Description

Technical Field

[0001] This application relates to the field of refrigerator low-temperature storage technology, specifically to a method and apparatus for low-temperature food processing in a refrigerator. Background Technology

[0002] When storing food at low temperatures, some refrigerators use micro-freezing / microcrystallization technology. Micro-freezing / microcrystallization refers to storing food at a temperature slightly below its freezing point. At this temperature, the moisture in the food is partially frozen, resulting in lower hardness, easier control, and the food can be stored for a certain period. However, when using micro-freezing / microcrystallization technology to store food, firstly, ice crystals will form in the food, which can damage its quality; secondly, since the food being micro-frozen is mostly at the same temperature as the ambient temperature, its temperature is relatively high. The slow cooling rate of micro-freezing / microcrystallization technology makes it easier for larger ice crystals to form, which is detrimental to maintaining food quality. Furthermore, it accelerates the drying out and freeze-burning of food, causing oxidation or damage to proteins, resulting in a decline in food quality. Summary of the Invention

[0032] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0033] When using microfreezing / microcrystallization technology to store food, firstly, ice crystals will form in the food, which will damage the quality of the food; secondly, since the food being microfrozen is mostly at the same temperature as the environment, the temperature is relatively high, and the microfreezing / microcrystallization technology cools down slowly, which makes it easier to form larger ice crystals, which is not conducive to maintaining the quality of the food, and will also accelerate the drying and freeze-burning of the food, resulting in a decline in the quality of the food.

[0034] To address the issue of food quality degradation during low-temperature storage, some embodiments of this application provide a method for low-temperature food processing in a refrigerator. (See attached document.) Figure 1-2 , Figure 1 This is a flowchart of a refrigerator food low-temperature treatment method provided in an embodiment of this application. Figure 2 This is a schematic diagram of a refrigerator food low-temperature treatment method provided in an embodiment of this application. The treatment method provided in this application includes:

[0035] S100: Obtain the first temperature inside the functional room and the food information of the ingredients inside the functional room.

[0036] In some embodiments, a separate functional compartment can be set up in the refrigerator. A temperature sensor collects the initial temperature within the functional compartment and sends it to the refrigerator's controller. The acquired food information includes food weight and food temperature. A weight sensor and a food temperature sensor can be installed at the bottom of the functional compartment, with the weight sensor collecting the food weight. A plate-like structure made of a high thermal conductivity material, such as aluminum, copper, or graphene, can be installed at the bottom of the functional compartment to contact the food, with the food temperature sensor collecting the food temperature. It should also be noted that an electric field module is installed in the functional compartment to release a high-frequency electric field, with a release frequency of 40kHz to 70kHz.

[0037] S200: Obtain the supercooling matching temperature of the food based on its weight.

[0038] Since the storage temperature of food is affected by its weight, the supercooling matching temperature is different for food of different weights. The supercooling matching temperature is the temperature at which the food can be quickly cooled to the freezing point based on its weight. The refrigerator controller is set with a supercooling matching temperature that matches the weight of the food. The controller outputs the supercooling matching temperature that matches the weight of the food based on the received food weight information. In some embodiments, the range of the food supercooling matching temperature is -18℃ to -39℃.

[0039] S300: If the temperature of the food is greater than the theoretical freezing point of the food, the control function compartment will operate according to the first preset rule.

[0040] The first preset rule includes: if the first temperature is greater than or equal to the theoretical freezing point temperature, the control function room operates according to the second temperature; if the first temperature is less than the theoretical freezing point temperature, the control function room operates according to the subcooling matching temperature.

[0041] The theoretical freezing point temperature refers to the temperature at which the moisture in food begins to freeze. The theoretical freezing point temperature of food is 0°C. It can be understood that the theoretical freezing point temperature of food is greater than its supercooling matching temperature. Since defrosting in the functional compartment will cause the temperature inside the compartment to rise, if the first temperature inside the functional compartment is greater than or equal to the theoretical freezing point temperature of the food (0°C), the functional compartment is controlled to operate at the second temperature. In this embodiment, the second temperature is the same as the supercooling matching temperature and / or the preset temperature of the functional compartment. The preset temperature is the minimum set temperature of the functional compartment and is less than the supercooling matching temperature of the food; for example, the preset temperature could be -40°C.

[0042] It is understandable that the second temperature is lower. In order to quickly reduce the first temperature in the functional room to the second temperature, in some embodiments, if the first temperature is greater than or equal to the theoretical freezing point, the method of controlling the functional room to operate at the second temperature includes:

[0043] S311: Obtain the fourth temperature in other rooms.

[0044] It should be noted that the fourth temperature can be the temperature of a single compartment or a combination of temperatures of multiple compartments.

