Belt dryer for food and pet food products

Optimize drying processes with customizable belt dryers, engineered to handle robust moisture removal for a variety of products from food to renewable materials, ensuring consistent product quality and improved operational efficiency in your production line.

Efficiently Dries and Handles Diverse Industrial Materials

The Belt Dryer Type BTF-S from STELA Laxhuber GmbH stands out by offering an innovative stage-based drying system tailored for industries such as agriculture, food processing, and renewable fuels. This dryer uses a series of belts within individual housings, facilitating high air velocities and significant water evaporation, crucial for efficiently drying products like cornflakes, pet kibble, and biomass pellets.

With its customizable belt lengths and zoned air flow, the BTF-S supports continuous and stage operations, optimizing bulk handling by varying conveyor speeds. This increases both operational efficiency and product quality. The dryer boasts a capacity to handle a wide range of materials from granules to powders, making it suitable for versatile use cases like recycling materials and drying sewage sludge.

Energy efficiency is a key feature, with the option for exhaust air recycling and various heating methods including gas, oil, or biomass boilers. Constructed with maintenance in mind, the machine simplifies cleaning processes and allows significant flexibility in material handling through swing and vibratory conveyors.

STELA supports customization to meet specific process requirements, ensuring the belt dryer seamlessly integrates with existing production lines, particularly beneficial for operations focused on reducing emissions and optimizing resource usage.
