Abstract (en)
[origin: EP0113900A1] In the device, the method and utilization thereof for the industrial treatment by microwaves of alimentary pastes in bulk (56), the alimentary pastes (56) are conveyed by a mechanical conveying unit (9; 30; 59; 100; 101) controlled by a passage drum (9; 30) through a treatment chamber (4; 60; 80; 102). It is essential that each portion of the bulk material (56) is exposed to conditioned air and that a relative motion is generated between the conditioned air and the isolated portion of bulk material (56). The treatment chamber (4; 60; 80; 102) may be supplied with microwave energy by an extended field radiation source (125) or by a direct decoupling (8) providing from a wave guide (7; 122; 123; 145). Thereby, a very good spatial and chronological distribution of microwave energy is obtained. It is possible for example to heat and/or dry successfully pastes (56) or other foot products, to remove the bitterness of soya-beans and to roast the beans according to the continuous passage system. It is further possible to puff snacks, tobacco stems, etc.
