Description

Technical Field

[0001] The present application relates to the field of food processing, and in particular to an automatic control method and system for food processing. Background Art

[0002] At present, food processing is to process raw grains or other ingredients through artificial processing to form a new form of directly edible products, among which frying is one of the most commonly used food processing methods. In the back kitchens of many fast food restaurants, fryers are available to make fried foods.

[0003] During the frying process, if there is too little cooking oil in the oil tank, the food is not easy to fry thoroughly. When there is too much cooking oil in the oil tank, if the user puts a large amount of food into the oil tank, the cooking oil will overflow from the oil tank. When the cooking oil has been used for too long, it needs to be replaced to ensure food safety.

[0004] With respect to the above-mentioned related technology, the inventors found that there are at least the following problems in the technology: during the frying process, the user needs to always pay attention to the amount of oil in the oil tank. When the amount of oil is low, it is necessary to add an appropriate amount of oil in time, which makes it inconvenient for the user to operate during the food processing process. Summary of the invention

[0005] In order to help improve the problem of troublesome operations for users during food processing, the present application provides an automatic control method and system for food processing.

[0006] In a first aspect, the present application provides an automatic control method for food processing, which adopts the following technical solution:

[0007] The method comprises:

[0008] Obtaining oil level information sent by a liquid level detection terminal, wherein the oil level information includes an oil level height;

[0009] Comparing the oil level with the oil level corresponding to the preset oil filling level;

[0010] When the oil level is lower than the oil level corresponding to the preset oil filling level, the remaining oil volume corresponding to the oil level is calculated according to the oil level, the oil level of the standard oil level and the oil volume corresponding to the standard oil level;

[0011] The amount of oil to be replenished from the oil level to the standard oil level is calculated based on the remaining oil amount and the oil amount corresponding to the standard oil level;

[0012] Determining the oil replenishment time according to the oil replenishment amount and the preset oil replenishment rate;

[0013] Outputting fuel replenishment information, wherein the fuel replenishment information includes the calculated fuel replenishment time.

[0014] By adopting the above technical solution, during the processing, the control center can automatically detect the situation that the oil level of the edible oil in the frying furnace body is too low, and automatically calculate the time for oil replenishment, so that the frying furnace body replenishes oil according to the oil replenishment time until the edible oil is automatically added to the standard oil level, thereby reducing the possibility of users manually judging the oil level and manually replenishing oil, and facilitating the operation of users in the process of processing food. At the same time, the frying furnace body is replenished with oil according to the oil replenishment time, instead of using the liquid level detection terminal to detect the liquid level in real time. The oil replenishment is completed when the liquid level rises to the standard oil level. The oil replenishment port is usually higher than the standard liquid level. When the liquid level rises to the standard oil level, some edible oil has still flowed out of the oil replenishment port but has not reached the liquid surface. Stopping the oil replenishment at this time is likely to cause excessive oil replenishment, thereby reducing the accuracy of the edible oil level control. Replenishing oil according to the oil replenishment time reduces the possibility of excessive oil replenishment, and at the same time helps to improve the accurate control of the edible oil level.

[0015] Optionally, before acquiring the oil level information sent by the liquid level detection terminal, the method further includes:

[0016] receiving a food processing list, wherein the food processing list includes food names arranged in a preset order;

[0017] Querying the processing information corresponding to the food name in a preset food processing database, wherein the processing information includes processing temperature, processing time and taste information;

[0018] Adjust the food processing list according to the taste information so that the food names are arranged according to the taste information;

[0019] Add the food name corresponding to the processing information to the food processing list, generate and output an updated food processing list;

[0020] The step of obtaining the oil level information sent by the liquid level detection terminal includes:

[0021] When the food out-of-the-fryer information sent by the frying furnace body is received, the oil level information sent by the liquid level detection terminal is obtained.

[0022] By adopting the above technical solution, the frying furnace body can process food in an orderly manner according to the food processing list. Each time a processing is completed, the control center obtains the oil level information, and replenishes oil when the oil level is too low. The oil replenishment is performed automatically, which helps to reduce the possibility of oil temperature changes caused by oil replenishment during the processing process affecting the taste of the processed food.

