<p>A process for drying wood at subatmospheric pressures comprising a phase in which the wood is heated up in a sealed environment, is characterised in the fact that this heating-up phase comprises the operations of a I) - introducing into said closed environment an operative fluid which is capable of imparting moisture to the wood, causing this fluid to cycle repeatedly around a closed circuit in such a way that in every cyole, the fluid passes through a pile formed by the pieces of wood 9 and then returns without passing through the pile; II) - supplying thermal energy to the operative fluid in such a way that the thermal content of the fluid increase overall in each cycle at a diminishing rate until the fluid reaches a substantially steady cyclical state in which there is no overall increase in its thermal content in each subsequent cycle.</p> |
