Description

Technical Field

[0001] The present invention relates to the technical field of feed fermentation, and in particular to an environment control method and system for mixed fermentation of animal and plant proteins. Background Art

[0002] Feed fermentation is a process that converts feed raw materials into biological feed with specific functions through the action of microorganisms. The purpose of feed fermentation is to make up for the amino acids that may be lacking in conventional feed, and at the same time, to quickly convert the nutrients of other roughage raw materials and enhance the digestion, absorption and utilization effect. Through the action of microorganisms, compound enzymes and other biological fermentation agents, feed raw materials are converted into microbial bacterial proteins, bioactive small peptide amino acids, microbial active probiotics, compound enzyme preparations, etc., to form a biological fermented feed. This feed is not only nutritious, but also can prevent microbial infection, improve feed digestibility, improve feed palatability, and promote mucosal immune response, which indirectly promotes the reduction of breeding costs. Through long-term feeding, fermented feed can help regulate intestinal microecology, promote feed digestion, improve feed palatability, and promote intestinal mucosal immunity. The active probiotics in the fermented feed play a role in balancing the intestinal microecological flora in the digestive tract, making the beneficial flora in a dominant position for a long time, inhibiting the reproduction of harmful bacteria by competing for space, nutrition and consuming oxygen, so that pathogens entering through the mouth are suppressed and killed, thereby reducing the incidence of intestinal diseases and improving breeding benefits.

[0003] Mixed fermentation of plant and animal proteins is an important step in producing high-quality feed or food. Through the fermentation process, the digestibility and nutritional value of protein can be improved, and the content of anti-nutritional factors can be reduced. However, the control of environmental parameters during the fermentation process is very critical, which directly affects the quality and efficiency of fermentation. In the prior art, human experience is usually relied on to judge and regulate the environmental parameters of feed fermentation, resulting in the inability to accurately control the fermentation environment, insufficient protein degradation, reduced activity of fermentation strains, or loss of nutrients.

[0004] Therefore, it is necessary to provide an environmental control method and system for mixed fermentation of animal and plant proteins to solve the problem that the fermentation environment cannot be accurately controlled in the prior art. Summary of the invention

[0005] In view of this, the present invention proposes an environmental control method and system for mixed fermentation of animal and plant proteins, aiming to solve the problem that the fermentation environment cannot be accurately controlled.

[0006] In one aspect, the present invention provides an environmental control method for mixed fermentation of animal and plant proteins, comprising:

[0007] The feed in the feed fermentation container is divided into an upper zone, a middle zone and a lower zone, and the feed temperature of different zones during the fermentation of the mixed fermented feed is collected in real time, and whether the fermented feed needs to be stirred is determined according to the feed temperature; when it is determined that stirring is required, the stirring time of the feed is determined according to the difference in the feed temperature between the zones;

[0008] After the stirring is completed, the feed temperature and the fermentation environment temperature are collected to determine whether the fermentation environment temperature should be adjusted. If it is determined to be adjusted, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time;

[0009] After the first adjustment is completed, the carbon dioxide concentration during the feed fermentation is collected to determine whether the fermentation environment temperature needs to be adjusted for a second time. If it is determined that a second adjustment is needed, the fermentation environment temperature is adjusted for a second time according to the carbon dioxide concentration and the remaining fermentation time;

[0010] After the secondary adjustment is completed, the feed humidity value is collected to determine whether the fermentation environment humidity needs to be adjusted. If it is determined to be adjusted, the current fermentation environment humidity is adjusted according to the ratio between the feed humidity value and the fermentation environment humidity.

[0011] Furthermore, the feed in the feed fermentation container is divided into an upper zone, a middle zone and a lower zone, and the feed temperature of different zones during the fermentation of the mixed fermented feed is collected in real time, and whether the fermented feed needs to be stirred is determined according to the feed temperature, including:

[0012] The feed portion in the fermentation container is evenly divided into an upper zone, a middle zone and a lower zone from top to bottom, and the feed temperature in the upper zone, the middle zone and the lower zone is collected in real time;

[0013] Generate the feed temperature change curve of the upper zone, the feed temperature change curve of the middle zone and the feed temperature change curve of the lower zone in real time respectively, and calculate the feed temperature difference between the upper zone and the middle zone and the feed temperature difference between the middle zone and the lower zone in real time at the same time;

[0014] The maximum value of the temperature difference between adjacent zones is preset. When the temperature difference between the upper zone and the middle zone and the temperature difference between the middle zone and the lower zone are both smaller than the maximum temperature values ​​of the adjacent zones, it is determined that the fermented feed does not need to be stirred.

