    • When the start button is pushed after the door of the supply chamber is closed, carbon dioxide gas is ejected from the nozzle placed at the upper part of the horn. The carbon dioxide gas is converted to powdered dry ice by adiabatic expansion in the horn, and the dry ice falls on fresh food or other items to be cooled in a box or plastic bag placed under the horn. In order to obtain a desired amount of dry ice constantly, the ambient temperature, the pressure of the carbon dioxide gas, the interval time since the last ejection are counted in determining the carbon dioxide ejecting time length.
    • 当在供应室的门关闭之后按下启动按钮时,二氧化碳气体从位于喇叭上部的喷嘴喷出。 将二氧化碳气体通过喇叭中的绝热膨胀转化为粉末状干冰,并将干冰落在新鲜食品或其它待冷却的物品中,该箱子或塑料袋放置在喇叭下方。 为了恒定地获得所需量的干冰,在确定二氧化碳喷射时间长度时,计数环境温度,二氧化碳气体的压力,自上次喷射以来的间隔时间。
