s1: during drying operation, a sample is placed on the top side of a transmission belt (8), the transmission roller is driven to rotate under the coordination of a driving motor (3), so that the rotation of the transmission belt (8) is realized, in the rotation process of the transmission belt (8), scrapers (5) on two sides of the top of the transmission belt (8) are matched with springs at two ends of a positioning shaft (6), the bottom side of each scraper (5) is connected with the surface of the transmission belt (8), when the sample rotates along the transmission belt (8), the sample rolls under the coordination of the scrapers (5) without departing from the transmission belt (8), and the positioning and drying of the sample are realized;
s2: in the drying process, gas is heated through an electric heating rod (10), the sample is dried under the cooperation of a fan (9), in the drying process, when the sample is placed on a transmission belt (8) and the whole quality in a drying box (1) is improved, the whole quality is weighed through a weight sensor (13), when the sample is dried, the upper part of a supporting plate (12) is increased in quality, the supporting plate (12) sinks, a second electrode plate (105) slides in contact with a first electrode plate (103), the power-on operation of an indicator lamp (15) can be realized, the prompt operation can be better, and the operation safety is ensured;
s3: in the drying process, water vapor in the sample is evaporated, the overall mass in the drying box (1) is reduced, the overall mass of the drying box (1) can be weighed in a matching way through the weight sensor (13), the water loss rate can be judged by comparing the overall mass with the mass before drying, the drying quality of the sample can be effectively mastered by controlling the drying time, and a proper sample reference can be provided for detection;
s4: in the stoving operation in-process, rotating electrical machines (23) operation, it is rotatory to drive the turbine shaft, at turbine blade (22) internal rotation in turbine shell (24), realize the pump drainage to the inside gaseous pump drainage of stoving case (1), in the pump drainage in-process, inside gas passes through blast pipe (205) and discharges, in the discharge process, because top port at blast pipe (205) is provided with shutoff cap (203), can realize the one-way exhaust of stoving case (1) inside gas, avoid the entering of outside gas, effectively improve stoving efficiency.
