Along with the reform of rural areas and the transfer of land, the agricultural production organization model is undergoing profound changes. It is particularly manifested in the rapid rise of new agricultural management entities such as large-scale farms, family farms, agricultural cooperatives, large farm machinery, and large agricultural planters (specialized households). With the agricultural planting and management model, the problem of food concentration and rapid drying is more urgent than ever before, which has also led to the rapid expansion of the drying equipment market.
On March 25, 2015, Premier Li Keqiang presided over the executive meeting of the State Council, deployed and accelerated the implementation of "Made in China 2025" to realize the upgrading of manufacturing machinery for agricultural machinery and equipment. Miao Wei, Minister of the Ministry of Industry and Information Technology, said that we are not yet a manufacturing powerhouse for agricultural machinery and equipment, there is no large number of key enterprises with international competitiveness, and major technologies and agricultural machinery and equipment for industrial development urgently need to be broken through. Completing the transformation from a manufacturing powerhouse prepared for agricultural machinery to a powerhouse, smart manufacturing will be the main thrust.
The agricultural machinery and equipment that are one of the ten major areas for the “Made in China 2025” development need to promote the integrated development of producer services and manufacturing, and increase the manufacturing level and core competitiveness of agricultural machinery and equipment.
In the early 50's, China imported food series dryers and drying towers (rooms) from the former Soviet Union, and carried out the domestic design and manufacturing of drying towers. Although there are many forms, the basic structure is basically the same. The drying towers are all dried with high-temperature strong winds, and the drying process is carried out by drying the corn with hot air of downstream, countercurrent and mixed flow. The existence of a large volume of drying equipment, heat exchanger outside the tower heat exchanger, thermal energy loss, hot air is a one-time use rate, low utilization of thermal energy, hot air power consumption, waste heat can not be used and other issues. After drying, the quality of the corn is poor, and the drying time is long. The drying temperature is not easy to control. After the drying, the corn is broken and cracked seriously, resulting in increased losses in the circulation.
The drying of corn needs to maintain its original color, aroma, taste, shape and nutrient composition. It is necessary to eliminate problems such as solute loss, surface hardening, and quality degradation in the traditional drying process of corn; the cis-reverse circulating-flow low temperature corn drying tower can achieve The three goals of quality, energy saving and environmental protection provide a brand-new solution for low-cost, high-quality drying of corn and have a strong market competitiveness.

Drying Machine

Industrial dryers work through evaporation, or the process by which a liquid is converted into a gas and diffused into the atmosphere. Sometimes, dryers also engage in sublimation, which is when a solid changes directly into a gas.

All of these dryers perform drying action using one of three methods air drying, spray drying, and infrared drying. Of these, air drying is the most common. It works simply, by bringing materials being dried into direct contact with cold or hot air. Examples of cold and hot air dryers include fluidized bed dryers, rotary dryers, flash dryers, and freezed dryes.
