A Granule Packing Machine is a set of automatic equipment. It takes loose granule materials, weighs them, fills them into bags, seals the bags, and outputs finished packages. This line works well for the food, chemical, and pharmaceutical industries.

Production Flow

  1. Manual feeding → 2. Z‑type elevator lifts material → 3. Multihead Weigher weighs → 4. Vertical packing machine makes bag and fills → 5. Sealing and coding → 6. Finished product conveyor outputs

Machine Functions and Main Parameters

1. Multihead Weigher (14-head combination scale)

Function: Automatically weighs granule materials to make sure each bag has the right weight. It uses multiple weighing buckets to find the best combination close to the target weight. Fast and accurate.

ParameterValue / Description
Weighing range10 ~ 2500g
Weighing accuracy±0.1 ~ 1.0g
Max speed120 bags/minute
Hopper capacity2.5L

Voltage220V / 50Hz
Power40W
Dimensions1600×520×1000mm

In this equipment set, the High Quality Multihead Weigher Packing Machine gets the most attention from customers, because it determines the packing accuracy and speed. If you need higher speed or a larger weighing range, we also offer the Automatic 14-head Weigher machine and the Multihead Combined Weigher.

Features Fully Automatic Granule Packing Line

High weighing accuracy
The Multihead Weigher uses high-accuracy sensors and smart combination algorithms. Weighing accuracy can reach ±0.1g. Even for granules of different sizes, each bag has the same weight.

Fast packing speed, high output
The multihead weigher runs up to 120 times per minute. Together with the vertical packing machine, the whole line runs steadily at 10–60 bags per minute. One line can produce tens of thousands of bags per day, meeting large orders.

Fully automatic, less manual work
From lifting, weighing, bag making, filling, sealing to output, the PLC controls everything automatically. Workers only need to add materials and monitor the machine.

Works with many materials
Whether you have free‑flowing materials like peanuts and rice, or fragile items like potato chips and puffed snacks, the line handles them gently. You can change the bag form to switch bag widths.

Advantages of High Quality Granule Packing Line

  1. Reduces material waste: High-accuracy weighing avoids giving extra product in each bag. For example, if you overfill 2 grams per bag and produce 50,000 bags per day, that wastes 100 kg of material per day, 3 tons per month.
  2. Flexible Productionles: Whether you need small 50g sample bags or large 25kg feed bags, you can produce them on the same line.
  3. Easy production management: The PLC automatically records output, running time, fault alarms, and more. Managers can check production data anytime. It can also connect to your factory ERP system for digital management.
  4. Safe and environmentally friendly: The equipment has safety guards and doors. Opening a door stops the machine. Low noise, no dust leakage. Meets CE and other international standards.

FAQ

Can you test my material before I buy?

Yes. You can send us your material. We will run a test and send you a full video. You can also come to our factory to see the test in person.

If I want to change my bag width later, do I need to buy a new machine?

No. You just need to buy an extra bag for the new width (about 3,000 RMB). Then we change a few settings on the packing machine.

Can this line connect to my existing downstream equipment?

Yes. Our finished product conveyor has adjustable height and speed. It can connect to your checkweigher, metal detector, cartoner, case packer, palletizer, etc.

What if the machine breaks down? How long is the warranty?

We offer a one-year warranty. During that time, we sent free replacement parts for any non-human damage
