FIELD: process engineering.SUBSTANCE: invention relates to woodworking, particularly, to lumber processing. Claimed process comprises timber dressing, degassing and impregnation of blanks in sealed chamber. Impregnation solution represents a liquid phase of natural wastes of cattle. Preliminary degassing of wood blanks is performed in the chamber at 60-62 mm Hg, 70-80°C for 18-20 minutes. After chamber unsealing, impregnation solution is fed to impregnate the wood without outer pressure for 15-20 minutes.EFFECT: higher efficiency of wood protective processing.1 dwg, 2 tbl |
