Control means including rate detecting means which periodically samples the weight signal at K2 to determine the rate of {TAIL ~ change} of the sensed weight; reference means which provides a signal representing the desired rate of change of the weight; comparing means which compares the detected rate of change and the reference rate; and power control means which varies the output power of the heating means in accordance with the relationship between {HEAD ~ the detected rate} and the reference rate are provided in the form of an appropriately programmed microprocessor 106
