The eight-layer disc dryer with an annual output of 2000 tons is ready for delivery when it is officially completed. The disc continuous dryer is an efficient conductive continuous drying equipment. Its unique structure and working principle determine its high thermal efficiency, low energy consumption, small floor area, simple configuration, convenient operation and control, and good operating environment. It is widely used in drying operations in chemical, pharmaceutical, pesticide, food, feed, agricultural and sideline products processing and other industries. It is highly praised in the use practice of various industries.
Technical characteristics
（一）Drying tray
1、Design pressure: generally 0.4MPA, even up to 1.6MPA
2、Heating medium: steam, hot water, heat transfer oil and drying pan are heated with hot water at 100 ℃, saturated steam or superheated steam of ≤ 0.4MPA at 100 ℃ - 150 ℃, heat transfer oil at 1500 ℃ - 320 ℃, and electricity, heat transfer oil, molten salt and other methods can be used when the temperature is ＞ 320 ℃.
（二）Material transfer system
1、Spindle speed: 1-10 rpm, electromagnetic or variable frequency stepless speed regulation
2、Rake arm: there are 2-8 rake arms fixed on the main shaft on each drying plate
3、Rake blade: it is hinged on the rake arm and can keep in contact with the disc surface floating up and down. There are many forms
4、Rolling: For materials without caking and needing to be broken, add rolling at proper position to strengthen heat transfer and drying process
（三）Monoblock
There are three forms: atmospheric pressure, airtight and vacuum
1、Normal pressure type: cylindrical or octagonal, with integral and split structures. The main pipes of heating medium inlet and outlet can be inside the shell or outside the shell.
2、Vacuum type: round and simple shell, the design pressure is 0.1MPA, and the main pipes of heating medium inlet and outlet are in the shell.
（四）Air heater
It is generally used when the evaporation capacity is large to enhance the drying efficiency.
