Ochiq quyoshda qishloq xo‘jaligi mahsulotlarini quritish an’anaviy quritish usullaridan biri hisoblanadi. Quyosh energiyasidan foydalangan holda, oziq-ovqat mahsulotlarini quritish uchun ko‘pincha turli o‘lcham va modellarga ega quritgichlar qo‘llaniladi. Majburiy konveksiyali quyosh quritgichi o‘rik mahsulotini quritishga doir so‘nggi ishlanmalardan biri bo‘lib, uning ishlash samaradorligini oshirish bo‘yicha hisoblashlar yetarlicha ko‘rib chiqilmagan. Ushbu ishda majburiy konveksiyali quyosh quritgichida o‘rikdan yuqori sifatli turshak, bargak (qaysa) va kuraga tayyorlash jarayoni tahlil etildi. Shuningdek, quritish vaqtining havo sarfi va haroratiga bog‘liqlik xususiyatlari ko‘rib chiqildi. Nazariy hisoblashlar natijalariga ko‘ra, havo sarfi 0,018, 0,028 va 0,034 kg/s bo‘lgan qiymatlarda quritish vaqtlari hisoblandi. Massasi 4 kg ho‘l o‘rikdan 48,36 daqiqada 750 g quritilgan o‘rik olish nazariy tadqiq qilindi. Majburiy konveksiyali quyosh quritgichida berilayotgan havo sarfi va haroratining o‘zgarishi quritish vaqtiga ta’sir qiluvchi asosiy parametrlari ekanligi aniqlandi.

Сушка сельскохозяйственной продукции на открытом солнце – один из традиционных способов сушки. Сушилки различных размеров и моделей часто используются для сушки пищевых продуктов с использованием солнечной энергии. Солнечная сушилка с принудительной конвекцией является одной из новейших разработок в области сушки абрикосовой продукции, и анализ расчётов повышения её производительности ещё недостаточно рассмотрен. В данной работе проанализирован процесс приготовления высококачественных туршака, баргака (кайсы) и кураги из абрикосов в солнечной сушилке с принудительной конвекцией. Также были учтены характеристики воздушного потока и зависимость температуры от времени сушки. По результатам теоретических расчётов определено время сушки при значениях расхода воздуха 0,018, 0,028 и 0,034 кг/с. Теоретически из 4 кг влажных абрикосов можно получить 750 г кураги за 48,36 минут. Установлено, что поток воздуха и изменение температуры в солнечной сушилке с принудительной конвекцией являются основными параметрами, влияющими на время сушки.
Drying of agricultural produce in the open sun is one of the traditional methods of drying. Dryers of various sizes and models are often used to dry food produce using the solar energy. The forced convection solar dryer is one of the recent developments in drying of apricots, and calculating its performance improvement is not sufficiently studied. This work reviews the process of making of high-quality turshak, bargak (qaysa) and kuraga from apricots using the forced convection solar dryer. Also, characteristics of air flows and temperature dependence on drying time have been taken into consideration. According to findings from theoretical calculations, drying time has been calculated at the air flow values of 0.018, 0.028, and 0.034 kg/s. Theoretically, 750 g of dried apricots can be obtained from 4 kg of wet apricots in 48.36 minutes. It was found that the air flow and temperature changes in the forced convection solar dryer are the main parameters affecting the time of drying.
