Description

Technical Field

[0001] This invention relates to the field of intelligent food cooking equipment technology, and in particular to a continuous egg frying machine and its control method that can provide real-time feedback and control of egg quality. Background Technology

[0002] In the field of Chinese cuisine, dishes like scrambled eggs with tomatoes, scrambled eggs with green peppers, and fried rice all rely on a crucial step—frying eggs. Traditional home-style egg-frying methods have low output, only enough to feed a few people. In current group meals, student meals, and restaurant catering, frying eggs is mostly done industrially, using planetary or drum woks. While these methods can meet large-scale consumer demand, the specific heat capacity of egg liquid is about 3 / 4 that of water, and protein denaturation requires around 70 degrees Celsius. However, due to the rapid denaturation of eggs and the significant differences in heat transfer coefficients with increasing temperature, industrially used planetary or drum woks suffer from large localized accumulations of egg liquid, uneven heat and mass transfer, and asynchronous protein maturation. When a large amount of egg liquid comes into contact with the wok, the large temperature differences between different areas often result in the bottom of the egg cooking first, while other parts remain liquid. This commonly leads to three major problems: uneven cooking, different tastes, and different textures within the same wok, severely hindering the industrial production of Chinese egg dishes.

[0003] The key technology to be mastered in the industrialized continuous production of scrambled eggs is the precise control of multiple parameters, including precise control of the heat source, adjustment of the egg cooking time and speed, establishment of the relationship between cooking temperature, egg liquid flow rate and heat transfer effect of the heat source, and adjustment of online parameters based on egg quality. Traditional industrial production uses coarse control methods and strategies, mainly relying on time and temperature for control, without any adaptive adjustment of parameters or feedback functions based on egg quality. As a result, the quality of the scrambled eggs cannot be precisely controlled, including quality parameters such as the shape, color, texture and moisture content of the egg pieces.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0057] like Figure 1 As shown, the continuous egg frying machine with real-time feedback control of egg block quality according to the first aspect of the present invention includes a sample power drive and transmission module 04, a sample and auxiliary material addition module 03, a sample premixing module 05, a heat source module 06, a sample preforming module 07, a sample output module 08, a sample quality online detection module 09, and a control module.

[0058] Among them, the sample power drive and transmission module 04 is used to provide power for the continuous transport of the sample in the target direction.

[0059] The sample and auxiliary material addition module 03 and the sample premixing module 05 are interconnected. The sample and auxiliary material addition module 03 is used to continuously add liquid egg liquid sample into the sample premixing module 05.

[0060] The sample preforming module 07 is connected to the sample premixing module 05 and is used to achieve the thermoforming and quality formation of the target shape egg block, and the heat source module 06 is set opposite to the sample preforming module and is used to achieve the thermal coagulation of the liquid egg liquid.

[0061] The sample output module 08 is connected to the sample pre-forming module to output egg pieces to the target area. The online sample quality detection module 09 is installed on the outside of the sample output module 08 and is used to detect the quality of the egg pieces.

[0062] The control module is connected to the sample power drive and transmission module 04, the sample and auxiliary material addition module 03, the heat source module 06, and the sample quality online detection module 09, respectively.

[0063] According to an embodiment of the present invention, a continuous egg frying machine capable of high-throughput continuous egg frying operates as follows: The heat source module 06 first turns on for preheating, and the sample and auxiliary material adding module 03 continuously adds egg liquid to the sample premixing module 05. Under the heating of the heat source module 06, the product is shaped in the sample preforming module 07 and finally transmitted to the sample output module 08. At the same time, the online sample quality detection module 09 measures the output product quality indicators in real time. After analysis and processing, the results are transmitted to the control module. The control module adjusts the precise control of the parameters of each front-end module to ensure the accurate output of product quality and shape.

