    • Almonds, other nuts, grains, dried or dehydrated fruits or vegetables, and other agricultural foodstuffs resting on a porous mesh conveyor belt (22, 54) pass continuously through a chamber (20, 60) in which they are contacted by a gaseous oxidizing agent at atmospheric pressure as the conveyor belt and food products move continuously through the chamber. In one embodiment, the chamber is disposed through a barrier (56) which isolates a raw product receiving region from downstream processing facilities to prevent cross-contamination downstream. In another embodiment, the chamber (20) is disposed through a barrier (34) which separates a husker (14) from a downstream Sheller (40) such that the shells are sanitized prior to releasing the nutmeats from the shells. In the preferred embodiment, the gaseous oxidizing agent is hydrogen peroxide at a 1.8 mg/liter concentration which flows up through the belt vibrating the food products without scarring them as the belt conveys the food products through the chamber for a duration of about 15 seconds to achieve a 3 log reduction in human pathogens.
    • 杏仁,其他坚果,谷物,干燥或脱水的水果或蔬菜以及搁置在多孔网状输送带(22,54)上的其他农业食品连续地通过其中与气态氧化剂接触的室(20,60) 在大气压力下,传送带和食品连续移动通过室。 在一个实施例中,室被布置成穿过屏障(56),该屏障将原始产品接收区域与下游处理设备隔离,以防止下游的交叉污染。 在另一个实施例中,室(20)设置穿过将脱壳器(14)与下游刮板(40)分离的屏障(34),使得壳体在将壳体从壳体释放之前被消毒。 在优选实施方案中,气态氧化剂是1.8mg / l浓度的过氧化氢,其通过带向上流动振动食品而不会使其疤痕,因为带将食品通过室传送约15秒的持续时间, 实现人类病原体减少3 log。
