Title:
OIL DEGRADATION DETECTOR AND FRYER
Document Type and Number:
WIPO Patent Application WO/2005/012891
Kind Code:
A1
Abstract:
In a preferred mode, an oil degradation detector or a fryer detects all the time the amount of polar compound contained in a cooking oil. A conversion table associates the oil temperature and the electrical characteristic with the polar compound. A processing section determines the corresponding polar compound amount according to the measured oil temperature and electrical characteristic by referencing to the conversion table. A display control section outputs the obtained polar compound amount. Thus, a polar compound amount can be outputted by referencing to the conversion table in terms of the measured oil temperature and the electrical characteristic, even during cooking.
