Comparative experiment on the use of a film electric heater for drying wood in vacuum conditions

Abstract

The research was carried out at the expense of the grant of the Russian Science Foundation No. 23-76-01090, https://rscf.ru/project/23-76-01090/. The article outlines the need for woodworking enterprises to re-equip existing ones and create new technologies for deep processing. The trends of the Russian market dictate the conditions for choosing primarily domestic equipment, in this regard, the development of innovative, energy-saving, environmentally friendly wood processing technologies is relevant. Drying plants with the use of film electric heaters in vacuum conditions are a promising area of research. The proposed development will reduce the carbon footprint, with the output of high-quality lumber and reduced energy costs. The materials present the results of an experiment on the use of a film electric heater for drying wood in vacuum conditions in comparison with the traditional technology of its application. As a result, drying in vacuum conditions allowed to reduce the process by 35%, electric energy costs by 25%. The obtained result indicates the feasibility of further research in the field of low-temperature drying in vacuum conditions.
