Description

Technical Field

[0001] The present invention relates to the technical field of production intelligent control, and in particular to a temperature control method and equipment for yeast culture production. Background Art

[0002] Yeast, as an important microorganism, is widely used in the food, beverage, and pharmaceutical industries. Solid fermentation technology has been widely used in yeast culture due to its superior nutrient conversion efficiency. However, during the solid fermentation process, the metabolism of yeast will generate heat, causing the temperature of the fermented material to continue to rise. Especially in large-scale fermentation, the temperature is likely to exceed the most suitable growth temperature of yeast (generally 25°C to 30°C), resulting in poor fermentation results and even inhibiting yeast growth. Therefore, strict temperature control is required during the production of yeast culture.

[0077] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0078] The present invention provides a temperature control method for yeast culture production, such as Figure 1 As shown, including:

[0079] S1. Monitoring the temperature control basis of multiple production nodes in the yeast culture production site;

[0080] In S1, the production node is a container for containing fermentation materials, and its temperature control basis includes at least: the optimal growth temperature of the fermentation materials in the container at the fermentation stage, the temperature in the container, the ambient temperature outside the container, the future change of the ambient temperature outside the container, the state of the temperature control equipment of the container, etc.;

[0081] S2. Based on the temperature control basis of each production node, decide on the temperature control plan for each production node;

[0082] In S2, the temperature control basis is used as a decision basis to decide the temperature control plan of each production node, and the temperature control plan at least includes: the operation control plan of the temperature control equipment of the container within a certain period of time in the future; specifically, when making a temperature control plan based on the temperature control basis, a large amount of expert temperature control experience related to yeast culture production can be used in advance to train the neural network model until convergence to obtain an artificial intelligence model, and each time a temperature control plan is decided, the artificial intelligence model is used to make a decision;

[0083] S3. Based on the temperature control scheme of each production node, perform corresponding temperature control on each production node.

[0084] In S3, finally, the temperature control scheme is implemented to achieve automated fermentation temperature control at each production node.

[0085] The present application monitors the temperature control basis of multiple production nodes in a yeast culture production site, decides on the temperature control plan for each production node based on the temperature control basis of each production node, and performs corresponding temperature control on each production node based on the temperature control plan for each production node. There is no need for manual temperature control by staff at the yeast culture production site, which reduces labor costs, improves temperature control efficiency, and can perform comprehensive and timely temperature control on yeast culture production sites with larger production scales.

[0086] In one embodiment, the plurality of production nodes comprises at least: a plurality of cylindrical stainless steel barrels;

[0087] Wherein, each cylindrical stainless steel cylinder is provided with fermentation materials;

[0088] Each cylindrical stainless steel cylinder is arranged in a vertical direction, and a preset gap is maintained between adjacent cylindrical stainless steel cylinders to provide air circulation space;

[0089] A temperature control module is provided outside each cylindrical stainless steel cylinder to maintain the temperature of the fermentation material;

[0090] The bottom diameter of each cylindrical stainless steel cylinder is a preset diameter length to ensure uniform temperature distribution of the fermented material.

[0091] In many yeast fermentation processes, in order to obtain specific metabolites, it is usually necessary to maintain an anaerobic environment to prevent aerobic metabolism. Although the traditional turning method can help dissipate heat to a certain extent, it breaks the anaerobic conditions, causing oxygen to enter and affecting product quality. Therefore, how to control the temperature during the fermentation process without destroying the anaerobic environment has become a technical problem that needs to be solved urgently.

[0092] The multiple production nodes of the present invention include multiple cylindrical stainless steel barrels, with a certain gap between the barrels to form multiple fermentation units; the barrel of each fermentation unit contains fermentation materials, and the temperature is adjusted by peripheral temperature control equipment.

[0093] The cylindrical stainless steel barrel is made of high temperature resistant and corrosion resistant stainless steel material to ensure stability in high temperature environments, and the inner wall is smooth to avoid material adhesion. The diameter of the barrel should not be too large to ensure uniform temperature distribution of the fermented material, which can be set in advance.

[0094] The gaps between the cylinders are used to guide cooling airflow or air circulation, thereby achieving material cooling.

[0095] The temperature control module is located on the periphery of the cylindrical stainless steel cylinder. It mainly controls the temperature of the fermentation material through cooling air flow or liquid circulation to ensure that the temperature remains in the range most suitable for yeast growth. The temperature control module can be implemented through components such as fans, heat exchangers and cooling pipes.