[0015] When the feed temperature difference between the upper zone and the middle zone or the feed temperature difference between the middle zone and the lower zone is not lower than the maximum temperature of the adjacent zones, it is determined that the fermented feed needs to be stirred.

[0016] Furthermore, when it is determined that stirring is required, determining the stirring time of the feed according to the difference in feed temperature between the zones includes:

[0017] The larger value of the feed temperature difference between the upper zone and the middle zone and the feed temperature difference between the middle zone and the lower zone is selected to determine the feed stirring time, and the larger value is recorded as ΔT;

[0018] The basic stirring time when the feed temperature difference is equal to the maximum temperature of the adjacent area is preset, and the stirring time of the feed is calculated according to the following formula:

[0019] T1 = T × (ΔT / ΔTmax);

[0020] In the above formula, T1 represents the mixing time of feed, T represents the basic mixing time, and ΔTmax represents the maximum temperature difference between adjacent areas.

[0021] Furthermore, after the stirring is completed, the feed temperature and the fermentation environment temperature are collected, and it is determined whether to adjust the fermentation environment temperature, including:

[0022] If the feed temperature is equal to the fermentation environment temperature after the stirring is completed, it is determined that there is no need to adjust the fermentation environment temperature;

[0023] If the feed temperature is not equal to the fermentation environment temperature after the stirring is completed, it is determined that the fermentation environment temperature needs to be adjusted.

[0024] Furthermore, when it is determined to be an adjustment, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time, including:

[0025] Calculate the difference between the current feed temperature and the fermentation environment temperature according to the following formula, and determine whether adjustment is needed based on the size of the difference:

[0026] ΔW=W-Wh;

[0027] In the above formula, ΔW represents the difference between the current feed temperature and the fermentation environment temperature, W represents the current feed temperature, and Wh represents the fermentation environment temperature;

[0028] The standard fermentation environment temperature is preset, and the temperature adjustment coefficient is calculated according to the following formula. Whether to adjust the feed fermentation environment is determined according to the size of the temperature adjustment coefficient:

[0029] Kw=(ΔW / Wb)×(ts / tz);

[0030] In the above formula, Kw represents the temperature adjustment coefficient, ΔW represents the difference between the current feed temperature and the fermentation environment temperature, Wb represents the standard fermentation environment temperature, ts represents the remaining fermentation time, and tz represents the total fermentation time;

[0031] When Kw>1, the fermentation environment temperature is lowered until the feed temperature is equal to the fermentation environment temperature;

[0032] When Kw < 1, the fermentation environment temperature is increased until the feed temperature is equal to the fermentation environment temperature;

[0033] When Kw=1, there is no need to adjust the fermentation environment temperature.

[0034] Furthermore, after the primary adjustment is completed, the carbon dioxide concentration during feed fermentation is collected to determine whether to perform a secondary adjustment on the fermentation environment temperature, including:

[0035] Presetting a maximum carbon dioxide concentration, and when the carbon dioxide concentration is greater than the maximum carbon dioxide concentration, determining that a secondary adjustment of the fermentation environment temperature is required;

[0036] When the carbon dioxide concentration is less than or equal to the maximum carbon dioxide concentration, it is determined that there is no need to perform a secondary adjustment on the fermentation environment temperature.

[0037] Further, when it is determined that a secondary adjustment is required, the fermentation environment temperature is secondary adjusted according to the carbon dioxide concentration and the remaining fermentation time, including:

[0038] Calculate CO according to the following formula 2 Adjustment factor, according to CO 2 The adjustment coefficient adjusts the fermentation environment temperature to obtain the fermentation environment temperature after secondary adjustment:

[0039] Kco 2 =(CO 2 -CO 2 max) / CO 2 max×(ts / tz);

[0040] W1=Kco 2 ×W;

[0041] In the above formula, Kco 2 Indicates CO 2 Adjustment factor, CO 2 Indicates the current carbon dioxide concentration, CO 2 max represents the maximum carbon dioxide concentration, ts represents the remaining fermentation time, tz represents the total fermentation time, W1 represents the fermentation environment temperature after secondary adjustment, and W represents the current fermentation environment temperature.

