ABSTRACT: Drying uniformity is one of the important indexes affecting the drying quality of products. The Drying Uniformity of carrot slices under different conditions was studied by dispersing microwave and moving materials in microwave chamber. Single factor experiments were carried out to study the effects of microwave agitator fan speed, material rotating speed, microwave drying equipment and carrot quality on drying uniformity.
The results show that the drying uniformity can be reduced by increasing the rotational speed of the microwave stirring fan and the rotational speed of the material turntable; the drying uniformity will be aggravated by increasing the microwave power, and the final product quality will be affected; the drying uniformity will be affected by different material quality under the same shape. The results provide the basis of operating parameters for improving the uniformity of microwave drying of carrot slices.
