Czech Republic | Messer has installed Clapet nozzles on a new mixer cooling system used by the meat processor Maso Jičín at its Roudnice nad Labem site. These nozzles feed cryogenic gas into the mixer from the bottom. In this case, liquid nitrogen is used to process fresh ground meat. The nozzles are designed to meter the precise quantity of gas needed to achieve the desired product temperature. They are operated by the gas pressure and need no heating, so they consume no additional energy. The hygienic design of the nozzles prevents residual product or cleaning fluid from entering the gas line.
