Spectral analysis of various types of wood as the basis of low-temperature drying technology 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 characteristics of various types of wood (oak, aspen, pine) were obtained in the laboratory on the basis of the South Ural State Agrarian University using the infrared Fourier spectrometer FSM 2201. For these rocks, the wavelengths at which the maximum absorption of radiation occurs are determined, which is consistent with the operating modes of the film electric heater. The obtained result will become the basis for further research aimed at developing and creating a prototype of an infrared vacuum drying plant and an automatic control system for regulating and investigating the process in a discharged environment.
