Description

Technical Field

[0001] This application relates to the field of milk production technology, and in particular to online standardization methods and systems for dairy products in intelligent modular factories. Background Technology

[0002] In the dairy industry, with the continuous upgrading of consumption patterns, consumers' demand for personalized and high-quality dairy products is surging. Different brands of dairy products exhibit diverse formulation requirements for core physicochemical indicators such as protein content. However, the protein content of raw milk is naturally subject to significant and uncontrollable fluctuations due to the coupled influence of multiple factors, including cow breed, feeding season, forage quality, and pasture management level. This makes it difficult for raw milk to directly meet the precise formulation requirements of end products. Therefore, standardizing raw milk has become an indispensable and crucial step in the dairy product manufacturing process.

[0003] Currently, the standardized raw milk processing solutions commonly used in traditional dairy factories involve first separating the fat and protein from the raw milk, and then adding the separated components back into the raw milk through online blending according to the preset requirements of the finished milk, in order to meet the standards. However, this traditional method has inherent drawbacks: on the one hand, it requires a separate ingredient preparation workshop and relies on specialized equipment such as feeding equipment or triple-effect concentrators for collaborative operation, resulting in a complex and cumbersome processing flow; on the other hand, its processing efficiency is relatively low, and the large investment in equipment and the large space required lead to high overall production costs.

[0004] The emergence of new intelligent modular dairy processing plants represents a new direction for the dairy industry. This production model is characterized by high efficiency, low cost, and minimal space requirements. However, the complex processes, low efficiency, and high space requirements of traditional standardized raw milk processing methods are significantly incompatible with the core demands of this new production model and cannot meet the actual production needs of these modular plants. Therefore, there is an urgent need for a standardized raw milk processing technology adapted to these new intelligent modular plants to address the shortcomings of existing technologies and promote the intelligent and efficient development of the dairy production industry. Summary of the Invention

[0005] Therefore, it is necessary to address the problem that the traditional raw milk standardization processing methods in factories cannot be adapted to the production mode of new intelligent dairy modular factories, and to provide an online standardization method and system for dairy products applied to intelligent modular factories.

[0006] A method for online standardization of dairy products applied in intelligent modular factories includes the following steps:

[0007] The component content of raw milk in the raw milk conveying pipeline is detected online; based on the detected component content of the raw milk and the target index, the concentration control parameters for controlling membrane concentration are calculated; based on the concentration control parameters, the raw milk components are standardized through membrane concentration.

[0008] In one embodiment, the concentration control parameter includes a concentration ratio value; when the concentration ratio value is greater than a preset value, membrane concentration is activated and the raw milk is concentrated according to the concentration ratio value; otherwise, membrane concentration is not activated.

[0009] In one embodiment, the step of calculating the concentration control parameter includes: comparing the detected component content of raw milk with the target index, and determining whether concentration is required based on the comparison result; if concentration is required, calculating the concentration ratio value based on the component content and the target index, and using it as the concentration control parameter; if concentration is not required, using a preset value as the concentration control parameter.

[0010] In one embodiment, the component content of the raw milk includes fat / protein content, and the concentration ratio is the ratio of the target index to the fat / protein content of the raw milk; when the concentration ratio is greater than 1, membrane concentration is activated to standardize the raw milk.

[0011] A smart modular dairy processing plant online standardization system includes: an online detection device installed on a raw milk conveying pipeline and configured to detect the component content of the raw milk in the pipeline; a membrane concentration device located downstream of the online detection device and connected to the raw milk conveying pipeline, the membrane concentration device being configured to concentrate the raw milk according to concentration control parameters to achieve standardization; and a main control device connected to the online detection device and the membrane concentration device, configured to calculate the concentration control parameters based on the detected component content of the raw milk and target indicators, and control the membrane concentration device according to the parameters.

