Description

Technical Field

[0001] The utility model relates to the technical field of grain drying and processing, in particular to a two-way ventilation and drying device for grain. Background Art

[0002] Ventilation and drying treatment is of great significance for ensuring grain quality and extending storage period. It is an indispensable part of modern grain storage management. Grain ventilation and drying equipment is generally required in this process. It uses air as a medium and carrier, and under the action of natural wind pressure or fan pressure, allows air to pass through the grain pile to exchange heat and moisture with the grain, taking away the moisture from the grain, thereby achieving the purpose of drying. However, there are still some defects in the actual operation of grain ventilation and drying equipment.

[0003] Grain ventilation and drying equipment often requires users to constantly open and close the drying furnace to realize the loading and unloading operations of grain products, which is rather cumbersome. In addition, it only uses a single hot air blower for one-way blowing and drying. It is not easy to achieve efficient ventilation and drying processing through a two-way ventilation and drying structure, a drying temperature control structure, and a water removal structure. Based on this, we propose a new type of grain two-way ventilation and drying equipment to provide better use effects. Utility Model Content
