Abstract
Abstract A process for preparing edible, fat-containing food products is disclosed wherein the dry ingredients of the food product are intimately mixed with a solid, particulate refrigeration agent until the food product has been chilled and refrigerated to a degree sufficient to recover a dry, granular, free-flowing, fat-containing food product therefrom. Dry ice is used in pellet form as the refrigeration agent, and it chills the fat-containing food products without freezing it. This aids in mixing of the fat of the food.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
In the process of preparing a dry, substantially powdery, edible, fat-containing product by mixing together fat plus the other ingredients of said product to form a mixture thereof and subsequently recovering the finished product, the improvement comprising adding, during the mixing of the ingredients and the fat, solid particles of dry ice of geometrically uniform shape and size, and particles having a diameter of about 2 mm.-15 mm. and a length of about 10 mm.-40 mm. said particles being added in an amount such as to lower the temperature of the mixture without freezing said mixture during mixing to such an extent as to render the entire mixture free-flowing and homogeneous.
Claim 2
Dependent Claim
111 words
In the process of preparing a dry, substantially powdery, edible, fat-containing product by mixing together fat plus the other ingredients of said product to form a mixture thereof and subsequently recovering the finished product, the improvement comprising adding, during the mixing of the ingredients and the fat, solid particles of dry ice of geometrically uniform shape and size, and particles having a diameter of about 2 mm.-15 mm. and a length of about 10 mm.-40 mm. said particles being added in an amount such as to lower the temperature of the mixture without freezing said mixture during mixing to such an extent as to render the entire mixture free-flowing and homogeneous.
Claim 3
Dependent Claim
22 words
The process of claim 1 wherein said dry ice particles are in the form of pellets prepared by extrusion of carbonic snow.
Claim 4
Dependent Claim
34 words
The process of claim 1 wherein the gaseous CO 2 emitted upon the sublimation of the dry ice particles is retained in the mixing vessel to serve as a protective gas during the mixing.
Claim 5
Dependent Claim
19 words
The process of claim 1 wherein immediately upon recovery the finished product is compressed into portions of pre-determined size.