[0012] In one embodiment, the main control device includes an information receiving module, an information analysis module, and an information conversion module electrically connected to each other; wherein, the information receiving module is configured to receive the component content of raw milk obtained by the online detection device, the information analysis module is configured to analyze the component content and target indicators of raw milk and determine concentration control parameters, and the information transmission module is configured to transmit the concentration control parameters to the membrane concentration device.

[0013] In one embodiment, the main control device further includes a control module electrically connected to the information analysis module and configured to control the output of raw milk to the membrane concentration device when the information analysis module determines that the concentration control parameter is greater than 1, and to control the output of raw milk to the next processing device when the information analysis module determines that the concentration control parameter is less than or equal to 1, wherein the concentration control parameter is the ratio between the target index and the component content of the raw milk.

[0014] In one embodiment, the membrane concentration apparatus includes a concentration unit, wherein the concentration unit is provided with an RO membrane for concentrating raw milk.

[0015] In one embodiment, the membrane concentration apparatus further includes a clear liquid collection tank, which is connected to the concentration unit and configured to store the clear liquid output from the membrane concentration apparatus.

[0016] In one embodiment, the membrane concentration apparatus further includes a cleaning unit connected to the concentration unit and configured to clean the concentration unit and the delivery pipeline.

[0017] The aforementioned online standardization method and system for dairy products applied in intelligent modular factories detects the component content of raw milk in the raw milk conveying pipeline online and automatically adjusts the membrane concentration ratio based on the detected component content and target indicators through a membrane concentration device. The two work together to achieve real-time online standardization of raw milk proteins. This eliminates the need for offline sampling and waiting for test results before standardization. Compared with traditional standardization methods, this not only greatly saves production equipment, but also makes the standardization operation of intelligent modular factories simple and efficient through the entire online process. It is effectively adapted to the new intelligent dairy modular factory production model that requires high efficiency, low cost and limited space. Attached Figure Description

[0033] See Figure 1 One embodiment of this application provides an online standardization system for dairy products applied in a smart modular factory, including an online detection device 1, a membrane concentration device 2, and a main control device 3.

[0034] The online detection device 1 is installed on the raw milk conveying pipeline 11 and is configured to detect the component content of the raw milk in the raw milk conveying pipeline 11. Specifically, in the embodiments of this application, the online detection device 1 is an online protein analyzer, which can detect the component content of the raw milk conveyed through the raw milk conveying pipeline 11 in real time.

[0035] The membrane concentration unit 2 is located downstream of the online detection unit 1 and connected to the raw milk conveying pipeline 11. The membrane concentration unit 2 is configured to concentrate the raw milk according to the concentration control parameters to achieve standardization and obtain the finished milk that meets the formula requirements. Compared with traditional standardization operation methods, the dairy online standardization system of this application can greatly shorten the standardization time, effectively improve the standardization efficiency, and is suitable for just-in-time production mode, ensuring that the raw milk can be produced within 2 hours.

[0036] The main control device 3 is connected to the online detection device 1 and the membrane concentration device 2, and is configured to calculate concentration control parameters based on the detected component content and target indicators of the raw milk, and to control the membrane concentration device to start membrane concentration according to the parameters to match different formulation requirements. Understandably, in the embodiments of this application, the main control device 3 can receive the component content L value information of the raw milk obtained by the online detection device 1, analyze the L value with the target indicator value R of the finished milk required by the formulation, determine whether the raw milk needs to be concentrated, and calculate the concentration ratio N based on the L value and the R value. When concentration is not required, the N value is less than or equal to 1, and the main control device 3 can directly control the raw milk to be output to the next processing device for the next step of processing. When concentration is required, the main control device 3 transmits a concentration ratio greater than 1 to the membrane concentration device 2 and starts the concentration process.

