CHEMICAL ENGINEERING LABORATORY 3, CE 427 DRYING
Drying involves the final removal of relatively small amounts of water, or in some cases solvent, from a material. Excluding the partial drying of a solid by mechanical means, for example, by squeezing, all drying operations depend upon the application of heat to vaporize the volatile constituents. All solidBEST PRACTICE MANUAL DRYERS,The rate of drying is determined for a sample of substance by suspending it in a cabinet or duct, in a stream of air from a balance. The weight of the drying sample can then be measured as a function of time from wet product to bone dry product. The curve of moisture content as a function of time, similar to fig 2.1, can be plotted.
The Drying Curve, Part 1 2002-09-01 Process Heating
Sep 01, 2002· Drying occurs in three different periods, or phases, which can be clearly defined. The first phase, or initial period, is where sensible heat is transferred to the product and the contained moisture. This is the heating up of the product from the inlet condition to the process condition, which enables the subsequent processes to take place.Mineral Drying FEECO International Inc.,Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product.
