    • In order to pest control food such as f.e. beans and dried mushrooms there is provided in a gas tight food storage room an inert O₂ lacking atmosphere with O₂ between O and 5%, CO₂ between 1 and 20% and the ba­lance N₂. This atmosphere is maintained until mor­tality of the pest. The system for providing this at­mosphere includes essentially a generator, which can be a combustion chamber (1) associated to a catalytic chamber (2) (in the case of an open circuit system in which air is drawn from the atmosphere) or a catalytic chamber alone (in the case of a closed circuit system in which air is drawn from the food storage room itself) and a cooling tower (3).
      The system is generally provided also with an evapora­tor (5) and a condenser (6) to control the humidity of the inert atmosphere, and a heat exchanger (7) in which the combustion heat is utilized to heat the inert atmosphere at a temperature which speeds up the mortality of the pest.
    • 为了防治食物如f.e. 豆类和干蘑菇提供在气密性食品储藏室,惰性O2缺乏气氛,其中O 2为O和5%之间,CO 2为1%至20%,余量为N2。 维持这种气氛直到病虫害死亡。 用于提供该气氛的系统基本上包括发生器,其可以是与催化室(2)相关联的燃烧室(1)(在空气从大气中抽出的开路系统的情况下)或催化室 (在从食品储藏室本身吸入空气的闭路系统的情况下)和冷却塔(3)。 该系统通常还设置有用于控制惰性气氛的湿度的蒸发器(5)和冷凝器(6),以及热交换器(7),其中利用燃烧热来加热惰性气氛, 加速病虫害死亡率。
