Isingxobo sokuBuyiselwa sokupakisha esilungiselelwe ukutya esilungele ukutyiwa. Iipowutshi ezixelwayo zipakishwe bhetyebhetye zilungele ukutya obekufuneka kufudunyezwe kwiqondo lobushushu bokuqhuba i-thermal ukuya kuthi ga kwi-120℃ ukuya kwi-130℃ kwaye idibanise iingenelo zeetoti zentsimbi kunye neebhotile. Njengoko ukupakishwa kwe-retort kwenziwa ngamaleko aliqela ezinto, nganye inika umgangatho olungileyo wokhuseleko, ibonelela ngeempawu zesithintelo esiphakamileyo, ixesha elide leshelufu, ukuqina kunye nokumelana nokubhoboza. Isetyenziselwa ukupakisha iimveliso zeasidi ephantsi njengentlanzi, inyama, imifuno kunye nemveliso yerayisi. Iipowutshi ze-aluminium zokubuyiswa zenzelwe ukupheka okukhawulezayo okukhawulezayo, okufana nesuphu, isosi, izitya zepasta.
