Abstract

A device for puffing foodstuff comprises an upright puffing reactor having a vessel for receiving foodstuff therein. The vessel has a wall provided with a plurality of openings. A chamber surrounds the vessel. The vessel has no openings in an upper section. A first pressurized heat-carrying agent is supplied to the chamber under a first pressure, and the agent flows from the chamber through the plurality of openings uniformly through the foodstuff disposed within the vessel. Shortly before the vessel is opened via an opening mechanism, a second agent having a higher pressure than the first pressure is supplied into the upper section above the foodstuff disposed within the vessel for providing a 'propelling charge' behind the foodstuff.
