Abstract: A method is provided for producing a powdery product from a protein-containing liquid having a dry solid content, providing (1) a first feeding stream of protein-containing liquid, (2) a second feeding stream having a higher content of dry solids than the first feeding stream, (3) mixing the first feeding stream and second feeding stream to obtain a main stream, (4) heating the main stream in a heater, (5) transferring the heated main stream to a separator, (6) flash separating volatile components from the heated main stream and obtaining a main stream protein-containing concentrate, and subjecting at least a part of the main stream protein-containing concentrate to a drying step to obtain a powdery product. The amount of water to be evaporated in the drying step is significantly reduced, requiring smaller drying equipment, less air and less energy, and yields a powdery product having higher “bulk density”.

Abstract: A method for concentration of a liquid food product, the liquid product having a dry solid content of a least 40 percent and the liquid food product comprising crystallizable components, comprising the steps of heating the liquid food product to a temperature above the crystallization temperature of the liquid food product in a first heat exchanger; transferring the heated liquid food product to a first separator; flash separating volatile components from the heated liquid food product; and obtaining a liquid concentrate of the liquid food product.
