Multi-Head Combination Weigher & Weighing Scale for Granular Products

About Multi-Head Combination Weigher & Weighing Scale for Granular Products

A multi-head combination weigher, also called a combination scale, weighs free-flowing granular and piece products by constantly combining loads from many weighing heads to find the set closest to the target weight. This combination logic delivers high accuracy at high speed, typically better than a single-head or volumetric filler. It is the workhorse above vertical form-fill-seal baggers in snack, confectionery, nut, dried fruit, frozen vegetable and hardware packaging lines. The machine drops the selected product batch down a chute into the waiting bag, so line speed and pack weight stay consistent without weighing staff.

How to Choose

  • Number of weighing heads for the speed and accuracy you need
  • Weighing range and hopper volume matched to your pack sizes
  • Suitability for your product: dry granules, nuts, candy, pieces or frozen goods
  • Stainless steel frame and wash-down design for food line hygiene
  • Integration and speed matching with your bagging or form-fill-seal machine

FAQ

Q: How accurate is a combination weigher?
A: A well-maintained multi-head weigher typically achieves accuracy within roughly plus or minus 0.5 to 1 g on standard pack weights, which greatly reduces giveaway compared to volumetric filling. Exact figures depend on product shape and target weight.

Q: What products can it weigh?
A: It suits free-flowing solids that spread evenly across the feeders, such as snacks, nuts, candies, dried fruit, frozen vegetables, rice, beans and small hardware. Very sticky or very fine powder products may need special feeder options.

Q: How many heads do I need?
A: More heads mean faster weighing and better combination accuracy. A 10-head machine suits lower-speed lines, while 14 heads is the common choice for medium-speed snack and food packing, and higher head counts serve very high-speed production.

Q: Can it work with my bagging machine?
A: Yes. Multi-head weighers are normally mounted above vertical form-fill-seal baggers and matched for discharge speed and bag size. Give your packaging machine model and target line speed to confirm the right pairing.
