Product Description

Our potato starch drying drum is a continuous rotating drying equipment with internal heat conduction. The rotating drum adheres to a certain thickness of potato starch material through its lower trough, and heat is transferred to the inner wall of the drum via pipes, then conducted to the outer wall of the drum, and finally to the material, causing the moisture in the material to evaporate and dehumidify, thereby drying the moisture-containing material. The dried material is scraped off from the drum by scraper blades installed on the drum surface and sent to a spiral conveyor located below the scraper, where the dried material is concentrated and packaged through the conveyor.

Product Features

High thermal efficiency.

The heat transfer mechanism of the potato starch drying cylinder is conductive, ensuring a consistent heat transfer direction throughout the operation cycle. Besides heat dissipation through the lid and losses, the remaining heat is utilized for evaporating moisture in the drum material, achieving a high thermal efficiency of 70%-80%.

2. Flexible operation, wide applicability.

Many drying coefficients of the potato starch drying drum can be adjusted. Factors such as the concentration of the feedstock, the thickness of the coating film, the temperature of the heating medium, and the speed of the roller can all alter the drying efficiency of the potato starch drying drum. Many of these factors are unrelated to each other. This greatly facilitates the operation of the potato starch drying drum, allowing it to accommodate the drying of various materials and meet different production requirements.

3. Short drying time.

The drying cycle for materials typically ranges from 10-300 seconds, suitable for heat-sensitive materials.

4. High drying rate.

The material film applied to the cylinder wall is thin, typically ranging from 0.3 to 1.5mm, and the heat and mass transfer directions are consistent, allowing the film surface to maintain an evaporation rate of 20-70kg.
