Abstract

An ice-grinding device comprising a top cover, a helical pressing core, a disk cutter and container, whereby the disk cutter is mountable on the container, the helical pressing core is locatable within the disk cutter, the top cover is mountable on the disk cutter so as to engage the helical pressing core and it is also directly mountable on the container. The ice-grinding device may include means to control the fineness of the processed ice particles. The ice-grinding device may be adapted to process food.

Claims

5-1. An ice-grinding device as claimed in claim 5, wherein the blade plate includes:

a plurality of pressure plates fixed on a plate and

a plurality of blades with different rakes,

whereby a blade is mounted on an upperside of each of the pressure plates and the blade plate co-operates with the blade-selecting means and blade-locking device.

6. An ice-grinding device as claimed in claim 6, wherein the blade-selecting means includes

a blade-selecting tab formed on the plate of the blade plate and arranged so that the plate can be moved so the selected blade is positioned adjacent the opening in the disk cutter.

8. An ice-grinding device as claimed in claim 7, wherein the blade-locking device includes:

an elongate shaft,

a small cylindrical portion,

a joining part and

a blade-locking handle that are arranged so that when the blade-locking handle is rotated the elongate shaft applies pressure to the pressure plate of the selected blade to force the selected blade through the opening in the disk cutter.
