Abstract
Abstract Process for continuously blending temperature-sensitive ingredients, such as flour and shortening, in a mixing apparatus for the production of dough and simultaneously introducing into the dough mixture, a refrigerant or cooling medium which makes it possible to use a high proportion of shortening. The preferred cooling medium is carbon dioxide in the form of small solidified particles or snow which are introduced into the flour in the initial stages of the blending operation prior to combining of the chilled flour with the shortening. Preferably, the shortening is also subjected to a cooling operation prior to its introduction into the mixing apparatus.

Claim 3
Dependent Claim
14 words
The process of claim 1 in which the cooling substance is carbon dioxide snow.
Claim 4
Dependent Claim
37 words
