Abstract: In order to explore a better method for grain concentrated drying, the researches of a set of concentrated drying methods with electric fans and energy-efficient heaters were conducted with references of in-storage drying and low-temperature drying. The results showed that it only took 0.143 yuan/kg for rice to be dried from 30% to 13% moisture content and 0.110 yuan/kg for wheat to be dried from 26% to 14% moisture content, the method is simple and practical with small space, and well resolved the issue of drying grains depending on the weather.
