How a combination weigher works
- Product falls onto a top cone that vibrates it out to radial feeders.
- Feeders fill pool hoppers, which drop into weigh hoppers with load cells.
- The controller evaluates combinations of weigh hoppers (for example 3–5 of 10 or 14).
- The best combination opens into the collecting chute and drops into the bag below.
- Empty hoppers refill while the bagger seals.
Multihead vs linear weighers
| Multihead (combination) | Linear | |
|---|---|---|
| Principle | Best combination of many hoppers | Each lane weighs a full or part dose |
| Speed | Higher | Lower |
| Products | Chips, nuts, candy, frozen food, irregular pieces | Sugar, rice, beans, seeds, free-flowing granules |
| Cost | Higher | Lower |

Accuracy and give-away
Our weighing systems list accuracy around ±1%, depending on product. Combination weighing reduces give-away versus volumetric dosing for irregular pieces — a direct saving on every bag.
Sticky and fragile products
Sticky products (dried fruit, gummies) need dimpled or coated contact surfaces; fragile chips need gentle feeders and short drops. Send samples so the weigher can be configured. See also weigher vs auger vs cup.
Questions and answers
What is a multihead weigher used for?
Weighing irregular products such as snacks, nuts, candy and frozen food quickly and accurately into bags, pouches or containers.
What is the difference between a combination weigher and a multihead weigher?
They are the same machine; “combination” refers to selecting the best combination of weigh hoppers.
Can a multihead weigher weigh powder?
No. Fine powders are dosed with an auger filler.
When is a linear weigher better?
For free-flowing granules such as sugar, rice and seeds at moderate speeds, where it offers lower cost.
