About radiant heat transfer 2/2 In case of using fires or flames, subsidiary facilities to take care of smoke and exhaust gas are necessary.However, it cannot avoid that power consumption and running costs get higher when electrical infrared or far infrared heaters are used. Running cost is one of the important factors when introducing a machine […]
About radiant heat transfer 1/2 Radiant is one of the types of radiation and often defined as radiation of especially electromagnetic waves.In dryer’s terms, radiant heat transfer suggests a type of heating using electromagnetic wave. It transfers heat energy directly to a material and not through any object like conductive heat transfer. Dryers use especially […]
About conductive heat transfer Conductive heat transfer is to heat materials through an object, such as a board, and the materials are heated and dried by the conductive heat transferred via the heated board.Convective heat transfer drying heats materials directly, however, conductive heat transfer drying heats materials via an object such as metal board. So […]
One of convective heat transfer typed dryers is box shape dryer.The important points of this type are how to blow the blast and how to put the materials, in other words how to contact the hot blast with the materials most efficiently and keep the hot blast as higher temperature as possible. A box shaped […]
About convective heat transfer For example, air moves upward when it becomes lighter by being wormed.As the result, surrounding cool air flow into the place where air being wormed and air convection occurred.This is the same for water and convective heat transfer takes place while wormed water move upward and cool water which was originally […]
