Description

Technical Field

[0002] The fruit wine fermentation tank is a key equipment in the fruit wine production process, which is used for the fermentation process of fruit wine. In the process of fruit wine fermentation, the control of temperature and pressure is the key factor to ensure the quality of fruit wine. Temperature directly affects the activity of yeast and the formation of metabolites, while pressure is related to the production and emission of carbon dioxide. In order to ensure the fermentation speed, flavor and quality of fruit wine, the temperature and pressure in the fermentation tank need to be controlled.

[0003] During the fermentation process, the temperature inside the fermentation tank is one of the key factors affecting the growth and metabolism of microorganisms. As the fermentation time changes, the metabolic activities of the microorganisms will generate heat, causing the temperature inside the tank to rise. If the temperature is not properly controlled, it may have a negative impact on the growth of microorganisms and even cause the fermentation process to fail.

[0004] During the fermentation process, in order to prevent the fermentation tank from being damaged or the wine from overflowing due to excessive pressure, a pressure sensor is usually used to monitor the pressure inside the tank. However, the pressure sensor is greatly affected by the ambient temperature. In practical applications, the internal resistance of the pressure sensor often changes due to changes in the temperature in the fermentation tank, resulting in unstable working voltage of the pressure sensor, and the inability to accurately discharge the carbon dioxide in the fermentation tank, thus affecting the quality of the wine.

In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment proposes a remote monitoring type intelligent fermentation controller, including a power supply, a pressure monitoring unit, a processor and a communication module;

[0040] The power supply is connected to a first end of the pressure monitoring unit, and a second end of the pressure monitoring unit is connected to the processor;

[0041] The pressure monitoring unit is used to monitor the pressure in the fermentation tank, and the pressure monitoring unit includes a voltage adjustment module and a pressure monitoring module;

[0042] The processor is connected to the terminal through the communication module;

[0043] A first end of the voltage adjustment module is connected to a power source, a second end of the voltage adjustment module is connected to a pressure monitoring module, and a second end of the pressure monitoring module is connected to a processor;

[0044] The voltage adjustment module is configured to control the working voltage of the pressure monitoring module according to the current flowing through the pressure monitoring module.

[0045] The fruit wine fermentation tank is a key equipment in the fruit wine production process, which is used for the fermentation process of fruit wine. Pressure monitoring of the fruit wine fermentation tank is an important link to ensure the quality and production safety of fruit wine. The pressure inside the fermentation tank will change due to factors such as carbon dioxide produced during the fermentation process and temperature changes. Too high or too low pressure may affect the fermentation process of fruit wine and its final quality. Therefore, real-time monitoring of the pressure inside the fermentation tank is crucial for the production of high-quality fruit wine.

[0046] The internal resistance of the pressure sensor is greatly affected by temperature. During the fermentation process of fruit wine, the temperature in the fermentation tank will change. When the temperature of the pressure monitoring environment changes, the internal resistance of the pressure sensor will change. Therefore, the current flowing through the pressure sensor will change, affecting the stability of the pressure sensor.

[0047] In this embodiment, the pressure monitoring unit monitors the pressure in the fermentation tank through a pressure sensor. The pressure monitoring unit is composed of a voltage adjustment module and a pressure monitoring module. The pressure monitoring module is used to monitor the pressure in the fermentation tank, and the power supply is used to provide a working voltage for the pressure monitoring module. The voltage adjustment module can adjust the working voltage of the pressure monitoring module according to the current flowing through the pressure monitoring module, thereby changing the working current of the pressure monitoring module, ensuring that the current flowing through the pressure monitoring module is stable and unchanged, and improving the stability of the power supply voltage of the pressure monitoring module. In this embodiment, a pressure sensor is used as the pressure monitoring module.

[0048] The pressure monitoring module is used to convert the pressure signal in the fermentation tank into an electrical signal and send it to the processor. When the pressure in the fermentation tank exceeds the set value, the processor can send the pressure in the fermentation tank to the terminal through the communication module. The pressure in the fermentation tank can be displayed on the terminal so that the staff can view it and take corresponding measures according to the pressure. The terminal in this embodiment can be a monitoring room or a mobile phone.

