For mashing potatoes, Innotec Systems has among other things pureer screws in its program. The puree screws are used to purge the steamed potato slices immediately after the steaming. The puree screw is generally mounted directly on the output of a screw or beltdrive. The steamed potato slices are pushed through a grid in the puree screw to reduce the potato parts substantially to puree.
The puree screws are cleaned and easy to clean. Various capacities and designs are available.
