The invention belongs to the technical field of medicine equipment and particularly provides an electrically heated drying oven with a temperature monitoring function. The electrically heated drying oven comprises an oven body, wherein a drying room and heat-insulating detection rooms are formed in the oven body; the heat-insulating detection rooms are located on two sides of the drying room; feed chutes are arranged at the top of the drying room; a feed table is arranged at the bottom of the drying room; a spiral feeding belt is vertically mounted in each heat-insulating detection room; the feed table is connected with the bottom of the spiral feeding belts; the tops of the spiral feeding belts are connected with the feed chutes; infrared heating tubes are mounted on the side wall of the drying room; temperature sensors are arranged at the connecting parts of the feed table and the spiral feeding belts; a humidity sensor is arranged in each heat-insulating detection room; the humidity sensors and the temperature sensors are connected with single-chip microcomputers; the single-chip microcomputers are connected with motor switches used for driving the spiral feeding belts. The electrically heated drying oven has the following benefits: drying and detecting of herbs are carried out independently to facilitate drying of the herbs, meanwhile, the temperature and the humidity of the herbs can be detected more precisely to facilitate circulatory drying of the herbs, and quality reduction of the herbs, caused by over-drying of the herbs, can be avoided.
