Abstract

1,211,024. Microwave heating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 10 Feb., 1969 [9 Nov., 1967], No. 51099/67. Heading H5H. Apparatus for heating sheet material or discrete objects or particulate material using microwave energy comprises an applicator 3 adapted to propagate the energy as a slow wave only in a direction parallel to the direction of movement AA of the material 2 through a heating zone. A loss-free conveyer belt 1 of polypropylene conveys the material 2 through two halves 3a, 3b, of the applicator or, alternatively, a stainless steel belt 1<SP>1</SP>, Fig. 5 (not shown), carries material beneath an applicator 3<SP>1</SP> of similar structure to part 3a. Applicator part 3a has a plurality of channels A-F, each #/4 deep, with horizontal coupling slots S1-S4 therebetween and vertical slots V1-V3 to prevent propagation of energy transverse to the direction of material movement, the slots V1- V3 being 3#/8 apart. Energy is coupled from the waveguide W into channel A through slots L1-L4. Channels X, X<SP>1</SP>, prevent leakage from channels A, A<SP>1</SP>, to the outside of applicator 3 by acting as quarter wavelength chokes. In an alternative, the applicator is fed at the centre to propagate slow waves in opposite directions.
