• Filtering Operation :

   

• Slurry is charges to gravity or pump vacuum is applied in bottle section through filte receiver

   

• Filtrate is collected through the filter bed & collected in Receiver, located below the lower compartment of filter & cake layer begin to form slowly on filter plate.

   

• 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.

   

• Cake is finally discharged automatically by vertical & reverse rotary movement of agitator.