[0049] In this embodiment, the pressure monitoring module is used to monitor the pressure in the fermentation tank, and convert the monitored pressure signal into an electrical signal and send it to the processor. When the pressure in the fermentation tank exceeds the set value, the processor can send the pressure situation in the fermentation tank to the terminal through the communication module so that the staff can view it in real time. The staff can control the fermentation process without on-site inspection. It is achieved that the optimal working state can be guaranteed without on-site inspection or on-site adjustment of working parameters, reducing the workload of the staff and improving work efficiency.

[0050] During the monitoring process, the working current of the pressure monitoring module will be affected by the temperature in the fermentation tank. Therefore, the voltage adjustment module can adjust the working voltage of the pressure monitoring module according to the current of the pressure monitoring module to ensure the stability of the pressure sensor and avoid the problem of affecting the quality of fruit wine due to the inability to accurately discharge carbon dioxide in the fermentation tank.

[0051] like Figure 2 As shown, this embodiment also includes a voltage stabilizing module, a temperature monitoring module and a valve control module; the first end of the voltage stabilizing module is connected to the power supply, and the second end of the voltage stabilizing module is connected to the temperature monitoring module; the temperature monitoring module is used to monitor the temperature in the fermentation tank; the processor is configured to control the valve control module according to the temperature in the fermentation tank.

[0052] The fermentation process of fruit wine is a complex biochemical reaction process, in which temperature plays a vital role. The temperature of the fermentation tank directly affects the growth and metabolic activity of yeast and the production of various flavor substances in fruit wine. Too high a temperature may cause the yeast to die prematurely, while too low a temperature may cause the yeast to enter a dormant state, affecting the fermentation process. In addition, temperature is closely related to the formation of characteristics such as color, aroma and taste in fruit wine.

[0053] In this embodiment, the temperature monitoring module is used to monitor the temperature changes in the fermentation tank, and convert the temperature signal in the fermentation tank into an electrical signal and send it to the processor. When the temperature in the fermentation tank exceeds or is lower than the set value, the processor sends a control instruction to the valve control module. The valve control module is used to control the temperature in the fermentation tank. The valve control module ensures that the temperature in the fermentation tank remains within the set range by adjusting the temperature control valve.

[0054] The voltage stabilizing module is used to provide a stable operating voltage for the temperature monitoring module to ensure the stability of temperature monitoring.

[0055] During the fermentation process, the temperature in the fermentation tank is one of the key factors affecting the growth and metabolism of microorganisms. As the fermentation time changes, the metabolic activity of the microorganisms will generate heat, causing the temperature in the tank to rise. If the temperature is not properly controlled, it may have a negative impact on the growth of the microorganisms and even cause the fermentation process to fail. Therefore, the temperature control in the fermentation tank needs to be appropriately adjusted according to the changes in the fermentation time. Specifically, in the early stage of fermentation, the growth rate of the microorganisms is slow and the heat generated by metabolic activities is less. At this time, a relatively low temperature can be set to promote the adaptation and growth of the microorganisms. As the fermentation proceeds, the growth rate of the microorganisms accelerates, the metabolic activity increases, and the heat generated increases. At this time, the temperature needs to be gradually increased to maintain a suitable metabolic environment. Therefore, in this embodiment, the processor can automatically adjust the temperature according to the fermentation time.

[0056] like Figure 3 As shown, in this embodiment, a remote monitoring type intelligent fermentation controller further includes an alcohol monitoring module;

[0057] The first end of the alcohol monitoring module is connected to the second end of the voltage stabilizing module, and the second end of the alcohol monitoring module is connected to the processor.

[0058] The alcohol concentration in the fruit wine fermentation tank is crucial for controlling the fermentation process and evaluating the quality of the fruit wine. During the fermentation process, the production of alcohol is a direct product of yeast metabolism, and its concentration changes reflect the progress of fermentation and possible problems. Therefore, accurate monitoring of alcohol concentration helps to optimize the production process and improve the quality and consistency of fruit wine.

[0059] In this embodiment, the alcohol monitoring module is used to monitor the alcohol concentration of fruit wine during the fermentation process, convert the alcohol concentration signal into an electrical signal and send it to the processor. The voltage stabilizing module also provides a stable working voltage for the alcohol monitoring module. The staff can check the alcohol concentration value in the fermentation tank through the terminal, and can also check the temperature value of the fermentation tank through the terminal.

[0060] like Figure 3 As shown, a remote monitoring type intelligent fermentation controller in this embodiment also includes an alarm circuit and a timing module; the alarm circuit and the timing module are both connected to the processor.