[0045] S312: If the fourth temperature is lower than the critical temperature of other compartments, control the other compartments to operate at the critical temperature, and / or control the cooling mode of other compartments to be turned off.

[0046] By controlling the cooling temperature of other compartments and / or turning off the cooling mode of other compartments, most of the refrigerator's cooling capacity is provided to the functional compartments, so that the functional compartments can be quickly cooled to the second temperature.

[0047] In the aforementioned first preset rule, whether the functional compartment operates at the supercooling matching temperature or the preset temperature also depends on the weight of the ingredients. Therefore, in some embodiments, after the step of controlling the functional compartment to operate at the second temperature if the first temperature is greater than or equal to the theoretical freezing point, the method further includes: controlling the functional compartment to operate according to the second preset rule based on the weight of the ingredients. The second preset rule includes: if the weight of the ingredients is greater than a weight threshold, controlling the functional compartment to operate at the preset temperature; if the weight of the ingredients is less than the weight threshold, controlling the functional compartment to operate at the supercooling matching temperature.

[0048] If the first temperature in the functional room is lower than the theoretical freezing point, it means that the temperature in the functional room is already below 0℃ and the temperature is too low. The functional room can be directly controlled to operate according to the subcooling matching temperature.

[0049] S400: When the temperature of the food is lower than the theoretical freezing point but higher than the supercooling point of the food, the control function compartment operates at the third temperature.

[0050] The supercooling point temperature of food is its actual freezing temperature, also known as its critical freezing temperature. Influenced by inorganic salts, sugars, or other organic acids in the food, the actual freezing temperature, i.e., the supercooling point temperature, is lower than the theoretical freezing point temperature. For example, the supercooling point temperature of food is typically around -2℃ to -3℃. It can be understood that the supercooling point temperature is higher than the supercooling matching temperature. When the temperature of the functional compartment drops rapidly, the temperature of the food will also drop rapidly. When the food temperature drops to between the theoretical freezing point temperature and the supercooling point temperature, the functional compartment is controlled to operate at a third temperature. In this embodiment, the third temperature is the temperature between the theoretical freezing point temperature and the supercooling point temperature. For example, if the supercooling point temperature of the food is -3℃, when the food temperature drops to -2℃, the refrigerator's functional compartment can be controlled to operate at -2℃ to prevent ice crystals from forming inside the food.

[0051] In this embodiment, when both the food temperature and the temperature inside the functional room are high, the functional room is controlled to operate at a lower temperature so that the food can be cooled down quickly. By cooling down quickly, the moisture in the food is supercooled at the critical temperature instead of forming ice crystals, which can maintain the storage quality of the food. At the same time, it can also lower the supercooling point temperature of the food, which is more conducive to storing the food at a lower temperature without forming ice crystals.

[0052] As can be seen from the above embodiments, when the food temperature is between the theoretical freezing point and the supercooling point, the food is already in a supercooled state. Therefore, the processing method further includes: if the food temperature is lower than the theoretical freezing point but higher than the supercooling point, the functional compartment is controlled to operate at a third temperature. That is, regardless of the first temperature in the functional compartment, the controller controls the functional compartment to operate at the third temperature to keep the food in a supercooled state, while controlling other compartments to operate at a fourth temperature.

[0053] In some embodiments, the food placed in the compartment may also be frozen food. Therefore, the processing method of this application embodiment further includes: if the temperature of the food is lower than the supercooling point temperature, controlling the functional compartment to operate at a first temperature and / or a third temperature. When the temperature of the food is lower than the supercooling point temperature, since ice crystals have already formed in the food and cannot be eliminated, the functional compartment is controlled to operate at the obtained first temperature, which is the current temperature, and / or the functional compartment is controlled to operate at the third temperature, so that the ice crystals in the food will no longer continue to grow, but will only continue to form more small-sized ice crystals, so as to reduce the damage to the quality of the food caused by large-sized ice crystals.

[0054] During storage, users may frequently open or close the refrigerator door when accessing food, causing fluctuations in food temperature. In some embodiments, the method further includes: if the food temperature fluctuates during storage and exceeds the food's supercooling point temperature, controlling the functional compartment to operate at a preset temperature and / or a supercooling matching temperature; and when the food temperature drops to between the theoretical freezing point temperature and the supercooling point temperature, controlling the functional compartment to operate at a third temperature.

[0055] S500: Sends an activation command to the electric field module to control the electric field module to turn on.

[0056] Once the electric field module is activated, it releases a high-frequency electric field with a frequency of 40kHz to 70kHz. This high-frequency electric field influences the dipole moment of water molecules, limiting the formation of critical molecular clusters. Under the influence of the high-frequency electric field, the food that has reached a supercooled state is maintained in a supercooled state, thus preventing the formation of ice crystals inside the food and avoiding damage to the quality of the food caused by the formation of ice crystals.
