Abstract (en)
[origin: EP0272854A2] A hot gas convective drying apparatus is provided with a plurality of nozzles for directing hot gas onto material to be dried and with radio frequency heating means adapted to create a radio freqeuncy field in the region through which the material to be dried travels. The electrode means of the radio frequency heating means comprises a pair of spaced perforated plates (11,12) between which the material (10) to be dried passes and with which are associated the hot gas directing nozzles. Alternatively the electrode means is a single perforated plate (11b) with an opposed array of individual hot gas directing nozzles.
