High-Temperature Rendering Machine

Product Overview

The high-temperature rendering machine is a type of high-temperature drying and rendering equipment, specifically designed for the harmless treatment of dead animals, slaughterhouse waste, and medical waste. It features a sealed, high-pressure double-layer container structure that uses circulating high-temperature steam to achieve sterilization and drying. The steam does not come into direct contact with the material, ensuring effective sterilization while preventing contamination. During operation, the core temperature of the treated material reaches ≥140℃, with a pressure of ≥0.4MPa, maintained for 30 minutes. The entire processing cycle takes only 4–6 hours, converting livestock and poultry carcasses, slaughterhouse waste, and other materials into recyclable meat and bone meal and oil. The equipment is designed and manufactured in accordance with boiler and pressure vessel standards, equipped with safety valves, pressure controllers, and other safety devices, ensuring safe and reliable operation.

Technical Principle

The high-temperature rendering machine achieves harmless treatment based on the principle of high-temperature, high-pressure sterilization: inside a sealed, high-pressure double-layer container, circulating high-temperature steam transfers heat through the container walls, raising the core temperature of the internal material to above 140℃ while maintaining a pressure of ≥0.4MPa. This process continues for at least 4 hours, followed by 30 minutes of heat preservation and pressure maintenance, thoroughly eliminating pathogens in the material and achieving a 100% sterilization rate. Subsequently, a drying process separates the treated material into meat and bone meal and oil, enabling resource recovery from waste. Throughout this process, the steam does not directly contact the material, thus avoiding damage to its components and ensuring the quality of the resulting meat and bone meal and oil.

Target Customer Groups

Harmless treatment plants for dead animals, large-scale farms, livestock and poultry slaughterhouses, animal husbandry and veterinary regulatory authorities, and medical waste treatment institutions

Application Scenarios

This equipment can be widely applied in various harmless treatment scenarios: in large farms, it handles dead pigs, cattle, chickens, rabbits, and other livestock, preventing disease spread; in slaughterhouses, it processes various types of waste generated during slaughtering, enabling resource utilization of slaughter residues; in harmless treatment plants for dead animals, it serves as the core processing unit for batch treatment of collected dead livestock and poultry from across regions; in medical waste treatment settings, it performs high-temperature sterilization of infectious medical waste, meeting safe discharge standards.

Solutions to Industry Pain Points

1. Addresses the long processing times and low efficiency of traditional methods for handling dead animals: conventional approaches often require more than ten hours, whereas this equipment completes the entire process in just 4–6 hours, greatly improving efficiency and avoiding environmental and biosecurity risks associated with waste accumulation.
2. Solves the problem of incomplete sterilization and high risk of disease transmission: traditional methods often suffer from insufficient temperature or pressure, leading to inadequate sterilization, while this equipment maintains 140℃ high temperature and 0.4MPa high pressure, achieving a 100% sterilization rate and thoroughly eliminating pathogens, thereby cutting off disease transmission routes at the source.
3. Tackles the issue of low-value, high-cost waste treatment: traditional methods mainly rely on landfilling or incineration, which are both costly and environmentally harmful, whereas this equipment converts waste into meat and bone meal and oil, enabling resource recovery, reducing treatment costs, and creating additional economic value.
4. Resolves concerns about inadequate equipment safety and compliance: some smaller treatment units are not manufactured to standards and pose safety risks, while this equipment is rigorously designed according to boiler and pressure vessel standards, fully equipped with safety devices, ensuring safe and compliant operation in line with industry regulations.
