Drying - Wikipedia
WEBDrying is a mass transfer process consisting of the removal of water or another solvent [1] by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging products.

What are the different industrial drying technologies? - SAIREM
WEBThe most common are sun drying, hot air drying, contact drying, infrared drying, freeze-drying, fluidized bed drying, and dielectric drying. Depending on the nature of the products to be treated, either foodstuff or industrial material, these methods prove to be more or less adapted.
Industrial Drying: A Guide to the Process, Equipment & More
WEBIndustrial drying is a complex process that requires careful consideration and expertise. Different types of dryers are available for specific industries, such as fluid bed dryers, tray dryers, or rotary dryers. The choice of equipment depends on various factors, including temperature control, light control, and humidity control.
Solids Drying: Basics and Applications - Chemical Engineering
WEBApr 1, 2014 · Based on the mechanism of heat transfer that is employed, drying is categorized into direct (convection), indirect or contact (conduction), radiant (radiation) and dielectric or microwave (radio frequency) drying. Heat transfer and mass transfer are critical aspects in drying processes.
Lesson 11. DRYING: PRINCIPLE, METHODS AND APPLICATIONS
WEB11.7 Types of Drying. a. Hot Air drying: It includes spray drying, tray drying, fluidized bed drying, etc. In spray drying a fine dispersion of pre-concentrated food (40-60% moisture) is atomized to form fine droplets and then sprayed into a co-or counter-current flow of heated air at 150-300 C in a large drying chamber. Tray driers consist of ...

Drying Technology - an overview | ScienceDirect Topics
WEBDrying types can be classified by either the mechanism of heating or mechanism of vapour transport. Air drying requires a high temperature air which supplies the heat and removes the water vapour, whereas vacuum drying uses a reduction in pressure to remove the vapour ( Chen and Mujumder, 2009 ).
