Row heating t0After time, each equal portions of food can rise different temperature values, it is consequently possible to calculate going out for each food etc.
Part, when using different combination parameter the first preset time ts of heating0Afterwards, the temperature rise value of the equal portions food, when using unit
Between temperature rise value indicate the corresponding temperature rise efficiency of the combination parameter.Specifically calculating process is：
For first combination parameter in the combination parameter set, corresponding rate of temperature change is (Tfood-w-1-T0)/
t0, for other combination parameter p (value of p is 2~i), corresponding rate of temperature change is (Tfood-w-p-Tfood-w-(p-1))/
t0, w values are 1~n.
Different location can be made actually in order to which which combination parameter known by calculating temperature rise maximum efficiency
Food obtains highest temperature rise efficiency, that highest group combination parameter of temperature rise efficiency, is that the position is corresponding
Optimum combination parameter.Using this further technical solution, rapid must obtain per the corresponding optimum combination of equal portions food can be facilitated
Parameter.
Meanwhile in this further technical solution, it is understood that there may be such situation, i.e. two or more different combinations ginsengs
Number, can make the food of same position, temperature rise efficiency having the same.In this case, in these combination parameters, no matter
Which combination parameter all can serve as the optimum combination parameter of the present invention.It in the inventive solutions, can be according to this
The sequence that a little combination parameters occur, selects the combination parameter first occurred as optimum combination parameter, such as to combination parameter set
In combination parameter, according to frequency from small to large, frequency it is identical when phase sequence from small to large be ranked up, then selection group
It closes in parameter sets, the combination parameter to sort earlier above is as optimum combination parameter.
Further, the step 4 is specially：Microwave power is set, and cycle is selected in the optimum combination parameter sets
Optimum combination parameter to the second preset time t of heat foodscook。
Advantageous effect using above-mentioned further scheme is：In this further technical solution, cycle selects the optimal set
Parameter is closed to heat food.For example the corresponding optimum combination parameter of the 1st equal portions food is selected to heat food first,
At this point, the first equal portions food has highest temperature rise efficiency, for the hot spot in the stage, other equal portions foods are also heated,
But temperature rise value is less than the temperature rise value of the first equal portions.Then the corresponding optimum combination parameter of the second equal portions food is used
Food is heated, at this point, the second equal portions food has highest temperature rise efficiency, it is the hot spot in this stage, other
Equal portions food is also heated, but temperature rise value is less than the temperature rise value of the second equal portions.The above process is recycled, until all
Optimum combination parameter work and finish.In this further technical solution, constantly changed by hot spot, and uniform fold is entirely eaten
Object improves the uniformity of heat foods process, simultaneously as the optimum combination parameter used corresponds to maximum temperature change rate, because

The microwave heating system of thermal uniformity.
Below by way of specific embodiment, the above process is illustrated.
The present embodiment uses the double source semiconductor microwave oven of beautiful group's production as microwave heating equipment, and the temperature is adopted
Collect module and uses 9 infrared temperature sensors；The present embodiment carries out microwave heating, the frequency of micro-wave oven microwave to 200g egg custards
Rate variation range is 2400~2500MHz, and the variation range of phase is 0~359 °, because as 360 ° of 0 ° of phase and phase be
's.
1) food is divided, and obtains initial food temperature.
Because 9 infrared temperature sensors can acquire the temperature of 9 points simultaneously, therefore egg custard is divided into
9 equal portions, and each equal portions are numbered from 1,2 ..., 9 respectively.
It measures the surface temperature of each equal portions respectively using 9 infrared temperature sensors, while being surveyed using the method being inserted into
The central temperature of each equal portions is measured, the surface temperature is denoted as Tsurface-j, central temperature is denoted as Tcenter-j, the value of j is 1~
