Pressing Screw Thread Structure for Slice Height and Feed Control

The pressing screw is segmented into distinct functional zones: upper leading edges for cutting, intermediate support surfaces for positioning, and lower lateral cavities for collection. This segmentation allows each zone to perform its specific function optimally, with the support surfaces providing precise cutting height control while the leading edges maintain cutting capacity.

The intermediate support surfaces act as intermediaries between the upper leading edges and the lower lateral cavities. These surfaces provide a controlled transition zone that mediates the food items from the cutting action to the collection area, enabling precise control over cutting height and feeding rate while maintaining efficient cutting.

The lower lateral cavities are positioned to receive food items before they can jam between the threads. The cavities act as pre-positioned collection zones that capture cut food items, preventing them from interfering with the continuous cutting and feeding operation, thus maintaining high feeding rates without jamming.

The design converts the potential harmful effect of cut food items (which could cause jamming) into a beneficial feature by directing them into the lower lateral cavities. These cavities serve as dedicated collection zones that transform the jamming risk into an organized collection system, enabling continuous high-speed operation.
