The application provides a peanut
drying machine and
drying method based on
microwave and hot air cooperation, wherein the
drying machine comprises a drying main cabin, a multifunctional treatment cabin is connected to one side of the drying main cabin, and a driving device drives a material bucket to revolve around a hot air duct and revolve around a central axis of the material bucket. The material bucket is exchanged between the drying main cabin and the multifunctional treatment cabin through a transfer track, a plurality of
microwave devices are arranged in the circumference of the shell of the drying main cabin, the
microwave devices are used for emitting microwaves to dry the peanuts in the material bucket, and the outer part of the multifunctional treatment cabin is respectively connected with a feeding device and a discharging device. The application seamlessly integrates three key processes of preheating, drying and
tempering in one equipment, realizes automatic switching through physical rotation, forms a complete closed-loop
processing chain, greatly simplifies the
production line and reduces the material turnover loss. Through the uniform temperature in the preheating stage and the slow
recovery in the
tempering stage, the color,
flavor and nutritional ingredients of the peanuts can be better maintained.
