Working principle

Drum drying equipment is an internally heated conductive rotary drying device. Wet materials transfer heat through thermal conduction on the outer wall of the drum to remove moisture and achieve the desired moisture content. The heat is transferred from the inner wall of the cylinder to the outer wall, and then passes through the material film. It has high thermal efficiency and can be operated continuously, so it is widely used for drying liquid or strip materials, and is more suitable for paste and viscous materials.

Structural form

It can be divided into two forms: single drum scraper drying equipment and double drum scraper drying equipment. Additionally, it can be divided into two forms based on operating pressure: atmospheric pressure drum scraper drying equipment and pressure reducing drum scraper drying equipment.

Product Features

1. High thermal efficiency, as the heat transfer mechanism of the drum drying equipment belongs to thermal conduction, the conduction direction remains consistent throughout the entire operation process. Except for cover heat dissipation and thermal radiation loss, the rest of the heat is used for the evaporation of moisture in the bucket film, and the thermal efficiency can reach 80% -90%.
2. It has high operational flexibility, wide practicality, and can adjust various drying factors of the drum drying equipment. Factors such as the concentration of the feed, the thickness of the coating film, the temperature of the heating medium, and the rotation speed of the drum can all change the drying rate of the drum drying equipment, and many factors are not interrelated. This brings great convenience to the drum drying operation, enabling it to adapt to the drying of various materials and meet the requirements of different yields.
3. The drying time is short, and the drying cycle of materials is often only 10-15 seconds, which is more suitable for heat sensitive materials. If the drying equipment is set in a vacuum chamber, it can operate under reduced pressure conditions.
4. The drying speed is high, and the film applied to the barrel wall is very thin, often between 0.3-1.5mm, with consistent heat and mass transfer directions. The surface of the film can maintain a weight of 30-70kg The evaporation rate of H2O/m2. h.
