Machines for washing beer kegs and like containers

Abstract

Abstract A MACHINE FOR AUTOMATICALLY WASHING BEER KEGS OR LIKE CONTAINERS COMPRISES A HEAD WHICH IS ARRANGED TO BE APPLIED TO THE BUNG HOLE OR OTHER OPENING OF THE CONTAINER AND WHICH HAS AN INLET PASSAGE FOR THE SUPPLY OF WASHING LIQUID TO THE CONTAINER AND FOR THE SUPPLY OF STEAM OR GAS UNDER PRESSURE AND AN OUTLET PASSAGE OUT OF WHICH LIQUID SUPPLIED TO THE CONTAINER IS BLOWN BY THE STEAM OR GAS, THE SUPPLY OF LIQUID AND GAS OR STEAM AND OTHER OPERATIONS OF THE MACHINE BEING CONTROLLED BY A CONTROL DEVICE. THE CONTROL DEVICE IS CONNECTED TO A LIQUID DETECTOR WHICH IS IN COMMUNICATION WITH THE OUTLET PASSAGE, SUCH THAT AFTER THE SUPPLY OF WASHING LIQUID AND THE SUBSEQUENT SUPPLY OF GAS OR STREAM, THE DETECTOR CAUSES THE CONTROL DEVICE TO INITIATE A FURTHER OPERATION OF THE MACHINE ONLY WHEN THE DETECTOR DETECTS THE ABSENCE OF WASHING LIQUID IN THE OUTLET PASSAGE. THE DETECTOR IS AN ELECTRICAL DEVICE WHICH IS SENSITIVE TO THE ELECTRICAL CONDUCTIVITY OF THE FLUID FLOWING THROUGH THE OUTLET PASSAGE, THE CONDUCTIVITY OF LIQUID BEING GREATER THAN THE CONDUCTIVITY OF STEAM OR GAS.