[0096] During specific use, the yeast culture medium or other fermentation raw materials are evenly loaded into multiple cylindrical stainless steel cylinders to ensure that the materials are sealed to prevent air from entering; cooling air flow is introduced through the gaps between the cylinders, or the temperature of the fermentation materials is adjusted through external temperature control equipment to ensure that the temperature is controlled within the most suitable range for yeast growth; since the solid fermentation materials are not turned over and a closed design is adopted, oxygen can be effectively prevented from entering, maintaining an anaerobic environment and promoting the production of anaerobic metabolic products.

[0097] In one embodiment, after performing temperature control on each production node accordingly based on the temperature control scheme of each production node in S3, the method further includes:

[0098] S4. Monitor temperature control anomalies at each production node;

[0099] In S4, the temperature control anomaly includes at least: failure of the temperature control equipment, temperature fluctuation or unevenness in the container, etc.;

[0100] S5. Assist multiple managers in the yeast culture production site to handle emergency situations of temperature control anomalies at each production node;

[0101] In S5, the yeast culture production site will be equipped with multiple administrators to handle temperature control anomalies on site. If the temperature control anomalies cannot be handled in time, it may seriously affect the yeast production quality. Therefore, the system collaborates with the administrators online to handle the temperature control anomalies of each production node.

[0102] Wherein, the S5, assisting multiple administrators in the yeast culture production site to handle emergency situations of abnormal temperature control at each production node, includes:

[0103] S51. Push the temperature control anomaly of each production node to each administrator, and activate the joint status tracking library of each administrator;

[0104] In S51, when each administrator receives the pushed temperature control anomaly of each production node, he will independently conduct on-site consultation and start the anomaly handling work; track the work status of all administrators in the anomaly handling work and enter all of them into the joint status tracking library. The work status at least includes: whether the cause of the temperature control anomaly has been determined, whether the impact of the temperature control anomaly on the production node has been evaluated, the measures to handle the temperature control anomaly, whether all the anomaly handling steps and results have been recorded, the current on-site location and the current work progress, etc.;

[0105] S52, based on the joint status tracking library and the auxiliary planning knowledge base of each production node's temperature control anomaly, updating the joint emergency processing auxiliary library of each administrator in real time;

[0106] In S52, the auxiliary planning knowledge base for temperature control anomalies contains a plurality of auxiliary planning knowledge indicating how to assist the administrator in handling temperature control anomalies. The joint status tracking library reflects the working status of each administrator. Therefore, based on the joint status tracking library and the auxiliary planning knowledge base, it is possible to plan in real time how to assist each administrator in handling, that is, update the joint emergency handling auxiliary library, which contains a plan for assisting all managers in joint emergency handling.

[0107] S53. Based on the updated joint emergency processing auxiliary library, assist each administrator to perform emergency processing on the temperature control anomaly of each production node.

[0108] In S53, after the joint emergency processing auxiliary library is updated, it assists each administrator to perform emergency processing on the temperature control anomaly of each production node.

[0109] The embodiment of the present invention monitors the temperature control anomalies of each production node, assists multiple administrators in the yeast culture production site to perform emergency processing on the temperature control anomalies of each production node, improves the efficiency and timeliness of temperature control anomaly processing, and improves the stability of temperature control in yeast culture production. Next, the implementation is carried out in a manner of updating the joint emergency processing auxiliary library in real time and assisting each administrator based on the updated joint emergency processing auxiliary library, ensuring that each administrator continues to receive the most appropriate assistance at the moment, greatly improving the efficiency of assistance. Secondly, a joint status tracking library and an auxiliary planning knowledge base for temperature control anomalies are introduced, and the joint emergency processing auxiliary library is updated in real time based on the two, thereby improving the accuracy of real-time updates of the joint emergency processing auxiliary library.

[0110] In one embodiment, the S52, based on the joint state tracking library and the auxiliary planning knowledge base of each temperature control anomaly of each production node, updates the joint emergency processing auxiliary library of each administrator in real time, including:

[0111] S521, whenever the first incremental state set in the joint state tracking library within the most recent preset time matches the second incremental state set in the incremental state set triggering library, obtaining the auxiliary planning basis extraction template and the auxiliary planning target of the matching second incremental state set;

