Detailed Description

In the embodiment shown in fig. 1 to 8, dry fruits are generally fed into the drying drum through a feed opening (1), and the feed opening is in U-shaped contact with a feed opening baffle (12) to facilitate feeding of the dry fruits into the drying drum; as shown in figure 1, the power required by the roller supporting shaft is provided by a power system (2), and the rotating speed of the roller is matched with the dried fruit drying time; as shown in fig. 2, the roller is fixed with the main shaft by the supporting plate, the main shaft is fixed on the frame by the bearing seat, and the bearing seat is connected with the frame by the bolt; the roller is of a porous structure, so that steam can be conveniently sent into the roller; as shown in fig. 3, the support plate is connected with the main shaft in an interference fit manner, the main shaft rotates to drive the support plate to rotate, so that the roller is driven to rotate, the support plate is connected with the roller through a bolt, the machine assembly is facilitated, and the support plate is fixed at two ends of the main shaft; as shown in fig. 4, the hot air bin (9) is of a U-shaped structure, so that the contact area of the roller is greatly increased, the roller is heated more fully and uniformly, the fan (3) sends cold air into the hot air bin (9), the electric heating wire (10) heats the air to change the air into steam, and the hot air bin (9) sends the steam into the roller through the heat dissipation holes (11), so that the aim of drying dry fruits is fulfilled; as shown in figure 8, the diameter of the upper semicircle and the lower semicircle of the discharge port baffle (13) are different, the diameter of the lower semicircle is smaller than that of the upper semicircle, and the diameter difference is determined according to the size of dried fruits, so that the dried fruits can be conveniently and smoothly discharged out of the discharge port.

When dry fruits are dried, the driving belt pulley is connected with the main shaft through a fastening screw, the main shaft is connected with a supporting plate fixed on the porous roller through a flat key, the main shaft is in interference fit with a bearing seat, the main shaft and the bearing seat are fixedly connected at two ends of the frame through bolts, the porous roller completes autorotation motion in the working period,
