Madzi oundana ali ndi ubwino wodziwikiratu poyerekeza ndi mitundu yakale ya njerwa za ayezi (ayizi wamkulu) ndi ayezi wa chipale chofewa.Ndilouma, losavuta kuphatikizira, lili ndi madzi abwino, ukhondo wabwino, malo akuluakulu okhudzana ndi zinthu zosungirako zatsopano, ndipo sizovuta kuwononga zinthu zosungira mwatsopano.Ndi mankhwala omwe amalowa m'malo mwa mitundu ina ya ayezi m'mafakitale ambiri.Ubwino wake ndi:
A. Kuchita bwino kwambiri popanga ayezi komanso kuzizira pang'ono: makina opangira ayezi odziwikiratu amatengera mpweya wozungulira wa mpeni wodulira madzi oundana.Popanga ayezi, chipangizo chogawa madzi mkati mwa chidebe cha ayezi chimawaza madziwo mofanana mu chidebe cha ayezi.Khoma lamkati limaundana mwachangu, ndipo madzi oundana akapangidwa, amadulidwa ndikugwetsedwa ndi mpeni wa ayezi wozungulira, kotero kuti pamwamba pa evaporator imagwiritsidwa ntchito mokwanira komanso mphamvu ya opangira ayezi imawongoleredwa.
B. Ubwino wabwino, wowuma komanso wosagwirizanitsa: Kuchuluka kwa ayezi wa flake opangidwa ndi evaporator ofukula ya makina oundana oundana ndi 1-2 mm, ndipo madzi oundana owuma osakhazikika amakhala ndi madzi abwino.
C. Mapangidwe osavuta komanso ang'onoang'ono.
Makina oundana a ayezi amaphatikizapo mtundu wa madzi abwino, mtundu wa madzi a m'nyanja, gwero lozizira lodzisunga, gwero lozizira loperekedwa ndi ogwiritsa ntchito, kusungirako ayezi ndi mndandanda wina.Kuchuluka kwa ayezi tsiku lililonse kumayambira 500Kg/24h mpaka 60tons/24h ndi zina.Ogwiritsa ntchito amatha kusankha chitsanzo choyenera malinga ndi nthawi yogwiritsira ntchito komanso mtundu wamadzi.Poyerekeza ndi makina a ayezi achikhalidwe, ali ndi malo ochepa komanso otsika mtengo (palibe munthu wapadera yemwe amafunikira kuchotsa ayezi ndi kutenga ayezi).
Makhalidwe a flake ice:
A. Direct kutentha otsika, otsika ayezi kutentha, akhoza kufika pansi -8 °.
B. Madzi oundana ndi owuma komanso oyera, okongola mawonekedwe, osavuta kupanga chipika, chabwino mumadzimadzi, aukhondo komanso osavuta.
C. Kapangidwe kameneka, kotero kuti malo okhudzana ndi firiji ndi aakulu, ndipo zotsatira zoziziritsa zimakhala zabwino kwambiri.
D. Flake ice alibe m'mphepete lakuthwa ndi ngodya, sichidzawononga pamwamba pa zinthu zafriji, ndipo ndi yabwino kwambiri kusungirako ndi kuyendetsa.
E. Makulidwe a ayezi amatha kufika 1mm-2mm, ndipo palibe chifukwa chophwanya ayezi, ndipo angagwiritsidwe ntchito nthawi iliyonse.
