Bag Lifting Centrifuge
Bag Lifting Centrifuge
Bag Lifting Centrifuge is an improvement over the Manual Top Discharge centrifuge and is now a very popular model.
In this model the Filter Bag is fastened to the Basket top plate. The Basket Top plate is in turn locked onto the basket shell.
When the filtration is completed the Plate is removed by unlocking the plate from the basket shell and pulled out using a hoisting arrangement. The filter bag containing the product comes out of the centrifuge. The product is then moved out to a suitable location and unloaded.
The Main Advantage of this machine is that the unloading time is reduced considerably and also has less manual intervention when compared with a manual Top Discharge centrifuge. High production rates can be achieved with this machine.
In this machine the Basket Shell is slightly tapered to facilitate easy pull out of the filter bag after the process is completed.
Sizes Available: Starting from 24” Dia. up to 60” Diameter.
Materials of Construction: SS 316, SS 304, SS904L, Hastelloy & Titanium
Coating: Halar (ECTFE), Teflon (PFA), Rubber Lining, FRP Lining
1. Full Lid Open: In this variant the top lid of the centrifuge has a large diameter that equals the diameter of the monitor casing. This gives better access to basket inside and outer periphery (except bottom) and full access to the top cover.
2. Full Body Opening : In this model the entire top cover of the centrifuge is accessible for cleaning and visual inspection. This is an ideal model for applications involving product changeovers and special cleaning needs. The basket bottom and the Mother Liquor Drain platform can be visually seen in this model. This model is often called cGMP or sanitary model.
The Lid is opened by using Spring Operated, Pneumatically operated or Hydraulically operated systems.
Optional Extras: Nitrogen Blanketing, Vibration Limiter, RPM Sensor with Indicator, Zero Speed Interlock, Cleaning in Place (CIP), Cake thickness sensor, Pneumatic Lid Opening System, Hydraulic Lid or Body opening systems, and Bag Lifting Device.

- 4 Point Suspension: Centrifuge is mounted on four viscous Dampers.
- Variable Frequency Drive: The operating speeds of the centrifuge are controlled by a Variable Frequency Drive. The Standard Braking System for this model is Dynamic Braking.
- Taper Lock Pulleys: These pulleys are easier to mount and dismount.
- Cake Washing Nozzles: Special Spray nozzles with defined conical pattern spray are provided so that the entire surface of the cake is covered uniformly with minimal quantity while maintaining repeatable washing performance.
- Shaft Protection Sleeve: A stainless Steel sleeve is mounted on the exposed part of the shaft to protect it from corrosion.
- Proximity Sensor: To prevent the machine from being started while the lid is open a proximity sensor is installed as a standard feature.
- Gas Tight Design: The machine is constructed to retain a positive pressure of 400mm WC as per DIN 24400.
- Easy Maintenance: The machine design affords minimal maintenance. Greasing points enable easy lubrication to the Bearings.
