Abstract: today one of the main challenges facing the complex enterprises is to reduce the time ofprocessing of raw materials, reducing the costs of electricity and labor, improving the quality of the final product, improvement of technological processes of drying. A study of the development of helium dryer and intensification of the process of drying works with the help of solar energy through the use of heat storage medium. Based on the goal in the calculations helio dryer settings, prepared drawings for installation of spare parts that create infrared rays using coolant, based on the results selected the best option dryer and prepared terms of reference for the development of the device.
Keywords: helio drying equipment, accumulation, drying, process, medicinal herbs.
ЗАДАЧИ ПО АККУМУЛЯЦИИ СОЛНЕЧНОЙ ЭНЕРГИИ И ЕЕ ОТДАЧЕ
В ГЕЛИОПРИЕМНИКАХ Сафаров Ж.Э.1, Дадаев Г.Т.2 (Республика Узбекистан)
'Сафаров Жасур Эсиргапович - доктор технических наук; 2Дадаев Гани Тошходжаевич - старший преподаватель, кафедра техники сельского хозяйства, факультет машиностроительных технологий, Ташкентский государственный технический университет, г. Ташкент, Республика Узбекистан
Аннотация: сегодня одними из основных задач, стоящих перед предприятиями комплекса, являются сокращение времени переработки сырья, уменьшение расходов электроэнергии и труда, повышение качества конечной продукции, усовершенствование технологических процессов сушки. Изучение развития гелиосушилки и интенсификации процесса сушки осуществляется с помощью солнечной энергии за счет использования среды аккумулированного тепла. На основании расчётов данной гелиосушильной установки были подготовлены чертежи запасных частей для установки, которые создают инфракрасное излучение с использованием охлаждающей жидкости, на основе результатов отбирается оптимальный вариант установки - как гелиосушилка и подготовленное к ней техническое задание для её разработки.
Ключевые слова: гелиосушильное оборудование, аккумуляция, сушка, процесс, лекарственные травы.
Among the many ways to treat people, perhaps the most pleasant and natural, and to the same and one of the oldest - a herbal treatment.
Herbs can not only cure, but also to maintain our body in good tone, to increase efficiency, free up resources that spent our body to fight to improve the quality of life disease.
On the basis of solar energy currently used helio technical devices in sectors of the economy (different types of solar greenhouses, greenhouses, desalination, water heaters, dryers).

One of the most important and difficult challenges facing the food and pharmaceutical industry consists of the full provision of the population with quality food. Today one of the main challenges facing complex enterprises is to reduce the time of processing of raw materials, reducing the costs of electricity and labor, improving the quality of the final product, improvement of technological processes of drying [1 - 2].
As a result, on the basis of the research, a scheme accumulating helium medicinal herbs dryer for drying (Fig. 1). Thus, by means of analytical calculations shows the process of heating and cooling, which are linear equations of mathematical physics tasks and having known solutions. In this study, the results obtained for the medicinal herbs drying using the accumulating helium dryer border movement of a phase transition using the similarity method [3 - 4].