[0023] Optionally, the food out-of-the-oven information includes a food name, and the food out-of-the-oven information is single processing completion information or food processing completion information. Before adding the food name corresponding to the processing information to the food processing list, it also includes:

[0024] Arrange the names of foods with the same taste information from low to high according to their corresponding processing temperatures;

[0025] The step of obtaining the oil level information sent by the liquid level detection terminal includes:

[0026] If the food out-of-the-oven information is food processing completion information, the food name in the food processing completion information is searched in the food list to find the next food name in sequence;

[0027] If the taste information corresponding to the queried food name is different from the taste information of the food name in the food processing completion list, output an oil change instruction and make the oil level reach the standard oil level;

[0028] Otherwise, obtain the oil level information sent by the liquid level detection terminal.

[0029] By adopting the above technical solution, when the control center detects that the taste information of the next food to be processed has changed, the frying furnace body can be automatically controlled to change the oil, thereby helping to reduce the possibility of food odor contamination during processing. After the oil is changed, the oil temperature of the new oil is relatively low, and the food names are arranged from small to large according to the corresponding processing temperature, which helps to shorten the preheating time of the frying furnace body and helps the frying furnace body to start processing food as soon as possible after the oil is changed, thereby helping to reduce the possibility of reduced processing efficiency due to oil change.

[0030] Optionally, before outputting the oil change instruction, the method further includes:

[0031] Acquire and store the oil quality information of the reused oil sent by the oil quality detection terminal, wherein the oil quality information includes parameter values ​​corresponding to the oil quality parameters;

[0032] Comparing the parameter value corresponding to the oil quality parameter with the preset parameter threshold value;

[0033] If the oil quality parameters are all within the standard range, a reuse oil storage instruction is output, and the storage instruction includes the taste information of the food name in the food processing completion information.

[0034] By adopting the above technical solution, the control center can analyze the edible oil according to the oil quality information sent by the oil quality detection terminal. If it is determined that the edible oil has been used for a long time and is not suitable for reuse, the edible oil will be drained and replaced with new oil; if the edible oil has been used for a short time and is suitable for reuse, the edible oil will be stored and replaced with new oil to facilitate the reuse of the edible oil when processing food with the same taste information next time, thereby ensuring food safety while reducing oil waste.

[0035] Optionally, after the output of the reuse oil storage instruction, the method further includes:

[0036] generating a reused oil storage record, wherein the reused oil storage record includes the taste information of the reused oil and the amount of new oil added to replenish the oil level corresponding to the reused oil to the standard liquid level;

[0037] The output oil change instruction includes:

[0038] Querying the storage record of the reused oil corresponding to the taste information;

[0039] If the storage record of the reused oil corresponding to the taste information is found, the reused oil usage information is output, and the reused oil usage information includes the taste information;

[0040] Deleting the storage record of the reused oil corresponding to the taste information found;

[0041] The oil replenishment information is output, wherein the oil replenishment information includes the oil replenishment amount in the reuse oil storage record.

[0042] By adopting the above technical solution, when the oil needs to be changed, the control center inquires whether reusable edible oil with the same taste information is stored. If so, the edible oil is reused and new oil is added to make the oil level reach the standard oil level, thereby realizing the reuse of the edible oil.

[0043] Optionally, when the oil quality information of the reused oil sent by the oil quality detection terminal is acquired and stored, the acquisition time corresponding to the oil quality information is recorded;

[0044] The output reuse oil storage instruction includes:

[0045] deriving a parameter value change according to the parameter value in the oil quality information of the reused oil and the parameter value in the last stored oil quality information of the reused oil;

[0046] Calculate the time length from the time corresponding to the oil information to the time corresponding to the previous oil quality information as the parameter change time length of the reused oil;

[0047] Calculating the parameter change rate according to the parameter value change amount and the calculated parameter change duration of the composite oil;

[0048] Obtaining preset initial parameter values ​​corresponding to oil quality parameters of new oil;

[0049] Calculate the mixed oil parameter value corresponding to the oil quality parameter of the mixed oil obtained by mixing the reused oil with the new oil of the replenished oil amount according to the initial parameter value, the replenished oil amount, the remaining oil amount corresponding to the reused oil, and the oil quality parameter value;

[0050] Calculate the time required for each grease parameter corresponding to the mixed oil to reach the parameter threshold value according to the obtained parameter value change rate;

[0051] The minimum time among the calculated times is selected as the available time of the mixed oil;

[0052] If the available time of the mixed oil is greater than a preset time threshold, a reuse oil storage instruction is output.

