Abstract

1,053,012. Preserving food with microwave heating. CRYODRY CORPORATION. Feb. 2, 1965 [Feb. 3, 1964], No. 4567/65. Heading A2D. [Also in Divisions F4 and H5] In an apparatus for treating a substance with microwave energy, the substance is passed through a horizontal microwave chamber on, for example, a glass fibre conveyer belt or, in the case of liquid, powdered and particulate substances, the substance is allowed to fall through a vertical microwave chamber, while in each case a partially dry, temperature controlled, gaseous atmosphere is maintained in the chamber. A suitable system for supplying the controlled atmosphere to the microwave chambers is described and illustrated, and comprises means for heating or cooling and optionally drying either filtered air or a gas such as nitrogen. Examples are given of the use of the apparatus for drying potato, apple and bacon slices, and for the final drying of potato chips after conventional deep frying. The use of the apparatus for the preliminary blanching or cooking of foods prior to freeze drying is also mentioned.
