The problem of reducing the drying time maintaining the quality of the sawn timber is up to date. For drying timber along with convective apply special methods, where drying takes place much faster. The most difficult is the drying of hardwood lumber. This requires a lot of time for drying, and the quality of dry lumber is significantly reduced. This article discusses the analysis of oak lumber vacuum-pulse method, which can be attributed to a special method of drying. The technique of definition of a loss of moisture from experienced oak samples. Presents a schematic of the experimental setup, where the described equipment. Taken into account the following parameters timber: initial moisture, the mass of the samples in the original condition and weight of the samples after drying, the time the samples in the experimental setup. Results of the research revealed regularity loss of moisture from the prototypes for a relatively short period of time along with the traditional drying methods.
