BMH Chronos Richardson are now supplying Air Swept Tubular (AST) Dryers into a diverse range of European material processing sectors. The AST Dryer is believed to be the most versatile dryer on the market today, capable of drying a diverse range of materials varying from 95 percent liquid scurries to fine powders with only minor adjustments to system settings. It is considered to provide a flexible and efficient alternative to rotary drum and fluid bed drying systems.

The AST Dryer's novel agitation design mixes hot air with the wet product entering the dryer inlet, reportedly reducing the drying time and breaking up any lumps. On applications such as slurry drying and waste product reclamation projects the AST Dryer can, it is claimed, reduce slurry moisture contents from 95 percent to 1 percent in a single pass. Innovative adjustable paddles and air dams facilitate changes to retention times to allow for variations in the drying process.

The patented agitator design is said to incorporate intense mixing and grinding actions. It is also claimed that the system's single pass operation provides optimum energy efficiency, less energy is used due to the high heat transfer coefficients achieved through high velocity and product agitation. Designs can be customised to an individual product's handling requirements. The dryers are described as having a rugged design for trouble-free long-term operation. Flexible retention times are believed to enable difficult to dry products to be successfully handled, it is also stated that fine materials can also be separated from coarse materials. Lower exit temperature and residence time minimise product degradation.
