Abstract
In an ice disaggregation system employing teeth affixed to a bracket which is spirally disposed around the outer periphery of a cylindrical rotating drum and held in spaced relationship therefrom, the cutting capacity is improved by tilting the plane of each tooth with respect to the drum's axis of rotation such that each incremental section of ice which a tooth engages is subjected to a bending force about a pivot near an area from which ice has been removed and is therefore relatively weak. As a result, the ice readily fractures in relatively large chunks.
