Surimi Processing

When traditional surimi processing removes some water-soluble components in the surimi, it also removes some valuable insoluble components, resulting in a decrease in surimi yield. The centrifuge can recover 60-95% of the suspended solids in the surimi processing washing water and reduce the average dehydration loss by about 50%. Therefore, compared with traditional surimi processing, the advantages of centrifuges are becoming more and more obvious.

ZK SEPARATION Decanters for Surimi Processing

ZK Decanter Centrifuge has the function of continuous feeding and continuous discharging, which can make the entire surimi processing production line continuous, hygienic, and automated. Moreover, the use of centrifugal separation to replace the rotating filter and screw press used in traditional surimi processing will effectively reduce the process steps of surimi production and increase surimi yield. Moreover, in addition to strong wear resistance, the equipment is also equipped with excessive vibration protection, motor overload and overheat protection, bearing temperature monitoring, conveyor torque protection, and airtight explosion protection.
