Baker-Rullman rotary drum dryers use less fuel per ton of product than many other drum dryers and do so in significantly less space. The triple-pass design provides approximately three feet of horizontal material travel for every foot of drum length. Precise electronic controls eliminate heat surges and fuel waste. High BTU efficiency

Rotary dryers are the workhorses of the drying industry because of their capacity, efficiency, and ability to adapt to new purposes. Rotary drum dryers can be chosen for projects large and small. They come in all sizes to accommodate many products, quantities, and moisture content ranges. Although they can be much larger, a 14’ diameter drums

Nov 11, 2020 The drying drum is the heart of a rotary dryer, and the place where the drying gas and wet material are brought into contact. The material is showered through the air by rotating the drum. As the drum rotates, lifters mounted on the shell wall carry material up to the top, where it drops as a continuous curtain as the air passes through it

May 16, 2020 The rotary dryer’s drum is a slightly angled and rotatable cylinder with wet material entering from one end up and dry material collecting from the other end down. Hot air enters at the inlet or outlet end and exits at the top of the other end. The barrel is equipped with a forward-running plate, which makes the material to be continuously run up and down in the process of turning the barrel

Energy-efficient rotary drum dryers. A drum type heat of compression dryer offers an energy-efficient way to produce dry air. It’s a perfect match for your oil-free screw or centrifugal compressors. It uses the heat generated in the compression process to regenerate the desiccant. This heat is typically wasted in twin tower drying technologies

Jan 16, 2019 Rotary dryers, called the “workhorse of chemical dryers”, belong to the most widely used class of continuous dryers in process industries. These dryers are suitable for relatively free-flowing, non-sticky and granular materials; for example, almost all types of crystals after crystallization and washing. Typical applications of rotary dryers are in drying o table salt, sodium sulphate

Another study of a combined conduction–convection type rotary drum dryer was made by Regalado and Madamba (1997) on thermal efficiency. The fresh ambient air forced inside the drum in a counter flow direction of grain brought evaporative cooling of the hot grain as shown by the increase in moisture reduction whenever air velocity was increased