[0053] By adopting the above technical scheme, when the oil quality detector detects that the oil quality is qualified and can be reused, the control center calculates the parameter value change rate of each oil quality parameter, and calculates the parameter value of the mixed oil when the edible oil at this time is stored as reused oil, and the reused oil is used and new oil is added until the standard liquid level is obtained when the mixed oil is obtained during the oil change. According to the parameter value of the mixed oil and the parameter value change rate, the use time of the mixed oil is obtained. The mixed oil can be used for a shorter time, that is, the edible oil is used for a shorter time when it is reused and new oil needs to be added, which may cause waste of new oil. The control center automatically discharges the edible oil at this time and no longer reuses the edible oil at this time.

[0054] Optionally, the method further includes:

[0055] When an oil change or oil replenishment instruction is output, the time of sending is recorded as the grease update time;

[0056] After obtaining the preset initial parameter value corresponding to the oil quality parameter of the new oil, the method further includes:

[0057] Calculate the time length between the time corresponding to the grease information and the previous grease update time as the usage time of the reused oil;

[0058] The time required for each grease parameter corresponding to the new oil to reach the parameter threshold is calculated according to the obtained parameter value change rate;

[0059] The minimum time among the calculated times is selected as the usable time of the new oil;

[0060] The total usage time of the oil change is obtained by adding the usable time of the new oil to the usage time of the reused oil;

[0061] After selecting the minimum time from the calculated times as the available time of the mixed oil, the method further includes:

[0062] The total reuse time is obtained by adding the use time of the mixed oil to the use time of the reuse oil;

[0063] The total reused oil volume is obtained by adding the replenished oil volume to the standard oil volume;

[0064] Divide the total reused oil volume by the total reused usage time to get the reused oil consumption per unit time;

[0065] Adding the standard oil quantity to the standard oil quantity yields a total oil quantity for oil change;

[0066] The total oil volume of the oil change is divided by the total usage time of the oil change to obtain the oil consumption per unit time of the oil change;

[0067] If the oil consumption per unit time of oil change is greater than the oil consumption per unit time of oil replenishment, a reuse oil storage instruction is output.

[0068] By adopting the above technical scheme, when the oil quality tester detects that the oil quality is qualified and can be reused, the control center can calculate the corresponding oil consumption per unit time under the two schemes of directly discharging the edible oil at this time and replacing it with new oil when changing the oil in the future, and storing the edible oil at this time and reusing the stored edible oil and replenishing it to the standard oil level when changing the oil next time. The control center selects the scheme with lower oil consumption per unit time, thereby making the judgment on whether the edible oil needs to be reused more accurate and improving intelligence.

[0069] Optionally, before acquiring the oil level information sent by the liquid level detection terminal, the method further includes:

[0070] receiving a melt oil request, wherein the melt oil request includes a grease name;

[0071] Querying the melt temperature corresponding to the grease name in the melt request in a preset grease information database;

[0072] outputting a melt oil instruction, wherein the melt oil instruction includes the queried melt oil temperature;

[0073] Before comparing the oil level with the oil level corresponding to the preset oil replenishment level, the method further includes:

[0074] Retrieve historical oil level information sent by the liquid level detection terminal within a preset time range;

[0075] If the oil level in the historical oil level information shows an upward or downward trend, an oil melting reminder is output;

[0076] The variance of the oil level height measured within a preset time range is calculated until the variance is less than a preset error threshold, and then the oil melting completion information is output.

[0077] By adopting the above technical solution, when the edible oil is solid, the control center controls the terminal to melt the oil, and can automatically determine whether the melting of the oil is completed. When it is determined that the melting of the oil is completed, the melting completion information is automatically output to remind the user that the melting of the oil is completed. When the liquid level detection terminal measures the height of the liquid oil in the melting process, the oil level of the liquid oil increases as it melts, indicating that the oil is still melting; if the liquid level detection terminal measures the temperature of the solid oil in the melting process due to the position relationship, the height of the solid oil decreases as it melts, so that the liquid level detection terminal is suitable for different situations.

