Rotary drum dryer play a crucial role in the production process of biomass pellets, helping to "industrialize" and upgrade the industry by improving product quality, enhancing production efficiency, and reducing energy consumption. Here are the specific ways:

1.Improving product quality:

The moisture content of biomass raw materials is usually high. If not dried before use in production, it will lead to problems such as low thermal efficiency and insufficient combustion of biomass pellets. rotary drum dryer can dry the raw materials to 12%-15%, resulting in pellets with a calorific value of 4200-4800 kcal/kg and a ash content of ≤1%, improving the combustion performance and stability of the pellets, and meeting the market demand for high-quality biomass pellets.

2.Increasing production efficiency:

Some advanced rotary drum dryer are equipped with components such as spiral blades, which can stir and flip the materials, improving the internal particle mixing effect and accelerating the drying speed, thereby enhancing overall production efficiency and helping enterprises expand production scale and meet the growing market demand.

3.Reducing energy consumption and costs:

Newer rotary drum dryer have significant energy-saving effects. For example, the three-layer single-channel rotary drum dryer is 30%-50% more energy-efficient than ordinary dryers. The cylinder has a self-insulation heat efficiency of over 70%, effectively reducing heat loss and lowering energy consumption. Additionally, some dryers can be equipped with energy-saving new type hot air furnaces, reducing energy consumption by about 30% and electricity consumption by 20%, significantly reducing production operation costs and enhancing the economic benefits of enterprises, strengthening the competitiveness of the industry.

4.Promoting production automation:

Modern rotary drum dryer often have intelligent control functions, enabling one-click operation, automatic adjustment of operating parameters, and automatic adjustment of parameters such as drying time, temperature, and material flow according to the moisture content of raw materials and production requirements, ensuring that the drying machine is always in the best operating condition, reducing manual intervention, improving production stability and consistency, and facilitating the development of the biomass pellet industry towards automation and intelligence.

5.Complying with environmental protection requirements:

rotary drum dryer are equipped with complete dust removal and purification devices, such as cyclone dust collectors and wet dust collectors, which can effectively treat the dust-laden moisture generated during the drying process, ensuring compliance with emission standards and reducing dust and other pollutant emissions, meeting environmental protection requirements. Moreover, some dryers can utilize waste heat for drying, reducing energy demand while reducing emissions, promoting the green and sustainable development of the biomass pellet industry.
