When making baked products such as biscuits and bread, the products to be baked need to be placed one by one on a preheated lower baking tray, and the problem that the baking degree of the products to be baked which are placed first and the baking degree of the products to be baked which are placed later are different occurs.
Disclosure of Invention
The present invention is directed to solving at least one of the problems of the prior art.
To this end, a first aspect of the present invention is directed to a baking control method of a grill.
It is an object of a second aspect of the present invention to provide a roasting control apparatus for a grill.
A third aspect of the present invention is directed to a grill.
A fourth aspect of the invention is directed to a computer readable storage medium.
A fifth aspect of the present invention is directed to a grill.
In order to achieve the above object, an embodiment of an aspect of the present invention provides a baking control method of a frying and baking machine, where the frying and baking machine includes an upper baking tray, a first heating element for heating the upper baking tray, a lower baking tray, and a second heating element for heating the lower baking tray, the upper baking tray and the lower baking tray enclose a cooking cavity, the frying and baking machine further includes a tray for placing a product to be baked, and the tray can be placed in the cooking cavity and is located on the lower baking tray, and the method includes: step S10, controlling the first heating element to preheat the upper baking tray to a temperature T1, and controlling the second heating element to preheat the lower baking tray to a temperature T2, wherein T2 is greater than or equal to T1; step S20, after step S10, and after the tray on which the products to be baked are placed is placed on the lower baking tray, the first heating element is controlled to heat the upper baking tray to a temperature T3, the second heating element is controlled to heat the lower baking tray to a temperature T4, and the preset duration is maintained.
The baking control method of the frying and baking machine provided by the above embodiment of the present invention includes a preheating stage, in which the first heating element is controlled to preheat the upper baking tray so that the temperature of the upper baking tray reaches T1, and the second heating element is controlled to preheat the lower baking tray so that the temperature of the lower baking tray reaches T2. After the temperature of the upper baking tray reaches T1 and the temperature of the lower baking tray reaches T2, if the products to be baked are directly extruded one by one or placed on the upper surface of the preheated lower baking tray, the products to be baked which are placed first are heated more than the products to be baked which are placed later, so that the baking degrees of the products to be baked which are placed first and the products to be baked which are placed later are different, therefore, in order to ensure that the baking degrees of all the products to be baked are the same, when the upper baking tray and the lower baking tray are preheated in the preheating stage, the products to be baked are placed first on one tray, and after the frying and baking machine finishes preheating, the tray and the products to be baked are placed together in the cooking cavity for baking. Specifically, the product to be baked is placed on the tray firstly, the tray is placed on the lower baking tray after the temperature of the upper baking tray reaches T1 and the temperature of the lower baking tray reaches T2, and therefore the product to be baked can be placed on the lower baking tray at the same time.

After the temperature of the upper roasting tray 11 reaches T1 and the temperature of the lower roasting tray 21 reaches T2, if the products to be baked 5 are directly extruded one by one or placed on the upper surface of the preheated lower roasting tray 21, the products to be baked 5 placed first are heated more than the products to be baked 5 placed later, so that the baking degrees of the products to be baked 5 placed first and the products to be baked 5 placed later are different, therefore, in order to ensure that the baking degrees of all the products to be baked 5 are the same, when the upper roasting tray 11 and the lower roasting tray 21 are preheated in the preheating stage, the products to be baked are placed on one tray 4 first, and after the preheating of the frying machine 100 is completed, the tray 4 and the products to be baked 5 are placed into the cooking cavity 3 together for baking.

Since the tray 4 and the product 5 to be baked are in a normal temperature state before being placed in the frying and baking machine 100, when the tray 4 and the product 5 to be baked are placed on the lower roasting tray 21 preheated to T2 together, the tray 4 and the lower roasting tray 21 are directly contacted to rapidly absorb a large amount of heat of the lower roasting tray 21, so that the temperature of the lower roasting tray 21 is rapidly reduced. In order to ensure that the temperature of the lower roasting tray 21 after the heat neutralization and balance with the tray 4 can be close to the control temperature T4 of the lower roasting tray 21 in the roasting stage after the tray 4 is placed in, the control temperature T2 of the lower roasting tray 21 in the preheating stage needs to be set to be slightly higher, so that T2 is greater than or equal to the control temperature T1 of the upper roasting tray 11 in the preheating stage.
The tray 4 includes a tray body 41 for containing the food 5 and a grip portion 42 connected to the tray body 41.