[0064] In the field of Chinese cuisine, dishes like scrambled eggs with tomatoes, scrambled eggs with green peppers, and fried rice all rely on a crucial step—frying eggs. Traditional home-style egg-frying methods have low output, only enough to feed a few people. In current group meals, student meals, and restaurant catering, frying eggs is mostly done industrially, using planetary or drum woks.

When a large amount of egg liquid comes into contact with the wok, the large temperature differences between different areas often result in the bottom of the egg cooking first, while other parts remain liquid. This commonly leads to three major problems: uneven cooking, different tastes, and different textures within the same wok, severely hindering the industrial production of Chinese egg dishes.

[0065] The key technology to be mastered in the industrialized continuous production of scrambled eggs is the precise control of multiple parameters, including precise control of the heat source, adjustment of the egg cooking time and speed, establishment of the relationship between cooking temperature, egg liquid flow rate and heat transfer effect of the heat source, and adjustment of online parameters based on egg quality. Traditional industrial production uses coarse control methods and strategies, mainly relying on time and temperature for control, without any adaptive adjustment of parameters or feedback functions based on egg quality. As a result, the quality of the scrambled eggs cannot be precisely controlled, including quality parameters such as the shape, color, texture and moisture content of the egg pieces.

[0066] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention proposes a continuous egg frying machine that can adjust the quality of egg pieces in real time. The continuous egg frying machine can realize real-time monitoring of the quality of egg pieces by setting an online sample quality detection module 09, and can make precise adjustments to the working parameters of the continuous egg frying machine based on the detection results of the egg piece quality. Thus, it realizes functions such as adaptive adjustment of parameters and feedback according to the quality of egg pieces, and the quality of the fried eggs can be precisely controlled.

[0067] like Figure 4 As shown, according to some embodiments of the present invention, the online sample quality detection module 09 includes a sampling module and an online detection platform.

[0068] The sampling module is connected to the sample output module 08 and is set opposite to the online detection platform. The sampling module is used to take samples from the sample output module 08 and move the sampled samples to the sample detection area 241 of the online detection platform.

[0069] The online detection platform includes, from top to bottom, a control signal driving module 21, a spectrum signal acquisition module 22, a spectrum light source and signal acquisition sensor integrated module 23, a high-transmittance glass group 24, and a reference plate 25. The high-transmittance glass group 24 defines the sample detection area 241.

[0070] like Figure 4 As shown, according to some embodiments of the present invention, the integrated module 23 for the spectrum light source and the signal acquisition sensor is cylindrical and includes an ultra-weak light emission laser light source 233, an image illumination light source 234, an ultra-weak light emission signal acquisition sensor 232, and an image acquisition sensor 231.

[0071] Within the integrated module 23 for the image light source and signal acquisition sensor, several ultra-weak light-emitting laser light sources 233 and several image illumination light sources 234 are evenly distributed around the circumference; in the direction towards the center of the circle, ultra-weak light-emitting signal acquisition sensor 232 and ultra-weak light-emitting laser light sources 233 are arranged adjacent to each other and correspond one-to-one; image acquisition sensor 231 is located at the center of the circle.

[0072] like Figure 1 As shown, according to some embodiments of the present invention, the control module includes a controller 02 and a host computer 01 that are interconnected.

[0073] The controller 02 is used to drive the power and communicate the signals of each module, and to control the sample delivery speed, the heating speed of the heat source, the transmission of online quality detection data signals, and the transmission of parameter adjustment feedback signals. The host computer 01 is used to process and analyze the data of sample driving parameters, heat source module parameters, egg liquid flow rate and sample addition amount, and online egg quality detection signals, and to display the quality parameter results in real time.

[0074] The following describes a control method for a continuous egg frying machine with real-time feedback regulation of egg quality according to a second aspect embodiment of the present invention, with reference to the accompanying drawings. This control method is based on the structure of the continuous egg frying machine described above, which enables high-throughput continuous egg frying.

