Final answer: The Rotary Dryer, which consists of a rotating cylinder that materials flow through while encountering hot gas, is commonly used in industry due to its efficiency and versatility.

Explanation: The most common type of dryer, made up of a rotating cylinder, through which materials flow while getting in contact with hot gas, is identified as Rotary Dryer. Especially prevalent in industrial processes and engineering studies due to its efficiency and versatility. Material is added into one end of the rotating cylinder, often slightly inclined, and as it rotates, the material moves through the cylinder coming into contact with the hot gas which dries the material. Compared to the listed options of Tower dryer, Centrifugal dryer, and Trey dryer, the Rotary dryer is distinct in its ability to utilize direct or indirect methods of heating, ensuring thorough drying.
