Description

Technical Field

[0001] This invention relates to the field of baijiu brewing technology, specifically to a baijiu brewing temperature and humidity control system, method, storage medium, and equipment. Background Technology

[0002] In the traditional brewing process of baijiu, fermentation is the core link that determines the flavor, yield and quality of the liquor. During this process, the temperature and humidity environment of the brewing raw materials (such as mash) is crucial. Too high a temperature will inhibit the activity of microorganisms, resulting in insufficient fermentation or even spoilage; too low a temperature will slow down the fermentation and prolong the production cycle. Too high a humidity will easily cause the growth of miscellaneous bacteria, while too low a humidity will cause the raw materials to dry out and affect the fermentation efficiency. Currently, many breweries, especially small and medium-sized enterprises, still have a relatively crude control over the fermentation environment. The common approach is to rely on manual experience and make adjustments by simply opening doors and windows, or by using basic ventilation equipment. This approach has significant limitations: First, it cannot achieve independent and precise temperature and humidity monitoring and control for each fermentation unit (fermentation chamber), resulting in an uneven environment throughout the fermentation room and significant quality differences between fermentation chambers in different locations. Second, the control is lagging and inaccurate, heavily reliant on manual inspections, and cannot respond to environmental changes in real time. This can easily cause fermentation conditions to deviate from the optimal range, leading to problems such as high loss of brewing raw materials, unstable alcohol yield, and high energy consumption. Finally, the lack of an automated over-temperature and over-humidity protection mechanism poses a risk of batch quality accidents. Therefore, there is an urgent need in this field for a technical solution that can achieve independent, precise, and automated temperature and humidity control for each fermentation chamber, so as to fundamentally improve the stability, quality, and efficiency of baijiu production. Summary of the Invention

[0003] The purpose of this invention is to provide a temperature and humidity control system, method, storage medium, and equipment for brewing baijiu (Chinese liquor) to solve the problems mentioned in the background art, such as inaccurate control, reliance on manual experience leading to low production efficiency, high energy consumption, and lack of effective automated protection mechanisms.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a temperature and humidity control system for baijiu brewing, comprising: The main control unit is located inside the electrical control box; The fermentation environment unit includes a main fermentation room, the size of which can be adjusted according to the site; the main fermentation room contains at least one fermentation box. An environmental control module is installed in the main fermentation chamber and includes a blower, an exhaust fan, a blower damper motor, an exhaust damper motor, a heating device, and a humidification device. The number of blowers, exhaust fans, heating devices, and humidifying devices increases as the main fermentation chamber increases in size; The sensing module includes a main temperature sensor and a main humidity sensor installed in the main fermentation chamber, and multiple fermentation temperature sensors installed in each of the fermentation chambers. The main control unit is electrically connected to the environmental control module and the sensing module, and is configured to control the operation of the environmental control module according to the feedback signal of the sensing module, so as to maintain the temperature and humidity in the fermentation chamber within a set range.

[0005] Preferably, the main control unit is configured to execute a temperature control method, including: When the temperature collected by the sensing module is lower than the first temperature setting value, the heating device is activated; When the collected temperature reaches the second temperature set value, the heating device is stopped; When the collected temperature reaches a third temperature setting value that is higher than the second temperature setting value, the air supply damper and the air exhaust damper are opened, and after a delay, the air supply fan and the air exhaust fan are started to cool down. When the temperature drops to the second temperature setpoint or a stop temperature signal value, the blower and exhaust fan are stopped and the damper is closed.

[0006] Preferably, the third temperature setting value is 6 degrees Celsius higher than the second temperature setting value.

[0007] Preferably, the main control unit is configured to execute a humidity control method, including: When the humidity collected by the sensing module is lower than the first humidity setting value, the humidification device is activated; When the collected humidity reaches the second humidity setting value, the humidification device is stopped. When the collected humidity reaches a third humidity setting value that is higher than the second humidity setting value, the supply air damper and exhaust air damper are opened, and after a delay, the supply air fan and exhaust air fan are started to reduce humidity. When the humidity drops to the second humidity set value or a stop humidity signal value, the supply fan and exhaust fan are stopped and the damper is closed.

