ZQX-Ⅰ型餐具自动冲洗消毒机消毒效果的测定

DETERMINATION OF DISINFECTION EFFICACY OF TABLEWARE AUTOMATIC DISINFECTOR TYPE ZQX-I

ZQX-Ⅰ型自动冲洗消毒机用于餐具消毒,包括有冲洗、加热与次氯酸钠消毒3种功能。试验证明,3种功能互相协同可使餐具经40秒处理后,细菌减少到符合卫生标准。

Tableware automatic disinfector Type ZQX-I has functions of cleaning, heating and chemical disinfction and is controlled by program to make the disinfection process automatic. When the water temperature was 60～80℃, flow pressure was 0.5～1.0 kg/cm^2 and the available chlorine content of sodium hypochlorite (produced by electrolysis of NaCl) solution was higher than 100 mg/L, the spores of Bacillus cereus smeared on the tableware reduced by more than 99.9% after 40 sec treatment in the disinfector. Good result was also obtained in field trial. Disinfection by either immersion in sodium hypochlorite solution or rinse with hot water alone could not achieve similar good result.
