Continuously puffing finely-divided particulate food materials utilizing opposing steam forces
Abstract
Abstract HEAT AND PRESSURE REACTIVE PARTICULATE FOOD MATERIALS SUCH AS CEREAL FLOUR, COCOA POWDER, POTATO FLOUR, OR FINELYDIVIDED PROTEIN CONTAINING MATERIALS ARE TREATED IN AN APPARATUS WHEREIN THE FOOD MATERIAL IS PROPELLED THROUGH A TREATMENT ZONE CONTAINING STEAM AT A PRESSURE OF BETWEEN ABOUT 15 P.S.I.G. AND 110 P.S.I.G. BY A STEAM FLOW WHICH ITSELF IS AT A PRESSURE OF AT LEAST 15 P.S.I.G. AND A TEMPERATURE OF BETWEEN 250*F. AND 500*F. ONCE THE FOOD MATERIAL PASSES THROUGH THE TREATMENT ZONE IT IS THEN CARRIED INTO A ZONE OF LOWER PRESSURE. THE OPPOSING FORCES ON THE FOOD MATERIAL FROM THE FLOW OF STEAM AND THE STEAM PRESSURE IN THE TREATMENT ZONE RESULT IN THE MATERIAL BEING EITHER PUFFED, TEXTURIZED, GELATINIZED, HOMOGENIZED OR AGGLOMERATED.
