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.

Disclosed in the present disclosure is a method for extracting and separating various components from flaxseed meal based on a subcritical composite solvent, including the following steps: adding an extraction agent to flaxseed meal for subcritical extraction to obtain a crude flax lignan extract and crude flaxseed oil in one step, where the extraction agent includes n-butane and anhydrous ethanol at a volume ratio of 1:1; adding n-hexane to the crude flaxseed oil for fractional extraction, and conducting rotary evaporation to obtain flaxseed oil; and subjecting the flaxseed meal used to hot water extraction to obtain flaxseed gum. In the present disclosure, the subcritical composite solvent used in an extraction process can replace a large number of organic reagents used in a traditional extraction process, and has the characteristics of good solvent effect, environmental friendliness, recyclability, and low burden on the environment.

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).
