An apparatus for puffing granular material, in particular cereals and legumes, has a heating apparatus for preheating the granular material and a puffing reactor for puffing the material. For effective, fast, and uniform heating of the material, it is proposed that: the heating apparatus have a free jet fluidized bed without a flow impact floor in which a batch of the material to be heated can be acted upon, in a preheating operation synchronized with the puffing process and proceeding batchwise, by a heat-carrying gaseous medium. |