[0075] like Figure 5 and Figure 6 As shown, the control method of the continuous egg frying machine that can adjust the quality of egg pieces in real time according to an embodiment of the present invention includes:

[0076] Step S1: Obtain the initial setting parameters of the continuous egg frying machine, and start the continuous egg frying machine according to the initial setting parameters to start frying eggs;

[0077] Step S2: Obtain the output information of the egg pieces, and adjust the working parameters of the continuous egg frying machine according to the output information of the egg pieces.

[0078] According to the control method of the continuous egg frying machine with real-time feedback control of egg quality according to the embodiments of the present invention, by setting up an online sample quality detection module 09, the quality of egg pieces can be monitored in real time, and the working parameters of the continuous egg frying machine can be precisely adjusted based on the detection results of egg piece quality. Thus, the functions of adaptive parameter adjustment and feedback based on egg piece quality are realized, and the quality of the fried eggs can be precisely controlled.

[0079] The production information of the aforementioned egg pieces includes, but is not limited to, the volume and internal quality information of the egg pieces. The internal quality information refers to information such as the moisture content, carbonyl content, microstructure changes, and texture of the egg pieces.

[0080] According to some embodiments of the present invention, the steps of obtaining output information of the produced egg pieces and adjusting the operating parameters of the continuous scrambled egg machine based on the output information of the produced egg pieces specifically include:

[0081] Obtain the actual volume of the produced egg block, as well as the preset target egg block volume;

[0082] The difference between the actual output egg block volume and the set target egg block volume is compared, and the working parameters of the continuous egg frying machine are adjusted according to the first data model between the egg block volume and the working parameters stored in the continuous egg frying machine, until the actual egg block volume reaches the set target egg block volume.

[0083] Furthermore, the steps for establishing the first data model include:

[0084] Obtain the flow rate V of the egg liquid delivered to the sample premixing module 05. 蛋液垂直输送 The sample power drive and transmission module 04 applies a driving force F to the egg liquid in the vertical direction. 驱动力 The height KV of the horizontally extending pipe inside the sample preforming module 07, and the length AD of the heat source module 06 in the horizontal transmission direction of the egg liquid.

[0085] Based on egg liquid flow rate V 蛋液垂直输送 Driving force F 驱动力 The volume V of the egg block is established by using the height KV and the length of action AD. 出品目标 Driving force F 驱动力 and egg liquid flow rate V 蛋液垂直输送 The first data model between them.

[0086] For example, the steps to establish the first data model are as follows:

[0087] First, define a few parameters: the flow rate of egg liquid in the egg liquid delivery pipe is defined as V. 蛋液垂直输送 (ml / min), the driving force applied by the air-blowing power source to the vertical egg liquid is F. 驱动力 (N), the heat transfer capacity of heat source module 06 is C. 传热能力 (KJ / s), the height of the horizontal transmission pipe for egg liquid is KV, and the length of the heat source module 06 in the horizontal transmission direction of egg liquid is AD.

[0088] Before starting operation, the air-blowing drive source initializes the airflow within the pipeline, blowing away impurities or residual substances. Then, the heat source module 06 begins preheating and maintains a constant temperature after reaching the set value. During actual operation, the air-blowing drive force F... 驱动力 (N), Egg liquid flow rate V 蛋液垂直输送 (ml / min), Heat transfer capacity of heat source module 06 C 传热能力 The parameters such as (KJ / s), the height of the horizontal transmission pipe for egg liquid KV, and the length AD of the heat source module 06 in the horizontal transmission direction of egg liquid determine the separation state of the egg liquid when it is output to the outlet of the heat source module 06, that is, the shape, mass and volume of the egg pieces.

[0089] After the egg liquid flows out of the pipe, it is subjected to its own weight G and the air-driven force F. 驱动力Under the combined influence of (N), there is both free fall and horizontal motion. The maximum time (MAX(T)) for the egg liquid to fall to the bottom is... 自由落体 It satisfies the basic laws of physics and conforms to formula (1).

