ZB500N Automatic Internal-Pumping Brick Vacuum Packaging Machine for Granules, Coffee Beans, Nuts and Grains
The ZB500N is a fully automatic horizontal vacuum packaging machine designed for granular products such as coffee beans, nuts, peanuts, grains, frozen food and pet food. It uses an internal pumping vacuum system: air is drawn out from inside the bag before sealing, producing a rigid, six-sided brick-shaped vacuum bag that is oxygen-free, compact and shelf-stable.
Integrated with a multihead weigher or volumetric cup filler, the line automatically completes bag pickup, filling, internal vacuum pumping, heat sealing, bag shaping, coding and output. The result is a premium retail-ready brick bag that stacks neatly, protects aroma and freshness, and reduces shipping volume by up to 40% compared with pillow bags.
Built with a food-grade stainless steel frame, fully enclosed glass safety guards and a Siemens PLC + Panasonic servo system, the ZB500N delivers stable, high-vacuum performance for coffee roasters, nut processors and grain exporters
1. Application
Industry: coffee roasting, nut processing, grain / rice milling, frozen food, pet food, dried fruit.
Suitable products: coffee beans, roasted nuts, peanuts, cashews, almonds, rice, beans, grains, frozen dumplings, pet food, dried fruit, granola.
Suitable bags: six-sided brick-type vacuum bags, aluminum foil vacuum bags, laminated foil bricks.
2. Main Features
Internal pumping vacuum (内抽式): vacuum is drawn inside the bag before sealing, achieving a deeper, more uniform vacuum than external suction.
Six-sided brick shaping: after vacuuming, the bag is pressed into a rigid rectangular block — stacks perfectly, premium look.
Multihead weigher dosing (optional cup filler): accurate weighing for granules, ±0.5–1 g.
Fully automatic cycle: bag pickup → filling → internal vacuum → heat seal → shape → code → output.
Siemens PLC + Siemens touch screen, Panasonic servo drives, AirTAC pneumatics, Omron temperature control, Schneider electrics.
Fully enclosed glass guards with interlock switches — machine stops when a door opens.
Ribbon coder prints production date and batch number (up to 3 lines).
Vacuum level adjustable on the HMI for different products.

5. Why Brick Vacuum Packaging for Granules?
Keeps coffee beans fresh — no oxidation, no staleness, aroma locked in.
Moisture and pest proof — critical for nuts and grains shipped overseas.
40% smaller storage footprint — bricks stack flat, no air gaps.
Premium retail shelf appeal — gold/silver foil bricks look far better than pillow bags.

This vertical form-fill-seal (VFFS) powder packaging machine is designed for automatic filling and sealing of fine powders into pillow bags, gusseted bags and back-seal pouches. Integrated with a screw auger filler, it accurately doses flour, spice powder, starch, milk powder, protein powder and other free-flowing powders directly from film roll — no pre-made bags needed. Compared with vacuum brick bag machines, this VFFS line runs faster (up to 40–60 bags/min), takes up less floor space and costs significantly less, making it the best choice for powder producers who need high output at a competitive price. An optional nitrogen flushing unit can be added for products that need oxygen protection without full vacuum
