Umsebenzi wesitofu segumbi le-flash (FCC) ukunikeza isikhala sokufaka uketshezi ngokushesha kanye nokuhlukaniswa komhwamuko noketshezi. Iphuzu lokubila lento liyanda ngokucindezela okwandayo, futhi uma ingcindezi iphansi, kulapho ukubila kwehla khona. Ngale ndlela, uketshezi olunomfutho ophezulu kanye nokushisa okuphezulu lungasuswa ukuze kwehliswe iphuzu lalo lokubila bese lungena kwisitofu segumbi le-flash (FCC). Ngalesi sikhathi, izinga lokushisa loketshezi liphakeme kunephuzu lokubila ngaphansi kwalolu xinzelelo. Uketshezi luyabila ngokushesha futhi luphele ku-flash chamber cooker (FCC), futhi luhlukanise izigaba ezimbili.

U-Yinrich ungumkhiqizi wobuchwepheshe we-flash chamber cooker (FCC). Umgomo wokusebenza we-flash chamber cooker (FCC) eyenziwe yi-Yinrich ulula. Isixazululo sikashukela sihlala sifakwa kuyunithi eyakhiwe yi-heater yepayipi, igumbi lokuhlukanisa umusi, uhlelo lokuhlinzeka nge-vacuum, kanye nephampu yokukhipha amanzi. Izinto ziphekwa kusukela phansi kuya phezulu, bese zingena ekamelweni le-flash ukuze zikhiphe amanzi ku-syrup ngezinga elikhulu. Yonke inqubo ye-flash chamber cooker ye-Yinrich (FCC) yenziwa yisilawuli se-PLC.
