Combined Weighing-Packaging Machine Solutions Overview
These systems combine precise dosing with automated bag formation, filling, and sealing in a synchronized line. Typical applications include fruits and vegetables, snacks, pet food, pasta, grains, frozen foods, and seafood. A combination weigher (multihead or linear) feeds a VFFS unit or a pre-made pouch packer, with infeed via a Z conveyor or belt. Downstream modules such as checkweighers and contaminant inspection help maintain consistent quality.
Configurations and Modules
VFFS + Multihead Weigher with Z Conveyor
A compact configuration that couples a 10/14/20-head combination weigher with a VFFS unit and Z-type infeed. Suitable for snacks, nuts, frozen foods, and pet food, it supports pillow, gusset, and quad-seal bags with options like nitrogen flush, easy tear, and zippers.
VFFS + Linear Weigher for Granules
For rice, sugar, seeds, and pellets, a linear weigher paired with VFFS offers stable accuracy and good value. Servo-driven film pull and precise temperature control promote repeatable seals and clean operation.
Pre-made Pouch Packer + Auger or Volumetric Filler
Powders such as flour, milk powder, seasoning, and coffee run well with auger or volumetric fillers. Dust extraction and anti-bridging features improve dosing stability, while tool-free disassembly and recipe memory accelerate changeovers.
Net Bag Packaging + Weighing for Produce
For citrus, onions, and potatoes, a gentle weigh-and-pack approach protects product integrity. Options include clip or band closures, labeling, and weight-based sorting for retail presentation.
Inspection and End-of-Line Options
Integrate checkweighers with feedback to the weigher and contaminant inspection (metal detection or X-ray). Add labeling, cartoning, case packing, and palletizing to complete the line.
Applications and Materials
Fruits and Vegetables
Gentle infeed, low-drop chutes, and optimized sealing reduce bruising and moisture-related seal issues. Perforation and MAP gas options support shelf life.
Snacks and Nuts
High-speed dosing with multihead weighers helps keep giveaway low. Nitrogen flush maintains texture, and anti-stick contact parts suit coated products.
Pet Food and Kibble
Robust frames and wide-format VFFS handle heavier fills up to multi-kilogram bags. Integrated checkweighers and inspection support compliance across SKUs.
Pasta, Grains, Rice, and Sugar
Linear weighers deliver accurate fills for free-flowing granules. Dust control helps protect seals and electronics.
Frozen Foods and Seafood
Materials compatible with low temperatures and anti-condensation design support reliability. X-ray inspection detects dense contaminants in frozen packs.
Performance and Specifications
Weighing Range and Accuracy
Typical dosing spans from small portions to multi-kilogram fills, using adaptive algorithms and optional checkweigher feedback to stabilize accuracy and reduce giveaway.
Multihead Weigher Options: 10/14/20 Heads
Choose 10-head for budget-sensitive lines, 14-head for mainstream speed, or 20-head for higher throughput and mixed products.
Throughput and Bag Sizes
Depending on product and bag style, speeds can reach up to 120 bags per minute on VFFS. Supported film widths and bag lengths cover small sachets through large retail packs.
Materials and Hygiene Compliance
Contact parts in SUS304/316 with IP-rated enclosures and FDA/HACCP/GMP-compatible materials support sanitation and washdown.
Controls and Software
Multi-language touchscreens, recipe memory, and USB-based updates simplify operation. Open protocols ease upstream and downstream integration.
Footprint and Utilities
Compact frames, ergonomic platforms, and optimized infeed heights help reduce floor space and installation complexity. Energy-efficient drives support lower operating costs.
Customization and Changeover
Product-Specific Contact Parts
Use Teflon-coated chutes for sticky items, dimpled surfaces for oily snacks, and gentle transfer paths for delicate produce to maintain accuracy and reduce damage.
Recipe Management and Quick Switch
Stored parameters for the weigher, bagger, coder, and inspection enable fast recipe changes with minimal startup waste.
Tool-Free Maintenance and Cleanability
Sanitary frames and easy-access enclosures support rapid cleaning and parts replacement.
Safety and Compliance
Food-Grade Materials and Protection
Guarding, interlocks, and IP-rated enclosures help protect operators and electronics during operation and washdown.
Traceability and Data
Batch coding, weight records, and rejection logs support audits and continuous improvement with exportable reports.
Project Delivery and Service
Turnkey Line Integration
We integrate sorting, weighing, packaging, sealing, labeling, cartoning, and end-of-line automation into a unified project with performance validation.
Commissioning and Training
On-site parameter optimization and operator training help protect OEE from day one.
Global Service Network
Spare parts, remote diagnostics, and local technicians sustain uptime, with upgrade paths for evolving formats and regulations.
FAQs: Combined Weighing-Packaging Machines
Q: What’s the difference between multihead and linear weighers?
A: Multihead weighers suit irregular items at higher speeds with low giveaway. Linear weighers are ideal for free-flowing granules where stable accuracy and cost-performance are priorities.
Q: Which bag types are supported?
A: Pillow, gusset, and quad-seal on VFFS; pre-made pouches with zippers or spouts on pouch packers. Options include easy tear, euro holes, and date/lot coding.
Q: How do you handle product changeovers?
A: Recipe-driven settings and tool-free contact parts enable rapid changes for weights, bag sizes, and products.
Q: How is quality ensured on the line?
A: Checkweighers provide feedback for fill control, while metal detection or X-ray identifies contaminants. Logs and batch data support continuous improvement.
