The research of grain drying equipment abroad started in the 1940s. Mechanization of grain drying was basically realized in the 1950s and 1960s. Grain drying was automated in the 1960s and 1970s. Grain drying was efficient and quality in the 70s and 80s. Energy saving, cost reduction, and computer-controlled development have led to serialization and standardization of grain drying equipment after 90 years. In recent years, great progress has been made in computer simulation of grain drying processes. The continuous development of traditional software and special software has played an extremely important role in the design of grain drying machinery and the improvement of product quality.

The development of grain drying machinery in China began with the imitation of dryers from Japan, the former Soviet Union and other foreign countries. Due to the complex structure of the grain drying machinery at that time, the high consumption of steel, and the high cost of production, it was not suitable for the economic and institutional conditions in rural areas and was used only by state-owned farms, grain stores and collective enterprises. In the late 1970s, relevant scientific research units began to develop grain dryers suitable for China's national conditions. Most of them are suitable for use by farm production companies and rural production teams; after the 1980s, China's rural economic system began to undergo reforms, and most of the dry machines developed were developed in the direction of multi-use and miniaturization; since the 1990s. With the in-depth development of rural reforms, the level of rural economy and agricultural productivity has risen relatively quickly, and professionalization and intensive management of scale have also witnessed new development. In particular, large-scale grain warehouses and seed and grain production bases of state-owned agricultural land reclamation systems gradually equiped with complete sets of grain drying equipment, and supported them with warehousing, processing, and other facilities to become the main application representatives of grain drying machinery in China; at the same time, they were also introduced. The grain drying machinery in the United States, Canada, Japan, and Taiwan and other countries and regions, some colleges and universities and related scientific research units have also developed a corresponding series of grain drying equipment to serve the domestic food system. The development of grain drying technology gradually makes the drying machinery mature and perfect, and it also accelerates the pace of agricultural modernization.
Although the development of grain drying machinery in China has been a continuous exploration history for more than 30 years, there are already more than 50 production enterprises. However, the output is not large, the technical content is low, there are few mature models, there are few product types, and the energy consumption is high. The automation level is low, and there is a lack of small and medium-sized multi-functional drying machines suitable for agricultural machinery specialized households, large grain producers, and village groups. There are more than 20,000 grain drying machines in the country. Mechanically dried grains account for only about 1% of the country's total production each year. The mechanical grain drying in the developed countries accounts for about 95% of the total output. This shows that China's grain drying machinery has developed. Far from being able to adapt to the needs of grain production development.

The grain dryer is a dryer assembly. It is the collective name for various equipments for grain dryers. Can also be a grain dryer, such as corn dryers, rice dryers, rice dryers, wine slag dryers, etc., we can all call it a grain dryer.
