Drum dryers, also known as industrial dryers, are a type of drying equipment used for drying materials such as granules, powders, or pastes. This system consists of a …
In ordinary drum drying, the process is controlled by varying the moisture content of raw material (pre-concentration), the temperature of drum surfaces, the space between the drums, the speed of rotation of the drums, and the amount of vacuum applied. However, drum drying is seen as a classical method suited for low-value products.
Triple-pass dryer technology offers superior dehydration solutions by optimizing operating costs, efficiency, and product consistency. The engineers at Baker-Rullman have developed and refined rotary drying through the years, demonstrating that the triple-pass design is the most reliable and proven technology available.
