High-speed Rotary GraderMarunushi Co.,Ltd.

Space-saving realize the high-speed multistage sorting of marine products

In 2011, fishing ports and seafood processors across the northeast Pacific coast were devastated by the Great East Japan Earthquake. In the reconstruction efforts after the disaster, many of our customers requested the development of an “automatic selector” that is space-saving, easily movable, and able to grade fresh fish at high speed and accuracy. Their eagerness became the driving force behind our sales and technical departments and resulted in the introduction of our new Rotary Grader in the market. The new Rotary Grader is capable of weighing and grading up to 350 freshly landed saury (sanma) and 250 mackerel (saba) every minute by utilizing the fast rotation measurement method. This device incorporates the scale hopper method, can handle different types of fish and remain useful as “a year-round grader” , unlike existing models. Since its market launch, the machine has been selected by many customers and busy operating at various sorting factories.