[0078] In a second aspect, the present application provides an automatic control system for food processing, which adopts the following technical solution: characterized in that the system comprises:

[0079] An information acquisition module, used to acquire the oil level information sent by the liquid level detection terminal, wherein the oil level information includes the oil level height;

[0080] A height comparison module compares the oil level with the oil level corresponding to a preset oil filling level;

[0081] An oil quantity calculation module, for calculating the remaining oil quantity corresponding to the oil level height according to the oil level height, the oil level height of the standard oil level and the oil quantity corresponding to the standard oil level when the oil level height is lower than the oil level height corresponding to the preset oil replenishment level;

[0082] The oil quantity calculation module is also used to calculate the amount of oil to be replenished from the oil level to the standard oil level through the remaining oil quantity and the oil quantity corresponding to the standard oil level;

[0083] A time calculation module, used to calculate the refueling time according to the refueling amount and the preset refueling rate;

[0084] The information sending module is used to output the refueling information, wherein the refueling information includes the calculated refueling time.

[0085] By adopting the above technical solution, during the processing, the control center can automatically detect the situation that the oil level of the edible oil in the frying furnace body is too low, and automatically calculate the time for oil replenishment, so that the frying furnace body replenishes oil according to the oil replenishment time until the edible oil is automatically added to the standard oil level, thereby reducing the possibility of users manually judging the oil level and manually replenishing oil, and facilitating the operation of users in the process of processing food. At the same time, the frying furnace body is replenished with oil according to the oil replenishment time, instead of using the liquid level detection terminal to detect the liquid level in real time. The oil replenishment is completed when the liquid level rises to the standard oil level. The oil replenishment port is usually higher than the standard liquid level. When the liquid level rises to the standard oil level, some edible oil has still flowed out of the oil replenishment port but has not reached the liquid surface. Stopping the oil replenishment at this time is likely to cause excessive oil replenishment, thereby reducing the accuracy of the edible oil level control. Replenishing oil according to the oil replenishment time reduces the possibility of excessive oil replenishment, and at the same time helps to improve the accurate control of the edible oil level.

[0086] In a third aspect, the present application provides a computer device, which adopts the following technical solution: it includes a memory and a control center, and the memory stores a computer program that can be loaded by the control center and execute any of the above-mentioned automatic control methods for food processing.

[0087] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: storing a computer program that can be loaded by a control center and execute any of the above-mentioned automatic control methods for food processing.

[0088] In summary, the present application includes at least one of the following beneficial technical effects:

[0089] 1. During the processing, the control center can automatically detect that the oil level in the fryer is too low, and automatically calculate the time to add oil, so that the fryer can add oil according to the oil-adding time until the edible oil is automatically added to the standard oil level, thereby reducing the possibility of users manually judging the oil level and adding oil manually, and facilitating the user's operation during food processing. At the same time, the fryer can be refilled according to the oil-adding time, rather than using the liquid level detection terminal to detect the liquid level in real time. The oil-adding port is usually higher than the standard liquid level. When the liquid level rises to the standard oil level, some edible oil has still flowed out of the oil-adding port but has not reached the liquid surface. Stopping the oil-adding at this time can easily cause excessive oil-adding and reduce the accuracy of the edible oil level control. Refilling oil according to the oil-adding time reduces the possibility of excessive oil-adding and helps to improve the accuracy of the edible oil level control.

[0090] 2. When the oil quality tester detects that the oil quality is qualified and can be reused, the control center can calculate the corresponding oil consumption per unit time under the two schemes of directly discharging the cooking oil at this time and replacing it with new oil when changing the oil in the future, and storing the cooking oil at this time and reusing the stored cooking oil and replenishing it to the standard oil level when changing the oil next time. The control center selects the scheme with lower oil consumption per unit time, thereby making the judgment on whether the cooking oil needs to be reused more accurate and improving intelligence.

[0096] The present application discloses an automatic control method for food processing. The method is based on an intelligent deep fryer, comprising a deep fryer body and a control center, the control center can be a control chip, having communication and data processing functions, the deep fryer body receives a signal output by the control center, the control center sends the output signal to the deep fryer body to control the deep fryer, the deep fryer can be equipped with a display screen, the display screen and the control center can transmit signals, and the user can directly input operations on the display screen on the deep fryer.

[0097] In one embodiment, Figure 1 As shown, an automatic control method for food processing is provided, the method comprising the following steps:

[0098] S10, obtaining oil level information sent by the liquid level detection terminal.

[0099] Specifically, the frying furnace includes an oil pan for frying food, and the liquid level detection terminal can be a liquid level detector, which is arranged above the oil pan to detect the oil level in the oil pan. The liquid level detection terminal sends the detected oil level information to the control center, and the control center obtains the oil level information, which includes the oil level height in the oil pan.

[0100] S11, when the oil level is lower than the oil level corresponding to the preset oil replenishment level, the remaining oil volume corresponding to the oil level is calculated.

