Abstract
The utility model relates to a single-stage belt type no-leakage microwave drying machine which comprises a case, a material conveying belt device, a feeding device, a discharging device and a plurality of microwave generators. The material conveying belt device comprises a driving roller, a driven roller and a conveying belt. The microwave generators are arranged above the conveying belt at intervals. The driving roller is arranged outside the case, and the driven roller is arranged in the case. The portion, where the conveying belt penetrates through, of the side wall of the case is provided with a choke groove of a rectangular cylinder. One side wall of the cylinder is provided with an elongated slot. The length of the elongated slot is larger than the width of the conveying belt. The choke groove is fixedly connected with the case through the side wall adjacent to the elongated slot which is formed above the conveying belt downwards. The microwave drying machine is simple in structure; by means of the reflecting effect of the choke groove, microwaves which radiate to an outlet and inlet portion and are possibly leaked are reflected to materials or reflected into a drying bin, namely, a microwave action area is completely shielded into the drying machine, and the drying efficiency is high.
