Automatic Food Checkweigher for Poultry Processing Line

Product Overview

Unlike traditional manual weighing methods, this automatic system performs continuous weight inspection without interrupting production. Each product passes through the weighing section individually, and the system compares the measured weight with preset limits.

When a product does not meet the required weight range, the automatic reject device removes it from the production line. This helps food processors reduce product giveaway, improve packaging accuracy, and maintain consistent product quality.

The machine is suitable for chicken products, frozen poultry, meat packages, ready‑to‑eat foods, and other packaged food applications. Industrial checkweighers are commonly integrated into high‑speed production lines to provide 100% online weight verification.

Working Principle

The Automatic Food Checkweigher operates through a conveyor‑based dynamic weighing system.

Products enter the machine through the infeed conveyor and are separated at a controlled distance to ensure stable weighing conditions.

When the product reaches the weighing conveyor, the high‑precision load cell measures its actual weight while the product continues moving.

The control system compares the measured weight with the preset upper and lower limits. If the product weight is within the acceptable range, it continues to the next production stage.

If the product is overweight or underweight, the system activates the rejection mechanism, such as an air blast, push arm, or swing gate, to automatically remove the non‑qualified product.

The complete weighing, judgment, and rejection process is completed automatically without stopping the production line.

Application

The Automatic Food Checkweigher is widely used in poultry processing factories and food production lines requiring strict weight control.

Typical applications include:

Poultry Processing

• Whole chicken packages

• Chicken breast packages

• Chicken wings

• Chicken legs

• Frozen chicken products

Meat Processing

• Beef packages

• Pork products

• Sausage products

Food Packaging

• Frozen food

• Ready meals

• Retail food packages

• Export food products

For poultry processing plants, the checkweigher is usually installed after packing or before final shipment inspection to ensure every package complies with customer requirements.

Application Case

Case 1: Frozen Chicken Export Factory – Southeast Asia

A frozen poultry exporter needed to improve package weight consistency before international shipment.

Before installation:

• Operators manually checked package weights

• Production speed was limited

• Weight errors occurred frequently

After installing the automatic food checkweigher:

• Every package was inspected automatically

• Underweight products were removed immediately

• Packing accuracy improved

• Labor requirements were reduced

The system was integrated with the existing conveyor packing line.

Case 2: Chicken Portion Processing Plant – Middle East

A poultry processing company supplied different retail packages with strict weight requirements.

The checkweigher helped the factory:

• Maintain accurate package weights

• Reduce overweight product loss

• Improve production data management

• Increase customer satisfaction
