Agitated Nutsche Filter

Pressure Nutsche Filter can handle a variety of flow rates and solids loading that can be discharged in dry or slurried form. They can be designed for pressures up to 75psi or full vacuum.
Pressure nutsches are ideal for lab, pilot or batch applications and for easily filtered material such as carbon particles, salts and other products where a cake thickness of 6 inches or more can be attained.

Pressure Nutsche Applications:

• Ideal for piloting of new or modified batch operation and/or processes requiring recovery of the cake.
• The Pressure Nutsche is excellent for lab, pilot or batch applications where cake thickness of 6” and above is achievable.

Pressure Nutsche Features and Benefits:

• Manual and Automatic Models
• Easy recovery of cake in dry or wet form
• Available in alloy or rubber-lined construction
• No wasted heel (zero bypass)
• Designs from full vacuum to 300 psi or higher
• Wide variety of construction materials available
• Recovery of valuable solids where the filter cake is the product and filtrate is the waste
• Permits multiple processes to take place within the filter such as steaming, sparging, drying or washing
• Accommodates a wide variety of flow rates and solids loadings
• Porous cakes applications where cakes can build to several inches
• Pilot Plant studies
• Further treatment with Nitrogen purges or washes (acids)

The Industrial Agitated Nutsche Filter is a versatile machine used for drying as well as filtering. These machilayo are used in the manufacturing process of various chemicals, pesticides, insecticides, dyes, food products and pharmaceuticals. The unit consists of a totally enclosed and sealed cylindrical shell fitted with a agitator assembly which moves horizontally as well as vertically.
The cylinder operates under pressure or vacuum or both. A filter plate with filter cloth is fitted at the bottom of the shell for separating liquids from solids. The cake is retained on top of the plate. The upward and downward movement of the agitator assembly is utilised for cake washing, compressing, drying and discharge of the cake. A vacuum pump connected to receiver is installed for discharging of liquids and vapour collection. The cylindrical shell can also be provided with a jacket.

Salient Features:

• Closed batch types operation
• Repeated effiecient wash with reslurrying.
• Vacuum or pressure filtration
• Operation from Control panel
• No toxic fumes in operating area
• Very high Solvent recovery
• Minimum Labour required
• Drying of wet cake under Vacuum

Application:

• Pharmaceuticals
• Pesticides
• Organics/Inorganic Chemicals

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
