Maqolada paxta xomashyosini dala sharoitida yig‘ib olingandan so‘ng tozalash-ajratish korxonalariga yetkazilgunga qadar me’yoriy namligini (7–9 %) tushirish maqsadida quyosh energiyasidan foydalanuvchi gelioqurilmaning asosiy konstruktiv-texnologik parametrlarini fanlararo issiqlik-massa almashinuvi, konvektiv issiqlik uzatish nazariyasi, quritish kinetikasi va ekserginetik tahlil, uyg‘unlashtirilgan yondashuv asosida analitik asoslash masalasi ko‘rib chiqilgan. Kollektor havo yo‘lidagi konvektiv issiqlik uzatish koeffitsiyenti Reynolds–Nusselt–Prandtl mezonlari orqali, kollektorning issiqlik FIK ni esa ikkinchi tartibli Hottel–Uillier–Blis xarakteristika tenglamasi orqali aniqlangan. Quritish jarayoni Page yarim empirik modeli va Arrenius tipidagi harorat-diffuziya bog‘lanishi bilan, jarayonning termodinamik mukammalligi esa ekserginetik FIK orqali baholangan. Kollektor yuzasi va havo sarfi bo‘yicha ko‘p omilli optimallashtirish javob sirti metodikasi (RSM) asosida ikkinchi tartibli regressiya modeli yordamida amalga oshirilgan. 1000 kg/soat unumdorlikka ega qurilma uchun namlikni 10 % dan 7 % gacha tushirish sharti bo‘yicha kollektor yuzasi, havo sarfi, harorat va quritish davomiyligining raqamli qiymatlari aniqlangan hamda ularning quyosh radiatsiyasi o‘zgarishiga sezgirligi grafik-analitik tarzda tahlil qilingan. O‘zbekistonning yuqori quyosh salohiyati va paxta terimi mavsumining quyoshli oylarga to‘g‘ri kelishini hisobga olib, chiqish havosi haroratini barqarorlashtirish uchun adaptiv avtomatik boshqarish tizimini joriy etish tavsiya etilgan
