Abstract
A system includes a pump device for producing a mixture product, a casing having a concealed cavity for receiving the mixture product via the pump device; and a clutch unit operatively linked to the pump device for controllably maintaining an interior pressure of the concealed cavity at a predetermined threshold. Accordingly, the pump device is activated by the clutch unit for delivering the mixture product into the concealed cavity through an inlet of the casing until the interior pressure of the concealed cavity reaches the predetermined threshold and is deactivated by the clutch unit for stop delivering the mixture product into the concealed cavity when the interior pressure of the concealed cavity reaches the predetermined threshold.
Claims20
A system for a frozen product machine, comprising:
- a pump device for mixing liquid mixture with air to produce a mixture product;
- a casing having a concealed cavity, an inlet for allowing said mixture product to be input into said concealed cavity via said pump device, and an outlet for dispensing said mixture product from said concealed cavity;
- and
- a clutch unit operatively linked to said pump device for controllably maintaining an interior pressure of said concealed cavity at a predetermined threshold, wherein said pump device is activated by said clutch unit for delivering said mixture product into said concealed cavity through said inlet until said interior pressure of said concealed cavity reaches said predetermined threshold and is deactivated by said clutch unit for stop delivering said mixture product into said concealed cavity when said interior pressure of said concealed cavity reaches said predetermined threshold.
A method of making frozen product, comprising the steps of:
- (a) activating a pump device by a clutch unit for delivering a mixture product into a concealed cavity of a casing through an inlet thereof, so as to increase an interior pressure of said concealed cavity;
- and
- (b) deactivating said pump device by said clutch for stop delivering said mixture product into said concealed cavity when said interior pressure of said concealed cavity reaches a predetermined threshold so as to controllably maintain said interior pressure of said concealed cavity at said predetermined threshold.
