A multi-head combination weigher uses 10–32 independent weigh buckets that each hold a portion of product. A computer selects the combination of buckets whose weights add up closest to the target weight. Accuracy: ±0.1–0.3% for free-flowing granular products. Speed: 50–200 bags/min for small fills. Best for high-value products (premium rice, specialty grains, seeds) where accuracy and speed are critical. A linear weigher uses 2–14 heads in a row, best for longer, cylindrical products. For commodity grain in large bags (1–25kg), a single net-weight scale filler (platform scale or load cell) is often more economical.

Our grain filling machines handle: rice (all varieties — long grain, basmati, jasmine, sticky), corn (whole grain, grits, cracked corn), wheat grain and wheat berries, various beans (black beans, kidney beans, lentils, chickpeas), seeds (sunflower seeds, pumpkin seeds, sesame, chia, flaxseed), dried fruit and nuts (raisins, almonds, cashews — contact us for specific products), feed pellets, plastic pellets/granules, chemical granules, and coffee beans. Particle size range: 1mm pellets to 30mm whole grain.

Yes, with appropriate design features. For oily seeds (sesame, sunflower seeds) and nuts (peanuts, almonds), our multi-head weighers use titanium-coated or stainless steel non-stick coated buckets that prevent oily residue from building up. The bucket chutes use steeper angles to ensure oily products slide freely. For very sticky products (honey-glazed nuts, coated dried fruit), a linear weigher or volumetric scoop filler may be more suitable. Contact us with product specifications for the recommended configuration.

Multi-head weighers are most cost-effective for fills from 50g to 5kg. For smaller fills (50–500g), 14–32 head weighers are used for maximum speed and accuracy. For larger fills (1–25kg), 10–14 head weighers or net-weight scale fillers are more appropriate. For very large fills (25–50kg bulk bags), a dedicated large bag scale filler is used. The most common grain packaging sizes — 1kg, 2kg, 5kg retail bags — are in the optimal range for multi-head weigher efficiency.

A grain filling machine (multi-head weigher) is typically mounted directly above a VFFS (Vertical Form Fill Seal) bagger or a pre-made bag filler. The weigher discharges each weighed portion through a timing gate into the bag below. For VFFS integration, the timing is synchronised so the weigher releases product exactly when the bag is open and ready. For pre-made bag fillers, the bag is held open under the weigher discharge point. Integrated systems include a checkweigher and reject conveyor downstream for 100% weight verification.

Standard certifications: CE (European Conformity), ISO 9001:2015. Food industry certifications available: HACCP compliance (documented hazard analysis), BRC Global Standard for Food Safety, NSF/ANSI 51 (food equipment standard). For organic grain products, contact us for documentation support for organic certification audits. For export markets, we can provide CE Declaration of Conformity, test reports and origin documentation.
