摘要： A method of manufacturing a foamed foodstuff comprises the steps of inserting powdered and granular ingredients for a foodstuff into an extruder (1) of which a cylinder (5) is provided thereof with two screws (2) which mesh with each other and rotate at high speed in the same direction, mixing and heating the ingredients in a preheating zone (8), adding a predetermined quantity of a liquid to the mixed ingredients in a liquid-addition zone (9), kneading the moistened ingredients in a kneading zone (10), transforming the starch in the ingredients into alpha starch in an alpha formation zone (11), and then extruding the ingredients from the extruder. The method, therefore, requires no separate operation of adding the liquid to the ingredients and kneading them before they are loaded into the extruder. The kneading operation and the alpha starch formation operation are both conducted automatically and continuously within the extruder, so that a uniform product can be produced efficiently. The method is particularly effective for confectionery and the like.
