Abstract

Described is a method of producing a non-aqueous DAF or DAF-like product and/or protein complex and/or free fat composition from a raw DAF or DAF-like stream. In one aspect, the method may comprise the steps of heating, separation, and drying of a raw DAF stream to form a non-aqueous DAF product. In an alternative aspect, the method comprises reducing the particle size of a raw DAF-like stream, storing; and drying to form a non-aqueous DAF product. A vacuum dryer is also described comprising a dryer body or dryer interior that moves during drying of a material therein to cause movement of the material being dried during a drying operation.
