A solar powered food dryer that may be used indoors is provided when a solar heated convection column is used to produce a draft of air and by means of this draft to draw air from a solar collector through a food drying chamber in such a way that the hot air from the collector is drawn over the food in the drying chamber and hot air ducting of the airstream provides a means of remoting the drying chamber to a sanitary and convenient place while leaving both the air heater and the draft generating convection column in a place exposed to solar radiation.