[0112] In S521, the most recent preset time may be within the last 100 seconds; the first incremental state set includes the work status of each administrator newly entered into the joint state tracking library within the most recent preset time; each work status in the second incremental state set jointly represents the need to re-assist the administrators, for example: each work status in the second incremental state set is that the amount of tasks handled by a certain administrator exceeds the predetermined range, resulting in delays or reduced efficiency, and a task that another administrator is responsible for is not completed on time, requiring reallocation of resources or assistance, etc.; when the first incremental state set matches the second incremental state set, it indicates that re-assistance planning is currently required for each administrator; the second incremental state set The auxiliary planning basis extraction template of the state set indicates how to extract the template of the auxiliary planning basis for re-assisting each administrator from the joint state tracking library. For example, if the working state in the second incremental state set is that the amount of tasks handled by a certain administrator exceeds the predetermined range, then the workload and progress of the current task handled by the administrator, the workload and progress of the tasks handled by other administrators around him, etc. are extracted; the auxiliary planning target of the second incremental state set indicates the target of auxiliary planning for each administrator. For example, if the working state in the second incremental state set is that the amount of tasks handled by a certain administrator exceeds the predetermined range, then reducing the amount of tasks handled by the administrator to not exceed the predetermined range is used as the auxiliary planning target;

[0113] S522, extracting auxiliary planning basis from the joint state tracking library based on the auxiliary planning basis extraction template;

[0114] S523, determining a plurality of auxiliary planning knowledge corresponding to the auxiliary planning target from the auxiliary planning knowledge base of each temperature control anomaly of each production node;

[0115] In S523, the auxiliary planning knowledge base for temperature control anomalies contains a plurality of auxiliary planning knowledge indicating how to plan for assisting the administrator to handle temperature control anomalies. The auxiliary planning knowledge may be expert experience for planning for assisting the administrator to handle temperature control anomalies.

[0116] S524, planning a plurality of auxiliary rules based on the auxiliary planning knowledge and the auxiliary planning basis;

[0117] In S524, based on the instructions of each auxiliary planning knowledge, auxiliary planning is performed according to the auxiliary planning basis, and multiple auxiliary rules are planned; specifically, for example, the auxiliary planning basis is the workload and progress of the current task handled by a certain administrator, the workload and progress of the tasks handled by other administrators around him, etc. The auxiliary planning knowledge indicates that the workload of each administrator is adjusted so that the workload does not exceed the respective predetermined ranges. Secondly, when adjusting, the tasks with lower execution progress at the administrator's hand are transferred to other administrators as much as possible. The generated auxiliary rules are specific rules for adjusting the workload of each administrator;

[0118] S525, based on the current contents of the emergency handling auxiliary library, jointly execute and arrange the auxiliary rules to obtain updated contents of the library;

[0119] In S525, the current library content refers to the content contained in the library before the emergency handling auxiliary library is updated. In order to make each auxiliary rule consistent with the auxiliary rules previously stored in the library during implementation and to achieve the most appropriate collaborative assistance for each administrator, based on the current library content, each auxiliary rule is adaptively and jointly executed and laid out, and then updated as the library update content.

[0120] S526. Update the joint emergency processing auxiliary library based on the library update content.

[0121] In the embodiment of the present invention, whenever the first incremental state set matches the second incremental state set, auxiliary planning is triggered, thereby improving the accuracy of determining the timing of auxiliary planning, reducing the system's resources for auxiliary planning, and improving the efficiency of auxiliary planning. Next, the auxiliary planning basis extraction template and auxiliary planning target of the matching second incremental state set are obtained, and the auxiliary planning basis is quickly extracted and the auxiliary planning knowledge is determined based on the two. There is no need to analyze all the contents in the joint state tracking library, which further reduces the system's resources for auxiliary planning, further improves the efficiency of auxiliary planning, and improves the utilization of the auxiliary planning knowledge base. Secondly, after multiple auxiliary rules are assisted in planning, each auxiliary rule is jointly executed and laid out based on the current contents of the emergency handling auxiliary library, thereby improving the accuracy and rationality of determining the library update content, and achieving the most accurate and appropriate update of the joint emergency handling auxiliary library.

[0122] In one embodiment, the step S525, based on the current contents of the emergency handling auxiliary library, jointly executing and arranging the auxiliary rules to obtain updated contents of the library, includes:

[0123] S5251. When each auxiliary rule only meets constraint 1, assign each auxiliary rule a first joint execution rule to obtain library update content;

[0124] S5252: When each auxiliary rule only meets constraint 1 and constraint 2 at the same time, assign a second joint execution rule to each auxiliary rule to obtain library update content;

[0125] S5253. When each auxiliary rule satisfies constraint 1, constraint 2, and constraint 3 at the same time, a third joint execution rule is assigned to each auxiliary rule to obtain library update content;

[0126] Among them, constraint one includes: the auxiliary planning knowledge based on which the auxiliary rules are planned is the same;

