What is Single Drum Rotary Dryer?
Single drum rotary dryer is a traditional mature single-cylinder drying equipment, widely recognized for its high stability and cost performance. Different from multi-pass complex dryers, it adopts an integrated single-drum structure with fewer accessories and lower failure rate. It is specially developed for users with limited budget and medium and small drying output demands.
This industrial single cylinder dryer can process various loose biomass materials, including wood sawdust, wood shavings, wheat straw, corn stalk, alfalfa pasture grass and other agricultural and forestry wastes. Through continuous hot air heat exchange and material flipping, it realizes uniform dehydration and drying. The finished materials meet the production standards of biomass pellets, briquettes, animal feed and organic fertilizer, being the preferred drying equipment for small factories, farms and individual recycling projects.

Working Principle & Production Process of Single Drum Rotary Dryer
Working Principle
The single drum rotary dryer adopts inclined rotary structure and hot air convection drying principle. Wet biomass materials are evenly sent into the single cylinder drum through the feeding device. With the slow rotation of the drum, the internal lifting flights continuously lift and scatter materials to form a uniform suspended material layer. Materials fully contact with high-temperature hot air for sufficient heat exchange, so that internal moisture evaporates rapidly. Water vapor and fine dust are discharged and purified through the dust removal system, and the dried low-moisture materials are stably discharged from the outlet to complete the whole drying process.
Standard Production Flow
Wet Material Feeding → Single Drum Hot Air Drying → Dust Removal & Purification → Cooling → Dry Material Discharging → Pelletizing / Briquetting / Storage
