CMP manufactures a Mussel Declumper to separate mussels from the spat and small mussels that amass during natural growth of the mussel. This unit features a hopper and infeed conveyor. Additionally, it utilizes a paddled shaft to separate the mussels and a ring grader to filter out the debris and small mussels not suitable for packaging. The mussels are loaded into a hopper and travel on an incline conveyor that gradually feeds the Declumper. The paddled shaft within the unit moves the product and separates the mussels. It is then transferred into a ring grader that removes the separated debris and undersized mussels.
