The article deals with hydrothermal properties of grain and describes its behavior during moisture treatment, for optimization of technological properties of flour, cereals and mixed fodders, influence of humidity on storage and processing modes of grain and grain products. The moisture content of the grain is discussed, which exceeds the established norm, as a result of which the grain begins to rapidly spoil and the amount of useful substances in it sharply decreases. In this regard, it is recommended to control the processing processes of grain processing, which includes control and regulation of humidity at all stages, from raw material procurement to storage and shipment of finished products.
In order to achieve the goal, it is proposed to study, scientific justification, and to decide on specific and little learned tasks of research in the field of measurement of technological parameters of grain.
The requirements for selection of the method and design of the instrument for controlling the moisture content of the grain, as well as their high measurement accuracy, the possibility of taking measurements in a continuous technological flow, where the subject of the study should be theoretical and experimental research based on the use of high-frequency or ultra-high-frequency methods and their equipment for controlling the moisture content of the grain in technological processes, are analyzed.
Recommendations are given for the development of the nomenclature of standardized metrological characteristics of measuring instruments, and justification of the method of their experimental evaluation, as well as measures aimed at ensuring uniformity of measurements and verification schemes for the developed instruments and control methods for enrichment products, as well as requirements for metrological characteristics of grain moisture control instruments.

Don tarkibidagi namlik muhokama qilinadi, bu belgilangan me'yordan oshib ketadi, buning natijasida don tezda yomonlasha boshlaydi va undagi ozuqaviy moddalar miqdori keskin kamayadi. Shu munosabat bilan, donni qayta ishlashning texnologik jarayonlarini, xomashyoni sotib olishdan tortib, tayyor mahsulotni saqlash va jo‘natishgacha bo‘lgan barcha bosqichlardagi namlikni nazorat qilish va tartibga solishni o‘z ichiga olgan nazoratni amalga oshirish tavsiya etiladi.
Maqsadga erishish uchun donning texnologik parametrlarini o‘lchash sohasidagi aniq va kam o‘rganilgan tadqiqot muammolarini o‘rganish, ilmiy asoslash va qarorlarni qabul qilishni taklif etiladi.
Donning namligini nazorat qilish uchun asboblarni tanlash usulini va dizaynini tanlash talablari, shuningdek ularning yuqori aniqligi, uzluksiz jarayon oqimi sharoitida o‘lchash imkoniyati, bu erda ishning mavzusi yuqori chastotali yoki mikroto‘lqinli chastotalar va ularning jihozlaridan foydalanishga asoslangan nazariy va eksperimental tadqiqotlar o‘tkazish va texnologik jarayonlarda donning namligini nazorat qilish uchun mo‘ljallangan.
O‘lchov vositalarining standartlashtirilgan metrologik tavsiflari nomenklaturasini ishlab chiqish va ularni eksperimental baholash metodologiyasini asoslash, shuningdek ishlab chiqilgan asboblar va boyitishni nazorat qilish usullari bo‘yicha o‘lchovlar va kalibrlash sxemalarini bir xilligini ta'minlashga qaratilgan chora-tadbirlar, shuningdek donning namligini boshqarish moslamalarining metrologik xususiyatlariga qo‘yiladigan talablar keltirilgan.

В статье рассматриваются гидротермические свойства зерна и описываeтся его поведение при влаготепловой обработке для оптимизации технологических свойств муки, крупы и комбикормов, влияние влажности на режимы хранения и переработки зерна и зернопродуктов. Обсуждается содержание влаги в зерне, превышающее установленную норму Влажное зерно начинает быстро портиться, а количество полезных веществ в нем резко уменьшается. В связи с этим рекомендуется производить управление технологическими процессами переработки зерна, предусматривающее контроль и регулирование влажности на всех этапах, начиная с заготовки сырья, до складирования и отгрузки готовой продукции.
Для достижения цели предлагается изучение, научное обоснование, и принятие решений по конкретным и малоизученным задачам исследования в области измерения технологических параметров зерна.
Проанализированы предъявляемые требования к выборам метода и проектирования приборного обеспечения контроля влажности зерна, а также его высокой точности измерения, возможность проведения измерений в непрерывном технологическом потоке, где предметом исследования должно являться проведение теоретических и экспериментальных исследований, основанных на использовании высокочастотных или сверхвысокочастотных методов и их аппаратурного обеспечения, предназначенных для контроля влажности зерна в технологических процессах.
Даны рекомендации по разработке номенклатуры нормируемых метрологических характеристик измерительных приборов, и обоснование методики их экспериментальной оценки, а также мероприятий, направленных на обеспечение единства измерений и создание поверочных схем для разрабатываемых приборов и методов контроля продуктов обогащения, а также требований к метрологическим характеристикам приборов контроля влажности зерна.
