Abstract: Bean paste having a good plasticity is advantageously made to granules through the transformation to strips, without any fear of coagulation thereof into a mass, on account of the bean paste being made to strips by an extrusion under such vacuum which excites immediate dryness and cooling of stripped bean paste.
Abstract: Hydrated materials such as bean paste are controlled as to their moisture content to an intermediate moisture content such as 12% to 40% on dry basis and higher than their plastic limit, and are then extruded into strips under vacuum, followed by the granulation of said strips under vacuum by applying thereto mechanical shearing force to produce granules of desired sizes.
