1. Khoom xaiv ntawm lub tank: Stainless hlau mixing tank yog ua los ntawm stainless hlau phaj, thiab ib tug stainless hlau phaj muaj ntau hom. Raws li lub teb chaws cov qauv, qhov tsim muaj cov tsis muaj steel hlau nws yuav tsum tau txais SUS304 stainless hlau phaj, uas feem ntau hu ua "edible grade stainless steel phaj". Cov phaj hlau no muaj cov xim qaub ncaug heev thiab cov khoom ua haujlwm siab heev. Lub tank ua los ntawm hom hlau no feem ntau muaj kev pab cuam lub neej ntev. Tshaj li 20 xyoo, thiab tuaj yeem ua tau raws li cov cai ntawm lub teb chaws haus dej haus luam yeeb.
2. Thickness xaiv ntawm phaj steel: Lub thickness ntawm ib phom steel tsis stainless yog millimeter qib. Feem ntau hais lus, nplawm tso tawm (tsawg dua 2 cubic meters) yog ua los ntawm 0.4-0.5 millimeter tuab hlau daim hlau, tab sis tsuj tsawg ntawm cov hlau phaj nrog ntau tshaj 1.0 millimeters.