[0101] Specifically, the control center compares the received oil level with the preset oil level corresponding to the oil filling level. When the received oil level is lower than the oil level corresponding to the oil filling level, it indicates that the oil pan needs to be filled with oil. The control center calculates the remaining oil volume corresponding to the oil level based on the oil level, the standard oil level and the oil volume corresponding to the standard oil level.

[0102] S12, calculating the amount of oil to be replenished from the oil level height to the standard oil level.

[0103] Specifically, the control center calculates the amount of oil that needs to be replenished from the oil level to the standard oil level based on the remaining oil amount and the oil amount corresponding to the standard oil level.

[0104] S13, calculating the oil replenishment time according to the oil replenishment amount and the preset oil replenishment rate.

[0105] Specifically, when refueling, the oil output rate is constant, and the control center calculates the refueling time based on the amount of oil to be replenished and the refueling rate.

[0106] S14, outputting oil replenishment information.

[0107] Specifically, the control center outputs the oil replenishment information, which includes the calculated oil replenishment time, so that the frying furnace body automatically stops replenishing oil when the oil replenishment time is reached. After the oil replenishment stops, the oil level reaches the standard oil level, thereby realizing automatic oil replenishment. At the same time, the frying furnace body is replenished with oil according to the oil replenishment time. Compared with the commonly used oil replenishment method of using a liquid level detection terminal to detect the liquid level in real time and completing the oil replenishment when the liquid level rises to the standard oil level, the oil replenishment based on time can achieve more accurate control of the edible oil level. Since the oil replenishment port is usually higher than the standard liquid level, when the liquid level rises to the standard oil level, some edible oil has still flowed out of the oil replenishment port but has not reached the liquid surface. Even if the oil replenishment is stopped at this time, it is easy to cause excessive oil replenishment, thereby reducing the accuracy of edible oil level control.

[0108] In one embodiment, if oil is added during the processing, it will cause changes in oil temperature, affecting the taste of the processed food. When a user needs to process food, the user can input the name of the food to be processed through the display screen. All the names of the food to be processed constitute a food processing list, and the control center receives the food processing list input locally. In the preset food processing database, each food name is associated with and stored with processing information, and the processing information includes processing temperature, processing time, and taste information. For example, the taste information can be spicy, spiced, etc. The control center puts the food names with the same taste information together, thereby completing the adjustment of the food processing list according to the taste information.

[0109] The control center queries the processing information corresponding to each food name in the food processing database, and adds the processing information to the food processing list. The control center outputs the modified food processing list to the fryer body, and the fryer body processes the food according to the received food processing list. After the fryer body finishes processing a pot of food, it will send food out-of-the-oven information to the control center. The food out-of-the-oven information is a single processing completion information or food processing completion information. The control center receives the food out-of-the-oven information, which includes the corresponding food name. When receiving the food out-of-the-oven information, the control center obtains the oil level information released by the liquid level detection terminal, and judges the oil level information to determine whether oil needs to be added. In this way, the fryer body can process the food in sequence, and judge whether oil needs to be added in the interval between each pot of food processing.

[0110] If oil needs to be added, the control center automatically controls the frying furnace body to add oil. After the oil is added, the edible oil is heated according to the processing temperature of the food name corresponding to the currently processed food until the edible oil is heated to the processing temperature and the processing continues.

[0111] In one embodiment, considering that foods corresponding to food names with different flavors may have mixed flavors during processing, the control center puts the food names with the same flavor information together, and then arranges the food names corresponding to the same flavor information from low to high according to the corresponding processing temperatures.

[0112] If the food out-of-the-oven information sent by the frying furnace body to the control center is food processing completion information, it includes the name of the food that has been added. After the control center receives the food processing completion information, it means that the food corresponding to a food name has been processed, and the control center queries the food name that is next in order to the processed food name in the food processing list. The control center determines whether the taste information corresponding to the queried food name is the same as the taste information of the processed food name. If so, the oil level information sent by the liquid level detection terminal is obtained, and the oil is replenished according to the oil level information until the standard oil level is reached; otherwise, the oil change instruction is output. The oil change instruction refers to the information that the oil in the oil pan is drained and replaced with new oil in the oil pan, so that the oil level of the new oil in the oil pan reaches the standard oil level, thereby reducing the possibility of cross-flavoring between foods of different flavors during the processing process.

