Bag Press

Applications & Use Cases

• Compacting waste materials such as packaging or product bags to reduce volume for disposal or recycling.
• Extracting residual liquids from solid materials contained within bags, common in food waste management.
• Densifying bulk ingredients or finished products in bags for more efficient storage or transport.
• Reducing the footprint of spent filter bags or other bagged process by-products.
• Pre-processing bagged materials before further shredding or granulation.

Typical Specifications

Typical compression force

Units of this type commonly offer compression forces ranging from 1 to 5 tonnes, depending on the pneumatic cylinder size.

Power supply

This equipment typically requires a compressed air supply, commonly 6-8 bar, and an electrical supply, often 400V 3-phase, for the conveyor and control system.

Bag size suitability

Bag presses are generally designed to accommodate standard industrial bag sizes, with the compression chamber dimensions dictating the maximum bag footprint.

Throughput

Throughput for this class of equipment is typically measured in cycles per minute, often ranging from 2 to 6 cycles, influenced by air supply and cylinder speed.

Footprint

The overall footprint, including the conveyor, can vary significantly but typically requires a floor area of 2m x 1m to 4m x 1.5m, plus operational space.

Construction material

For food processing applications, contact parts are commonly constructed from stainless steel, with the frame often being mild steel with a protective coating.

Frequently Asked Questions

• What type of air supply is required?

  A consistent supply of clean, dry compressed air, typically at 6-8 bar (90-120 psi), is essential for the pneumatic cylinder operation. The specific flow rate will depend on the cycle speed and cylinder volume.
