Conventionally, this type of cooking oil heating device has (a)
As shown in Figure 2 A, a pot 1 containing cooking oil a
3 and a combustion device 14 that heats the pot 13, or (b) As shown in FIG. A once-through type is known in which a heating coil 17 for heat exchange is provided and the cooking oil a is pumped to the heating coil 17 by a pump 18 to heat the cooking oil a.
しかし、前記の従来装置のうち、前者(イ)の食用

伝達率が低いため、熱効率が30％程度と低いこと
はもちろん、食用油と鍋とが接する境膜温度が一
般的な食用油の劣化温度（約200℃）以上となり
易く、食用油の劣化を早める欠点があつた。
However, among the conventional devices mentioned above, when using the cooking oil heating device in the former (a), it is a direct fire type that heats the cooking oil in the pot using natural convection, and the heat transfer rate from the pot to the cooking oil is low. As a result, the thermal efficiency is low at about 30%, and the temperature of the film where the cooking oil and the pan come into contact tends to exceed the deterioration temperature of general cooking oil (approximately 200℃), which has the disadvantage of accelerating the deterioration of the cooking oil. It was hot.

In order to increase the temperature (flame temperature), the flame temperature is
The temperature is far above 200℃. the result,
Due to incorrect operation, the flow rate of the cooking oil flowing inside the heating pipe may decrease or the flow of cooking oil may stop, or the heating pipe may become partially damaged due to uneven combustion flame due to improper installation of the combustion equipment. If the cooking oil is overheated, as in the former case (a), the film temperature will exceed the deterioration temperature of the edible oil, promoting deterioration of the edible oil. In particular, if it is excessive, it can lead to the worst situations such as high-temperature carbonization of the edible oil and damage to the heating coil.
