A scraped surface heat exchanger (SSHE) imhando ye heat exchanger iyo inoshandiswa kupisa kana kutonhodza zvinwiwa zvine viscous zvakanyanya kana zvinonamira zvisinga gadziriswe zvine mutsindo mumagetsi echinyakare. Iyo SSHE ine cylindrical shell ine inotenderera yepakati shaft ine akawanda scraper blades akabatanidzwa pairi.
Iyo yakanyanya viscous fluid inopinzwa muhumburumbira uye inotenderera scraper blades inofambisa iyo mvura inoyerera mukati memadziro emukati ehumburumbira. Mvura inodziya kana kutonhodzerwa nekunze kwekupisa kwemhepo kunoyerera kuburikidza negoko reiyo exchanger. Sezvo mvura inofamba ichitevedza mukati memadziro ehumburumbira, inoramba ichikweshwa nema blades, ayo anodzivirira kuumbwa kwefouling layer panzvimbo yekutamisa kupisa uye kukurudzira kufambiswa kwekushisa kwakanaka.
Iyo yakatsvairwa yekupisa yekupisa inowanzoshandiswa muindasitiri yechikafu kugadzira zvigadzirwa zvakaita sechokoreti, chizi, kupfupisa, uchi, sosi uye margarine. Inoshandiswawo mune mamwe maindasitiri kugadzira zvigadzirwa zvakaita semapolymer, zvinonamira, uye petrochemicals. Iyo SSHE inofarirwa nekugona kwayo kubata zvakanyanya viscous zvinwiwa zvine kusvibiswa kushoma, zvichikonzera kushanda kwepamusoro uye nguva refu yekushanda pane yechinyakare kupisa kupisa.