[0090]

[0091] To ensure that the egg liquid completes thermal coagulation and separation under the action of heat source module 06 after flowing out of the pipe, the heat transfer capacity of heat source module 06 is C. 传热能力 (KJ / s) needs to satisfy the condition MAX(T) at maximum time. 自由落体 Inside, heat is transferred to the egg mixture to solidify it, while simultaneously, driven by an airflow force F... 驱动力 (N), and gravity and surface tension of egg liquid F 表面张力 To separate the egg pieces, the driving force needs to overcome the surface tension of the upper and lower sections (e.g., ...). Figure 3 Finally, the solidified egg pieces appear in different sizes and shapes, such as... Figure 2 As shown. The limiting case is when the egg liquid reaches MAX(T) 自由落体 When the heat source module 06 is in the middle, thermal solidification and separation are completed. The minimum heating length AD required by the heat source module 06 at this time can be obtained according to formula (2).

[0092]

[0093] In reality, under the action of external forces, the angle α is close to 0° and changes very little, so AD can be approximated as:

[0094]

[0095] F 驱动力 (N) can be precisely controlled by an air-blowing drive source. The surface tension is related to the cross section MNPQ formed by the egg liquid at different flow rates, satisfying formula (4).

[0096]

[0097] In the above formula (4), σ is the surface tension coefficient of the egg liquid (N / cm), PQ is the diameter of the cross-sectional circle, L is the length of the cross-section at a certain point along the horizontal movement direction of the egg liquid, and PQ is related to the flow rate of the egg liquid. Under different flow rates, due to the Rayleigh-Plateau instability of the liquid, it will form as shown in the figure under its own gravity. Figure 2 The continuous ellipsoidal shape in the model has a cross-section that is approximately circular in the vertical direction, i.e., MNPQ, as shown in the example. Figure 3 As shown.

[0098] At different egg liquid flow rates V 蛋液垂直输送Under the condition of (ml / min), when the egg liquid flows out to the same height H, the volume and cross-section of the ellipsoid are different, and its cross-sectional area satisfies formula (5).

[0099]

[0100] Based on the above analysis, with the fixed transmission pipe cross-sectional diameter KV, the length AD of heat source module 06, and the heat transfer capacity C of heat source module 06... 传热能力 Under the condition of (KJ / s), at this time, MAX(T) 自由落体 The formula (3) is also fixed. If we want to produce smaller egg pieces, we can obtain F according to formula (3). 驱动力 (N) and F 表面张力 The relationship between them, and according to formulas (4) and (5), F 表面张力 And the flow rate of egg liquid V 蛋液垂直输送 (ml / min) is relevant, therefore the egg liquid flow rate V can be established. 蛋液垂直输送 (ml / min), F 驱动力 The relationship between (N) is established, and then the correlation between these two parameters and the required output egg block size is established.

[0101] For example, at a smaller egg liquid flow rate V 蛋液垂直输送 Under the condition of (ml / min), because the circular cross-section that generates the surface tension of the egg liquid becomes smaller, the volume of the egg liquid formed is smaller, because the surface tension F is reduced. 表面张力 Given the same horizontal transport distance AD, to achieve a larger egg block output, F can be reduced. 驱动力 (N), then in MAX(T) 自由落体 During this time, smaller egg pieces are not completely separated, and some small egg pieces that are connected together solidify into larger egg pieces. This occurs within the heat transfer capacity C of the heat source module 06. 传热能力 At a flow rate of (KJ / s), the egg liquid solidifies into larger chunks. To obtain egg chunks of the same volume as at a lower flow rate, a higher egg liquid flow rate V is used. 蛋液垂直输送 Under the condition of (ml / min), because the circular cross-section that generates the surface tension of the egg liquid becomes larger, the volume of the egg liquid formed is smaller, which in turn increases the surface tension F. 表面张力 Given the requirement of the same horizontal transport distance AD, under this adjustment, to achieve an output of egg blocks of the same volume as a smaller flow rate, F can be increased. 驱动力 (N), then before reaching MAX(T) 自由落体 Over time, the egg pieces have completely separated, with some larger pieces breaking down into smaller ones. The heat transfer capacity of heat source module 06 is C. 传热能力 (KJ / s) coagulates into a block, forming a relatively small egg liquid flow rate V 蛋液垂直输送 Similar egg block output under (ml / min) conditions.

