Development of a method for luminescent control of moisture content in corn and wheat grindings in feed preparation

The results of the study of the optical properties of corn and wheat grain grinds at different moisture content are presented in the studied samples. A technique for varying the moisture content in grain grinds with optical measurements to determine correlation and spectral dependencies is proposed. A diffraction spectrofluorimeter CM2203 (Solar CJSC, Belarus) was used for optical spectral measurements. Measurements of the spectral characteristics of excitation n(λ) with extended scanning in synchronous mode were carried out in the range from 230–600 nm, with an average sensitivity of a photoelectron multiplier, pulse duration tdl = 20 microseconds, pulse delay t = 0.75 microseconds. Synchronous excitation spectra of corn grain grinding with varying moisture content, photoluminescence spectra of corn grinding for λ = 362 nm with varying moisture content, photoluminescence spectra of wheat grinding with varying moisture content for λ = 362 nm were measured. The dependences of the photoluminescence flux with varying moisture content of grain grinds and their linear approximations for corn (λ = 362 nm), for wheat (λ = 362 nm) and (λ = 424 nm) are determined. Statistically reliable dependences on humidity can be obtained for integral photoluminescence fluxes when excited by 362 nm radiation for corn grinds and 362 nm and 424 nm for wheat grinds.
