In agricultural production, the drying process of grain is crucial to ensure the quality of grain and extend its storage period. With the acceleration of agricultural modernization, grain drying towers have become indispensable equipment in agricultural production. This article will introduce the function and working principle of the grain drying tower.

1. The function of grain drying tower

Improve grain quality: Through the grain drying tower, the moisture content of grain can be controlled within an appropriate range, thereby improving the quality and taste of grain.

Extend the storage period of grain: Humid grain is prone to mold and deterioration, and reducing the grain moisture to a safe level through a grain drying tower can extend the storage period of grain and avoid losses caused by mold and deterioration.

Improve agricultural economic benefits: The use of grain drying towers can effectively reduce grain losses caused by moisture and improve the economic benefits of agricultural production. At the same time, the dried grain is easy to transport and store, which helps expand the sales scope of agricultural products.

2. Working principle of grain drying tower,The working principle of the grain drying tower is mainly divided into the following steps:

Pretreatment: The grain to be dried is screened, cleaned and other pre-processed to ensure uniform quality of the grain entering the drying tower.

Heating: The burner burns fuel to generate heat energy, and transfers the heat to the dry medium (such as hot air) to heat it up.

Drying: Pass the heated drying medium into the drying tower to exchange heat with the grain to be dried to evaporate the moisture in the grain to achieve drying of the grain.

Exhaust: The drying medium containing water vapor is discharged from the drying tower and processed through dust collector and other equipment to comply with environmental protection requirements.

Circulation: Circulate the processed drying medium to the drying tower again for the next round of drying operations.

In short, grain drying towers play an important role in ensuring food security. With the advancement of agricultural modernization, it is believed that this equipment will play a greater role in agricultural production and agricultural development, and make greater contributions to ensuring food security, improving agricultural economic benefits, and promoting sustainable agricultural development.