[0042] Further, after the secondary adjustment is completed, the feed humidity value is collected to determine whether the fermentation environment humidity needs to be adjusted, including:

[0043] A standard ratio between the humidity value of the feed and the humidity of the fermentation environment is preset. If the ratio between the humidity value of the feed and the humidity of the fermentation environment after stirring is equal to the standard ratio, it is determined that the humidity of the fermentation environment does not need to be adjusted;

[0044] If the ratio of the humidity value of the feed after stirring to the humidity of the fermentation environment is not equal to the standard ratio, it is determined that the humidity of the fermentation environment needs to be adjusted.

[0045] Furthermore, the step of adjusting the current fermentation environment humidity according to the ratio between the feed humidity value and the fermentation environment humidity includes:

[0046] If the ratio of the humidity value of the feed to the humidity of the fermentation environment after stirring is greater than the standard ratio, increasing the humidity of the fermentation environment until the ratio of the humidity value of the feed to the humidity of the fermentation environment is equal to the standard ratio;

[0047] If the ratio of the humidity value of the feed after stirring to the humidity of the fermentation environment is less than the standard ratio, the humidity of the fermentation environment is reduced until the ratio of the humidity value of the feed to the humidity of the fermentation environment is equal to the standard ratio.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] The present invention divides the feed fermentation container into an upper zone, a middle zone and a lower zone, and collects temperature data of each zone in real time, so that the temperature monitoring of the fermentation process is more accurate and dynamic, and it can timely judge whether a stirring operation is needed, thereby effectively improving the uniformity and efficiency of the fermentation process; the stirring time is automatically calculated according to the difference in feed temperature between the zones, so that unnecessary excessive stirring can be avoided, energy consumption can be saved and the impact on the fermentation quality can be reduced; in addition, by collecting the feed temperature after stirring and the fermentation environment temperature, the fermentation environment temperature can be flexibly adjusted to ensure that the fermentation process is always in the optimal temperature range; the monitoring of carbon dioxide concentration and the secondary adjustment of the fermentation environment temperature can help avoid the adverse effects of excessive carbon dioxide concentration on the fermentation process and ensure the stability of the fermentation environment; the dynamic adjustment of the fermentation environment humidity helps to maintain a suitable humidity level during the fermentation process by monitoring the ratio of feed to environment humidity, prevent over-wetting or over-drying, and further optimize the fermentation effect.

[0050] On the other hand, the present application also provides an environmental control system for mixed fermentation of animal and plant proteins, comprising:

[0051] The stirring control module is configured to divide the feed in the feed fermentation container into an upper zone, a middle zone and a lower zone, collect the feed temperature of different zones during the fermentation of the mixed fermented feed in real time, and judge whether the fermented feed needs to be stirred according to the feed temperature; when it is judged that stirring is needed, determine the stirring time of the feed according to the difference of the feed temperature between the zones;

[0052] The temperature control module is configured to collect the feed temperature and the fermentation environment temperature after the stirring is completed, and determine whether to adjust the fermentation environment temperature. If it is determined to be adjusted, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time;

[0053] The temperature control module is also configured to collect the carbon dioxide concentration during the fermentation of the feed after the primary adjustment is completed, and determine whether to make a secondary adjustment to the fermentation environment temperature. When it is determined that a secondary adjustment is required, the fermentation environment temperature is adjusted secondary according to the carbon dioxide concentration and the remaining fermentation time;

[0054] The humidity control module is configured to collect the feed humidity value after the secondary adjustment is completed, and determine whether the fermentation environment humidity needs to be adjusted. When it is determined to be adjusted, the current fermentation environment humidity is adjusted according to the ratio between the feed humidity value and the fermentation environment humidity.

[0055] It is understandable that the environmental control method and system for mixed fermentation of animal and plant proteins provided in the present application have the same beneficial effects and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0060] In some embodiments of the present application, see Figure 1As shown, this embodiment provides an environmental control method for mixed fermentation of animal and plant proteins, comprising the following steps:

[0061] S100, dividing the feed in the feed fermentation container into an upper zone, a middle zone and a lower zone, collecting the feed temperature of different zones during the fermentation of the mixed fermented feed in real time, and judging whether the fermented feed needs to be stirred according to the feed temperature; when it is judged that stirring is needed, determining the stirring time of the feed according to the difference in feed temperature between the zones;

[0062] S200, after the stirring is completed, the feed temperature and the fermentation environment temperature are collected to determine whether the fermentation environment temperature is to be adjusted. If it is determined to be adjusted, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time;

[0063] S300, after the primary adjustment is completed, the carbon dioxide concentration during the feed fermentation is collected to determine whether a secondary adjustment is required for the fermentation environment temperature. When it is determined that a secondary adjustment is required, the fermentation environment temperature is secondary adjusted according to the carbon dioxide concentration and the remaining fermentation time;

[0064] S400, after the secondary adjustment is completed, the feed humidity value is collected to determine whether the fermentation environment humidity needs to be adjusted. If it is determined to be adjusted, the current fermentation environment humidity is adjusted according to the ratio between the feed humidity value and the fermentation environment humidity.

