Abstract (en)
[origin: EP0033911A1] 1. Apparatus for the capacitive high-frequency heating of lump material containing asphalt or tar, in particular of material which comes from road surfaces and which is to be re-used, to a final temperature of 170-200 degrees C, characterized by a first capacitive continuous furnace (1), in which the lump material (4) carried between the electrodes (12, 13) can be heated at 80-100 degrees C until it is plastically deformed, a following mechanical levelling device (2), in which the material (4) carried can be deformed to have a substantially uniform layer thickness (h), and a following capacitive continuous furnace (3), in which the material (4) which is at a substantially uniform distance (b) from the upper electrode (32), can be heated to the final temperature.
