Poultry Feet Spiral Pre-Chiller

Product Overview

The machine adopts a spiral conveying structure inside a stainless steel water tank. While the spiral system moves the feet forward continuously, an air blower generates bubbles to agitate the water, ensuring uniform temperature distribution throughout the chilling tank.

The equipment is suitable for cooling:

• Chicken feet

• Duck feet

• Goose feet

It is widely used in:

• Chicken feet processing factories

• Poultry slaughterhouses

• Frozen poultry product production lines

With continuous operation, stable cooling performance and easy maintenance, the spiral feet pre‑chiller improves processing efficiency and product quality.

Working Principle

The poultry feet spiral pre‑chiller works through a combination of spiral conveying and chilled water cooling.

After scalding and cleaning, poultry feet enter the cooling tank and remain immersed in cold water.

The internal spiral conveyor slowly moves the feet through the tank, controlling the residence time during cooling.

At the same time, the air blower produces continuous airflow into the water. The generated bubbles create water movement, preventing temperature differences and ensuring that all feet receive consistent cooling.

The feeding side is equipped with an overflow structure to maintain the correct water level during continuous production.

After reaching the discharge end, cooled poultry feet are transferred to the next processing stage.

Key Performance Parameters

Application

The Poultry Feet Spiral Pre‑Chiller is mainly applied in poultry feet processing lines after scalding and cleaning.

After processing, poultry feet usually have a high temperature. The pre‑chiller reduces the product temperature before further operations such as:

• Grading

• Packing

• Freezing

• Export preparation

It is commonly used in:

• Chicken feet processing plants

• Poultry slaughterhouses

• Frozen chicken feet production factories

• Duck feet processing facilities

For export‑oriented poultry processors, effective pre‑chilling helps improve product appearance, freshness and storage quality.

Application Case

Case: Frozen Chicken Feet Processing Plant

A poultry processor producing frozen chicken feet required a continuous cooling solution after scalding.

Before installation:

• Product cooling was uneven

• Manual water cooling required more labor

• Production efficiency was limited

Huatao supplied a spiral feet pre‑chiller with:

• 304 stainless steel structure

• Air blower agitation system

• Continuous spiral conveying design

Advantages

• Effective Temperature Reduction
  Immersion cooling provides direct and efficient heat exchange.

• Uniform Cooling Performance
  Air agitation ensures consistent water temperature.

• High Production Efficiency
  Continuous operation meets industrial processing requirements.

• Durable Food Grade Design
  Fully stainless steel construction provides long service life.

• Easy Cleaning and Maintenance
  Simple structure reduces daily maintenance work.
