Round Chamber High-Power Vacuum Packaging Machine

Engineered for 10–50kg Bulk Bags, Drum Mold Forming & Fine Powder Evacuation

Specially designed for heavy-duty bulk packaging of food ingredients, nuts, and industrial chemical powders. The circular internal vacuum chamber naturally accommodates upright 10kg to 50kg bags and cylindrical forming molds, eliminating corner stress and bag deformation. Featuring high-flow evacuation with an integrated industrial powder filtration system, it safeguards the vacuum pump while delivering clean, airtight, and compact drum-shaped packaging.

10–50kg Packaging Formats – Drum Barrels, Square Blocks, Vacuum Bricks & Retail Pouches

Multi-Format Packaging Flexibility: Compatible with cylindrical drums & barrels, standing square pouches, dense brick-formed blocks, and retail vacuum pouches from 10kg up to 50kg.

⚡ Core Engineering Features

1. Round Chamber for 10–50kg & Drum Molds
Specifically engineered for pre-filled standing bags (10–50kg). Naturally forms tight cylindrical packs and seamlessly integrates with round shaping molds.
2. One-Touch Automated Operation
Intuitive digital controls. Preset vacuum duration, heat seal time, and shaping hold time; simply close the chamber lid to execute the full automated cycle.
3. Universal Packaging Film Compatibility
Versatile high-output sealing bar supports any heat-sealable composite material, barrier nylon laminate, aluminum foil, or heavy-duty plastic pouch.
4. High Capacity & Customizable Chamber
Generous internal volume for oversized pouches. Chamber diameter, usable height, and sealing bar dimensions can be custom-built to your specs.
5. Tailored Pump Capacity (20–120 m³/h)
Configurable with premium domestic or German-engineered vacuum pumps. Capacities available from 20, 40, 60, 80, 100, up to 120 m³/h for rapid cycles.
6. Heavy-Duty Powder Filtration Unit
Integrated high-efficiency filter traps micro-dust and airborne particulates during deep evacuation, protecting the vacuum pump from clogs and wear.

Standard 10kg, 20kg, 25kg, or 50kg bag; drum barrel; or round forming mold.
2. Product Type & Dust Level
Solid nuts/beans, free-flowing grains, or fine powders requiring high filtration.
3. Pouch Material & Dimensions
Film type (PE, kraft, foil, woven) plus bag height and seal width.
4. Vacuum Pump Preference
Flow rate (20/40/60/80/100/120 m³/h) and brand specification (domestic or German).

Core Features & Advantages

Inline Dust & Powder Filtration System

Inline Dust & Powder Filtration System

Positioned directly upstream of the vacuum pump to intercept fine airborne particulates, chemical powders, and food dust during rapid evacuation, effectively safeguarding the vacuum pump against clogging and premature wear.

PLC Touchscreen & Emergency Safety System

PLC Touchscreen & Emergency Safety System

Intuitive touchscreen interface allows operators to precisely program vacuum duration, heat seal timing, and cooling cycles with recipe recall. Integrated with an emergency stop push-button for safe setup, rapid adjustments, and protected operation.

Adjustable Height Bag Support Baffle

Adjustable Height Bag Support Baffle

The internal support baffle features flexible height adjustment to perfectly adapt to varying pouch heights and fill levels (10kg to 50kg), ensuring upright stability and clean hermetic seal alignment.

Cylindrical Drum Mold & Direct Vacuum Shaping

Cylindrical Drum Mold & Direct Vacuum Shaping

Accommodates custom cylindrical forming molds or allows pre-filled bulk bags to be drawn directly into tight, uniform cylinder packs—ideal for drum packaging, space-saving pallet stacking, and heavy-duty transport.
