Large-batch grain drying production line

Abstract

The invention discloses a large-batch drying production line which comprises a circulation conveying line which can cyclically convey grain products. A grain preheating area, a grain warming area, a grain drying area and a grain cooling area are sequentially arranged on the circulation conveying line from a grain inlet end to a grain outlet end. The grain outlet end of the circulation conveying line is provided with a grain separation and filtering area. The grain preheating area, the grain warming area and the grain drying area are provided with grain heating spaces for grain to pass. The temperatures of the grain heating spaces are sequentially increased from left to right, the highest temperature of the grain heating spaces is lower than 60 degrees, and the temperatures of the grain heating spaces of the grain preheating area, the grain warming area and the grain drying area are independently controlled.

Description

technical field [0001] The invention relates to grain drying equipment, in particular to a large-volume grain drying production line. Background technique [0002] China is a country with a large population, and the safe storage of grain is related to the livelihood of the people. Before storage, grains such as corn and rice must be dehydrated and dried to reach a safe moisture content, so as to prevent mildew and deterioration during storage. In the past, grain drying was mainly done by natural drying, which took up a lot of space, took a long time, and caused a lot of losses, making it difficult to meet the needs of centralized grain storage and transportation. In order to solve this problem, in recent years, people have used grain drying towers to dehydrate grain. The disadvantage is that the heat loss during the drying process is large, energy is wasted, and environmental pollution is caused; The grain may be overheated and cause coking, but the grain in the center is n...

Problems solved by technology

In the past, grain drying mainly relied on natural drying, which took up a lot of space, took a long time, and caused a lot of losses. It was difficult to meet the needs of centralized grain storage and transportation.

In order to solve this problem, in recent years, people have used grain drying towers to dehydrate grain. The disadvantage is that the heat loss during the drying process is large, energy is wasted, and environmental pollution is caused; The grain may be overheated and cause coking, while the grain in the center is not dehydrated due to less heat, resulting in a decline in grain quality and poor drying effect
