PURPOSE:To inject raw liquid into a separate container efficiently at a required accuracy by automatically using discharge nozzles of a large and small diameter provided on row liquid tanks according to the required quantity of injection and allowable error in quantity of injection. CONSTITUTION:Raw liquid tanks 1 separately storing raw liquids A, B, C... are each equipped with a liquid feed tube 4 for delivery of raw liquid at the bottom thereof and the pressure in the tanks is linked to an air header 5 to be adjusted with a pressure adjustor 7. The liquid feed tube 4 of each raw liquid tank 1 is provided with two discharge valve 8-1 and 8-2 and the tip of each thereof is provided with discharge nozzles 9-1 and 9-2 different in the diameter. A controller controls the adjustor 7 and the opening or closing of electromagnetic valves 10-1 and 10-2 to obtain a specified injection level of the raw liquid 1 based on setting conditions, operational conditions and a signals inputted from detectors whereby a lift and a conveying device are regulated with an electromagnetic valve 14 when the injection and blending of various raw liquids is completed. |
