The aim of this research is to study moisture reduction of maize kennels for animal feeding by simulatingcontinuously mixing flow hot air dryercondition using a bucket conveyer and applying infrared radiation (IR) for heating in order to enhance the efficiency of moisture reduction. In accordance with additional heating, the infrared radiation area was installed at the position between the dryer and the bucket conveyer. The initial moisture content (IMC) of the maize kennels was 20, 30 and 40% (wet basis). Subsequently, the infrared heating with wave length of 1-2 µm was used for 1, 2 and 3 mins. The dried maize kennels were then tempered for 15 min. Finally, hot air with temperature of 45 ºC was blown through the kennels for 15 mins. In order to simulate this process 6 cycles were tested. The results showed that the increase in heating time with the use of infrared radiation leads to the decrease in final moisture content (FMC) of the maize kennels for animal feeding. Furthermore, with different initial moisture content, it was found that the higher initial moisture content results in the longer drying time and maize drying cycle in order to provide the moisture reduction at a safe storage level.
