Why Your Factory Needs One Multihead Weigher Packing Machine ?

In the competitive world of manufacturing, precision is profit.

If you are packaging granular products—like potato chips, frozen vegetables, nuts, or hardware—using manual labor or simple linear weighers, you are likely facing a silent profit killer: “Overfilling” (Product Giveaway).

Even if you only overfill by 2 grams per bag, at a speed of 60 bags per minute, operating 8 hours a day, you could be giving away tons of free product every year.

The solution? The Multihead Weigher Packing Machine.

1. What is a Multihead Weigher? (The “Brain” of Packaging)

A Multihead Weigher (also known as a Combination Weigher) is a high-speed, high-accuracy weighing system used in packaging lines. Unlike a standard scale that measures weight linearly, a multihead weigher uses a computer algorithm to calculate the best possible combination.

How it works:

1. Distribution: Product is fed onto the top cone and vibrates into radial feed pans.

2. Weighing: The product drops into several “Weigh Hoppers” (buckets). The machine measures the weight in each individual bucket.

3. Calculation (The Magic): The onboard computer instantly calculates thousands of combinations of these buckets to find the subset that matches your target weight exactly (or closest to it).

4. Discharge: It releases only those specific buckets into the bagmaker (VFFS machine) below.

2. The Unbeatable Advantages

Why do food giants like Lay’s or Nestlé use Multihead Weighers?

A. Extreme Accuracy (Stop Losing Money)

Standard linear weighers might have an error margin of ±3-5g. A Multihead Weigher typically operates within ±0.1g to 1.5g, depending on the product size. This drastic reduction in giveaway means the machine often pays for itself in raw material savings within the first 6-12 months.

B. High-Speed Production

Time is money. While a manual worker can pack 10 bags a minute, a standard 10-Head Weigher can handle 60-70 bags per minute. A 14-Head or high-speed model can easily reach 100-120 bags per minute.

C. Versatility for “Difficult” Products

Multihead weighers aren’t just for easy-flowing rice.

• Sticky Products (Gummies/Fresh Meat): We use “Dimple Plate” surfaces (textured like a golf ball) to prevent sticking.

• Fragile Products (Biscuits): We lower the drop height and add buffer plates to prevent breakage.

• Frozen Foods: We use IP65 waterproof designs that can handle cold, damp environments.

3. Common Applications

If you produce any of the following, this machine is your standard industry requirement:

• Snack Foods: Potato chips, popcorn, nuts, seeds.

• Frozen Foods: Dumplings, nuggets, frozen vegetables, french fries.

• Confectionery: Jelly beans, chocolates, candies.

• Granules: Rice, pet food, detergents.

• Hardware: Screws, nails, plastic parts.