[0113] It is worth noting that if the food out-of-the-oven information sent by the fryer body is a single processing completion information, including the name of the food that has been added, then the oil refilling information will be output until the oil level reaches the standard oil level.

[0114] In another embodiment, considering that when the amount of food corresponding to each flavor of food name is small, the oil pan will need to drain and replace the oil frequently, which may easily cause waste of edible oil. Whenever the control center receives the information of food coming out of the oven, it obtains the oil quality information sent by the oil quality detection terminal. The oil quality information includes the parameter value corresponding to the oil quality parameter. The oil quality detection terminal can be an edible oil detector. The oil quality parameter can include oil quality parameters such as acid value, peroxide value, purity, etc. The control center compares the parameter value corresponding to each oil quality parameter with the preset parameter threshold corresponding to each oil quality parameter.

[0115] If the food out-of-the-oven information is the completion information of a single processing, and the parameter values ​​corresponding to all oil quality parameters are within the parameter threshold, the oil replenishment information is output; otherwise, the oil change instruction is output to replace the new oil in the oil pan so that the oil level of the new oil in the oil pan reaches the standard oil level.

[0116] If the food out-of-the-oven information is food processing completion information, and the control center determines that the taste information corresponding to the next processed food name is different from the taste information of the processed food name, if the parameter values ​​corresponding to all oil quality parameters do not reach the parameter threshold, a storage instruction is output to the frying furnace body, and the storage instruction includes the taste information of the processed food name, and then an oil change instruction is output to the frying furnace body, and the frying furnace body first stores the reused oil in the oil pot, and adds new oil after the oil pot is emptied; otherwise, an oil change instruction is directly output, and the frying furnace body directly empties the oil pot and adds new oil. The frying furnace body stores edible oil according to the storage instruction for easy reuse, thereby reducing the waste of edible oil caused by oil change, and can ensure food safety to a certain extent.

[0117] In another embodiment, considering the situation that it is necessary to control the frying furnace body to reuse the stored reused oil at an appropriate time, each time the control center outputs a storage instruction to the frying furnace body, a reused oil storage record will be generated. The reused oil storage record includes the taste information corresponding to the reused oil and the amount of oil required to replenish the reused oil to the standard amount of oil. When the control center determines that the taste information corresponding to the name of the next processed food is different from the taste information of the name of the processed food, the control center queries the reused oil storage record corresponding to the taste information. If the corresponding reused oil storage record can be queried, the reused oil usage information is output to the frying furnace body; otherwise, the oil change instruction is directly output. The reused oil usage information includes the taste information, and the frying furnace body is controlled to automatically retrieve the reused oil with the same taste information stored, add the reused oil into the oil pan, and then output the oil replenishment instruction to the frying furnace body to mix the new oil with the reused oil so that the amount of oil in the oil pan reaches the standard amount of oil. After outputting the reused oil usage information to the frying furnace body, the controller deletes the corresponding reused oil storage record. Whenever grease is stored, a reuse oil storage record is created.

[0118] In one embodiment, considering that the quality of the reused oil may be close to being unusable, if new oil is added to the standard oil level to obtain mixed oil, the mixed oil can be used for a short time, which may easily cause waste of the added new oil. Whenever the control center obtains and stores the oil quality information of the reused oil sent by the oil quality detection terminal, the control center records the acquisition time corresponding to the oil quality information. The control center obtains the preset initial parameter value corresponding to the oil quality parameter of the unused grease.

[0119] The control center obtains the parameter value change of each oil parameter based on the parameter value in the oil quality information of the reused oil this time and the parameter value in the oil quality information of the last reused oil stored; the control center calculates the time length from the time corresponding to the current oil information of the reused oil to the time corresponding to the last oil quality information as the parameter change duration of the reused oil; the parameter change rate is obtained based on the parameter value change and the calculated parameter change duration. The control center calculates the mixed oil parameter value corresponding to the oil quality parameter of the mixed oil obtained by mixing the remaining oil amount with the replenished oil amount based on the initial parameter value, the replenished oil amount, the remaining oil amount, and the oil quality parameter value in the oil quality information. The calculation method of a single mixed oil parameter value can be: mixed oil parameter value = (initial parameter value * replenished oil amount + oil quality parameter value * mixed oil amount) / (replenished oil amount + remaining oil amount).