[0037] In summary, the above-mentioned online standardization system for dairy products applied in intelligent modular factories achieves real-time online standardization of raw milk proteins by installing an online detection device 1 for detecting the component content of raw milk on the raw milk conveying pipeline 11, and automatically adjusting the membrane concentration ratio according to the detected component content and target indicators through a membrane concentration device 2. This eliminates the need for offline sampling and waiting for test results. Compared with traditional standardization methods, this system not only greatly saves production equipment, but also makes the standardization operation of intelligent modular factories simple and efficient through the online process. It effectively adapts to the new intelligent dairy modular factory production mode that requires high efficiency, low cost and limited space.

[0038] See Figure 1 and Figure 2 In one embodiment, the main control device includes an information receiving module 31, an information analysis module 32, and an information conversion module 33, which are electrically connected to each other. The information receiving module 31 is configured to receive the component content of raw milk obtained by the online detection device 1; the information analysis module 32 is configured to analyze the component content and target indicators of the raw milk and determine the concentration control parameters; and the information transmission module is configured to transmit the concentration control parameters to the membrane concentration device 2. It is understood that, in the embodiments of the application, the concentration control parameters include a concentration ratio value.

[0039] In addition, the main control device also includes a control module 34, which is electrically connected to the information analysis module 32 and is configured to control the output of raw milk to the membrane concentration device 2 when the information analysis module 32 determines that the concentration ratio value is greater than 1, and to control the output of raw milk to the next processing device when the information analysis module 32 determines that the concentration ratio value is less than or equal to 1, wherein the concentration ratio value is the ratio between the target index and the component content of the raw milk.

[0040] Understandably, in the embodiments of this application, the main control device can be a remote data analysis system connecting the online detection device 1 and the membrane concentration device 2. It is connected to the production system ERP or order system. After receiving the component content L value of the raw milk, it analyzes it against the target indicator R value obtained from the production system ERP or order system to determine whether the raw milk needs to be concentrated. Based on the L and R values, it calculates the concentration ratio N. When concentration is not required, and the concentration ratio N is less than or equal to 1, the control module 34 directly controls the raw milk to be output to the next processing device for the next step. When concentration is required, the control module 34 transmits the calculated concentration ratio N to the membrane concentration device 2.

[0041] For example, this application can first preset a standard library of finished milk protein values ​​according to the dairy product manufacturing industry standards, and set standard values ​​of finished milk protein such as 3.3, 3.6, 4.0, etc. The product order information selects the reference value of finished milk protein based on the data of the finished milk protein value standard library, thereby estimating whether the corresponding smart modular factory meets the requirements of this order. If it does, the target index value R of finished milk is recorded and entered.

[0042] If the component content (L) of the raw milk is less than the target indicator (R), it indicates that the component content of the raw milk does not meet the protein requirements of the finished milk, and the raw milk needs to undergo standard treatment, i.e., membrane concentration device 2 is turned on for membrane concentration to meet the finished milk indicators. Conversely, if the component content (L) of the raw milk is greater than the target indicator (R), it indicates that the component content of the raw milk meets the protein requirements of the finished milk, and standard treatment of the raw milk is not required. Membrane concentration device 2 does not need to be turned on, and the raw milk directly enters the subsequent sterilization process, with membrane concentration device 2 performing bypass treatment. Furthermore, in the embodiments of this application, the concentration ratio N = R / L, and membrane concentration device 2 automatically adjusts the membrane filtration pressure according to this concentration ratio to perform concentration treatment.

[0043] See Figure 1 and Figure 3In one embodiment, the membrane concentration device 2 includes a concentration unit 21, which contains an RO membrane for concentrating raw milk. Specifically, the concentration unit 21 includes a housing, an RO membrane, a concentrated milk output pipe, and a clarified liquid output pipe. The RO membrane is disposed inside the housing. Both the concentrated milk output pipe and the clarified liquid output pipe are connected to the housing. The concentrated milk output pipe is configured to output the concentrated milk obtained after concentration by the RO membrane, and the clarified liquid output pipe is configured to output the clarified liquid obtained after concentration by the RO membrane.

