The KN-740 Vacuum Mixer is an industrial vacuum meat mixing system designed for high-capacity food processing applications.
Unlike conventional mixers, the KN-740 performs mixing under vacuum conditions, removing trapped air from meat mixtures while improving protein extraction and ingredient binding. The result is a denser product structure, enhanced elasticity, improved water retention, and more uniform seasoning distribution. Vacuum mixing is widely used in sausage, emulsified meat, and processed meat production to improve texture and product consistency.
The machine adopts a dual-shaft mixing system with forward and reverse rotation, ensuring rapid and homogeneous blending while preventing material accumulation. Its intelligent control system allows operators to adjust mixing speed, direction, and processing time according to different products.
Available in 400L and 700L capacities, the KN-740 is ideal for industrial meat processing plants, sausage manufacturers, central kitchens, and prepared food production lines.
Manufactured entirely from food-grade SUS304 stainless steel, the KN-740 combines hygienic design, heavy-duty construction, and reliable continuous operation.