[0008] Preferably, the third humidity setting value is at least 10%RH higher than the second humidity setting value.

[0009] Preferably, the system further includes a display alarm unit; the display alarm unit is configured to: When the temperature detected by any of the fermentation temperature sensors is within the normal range, a green indicator light will be displayed; When the detected temperature exceeds an over-temperature alarm temperature, a red indicator light will be displayed and an audible alarm will be triggered.

[0010] A method for controlling temperature and humidity during the brewing of baijiu (Chinese liquor), the method being implemented by the system described above, including the temperature and humidity control method.

[0011] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the aforementioned method for controlling temperature and humidity in the brewing of baijiu (Chinese liquor).

[0012] A brewing apparatus, including the aforementioned temperature and humidity control system for baijiu brewing. Compared with the prior art, the beneficial effects of the present invention are: the temperature and humidity control system for liquor brewing: 1. It has a high degree of modularity and scalability. The size of the main fermentation chamber and the number of internal equipment such as blowers, exhaust fans, heating devices, and humidification devices can be configured according to actual production capacity requirements. By increasing the volume of the fermentation chamber and increasing the number of fermentation boxes, the fermentation batches can be easily rotated, achieving daily-level large-scale production capacity. While ensuring quality, it improves production efficiency and greatly increases production capacity. 2. By installing sensors in the main fermentation room and each fermentation chamber, and combining them with the intelligent judgment of the main control unit, precise closed-loop control of the temperature and humidity of the fermentation environment can be achieved. This ensures that the entire fermentation process is always within the optimal process range, greatly reducing quality variations caused by environmental fluctuations, making the flavor of the wine more stable and pure, and fundamentally improving the product quality standards. 3. The system operates fully automatically without the need for frequent manual intervention. It adopts a hierarchical control strategy: basic adjustment is first made through heating / humidification devices, and the fan is activated for strong intervention only when the temperature and humidity exceed a higher threshold. This mode of "small adjustments rely on equipment, and large interventions rely on ventilation" avoids ineffective energy waste. Compared with traditional continuous ventilation or extensive temperature control methods, it significantly reduces energy consumption and achieves energy conservation and emission reduction. 4. By setting up a dual temperature and humidity protection mechanism, when the basic temperature / humidity control device fails to maintain the parameters within the set range and touches a higher protection threshold, the system will automatically start the supply / exhaust fan for forced ventilation to cool / dehumidify. This mechanism effectively prevents serious accidents such as "box burning" or mold growth caused by system failure or sudden environmental changes, ensuring the reliability and safety of the production process. 5. The system integrates a display and alarm unit, which can intuitively display the working status of each fermentation chamber in real time through green lights, red lights and audible alarms. Once an abnormal overtemperature occurs in a fermentation chamber, the operator can find and locate the problem immediately, which greatly facilitates production monitoring and management and reduces quality risks.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-4 The present invention provides a technical solution: a temperature and humidity control system for baijiu brewing.

[0017] Example: Specific implementation of a temperature and humidity control system for Baijiu brewing 1. System Composition This system mainly includes the following parts: Main control unit 13: The core is a main control board set in the electrical control box 2, which can be a PLC (programmable logic controller) or an industrial-grade microcontroller, responsible for processing all sensor signals and issuing control commands.

[0018] Fermentation environment unit: includes a sealed main fermentation room 1, the size of which can be customized according to the actual site and production capacity requirements of the winery, and contains multiple fermentation boxes 9 for holding the mash.

[0019] Environmental control module: All are installed inside the main fermentation chamber 1, including: Ventilation equipment: supply fan 5 and exhaust fan 6 for cooling and dehumidification, and supply damper motor 3 and exhaust damper motor 4 for controlling the opening and closing of their ducts respectively.

[0020] Temperature and humidity control equipment: several sets of temperature heating devices 8 (such as graphene heating devices) and humidity humidification devices 11 (such as high-pressure micro-mist humidifiers).

