Description

Technical Field

[0001] The utility model relates to the technical field of grain drying equipment, in particular to a drum type drying equipment used for grain processing. Background Art

[0002] Grain drying equipment is a mechanical device used to dry harvested grains (such as corn, wheat, rice, etc.). After the grain is harvested, due to adverse weather or environmental conditions, the moisture content of the grain may be too high. If the moisture content is not reduced in time, it is easy to cause problems such as grain mildew and germination, thereby affecting the quality and shelf life of the grain. In most existing grain drying processes, the common practice is to use the static drying method, which mainly spreads the grain flat in a drying room or drying area, and relies on natural wind or heated air to dry the grain.

[0003] Although this method is simple to operate and has low cost, it has some significant disadvantages. First, the drying uniformity is poor because the different layers of grain have different areas of contact with air and different degrees of heat absorption, resulting in different degrees of dryness between the bottom and upper layers of grain. This not only affects the drying effect, but may also lead to a decline in grain quality. Secondly, the efficiency of drying in a static manner is low because of insufficient heat and air circulation. In addition, the grain stacking density is large, and the evaporation of water and the heat transfer process are slow, which greatly prolongs the drying time.

[0004] Based on this, we propose a drum drying equipment for grain processing to solve the above-mentioned problems. Utility Model Content
