The first preparation time period is 3 days, the second preparation time period is 4 days, and the third preparation time period is greater than or equal to 7 days. Therefore, the preparation time is increased gradually, so that fungi can be better propagated and play a role in fermentation, and the efficiency and the quality of food preparation are improved.

Alternatively, the maturity of the food product is determined by the weight change of the food product. In this way, the water content of the food is evaporated along with the ripening process, and some substances are decomposed, so that the weight is continuously reduced, and the ripening degree of the food can be more accurately reflected through the change of the weight of the food.

Optionally, the food preparation mode comprises: a first preparation period, a second preparation period, and a third preparation period. After a 5% reduction in the weight of the food product in the first preparation period, the preparation of the food product proceeds to the second preparation period, and after a 10% reduction in the weight of the food product, the preparation of the food product proceeds to the third preparation period. Like this, food is mostly the reduction that the evaporation of moisture caused at the earlier stage weight, and fungus class begins to breed at this stage, gets into the second preparation time quantum after making the fungus class that ferments food have certain cardinal number, to the preliminary decomposition of food material, and fungus class begins stable growth, and the weight of food reduces 10%, can show that the growth of fungus class has got into stationary phase, gets into the third preparation time quantum, can ferment food at the third preparation time quantum of high efficiency under the accumulation of first two preparation time quantums, improves food preparation efficiency and quality.

Therefore, after the concentrated sterilization is carried out for a period of time, the growth of bacteria is inhibited, and then the machine is stopped for a longer period of time, so that the energy can be effectively saved.

Optionally, the ratio of the on-time operation duration to the off-time duration of the sterilization module is smaller as the ripening time of the food in the ripening partition is longer. Therefore, along with the development of the ripening process of the food in the ripening subarea, the starting time of the sterilization module is shortened or the stopping time of the sterilization module is prolonged, the sterilization strength is reduced, the sterilization effect can be effectively improved due to the fact that the food comprises more bacteria in the earlier stage of the ripening of the food, the food is prevented from going bad, and along with the increase of the ripening time of the food, the beneficial bacteria are propagated to generate a beneficial effect on the ripening process of the food, the sterilization strength is reduced at the moment, the effect of the beneficial bacteria is prevented from being influenced, and the quality of the cooked food is improved. For example, when the food in the ripening partition is ripened for 1 day, the time period for the sterilization module to start up is 1 hour, the time period for the sterilization module to stop up is 2 hours, and the ratio is one half, and when the food in the ripening partition is ripened for 5 days, the time period for the sterilization module to start up is 1 hour, the time period for the sterilization module to stop up is 4 hours, and the ratio is one quarter.

Optionally, the ripening time of the food in the ripening subarea is determined according to the weight change and/or freshness of the food in the ripening subarea; or determining the cooking time based on the length of time that the food in the cooking zone has elapsed since the start of preparation. Therefore, the ripening time of the food can be reflected according to the weight change or freshness of the food in the ripening subarea, namely, the ripening degree of the food can be reflected, so that the sterilization mode of the sterilization module in the ripening subarea is controlled, the food can be sterilized better in combination with the ripening degree, the sterilization effect is improved, the sterilization process is prevented from influencing the ripening of the food, the food preparation quality is improved, the time for starting the ripening of the food can be more simply and efficiently reflected by recording the elapsed time of the food in the ripening subarea after the food is prepared, the food ripening degree can be better reflected according to the time, the sterilization mode of the sterilization module is controlled, the judgment condition can be simplified, the running speed and the running stability of the processor are improved, the sterilization can be performed in combination with the ripening degree of the food, the sterilization effect is improved, and the sterilization process is prevented from influencing the ripening of the food, improve the quality of food preparation.

Therefore, new odor molecules can be generated after the food is decomposed or oxidized along with bacteria in the air, the odor molecules are obtained through the odor sensor, and the freshness of the food can be judged according to the concentration of the odor molecules, so that the freshness of the food in the ripening subarea can be judged efficiently and accurately.

