Then, after the dendrobium strips are heated to generate water vapor, the rotation of the scraper unit accelerates the wet air to be discharged vertically upward from the upper feed pipe 8. After drying is completed, the drawer 19 is pulled out, and the dried dendrobium strips are discharged along the lower feed pipe 9 for collection, which solves the problem of low drying efficiency caused by the long discharge path of hot air with moisture in the existing dryer.

[0025] The hot air unit comprises an electric heating box 3; the electric heating box 3 is fixedly connected to the support frame 1; a hot air pipe 5 is symmetrically connected and fixedly connected to the electric heating box 3; the air inlet of the electric heating box 3 is connected and fixedly connected to a blower 4; the end of the hot air pipe 5 is connected and fixedly connected to an outer cylinder 6; a motor frame 21 is fixedly connected between the blower 4 and the electric heating box 3; when working, a large amount of heat is generated by energizing the electric heating box 3, and then when the blower 4 is powered on, the heat is continuously blown along the hot air pipe 5 along with the air. The fresh dendrobium strips enter the outer cylinder 6 to be heated, and pass through the gaps and through holes between the inner cylinder 15 and the outer cylinder 6 to heat the inside of the inner cylinder 15, so that the dendrobium strips in the inner cylinder 15 can be heated in all directions, and the dendrobium strips are stirred by the scraper unit so that the dendrobium strips are heated evenly, and then the hot air with moisture is discharged along the upper feed pipe 8, so that the drying efficiency is greatly increased, which solves the problem of low drying efficiency caused by the long discharge path of the hot air with moisture in the existing dryer.

[0026] The scraper unit includes a hard scraper 11; a plurality of the hard scrapers 11 are fixedly connected to the central axis 10 in a circumferentially symmetrical manner; ventilation holes 12 are evenly distributed on the hard scraper 11; a soft scraper 13 is detachably fixedly connected to the end of the hard scraper 11; the soft scraper 13 is in contact with the inner surface of the inner cylinder 15; when working, the hot air in the inner cylinder 15 is integrated through the ventilation holes 12, and is not separated into independent spaces by the hard scrapers 11, so that the heat is uniform and in contact with the outside air at the same time, and the rotation of the hard scraper 11 accelerates the discharge of hot air, so that the water vapor in the dendrobium can be quickly taken away by the rising hot air, thereby greatly increasing the drying efficiency and solving the problem of low drying efficiency caused by the long discharge path of the hot air with moisture in the existing dryer.