[0044] Furthermore, to further ensure the concentration effect, multiple concentration units 21 are provided in the embodiments of this application. It is understood that by setting multiple concentration units 21, this system allows the remaining concentration units 21 to continue operating normally even when one concentration unit 21 is being cleaned or malfunctioning, without requiring shutdown or production stoppage. In addition, the multiple concentration units 21 can be matched with different concentration ratios of fat and protein specifications to suit different formulations.

[0045] More specifically, in the embodiments of this application, the concentration unit 21 extends along the length direction, so that the raw milk can remain straight in the flow channel inside the outer shell, reducing frictional resistance and pumping energy consumption. Multiple concentration units 21 are arranged in a regular array along the width and height directions, which can significantly improve space utilization without changing the floor space, so as to meet the high-capacity layout requirements in the confined space of the modular factory.

[0046] In one embodiment, the concentration unit 21 is connected to the raw milk conveying pipe 11 via a conveying pipe. The raw milk that has been tested in the raw milk conveying pipe 11 can be conveyed to the concentration unit 21 via the conveying pipe. It can be understood that in the embodiments of this application, the conveying pipes are connected to the concentration unit 21 and the next processing device respectively. When concentration is not required, the raw milk in the raw milk conveying pipe 11 is conveyed to the next processing device for the next step of processing. When concentration is required, the raw milk in the raw milk conveying pipe 11 is conveyed to the membrane concentration device 2 for concentration.

[0047] Furthermore, because the concentration unit 21 itself has transmembrane pressure difference requirements, its inlet needs to maintain a stable pressure. However, the raw milk conveying pipeline 11 at the farm end is usually designed as a gravity or low-head centrifugal pump, and the pressure is insufficient to overcome the concentrated resistance of the subsequent multiple array membrane modules. Therefore, in the embodiments of this application, in order to ensure the conveying effect, a booster pump is provided between the conveying pipeline and the raw milk conveying pipeline 11. The booster pump can effectively increase the pressure, ensuring the rated cross-flow velocity and compensating for the loss of resistance along the way and in local areas. This ensures that the concentration unit 21 can continuously and stably obtain the design flow rate, and avoids concentration polarization or retention rate fluctuations in the internal RO membrane due to low pressure.

[0048] In one embodiment, the membrane concentration apparatus 2 further includes a clarified liquid collection tank 22, which is connected to the concentration unit 21 and configured to store the clarified liquid output from the membrane concentration apparatus 2. Specifically, the clarified liquid collection tank 22 is spaced apart from the concentration unit 21 and is connected to the concentration unit 21 via a clarified liquid output pipe.

[0049] It is understandable that the clarified liquid (permeate) produced during the membrane concentration process still contains lactose, minerals, and water-soluble vitamins. Direct discharge would waste resources and increase COD load. This application addresses this by installing a clarified liquid collection tank, which balances the instantaneous flow difference between concentration and downstream processes, preventing back pressure fluctuations on the permeate side from affecting membrane flux. Furthermore, based on standardization goals, the clarified liquid can be quantitatively recycled back to raw milk or skim milk to rapidly reduce fat and component content, achieving "two-way" standardization. In addition, the recovered clarified liquid can be used for CIP pre-rinsing, lactose crystallization raw materials, or feed formulation, improving total solids utilization and reducing wastewater treatment costs. Therefore, the clarified liquid collection tank is directly connected to the concentration unit 21 and equipped with storage functionality, ensuring process stability and providing a flexible interface for resource recycling.

[0050] In one embodiment, the membrane concentration unit 2 further includes a cleaning unit 23, which is connected to the concentration unit 21 and configured to clean the concentration unit 21 and the delivery pipeline. It is understood that after the membrane concentration unit 21 operates, proteins, fats, and minerals accumulate inside, leading to a decrease in flux and an increase in transmembrane pressure, requiring the membrane performance to be restored within a specified time. By setting up the cleaning unit 23 and connecting it in a closed loop with the concentration unit 21, alkali / acid / cleaning agents with set temperature, concentration, and flow rate can be used to circulate and flush the inside of the concentration unit 21, dissolving and removing the deposited layer, restoring the designed flux. Furthermore, by returning the cleaning solution through the same delivery pipeline, simultaneous sterilization of valves, pumps, pipelines, and other auxiliary equipment can be ensured, avoiding secondary contamination, thereby ensuring continuous and stable system operation, extending membrane life, and meeting food safety requirements.

