The Bag Lifting Centrifuge is specially designed for the solid-liquid separation of pharmaceutical intermediates, APIs, fine chemicals, and high-value crystalline products. The equipment adopts a bag lifting discharge structure, allowing operators to remove the entire filter bag together with the product cake after centrifugation, minimizing crystal breakage, material loss, and cross-contamination.

Compared with conventional manual discharge centrifuges, the bag lifting centrifuge offers cleaner product handling, improved batch consistency, and better compliance with pharmaceutical GMP production requirements.

It is particularly suitable for pharmaceutical intermediate crystals that are fragile, high-purity, toxic, or difficult to discharge manually.

Suitable Materials and Applications

The Bag Lifting Centrifuge is widely used in:

Pharmaceutical Intermediates

• Antibiotic intermediates
• Vitamin intermediates
• Hormone intermediates
• API intermediates
• Fermentation products

Fine Chemicals

• Organic crystals
• Specialty chemical intermediates
• Catalyst products
• High-purity chemical compounds

Food and Biotech Products

• Amino acids
• Food additives
• Fermentation crystals
• Nutraceutical ingredients

Pharmaceutical intermediate production often faces several separation challenges:

• Strict GMP and hygiene requirements
• High product value and low material loss tolerance
• Fragile crystals requiring gentle handling
• Frequent product changeovers
• Requirement for complete batch recovery
• Toxic or solvent-containing products requiring enclosed operation

The Bag Lifting Centrifuge addresses these challenges through a fully enclosed filtration system and convenient bag lifting discharge design.

Typical Benefits

• Complete crystal recovery
• Gentle handling of fragile crystals
• Reduced operator contact with product
• Faster batch discharge
• Lower cross-contamination risk
• Easy cleaning and maintenance
• GMP-oriented design

Step 1 – Slurry Feeding

The pharmaceutical intermediate slurry is fed into the centrifuge basket through a closed feeding system.

Step 2 – Solid-Liquid Separation

As the basket rotates at high speed, centrifugal force drives the mother liquor through the filter cloth and perforated basket.

Step 3 – Crystal Cake Formation

Solid particles are retained on the filter bag, forming a uniform filter cake.

Step 4 – Cake Washing (Optional)

Washing liquid can be sprayed onto the cake to remove impurities and residual mother liquor.

Step 5 – Final Dewatering

High-speed centrifugation removes residual moisture to achieve the target moisture content.

Step 6 – Bag Lifting Discharge

The filter bag containing the crystal cake is lifted out directly using a lifting mechanism, allowing quick and complete product removal.

Is this centrifuge suitable for GMP pharmaceutical production?

Yes. The equipment can be manufactured according to GMP requirements with SUS316L construction, polished surfaces, CIP systems, and enclosed designs.

Can the centrifuge perform cake washing?

Yes. Integrated washing systems can be installed for crystal purification and impurity removal.

What products are suitable for bag lifting discharge?

Products with high value, fragile crystals, sticky cakes, or applications requiring complete batch recovery are ideal.

Can explosion-proof configurations be provided?

Yes. ATEX-compliant and explosion-proof electrical configurations are available for solvent-based pharmaceutical processes.

What materials can be used?

Common options include SUS304, SUS316L, Duplex Stainless Steel, and Titanium.
