The article describes the simulation of the temperature field in a wide range of structural and operational parameters of the drying process. A qualitatively new representation of the temperature field profile in the chamber is revealed. As a result of the experiments, criteria were found for the unevenness of the temperature profiles on the pallets of the dispersion of the temperature of the material and the slope of the approximating line at fixed values of the average temperature of the substance. In the course of the work, an interrelation between the criteria of unevenness was revealed, which is clearly manifested when comparing optimization options according to various criteria. The solution to the optimization problem gives small deviations. The developed model allows you to organize process control taking into account strategic tasks: maximum performance or minimum power consumption. An engineering technique is proposed for selecting individual operational and design parameters of the installation based on the proposed nomograms.
Maqolada quritish jarayonining konstruksiya va rejimli parametrlarining harorat maydonini variantli keng diapozonlari modeli yaratilganligi keltirilgan. Kamerada harorat maydoni profillarining yangi sifatli tasviri aniqlangan. Har bir tagliklardagi substanstiyaning fiksastiyalangan qiymatlarning o‘rtacha haroratida to‘g‘ri aproksimastiyalanadigan burchak qiyaligi va materialning harorat dispersiyasi harorat profilini notekis mezonlari olib borilgan tadqiqotlar natijasida aniqlangan. Ishni olib borish jarayonida turli mezonlar bo‘yicha variantlar optimizastiyasi taqqoslanganda ko‘rinib turgan notekisliklar mezoni o‘rtasidagi bog‘liqlik aniqlandi. Optimallashtirish vazifaning yechimi kichik aksariyatni olib keladi. Ishlab chiqilgan model strategik vazifalarni inobatga olgan jarayonni boshqarishni tashkil etish imkonini beradi.

В статье описано осуществление моделирования температурного поля в широком диапазоне варьирования конструктивных и режимных параметров процесса сушки. Выявлено качественно новое представление профиля температурного поля в камере. В результате проведённых экспериментов были найдены критерии неравномерности профилей температуры по поддонам дисперсии температуры материала и угла наклона аппроксимирующей прямой при фиксированных значениях средней температуры субстанции. При выполнении работы была выявлена взаимосвязь между критериями неравномерности, которая наглядно проявляется при сравнении вариантов оптимизации по различным критериям. Решение оптимизационной задачи обеспечивает незначительные отклонения. Разработанная модель позволяет организовать управление процессом с учётом стратегических задач: максимальная производительность или минимальная энергоёмкость. Предложена инженерная методика выбора отдельных режимных и конструктивных параметров установки на основе предложенных номограмм.
