During this work, drying tests of carrot discs arranged in a thin layer on a fixed bed were carried out on a hot air dryer. This study was limited to the influence of the air temperature for the dehydration of these washers without any pretreatment. The experiments were performed for two temperatures: 50 and 70 ° C at an air speed of 1m/s while performing other experiments for air speeds and different forms of cutting in order to compare the results. It turned out that the drying air temperature controls most of the drying process of this food