[0102] When smaller egg pieces are needed, regardless of the flow rate, F can be increased. 驱动力 (N), then MAX(T) has not been reached. 自由落体 At that time, the egg pieces had already separated, and the heat transfer capacity of the heat source module 06 was C. 传热能力 When the concentration of KJ / s is reduced, the mixture solidifies into small blocks, producing relatively small egg-shaped pieces.

[0103] When larger egg blocks are needed, regardless of the flow rate, F can be reduced. 驱动力 (N), then to reach MAX(T) 自由落体 At that time, the egg pieces were not completely separated, and the heat transfer capacity of the heat source module 06 was C. 传热能力 It can solidify into blocks at (KJ / s) and can output larger egg-shaped blocks.

[0104] Let the required volume of egg liquid be V. 出品目标 At fixed pipe heights KV and V 蛋液垂直输送 Under the condition of (ml / min), the total amount of egg liquid flowing out in a certain time interval t exactly fills the pipe in the vertical direction of the pipe height KV. At this time, t is MAX(T). 自由落体 ), then V 蛋液总量(t) =V 蛋液垂直输送 *MAX(T 自由落体 At this point, the total egg liquid volume can be divided into n equal parts, satisfying formula (6).

[0105]

[0106] The required F at this time 驱动力 (N) is the sum of the forces acting on the n individual target egg blocks, satisfying formula (7).

[0107] F 驱动力 (N)=n*F 驱动力 ( 单个目标蛋块 (7)

[0108] Under the condition that the horizontal transmission distance AD ​​is fixed, F 驱动力(单个目标蛋块) It satisfies formula (8).

[0109]

[0110] F 表面张力 It satisfies formula (4) and approximately satisfies formula (9).

[0111]

[0112] Next, calculate the diameter of the target egg block cross-section. Combined with equation (4), the surface tension can be obtained. Then, F can be obtained according to equations (8), (6), and (9). 驱动力 ( 单个目标蛋块), which satisfies formula (10).

[0113]

[0114] Then, the total driving force F is obtained according to formulas (6) and (7). 驱动力 (N) and V 出品目标 The relationship between them satisfies formula (11):

[0115]

[0116] In the above formula (11), KV, AD, MAX(T) 自由落体 Since σ and σ are both known, F was established based on this formula. 驱动力(N) With V 出品目标 The inherent relationship between them can be used to achieve precise control over egg blocks of different sizes as needed.

[0117] According to some embodiments of the present invention, the step of establishing the first data model further includes:

[0118] In a continuous egg frying machine, various different egg liquid flow rates V can be set. 蛋液垂直输送 and driving force F 驱动力 By adjusting the parameters, we can obtain egg pieces of various sizes.

[0119] Egg block samples of different sizes are obtained using the sample sampling module 11 and transferred to the sample detection area 241;

[0120] The control signal driving module 21 drives the image illumination light source 234 to illuminate the egg block sample, and acquires image information of egg blocks of different sizes based on the image acquisition sensor 231;

[0121] The control image signal acquisition module 22 transmits the egg block image information to the host computer 01 for analysis, and uses image recognition and segmentation algorithms to establish an image signal evaluation model for the shape recognition of different egg block volumes;

[0122] The first data model is modified based on the shape recognition model.

[0123] In this way, by correcting the first data model based on the actual detection results, the first data model can be made more in line with the current use scenario of the continuous egg frying machine, thus ensuring the accuracy of the control logic within the continuous egg frying machine.