Optionally, if a plurality of types of sterilization modules are disposed in the ripening partition, and the food preparation mode includes a plurality of preparation time periods, different preparation time periods being associated with different sterilization operation modes for different types of sterilization modules, the method further includes: determining the type of food in the ripening subarea, and determining a target sterilization module corresponding to the type of the food from the plurality of sterilization modules according to the type of the food; determining a sterilization operation mode of a sterilization module arranged in a cooking zone according to the cooking time of the food, comprising: and matching the actual preparation time period in which the ripening time of the food is positioned from the plurality of preparation time periods, and determining the actual preparation time period as the sterilization operation mode of the sterilization module aiming at the sterilization operation mode associated with the target sterilization module. Thus, the food preparation mode is divided into a plurality of preparation time periods, different sterilization operation modes are correspondingly associated with different types of sterilization modules in each time period, then the types of the food in the ripening subareas are determined, the sterilization modules needed in the food ripening process are determined according to the types of the food, different sterilization modules are adopted according to different foods, the sterilization is performed according to the types of the food, the sterilization modules are prevented from influencing the quality of the food, meanwhile, the actual preparation time period of the food is determined according to the food preparation time period in which the ripening time is positioned, the target sterilization module determined according to the types of the food is controlled to operate according to the sterilization operation mode corresponding to the actual preparation time period, the sterilization mode corresponding to the target sterilization module is ensured to operate in different time periods according to different foods, the sterilization efficiency is improved, and the bacteria are effectively prevented from exceeding the standard, ensuring the making quality of the cooked food.

Optionally, different sterilization modules correspond to different sterilization operation modes. Therefore, different sterilization operation modes are adopted due to different sterilization efficiencies of different sterilization modules, and the sterilization efficiency can be guaranteed to be high and stable.

Optionally, determining the type of food product within the ripening partition comprises: the food in the ripening partition is identified and the type of food is determined based on the image recognition means and/or the smell recognition means. In this way, the pattern of the food is identified by the image identification device, the type of the food is judged according to the pattern of the food, the odor molecules in the ripening subarea are detected by the odor identification device, the type of the food can be determined according to the odor molecules emitted by different foods, and the type of the food can be more accurately determined by combining the two modes, so that the error rate is reduced.

Optionally, the image recognition device includes a camera, and the image information of the food is acquired through the camera. In this way, the image information of the food is acquired by the camera and compared with the image information stored in the database, and the type of the food can be determined due to different appearances of different foods.

Optionally, the smell recognition device comprises an electronic nose device, and the smell information of the food is acquired through the electronic nose device. In this way, the odor information of the food is acquired through the electronic nose device and compared with the odor information stored in the database, and the type of the food can be determined due to different odors emitted by different foods.

Optionally, determining a target sterilization module corresponding to the type of the food from a plurality of sterilization modules according to the type of the food includes: determining that the target sterilization module is one of an ozone sterilization module, an ultraviolet sterilization module and a plasma sterilization module under the condition that the type of the obtained food is beef; under the condition that the type of the obtained food is pork, determining that the target sterilization module is an ultraviolet sterilization module; and under the condition that the type of the obtained food is tuna meat, determining the target sterilization module to be a plasma sterilization module. Therefore, when the food is beef, the beef is less in grease, and the influence of ozone sterilization, ultraviolet sterilization and plasma sterilization on the meat quality of the beef is less, so that any one of the ozone sterilization module, the ultraviolet sterilization module and the plasma sterilization module can be used for efficiently sterilizing the beef in the beef ripening process; when the type of the food is pork, because the fat content of the pork is high, and the influence of ozone sterilization and plasma sterilization on the fat is high, the ultraviolet sterilization is adopted in the pork curing process, so that the influence on the pork curing process can be reduced, and the sterilization efficiency is improved; when the type of the food is tuna meat, since the meat quality of the tuna is tender and ozone sterilization and ultraviolet sterilization have certain influence on the meat quality, the meat quality of the tuna meat after being ripened can be ensured by plasma sterilization, and the sterilization efficiency can be improved.

Alternatively, in the case where the type of food is beef, the sterilization is performed using the ozone sterilization module by default, and the use of the ultraviolet sterilization module or the plasma sterilization module may be changed according to the selection of the user.

Optionally, the plasma sterilization module operates with a plasma generation amount of 5 × 106 cubic centimeters. Therefore, the power control in the working process of the plasma sterilization module is in the range of 5 multiplied by 106 cubic centimeters of ion generation amount, so that a better sterilization effect can be obtained, a large amount of death of beneficial fermentation bacteria caused by over sterilization can be prevented, and the preparation quality of the cooked food is improved.

Optionally, in a case where it is determined that the type of the food is beef and the target sterilization module is an ozone sterilization module, controlling the corresponding sterilization operation mode of the ozone sterilization module includes: under the condition that the maturation time is less than or equal to 2 days, the ozone sterilization module is started for 1.0 hour intermittently, and stopped for 2.0 hours; under the condition that the maturation time is 2-7 days, the ozone sterilization module is intermittently started for 1.0 hour, and stopped for 4.0 hours; under the condition that the maturation time is 7-21 days, the ozone sterilization module is intermittently started for 0.5 hour and stopped for 4.0 hours; the maturation time is more than or equal to 21 days, the ozone sterilization module is intermittently started for 0.5 hour and stopped for 6.0 hours.
