The fish material enters the fish cutting crusher through the storage bin. The fish cutting crusher can crush and refine the larger fish and fish head to get the block size ≤5cm, so as to improve the processing efficiency of post-curing and sterilization. The machine is uniaxial structure, gear cutter adopts wear-resistant alloy steel 40Cr, rotary gear cutter and anvil grid section are hardened surface treatment, hard and wear-resistant. The frame is made of Q235 carbon steel, the shell is made of 304 stainless steel, and the upper cover is opened and closed by pneumatic control. Low noise, high crushing efficiency, automatic cleaning, closed machine, can effectively avoid environmental pollution. Using outer jacket and spindle coil or steam box through steam, increase the heating area, its structure and working principle determines that it has high thermal efficiency, low energy consumption, easy operation and control, good operating environment and so on. Exhaust hood, pipe made of stainless steel, improve corrosion resistance, prolong the service life. Using the automatic water delivery system, the steam condensate will be recycled to the boiler to reduce energy consumption and save water. It is suitable for fish meal processing and has been applied and recognized by more and more fish processing enterprises.
