The material to be dried (17) passes through the connecting pipe (22) and reaches the supply hopper (18). When the material to be dried (17) reaches the supply hopper (18), it falls into the hopper due to its own weight and accumulates therein. However, only the air drawn by the blower (26) flows toward the blower (26) through the filter (19) and the ventilation pipe (29). In this way the supply hopper (
When a predetermined amount of the material to be dried (17) has accumulated in the chamber (18), the blower (26) is stopped and the valve (20) is opened to remove the material to be dried (18).
17) is allowed to fall into the drum (7) via the supply pipe (15) and opening (8). Then the motor (I
2) to rotate the drum (7) and the magnetron (5) to supply microwaves to the heating section (1) and into the drum (7) through the opening (8). Thereby, the material to be dried (17) is efficiently dried using microwaves while being sufficiently stirred by the drum (7). Needless to say, at this time, the take-out pipe (16) remains fixed without rotating together with the drum (7). When drying is completed, stop the magnetron (5) and motor (12), close valve +20) (27), and close valve (28).
) and operate the intake blower (26) again. Then, due to the suction action of the blower (26), the drum (
7), the dried material (17) is taken out from the pipe (
16) and reaches the take-out hopper (23). When the dried eJ (171) reaches the take-out hopper (23), it similarly falls and accumulates in the hopper due to its own weight.
The air generated by the intake air in step 6) flows toward the blower (26) through the filter (24) and the ventilation pipe (30). When the material to be dried 07) has accumulated in the take-out hopper (23) in this manner, the blower (26) is stopped and the valve (25) is opened to allow the material to be dried (17) to proceed to the next process.
