Description

Technical Field

[0001] The invention relates to the field of cooking control methods, and in particular to an intelligent blanching method and an intelligent cooking machine using the intelligent blanching method. Background Art

[0002] The blanching control methods of existing intelligent cooking machines are all integrated into a control stage of a specific cooking recipe, and the blanching time setting is quantitative and unchanged. When the amount of ingredients or the amount of water added by the user changes, it is difficult to ensure the blanching effect. For the blanching of meat ingredients, either the blanching time is too long, the meat becomes tough and affects the taste, or the blanching time is too short, the blood in the meat food cannot be completely removed, resulting in a heavy fishy smell, affecting the cooking taste. Ultimately, a satisfactory blanching effect cannot be achieved. Summary of the invention

[0003] The first technical problem to be solved by the present invention is to provide an intelligent blanching method that can be applied to any food and can ensure a better blanching effect in view of the above-mentioned prior art.

[0004] The second technical problem to be solved by the present invention is to provide an intelligent cooking machine with an independent blanching program for the above-mentioned prior art, and the blanching program can be applied to any food and can ensure a good blanching effect.

[0005] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: an intelligent blanching method, which is applicable to an intelligent cooking machine, characterized in that: a preset blanching time t is set, and after the intelligent cooking machine starts to execute the blanching program, the temperature of the bottom of the pot and the liquid temperature are detected in real time, and the weight of the pot and the internal food is detected in real time, and the weight loss of the pot and the internal food is obtained, and the blanching is terminated when at least two of the following three conditions are met at the same time:

[0007] Condition 2: The weight loss of the pot and the food inside is greater than the preset weight; the preset weight is 4 to 10g;

[0008] Condition 3: The actual execution time of the blanching program is greater than or equal to the preset blanching time t.

[0009] As a preferred condition, blanching is completed only when conditions 1, 2 and 3 are met at the same time.

[0010] The preset blanching time t can be manually set by the user according to different types of ingredients and weights of ingredients.

[0011] Preferably, the preset blanching time t is automatically obtained by the intelligent cooking machine in the following manner:

[0012] Step 1, identifying and recording the types of ingredients that need to be blanched added to the intelligent cooking machine, and identifying and recording the weight of the ingredients that need to be blanched added to the intelligent cooking machine;

Cn is the specific heat capacity of the nth type of food that needs to be blanched in the smart cooking machine, and Mn is the weight of the nth type of food that needs to be blanched in the smart cooking machine; where n is the total number of types of food that needs to be blanched in the smart cooking machine at a time, and n is greater than or equal to 1; C 水 is the specific heat capacity of water, M 水 is the weight of water added to the smart cooking machine at a certain time when executing the blanching program; P is the heating power of the smart cooking machine when executing the blanching program; α is the first cooking correction coefficient, β is the second cooking correction coefficient, α and β are preset constants; T2 is the maximum temperature of the normal pressure blanching stage, which is a preset value, and the value range of T2 is 100℃~105℃; T1 is the initial temperature value of the blanching stage.

[0016] The preset temperature value can be pre-set by the user according to the type of food to be blanched, and the preset temperature value is 97°C ~ 100°C; it can also be pre-set by the intelligent cooking machine after automatically identifying the type of food to be blanched, and the preset temperature value is 97°C ~ 100°C.

[0017] The preset weight can be preset by the user according to the type and weight of the ingredients to be blanched, and the preset weight value is 4 to 10g; the preset temperature value can also be preset by the intelligent cooking machine after automatically identifying the type and weight of the ingredients to be blanched, and the preset temperature value is 97°C to 100°C.
