In the 19th century century, the use of the tunnel type dryer marked the development of the dryer from intermittent operation to continuous operation direction. Rotary cylinder Dryer is better to realize the stirring of granular materials, drying capacity and strength can be improved. Some industries have developed to adapt to the industry requirements of the continuous operation of dryers, such as textile, paper industry drum dryer.

In the early 20th century, the dairy production began to apply spray dryer, providing a powerful tool for large-scale drying of liquid materials. In the 40 's, with the development of fluidization technology, the high strength and productivity of fluidized bed and air dryer appeared successively. The freezing sublimation, radiation and dielectric dryer provide new means to meet the special requirements. The 60 's began to develop far-infrared and microwave dryers.
