Great to always get the most suitable temperature between ~ 180 ° C
Is a factor. However, as in the configuration shown in FIG.
Method, the oil temperature and the pan bottom temperature are
There is a large difference and the target temperature can be obtained depending on the amount of oil.
The fact is that it is not. That is, the pan bottom temperature and the oil temperature
Differs depending on the material, thickness and amount of oil in the pot.
It is an important condition that the temperature is adjusted to the target temperature.   FIG. 12 and FIG. 13 show specific means for implementing the method.

have.   In Fig. 12, the horizontal axis represents the time elapsed since ignition, and the vertical axis represents
Show the thermal power state, pan bottom temperature and oil temperature, respectively.
I have. Oil temperature is t as shown by the above-mentioned pan bottom temperature curve._Five℃
To make the pan bottom temperature higher than that by αdeg_FiveSet to ° C
Need to be This temperature difference αdeg is, for example, aluminum pan thickness
In the case of 4 liters of oil and 1 liter of oil, it becomes about 40deg. Ie oil
If the temperature is 180 ° C, the pan bottom temperature (pan bottom touch temperature
The set temperature of the sensor 49) must be adjusted to 220 °. or
If the iron pan thickness is 1.2 mm and the oil volume is 1 liter, set the oil temperature to 180
Is it good to match with 182 ° if it is an experimental result?
It is clear.   Both bottom temperature and oil temperature are t₀° When ignited at temperature, A₁Seconds passed
Then the pan bottom temperature is t₁°, oil temperature is 0₁° and temperature difference, Δ
t₁Occurs. Also A₁Seconds to A_TwoPan bottom temperature car in seconds
Is bent, but this tendency is
Put it out in a thick pot. This generation mechanism is based on oil heat transfer.
The conductivity is about 1/3 of water and the specific heat is about 2 times.
That is, the temperature rise curve of the pot bottom differs from the heating state of the water
Appears as   That is, if a thick pot made of a material with good thermal conductivity is used,
The heat that heats the pot makes the bottom of the pot more uniform than the oil initially transmits to the oil
The greater the heat consumed, the greater the temperature
Difference Δt₁Will appear greatly. In addition, pan bottom temperature car
The bend is not raised linearly but is caused by condensation.
And usually occurs around 70 ° C. On the other hand, heat conduction is thin
In a pot (for example, stainless steel 0.5mm), the temperature at the center of the pot bottom is oil
Less from the pot than through the oil temperature
Many are consumed in ascent. Therefore, the temperature difference Δt₁Is small
Become. From the above, until the pot bottom temperature curve bends
Temperature rise, ie t₁−t₀Is the first pot type
As a coefficient representing the material thickness, the first pot type determining means 72
Is set by A_TwoPot bottom temperature t_Two° also the oil temperature
O_TwoThere is a big difference. (T_Two−t₀), (T_Two−t₁) Is also second
Set as the next pot type determination coefficient in the second pot type determination means 73
It is. Then the pot temperature is t_Three, T_Four° and rise, but the pot bottom temperature
Degree t_ThreeOil temperature O at the time_ThreeAnd then Aα seconds have passed
Pan bottom temperature t_Four°, oil temperature O_FourBetween and t_Four−t_Three= Δ
t_Two, O_Four−O_Three= Δt_TwoThat is, the temperature rise per unit time
Will be the same. In other words, the pot bottom temperature curve and the oil temperature curve
Temperature range where the temperature rises in parallel is determined regardless of the pot and oil volume
It was found to occur in the temperature range of oil. t_Four−t_ThreeIs the oil temperature
It is the same as the temperature rise, and if the calorie burned is constant, t_Four
−t_ThreeTemperature difference has a correlation with the amount of oil, as an oil amount coefficient,
It is set by the oil amount determining means 74. Total temperature difference determination means
75 is a coefficient set by the primary pan type determining means 72,
Coefficient and oil amount judgment set by second pan type judgment means
