Ventilex belt dryers are highly efficient and have low energy consumption. The combination of temperature cycles and drying times can be adjusted as necessary to control the physical properties of the final product. The internal transport consists of one or more stainless steel tapes. Because the drying air flows through the belt, the heat exchange is complete and results in high production efficiency and exceptional final product quality.
The raw material is evenly distributed through the conveyor belt by means of a suitable auxiliary mechanism, such as a distributor, a vibrating belt, a sprayer, or granulator. The drying tunnel is divided into zones, each maintaining a different temperature. Each zone has a system of air heating and recirculation, and if necessary, a system of extraction of humid air. As the conveyor belt passes through each zone, hot air passes through the material from top to bottom, then bottom to top, to produce a uniformly dry product.
Depending on the product, the tunnel may be equipped with a cooling section and a vibration device at the output to lower the temperature of the final product for convenient and timely packaging.
