Apparatus for continuous thermal separation of a multi-component substance

A separation apparatus for continuous thermal separation of a substance being fed into a treatment chamber, the substance comprising:

• a vessel comprising a vessel wall with an outer surface and an inner surface enclosing the treatment chamber having a length lc, a height H and a width W;
• a substance inlet for feeding the substance into the treatment chamber;
• a first outlet for releasing non-evaporated parts of the substance;
• a second outlet for releasing evaporated parts of the substance;
• and
• a rotary mechanism comprising a rotatable axle arranged at least partly within the treatment chamber along the treatment chamber's length lc and a mixing device fixed to, and extending perpendicular from, the rotatable axle;
• a rotary drive operatively connected to or near an end of a rotatably axis;
• and
• a heater arranged outside the treatment chamber, wherein the heater is configured to transfer thermal energy via the inner surface to the treatment chamber,
• wherein the heater comprises an enclosure arranged around the vessel, such that a void is created between the outer surface of the vessel wall and an inner surface of the enclosure,
• wherein the enclosure comprises a heat inlet for feeding a heated fluid into the void and a heat outlet for releasing the heated fluid from the void,
• wherein the heat inlet and the heat outlet are arranged opposite each other, perpendicular to a direction of the rotatable axle.
