The multi-layer belt dryer is a highly integrated drying equipment, consisting of multiple single-stage belt dryers connected in series in a sealed drying chamber, with up to 15 layers, commonly used 3-5 layers. This design allows the drying medium to flow through the material layer more efficiently, improving the overall drying efficiency.
The conveying speed of each layer will be adjusted according to the characteristics of the material and the process requirements, especially the last few layers, the conveying speed is lower, which makes the material layer thicker. This design helps to allow most of the drying medium to flow through the first few layers of thinner material, further increasing the overall drying efficiency.
The separators set between the layers help to guide the directional flow of the drying medium, ensuring that the material can absorb heat and moisture evenly during the drying process, and achieve better drying results.
The multi-layer belt dryer consists of several parts, including an insulated chassis, a conveyor chain mesh belt, a chain tensioning device, a dehumidification system, a transmission device, an anti-stick steering conveyor belt, and an indirect heating device. These components work together to ensure the stability and efficiency of a multi-layer belt dryer.
During operation, the lower discharge conveyor belt generally extends 2-3 meters out of the box outlet, providing a convenient space for workers to sort out deformed and imperfect products during the drying process. This design not only improves the production efficiency, but also ensures the quality of the product.
In general, the multi-layer belt dryer is an efficient and stable drying equipment, which is suitable for the drying needs of various materials. Through the design of multi-stage series and layer spacer, it realizes the uniform drying of materials and the operation process with high efficiency.
