Abstract
Abstract An in-place cleaning and sanitizing system for a frozen confection machine. A wash head is extended over the storage hopper of the machine and liquid and a cleansing agent are introduced into the wash head. A cleaning solution is dispensed from the wash head into the storage hopper, and then into the freeze chamber of the machine, where it cleans and sanitizes the hopper, freeze chamber and all surfaces coming into contact with the frozen confection material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
183 words
In a semi-frozen confection machine provided with a: freeze chamber adapted to freeze liquid confection material; a storage hopper communicating with said freeze chamber and adapted to contain and supply liquid confection material to the freeze chamber; a rotary beater in the freeze chamber to rotatably stir liquid material therein; an outlet valve connected to the freeze chamber for discharging liquid material therefrom; and a drive motor for rotating the rotary beater in the freeze chamber; the improvement of a cleaning system for the machine comprising: a wash head a connector at the storage hopper adapted to receive said wash head conduit means for supplying liquid to said wash head through said connector a control valve for said conduit operative between an open position and a closed position to control the flow of said liquid to said wash head; and means for operating the drive motor and operating the control valve to said open position, whereby said wash head and the rotary beaters are activated simultaneously as said liquid is dispensed from said wash head into said hopper and to said freeze chamber.
Claim 2
Dependent Claim
183 words
In a semi-frozen confection machine provided with a: freeze chamber adapted to freeze liquid confection material; a storage hopper communicating with said freeze chamber and adapted to contain and supply liquid confection material to the freeze chamber; a rotary beater in the freeze chamber to rotatably stir liquid material therein; an outlet valve connected to the freeze chamber for discharging liquid material therefrom; and a drive motor for rotating the rotary beater in the freeze chamber; the improvement of a cleaning system for the machine comprising: a wash head a connector at the storage hopper adapted to receive said wash head conduit means for supplying liquid to said wash head through said connector a control valve for said conduit operative between an open position and a closed position to control the flow of said liquid to said wash head; and means for operating the drive motor and operating the control valve to said open position, whereby said wash head and the rotary beaters are activated simultaneously as said liquid is dispensed from said wash head into said hopper and to said freeze chamber.
Claim 3
Dependent Claim
26 words
The semi-frozen confection machine of claim 1 wherein said wash head includes: means for adding a cleaning agent to the liquid flowing through said wash head.
Claim 4
Dependent Claim
38 words
The semi-frozen confection machine of claim 2 wherein said means for adding a cleaning agent includes porous container means disposed in a chamber in said wash head and in contact with the liquid flowing through said wash head.
Claim 5
Dependent Claim
53 words
The semi-frozen confection machine of claim 3 wherein said porous container means is removably disposed in said wash head, and said wash head includes removable cap means forming part of said chamber whereby said porous container means is adapted to be installed in or removed from said chamber by removing said cap means.
Claim 6
Dependent Claim
32 words
The semi-frozen confection machine of claim 2 whereby rotation of said rotary beater mixes said fluid and said cleansing agent in said freeze chamber and causes said freeze chamber to be cleaned.
Claim 7
Dependent Claim
97 words
The semi-frozen confection machine of claim 1 whereIn said wash head includes: annular spray means rotatably attached to said wash head; cavity means internally disposed in said annular spray means, port means in said wash head in communication with said cavity means adapted to transmit said liquid to said cavity from said liquid supply; aperture means angularly disposed in said annular spray means in communication with said cavity and adapted to permit the flow of liquid from said cavity, whereby the force of liquid being dispensed through said angular apertures causes said annular spray means to rotate.
Claim 8
Dependent Claim
23 words
The semi-frozen confection machine of claim 1 wherein said liquid is supplied at a temperature above the melting point of said confection material.
