Automatic Arm Type Poultry Weight Grading Machine

Product Overview

Traditional manual sorting requires significant labor and may result in inconsistent product weight. This automatic weight grader combines high‑precision weighing technology with mechanical arm sorting to achieve continuous online grading.

The system automatically weighs each product while moving on the conveyor, compares the measured value with preset weight ranges, and activates the corresponding sorting arm to push the product into the correct collection area.

The arm‑type sorting mechanism provides gentle product handling, making it suitable for fresh and frozen poultry products where appearance and product integrity are important.

The equipment can be integrated with poultry cut‑up lines, conveyors, packing machines, and quality inspection systems to create a complete automated processing solution.

Automatic weighing and grading systems are widely used in poultry plants to improve order accuracy, reduce product giveaway, and optimize production efficiency.

Working Principle

The Arm Type Poultry Weight Grading Machine operates through a combination of conveyor transportation, dynamic weighing, and mechanical sorting.

First, poultry products are placed onto the infeed conveyor and transported individually through the weighing section.

The high‑precision weighing sensor detects the weight of each product during movement and sends the data to the control system.

The PLC controller compares the measured weight with preset grading parameters.

According to the selected weight range, the corresponding pneumatic or electric arm mechanism moves at the correct position and gently pushes the product into the designated outlet or collection box.

The entire process runs automatically, allowing continuous grading without stopping the production line.

Application Case

Case 1: Chicken Wing Processing Plant – Southeast Asia

A poultry processing factory supplied different chicken wing specifications to supermarkets and food service customers.

Before installation:

• Workers manually sorted products

• Production speed was limited

• Weight consistency was difficult to maintain

After installing the arm type weight grader:

• Chicken wings were automatically classified by weight

• Packing efficiency increased

• Labor requirements decreased

• Product specification accuracy improved

Case 2: Frozen Poultry Export Factory – Middle East

A frozen chicken supplier needed multiple weight categories for different export markets.

The grading machine helped the factory:

• Automatically separate products according to customer requirements

• Improve packing efficiency

• Reduce product weight deviation

• Increase production management capability

Advantages

• Accurate Weight Classification
  High precision weighing ensures reliable grading results.

• Reduce Labor Cost
  Automatic sorting replaces repetitive manual operation.

• Improve Packing Efficiency
  Products are automatically prepared according to weight requirements.

• Gentle Product Handling
  Arm‑type sorting reduces damage to poultry products.

• Flexible Production Solution
  Suitable for different poultry products and processing capacities.

• Better Production Management
  Weight data helps factories optimize production planning.
