I. Product Overview
The Screw Gizzard Chiller is a high-efficiency thermal management unit specifically designed for the byproduct processing section of a poultry slaughterhouse. It serves as a critical bridge between the peeling stage and final packaging, providing the necessary temperature reduction to inhibit microbial growth. The machine features a horizontal tank design with an internal spiral propulsion system, reflecting the latest trends in industrial automation and sanitary engineering. Its structure is optimized for high-volume processing while maintaining a compact footprint, making it an essential component for any facility aiming to achieve international food safety standards.
II. Functions & Workflow
The primary function of this machine is to rapidly remove residual heat from processed gizzards through immersion cooling. The workflow begins as gizzards are discharged from the peeling machine into the chiller’s tank, which is filled with chilled water or an ice-water mixture. An internal screw auger slowly rotates, propelled by a geared motor, to move the gizzards through the cooling medium. This constant movement, often supplemented by air agitation (bubbling), ensures uniform heat exchange and prevents the gizzards from clumping. This mechanical process solves the inefficiency of batch cooling and significantly reduces the core temperature of the product in a continuous, controlled manner, thereby protecting the texture and quality of the meat.
III. Materials & Build Quality
In adherence to the strictest food hygiene regulations, the entire Screw Gizzard Chiller, including the tank, spiral auger, and support frame, is fabricated from premium SUS304 stainless steel. This choice of material guarantees maximum resistance to the corrosive effects of blood, fats, and harsh chemical sanitizers used in slaughterhouses. The internal screw is precision-welded and polished to ensure a smooth surface that prevents bacterial buildup and allows for easy cleaning. The drive system utilizes high-quality waterproof motors and heavy-duty bearings designed for long-term reliability in high-humidity environments. All seals and non-metallic components are made from food-grade materials, ensuring a safe and durable industrial solution.

V. Capacity & Performance
Our Screw Gizzard Chiller is engineered for high-intensity, 24-hour continuous industrial operation. It offers a processing capacity of [Placeholder] kg per hour, which can be synchronized with slaughter lines running from 2,000 to 12,000 birds per hour (BPH). The residence time of the product within the cooling tank can be precisely controlled by adjusting the screw speed via a variable frequency drive (VFD). This ensures consistent performance and a low failure rate even during peak production loads. The high thermal efficiency of the immersion design results in a stable discharge temperature, effectively meeting the requirements for export-grade byproduct processing.
VI. Application Scenarios
This equipment is a standard requirement for large and medium-scale poultry slaughtering plants and specialized gizzard processing centers. It is highly versatile and can be used to cool various types of poultry byproducts, including chicken, duck, and goose gizzards. Its compact and modular design allows it to be easily integrated into existing evisceration and offal processing lines. It is particularly essential for enterprises that must comply with HACCP standards and those focused on the long-distance transport or export of fresh and frozen poultry offal products.
