Firstly, pouring the granular materials into a hopper 020, switching a second three-way valve 06 to a second air source conveying passage 0602, and opening an air blower to blow the granular materials into a charging barrel 02 through a material blowing pipe 03; after the charging is finished, the blowing direction of the second three-way valve 06 is changed, the airflow is guided to the first air source conveying channel 0601, the airflow blows the bottom particles to the top through the blowing pipe 03, the particles are sprayed to the top along with the airflow, and the particles fall to the bottom of the charging barrel 02 after colliding with the material scattering disk 021 and cover layer by layer, so that the material turning from the bottom to the top is finished; when the stirring, the microwave drying assembly at the top continuously works to dry the granules in the charging barrel 02 by emitting microwaves.

The feeding process comprises the following steps: when the handle 01205 is rotated to align the middle part of the rotating disk 01201 to the bottom pipe opening 0204 of the charging barrel 02, the sealing rubber ring 025 at the outer side of the pipe opening 0204 at the bottom of the charging barrel 02 is tightly attached to the bottom surface of the rotating disk 01201 to be sealed with the outside to prevent air leakage, the second three-way valve 06 communicated with the air outlet of the air blower is communicated with the second air source conveying channel 0602, pressure air is blown into the feeding pipe 0208 through the first three-way valve 0603, and the air flow brings the particles added into the hopper 020 into the charging barrel 02 together, so that the feeding operation process of conveying the particles from the hopper 020 to the charging barrel 02 is completed.

And (3) drying: when a pipe opening 0204 at the bottom of the charging barrel 02 is aligned with a first through hole of the rotating disc 01201, which is communicated with the air inlet U-shaped pipe 014, the wind power of the blower is blown into the charging barrel 02 from the air source conveying channel 1601 through the air inlet U-shaped pipe 014 and the bottom of the material pipe, the granular materials at the bottom are blown out through the material pipe in an upward overturning manner, and the bulk material disc 021 meeting the top of the pipe falls into the charging barrel 02; meanwhile, the microwave magnetron 07 works and blows in a reciprocating and circulating mode to finish the microwave drying process. The granule material moves downwards and turns upwards layer by layer in the working process. The microwave emits microwave to the granular material, and the granular material is dynamically and uniformly heated. And in the process that the bottom granular materials are turned upwards along with wind power, the granular materials are cooled again by the wind power, and the granular materials are dried after multiple cycles. The particles are heated and cooled uniformly in the drying process, and local overheating or heating failure can not occur.

The microwave drying and the wind-up granule material turning can be carried out simultaneously, or the working time of the air supply and the microwave magnetron 07 can be separately controlled according to a set program, and the program can properly adjust the frequent proportion of the work according to the initial temperature condition and the drying intensity requirement. When the temperature sensor 10 detects that the heating temperature is low, the working mode of the blower can be adjusted to be intermittent operation, and the microwave magnetron 07 is operated all the time. When the set temperature is reached, the microcomputer in the control electric box 011 automatically controls and reduces the working strength of the microwave magnetron 07 to prevent the particles from being overheated. And when the heating drying time reaches the time preset by the program, controlling the program to automatically stop heating and blowing to finish drying the cylinder of granular materials.

And (3) discharging: when the switching mechanism 012 is rotated to align the bottom nozzle 0204 of the charging barrel 02 with the second through hole 01203 communicated with the discharging pipe 013, the particles in the charging barrel 02 directly fall from the feeding hole 0301 under the action of gravity, and flow out through the discharging pipe 013 and fall, so that the discharging process is completed.
