Method for decontaminating bulk food and/or feed material, in particular raw food and/or feed materials, comprising the following method steps: - inserting the bulk material into a rotary tube dryer, - increasing the temperature of the bulk material by means of at least one infrared radiator up to a defined treatment temperature range while at the same time rotating the bulk material, - maintaining the temperature of the bulk material in the treatment temperature range during a treatment phase by means of the infrared radiator while at the same time rotating the bulk material, - reducing the temperature of the bulk material to a discharge temperature while at the same time rotating the bulk material, - discharging the bulk material from the rotary tube dryer. |
