A drum dryer can produce products at a rate between 5kghr21 m22 and 50kghr 21 m 2, depending upon type of foods, initial and ﬁnal moisture content, and other operation conditions. Drum dryers are classiﬁed into single drum dryer [Fig. 1(a)], double drum dryer [Fig. 1(b)], and twin drum dryer. A double drum dryer has two drums that revolve

The rotary dryer also known as tumbling dryer is an equipment employed to minimize the moisture content of feed materials by bringing it in direct contact with a heated gas. it consists of an inclined long drum or cylindrical shell often fitted with internal flights or lifters; rotated slowly upon bearings through which the material to be dried ...
If your rotary drum dryer is struggling to achieve uniform moisture content, and is still being operated inside design criteria, it may be time to consider a new flighting design. however, if your dryer used to process the same material at your current rates just fine, you may have flight damage – either from fire, rocks, or a slug of heavy ...
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.

Apr 27, 2007 abstract the effectiveness of the rotary drum drying process depends primarily on the contact between the cascading particles and the drying gases within the drum. this paper considers first the factors which contribute to the cascade pattern and which influence the design of the lifting flights which distribute the particles in the top half of the drum.
And is transported into a rotary dryer (typically gas- or oil-fired). dryers are equipped with flights designed to shower the aggregate inside the drum to promote drying efficiency. as the hot aggregate leaves the dryer, it drops into a bucket elevator and is transferred to a set of
Another type of direct dryer that is seeing increased use in the u.s. and europe is the belt dryer. this is typically a lower temperature system compared to a rotary drum system. the heat supply is usually a fuel-burning furnace, but in contrast to the rotary drum system, the system exchanges its heat to a thermal fluid, hot water
What are smart rotary drum dryer designs do we use for high drying efficiency? our rotary dryer consists of heat resource, feeding machine, rotating cylinder, transmission, discharging device and induced draft fan. we use advanced concept on designing, making the roller dryer works better.
