Qhov muab xam cov qauv ntawm qhov chaw evaporation ntawm cov dej khov cia evaporator yog tib yam li ntawm lwm cov chav txias txias. Nws tseem tuaj yeem xaiv tau raws li thaj chaw ntawm cov dej khov cia, feem ntau nrog thaj chaw evaporation ntawm 0.6 ~ 0.7m2 raws li thaj chaw ntawm ib square meter. Qhov ntsuas kub ntawm lub khw dej khov yuav tsum txiav txim siab raws li hom dej khov cia. Qhov kub ntawm lub khw dej khov rau khaws cia cov dej khov brine yuav tsum yog -4 ℃, thiab qhov kub ntawm lub khw dej khov rau khaws cov nab kuab khov yuav tsum -18 ~ -15 ℃. Thaum tsim cov kav dej ntawm lub tub yees system, nws yuav tsum txiav txim siab tias cov dej khov cia tseem tuaj yeem txias thaum cov dej khov ua tsis nyob hauv ntau lawm. Lub tswv yim lim ntawm cov qauv evaporator tuaj yeem ua tus kheej sib npaug txhuam.
Thaum txhim kho lub tshuab raj evaporator, tsis tas yuav teeb tsa cov kav dej thaiv phab ntsa rau cov dej khov nab kuab nrog lub tsev siab meej me dua 6m, tab sis cov kav dej sab saum toj yuav tsum tau tawg thiab tawg, thiab rau cov dej khov rau hauv tsev nrog qhov siab meej txog 6m lossis siab dua, cov yeeb nkab phab ntsa yuav tsis siv rau cov fins. Flake tube kom tiv thaiv cov pawg pob khov kom tsis txhob sib tsoo.
