New equipment for drying with full power to assist in the return of grain particles to the warehouse

The core of this technology is to make the grain rotate and rise with hot air during the grain drying process, avoiding mechanical impact and reducing the grain drying damage rate to less than 0.1%, achieving zero damage during the grain drying process. "On January 2nd, Xing Fuguo, the leader of the technology research and development and a researcher at the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences, said in an interview with Science and Technology Daily.

Reduce energy consumption by over 40%

At present, although China has made great progress in grain drying technology, the core technology with independent intellectual property rights is still very scarce. Therefore, we are determined to overcome the core technology of grain drying. Xing Fuguo said that traditional drying technology and equipment have three major bottlenecks, namely high grain damage rate, low drying rate, and low quality of grain after drying.

The biggest challenge facing Xing Fuguo is how to break away from traditional dryer technology and mechanical structure, and create new mechanical principles and structures. Except for the motor, all other equipment, systems, core components, and parts of the dryer need to be independently researched, designed, molded, tested, experimented, and manufactured, "said Xing Fuguo.

After countless technical routes and design principles were rejected, the "tornado" inspired Xing Fuguo and Liang Kai, the general manager of Hebei Haokai Agricultural Machinery Co., Ltd. Isn't the debris carried by a tornado equivalent to food? "The two of them began a simulation experiment to verify the feasibility of using air suction suspension to enhance food.

Improving drying efficiency is another challenge that the team needs to overcome. The key to improving drying efficiency is to use hot air throughout the entire drying process. Our developed dryer uses air suction technology, which increases the contact range between hot air and grain by twice compared to the technology used in traditional dryers, thereby improving the efficiency of hot air use. Xing Fuguo said that traditional technology uses one-time drying, while air suction technology uses secondary drying. The grain lifting process is divided into two processes: primary drying during the lifting process and secondary drying after entering the warehouse.
