Title:
METHOD FOR DRYING WOOD AND AN APPARATUS FOR THE IMPLEMENTATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/098698
Kind Code:
A3
Abstract:
The invention relates to the field of wood processing. The drying method consists of the repeated alternation of the cycles of blowing air heat-carrier over the wood at atmospheric pressure while heating the wood to an average volume temperature of 80-100°C, applying a pulsed rapid vacuum with a working pressure of not more than 50 mm Hg over a time of up to 10 s with free moisture being forced out without the phase transformation of the water into vapour until a constant temperature of the wood is established, and relieving the vacuum to atmospheric pressure by supplying air heat-carrier, the wood being blown over and the vacuum relieved using air heat-carrier with a temperature of 150-300°C at an excess pressure of not more than 0.07 MPa. The apparatus for implementing this method for drying wood includes two drying chambers connected to a cooled receiver by pipes having fast-acting valves, said cooled receiver being connected in series to a second receiver and to a vacuum pump by means of a pipe with a vacuum seal. The first receiver is fitted with spiral guides for streams of vapour-droplet medium along a tangent to the inside diameter of the receiver shell. The drying chambers are connected to a heat-carrier preparation and delivery system.
