Description

Technical Field

[0001] The utility model relates to the technical field of grain drying equipment, in particular to a hot air stove. Background Art

[0002] The hot air furnace of corn drying equipment refers to the high-temperature flue gas obtained after the combustion reaction of the fuel is mixed with the air in the environment to a certain set temperature and then directly enters the drying room or baking room, contacts with the dried material, heats and evaporates the moisture, thereby obtaining a dry product.

[0003] For example, a grain drying equipment is recorded in the patent with patent application number CN202022367806.8, which records that a grain drying placement box, a sealing ring block, a bottom ventilation net and a ventilation and heat dissipation port are set. When in use, the grain to be dried is placed inside the grain drying placement box, and the mesh size of the bottom ventilation net and the ventilation and heat dissipation port set on both sides of the grain drying placement box is set to a size that does not allow grain to pass through, which is conducive to ventilation of the inside and bottom of the grain on both sides, so that hot air can better enter the inside during the drying process. The sealing ring block ensures the sealing of the connection between the grain drying placement box and the grain drying equipment. The overall structure is simple and complete, and it is easy to use and operate.

[0004] In the above case, the grain was not screened during the grain drying process, and impurities easily entered the drying box, resulting in a large amount of impurities in the grain after drying. Manual screening was required, and the device was not convenient for collecting the corn after drying.

[0005] Based on this, a hot air furnace for corn drying equipment is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
