1. Core Raw Materials
- Source: Poultry-derived fats (chicken/duck/goose abdominal fat, subcutaneous fat)
- Origin: Slaughterhouse by-products (qualified suppliers, traceable source)
- Features: Abundant supply, cost-effective, high fat content
2. Equipment Specifications
The system is designed with fully automated operations including feeding, slag discharge, and oil-residue separation, ensuring simple operation and compliance with environmental standards.
When animal adipose tissue is heated and melted, oil is released from it.
Under the effect of heat, the oil in animal fat cells transitions from a solid to a liquid state. Heating animal fat reduces the viscosity of the oil and lowers its surface tension. This is the result of thermal molecular motion and the weakening of intermolecular cohesion. The reduction in cohesion makes it easier for the oil to separate from the cells and allows the oil droplets from individual cells to coalesce into larger masses. Simultaneously, due to differences in specific gravity, the oil separates from the protein.
3. Rendering Process
- Melting is conducted under vacuum, which removes moisture from the raw materials, yielding dry oil and dry oil residue.
- As the equipment is sealed, the entire melting process avoids any adverse effects of air oxidation on the oil, such as an increase in peroxide value and darkening of color.
- It ensures the production of high-quality oil, as organic substances that enhance the edible value and storage stability of the oil (such as vitamins, stearyl alcohol, lecithin, etc.) are preserved.
- The oil undergoes partial deodorization while also eliminating unpleasant off-flavors.
- High-quality oil residue is obtained, as the proteins remain largely undenatured due to the vacuum melting process.
- Thermal energy loss during the melting process is reduced.