[0065] It can be understood that the present invention divides the feed fermentation container into an upper zone, a middle zone and a lower zone, and collects temperature data of each zone in real time, so that the temperature monitoring of the fermentation process is more accurate and dynamic, and it can timely determine whether stirring operation is needed, effectively improving the uniformity and efficiency of the fermentation process; the stirring time is automatically calculated according to the difference in feed temperature between the zones, which can avoid unnecessary excessive stirring, save energy consumption and reduce the impact on fermentation quality; in addition, by collecting the feed temperature after stirring and the fermentation environment temperature, the fermentation environment temperature can be flexibly adjusted to ensure that the fermentation process is always in the optimal temperature range; the monitoring of carbon dioxide concentration and the secondary adjustment of the fermentation environment temperature can help avoid the adverse effects of excessive carbon dioxide concentration on the fermentation process and ensure the stability of the fermentation environment; the dynamic adjustment of the fermentation environment humidity helps to maintain a suitable humidity level during the fermentation process by monitoring the ratio of feed to environmental humidity, prevent over-wetting or over-drying, and further optimize the fermentation effect.

[0066] In some embodiments of the present application, the feed in the feed fermentation container is divided into an upper zone, a middle zone and a lower zone, and the feed temperature of different zones during the fermentation of the mixed fermented feed is collected in real time. When judging whether the fermented feed needs to be stirred according to the feed temperature, the method includes:

[0067] The feed portion in the fermentation container is evenly divided into an upper zone, a middle zone and a lower zone from top to bottom, and the feed temperature in the upper zone, the middle zone and the lower zone is collected in real time;

[0068] Generate the feed temperature change curve of the upper zone, the feed temperature change curve of the middle zone and the feed temperature change curve of the lower zone in real time respectively, and calculate the feed temperature difference between the upper zone and the middle zone and the feed temperature difference between the middle zone and the lower zone in real time at the same time;

[0069] The maximum value of the temperature difference between adjacent zones is preset. When the temperature difference between the upper zone and the middle zone and the temperature difference between the middle zone and the lower zone are both less than the maximum temperature of the adjacent zones, it is determined that the fermented feed does not need to be stirred.

[0070] When the feed temperature difference between the upper zone and the middle zone or the feed temperature difference between the middle zone and the lower zone is not lower than the maximum temperature of the adjacent zones, it is determined that the fermented feed needs to be stirred.

[0071] It is understandable that the present invention can more accurately monitor the temperature changes of each area during the fermentation process by dividing the fermentation container into an upper area, a middle area and a lower area, and collecting the feed temperature of different areas in real time. By generating the temperature change curve of each area and calculating the temperature difference, it can automatically determine whether stirring is required based on the preset maximum value of the temperature difference between adjacent areas, avoiding the uncertainty caused by reliance on human experience, ensuring the uniformity of feed fermentation, reducing the risk of insufficient or excessive fermentation, thereby improving the quality and consistency of the fermented product, while optimizing the fermentation efficiency and reducing energy consumption and operating costs.

[0072] In some embodiments of the present application, when it is determined that stirring is required, determining the stirring time of the feed according to the difference in feed temperature between the zones includes:

[0073] The larger value of the feed temperature difference between the upper zone and the middle zone and the feed temperature difference between the middle zone and the lower zone is selected to determine the feed mixing time, and the larger value is recorded as ΔT;

[0074] The basic mixing time is preset when the feed temperature difference is equal to the maximum temperature of the adjacent area, and the mixing time of the feed is calculated according to the following formula:

[0075] T1 = T × (ΔT / ΔTmax);

[0076] In the above formula, T1 represents the mixing time of feed, T represents the basic mixing time, and ΔTmax represents the maximum temperature difference between adjacent areas.

[0077] It is understandable that by introducing the temperature difference between adjacent zones to determine the feed mixing time, the accuracy of the mixing process is improved. By selecting the larger temperature difference between the upper zone and the middle zone, and between the middle zone and the lower zone as a reference, the degree of temperature unevenness in each zone can be more effectively reflected, ensuring that the mixing intensity matches the actual needs. The mixing time calculation ensures that when the temperature difference is greater, the mixing time is longer, thereby better improving the fermentation uniformity, optimizing the mixing process according to different fermentation conditions, improving fermentation efficiency and product quality, and reducing unnecessary energy consumption and resource waste during the fermentation process.

