As part of the biomass pellet production process, the use of dryers is of great importance. It affects not only the moisture content but also the quality and stability of pellets. Due to its unique advantages, the Single Rotary Drum Dryer has become one of the most popular members of the dryer family.
How Dryers Contribute to Biomass Pellet Production
In the production process of biomass pellets（Please click here to view an overview of the entire pellet machine production line）, the dryer is an essential link. Biomass pellets that have not been dried are too humid to be suitable for industrial combustion and power generation. Using a dryer, it is possible to effectively remove the moisture in biomass granules. As a result, granules can reach an appropriate moisture content and their quality and durability can be enhanced.
The structure and working principle of dryer
The single rotary drum dryer is a long, mounted cylinder that rotates slowly about its axis. The drum is insulated to cut heat loss and has a jacketed design to facilitate heat transfer. At one end of the drum, a burner generates hot air, which enters the drum through a series of perforations. At the other end, the dried biomass exits through a discharge chute.
The single rotary drum dryer operates on the principle of convective heating. As the drum rotates, the wet biomass particles are lifted on the hot air current and dropped back onto the drum’s surface. This repeated lifting and falling process accelerates the evaporation of moisture from the biomass particles. The rate of drying can be controlled by adjusting the temperature and velocity of the hot air stream.
Advantages Of rotary drum dryer
The single rotary drum dryer offers several advantages over other drying methods:
- High-capacity: The drum design allows for efficient processing of large quantities of biomass particles.
- Efficient drying: The convective heating method dries the biomass quickly and uniformly, reducing processing time.
- Reduced fuel consumption: The dryer’s efficient design ensures that the supplied heat is used effectively, resulting in lower fuel costs.
- Low maintenance: The simple design and robust construction of the dryer require minimal maintenance, reducing operating costs.
- Flexible operation: The dryer can be operated continuously or intermittently, depending on production requirements.

Frequently Asked Questions
What is the difference between a drum dryer and a roller dryer?
The drum dryer is an indirect type dryer in which the milk to be dried is maintained in a thin film on a rotating steam heated drum.
How efficient is a drum dryer?
Its high thermal efficiency translates to steam consumption of approximately 1.4 kg for each kilogram of water evaporated. Drum drying is environmentally friendly as well, with low levels of dust emission, thus avoiding the need for complicated filter installations and additional waste.
Does the dryer use a lot of electricity?
Dryer Wattage Explained: How Much Electricity Does a Dryer Use? Electric dryers use anywhere from 1800 to 5000 watts of energy, on average, dependent on the load and cycle configurations. This equates to about 1.8 to 5 kWh of electricity. Whirlpool dryers typically require 2100 watts of energy.
