ABSTRACT:
A method of producing refreshable dry food comprises the step of placing unfrozen raw food in a vacuum chamber; reducing the pressure in the chamber to a value within the range 1 Torr to 5 Torr thereby reducing the temperature to a value within the range of -10.degree. C. to 0.degree. C.; irradiating the food with infrared energy having a wavelength of at least 5 microns; and terminating the irradiation when the food reaches a temperature in the range +5.degree. C. to +40.degree. C. whereby the food is dried before its texture is adversely affected.
