The appearing of grain dryer solves a lot of economic losses due to moisture, specially for crops. As we all know, the economic crisis is relative for the food crisis is simply insignificant. So in the field of grain dryer, countries and companies are constantly exploring new technology reform, to save food crops and contribute to society.

Our country and other in the world, are doing research on the new grain dryer, in order to provide food storage time reduce economic losses, and continued the next season the arrival of food.

We know that the entire dryer has a good ability to move jobs. It can be cross-operation and reduce operating costs, which is characteristic of the mobile grain dryer. The dryer is generally the drying chamber and control room in two parts composition. Here in the dry interior spiral stirrer, the food can flipped from top to bottom in the drying chamber 180 °. Since the initial grain moisture drying time and drying temperature is decided, in order to obtain a safe drying temperature, take multiple sampling test calculations to determine the temperature change time.
