At present, the main technology of grain dryer is embodied in low environmental protection, which is adapted to China's economic development. Environmental protection mainly refers to the small dust emission during grain drying, low carbon and sulfur pollution and low noise. Grain dryer power consumption and fuel consumption are smaller,customer costs are lower. Grain sawmill fully launched the concept of the earliest, and research and development and applied to practice, has indeed achieved the low consumption of environmental protection, the rapid popularity of foreign markets formally illustrates the correctness of the technical direction.

Dingli three-layer rotary drum dryer is a breakthrough in the heat utilization rate increased by 75%, significantly reducing the energy consumption of traditional drying technology, and the use of energy-saving environmentally friendly stove, not only reduce the dust content, while carbon and sulfur pollution also played a very good inhibitory effect.
