A method and apparatus for heating a plurality of bottle caps simultaneously. The apparatus comprises a housing with an air blower, resistance heaters and a thermocouple positioned within its interior. Air blown through the interior is heated by resistance heaters and travels through air ducts positioned at the opposite end of the housing. The air duct is positioned in spaced relation to the interior of a hopper and has a series of apertures through which heated air is injected into the hopper's interior. The flow rate of the air is sufficiently high so that the heated a ir agitates the caps within the hopper and is evenly distributed throughout the interior of the hopper. The temperature of the air is controlled so that the caps are warmed to a temperature within the range of 88.degree.F to 92.degre e.F.
