Abstract

Convective drying is the most common method of drying lumber and blanks, veneer and chipped wood, shaped pieces and other wood products. The main equipment for drying veneer are roller dryers. For drying the chipped wood that is used for manufacturing particleboards, powerful drum dryers are mostly used where the drying agent is flue gases generated from the combustion of a mixture of natural gas and sander dust. The use of independent sources of thermal energy in the processes of drying veneer and chipped wood waste is an urgent problem, the solution of which allows recycling a variety of waste wood in woodworking industry, furniture making, sawmilling, plywood manufacturing and other industries, and also used wood which has exhausted its service life (post consumer wood). The received results of theoretical and experimental studies are recommended for use in woodworking and other industries that produce rotary-cut veneer and chipped wood, and enterprises that manufacture products from rotary-cut veneer (plywood, furniture items, musical instrument ,etc.) and also plants that manufacture products from chipped wood (particleboards, fuel briquettes and pellets and other products).
