Product Overview

The Continuous Animal By-Product Rendering Cooker is intended for rendering lines that receive a steady supply of prepared animal material. Indirect steam heating transfers heat through the cooker's internal surfaces while the rotating assembly moves material through the vessel. Moisture leaves through the vapor outlet, and the cooked stream continues to downstream fat and solids separation equipment.

The cooker can be specified as part of a livestock by-product processing facility serving commercial pig farms, slaughterhouses or integrated agricultural operations. Feed preparation, steam supply, vapor treatment and the surrounding steel structure building should be planned together as one process layout.

Key Features

• Continuous feed and discharge support a stable rendering line when the incoming material is properly prepared.
• Indirect steam heating provides a controlled heat-transfer surface without mixing process steam directly into the product.
• A rotating heating and conveying assembly promotes material movement and contact with heated surfaces.
• Enclosed construction directs process vapor toward the specified condensation and odor-control system.
• Inspection access, service clearances and control interfaces can be incorporated into the project design.

Structural Components

• Cooker casing and insulated enclosure
• Steam-heated rotating shaft or rotor assembly
• Feed inlet and cooked-material discharge
• Vapor collection outlet
• Drive motor, gearbox, bearings and shaft seals
• Steam and condensate connections, instrumentation and access points

The exact rotor, heating surface and connection arrangement are confirmed during engineering.

Working Principle

Prepared animal by-products enter the cooker at a controlled rate. Steam heats the internal surfaces, which transfer heat to the moving material and evaporate part of its moisture. The rotating assembly carries and mixes the material toward the discharge. Vapor is routed to the plant's vapor-handling equipment; the cooked material then proceeds to the specified draining, pressing or fat-separation stage. Operating settings depend on the feedstock and the required downstream process.

Technical Specifications

Applications

• Meat and bone by-product rendering lines
• Pig and poultry processing by-product facilities
• Centralized rendering plants serving livestock operations
• Integrated projects requiring continuous cooking before fat and solids separation

Customization Options

Cooker sizing, feed and discharge interfaces, materials of construction, insulation, instrumentation and control integration can be specified according to project requirements. The overall arrangement can be designed according to local climate and farm conditions, available utilities and the planned rendering process.

Installation & Maintenance

Installation planning should confirm foundation loads, lifting access, service space, steam and condensate connections, vapor ducting and interfaces with upstream and downstream livestock equipment. During operation, maintenance personnel should inspect the drive, bearings, seals, steam system and access covers according to the supplied maintenance schedule. Cleaning and inspection procedures should be matched to the processed material.

Product FAQ

Does the cooker accept whole carcasses?
Feed material must be prepared to suit the selected cooker and conveying system. Required size reduction is determined during process design.

Can it be integrated into an existing rendering line?
Yes, subject to a review of the existing feed preparation, steam capacity, vapor treatment, controls and downstream separation equipment.

What information is needed for sizing?
Provide the feedstock type, expected hourly input, moisture range, operating schedule, available steam and intended downstream process.