[0061] In this embodiment, when the temperature in the fermentation tank exceeds the set value, the temperature in the fermentation tank can be adjusted by controlling the valve control module. The valve control module is used to adjust the temperature regulating valve. During this process, the valve control module may fail, resulting in the temperature in the fermentation tank exceeding the set value. The temperature cannot be adjusted in time, thereby affecting the fermentation quality of the fruit wine.

[0062] To this end, this embodiment adds a timing module and an alarm module. When the temperature in the fermentation tank exceeds the set value, the processor sends a timing instruction to the timing module, and the timing module starts timing. If the temperature in the fermentation tank does not return to the normal value within the set time, the processor sends an alarm instruction to the alarm module, and the alarm module is used to send an alarm signal to notify the on-site staff. At the same time, the processor will also send the alarm signal to the terminal through the communication module. When the staff is not on-site, a remote alarm can be realized to remind the staff to take corresponding measures in time, thereby ensuring the fermentation quality of the fruit wine.

[0063] In this embodiment, when the operation of the intelligent fermentation controller is abnormal or the working parameters cannot meet the fermentation requirements on site, the abnormal situation of the intelligent fermentation controller can be checked or the working parameters can be modified through the terminal, and the historical records can be queried. The operation is simple and easy to understand. The equipment can be guaranteed to be in the best working state without on-site inspection or on-site adjustment of working parameters, which reduces the maintenance cost of the equipment and the workload of the maintenance personnel and improves the work efficiency.

[0064] At the same time, various monitoring data during the fermentation process can be stored and archived for later analysis or tracing of historical data.

[0065] Furthermore, a remote monitoring type intelligent fermentation controller in this embodiment also includes a display screen, which is used for displaying on-site data.

[0066] like Figure 4 As shown, in this embodiment, the pressure monitoring unit includes an optocoupler U3, a resistor R1, a capacitor C1, a transistor T1, a resistor R2, a switch tube T2, a capacitor C2, a pressure sensor U1 and a resistor R5; the first end of the switch tube T2 is connected to the VCC power supply, the second end of the switch tube T2 is grounded through the capacitor C2, the second end of the switch tube T2 is connected to the power supply end of the pressure sensor U1, the ground end of the pressure sensor U1 is grounded through the resistor R5, and the output end of the pressure sensor U1 is connected to the processor; the ground end of the pressure sensor U1 is connected to the first input end of the optocoupler U3, the second input end of the optocoupler U3 is grounded, the first output end of the optocoupler U3 is connected to the VCC power supply, the second output end of the optocoupler U3 is connected to the first end of the resistor R1, the second end of the resistor R1 is grounded through the capacitor C1, the second end of the resistor R1 is connected to the control end of the transistor T1, the first end of the transistor T1 is connected to the VCC power supply, the second end of the transistor T1 is grounded through the resistor R2, and the second end of the transistor T1 is connected to the control end of the switch tube T2.

[0067] In this embodiment, the specific working principle of the pressure monitoring unit is as follows: when working, the optocoupler U3 is turned on, and the VCC power supply charges the capacitor C1 through the phototransistor and the resistor R1 inside the optocoupler U3. When the charging voltage of the capacitor C1 reaches the turn-on voltage of the transistor T1, the transistor T1 is turned on, the capacitor C1 starts to discharge, and a voltage is generated on the resistor R2. The voltage on the resistor R2 slowly decreases with the discharge of the capacitor C1. When the voltage on the capacitor C1 is lower than the valley voltage of the transistor T1, the transistor T1 is turned off, the voltage on the resistor R2 disappears, and then the capacitor C1 starts to charge again, thereby forming a cycle. In this way, a sawtooth wave signal is generated on the resistor R2. The frequency of the sawtooth wave signal generated on the resistor R2 can be changed by changing the resistance value of the resistor R1. The sawtooth wave signal is added to the control end of the switch tube T2. When the amplitude of the sawtooth wave is greater than the turn-on voltage of the switch tube T2, the switch tube T2 is turned on. In this way, the VCC power supply is added to the power supply end of the pressure sensor U1 through the switch tube T2, and the pressure sensor U1 starts to work. A voltage is generated on the resistor R5 and added to the two ends of the light-emitting diode inside the optocoupler U3. The pressure sensor U1 is used to monitor the pressure in the fermentation tank, and then converts the pressure signal into an electrical signal and sends it to the processor.

