Hygienic Top-Discharge Filtration for Peeler and Pusher Centrifuges

Skytech Ultrafab Centrifuge Top Lifting Bags are engineered for top-discharge peeler centrifuges where the filter bag and accumulated cake must be removed together in a single clean lift at the end of each cycle. The integrated lifting bands — sewn from high-tenacity polypropylene or nylon webbing — are rated to support the full weight of the wet cake during extraction, protecting operators from product contact and eliminating the contamination risk of manual cake removal.

What Is a Centrifuge Top Lifting Bag?

A Centrifuge Top Lifting Bag is a cylindrical filter bag with reinforced lifting loops or a structural lifting band sewn into or around the top edge of the bag. In a peeler centrifuge, after the spin and wash cycle is complete, a lifting tool engages the bands and extracts the bag with the retained cake intact. This allows product transfer to the next process step while keeping the material completely enclosed — essential for potent pharmaceutical compounds, toxic chemicals, and cGMP applications.

Features and Benefits

• Reinforced Lifting Bands: High-tenacity PP or nylon webbing loops rated for full wet cake load — stitched at multiple points around the bag circumference for even load distribution during extraction
• GMP-Compatible Materials: Bag fabric available in SS 316L contact-grade woven PP, polyester, and PTFE for pharmaceutical API and cGMP applications requiring full material traceability
• Precise Basket Fit: Fabricated to the exact internal diameter and depth of the centrifuge basket — correct fit eliminates bypass at the basket wall and prevents bag deformation under centrifugal load
• Reinforced Sidewalls: Heavy-gauge woven fabric sidewalls withstand G-forces up to 2000 G while retaining their shape and maintaining contact with the basket perforations
• Autoclave or Steam-in-Place Option: Autoclave-compatible fabric and webbing construction available for sterilisation requirements in aseptic pharmaceutical centrifuge applications
• Custom Lifting Geometry: Single-loop, multi-loop, and full lifting-collar designs available to match the lifting tool geometry of any OEM peeler centrifuge brand