[0051] In one embodiment, the cleaning unit 23 includes multiple solution tanks, each containing water and a different cleaning agent, to achieve efficient, safe, and low-consumption cleaning. Specifically, each solution tank is connected to the concentration unit 21 via a cleaning pipe and contains water, alkali, acid, and disinfectant, respectively. By including multiple solution tanks containing water, alkali, acid, and disinfectant in the cleaning unit 23, acid and alkali can be stored separately, avoiding cross-reactions, preventing neutralization failure and exothermic risks, and ensuring cleaning effectiveness and operational safety. Furthermore, the heating and proportioning circuits configured in each tank can be set to different temperatures and concentrations according to the membrane material's tolerance conditions, extending membrane life and achieving independent control of concentration and temperature.

[0052] Understandably, when using the cleaning unit 23, residual milk can be rinsed away with clean water first, then protein and fat can be dissolved with alkaline solution, mineral scale can be removed with acid solution, and finally microorganisms can be killed with disinfectant to achieve complete restoration of the membrane surface. One of the solution tanks can serve as a clean water tank to temporarily store the final rinse water for the next pre-rinse, reducing water consumption and wastewater discharge.

[0053] See Figure 1 and Figure 4 In one embodiment, the online detection device includes a flow cell 12 and a detection head 13. The flow cell 12 is embedded in the raw milk conveying pipe 11, and the detection head 13 is mounted on the outer shell of the flow cell and configured to detect the component content of the raw milk flowing in the flow cell, so as to subsequently confirm the concentration.

[0054] Specifically, the flow cell 12 is embedded in the raw milk conveying pipe 11 in the form of a short pipe of the same diameter, maintaining the same flow velocity profile as the main pipe to avoid dead zones and pressure drops. The detection head 13 is set in the transparent observation window of the outer shell of the flow cell 12, which can collect protein characteristic signals in real time using near-infrared absorbance or refractive index. This design ensures that the detection optical path is synchronized and stable with the milk flow rate, eliminating errors caused by bubbles and laminar flow differences, achieving second-level response of component content and no sampling lag, providing real-time and representative full-stream data for subsequent membrane concentration closed-loop adjustment.

[0055] See Figure 1 and Figure 5 The embodiments of this application also provide a method for online standardization of dairy products applied in intelligent modular factories, including the following steps:

[0056] First, the component content of the raw milk in the raw milk conveying pipeline is detected online. Specifically, before detection, the online detection device installed on the raw milk conveying pipeline is calibrated to ensure that the online detection device is functioning properly. Then, the protein content (L value) of the raw milk in the raw milk conveying pipeline is detected online using the online detection device. It is understood that, in the embodiments of this application, the online detection device is an online protein analyzer, which can detect the component content of the raw milk conveyed through the raw milk conveying pipeline in real time, wherein the component content includes the protein content.

[0057] Secondly, based on the detected component content and target indicators of the raw milk, the concentration control parameters used to control membrane concentration are calculated. Specifically, the main control device receives the component content L value information of the raw milk obtained by the online detection device, analyzes the L value with the target indicator value R of the finished milk required by the formula, determines whether the raw milk needs to be concentrated, and calculates the concentration ratio N based on the L value and the R value.