[0068] During the fermentation of fruit wine, the temperature in the fermentation tank changes, which causes the internal resistance of the pressure sensor U1 to change. When the voltage remains unchanged, the current flowing through the pressure sensor U1 changes, so the voltage on the resistor R5 changes. When the voltage on the resistor R5 changes, the luminous power of the light-emitting diode inside the optocoupler U3 will change, which causes the resistance of the phototransistor inside the optocoupler U3 to change. Since the phototransistor inside the optocoupler U3 and the resistor R1 are connected in series, when the resistance of the phototransistor inside the optocoupler U3 changes, the charging and discharging time of the capacitor C1 will change, thereby changing the frequency of the sawtooth wave on the resistor R2. That is, the on and off time of the switch tube T2 is changed, which also changes the working voltage of the pressure sensor U1, and then changes the current flowing through the pressure sensor U1. Therefore, the pressure monitoring unit in this embodiment can automatically adjust the working voltage of the pressure sensor U1 according to the change of the environment to ensure the stability of the operation of the pressure sensor U1.

[0069] like Figure 4 As shown, the pressure monitoring unit in this embodiment also includes a resistor R4, a variable resistor RP1, a voltage regulator tube D1 and an operational amplifier U2; the first end of the resistor R4 is connected to the second end of the transistor T1, the second end of the resistor R4 is connected to the non-inverting input end of the operational amplifier U2, the first end of the variable resistor RP1 is connected to the VCC power supply, the second end of the variable resistor RP1 is grounded, the sliding end of the variable resistor RP1 is connected to the cathode of the voltage regulator tube D1, the anode of the voltage regulator tube D1 is grounded, the sliding end of the variable resistor RP1 is connected to the inverting input end of the operational amplifier U2, and the output end of the operational amplifier U2 is connected to the control end of the switch tube T2.

[0070] In this embodiment, a sawtooth wave is used as a switch signal to control the on and off of the switch tube T2, which has the advantages of low manufacturing cost, simple circuit and convenient use, but there are also some disadvantages in practical applications, such as the switching frequency is not fixed, it is easy to generate noise, etc., thus affecting the working stability of the switch tube T2.

[0071] To this end, the present embodiment adds a waveform conversion circuit, which is composed of a resistor R4, a variable resistor RP1, a voltage regulator D1 and an operational amplifier U2. The waveform conversion circuit is used to convert the sawtooth wave generated on the resistor R2 into a rectangular wave output. Specifically, the variable resistor RP1 and the voltage regulator D1 constitute a voltage stabilizing circuit to provide a stable reference voltage for the inverting input terminal of the operational amplifier U2. The operational amplifier U2 constitutes a comparator. The in-phase input terminal of the operational amplifier U2 is used to receive the sawtooth wave signal on the resistor R2. When the amplitude of the sawtooth wave signal is greater than the reference voltage of the inverting input terminal of the operational amplifier U2, the operational amplifier U2 outputs a high level. When the amplitude of the sawtooth wave signal is lower than the reference voltage of the inverting input terminal of the operational amplifier U2, the operational amplifier U2 outputs a low level. When the operational amplifier U2 outputs a low level, the switch tube T2 is turned off. When the operational amplifier U2 outputs a high level, the switch tube T2 is turned on. The frequency of the sawtooth wave signal changes, and the frequency of the rectangular wave signal output by the operational amplifier U2 also changes.

[0072] like Figure 4 As shown, the pressure monitoring unit in this embodiment also includes a resistor R6, a resistor R7, an operational amplifier U4 and a resistor R8; the first output end of the pressure sensor U1 is connected to the inverting input end of the operational amplifier U4 through the resistor R6, the second output end of the operational amplifier U1 is connected to the non-inverting input end of the operational amplifier U4 through the resistor R7, the output end of the operational amplifier U4 is connected to the inverting input end of the operational amplifier U4 through the resistor R8, and the output end of the operational amplifier U4 is connected to the processor.

[0073] In this embodiment, the electrical signal output by the pressure sensor U1 is relatively small, and the processor cannot effectively monitor the voltage signal output by the pressure sensor U1. For this reason, in this embodiment, an amplification circuit is added between the output end of the pressure sensor U1 and the processor. The amplification circuit is composed of a resistor R6, a resistor R7, an operational amplifier U4 and a resistor R8, and is used to amplify the electrical signal output by the pressure sensor U1, and finally send the amplified electrical signal to the processor.
