The latter is incorporated immediately below the conveying surface, e.g. in an opening in the conveying element. Pref. the conveying element (2) comprises a sluice wheel between inlet and outlet lines (4, 5) mounted on a rotary shaft (7). The periphery of the wheel is provided by 4 identical concave surfaces offset from one another by 90 degrees, with an electric heating element (8) immediately beneath each. The connection leads (9) for the heating elements (8) are fed through a central opening in the shaft (7), with a brush connection to a stationary voltage supply.</p> |
