The present invention relates to a new device and a way to assemble such a device for both cooking and drying organic material in the process of making meal. The device of the present invention has a large area for heat exchange and scrapers which stir the material in the container rather than transferring it around in circles. The method of assembling the device allows an accurate and convenient assembly so that the scrapers thoroughly scrape all inner surfaces of the device.

The object of the invention is a horizontal paddle dryer that is used for normal or vacuum drying of soaked substances that are in the form of dry powder mixtures or granulates in a manufacturing process and are soaked and mixed (normally with solvents) due to technological needs. Once drying is completed, the interior of the dryer needs to be washed due to various types of substances that differ from each other in content and properties. The construction of the horizontal paddle dryer of the invention allows simple and effective washing of the horizontal paddle dryer without an additional removal of washing heads during the washing of the dryer. The horizontal paddle dryer of the invention has a specially shaped interior wall (1) of the drum (2) that passes on the upper part through two surfaces (1a, 1b) that extend tangentially to the interior wall (1) into a horizontal final surface (1c) of the internal wall (1), such that a slightly concave part is created in the interior of the drum (2) in the wall (1), in which concave part retractable washing heads (3) are arranged that do not hinder functioning of the rotor (4) with paddles (5) either during drying or during washing.

An apparatus for processing a biomass material includes an evaporator and a dryer. The evaporator includes a vertically orientated evaporator housing with a heatable casing, which encloses a rotationally symmetric evaporation chamber and a drivable evaporator rotor shaft, including a central evaporator rotor shaft body and wiping units. The wiping unit includes wiping elements designed for wiping inside the evaporator housing casing. The dryer includes a housing with heatable casing and encloses a drying chamber and a drivable dryer rotor shaft for distributing the biomass material inside the casing and conveying the biomass material toward the dryer outlet and includes a central dryer rotor shaft body and rotating elements over the circumference thereof, and rigidly mounted on the dryer rotor shaft body.

A method for continuous thermal separation of a substance being fed into a treatment chamber is performed within a vessel. Besides the vessel, the apparatus includes a heating device with an external heat source and a rotary mechanism with an external rotary drive. The heating device and the rotary drive are mutually operated such that a resulting operational temperature T.sub.op is obtained within a volume V.sub.p near an inner surface of the vessel which is equal or higher than an evaporation temperature T.sub.c of at least one liquid constituting part of the substance.

A separation apparatus for continuous thermal separation of a substance is fed into a treatment chamber. The substance includes two or more components where at least one of the components is evaporable at an evaporation temperature (T.sub.e). The separation apparatus includes a vessel including a vessel wall with an inner surface enclosing the treatment chamber having a length I.sub.C, 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 from the treatment chamber, a second outlet for releasing evaporated parts of the substance from the treatment chamber, and a rotary mechanism. The rotary mechanism includes a rotatable axle arranged within the treatment chamber having an orientation directed along the treatment chamber's length L and a mixing device fixed to, and extending perpendicular from, the rotatable axle. A radial outermost part of the mixing device includes a plurality of radially separated mixing protrusions, a rotary drive operatively connected to the rotatable axis, and a heating device arranged outside the treatment chamber. The heating device is configured to transfer thermal energy to a minimum peripheral volume (Vp) of the treatment chamber via the inner surface. The minimum peripheral volume (V.sub.p) is defined as a volume between the inner surface and outer radial boundaries of the mixing device. The mixing device includes a plurality of rotary discs fixed with axial offsets to the rotatable axle. The heating device and the rotary drive are configured such that, when both the heating device and the rotary drive are operated at their respective operational input powers (P.sub.hd, P.sub.rm), a resulting operational temperature (T.sub.op) is obtained within at least part of the minimum peripheral volume (V.sub.p) which is equal or higher than the evaporation temperature (T.sub.e).
