• Most versatile and widely applied dryers
• Used to dry food, chemicals, and pharmaceuticals
• Materials vary in density and viscosity such as dilute solutions, heavy liquids, or pasty materials
• Effective for heavy sludges that become saturated and deposit salts
• Products sensitive to high temperatures can be dried successfully because exposure to temperatures above the boiling point is restricted to just a few seconds
• Movable drum permits complete control of product film thickness
• Feed may be accomplished via perforated tube trough, pendulum, or specially engineered devices
• Can be equipped with externally controlled full or partial enclosures to protect personnel when drying toxic, dusty, or flammable products

• Wet feed is introduced to nip by various methods including perforated pipe, pendulum feed or mechanical trolley
- Reservoir of fluid is formed between drums and contained within endboards fitted against end faces of drums
• Wet feed level may be varied as required
• Liquid is heated to boiling point and partially concentrated by hot drum surfaces
• Feed is deposited as film on both drums

Benefits of the company's products are numerous, including:

• Drying takes place within a single revolution of the drums
• Dried material is removed by adjustable knives
• One drum is movable to enable thickness of product film to be controlled
• Thickness of film can be modified to produce product ranging from flakes to powder
