Description

Technical Field

[0001] The invention relates to the technical field of sorghum processing, in particular to a sorghum slow-fall type hot air drying device. Background Art

[0002] Sorghum is an annual herb of the genus Sorghum in the Poaceae family, also known as millet, reed sorghum, and black grass. Sorghum stalks are thick and upright. The leaves are linear to linear-lanceolate, dark green on the surface, light green or powdery on the back. The panicle is loose, the main axis is exposed, and the peduncle is erect or slightly curved. The caryopsis is flat and convex on both sides, light pink to reddish brown, 2.5-3 mm wide when ripe, and the top is slightly exposed. The flowering and fruiting period is from June to September. Sorghum is rich in nutrients and is one of China's traditional staple foods. It can be eaten, fed, and used for brewing in daily life. It is a crop with high comprehensive utilization value. At the same time, sorghum has the characteristics of high yield and strong stress resistance, and has high research value on drought resistance. The sorghum caryopsis is flat and convex on both sides, 3.5-4 mm long, light pink to reddish brown, 2.5-3 mm wide when ripe, and the top is slightly exposed.

[0003] In my country, the sorghum planting area is large, and the season of mature harvest is prone to plum rain weather, and the seeds are prone to mold. Many places use sorghum drying devices to dry sorghum. For example, Chinese patent announcement No. CN114322491A discloses "a sorghum drying device", which uses an air energy heater, a dehumidifier, an exhaust fan, an outer cylinder and an inner cylinder to form a circulating dehumidification system to dry the red tassel sorghum in the inner cylinder. Spiral blades are arranged on the inner wall of the inner cylinder, and red tassel sorghum is injected into the inner cylinder from a feed hopper. During the rotation of the inner cylinder, the spiral blades can push the red tassel sorghum forward and evenly turn the red tassel sorghum, so that the hot air is in uniform contact with the red tassel sorghum, thereby avoiding the problem of uneven dehydration of the red tassel sorghum and improving the drying efficiency; However, in actual use, as the inner drum rotates, impurities attached to the surface of the sorghum fall off and mix with the sorghum, affecting the appearance of the processed sorghum. At the same time, the sorghum rotates in the inner drum, and the collision intensity is high, which can easily cause the undried sorghum to break and be damaged. Summary of the invention

At the same time, the sorghum is prevented from being damaged and broken due to violent collisions with each other due to stirring and the like, thereby improving the quality of the product sorghum. By arranging a filter net 5 to filter impurities in the sorghum, and discharging the impurities along the waste discharge mechanism 8, the impurities are prevented from mixing with the finished sorghum product and affecting the quality.
