Abstract
The utility model relates to microwave drying equipment, in particular to a tunnel-type microwave drying furnace. The tunnel-type microwave drying furnace comprises a furnace body and a conveying system, wherein a microwave furnace chamber is formed inside the furnace body; and the conveying system comprises a driving roller, a driven roller and a rotary conveying belt penetrating through the microwave furnace chamber. The tunnel-type microwave drying furnace is characterized in that a rib strip is arranged at the edge on each of the two sides of the conveying belt; a trough-type feeding channel is formed between the rib strips; the rib strips are made of a polytetrafluoroethylene material and are 0.5-3cm high; and a scraper device for spreading materials is further arranged at the feeding inlet of the furnace body. The tunnel-type microwave drying furnace has the benefits that materials are prevented from escaping from the edges of the conveying belt due to the rib strips, so that uniform material distribution is ensured and the sterilization and drying effects of the microwave are improved.

Adopt the beneficial effect of above-mentioned further scheme to be, the height of rib bar can be determined according to characteristic and the demand of institute's drying or sterilization material.
Further, the feeding mouth of described body of heater also is provided be used to the scraper that shakeouts material.
Adopt the beneficial effect of above-mentioned further scheme to be, because the setting of rib bar is conducive to adopt scraper to divide material, can utilize scraper that material is distributed very evenly.
Further, described scraper comprises support, rotating shaft, scraper plate and balancing weight, and described support is fixed on the both sides of described body of heater, and described rotating shaft is rotatably connected on described support, described scraper plate is fixed on the below of described rotating shaft, and described balancing weight is located at the top of described rotating shaft.
Adopt the beneficial effect of above-mentioned further scheme to be, this scraping mechanism is simple and practical, and scraper plate has the effect that material is advanced and shakeouts to the rib bar.Scraper plate has certain elasticity, and when individual cases had block material to occur, scraper plate can also suitably be raised automatically, the operation of not impact equipment.
Further, in described microwave cavity, also be provided with the isolation baffle plate, described isolation baffle plate is fixed in the described body of heater and the inner chamber of described body of heater is divided into sterilizing chamber and two sections of hothouse, and described isolation baffle plate upper and lower part is provided with sheet or pectiniform septum from air curtain corresponding to position, described grooved material road.
Adopt the beneficial effect of above-mentioned further scheme to be, material is different to early stage with the later stage working condition requirement generally in dry run, adopt the isolation baffle plate can form two microwave cavities of different atmosphere, control respectively temperature and humidity etc. with convenient, to obtain optimum efficiency; Sheet or pectiniform septum can alleviate two section atmosphere from air curtain crosstalks, and is more conducive to control.
