PURPOSE: Solid fat pieces which are being conveyed are raised in its temperature up to the aging one by a microwave irradiator, then placed in vessels, weighted and aged by the second-stage irradiation with microwaves to shorten its aging hours.
CONSTITUTION: In the conveying stages, pieces of solid fat such as butter, margarin or hosrtening is heated up to a temperature 5°C lower than the aging temperature with the first microwave heater. The heated fat is placed in vessels and weighted and then heated up to the aging temperature by means of the second microwave heater 2. The second microwave heater 2 is equipped with the auxiliary approaching part 21, the leaked wave absorber 22, the microwave irradiation part 23 and the microwave duct connector 24. The solid fat placed in vessels are raised up in temperature to the aging one in the microwave irradiator 2, cooled by standing to finish aging.
