drying: principles, applications, and design

March Adjustment and control of moisture levels in solid materials through drying is a critical process in the manufacture of many types of chemical products. As a unit operation, drying solid materials is one of the most common and important in the chemical process industries CPI , since it is used in practically every plant and facility that manufactures or handles solid materials, in the form of powders and granules. The effectiveness of drying processes can have a large impact on product quality and process efficiency in the CPI. For example, in the pharmaceutical industry, where drying normally occurs as a batch process, drying is a key manufacturing step.

Post a Comment. Home Equipment Production. Principle of Tray Dryer Tray dryer is widely used for material dying in pharmaceutical manufacturing. Its drying process is based on circulation of got air trough the chamber having material. A tray dryer is a convectional drying equipment with enclosed insulated chambers and trays placed on top of each other in a trolley. The driers are used in processes where drying and heating are a crucial part of the industrial manufacturing process such as in the food products, pharmaceutical, dye stuff, and chemicals manufacturing among others.

Selected Definitions Drying: It can be defmed as an process in which the liquid, generally water, present in a wet solid is removed by application of heat and fmally a liquid free solid product is obtained. Bound Water: It is the moisture content of a substance that exerts a equilibrium vapor pressure lower than that of the pure liquid at same temperature. Unbound water: It is the moisture content of a substance that exerts a equilibrium vapor pressure equal to that of the pure liquid at same temperature. Free Moisture: It is the moisture content of the solid in excess of the equilibrium moisture content Moisture content: It is measured by ratio of weight of dry sample to ratio of weight of water in sample EqulUbrium Moisture Content EMC : It is the moisture content of the solid when in equilibrium with the given partial pressure of vapor in the gas phase. Fluidized State: It is the state in which the granules are suspended in the air stream and rise from the bottom.
