ABSTRACT:
A continuous process for preparing a paste or cream like material which comprises the steps of means for forming under non vacuum conditions at a temperature of 90.degree. F. to 120.degree. F. a first low viscosity homogenous slurry of at least one non aqueous solvent and a gelling or bodying agent; means for forming a second low viscosity homogenous slurry under non vacuum conditions at a temperature of 90.degree. F. to 130.degree. F., means for forming a low viscosity mixture of said first low viscosity slurry and said second low viscosity slurry by a high shear mixing under non vacuum conditions at a temperature of 90.degree. F. to 130.degree. F. for 0.1 to 5 seconds; means for transforming under non vacuum and non mixing conditions at a temperature of 65.degree. F. to 120.degree. F., said low viscosity mixture into a non Newtonian mixture; and means for deaerating said non Newtonian mixture under vacuum conditions for a period of less than 3 seconds to form said paste or cream like material.
