• Vula i-evaporation-Inqubo lapho ikhofi ingabilisa khona ekushiseni okuphansi. Ibuye isetshenziselwe ukwenza i-ketchup, ubisi oluyimpuphu kanye nokunye ukudla kokuhweba.
• Gwema Ukugxila-Inqubo eningi yokunambitheka enhle lapho iqhwa elisekelwe ngamanzi lisuswe, lashiya uketshezi oluthe xaxa ngemuva. Ibuye isetshenziselwe ukwenza ama-juice esithelo, i-applejack, nama-vinegars agxile kakhulu.

1. Ikhofi noma ingqikithi yekhofi (eyenziwe ukugxila kwefrijini) ngokushesha iqhwa kuya nxazonke -40 F (futhi, -40 Celsius).

1. Ifakwe ekamelweni lokumisa, i-vacuum yenziwa ekamelweni bese ikamelo livutha.
2. Njengoba ikhofi efriziwe ivuseleleka, amanzi afriziwe asheshe agcwalise igesi kwinqubo ebizwa ngokuthi i-sublimation. Okushiywe yizinhlamvu ezomile zekhofi.

Indlela Yokusula-Ukumisa

Indlela yokwafafaza okwenza ikhofi esheshayo cishe nje ngokuphuza ikhofi. Ukushintshwa kwekhofi eliketshezi kuya ikhofi esheshayo kuthatha amasekhondi angu-5 kuya kwangu-30 kuphela.

2. Njengoba amaconsi awela, amanzi asele aphuphuma.
3. Amakhekhe efihlekile wekhofi awela phansi ekamelweni.

Ngeshwa, kule nqubo, amazinga okushisa aphezulu athambekele ekuthinteni amafutha wekhofi futhi ngaphezulu kwelavata ilahlekile. Futhi, ngokuvamile iveza kahle kakhulu i-powder. Ukuze wenze i-powder iyamukeleke kubathengi, okusanhlamvu kufakwa kanye nokucubungula okwengeziwe okubandakanya umusi.
