Abstract
The apparatus comprises an enclosure for receiving ice chips and water and a specially designed and dimensioned mixer in the form of a vertical shaft passing into the enclosure and supporting two sets of four turbine blades each. Further, the interior of the enclosure includes baffles spaced radially inwardly from the interior wall to leave a small gap between the wall and each baffle. The resulting violent agitation enables the provision of "liquid ice" without any necessity to add salt as has been required in the past.
