That is, the cooking process includes two half-cycles, the first half-cycle with a strong fire and the second half-cycle with a weak fire. Specifically, after entering the second state, the controller controls the heater to heat for T1 time and to heat for T2 time according to a second heating power P2 and a third heating power P3 in sequence, wherein the second heating power P2 is a first half-time average heating power, the third heating power P3 is a second half-time average heating power, P2 is greater than P3, the total time of the viscous food material processor in the second state is T, T is T1+ T2, and the heating times T1 and T2 in the two half-times may be equal or unequal. Further, the first half heating time is shorter than the second half heating time, and further, the second heating power P2 is used for heating t1 for 1 to 5 minutes, and the third heating power P3 is used for heating t2 for 10 to 30 minutes.

After the viscous food materials in the second state are boiled, the stewing process in the third state is carried out, wherein the stewing process is as follows:

the viscous food material processor stops heating and stirring the food material in the container 1, specifically, the controller controls the heater to stop heating, and simultaneously controls the motor to stop rotating the stirring paddle 2, so that the viscous food material is kept still in the container 1 for a period of time, namely, the heating and stirring of the processor are stopped, preferably, the heating and stirring stop time t3 is more than or equal to 5 minutes, after the "braising" process is finished, the processor sends out a buzzer to finish the preparation of the viscous food material, and the power of the heater is shown in fig. 10 in the processes from the second state to the fourth state. After the process of stewing, the food materials in the container 1 are cooked, and can be directly taken out for eating.

In a preferred embodiment of this embodiment, the method for processing viscous food material further comprises a fourth state of heating at a fourth power to preserve heat of the food material in the container 1. Specifically, after the stewing process is completed, the heat preservation key and the start/pause key are sequentially pressed, the processor starts to preserve heat of the viscous food materials in the container 1 according to the set temperature, and the display window displays the temperature of the food materials in real time. In the heat preservation process, when the temperature of the food materials in the container 1 is lower than 50 ℃, the controller controls the heater to heat with fourth power, when the temperature in the container 1 reaches above 60 ℃, the controller controls the heater to stop heating, and the steps are repeated, so that the food materials in the container 1 are always kept at 50-60 ℃, and the taste of the viscous food materials is kept to the maximum extent.

In the embodiment, the duration and the temperature of each time period in the processes of boiling and stewing and the rotating speed of the stirring paddle 2 can be adjusted according to the actual requirements of customers, and parameters such as time, rotating speed and the like can be preset through programming. In the processing processes of boiling and stewing, the display window displays the temperature or the remaining time of the food materials in real time or alternatively displays the temperature and the remaining time of the food materials, so that the processing process of the food materials can be visually displayed.
