Lub plhaub nqus hluav taws xob ntawm lub scraper evaporator yog nruab nrog lub tsho ua kom muaj cua sov, uas yog nruab nrog lub ntsej muag tig los yog lub taub hau tawg.
Muaj ob hom scrapers: hom tsau thiab hom rotor. Qhov sib txawv nruab nrab ntawm qhov qub thiab sab hauv phab ntsa ntawm qhov rooj yog 0.5 mus rau 1.5 hli, thiab qhov sib txawv nruab nrab ntawm tom kawg thiab phab ntsa nws txawv nrog kev sib hloov ntawm rotor.
Cov khoom siv ua kua yog ntxiv rau hauv cov kev taw qhia tangential los ntawm sab qaum ntawm cov evaporator (tseem ntxiv rau cov khoom tawg uas yog coaxial nrog tus scraper).
