatic Pump.
✔
Pneumatic Pump: The Pneumatic pump is a weighing tank which is placed on the load cells. The tank is fitted with vent valve, flour inlet valve, Discharge valve. The tank is also equipped with pressure switch, Pressure relief valve and rapture disc to take proper safety of the equipment. The flour is charged in the tank from post sieve hopper by horizontal and vertical screws. The weight of the material is continuously monitored by the PLC. The PLC switch off the screws once the pre set quantity of material is fed. On demand from the operator the air blower starts and it pressurizes the tank and transfers the complete material to the cyclone separator.
✔
Diverter Valves: The diverter valves are used to divert the material to the selected Cyclone Separator.
✔
Cyclone separator: The Cyclone Separator is used to separate the material and the air. The air is vented out through the cyclone separator and the flour falls in the mixer below the cyclone separator.
✔
PLC and Electrical Panel.: The Plc controls the complete system. It has various menus like Run Status, manual / auto operation, System Diagnosis, Data Acquisition, Recipe Management, Calibration, Alarm Management. The electrical Panel controls all the motors, vibrators it has all the motor protection devices.
