High-Moisture Brown Sugar Packing Machine with 14-Head Screw Feeding Multihead Weigher

Videos

Industry Challenge: High-Moisture Sugar Packaging

Brown sugar with elevated moisture content typically shows:

• Poor flowability

• Strong adhesion to surfaces

• Irregular feeding behavior

• Hopper bridging and material buildup

Why Standard Multihead Weighers Fail

Traditional multihead weighers rely on:

• Vibration feeding

• Gravity flow

For sticky sugar, this leads to:

• Uneven distribution into weighing hoppers

• Empty or overloaded buckets

• Unstable combination accuracy

• Frequent cleaning and downtime

Core Solution: 14-Head Screw Feeding Multihead Weigher

This system upgrades the feeding mechanism of a standard multihead weigher:

Replacing vibration feeding with screw-controlled feeding for each channel

How It Works

• Each feeding lane is equipped with a screw feeder

• Material is actively pushed forward, not relying on gravity

• Sugar is evenly delivered into each weighing hopper

• The system still performs multihead combination weighing for final accuracy

Technical Advantages

1. Stable Feeding for Sticky Materials

• Eliminates bridging and arching

• Ensures consistent material supply to each head

• Reduces empty hopper issues

2. Maintains Multihead Accuracy

• Retains combination weighing logic

• Improves weight consistency under unstable flow conditions

• Typical accuracy: ±3–5g (250g–1kg range)

3. Reduced Material Adhesion

• Controlled feeding reduces random sticking

• Optional anti-stick surface treatment

• Cleaner operation over long runs

FAQ

1. What is the key difference from standard multihead weigher?

Standard systems rely on vibration. This machine uses screw feeding, ensuring stable material flow for sticky sugar.

2. Is it necessary for all sugar products?

No. It is mainly required for:

• High moisture

• Sticky

• Poor flowability

Dry sugar can use standard multihead weigher.

3. Will this affect speed?

Slightly lower than standard multihead, but:
much higher stability and consistency

4. Does it solve material sticking completely?

It significantly reduces feeding issues and improves consistency, but extremely sticky products may still require:

• Coating

• Agitation

5. Can it be upgraded to a full line?

Yes, it can connect to:

• Feeding systems

• Secondary packaging (cartoning / bagging)

Conclusion

For high-moisture brown sugar, packaging stability depends on feeding control, not just weighing.

The 14-head screw feeding multihead weigher provides:

• Stable material flow

• Reliable weighing accuracy

• Reduced downtime

making it a specialized and high-performance solution for sticky granular products.
