摘要：
The device for killing harmful organisms at surface and/or in edge layer of pourable plant products includes gas and water supplyable chamber (1) with gas flow for isolating and swirling the products and movable source that emits ultraviolet-, electron- /microwave energy in the chamber. The gas flow (3) is directed in such a way that its effect is partially against the force of gravity. The ultraviolet energy exhibits a wavelength of = 230 nm. The source is arranged within the chamber or is integrated in a chamber wall. The device for killing harmful organisms at surface and/or in edge layer of pourable plant products, includes gas and water supplyable chamber (1) with gas flow for isolating and swirling the products and movable source that emits ultraviolet-, electron- /microwave energy in the chamber. The gas flow (3) is directed in such a way that its effect is partially against the force of gravity. The ultraviolet energy exhibits a wavelength of = 230 nm. The source is arranged within the chamber or is integrated in a chamber wall. The gas is a protective gas, an inert gas, air or a reaction product of undesirable chemical reactions such as carbon dioxide. The gas is sterilizable or germ reducible by a mechanism before entering into the chamber, and is heatable by another mechanism. The chamber comprises a reflector (7) formed as electron target for reflecting the energies. The plant products are processed in continuous- and batch processes by members. The chamber inner walls and surfaces areas of the plant products are subjected with the energies, during the isolation and swirling of the products. The flow properties of the gas are adjustable within the chamber.
