AI Technical Summary

Problems solved by technology

At present, the centrifugal drying equipment used on a large scale in China is limited by the hot air transportation problem, the temperature is unstable, and the hot air is easy to lose, resulting in high energy consumption, low thermal efficiency, and environmental pollution.

Therefore, the disadvantages of high energy consumption, low thermal efficiency, and high maintenance costs limit the use of these devices.

At present, the centrifugal drying equipment used on a large scale in China is subject to unreasonable structure and technology, and the detail design is not perfect. As a result, the internal materials of the drying equipment are easy to accumulate, resulting in the surface being dried and excessive moisture inside, which affects the overall drying effect.

At the same time, the material breakage rate is high, (especially the pills) are poorly formed, and it is not easy to clean and clean the machine.

Therefore, the disadvantages of high material damage rate, poor drying effect, and difficult cleaning limit the use of these equipment

Therefore, it is extremely important to solve the problems of thermal efficiency, temperature control, high material damage rate, poor drying effect and difficult cleaning and maintenance in the drying process of materials.
