Abstract: Сущность изобретения: субстанцию, подлежащую обработке, имеющую консистенцию текучей среды, непрерывно наносят в виде тонкого слоя на верхнюю поверхность теплообменной стенки. Эту стенку нагревают до температуры, которая достаточна для того, чтобы заставить быстро испаряться воду и/или другие летучие компоненты, содержащиеся в субстанции. Сухие твердые остатки удаляются по мере их образования на верхней поверхности посредством скобления боковой поверхности. Теплообменную стенку нагревают посредством пара, который получают в результате испарения. Упомянутый пар механически сжимают и затем приводят в соприкосновение с нижней поверхностью теплообменной стенки с тем, чтобы конденсировать по ней. При этом жидкий конденсат впоследствии удаляют. Этот способ извлечения является особенно дешевым вследствие того, что энергия, выделяемая при конденсации, используется на другой стороне теплообменной стенки при испарении. Могут быть высушены и другие субстанции, в частности шлам свиноферм. 2 с. и 16 з.п.ф-лы, 10 ил.
