Cleaning and sanitizing system for frozen dessert mixing machine
First Claim
1. In a frozen dessert mixing machine including a mixing auger, a motor driven system for rotating the auger, a mixing cone in coaxial alignment with the mixing auger, and drive means for moving the mixing cone in linear movement toward and away from said auger, said improvement comprisingat least one orifice in a sidewall of the mixing cone;
- andmeans for delivering a fluid through said orifice as the cone and the orifice are moved up and down adjacent to said auger to introduce said fluid into the interior of the mixing cone and to spray said fluid over the auger as the orifice moves along the axial dimension of the auger.

Abstract
Improvements are provided in machines for processing frozen comestibles of the type in which a frozen comestible is placed in a mixing cup and the mixing cup is moved toward an auger which mixes the frozen comestible into a smooth, soft material. The improvements comprise at least one orifice in a sidewall of the mixing cone and a system for delivering a cleaning and sanitizing solution through the orifice to spray the solution into the interior of the mixing cone. As the mixing cone is moved up and down, the cleaning and sanitizing solution is sprayed into the mixing cone and impinges on the auger to clean and sanitize the auger and the interior of the mixing cone. The system for delivering the cleaning and sanitizing solution preferably comprises a manifold having a hollow interior, with a plurality of orifices in the sidewall of the mixing cone which communicate with the hollow interior of the manifold. The manifold is positioned adjacent to the exterior surface of the sidewall of the mixing cone. A conduit delivers the cleaning and sanitizing solution under pressure into the hollow interior of the manifold, and the cleaning and sanitizing solution is sprayed through the orifices into the mixing cone.
