The animal fat filling production line is a dedicated fully automated integrated system specifically designed for high-temperature, high-viscosity, easily stretchable, and rapidly solidifying oils such as lard, chicken fat, beef tallow, lamb fat, and edible animal fats. Compliant with hot-filling processes, it addresses industry challenges including oil clumping upon cooling, filament formation during filling, leakage contamination, and significant weight variations in product output. This equipment is widely adopted in food manufacturers, oil processing plants, and slaughterhouse-based deep-processing facilities for large-scale production.
