Product Description
The oil melting equipment is a high-temperature, high-pressure, enclosed melting device specifically designed by our company for animal oil extraction, harmless treatment of diseased and dead livestock and poultry, and resource utilization of slaughter waste. It adopts the core process of high-temperature and high-pressure sterilization + vacuum melting + oil-water separation. While completely eliminating pathogenic microorganisms, it efficiently extracts industrial/feed-grade pure oil, achieving an integrated treatment of harmlessness, reduction, and resource utilization. It is widely used in animal husbandry, slaughtering, feed, organic fertilizer, and environmental protection treatment centers.
Main Purpose
1. Efficient melting and extraction of animal fats involves high-temperature melting of animal viscera, adipose tissue, slaughter by-products, and carcasses of diseased or dead livestock and poultry, followed by separation and extraction of industrial fats and feed-grade fats.
2. High-temperature and high-pressure sterilization and harmlessness treatment kills pathogens such as bacteria, viruses, insect eggs, and mold in a sealed high-pressure environment, fully meeting the requirements of epidemic prevention and environmental safety.
3. Solid-oil-water three-phase separation and recovery automatically achieves the separation of solid, oil, and water phases. The oil can be sold, the waste residue can be used as protein raw material and organic fertilizer raw material, and the wastewater can be purified and recycled.
4. High-value utilization of waste transforms traditional perishable and odoriferous organic waste into high-value products, eliminating pollution, increasing revenue, and achieving closed-loop processing.
Working Principle
The equipment is centered around high-temperature and high-pressure sterilization and melting, operating in a fully enclosed and automated manner throughout the entire process:
1. Feeding and sealing: Materials are fed into a sealed smelting tank, which is automatically sealed and locked, ensuring no leakage and no odor.
2. High-temperature and high-pressure sterilization and melting: Indirect heating is achieved by introducing high-temperature and high-pressure steam. Under the set pressure and temperature, sterilization, ripening, fat breaking, and melting are carried out to fully melt and separate the fat.
3. Vacuum dehydration and degreasing: Further dehydration and degreasing under negative pressure to enhance the purity of the oil and the dryness of the waste residue.
4. Oil-water separation: The mixed oil produced during melting enters the separation system, where it automatically stratifies to obtain pure oil.
5. Waste residue discharge: After dehydration and defatting, the waste residue is dry and sterile, and can be directly used as protein raw material/organic fertilizer raw material.
6. Exhaust gas purification: The exhaust gas inside the tank is uniformly collected and treated, ensuring emissions meet standards, without any odor or secondary pollution.
Equipment Advantages
The sterilization process is thorough, safe, and compliant with national harmless standards, utilizing high-temperature and high-pressure techniques to eliminate all pathogens, ensuring no biological safety risks.
2. High oil yield, pure and fully refined oil, thorough separation, good oil color, less impurities, and high market value.
3. Fully enclosed, odor-free, environmentally compliant, and operating under negative pressure throughout the entire process, with centralized odor treatment, no leachate, no dust, and no odor diffusion.
4. High automation, stable operation, PLC intelligent control, automatic temperature control, pressure control, timing, and material discharge, reducing labor, ensuring reliable continuous operation.
5. Energy saving and consumption reduction, simple maintenance, indirect heating and waste heat recovery, low energy consumption; corrosion-resistant and wear-resistant tank body, long service life.
6. Versatile and widely applicable, it can simultaneously perform sterilization, melting, dehydration, degreasing, and separation, satisfying all processing needs with just one set of equipment.
7. High resource utilization rate, significant benefits, both oil and residue can be sold, with outstanding economic benefits, significantly reducing processing costs.
Scope of Application
1. Harmless treatment center for dead livestock and poultry
2. Waste disposal in slaughterhouses/meat processing enterprises
3. Animal fat refining plants and feed processing plants
4. Centralized processing stations for livestock farms and breeding groups

What is the high-temperature incineration/wetting process of the equipment for harmless treatment of animal carcasses?
This process is currently the mainstream and compliant method for the harmless disposal of livestock and diseased animals. Its core relies on high-temperature, high-pressure saturated steam to achieve sterilization, maturation, oil-water separation, and material reduction. The entire process is sealed, meeting epidemic prevention and environmental protection standards.
Is it a manufacturer or a trader? Do they have any relevant qualification certifications?
As a national high-tech enterprise, the company specializes in the design, R&D and construction of equipment and projects related to harmless disposal and resource utilization of organic wastes.
Can the kitchen waste disposal equipment be customized?
Support customization. You can customize the equipment specifications (size, power), materials, and the degree of automation (semi-automatic/fully automatic) according to your production requirements.
