Description

Technical Field

[0001] The utility model belongs to the technical field of grain processing, and particularly relates to an energy-saving grain dryer with high-efficiency drying effect. Background Art

[0002] Grain dryer is a kind of equipment used to dry grain. It is usually composed of multiple drying bins, ventilation ducts, heat recovery chambers, burners, heat exchangers and other parts. It has the advantages of high efficiency, energy saving and environmental protection. It can greatly shorten the drying time, improve production efficiency, reduce energy consumption and reduce environmental pollution. It is widely used in grain processing and storage.

[0003] For example, a Chinese patent with publication number CN219347212U discloses a grain dryer with efficient drying effect, including a drying box, a lifting mechanism is fixedly arranged on the left side wall of the drying box, and a return mechanism connected to the lower part of the lifting mechanism is fixedly arranged below the left side wall of the drying box, and a feeding mechanism connected to the upper part of the lifting mechanism is fixedly arranged on the top of the drying box. By setting a cloth component, the size of the discharge port of two adjacent guide plates can be controlled by changing the inclination angle of the baffle, so as to control the speed and flow rate of grain falling, so that the grain and hot air are fully in contact, and the problem of poor drying effect caused by the incomplete contact of the hot air with the grain in the center position due to concentrated falling of grain is avoided. When the discharge port between the two guide plates is blocked by grain accumulation, the purpose of unblocking the discharge port is achieved by reciprocating swing of the baffle, so that the cloth component is always in a smooth and normal working state.

[0004] Although the grain dryer in the above patent can control the speed and flow rate of grain falling, in actual use, when grain enters the grain dryer, due to the high moisture content in the grain, it is easy for the grain to block the feed port, causing the grain to gather at the feed port, making it difficult for the grain to enter the dryer for drying.
