Stainless Steel Screw Chiller System for Chicken, Duck and Turkey Slaughterhouse

Product Overview

The machine is manufactured with food‑grade 304 stainless steel, providing excellent corrosion resistance, hygienic performance and long service life in wet processing environments.

Compared with traditional open water tanks, the spiral design requires less installation space while providing longer chilling time and continuous processing capacity. It can be customized according to production requirements, including chicken, duck, goose and turkey processing lines.

The system is widely used in medium and large‑scale poultry slaughterhouses requiring stable cooling performance, improved product quality and compliance with international food safety standards.

Working Principle

The poultry carcasses enter the spiral pre‑chiller after the evisceration process.

Inside the stainless steel chilling tank, a rotating spiral screw continuously pushes the carcasses forward while they are immersed in chilled water or ice water.

At the same time, the air agitation system creates water movement around the carcasses, improving heat exchange efficiency and ensuring even cooling.

The refrigeration system maintains the water temperature within the required range. During transportation through the spiral channel, the carcass temperature gradually decreases until reaching the target cooling level before entering the next processing stage.

Application

The spiral pre‑chiller is mainly installed in the cooling section of poultry slaughtering and processing plants.

Typical applications include:

• Chicken slaughterhouses

• Duck processing factories

• Turkey processing facilities

• Frozen poultry production plants

• Fresh poultry meat processing lines

The equipment is normally positioned after:
Evisceration → Inspection → Pre‑Chilling → Cutting / Grading → Packaging

For frozen poultry products, water chilling is widely used because it provides fast cooling efficiency and stable production speed. Air chilling systems are also used for certain fresh poultry products where lower water absorption is required.

Application Case

Case 1: 8,000 BPH Chicken Processing Plant – Southeast Asia

A poultry processing factory required a continuous cooling system for its automatic chicken slaughter line.

Project Requirements:

• Production capacity: 8,000 birds/hour

• Limited installation space

• Stable carcass temperature control

• Easy cleaning and maintenance

Solution:

A customized spiral pre‑chiller system with SUS304 stainless steel structure was installed after the evisceration line.

Case 2: Duck Processing Factory – Middle East Market

The customer needed equipment suitable for high‑temperature environments and long working hours.

Customized solution included:

• Heavy‑duty stainless steel structure

• Enlarged cooling tank capacity

• Adjustable screw speed control

The system successfully integrated with the existing duck processing line.
