Rotary give-bag(pre-made bag) design — high seal quality with prefab bags
Horizontal bag-feeding device with zip-opening device
Top and bottom bag-opening with bag-open detection
Empty-bag circulation: bag that fails to open is re-routed and not filled, preventing empty packs
Two-stage tray vibration; dust-suction hopper; dust-sweep motor
Two-stage sealing; horizontal heat-sealing for hygiene(no dead zones)
Powder-specific conveyor belt; exhaust device

Material-contact parts: SS316L; non-contact mirror-polished SS304; vacuum parts: aluminum alloy with hard anodizing ≥5μm(salt-spray ASTM, no corrosion)
Drainage: tilted U-shaped water trough(60 mm wide, 80 mm above tabletop) with two diagonal drains and quick-connects
O-ring + U-ring seals at column bases and embedded box doors prevent liquid ingress
Self-lubrication system with oil-flow detection; alarms and stops on low oil
Phase-error / phase-loss / neutral-loss / surge protection
Recipe save/recall for fast product changeover
Bag bin level detection — alerts when low
Wear-part maintenance reminders
SMC mid-vent solenoid for sealing pusher; cold-shaping after vacuum sealing for clean seal pattern
Reserved Ethernet port — Profinet / S7 server for MES integration
Wide packaging range — suits all powder states/properties
Accommodates various pre-made bag types
Easy operation — PLC + HMI; intuitive control
Quick changeover — under 5 minutes
High automation — unmanned weighing + packaging with auto fault alarm
Anti-empty-pack: bag-open detection + circulation eliminates empty packs
GMP-compliant material-contact stainless steel
Imported-tolerance plastic bearings on selected parts — no oiling, less material contamination
Dust- and water-proof design — washable for easy cleaning, longer service life
Transparent organic-glass safety door
One-piece main frame with repeated alignment for absolute parallelism
