Ama-rotary retorts asetshenziselwa ukuvula amathini noma ezinye iziqukathi ngesikhathi sokuvala inzalo nokupholisa.Inhloso ukuhambisa okuqukethwe kokudla ukuze kusheshiswe ukudluliswa kokushisa ngaphakathi kwekani, kuthuthukiswe ikhwalithi futhi kuvinjwe noma yimuphi umthelela omubi ongaba khona ohlotshaniswa nezinqubo zokushisisa okungashintshi.
Inqubo eshisayo nekhwalithi yomkhiqizo oqediwe ingathuthukiswa kakhulu kwezinye iziqukathi nemikhiqizo ngokuhambisa iziqukathi phakathi nomjikelezo wokupheka / opholile.Ukunyakaza noma ukunyakaza kweziqukathi kuphoqa ukushisa kwe-convection yomkhiqizo ngaphakathi kwesiqukathi.
Izinga lokushisa lokuvala inzalo (inani lokuvala inzalo noma i-FO) lichazwa umenzi futhi lizoncika ekungcoleni kokuqala komkhiqizo kanye nezici zawo ze-bacteriological.
