ABSTRACT:
An energy efficient dryer for solid foods with moist interiors uses both thermal convective and microwave drying processes. The dryer will run on a fuel such as natural gas alone, and requires no input of electricity because it utilizes a single prime mover to produce both thermal energy and electrical energy, such as an internal combustion engine, which both provides heat for convective drying, and drives a generator which produces electricity for conversion to microwave power. Moist food is fed by an air pervious belt or other means through a first zone in which it is dried by thermal convection, and then through a second zone in which it is dried by microwave radiation.