[0078] In some embodiments of the present application, after the stirring is completed, the feed temperature and the fermentation environment temperature are collected, and it is determined whether to adjust the fermentation environment temperature, including:

[0079] If the feed temperature is equal to the fermentation environment temperature after stirring, it is determined that there is no need to adjust the fermentation environment temperature;

[0080] If the feed temperature is not equal to the fermentation environment temperature after stirring, it is determined that the fermentation environment temperature needs to be adjusted.

[0081] In some embodiments of the present application, when it is determined to be an adjustment, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time, including:

[0082] Calculate the difference between the current feed temperature and the fermentation environment temperature according to the following formula, and determine whether adjustment is needed based on the size of the difference:

[0083] ΔW=W-Wh;

[0084] In the above formula, ΔW represents the difference between the current feed temperature and the fermentation environment temperature, W represents the current feed temperature, and Wh represents the fermentation environment temperature;

[0085] The standard fermentation environment temperature is preset, and the temperature adjustment coefficient is calculated according to the following formula. Whether to adjust the feed fermentation environment is determined according to the size of the temperature adjustment coefficient:

[0086] Kw=(ΔW / Wb)×(ts / tz);

[0087] In the above formula, Kw represents the temperature adjustment coefficient, ΔW represents the difference between the current feed temperature and the fermentation environment temperature, Wb represents the standard fermentation environment temperature, ts represents the remaining fermentation time, and tz represents the total fermentation time;

[0088] When Kw>1, the fermentation environment temperature is lowered until the feed temperature is equal to the fermentation environment temperature;

[0089] When Kw < 1, the fermentation environment temperature is increased until the feed temperature is equal to the fermentation environment temperature;

[0090] When Kw=1, there is no need to adjust the fermentation environment temperature.

[0091] It is understandable that the automatic adjustment of the feed fermentation environment temperature avoids the errors that may be caused by traditional manual judgment. By collecting the difference between the feed temperature and the fermentation environment temperature after the mixing is completed, and calculating the temperature adjustment coefficient in combination with the remaining fermentation time, it is possible to dynamically determine whether heating or cooling operations are required. The temperature adjustment coefficient Kw is based on the actual temperature difference and the fermentation process, ensuring that necessary temperature adjustments are made when the temperature difference is large, and avoiding excessive adjustments when the fermentation is nearing the end, thereby realizing intelligent and precise temperature control, improving the stability and uniformity of the fermentation process, and helping to improve the quality of fermented products while reducing energy waste and operational complexity.

[0092] In some embodiments of the present application, after the primary adjustment is completed, the carbon dioxide concentration during feed fermentation is collected, and it is determined whether to perform a secondary adjustment on the fermentation environment temperature, including:

[0093] The maximum carbon dioxide concentration is preset. When the carbon dioxide concentration is greater than the maximum carbon dioxide concentration, it is determined that the fermentation environment temperature needs to be adjusted for a second time.

[0094] When the carbon dioxide concentration is less than or equal to the maximum carbon dioxide concentration, it is determined that there is no need to make a secondary adjustment to the fermentation environment temperature.

[0095] In some embodiments of the present application, when it is determined that secondary adjustment is required, the fermentation environment temperature is secondary adjusted according to the carbon dioxide concentration and the remaining fermentation time, including:

[0096] Calculate CO according to the following formula 2 Adjustment factor, according to CO 2 The adjustment coefficient adjusts the fermentation environment temperature to obtain the fermentation environment temperature after secondary adjustment:

[0097] Kco 2 =(CO 2 -CO 2 max) / CO 2 max×(ts / tz);

[0098] W1=Kco 2 ×W;

[0099] In the above formula, Kco 2 Indicates CO 2 Adjustment factor, CO 2 Indicates the current carbon dioxide concentration, CO 2max represents the maximum carbon dioxide concentration, ts represents the remaining fermentation time, tz represents the total fermentation time, W1 represents the fermentation environment temperature after secondary adjustment, and W represents the current fermentation environment temperature.

[0100] It is understood that by real-time monitoring of the concentration of carbon dioxide during the fermentation process and automatically adjusting the fermentation environment temperature in combination with the remaining fermentation time, the stability of the fermentation process is ensured. By setting the maximum carbon dioxide concentration, when the actual concentration exceeds this value, the CO 2 The adjustment coefficient and the ambient temperature are adjusted accordingly to prevent the negative impact of excessive carbon dioxide concentration on fermentation. It can not only accurately respond to environmental changes caused by metabolic changes during the fermentation process, but also dynamically optimize temperature control through the remaining fermentation time, avoid excessive or insufficient adjustment operations, and improve fermentation efficiency.

