Description

Technical Field

[0001] This application relates to the field of biotechnology, and in particular to a multi-point temperature measurement device for a fermenter. Background Technology

[0002] During wine fermentation, the difference in thermal conductivity between the pomace cap and the liquid area within the fermentation tank can easily create a temperature gradient, leading to uneven fermentation rates and affecting wine quality. Traditional fermentation tanks often use single-point temperature sensors, which can only monitor the temperature at a fixed location within the tank. This fails to monitor the temperature at different locations during fermentation and cannot reflect the overall temperature distribution within the tank. Existing temperature control methods mostly involve overall heating or cooling, making it difficult to precisely adjust for localized temperature anomalies. This can lead to energy waste and exacerbate heterogeneity within the tank, negatively impacting wine quality. Utility Model Content

The device is equipped with a steel pipe, and a temperature sensor assembly is installed inside the steel pipe. The temperature sensor assembly includes multiple temperature sensor units. The multiple temperature sensor units, which are distributed axially, monitor the temperature at different locations inside the wine fermentation tank. By monitoring the temperature, the corresponding heat exchange coils are linked to independently regulate the temperature of the tank. Cooling and heating are performed through a refrigerant tank and a heat pump mechanism, thereby controlling the local temperature inside the tank, improving the temperature uniformity inside the tank during fermentation, ensuring the quality of the wine, and improving energy utilization.

[0004] This application provides a multi-point temperature measurement device for a fermenter, comprising: a tank body and a heat pump mechanism. A feed inlet is located at the top of the tank body, and a cover is provided on the feed inlet. A steel pipe is welded through a circular hole at the top of the tank body, with one end of the steel pipe extending into the tank body. A temperature sensor assembly is axially mounted inside the steel pipe. The temperature sensor assembly includes a support rod and multiple temperature sensor units, which are equidistantly distributed along the axial direction of the support rod. Multiple heat exchange coils are provided on the outer wall of the tank body, the number of which is equal to the number of temperature sensor units and corresponds one-to-one along the axial direction. Each heat exchange coil is equipped with one inlet and one outlet. Each heat exchange coil is equipped with a solenoid valve group at both its inlet and outlet. The inlets of multiple heat exchange coils are connected to the same inlet pipe. The inlet pipe is equipped with a circulating pump and a flow regulating valve. The inlet pipe is connected to a heat pump mechanism, which is connected to a refrigerant tank. The outlets of multiple heat exchange coils are connected to the same outlet pipe, which is connected to the heat pump mechanism. The heat pump mechanism includes a compressor, a four-way reversing valve, a condenser, an expansion valve, and an evaporator. A discharge port is provided at the bottom of the tank, and a cover is provided on the discharge port. Four support legs are welded to the bottom of the tank.

[0005] The tank and heat pump mechanism are connected to an external controller. The temperature sensor assembly, solenoid valve group, compressor, condenser, four-way reversing valve, evaporator, circulating pump, and flow regulating valve are electrically connected to the controller.

[0006] Furthermore, silicone oil is added inside the steel pipe.

