PURPOSE:To produce continuously a past of stable quality with good thermal efficiency, by detecting the flow rate of a raw paste material fed to a cooker and converting the detected value into the quantity of steam to be fed to the cooker. CONSTITUTION:The flow rate of an aq. soln. of a raw paste material fed from a tank 1 by means of a pump 2 is detected by a flowmeter 11 equipped with an oscillator. The detected value is input into a flow rate indication controller FIC-1 to control a frequency converter 9, whereby the number of revolutions of a motor 10 is changed to adjust it. The quantity of each of a primary diluent water and a secondary diluent water introduced through each of a primary diluent water and a secondary diluent water introduced through each of a primary diluent water passages 5 and a secondary diluent water passages 7 is detected by each of flowmeters 12, 14 equipped with an oscillator and input into each of flow rate indication controllers FIC-2, 3, and a value obtd. by converting each of signals from the flowmeters 11, 12 basing on the desired mixing ratio with ratio presetting devices Hrs-1, 2 is input as a preset value thereinto, whereby control values 6, 8 are controlled to adjust them. The flow rate of steam to be introduced into a cooker 4 is controlled by controlling a steam value 3 by correcting the signal of an operation controller XT with the signal of a temperature indication controller TIC basing on the temperature signal of a temperature sensor.
