[0024] The inside of the bottom cavity 12 is scraped by a silicone scraper 111 disposed on the side of the stirring plate 110 close to the inner wall of the mixing box 11, so that the powdered raw materials on the surface adhere to the inner wall of the bottom cavity 12, thereby improving the mixing effect of the raw materials.

[0025] As attached Figure 5 As shown, the paving device 3 includes a paving plate 31 , which is fixedly mounted on the top of the mixing box 11 , and a gap is left between the bottom of the paving plate 31 and the surface of the ceramic heating plate 15 .

[0026] Through the gap between the bottom of the laying plate 31 and the surface of the ceramic heating plate 15, when the raw materials pass through the feed hopper 16 and enter the surface of the ceramic heating plate 15, the raw materials will slide on the surface of the ceramic heating plate 15 due to the influence of gravity, and will be intercepted by the paving device 3, and the raw materials will be spread flat on the surface of the ceramic heating plate 15, so that the raw materials are heated evenly and dried quickly.