[0127] Constraint 2 includes: the auxiliary object of each auxiliary rule has a first target content corresponding to the content in the current library; the first target content is a historical auxiliary rule that is passively unexecuted;

[0128] Constraint three includes: the auxiliary object of each auxiliary rule has a corresponding second target content in the current library; the first target content is the historical auxiliary rule that has not been actively executed;

[0129] Among them, the first joint rule includes: immediately and simultaneously executing all auxiliary rules;

[0130] The second joint rule includes: executing the auxiliary rules in order from small to large according to the relevance between each auxiliary rule and the first target content;

[0131] The third joint rule includes: when the timing metric corresponding to the feature description vector in the timing metric library exceeds the threshold of the timing metric, the first joint rule is executed; otherwise, the second joint rule is executed; the feature description vector is obtained by feature describing the relative relationship between the first target content and the second target content in the current library.

[0132] In constraint one, an auxiliary planning knowledge fully instructs how to plan to assist the administrator in handling temperature control anomalies. Therefore, when each auxiliary rule only meets constraint one, each auxiliary rule needs to be executed simultaneously to conform to the instructions of the same auxiliary planning knowledge on which the planning is based, that is, to give each auxiliary rule the first joint execution rule.

[0133] In constraint two, historical auxiliary rules refer to the auxiliary rules previously stored in the database for assisting each administrator. Passive unexecuted completion refers to the situation where the administrator subjectively refuses to assist when the historical auxiliary rules are executed to assist each administrator. The greater the correlation between the auxiliary rules and the first target content, the later the execution is required. That is, when each auxiliary rule only meets constraints one and two at the same time, each auxiliary rule is assigned the second joint execution rule. The correlation between the auxiliary rules and the first target content refers to the correlation between the two rules, which represents the value of the degree of correlation between the two rules. For example, if the two rules are of the same type, the correlation is higher, which is 10. Specifically, the correlation between the auxiliary rules and the first target content can be set in advance by the technical staff. Sequential execution refers to the execution of the next auxiliary rule after a preset time interval after the execution of one auxiliary rule.

[0134] In constraint three, active non-execution means that the historical auxiliary rule is in the middle of execution, and the administrator has completed the work tasks that should be completed after the historical auxiliary rule is completed. This fully shows that the planning of the historical auxiliary rule meets the administrator's needs; the relative relationship between the first target content and the second target content in the current library refers to the difference between the sum of the historical execution orders of all the first target content and the sum of the historical execution orders of all the second target content, the average correlation between the first target content and the second target content, etc. The relative relationship is characterized to obtain a feature description vector. There are timing degrees corresponding to different feature description vectors in the timing degree library. The timing degree refers to the timing degree of the execution of the first joint rule. For example: the feature description is the relative relationship of the feature description vector, which includes the sum of the historical execution orders of all the first target content minus the historical execution orders of all the second target content. The difference of the sum is -20, and the average correlation between the first target content and the second target content is 0, which means that the first target content is generally generated before the execution of the second target content. In the later period, it often happens that the administrator has completed the work tasks that should be completed after the execution of the historical auxiliary rules in the middle of the execution. And the correlation degree between the first target content and the second target content is 0, which means that although the first target content was generated in the history, it has no effect on the simultaneous execution of all the current auxiliary rules. The timing degree is 80; the threshold of the timing degree can be 40; therefore, when the timing degree corresponding to the feature description vector in the timing degree library exceeds the threshold of the timing degree, the first joint rule is executed; otherwise, the second joint rule is executed, that is, when each auxiliary rule meets constraints one, two and three at the same time, each auxiliary rule is assigned the third joint execution rule to obtain the library update content.

[0135] The embodiment of the present invention introduces constraint one, constraint two and constraint three, and accurately determines the situation where joint execution layout is required according to the three situations that each auxiliary rule only meets constraint one, only meets constraint one and constraint two at the same time, and meets constraint one, constraint two and constraint three at the same time, which greatly improves the efficiency of joint execution layout of each auxiliary rule. Then, for different situations, the first joint rule, the second joint rule and the third joint rule are introduced respectively, and the rules are assigned, so that each auxiliary rule is consistent with the auxiliary rules that have been stored in the library before when implemented according to different joint rules, and can achieve the most appropriate collaborative assistance for each administrator, which greatly improves the applicability of the system. Secondly, for the most complex situation that meets constraint one, constraint two and constraint three at the same time, relative relationships, feature description vectors and timing degrees are introduced in the corresponding third joint rule to quickly determine whether to execute the first joint rule or the second joint rule, further improving the efficiency of joint execution layout of each auxiliary rule, and further improving the accuracy of joint execution layout.