[0120] The control center calculates the time required for each oil parameter corresponding to the mixed oil to reach the parameter threshold value based on the obtained parameter value change rate, and selects the minimum time from the calculated time as the available time of the mixed oil. If the available time of the mixed oil is greater than the preset time threshold, the reuse oil storage instruction is output to the fryer body, and then the oil change instruction is output; otherwise, the oil change instruction is directly output to the user terminal, and the edible oil in the oil pan is automatically emptied and replaced with new oil.

[0121] In another embodiment, it is considered that it is not accurate enough to judge whether to retain the reused oil only based on whether the available time of the mixed oil is greater than the preset time threshold. Whenever the control center outputs an oil change or oil replenishment instruction, the time of the output is recorded as the grease update time. The control center calculates the time length between the time distance corresponding to the grease information and the previous grease update time as the usage time of the reused oil, and adds the available time of the mixed oil to the usage time of the reused oil to obtain the total reuse time of the reuse scheme of storing the reused oil at this time and reusing the reused oil. The reused oil is a standard oil volume before use, and reaches the remaining oil volume after use. When reused, the replenishment oil volume is added to reach the standard oil volume again. Therefore, the total reused oil volume of the reuse scheme is the replenishment oil volume plus the standard oil volume. The total reused oil volume is then divided by the total reused usage time to obtain the reused oil consumption per unit time of the reuse scheme.

[0122] In the scheme of draining the reused oil and directly replacing it with new oil, because the amount of the new oil replaced is the standard amount of oil, the total amount of oil change is equal to the standard amount of oil plus the standard amount of oil. The control center can calculate the time required for each grease parameter corresponding to the new oil to reach the parameter threshold according to the preset initial parameter value corresponding to the oil quality parameter of the new oil, and the parameter value change rate, and select the minimum time as the available time of the new oil from the calculated time, and then add the available time of the new oil to the use time of the reused oil to obtain the total use time of the oil change scheme. Finally, the total amount of oil change obtained is divided by the total use time of the oil change to obtain the oil consumption per unit time of the oil change scheme. The oil consumption per unit time of reuse is compared with the oil consumption per unit time of oil change. If the oil consumption per unit time of oil change is greater than the oil consumption per unit time of reuse, it means that compared with directly changing the oil, the solution of using reused oil and then adding part of new oil is more fuel-efficient. In this case, a reused oil storage instruction is output to the frying furnace body to use the reused oil again; otherwise, an oil change instruction is directly output to drain the reused oil and replace it with new oil.

[0123] In another embodiment, considering that some edible oils used for processing are initially solid, the edible oils need to be melted. After the user puts the solid edible oil into the oil pan, the user outputs a melting oil request to the control center through the display screen, and the melting oil request includes the name of the oil. The control center queries the melting oil temperature corresponding to the oil name in the melting oil request in the preset oil information database, and then outputs the melting oil instruction, and the melting oil instruction includes the queried melting oil temperature. The oil information database stores the melting oil temperature, melting temperature, and boiling temperature in association with the oil name.

[0124] The control center obtains the oil level information sent by the liquid level detection terminal, and retrieves the historical oil level information sent by the liquid level detection terminal within the preset time range. If the oil level in the historical oil level information shows an upward or downward trend, a reminder of oil melting is output through the display screen. When the liquid level detection terminal measures the height of the liquid oil in the melting process, the oil level of the liquid oil increases as it melts, indicating that the grease is still melting; if the position of the liquid level detection terminal measures the temperature of the solid oil in the melting process, the height of the solid oil decreases as it melts, making the liquid level detection terminal suitable for different situations. The control center calculates the variance of the oil level obtained within the preset time range. If the obtained variance is within the error threshold, it means that the oil level has stabilized, that is, the grease has been completely melted. At this time, the melting completion information is output through the display screen, thereby realizing automatic oil melting.

[0125] In the above automatic control method for food processing, each time a process is completed, the control center controls the oil quality detector to detect the oil quality of the oil in the oil pan, automatically discharges unqualified oil, measures the liquid level of qualified oil, and automatically replenishes the oil if the liquid level is too low; when the control center detects that the taste information of the next food to be processed has changed, the oil can be automatically changed. If the oil in the oil pan can still be used, the oil will be stored, and after the oil in the oil pan is emptied, new edible oil will be added; if it cannot be used, the oil in the oil pan will be drained and replenished. When the edible oil in the oil pan can be stored for reuse, the control center can determine the solution that consumes less oil through calculation, thereby reducing costs.
