ABSTRACT:
An apparatus for sterilizing food packaged in flexible pouches in a contius process employing microwaves for heating the food within the sealed flexible pouches to sterilizing temperatures. The pouches of food are conveyed thru the apparatus between a pair of conveyor belts which are permeable to microwaves and which comprise a layer of thermal insulation which is also permeable to microwaves. The pouches are also permeable to microwaves. The apparatus is pressurized to prevent bursting of the flexible pouches at the high sterilizing temperatures attained.
