Tray & Bed Dryer

Details:

• In small, dryers the material is placed on trays, which slide into the drying cabinet, while in large installations the interior may be designed for the wheeling in of trolleys containing the trays. The simplest form of heating places the sources of heat (e. g. a steam coil or electrical coil) at floor level and relies on natural convection. Fans provide a forced circulation of air across the trays. Air flows in axle direction over each shelf in turn. The wet material spread directly on the shallow trays resting on the shelves. Electrical elements (heater) or steam heated pipes are positioned so that air is periodically reheated after it has cooled by passage over the wet material on one shelf before it passes over the material on the next shelf. Tray dryer is a type of Fixed Bed Dryers i.e., the bed of the material to be dried is stationary.

• Fluid Bed Dryer is designed for rapid and uniform drying of crystal, powders and medium size pellets. A fan draws fresh air and passes the air through a filter and is heated to produce warm air either by electric heaters or by steam. The hot air is passes through the product container having diffuser plates and sieve. Due to the air stream the wet product gets fluidized. The material gets surrounded by hot air which gets dried due to heat transfer. Moist air passes through a filter bag and exhaust dust.

• Drying is an essential unit operation in a variety of chemical process industries (CPI) sectors. Food, pharmaceuticals, chemicals, plastics, timber, paper and other industries use drying equipment to eliminate moisture during product processing. Most dryers are classified as direct dryers, where hot air (at near atmospheric pressure) is used to supply the heat to evaporate water or other solvents from the product. Another important dryer category, vacuum dryers, involves the use of a reduced-pressure atmosphere to surround the product. Drying is among the most energy-intensive unit operations, due to the high latent heat of vaporization of water and the inherent inefficiency of using hot air as the (most common) drying medium. Depending on the specific product attributes required, different industry sectors require different types of drying technology. Drying high-value products that are likely to be heat-sensitive, such as food, pharmaceuticals and biological products, demands special attention. When dried by convection at higher temperatures, these heat-sensitive products degrade, change color and appearance and have lower vitamin or nutrient content. Vacuum dryers offer an alternate path. This article discusses the operation and selection of vacuum dryers, and provides examples of applications in which vacuum drying is used.
