A number of experimental studies were conducted on seeds of agricultural plants and of their grindings in order to adapt the photoluminescent method for controlling the bulk food products quality indicators. The spectra were measured according to a technique previously developed by the authors. The spectral characteristics of excitation and of the luminescence of products of different humidity are qualitatively similar, but with increasing humidity, the curves shift down. The excitation and luminescence spectra of grindings shift down with an increase in the average diameter of grinding particles. The developed technologies for photoluminescent control include sample preparation, luminescence excitation at a wavelength of 424 nm, its registration in the range of 450–650 nm, and amplification of the received electrical signal. Further, based on the previously established dependencies, humidity indicators or average particle diameters are determined, after which a decision is made as further actions to be conducted with the products.

通过光致发光方法控制散装产品的湿度和研磨尺寸光致发光质量控制

为了适应用于控制散装食品质量指标的光致发光方法，对农业植物的种子及其粉碎物进行了许多实验研究。光谱是根据作者先前开发的技术测量的。不同湿度产品的激发光谱和发光光谱特征在质量上相似，但是随着湿度的增加，曲线向下移动。磨料的激发和发光光谱随磨料颗粒平均直径的增加而下降。用于光致发光控制的已开发技术包括样品制备，在424 nm波长处的发光激发，其在450–650 nm范围内的配准以及对接收到的电信号的放大。进一步，
