Multihead weighing machine

continuousfor the food industryfor bulk materials

Overview
This complete granule packaging line integrates automatic feeding, a 14-head multihead weigher, vertical form-fill-seal (VFFS) bagging, filling and sealing. It is engineered for free-flowing granules and small pieces such as snacks, nuts, rice, coffee beans, pet food and plastic pellets. The line supports pillow, gusseted (stand-up) and hang-hole bag formats and is constructed with SUS304 food-grade stainless steel for product-contact parts.

Parameters

• Material type: Granules, pellets, small pieces (chips, nuts, seeds, hardware parts)
• Weighing range: 10–2,500 g per bag
• Packing speed: 10–60 bags/min (product dependent)
• Bag width: 50–200 mm
• Bag length: 50–300 mm
• Max film width: 420 mm
• Total power: Approx. 6.3 kW (380V + 220V)
• Main material: SUS304 stainless steel (food grade)
• Included: VFFS machine, 14-head multihead weigher, Z-bucket elevator, outfeed conveyor, working platform

Materials handled & bag styles
This line handles a wide range of free-flowing materials: potato chips, soybeans, rice, screws and small hardware, iron sand, pet food, coffee beans, nuts, seeds and plastic granules. The VFFS can produce different bag styles by changing the forming collar or bag former and adjusting machine recipes.

• Pillow bags (standard snack packaging)
• Pillow bags with hang hole (retail hanging display)
• Stand-up pouches / doypacks (gusseted bags)

How the line works
Bulk product is loaded into the Z-bucket elevator hopper. The elevator feeds material to the 14-head multihead weigher, where each head measures small portions and the controller selects the optimal combination to reach target weight. The weigher discharges the dose into the VFFS machine. The VFFS forms bags from roll film, fills with the weighed dose and seals the bag. Finished bags are discharged onto the outfeed conveyor for manual packing or further automated processing.

Equipment included

• Vertical Form-Fill-Seal (VFFS) machine: forms, fills and seals pillow or gusseted bags from roll film
• 14-Head Multihead Weigher: combination weighing for fast, accurate dosing
• Z-Bucket Elevator: automatic lifting of bulk granules to the weigher hopper
• Bag Former / Forming Collar: shapes film to the required bag profile
• Outfeed Conveyor: transports finished bags to the next stage
• Working Platform: operator access for maintenance and cleaning

Main features

• Turnkey integration of feeding, weighing, bag forming, filling and sealing
• PLC control with touchscreen and recipe storage for fast product changeover
• High weighing accuracy from 14-head combination weighing (typical 0.1–1.0 g, product dependent)
• SUS304 stainless steel product-contact parts for hygiene and easy cleaning
• Flexible bag style capability: pillow, gusseted and hang-hole bags using the same line

Advantages for buyers

• Reduced overfill and material waste through precise multihead weighing
• Design for maintainability: quick-release hoppers and tool-free disassembly for cleaning and changeover
• Reliable continuous operation using internationally sourced controls and drives
• Short operator learning curve with recipe-based control and built-in help menus
• Turnkey supply: complete system for streamlined installation and commissioning

FAQ (selected)

• Q1: What types of granules can this machinery handle? Free-flowing granules such as snacks, coffee beans, rice, seeds, pet food, plastic pellets and similar small pieces.
• Q2: Do I need extra equipment to change bag size? A bag former is provided to change bag length; different bag widths require a different forming collar.
• Q3: Is a semi-automatic option available? Yes. Semi-automatic filling options are available depending on budget and required output.
• Q4: How is price determined? Price depends on optional parts (metal detector, custom formers) and selected accessories. Provide bag size and material for an accurate quote.
• Q5: Do you provide installation and training? Manuals, videos and online support are included; onsite engineer visits can be arranged where applicable.
