Filtering Operation :
Slurry is charges to gravity or pump vacuum is applied in bottle section through filte receiver

After 1st filtration is over, cake shall have almost 10 to 30% moisture
After 1st stage filtration , wet cake can be reslurried & spray washed by rotation agitator in clockwise & anticlockwise direction with up & down movement of agitator.
Cake is further pressed & Squeezed by rotating agitator in up & down motion to minimize liquid content in wet cake. Cake is discharged through Discharge nozzle by rotating agitator in reverse direction.
Drying Operation
For maximum recovery of liquid & drying vacuum is applied on top chamber & cake is heated by applying hot water / steam to form solvent vapour, which is turn is condensed in the condesor & collected in receiver.
