Top-Notch Technology In Production Of Oils And Fats

AGITATED NUTSCHE FILTER/DRYER

Agitated Nutsche Filter is a closed vessel designed to separate solid and liquid by filtration under pressure or vacuum. The closed system ensures odourless 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.
GENERAL DESCRIPTION
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 specially “S” curved to take high torque generated during solid discharge and re-slurring operation.
PROCESS STEPS OF AGITATED NUTSCHE FILTER WITH AGITATOR AND DISCHARGE VALVE ARE:-
1) Filtration
2) Washing of Filter Cake
3) Repeat mix or washing of the cake
4) Convection drying of the cake
5) Smoothing with compression of the cake
6) Fully Automatic discharge of the wet or dried cake.

Drive assembly consist of Motor with Speed reducer, Lantern assembly with Stuffing-box/Mechanical Seal is provided. Manual/Hydraulic system is provided for movement of agitator and discharge Valve. Control Panel with Motor control relay ,fuse indicating lamp which will be installed in the safe area.
Material:
Stainless Steel , Carbon Steel , Hastelloy, Rubber or Plastic coated Steel. FILTER MEDIA
Sintered metal multi-ply of Textile.
SIDE DISCHARGE UNIT
Provided with hydraulically actuated door, sight glass, switch for safety locking, sealing arrangement with O-ring.
ADVANTAGES

• The equipment is functionally safe and easy to operate
• Minimum hold up of filtrate in the equipment
• Reduced manpower & no manual handling of product
• Agitator moves clockwise, anticlockwise, up and down. This ensures thorough washing and re-slurring of the cake.
• Toxic and hazardous material can be processed
• Product purity maintained
• Blending of product possible before discharging
• Product can be washed thoroughly and economically with solvents.
• Complete automation with PLC is available
• Combining filtration, washing, re-slurry and drying in one fully enclosed, automated unit permits reduction of capital and operating costs
• Heat transfer surface can be provided on the vessel wall by providing Jacket or Limpet Coil. Indirect Heating can be provided on the Filter base and Agitator.
• Large quantities can be processed faster than the conventional systems.
• The number of conventional machines employed for filtration process are also reduced.
