12-Head vs 16-Head vs 20-Head vs 26-Head Combination Weigher: How to Choose?
Choosing the right combination weigher is an important decision for food processing companies. Different products, target weights, and production capacities require different machine configurations.
Among the most common options are 12-head, 16-head, 20-head, and 26-head combination weighers.
The number of weighing heads affects weighing flexibility, accuracy, production speed, and application range.
This guide explains the differences between different combination weigher models and helps food manufacturers select the right solution for their production needs.
What Does the Number of Heads Mean in a Combination Weigher?
A combination weigher, also known as a multihead weigher, uses multiple weighing units to calculate the best weight combination.
The number of heads refers to the number of independent weighing units installed in the machine.
More weighing heads provide more possible combinations, which can improve weighing accuracy and production flexibility.
However, the best choice is not always the machine with the most heads. The right configuration depends on:
- Product characteristics
- Target package weight
- Required production speed
- Factory automation requirements
12-Head Combination Weigher
A 12-head combination weigher is a practical solution for standard food weighing applications.
It is suitable for manufacturers who need reliable automatic weighing with a cost-effective investment.
Common applications include:
- Frozen food
- Vegetables
- Seafood products
- Standard portion packaging
Advantages:
- Stable weighing performance
- Good accuracy
- Suitable for medium production requirements
- Cost-effective solution
A 12-head model is often a good choice for companies starting food weighing automation.
16-Head Combination Weigher
A 16-head combination weigher is one of the most widely used configurations in food processing industries.
Compared with a 12-head model, it provides more weighing combinations and improved flexibility.
Suitable applications include:
- Seafood processing
- Frozen products
- Meat products
- Fruit and vegetable packaging
Advantages:
- Better weighing accuracy
- Higher production efficiency
- Flexible application range
- Good balance between performance and investment
For many food factories, a 16-head combination weigher is an ideal solution for daily production.
20-Head Combination Weigher
A 20-head combination weigher is designed for applications requiring higher production capacity and more accurate portion control.
With more weighing units, the system can calculate more possible combinations to achieve the target weight.
Suitable applications include:
- High-speed packaging lines
- Large food production factories
- Products requiring strict weight control
Advantages:
- More weighing combinations
- Higher production flexibility
- Improved weighing accuracy
- Suitable for continuous operation
26-Head Combination Weigher
A 26-head combination weigher is designed for demanding production environments that require maximum weighing flexibility and efficiency.
With more weighing units, it can handle complex weighing requirements and high-volume production.
Common applications include:
- Large seafood processing plants
- Frozen food factories
- High-speed packaging lines
- Large-scale food production
Advantages:
- Excellent combination capability
- Higher production efficiency
- Suitable for high-output factories
- Advanced automation performance
12 Head vs 16 Head vs 20 Head vs 26 Head Combination Weigher Comparison
| Model | Suitable For | Main Advantages |
|---|---|---|
| 12 Head | Standard production | Stable and economical |
| 16 Head | Medium and high-speed production | Balanced performance |
| 20 Head | Higher capacity production | More weighing combinations |
| 26 Head | Large-scale production | Maximum flexibility and efficiency |