[0058] Finally, based on the concentration control parameters, the raw milk components are standardized through membrane concentration. Specifically, the concentration control parameters include the concentration ratio value, which the membrane concentration unit uses to concentrate the raw milk. That is, when the concentration ratio value is greater than the preset value, the main control unit controls the membrane concentration unit to start membrane concentration and concentrate the raw milk according to the concentration ratio value; conversely, the main control unit controls the membrane concentration unit not to start, thereby obtaining the finished milk that meets the formula requirements. Compared with traditional standardization operation methods, the intelligent modular factory dairy online standardization system of this application can greatly shorten the standardization time, effectively improve the standardization efficiency, and is suitable for just-in-time production mode, ensuring that raw milk production is completed within 2 hours.

[0059] In summary, the online standardization method for dairy products in the intelligent modular factory proposed in this application enables real-time online standardization of raw milk protein by detecting the component content of raw milk in the raw milk conveying pipeline and determining the concentration ratio value in real time based on the detected component content and target indicators. This eliminates the need for offline sampling and waiting for test results. Compared with traditional standardization methods, this method not only greatly saves production equipment, but also makes the standardization operation of the intelligent modular factory simple and efficient through the online process. It effectively adapts to the new intelligent dairy modular factory production mode that requires high efficiency, low cost and limited space.

[0060] In one embodiment, the step of calculating the concentration control parameter includes: comparing the detected component content of the raw milk with the target index, and determining whether concentration is required based on the comparison result. If concentration is required, a concentration ratio value is calculated based on the component content and the target index, and used as the concentration control parameter; if concentration is not required, a preset value is used as the concentration control parameter.

[0061] The raw milk composition includes fat / protein content, and the concentration ratio is the ratio of the target index to the fat / protein content of the raw milk. When the concentration ratio is greater than 1, membrane concentration is initiated to standardize the raw milk. Specifically, the main control unit analyzes the L value and the target index value R of the finished milk required by the formula, and calculates the concentration ratio N based on the L and R values. When N is less than or equal to 1, no concentration is required, and the main control unit can directly control the output of the raw milk to the next processing unit for the next step of processing. When N is greater than 1, concentration is required, and the main control unit transmits the concentration ratio greater than 1 to the membrane concentration unit.

[0062] For example, this application can first preset a standard library of finished milk protein values ​​according to the dairy product manufacturing industry standards, and set standard values ​​of finished milk protein such as 3.3, 3.6, 4.0, etc. The product order information selects the reference value of finished milk protein based on the data of the finished milk protein value standard library, thereby estimating whether the corresponding smart modular factory meets the requirements of this order. If it does, the target index value R of finished milk is recorded and entered.

[0063] If the component content (L value) of the raw milk is less than the target indicator (R value), it indicates that the component content of the raw milk does not meet the protein requirements of the finished milk, and the raw milk needs to undergo standard treatment, i.e., the membrane concentration device needs to be turned on for membrane concentration to meet the finished milk indicators. Conversely, if the component content (L value) of the raw milk is greater than the target indicator (R value), it indicates that the component content of the raw milk meets the protein requirements of the finished milk, and the raw milk does not need to undergo standard treatment. The membrane concentration device does not need to be turned on, and the raw milk directly enters the subsequent sterilization process, with the membrane concentration device 2 bypassing the process.

[0064] In one embodiment, the online standardization method for dairy products in the intelligent modular factory of this application further includes: temporarily storing the clarified liquid obtained after standardization. It is understood that the clarified liquid (permeate) generated during the membrane concentration process still contains lactose, minerals, and water-soluble vitamins. Direct discharge would waste resources and increase COD load. This application uses a clarified liquid collection tank to temporarily store the clarified liquid obtained after concentration, which can balance the instantaneous flow difference between concentration and downstream processes, avoid the impact of back pressure fluctuations on the permeate side on membrane flux, and, according to standardization targets, quantitatively remix the clarified liquid into raw milk or skim milk to quickly reduce fat and component content, achieving "two-way" standardization. Furthermore, the recovered clarified liquid can be used for CIP pre-rinsing, lactose crystallization raw materials, or feed formulation, improving total solids utilization and reducing wastewater treatment costs.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