[0124] According to some embodiments of the present invention, the steps of obtaining output information of the produced egg pieces and adjusting the operating parameters of the continuous scrambled egg machine based on the output information of the produced egg pieces specifically include:

[0125] Obtain the preset internal quality and, based on the test results of the sample quality online detection module 09, obtain the actual internal quality of the finished egg pieces;

[0126] The difference between the actual internal quality and the set internal quality is compared, and the working parameters of the continuous egg frying machine are adjusted based on the second data model between the internal quality of the egg pieces stored in the machine and the working parameters, until the actual internal quality reaches the set internal quality.

[0127] Furthermore, the steps for establishing the second data model include:

[0128] By adjusting various different egg liquid flow rates V 蛋液垂直输送 Driving force F 驱动力 and the heat transfer capacity C of the heat source module 传热能力 By adjusting the parameters, we can obtain egg pieces of various sizes.

[0129] The control signal driving module 21 drives the ultra-weak light emission laser source to irradiate the egg block sample, obtains the ultra-weak light emission spectrum signal corresponding to the egg block sample, and uses the white reference correction signal to obtain the effective signal;

[0130] The internal quality information of egg block samples of different sizes was obtained by physicochemical determination methods. The internal quality includes, but is not limited to, moisture content, carbonyl content, microstructure changes and texture.

[0131] The control spectrum signal acquisition module 22 transmits the internal quality information to the host computer 01 for analysis, and uses 1stOpt numerical processing software to solve for the optimal optical parameters by combining the least squares algorithm and the general global optimization algorithm. The optimal optical parameters include, but are not limited to, decay time, initial slope, self-emitting electron intensity, total light intensity and average light intensity.

[0132] The optimal decay kinetics of ultra-weak luminescence of internal quality parameters of egg blocks after heat treatment were analyzed using the optimal optical parameters.

[0133] A second data model was established using modeling algorithms such as multiple linear regression and partial least squares. The second data model is an evaluation model of the internal quality of egg blocks based on ultra-weak emission spectrum.

[0134] The following describes a specific embodiment of the control method of the present invention in implementing step S2, which involves "obtaining the output information of the egg pieces and adjusting the working parameters of the continuous frying machine based on the output information of the egg pieces".

[0135] First, an egg block shape and size recognition model based on graphic information is established, and the first data model is generated.

[0136] Specifically, by setting various different egg liquid flow rates V 蛋液垂直输送and driving force F 驱动力 The parameters are used to obtain egg pieces of various sizes. When the egg pieces reach the online detection platform area, the sample sampling module 11 obtains egg piece samples of different sizes (as shown in Table 1). After passing through the sample translation channel 12, they reach the sample detection area 241. The control signal drive module 21 drives the image illumination light source 234 to illuminate the egg piece samples. The image acquisition sensor 231 acquires the image information of egg pieces of different sizes. The image signal acquisition module 22 transmits the information to the host computer 01 for analysis. The image recognition and segmentation algorithms such as edge detection and convolutional neural networks are used to establish an image signal evaluation model for the shape recognition of different egg piece volumes and colors. This provides a basis for adjusting the flow rate parameters and driving force parameters of the front-end continuous egg frying machine based on the egg piece volume.

[0137] Table 1

[0138]

[0139] Secondly, an evaluation model for the internal quality of egg pieces based on ultra-weak emission spectrum was established, which is also known as the second data model.

