A Complete Guide to Multihead Weighers and Linear Weighers

Selecting the right weighing system is essential for modern automated packaging lines. Different industries handle materials with unique characteristics such as fragility, stickiness, moisture, irregular shapes, or mixed formulations, requiring specialized weighing technologies.

Two of the most widely used systems are multihead weighers (combo weighers) and linear weighers. Each solution is designed to solve different production challenges.

As a professional manufacturer of weighing and packaging equipment, TOUPACK provides customized weighing solutions for industries including fresh produce, frozen food, snacks, seafood, pet food, and prepared meals.

This guide will help you choose the most suitable weigher based on industry application, product characteristics, and production speed requirements.

Quick Industry Selection Guide

2. Frozen Food Industry

Recommended Solution: Standard Multihead Weigher

Frozen foods such as shrimp, dumplings, meatballs, and frozen vegetables require fast and stable weighing systems capable of operating in low temperatures.

A standard multihead weigher uses intelligent combination algorithms to deliver fast and precise weighing results.

Frequently Asked Questions (FAQ)

What is the difference between a multihead weigher and a linear weigher?

A multihead weigher uses multiple weighing heads to combine different weight portions automatically, achieving very high speed and accuracy.
A linear weigher uses vibration feeding and is typically better for simple or formula-based weighing applications.

Which industries commonly use multihead weighers?

Multihead weighers are widely used in industries such as:

• Snacks

• Frozen food

• Seafood

• Fresh produce

• Nuts and dried fruits

• Confectionery

These industries benefit from high-speed and high-precision weighing.

When should I choose a belt multihead weigher?

A belt multihead weigher is recommended for fragile or wet products, including:

• Fresh fruits and vegetables

• Seafood

• Delicate food items

The belt feeding system helps reduce product damage and improves handling.

How accurate is a multihead weigher?

Most modern multihead weighers can achieve very high weighing accuracy, often within 0.1–1.5 grams depending on the product and target weight.

Advanced weighing algorithms used by manufacturers like TOUPACK help minimize product giveaway.

Can TOUPACK customize weighing solutions for different industries?

Yes. TOUPACK provides customized weighing and packaging solutions based on:

• Product type

• Target weight range

• Required packaging speed

• Production line layout

This ensures that every customer receives the most efficient and reliable weighing solution.
