What is dryer machine belt？
The belt dryer machine is a continuous drying equipment that can reduce the moisture content of materials stably, evenly and energy-saving. Unlike traditional drying equipment, it uses a circulating conveyor belt to transport material to a hot air circulation channel, achieving a continuous and automated drying process, reducing manual labor and improving production efficiency.
In the pellet production line, the dryer belt plays a vital role. Whether biomass pellets or feed pellets, they often retain a high moisture content after pelleting, which can affect pellet hardness, storage stability, and product quality.
A belt dryer provides a controlled drying environment for pellets. Material is evenly laid on the conveyor belt, and hot air is gently and continuously passed through the material layer, achieving uniform drying and preventing cracking or overheating. This ensures that the finished pellets are strong, durable, and easy to store and transport.
Although its main application is animal feed pellet production line or biomass pellet production line, it can also be used to dry agricultural product slices, biomass fragments, some chemical pellets and other materials.

how does belt dryer machine work？
The belt dryer’s operating principle appears simple, yet it boasts exceptionally high drying efficiency and stability. The material is evenly spread onto a moving, multi-layered mesh belt through a feeding system. As the belt slowly enters the drying chamber, hot air penetrates the material from top to bottom or bottom to top, achieving a continuous, uniform drying process.
- The feeding system ensures even distribution of the material, preventing excessive or thin accumulation and ensuring consistent drying.
- The heating system can utilize electricity, steam, natural gas, or biomass as a heat source, flexibly adapting to varying factory energy requirements.
- The air circulation system maintains a stable, circulating airflow through fans and ductwork, ensuring efficient heat transfer and rapid moisture removal.
- The discharge system collects the dried material and transports it to cooling, screening, or packaging, ensuring a stable moisture content in the final product.
Throughout the entire process, the material remains in a gentle, controlled environment, preventing damage from localized overheating. This maximizes the preservation of the material’s nutritional content, appearance, and texture. This makes this equipment an ideal continuous drying solution for pellet production lines.

How it Ensures Efficiency and Quality in Pellet Production Line？
Belt dryer machine plays an important role in connecting the upstream and downstream of the pellet production line. Using a multi-layer mesh belt and hot air circulation design, it precisely dries high-moisture materials after puffing or pelleting. Whether it’s feed pellets or biomass pellets, drying them maintains an optimal moisture content, improving the efficiency and quality of subsequent processes.
In this 1.5-2 ton/hour fish feed manufacturing plant, each component of the equipment works in tandem to form a complete production process. The belt dryer, as the core equipment in the drying process, plays an essential role in ensuring feed quality and optimizing the production process. Next, we will delve into its specific application within this production line.
- Crushing: The raw materials first enter the crushing stage, where equipment such as a SFSP feed hammer mill breaks down bulky materials into a suitable particle size, allowing them to flow smoothly into the next stage.
- Mixing: The crushed raw materials are thoroughly mixed by animal feed mixer according to the formula to evenly distribute the nutrients in the feed, providing a uniform material for pelleting.
- Granulation: The mixed materials are fed into an floating fish feed extruder machine, where high temperature and high pressure gelatinize the starch and form pellets.
- Drying: The pellets contain a certain amount of moisture. A belt drying machine effectively removes this moisture, reducing it to a suitable storage range. This also makes the pellet structure more compact and stable, improving hardness and wear resistance, and reducing the adverse effects of moisture on nutrients, thereby ensuring the nutritional value and quality of the feed.
- Cooling and Screening: The dried pellets are hot and need to be cooled to meet subsequent storage and packaging requirements. After cooling, they are screened to separate out broken and oversized particles that do not meet the particle size requirements, ensuring that the pellets meet quality standards.
- Packaging: After cooling and screening, qualified pellets are conveyed by conveyor equipment to the animal feed bagging machine, where they are bagged and sealed, making the feed easier to store, transport, and sell, thus completing the entire production line process.
By configuring a belt dryer machine in the production line, it is not only possible to effectively reduce the moisture content of the particles and extend the storage period, but also to create better conditions for subsequent processes. Its efficient drying and energy-saving design ensures continuity and product quality throughout the production line, providing companies with stable and reliable production support.
