In a belt dryer, hot air is circulated through the material bed, resulting in efficient drying. Depending on the actual needs, the drying oven can be designed as a single chamber or divided into multiple drying sections. Each section is equipped with an air heater and circulation fan, as well as a fresh air inlet and exhaust facility. This modular design ensures temperature control in each zone to optimize drying efficiency.
There are many types of belt dryers, covering various types such as single-channel, multi-stage single-channel, multi-channel conveyor paddle type. It is also available in a variety of structural forms, including flat, chain, mesh and slat. In order to improve drying efficiency, we have adopted a series of strategies, such as adjusting the direction of airflow, using double-layer heat shields, ensuring that the dryer housing is well sealed, distributing air evenly, using variable speed conveyor drives, and enhancing air circulation.
Feeding methods are equally varied, such as oscillating rakes, vibratory and apron feeders. At the same time, we can also equip equipment such as pellet mills and extruders as needed. In addition, special features such as integral or individual cooling sections, explosion protection, thermal**, exhaust gas purification, etc., are also advantages of belt dryers. These features ensure the temperature control and safety of the product.
Belt dryers offer significant advantages in certain applications. Especially at low temperatures, it is capable of continuously drying temperature-sensitive and sugary products. The vacuum dryer consists of a vacuum chamber and a food-grade conveyor belt that is heated by a hot plate heated by steam or hot water. The product is unfolded on a moving belt and moved with the hot plate, allowing for drying. The dried product is produced at the other end of the vacuum belt dryer.
In conclusion, belt dryers are ideal for many industries due to their efficiency, flexibility, and reliable performance. Whether it's food, pharmaceutical, or other industries that require dry handling, belt dryers provide a stable and efficient solution.