[0021] Sensing module: Used for real-time monitoring of environmental parameters, including: A main temperature sensor 7 and a main humidity sensor 10 are installed in the main fermentation chamber 1 to monitor the overall environment.

[0022] Multiple fermentation temperature sensors 12, with at least one installed in each fermentation chamber 9, are used to monitor the temperature of the core area of ​​each fermentation chamber 9.

[0023] Display alarm unit: can be installed on the control box 2 panel, including green / red indicator lights and buzzers for displaying the status of each fermentation tank 9.

[0024] All of the above components are electrically connected to the main control unit 13, forming a complete closed-loop control system.

[0025] 2. Work Process Temperature control process: Basic heating control: After system initialization, the main control unit 13 continuously reads the data from the main temperature sensor 7 and each fermentation temperature sensor 12. After the user sets the optimal fermentation temperature range, when any representative sensor detects that the temperature is lower than the user-set optimal fermentation temperature range, the main control unit 13 starts the heating device 8 to heat.

[0026] Stop heating: When the temperature rises to the maximum value of the optimal fermentation temperature range set by the user, the main control unit 13 cuts off the power to the heating device 8 and stops heating.

[0027] Dual protection - forced cooling: To prevent temperature runaway due to sudden rise in ambient temperature or equipment failure, the system sets a third temperature setpoint. When the detected temperature reaches the third temperature setpoint, the main control unit 13 immediately executes the forced cooling program: First, it controls the air supply damper motor 3 and the exhaust damper motor 4 to open the dampers. After a 20-second delay to ensure the air duct is completely unobstructed, it starts the air supply fan 5 and the exhaust fan 6 to introduce cool outside air for powerful ventilation and cooling.

[0028] Stop cooling: When the temperature drops back to the optimal fermentation temperature range set by the user, the main control unit 13 issues a command to stop the blower 5 and the exhaust fan 6, and then closes their dampers to restore the closed fermentation state.

[0029] Humidity control process: Basic humidification control: After the user sets the optimal humidity range, when the main humidity sensor 10 detects that the humidity is lower than the user-set optimal humidity range, the main control unit 13 starts the humidification device 11 to humidify.

[0030] Humidification stops: When the humidity reaches the maximum value of the user-set optimal humidity range, the humidifier 11 stops working.

[0031] Dual protection - forced dehumidification: When the humidity exceeds the optimal humidity range set by the user, the main control unit 13 also starts the forced dehumidification program: the damper is opened, and after a delay of 20 seconds, the supply fan 5 and exhaust fan 6 are started to reduce the ambient humidity by strengthening air circulation.

[0032] Stop dehumidification: When the humidity drops to the maximum value of the user-set optimal humidity range, turn off the fan and damper.

[0033] 3. Display and Alarm On the corresponding display panel of each fermentation chamber 9, the green light indicates that the temperature of the chamber is normal. If a fermentation temperature sensor 12 detects that the temperature exceeds the safe range, the corresponding red light will light up and the buzzer will sound to remind the staff to intervene in time.

[0034] 4. Extended Applications For wineries that need to expand their production capacity, the size of the main fermentation room 1 can be increased proportionally, and the number of blowers 5, exhaust fans 6, heating devices 8 and humidification devices 11 can be increased accordingly to ensure the uniformity and effectiveness of temperature and humidity control in the large space. By arranging multiple fermentation boxes 9 to enter the room for fermentation at different times, assembly line operation can be achieved to achieve the goal of daily mass production.

[0035] This embodiment, through the above specific implementation, achieves precise and automated control of the liquor fermentation environment, especially of each independent fermentation tank 9. This not only significantly improves the stability and yield of liquor quality, but also greatly saves energy consumption and reduces raw material loss and production risks due to on-demand regulation and dual protection mechanisms.

[0036] Meanwhile, the technical solution of this application is not limited to the brewing of baijiu. After appropriate process parameter adaptation, it can also be applied to the temperature and humidity control of the fermentation process of other alcoholic beverages such as brandy and wine, providing a reliable environmental guarantee for the large-scale and standardized production of various alcoholic beverages.
