DEGRADATION DETECTING DEVICE FOR EDIBLE OIL AND FAT AND FRIER HAVING THE SAME DEVICE

摘要

PURPOSE: To detect simply a degradation degree of edible oil and fat. ;CONSTITUTION: A cylindrical cell 21 storing edible oil and fat and having a quartz window 21a is housed in a box body 10 from which light from outside is intercepted. An ultraviolet radiation emitting element 24 such as having the peak of radiation emitting intensity in an ultraviolet radiation area is arranged on one side while interposing the cell 21 between it and the other side, and an ultraviolet radiation receiving element 25 is arranged on the other side. A degradation degree of edible oil and fat is detected according to a radiation receiving quantity of the ultraviolet radiation receiving element 25 by using a phenomenon that degradation of the edible oil and fat is related largely to absorptivity of ultraviolet radiation, and that effect is informed by an electric circuit 30. Since the edible oil and fat in an oil tank of a frier is made to be introduced automatically to the cell 21, the degradation of the edible oil and fat in the oil tank can be detected while cooking a food.;COPYRIGHT: (C)1994,JPO&Japio