[0101] In some embodiments of the present application, after the secondary adjustment is completed, the feed humidity value is collected to determine whether the fermentation environment humidity needs to be adjusted, including:

[0102] A standard ratio between the humidity value of the feed and the humidity of the fermentation environment is preset. If the ratio between the humidity value of the feed and the humidity of the fermentation environment after stirring is equal to the standard ratio, it is determined that the humidity of the fermentation environment does not need to be adjusted;

[0103] If the ratio of the humidity value of the feed after stirring to the humidity of the fermentation environment is not equal to the standard ratio, it is judged that the humidity of the fermentation environment needs to be adjusted.

[0104] In some embodiments of the present application, when adjusting the current fermentation environment humidity according to the ratio between the feed humidity value and the fermentation environment humidity, it includes:

[0105] If the ratio of the humidity value of the feed to the humidity of the fermentation environment after stirring is greater than the standard ratio, the humidity of the fermentation environment is increased until the ratio of the humidity value of the feed to the humidity of the fermentation environment is equal to the standard ratio;

[0106] If the ratio of the humidity value of the feed to the humidity of the fermentation environment after stirring is less than the standard ratio, the humidity of the fermentation environment should be reduced until the ratio of the humidity value of the feed to the humidity of the fermentation environment is equal to the standard ratio.

[0107] It is understandable that by collecting the feed humidity value after the secondary adjustment in real time and comparing it with the fermentation environment humidity, the humidity of the fermentation environment is dynamically adjusted to ensure the optimal humidity conditions of the fermentation process. By setting a standard humidity ratio, when the ratio of feed humidity to fermentation environment humidity deviates from the standard, the ambient humidity is automatically increased or decreased to return the humidity ratio to the standard range. The negative impact of excessively high or low humidity on fermentation is avoided, especially preventing poor fermentation caused by excessive dryness or over-humidity, thereby improving the fermentation efficiency and the quality of the final product.

[0108] On the other hand, see Figure 2 As shown, the present application also provides an environmental control system for mixed fermentation of animal and plant proteins, which is used to apply the above-mentioned environmental control method for mixed fermentation of animal and plant proteins, including:

[0109] The stirring control module is configured to divide the feed in the feed fermentation container into an upper zone, a middle zone and a lower zone, collect the feed temperature of different zones during the fermentation of the mixed fermented feed in real time, and determine whether the fermented feed needs to be stirred according to the feed temperature; when it is determined that stirring is required, the stirring time of the feed is determined according to the difference in feed temperature between the zones;

[0110] The temperature control module is configured to collect the feed temperature and the fermentation environment temperature after the stirring is completed, and determine whether to adjust the fermentation environment temperature. If it is determined to be adjusted, the fermentation environment temperature is adjusted once according to the feed temperature and the remaining fermentation time;

[0111] The temperature control module is also configured to collect the carbon dioxide concentration during the fermentation of the feed after the primary adjustment is completed, and determine whether to make a secondary adjustment to the fermentation environment temperature. If it is determined that a secondary adjustment is required, the fermentation environment temperature is adjusted secondary according to the carbon dioxide concentration and the remaining fermentation time;

[0112] The humidity control module is configured to collect the feed humidity value after the secondary adjustment is completed, and determine whether the fermentation environment humidity needs to be adjusted. When it is determined to be adjusted, the current fermentation environment humidity is adjusted according to the ratio between the feed humidity value and the fermentation environment humidity.

[0113] It is understandable that the present invention realizes all-round intelligent control of the mixed fermentation process of animal and plant proteins. The stirring control module ensures real-time monitoring of the temperature of each fermentation area, and accurately determines whether stirring is needed according to the temperature difference, automatically adjusts the stirring time according to the temperature difference, ensures uniform temperature after stirring, and adjusts the ambient temperature in time; the temperature control module ensures accurate adjustment of the ambient temperature during the fermentation process by monitoring the carbon dioxide concentration; the humidity control module ensures that the fermentation environment is in the optimal state by dynamically adjusting the fermentation humidity. The present invention improves the fermentation efficiency and quality as a whole, reduces human intervention, optimizes the temperature and humidity control during the fermentation process, and makes the final product more stable and efficient.
