Single Drum Dryer with Applicator Rolls
The wet product is applied to the drum by means of applicator rolls. According to the number of the applicator rolls used the layer formed on the drying drum is thicker or thinner. This arrangement is suitable for the processing of pulpy or pasty products.
Typical applications are: Cereal based breakfast foods, Baby-food products, Pre-gelatinised starches, Fruit pulp and pastes, Potato flakes.
Twin Cylinder Dryer with Nip Feed
The material to be dried is pumped, either directly or through spray nozzles, into the nip formed between two drying drums. This is the oldest and simplest form of drum dryer. The thickness of the product film may be varied by adjustment of the gap between the drying drums or cylinders.
Typical applications are: Drying of Spent Yeast, Milk products, Detergents, Dyestuff manufacture.
Single Drum Dryer with Applicator Roll
This is a more specialised type of drying, for example in the Chemical Industry. The applicator roll is located underneath the drum dryer and dips into the product. A liquid film is then transferred to the drying drum.
Typical applications are: Animal based glue, Gelatine, Pesticides.
Dip Feed Drum Dryer
One of the most basic forms of the drum dryer, where a film of the product to be dried is picked up on the surface of the dryer drum as it rotates through a feed tray mounted below. The feed tray may be cooled or fitted with a re-circulation system to prevent overheating or settling out of product from suspension.
Typical applications are: Drying of cereals, Spent Yeast.
