Granule Vertical Form Fill Seal Machine with Combination Weigher
The ZSYAN SY-VFFS-G Granule Vertical Form Fill Seal Packaging Machine is a turnkey combination system engineered for dry granules, snacks, grains, seeds, and hardware from 10g to 2500g at speeds up to 80 bags per minute. Paired with a 10 or 14-head high-precision combination multihead weigher (accuracy ±0.2g to 1.5g), it integrates automatic film pulling, pouch forming, batch dosing, gas flushing, and thermal sealing. Built with food-grade SUS304 stainless steel contact parts and a heavy-duty mezzanine platform, it guarantees clean, zero-leak packaging across BOPP, laminated foil, and polyethylene materials.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
Integrated Combination Multihead Dosing
High-speed load cells calculate the optimal weight combination in milliseconds, eliminating product giveaway and saving thousands of dollars annually in ingredient costs.
Optional Nitrogen Gas Flushing
Injects high-purity nitrogen before cross-sealing to achieve residual oxygen levels below 2%, extending snack and nut shelf life up to 12 months.
IP65 Waterproof Washdown Design
Weigher hoppers and chutes feature quick-disconnect tool-less latches for easy sanitation with high-pressure warm water.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Snacks & Confectionery: Potato chips, puffed balls, candy, gummy sweets, popcorn, cookies.
- Grains & Dried Foods: Rice, quinoa, dried beans, rolled oats, coffee beans, dehydrated fruits.
- Nuts & Trail Mixes: Roasted peanuts, cashews, almonds, walnuts, seeds, raisins.
- Non-Food Granules: Plastic pellets, wooden beads, metal screws, furniture hardware fasteners.
❌ Unsuitable Products & Alternative Systems
- Fine Powders Under 100 Mesh: Flour, milk powder, cement (dust escapes weigher hoppers; use our SY-VFFS-P auger model).
Turnkey Packaging Line Integration Workflow
Seamlessly pair with upstream feeding and downstream end-of-line case packing equipment.
Z-Bucket Elevator
Continuous flighted conveyor feeds granules to top combination weigher.
Multihead Batch Weighing
14 hoppers compute target weight combination within ±0.5g.
VFFS Collar Funnel
Batch drops into formed vertical film tube through smooth mirror-polished chute.
Hermetic Sealing & Gas Flush
Nitrogen flush injection followed by dual-servo heated cut-off.
Inspection & Takeaway
Finished pouch passes through checkweigher and metal detector.
Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q How high does my factory ceiling need to be?
A standard VFFS system with mezzanine platform and multihead weigher requires a minimum ceiling clearance of 3.2 meters to 3.8 meters. For lower ceilings, we offer low-profile compact integrated frames.
Q Can the weigher handle mixed product ratios (e.g. trail mix)?
Yes. Our multi-mix multihead weigher can be partitioned into 2, 3, or 4 independent sections to dose exact proportions of almonds, cashews, and raisins simultaneously into each pouch.
