A vessel (10) for a feedstock that is to be heated using radio frequency electromagnetic radiation (EMR), the vessel being adapted for rotation about an axis that passes through the vessel and having an inlet aperture through which the feedstock may be introduced into the vessel and a wall (16) for retaining the feedstock in the vessel, wherein the wall (16) has at least one vent for venting gases released by the feedstock, the at least one vent being so formed that rotation of the vessel about the axis prevents the feedstock from entering the vent, thereby retaining the feedstock in the vessel. Also heating apparatus (50) comprising such a vessel (10), means (54) for introducing a feedstock into the vessel, means (56, 62, 64, 66) for discharging the feedstock from the vessel, a source (58, 80) of EMR and drive means (75, 200, 202) operable to rotate the vessel (10) about an axis that passes through the vessel. Also a method of heating a feedstock using EMR, comprising the steps of delivering a feedstock into such a vessel, directing EMR at and/or introducing EMR into the vessel and rotating the vessel so as to tumble the feedstock. |
