Abstract
The invention provides a method of deep frying coated ingredients, while giving high-frequency AC energy to frying oil or spraying water decreased in ORP value, method of suppressing degradation of the frying oil, an apparatus for giving high-frequency AC energy to the frying oil in a deep fryer, and a deep fryer which incorporates the apparatus for giving high-frequency AC energy to the frying oil. The supply of high-frequency AC energy or spraying the water decreased in ORP value suppresses an increase of acid value in the frying oil, which depends on heating period of time, and spattering of oil and/or water drops, which occurs, when the coated ingredients are dropped into the heated frying edible oil.
Claims10
A method of deep frying coated ingredients, which comprises the steps of:
- arranging a pair of applying electrodes and a grounding electrode in frying edible oil accommodated in a deep fryer;
- supplying high-frequency AC voltage to the applying electrodes;
- heating the frying edible oil to a predetermined temperature;
- and
- deep frying the coated ingredients.
A method of deep frying coated ingredients, which comprises the steps of:
- providing a pair of applying electrodes and a grounding electrode in frying edible oil accommodated in a deep fryer;
- connecting first and second switches respectively to a DC voltage source through a variable resistor;
- connecting a switching commander circuit which is a flip-flop circuit to the switches through a resistor;
- connecting an oscillator to the switching commander circuit:
- alternately outputting a switching command by the switching commander circuit to the first and second switches, so that the first and second switches are periodically turned ON and OFF:
- alternately applying voltage to the pair of applying electrodes;
- heating the frying edible oil to a predetermined temperature;
- and
- deep frying the coated ingredients.
