Our integrated weighing and packaging system operates through a fully automated, continuous process:
1. Bulk Product Loading
Product is loaded into the Z-type bucket elevator's infeed hopper at floor level. The elevator's continuous chain of buckets transports material through a Z-shaped path—horizontal infeed, vertical lift, horizontal outfeed—to the multihead weigher's storage hopper at an elevated position
2. Product Distribution
From the storage hopper, product is distributed via vibratory feeders to each of the weigher's individual weighing hoppers. The vibratory feeders are independently controlled to ensure consistent material flow
3. Computerized Combination Weighing
Each weighing hopper is equipped with a high-precision load cell. The weigher's microcomputer calculates millions of possible hopper combinations in real-time and selects the combination that most closely matches the target weight. This multi-sampling stable mode delivers higher accuracy than single-head weighing systems
4. Discharge & Filling
The selected hoppers discharge simultaneously into the packing machine's forming tube (for VFFS) or into pre-made pouches. The system supports "no bag, no fill" functionality to prevent product waste.
5. Bag Forming, Sealing & Discharge
The packing machine forms bags from roll film (VFFS) or handles pre-made pouches, fills them with the weighed product, seals them, and discharges finished packages via conveyor belt
| Factor | Multihead Weigher System | Traditional Single-Head Weigher |
| Weighing Speed | Up to 120 weighings/min | 10–30 weighings/min |
| Accuracy | ±0.5g precision | ±2–5g or higher |
| Product Giveaway | Minimal—saves 1–3% material cost | Higher—significant product loss |
| Handling Difficulty | Food-grade polypropylene or stainless steel | Struggles with non-uniform shapes |
| Automation Level | Fully automatic, PLC-controlled | Semi-automatic or manual |
| Labor Requirement | 1 operator for multiple lines | Multiple operators per line |
| Changeover Time | 5–15 minutes (recipe storage) | 30–60 minutes |
Q1: What is a multihead weigher packing machine?
A multihead weigher packing machine is an automated system that uses multiple weighing heads with computer-controlled combination technology to achieve high-speed, high-accuracy portion weighing. Combined with a Z-type elevator for feeding and a packing machine for bagging, it provides a complete packaging solution
Q2: What does the Z type elevator do?
The Z-type bucket elevator transports bulk product from floor level up to the multihead weigher's storage hopper. Its Z-shaped design combines vertical lifting with horizontal travel in a compact footprint, making it ideal for space-constrained production facilities
Q3: What products can this machine handle?
The system handles granules, pellets, flakes, strips, chips, and irregular-shaped products—including snacks, nuts, candy, frozen food, coffee beans, rice, pet food, pharmaceuticals, and small hardware parts
Q4: What is the weighing accuracy?
Weighing accuracy reaches ±0.5g, depending on the model and product type.
Q5: What is the maximum packaging speed?
Speed ranges from 20 to 50bags per minute depending on the number of weighing heads and the packing machine configuration.
