photovoltaic dryer with dual packed beds for drying

Advances in Food Process Engineering

Intermittent drying can be applied to any direct dryer or batch dryer such as for example a tray dryer convective dryer conveyor dryer fluidized-bed dryer and spouted-bed dryer Mujumdar (1991) identified and proposed for the first time the use of multiple modes of variable levels of heat input simultaneous or consecutive as well as cyclical variations in velocity or operating pressure

Method and apparatus for generating a low tar renewable fuel gas from biomass and using it in other energy conversion devices many of which were designed for use with gaseous and liquid fossil fuels An automated downdraft gasifier incorporates extensive air injection into the char bed to maintain the conditions that promote the destruction of residual tars

Fluid Bed Dryer

In a fluid bed dryer used for powder drying initially the air is sucked inside from the surroundings with a fan run with electric motor inside the dryer The air then passes through heating system within the dryer and gets heated up This hot drying air is then made to flow through bed of the moist materials that are laid on shaking perforated steel bed This air is introduced with required

Synthesis of Polyacetylene

A graphene-based or carbon-based aerogel is a three-dimensional (3D) solid material in which the carbon atoms are arranged in a sheet-like nanostructure In this study we report the synthesis of low-density polymer-modified aerogel monoliths by 3D macroassemblies of graphene oxide sheets that exhibit significant internal surface areas (982 m2/g) and high electrical conductivity (∼0 1 to 1
