Automatic Hot Water Scalding Machine for Chicken, Duck & Goose Slaughterhouse

Product Overview

Compared with traditional manual scalding methods, an automatic poultry scalder provides:

• More stable scalding performance

• Better feather removal results

• Higher production efficiency

• Improved hygiene control

The machine is widely used in:

• Chicken slaughterhouses

• Duck processing plants

• Goose processing factories

• Integrated poultry processing projects

A complete poultry processing line usually combines the scalder with:

• Stunning machine

• Killing system

• Bleeding trough

• Poultry plucker

• Evisceration equipment

• Chilling system

Working Principle

The poultry scalder works by immersing slaughtered birds into a temperature-controlled hot water tank.

Birds hanging on the overhead conveyor enter the scalding tank and remain submerged for a controlled period. The heated water transfers thermal energy to the skin and feather follicles, weakening the connection between feathers and the carcass.

Inside the tank, water circulation or air agitation helps maintain a uniform temperature and improves heat transfer around the entire bird.

After completing the scalding process, carcasses move directly to the defeathering machine where feathers can be removed more effectively.

The scalding temperature and time can be adjusted according to:

• Bird species

• Bird size

• Production speed

• Final product requirements

Different scalding methods are selected depending on processing requirements. Soft scalding is commonly used when skin quality needs to be maintained, while higher-temperature scalding improves feather removal efficiency.

Main Features

1. Stable Temperature Control System

The machine is equipped with a temperature monitoring system to maintain stable water conditions during continuous production.

Benefits:

• Uniform scalding effect

• Reduced production fluctuation

• Better plucking performance

2. Stainless Steel Hygienic Structure

The complete machine is manufactured with food-grade stainless steel.

Advantages:

• Corrosion resistance

• Easy cleaning

• Suitable for wet processing environments

• Long service life

3. Continuous Automatic Operation

The scalder is designed to connect with automatic poultry slaughter lines.

It supports:

• Continuous bird transportation

• Stable processing speed

• Reduced manual operation

4. Efficient Water Circulation Design

The internal circulation system helps maintain consistent temperature distribution throughout the tank.

Benefits:

• Better heat transfer

• Reduced temperature difference

• Improved scalding quality

5. Adjustable Scalding Parameters

Operators can adjust:

• Water temperature

• Processing time

• Conveyor speed

according to different poultry requirements.

6. Easy Connection with Plucking Equipment

The scalder is normally installed before:

• Vertical plucker

• Horizontal plucker

• Automatic defeathering system

to create a complete feather removal section.

Technical Specifications

Application

Chicken Processing Plants

The poultry scalder is mainly installed after the bleeding section and before the defeathering machine in commercial chicken processing plants.

For high-speed broiler processing lines, stable scalding is critical because uneven feather loosening can affect plucking performance and carcass appearance.

Duck and Goose Processing Facilities

Waterfowl usually have stronger feather attachment compared with chickens.

The scalder can be adjusted with suitable temperature and processing time to achieve better feather removal results while protecting carcass quality.

Large Poultry Slaughterhouses

In large automated processing facilities, the scalder works as part of the complete slaughter line.

It connects with:

• Live bird handling system

• Killing equipment

• Bleeding system

• Plucking machines

• Evisceration line

to provide continuous processing.

Poultry Processing Projects

For new slaughterhouse construction projects, the scalder can be customized according to:

• Production capacity

• Factory layout

• Bird type

• Automation requirements

Application Case

Case 1: Chicken Processing Plant Feather Removal Improvement

A chicken processing company experienced unstable feather removal results due to inconsistent manual scalding.

The factory installed an automatic poultry scalder connected with the existing overhead conveyor system.

Case 2: New Duck Processing Line Installation

A duck processing factory required equipment suitable for continuous production.

The customized scalder was integrated with:

• Duck slaughter line

• Defeathering equipment

• Carcass washing system

The solution improved production flow and reduced manual intervention.

Advantages

• Improve Feather Removal Efficiency
  Proper scalding helps loosen feathers and improves downstream plucking performance.

• Stable Processing Quality
  Automatic temperature control provides consistent results during long production hours.

• Reduce Labor Requirement
  Continuous operation reduces dependence on manual scalding operations.

• Durable for Industrial Use
  Stainless steel construction provides reliable performance in demanding slaughterhouse environments.

• Flexible Production Solutions
  The machine can be customized for different bird types and production capacities.
