Isikhwama Esibuyisela Ukupakisha Ngokwezifiso ukuze uthole ukudla osekulungele ukudliwa. Amapokhethi Abikayo amaphakheji avumelana nezimo afanele ukudla obekudinga ukushiselwa ekushiseni okushisayo okufika ku-120℃ kuya ku-130℃ futhi ahlanganise izinzuzo zamathini ensimbi namabhodlela. Njengoba ukupakishwa kwe-retort kwenziwa ngezingqimba eziningana zezinto, ngayinye inikeza izinga elihle lokuvikela, inikeza izakhiwo zokuvinjelwa okuphezulu, impilo yeshalofu ende, ukuqina kanye nokumelana nokubhoboza. Isetshenziselwa ukupakisha imikhiqizo ene-asidi ephansi njengenhlanzi, inyama, imifino kanye nemikhiqizo yerayisi.Izikhwama ze-Aluminium retort zenzelwe ukupheka okusheshayo okusheshayo, njengesobho, isobho, izitsha zepasta.
