Agitated Nutsche Filter is a closed vessel designed to separate solid and liquid by filtration under pressure or vacuum. The closed system ensures odorless contamination free and non-polluting working conditions maintaining product purity and hygiene. Agitated Nutsche Filters are extensively used in chemical, herbal, pharma, agro chemical and the food industry.The Agitated Nutsche Filter consists of a cylindrical shell with top dished and welded flat bottom. The base plate is stiffened by supports welded under the base plate. The base plate is having arrangement of bolting bar to hold the filter cloth. Suitable support mesh is provided under filter cloth to facilitate the flow of filtrate. Suitable nozzles are provided including Manhole and Side discharge nozzle. Solid bar is used for Agitator shaft and solid plate for blades made in especially S type curved to take high torque generated during solid discharge and re-slurring operation.

Salient Features

Material of Construction

• Carbon Steel
• Stainless Steel
• MS Rubber lined
• Hastelloy

Filtering Operation

• Slurry is charges to gravity or pump vacuum is applied in bottle section through filter 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 and steam to form solvent vapours, which is turn is condensed in the condenser collected in receiver.

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