Bag Lifting Centrifuge
Febchem Engineering manufactures bag lifting centrifuges (also called bag-type or bag lifting basket centrifuges) in 24, 36, 48 and 60 inch sizes for pharmaceutical, API, chemical and food plants. After the spin cycle, the removable top ring and filter bag lift out together, so the cake is discharged without scraping or manual handling. This reduces operator contact and cross-contamination. Built in SS304/SS316 with cGMP construction.
How Does a Bag Lifting Centrifuge Work?
A bag lifting centrifuge is a top-discharge filtering centrifuge in which the filter bag is fixed to a removable top ring. After the spin cycle, the ring and bag are lifted out of the basket together, discharging the cake without scraping or manual scooping.
Industrial Centrifuges are widely used for efficient solid-liquid separation across pharmaceutical, chemical, food processing, and other process industries. The Bag Lifting Centrifuge is designed for hygienic operation, safe product handling, and high separation efficiency.
In Bag Lifting Centrifuges (Bag Lifting Type Basket Centrifuges), bag is fastened to a removable top ring, which acts as the lip of the basket. During operation the ring is fastened to the basket.After centrifugation, the lid of the machine is opened, and the product is discharged by detaching the removable top, which comes out along with the filter bag.
A hydraulic lifting device is used to lift the filter bag safely and efficiently. The lifting system can be installed next to the machine within the GMP area, ensuring hygienic product handling and faster batch discharge.
Available Capacities - 24 , 36 , 48 , 60 Inch
Bag Lifting Centrifuge Operating Cycle
- Charge: the slurry is fed into the basket lined with the filter bag.
- Spin and filter: centrifugal force pushes the liquid through the bag and basket perforations, and the solids stay behind as a cake.
- Wash and spin dry (optional): wash liquid displaces residual mother liquor, then a higher-speed spin reduces moisture.
- Stop and open: the basket comes to rest and the lid opens (hydraulically operated).
- Lift and discharge: the top ring with the bag is lifted out, manually or with the hydraulic lifting device, and the cake is discharged into a container.
- Re-bag and clean: a fresh or cleaned bag is fitted to the ring for the next batch.

Bag Lifting vs Other Centrifuges
Bag lifting | Manual top-discharge basket | Peeler (horizontal) | |
Cake discharge | Bag lifted out with cake | Operator scoops cake out | Scraper peels cake automatically |
Operator contact | Low | High | Minimal |
Typical fit | Batch pharma/API, sensitive products | Small batches, non-critical products | High-throughput repeat batches |
Trade-off | Bag handling between batches | Contamination and effort | Higher cost, scraper contact with cake |
Benefits of Bag Lifting Centrifuge Equipment
Here are key benefits based on the Bag Lifting Centrifuge process:
Easy Product Discharge
the bag lifts out with the cake, so no manual scooping.
Reduced Product Contamination
less operator contact during unloading.
High Separation Efficiency
effective liquid removal through the filter cloth.
Low Maintenance
fewer moving parts in the discharge mechanism
Safe Operation
the lid and interlock arrangement protects operators.
Suitable for GMP Applications
cGMP design with cleanable surfaces.
Frequently Asked Questions About Bag Lifting Centrifuge
What is the working principle of a bag lifting centrifuge?
A bag lifting centrifuge is a top-discharge filtering centrifuge in which the filter bag is fixed to a removable top ring. After spinning, the ring and bag are lifted out together to discharge the cake without scraping. |
How does a bag lifting centrifuge work?
The two common industrial centrifuge types are filter centrifuges and sedimentation centrifuges, selected based on the material and separation process.
What is the cost of a 12000 RPM centrifuge machine?
The cost of a 12000 RPM centrifuge machine depends on capacity, material, automation, and application. Contact the manufacturer for an accurate quotation.
What is the main function of a centrifuge?
The main function of a centrifuge is to separate solids from liquids or separate liquids of different densities using centrifugal force.
What is RCF and RPM in a centrifuge?
RPM measures the rotational speed, while RCF (Relative Centrifugal Force) indicates the actual force applied to the sample during centrifugation.
Which industries use industrial centrifuges?
Industrial centrifuges are widely used in pharmaceutical, chemical, food processing, wastewater treatment, biotechnology, and specialty process industries.
How do I choose the right industrial centrifuge?
Choose an industrial centrifuge based on product characteristics, capacity, operating speed, material of construction, automation level, and process requirements.
