The Belt dryer is a commonly used continuous drying equipment, which is widely used in the drying of sheet, strip, block, filter cake, and granular in the processing of agricultural products, food, pharmaceuticals, and feed production industries. It is particularly suitable for stuffs with high moisture content, such as vegetables and traditional herbal medicine, for which high drying temperatures are not allowed. The machine uses hot air as the drying medium to continuously and mutually contact with those wet stuffs, let the moisture to disperse, vaporize, and evaporate with heat, resulting in fast drying, high evaporation intensity, and good quality of dried products.
It can be divided into single-layer belt dryers and multi-layer belt dryers. The source can be coal, electricity, oil, gas, or steam. The belt can be made of stainless steel, high temperature resistant non-stick material, steel plate, and steel belt. Under standard conditions, it can also be designed according to the characteristics of different stuffs, the machine with the characteristics of small footprint, compact structure, and high thermal efficiency. Especially suitable for drying stuffs with high-moisture, low-temperature drying required, and need a good appearance.
Large processing capacity
As a typical continuous dryer, the belt dryer is well-known for its large processing capacity. It can be designed with a width of over 4m, and multiple layers ranging from 4 to 9, with a length reaching tens of meters, it can process hundreds of tons of stuffs per day.
Intelligent control
The control system adopts automatic temperature and humidity control. It integrates temperature adjustable, dehumidification, air supplementation, and inner circulation control. The process parameters can be set in advance for automatic operation a whole day.
Even and efficient heating and dehydration
By using side section air supply, with large air volume and strong penetration, the stuffs are heated uniformly, resulting in good product color and same moisture level.
