Patent ID: 7883886

Claim:
A device for malting grains comprising: a tower with a plurality of stories delineated by story floors; air-permeable annular supporting floors associated with each story being structured and arranged to support grain to be germinated; a central cylindrical space at an inner diameter of the annular supporting floors in which perpendicular channels extending over an entire height of the stories are arranged, the cylindrical space being divided to define the channels as segmented cross-sections that are separated from each other by radial intermediate walls; air flow paths associated with the plurality of stories comprising supply channels, displacement elements, and discharge channels, wherein an air flow path for a respective story comprises air flow through a respective supply channel, through respective displacement elements and a respective supporting floor and its associated grain, and through a respective discharge channel, whereas each of the perpendicular channels is allocated to a respective supply channel or a respective discharge channel, and both the supply channels and discharge channels extend within the central cylindrical space; and each story comprises: an outflow opening allowing an air flow path from a respective supply channel to a respective floor and its associated grain; and a flow-through opening allowing an air flow path to a respective discharge channel.
