The hydraulic tumbler can evenly distribute marinade throughout the meat, enhancing its binding capacity and the product's elasticity. It improves the texture and cross-sectional appearance of the product, increases water retention, boosts yield, and refines the internal structure of the product, all while being energy-efficient and highly effective. The entire machine is constructed from stainless steel, featuring a compact design. Both ends of the drum utilize a spin-sealed cap structure, maximizing the tumbling space inside the drum to ensure uniform marination of the product. It operates with low noise, reliable performance, simple operation, and high efficiency.
