ABSTRACT:
The device utilizes a helical screw for making cream from a precursor mixture of milk and butter. The screw has a first portion which continuously agitates the milk and butter mixture to prevent it from separating into its milk and butter constituents. The agitating portion also operates to feed the mixture toward the second portion of the screw which is a compression portion. The compression portion of the screw compresses and emulsifies the mixture to convert the milk and butter mixture into cream by forcing the mixture through one or more restricted orifices. The mixture is heated during agitation and compression to temperatures in the range of about 105.degree. F. to about 115.degree. F.
