Abstract:To Sydney for the provision of practical dry dryer, a kind of tunnel dryers was designed。 electric heater heating system uses hot air box, clean, hot air temperature can be set according to variety and Sydney automatic adjustment; air supply system centrifugal fan increases air-flow devices, adjustable speed; the tunnel by a combination of thermal insulation shell. Test proved that the drying machine can be adapted to different drying fruit traits. The industrialization of fruit production, makepost-harvest handling of fruit to achieve the mechanization and automation technologies possible. And to increase agricultural efficiency and income of the farmers, with great economic and social benefits. Therefore, the design of dried fruit ideal dryer is also important.