[0140] Specifically, by adjusting the different egg liquid delivery flow rates V 蛋液垂直输送 F 驱动力 Heat transfer capacity C of the heat source module 传热能力 The parameters were obtained by using the same sample as the image recognition model to acquire egg block samples. The control signal drive module 21 was used to drive the ultra-weak emission laser source 233 to irradiate the egg block samples, and the corresponding ultra-weak emission spectrum signal of the egg block samples was acquired. The effective signal was obtained by using the white reference correction signal. At the same time, the internal quality information such as moisture content, carbonyl content, microstructure changes, and texture of different egg block volumes were obtained by using physicochemical measurement methods (Table 2). The spectrum signal acquisition module 22 was used to transmit the data to the host computer 01 for analysis. The 1stOpt numerical processing software was used to solve the optimal optical parameters, including decay time, initial slope, self-emitting electron intensity, total light intensity, and average light intensity, by combining the least squares algorithm and the general global optimization algorithm. These parameters were used to analyze the optimal decay kinetic change law of ultra-weak emission of the internal quality parameters of the egg block after heat processing. A quality evaluation model for different egg pieces, including moisture content, carbonyl content, microstructure changes, and texture, was established using modeling algorithms such as multiple linear regression and partial least squares. This model provides a basis for adjusting the flow rate, driving force, and heat transfer capacity parameters of the front-end continuous egg frying machine based on the size of the egg pieces.

[0141] Table 2

[0142]

[0143] Finally, a model relationship was established between the ultra-weak emission spectrum, image, and quality parameters such as egg block size, moisture content, carbonyl content, microstructure changes, texture, and color, and the results were transmitted to the host computer. During actual adjustment, the egg liquid flow rate V at the front end was adjusted according to the desired results. 蛋液垂直输送 (ml / min), F 驱动力 (N) Size, heat transfer capacity of heat source module C 传热能力 The quality of the output egg blocks is controlled by (KJ / s), and the upper computer 01 outputs a signal to the controller 02 to achieve precise control.

[0144] For example, when frying eggs, given the egg liquid flow rate, a predictive model for the egg pieces and their internal quality under different driving forces at this flow rate has been established and embedded in the computer. If a larger egg piece is desired than the one currently being obtained from the outlet, the driving force can be adjusted according to this model to achieve size regulation. Image recognition results are used for real-time feedback. If this cannot be achieved under the current flow rate model, the model automatically switches to a model with a larger flow rate, iterating and converging until the optimal result is obtained. Similarly, if it is necessary to adjust the flow rate, driving force, and heat transfer capacity based on internal quality, the model at a specific flow rate is iteratively converged. By switching models, parameters are adaptively adjusted, and the results are obtained in real-time using ultra-weak emission spectroscopy, continuously feeding back to the front end to ultimately obtain the optimal adjustment result.

[0145] The following describes a specific embodiment of the control method of the continuous egg frying machine of the present invention, which can adjust the quality of egg pieces in real time with reference to the accompanying drawings.

[0146] like Figure 7 As shown, firstly, the parameters such as pipe size, heating pipe length, and online detection module position information of the continuous egg frying machine are initialized. The overall control signal is set, each module is powered on, and the initial values ​​such as heating temperature and flow rate of each module are set. The information of each parameter is obtained in real time using sensor information such as temperature sensor and flow meter.

[0147] Next, it is determined whether the various working parameters in the continuous egg frying machine have reached the initial set values. If they have, the egg frying program is started, the egg liquid is injected into the continuous egg frying machine, the driving force starts to work, and the required egg block volume and internal quality parameters are set in the host computer 01. Furthermore, based on the required egg block volume and internal quality, the program automatically adjusts the flow rate, driving force and heating capacity parameters using the graphic recognition egg block volume program and the ultra-weak emission spectrum evaluation module.

[0148] Subsequently, the online detection module begins to collect internal and external quality information of the scrambled eggs and uploads it to the host computer 01. During the above process, the host computer 01 stores prediction models of egg block volume and color based on graphic information, as well as internal prediction models of egg block microstructure and moisture content based on ultra-weak emission spectrum.

[0149] Furthermore, it is determined whether the matching degree between the scrambled egg result and the preset result meets the requirements. If it does, the detection result is displayed on the host computer 01 and the scrambled egg result is output. If it does not meet the requirements, the working parameters of the continuous scrambled egg machine are readjusted until the matching degree between the scrambled egg result and the preset result meets the requirements.

[0150] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
