Automatic baking control method for baking oven

Abstract

The invention discloses an automatic baking control method for a baking oven, which comprises the following steps: placing food to-be-baked into the baking oven, inserting a food temperature probe into the food, and starting a baking program corresponding to the food in the baking oven; (2), when a first baking stage set by the baking program is started, calculating the first real-time temperature change rate Delta T1 in a first time stage with a control module, and comparing the first real-time temperature change rate Delta T1 with a corresponding first predetermined temperature change rate Delta T1' in the baking program, so as to judge whether continuing heating is required or not; (3), when continuing heating is required and a second baking stage set by the baking program is started, calculating the second real-time temperature change rate Delta T2 in a second time stage with the control module, and comparing the second real-time temperature change rate Delta T2 with a corresponding second predetermined temperature change rate Delta T2' in the baking program, so as to judge whether continuing heating is required or not; the steps circulate till baking is fulfilled. As inner temperature change rates of food in specified time and final temperature value are adopted for adjusting total heating time, best baking time is selected, which ensures that meat foods of different initial attributes can be well baked.

Description

technical field [0001] The invention relates to a baking method, in particular to a method for controlling automatic baking of an oven. Background technique [0002] When a general oven bakes food, the operator needs to set the baking temperature, baking time, heating tube working mode, etc. of each stage of the oven according to the properties of the food and the desired baking results. High requirements, and usually require the operator to check the grilling status repeatedly, which will take up a lot of cooking time for the operator. [0003] For this reason, by setting sensor, the oven that utilizes the information fed back by the sensor to automatically bake has been invented, such as a kind of oven and its control method disclosed in Chinese patent application number 201010263062.3. An infrared temperature sensor for sensing food temperature in the cavity and a probe-type sensor arranged in the oven cavity. The infrared temperature sensor senses the surface temperatur...

Problems solved by technology

[0004] However, this baking method can only realize a simple automatic baking function, but for the same type of food with different initial attributes, such as food with different sizes and initial temperatures, the internal temperature of large food rises slowly, and the internal temperature of small food rises slowly. Fast, the baking time of large food reaches the predetermined temperature value is much longer than that of small food. If the small food is just cooked, the surface of the large food will inevitably be burnt; moreover, the internal temperature of food with different initial temperatures The time required to reach the preset value must also be different. The time required for the internal temperature of the food with a low initial temperature to reach the preset value must be longer. If the food with a high initial temperature is just cooked, then the internal temperature of the food with a low initial temperature reaches When the preset value is set, the outer surface is also likely to be burnt; it can be seen that the above-mentioned baking method cannot make some of the same type of food with the same final temperature, but different baking processes have a better baking effect
