## Abstract

A system for automatically rapidly chilling liquids and semisolids which includes a frame which supports a drive motor which contains a substantially vertical drive shaft having a connecting member at one end. A sealed, hollow chilling utensil which contains a refrigerant, and which has a neck portion which contains a connecting member which is adapted for fixed engagement with the connecting member of the drive shaft.

## Claims

### Claim 1

A system for automatically rapidly chilling liquids and semisolids which comprises:
(a) a support frame which includes a drive motor which contains a substantially vertical drive shaft having a connecting member at its distal end; and
(b) a sealed hollow chilling utensil which contains a cold refrigerant having a neck portion which contains a connecting member which is adapted for fixed engagement with the connecting member of said drive shaft such that immersing the chilling utensil into a food product and rotating the chilling utensil rapidly cools the food product.

### Claim 2 (depends on 1)

The system of claim 1 in which the connecting member of the chilling utensil comprises a threaded cap which contains connecting means at its top surface.

### Claim 3 (depends on 2)

The system of claim 2 in which connecting means comprises a slot which is adapted to receive a locking member contained on the distal end of the drive shaft.

### Claim 4

A method for automatically rapidly chilling liquids and semisolids which comprises:
(a) providing a frame which supports a motor which contains a drive shaft having a connecting member at its distal end;
(b) connecting a sealed hollow elongated chilling utensil containing a refrigerant to the connecting member of said drive shaft;
(c) immersing said chilling utensil into a food product to be cooled; and
(d) rotating said chilling utensil on said drive shaft for a time sufficient to rapidly cool said food product to a desired predetermined temperature.