[0011] As can be seen from the above technical solution, this application provides a multi-point temperature measurement device for a fermentation tank, including: a tank body and a heat pump mechanism. A feed inlet is provided at the top of the tank body, and a cover is provided on the feed inlet. The cover is opened, and the material to be fermented is fed into the tank through the feed inlet. Then the cover is closed. A steel pipe is welded through a circular hole at the top of the tank body, with one end of the steel pipe extending into the tank body. A temperature sensor assembly is installed axially inside the steel pipe. The temperature sensor assembly includes a support rod and multiple temperature sensor units, which are equidistantly distributed along the axial direction of the support rod. The temperature sensor assembly is inserted into the steel pipe and fixed using a lower and upper connection port. The multiple temperature sensor units monitor the temperature at different locations within the wine fermentation tank, allowing for timely adjustments to the fermentation tank temperature. The internal temperature is controlled to prevent excessively high or low temperatures from affecting the quality of the wine. Multiple heat exchange coils are installed on the outer wall of the tank, with the number of coils equal to the number of temperature sensor units and corresponding axially. Each heat exchange coil has an inlet and an outlet, and each inlet and outlet is equipped with a solenoid valve assembly. The solenoid valve assembly contains two solenoid valves, installed at the inlet and outlet of the heat exchange coil respectively, and both valves open or close simultaneously to facilitate refrigerant flow and temperature control. When a temperature sensor unit detects that the temperature in a certain area of ​​the fermentation tank exceeds a threshold, both the inlet and outlet solenoid valve assemblies on the corresponding heat exchange coil open. The temperature sensor unit sends an electrical signal to the controller, which then sends... An electrical signal is sent to the heat pump mechanism, which then starts and activates the refrigerant to achieve a cooling mode. The cooled refrigerant enters the heat exchange coil to absorb heat, thereby lowering the temperature of that area, and is then output back to the heat pump mechanism for refrigeration. When the temperature sensor unit detects that the temperature of a certain area inside the fermentation tank is below a threshold, the controller controls the four-way reversing valve of the heat pump mechanism to switch the valve port connection status, thereby switching the refrigerant flow to achieve a heating mode. The refrigerant enters the heat exchange coil to release heat, raising the temperature of that area, and is then output back to the heat pump mechanism for refrigeration. Through the heat pump mechanism's heating or cooling of the refrigerant, and by using the temperature sensor unit to monitor the temperature and link it to the corresponding heat exchange coil, the heat pump mechanism independently regulates the temperature of specific areas within the tank, improving energy efficiency. The four-way reversing valve controls the refrigerant flow. The flow direction of the refrigerant regulates the temperature of the fermenting wine inside the tank, adapting to the fermentation requirements and ensuring wine quality. Multiple heat exchange coils have their inlets connected to the same inlet pipe, which is equipped with a circulation pump and a flow control valve. The circulation pump delivers refrigerant, and the flow control valve is manually adjusted to control the flow rate of refrigerant entering the heat exchange coils through the inlet pipe. The inlet pipe connects to a heat pump mechanism, which is connected to a refrigerant tank. The outlets of multiple heat exchange coils are connected to the same outlet pipe, which is connected to the heat pump mechanism. When the controller receives an electrical signal from the temperature sensor unit indicating that refrigerant needs to be introduced into the heat exchange coils to regulate the temperature inside the fermentation tank, the controller sends an electrical signal to the solenoid valve, heat pump mechanism, circulation pump, and solenoid valve assembly on the pipe connected to the refrigerant tank. Upon receiving the electrical signal, each component opens.Refrigerant enters the heat pump mechanism for cooling or heating, and then, through the action of a circulating pump, is transported from the inlet pipe to the heat exchange coil. After heat exchange, the refrigerant is discharged through the outlet pipe back to the heat pump mechanism for further cooling or heating, forming a refrigerant circulation loop. The refrigerant used is ethylene glycol. The heat pump mechanism includes a compressor, a four-way reversing valve, a condenser, an expansion valve, and an evaporator. All components of the heat pump mechanism are interconnected to heat or cool the refrigerant. Specifically, the heat pump mechanism uses a PHNIX industrial-grade air source heat pump, model FPH-80WA, with a discharge port at the bottom of the tank. The tank has a second cover at the opening. After fermentation, the second cover can be opened to discharge the material. Four support legs are welded to the bottom of the tank, providing structural support. The tank and heat pump mechanism are connected to an external controller. The temperature sensor assembly, solenoid valve group, heat pump mechanism, circulation pump, and flow regulating valve are all electrically connected to the controller. The controller is preferably a standard PLC from JunChuang Automation Technology Co., Ltd., model JS-68T-D. The controller can control the electrically connected components to receive and act on corresponding commands, thereby regulating the temperature of the tank.

[0025] Example 1:

[0026] A multi-point temperature measurement device for a fermentation tank includes: a tank body 1 and a heat pump mechanism 12. The top of the tank body 1 has a feed inlet, and a cover is provided on the feed inlet. The cover is opened, and the material to be fermented is fed into the tank body 1 through the feed inlet. The cover is then closed. A steel pipe 3 is welded to a circular hole at the top of the tank body 1, with one end of the steel pipe 3 extending into the tank body 1. A temperature sensor assembly 2 is axially mounted inside the steel pipe 3. The temperature sensor assembly 2 includes a support rod 4 and multiple temperature sensor units 5, which are equidistantly distributed along the axial direction of the support rod 4. The temperature sensor assembly 2 is inserted into the steel pipe 3 and fixed using a lower connection port 31 and an upper connection port 41. The multiple temperature sensor units 5 monitor different locations within the wine fermentation tank 1. The temperature is monitored to control the local temperature within the fermentation tank 1, preventing excessively high or low temperatures from affecting the wine quality. The outer wall of the tank 1 is equipped with multiple heat exchange coils 6, the number of which is equal to the number of temperature sensor units 5 and corresponds axially. Each heat exchange coil 6 has an inlet and an outlet, and each inlet and outlet of a heat exchange coil 6 is equipped with a solenoid valve assembly 7. The solenoid valve assembly 7 contains two solenoid valves, installed at the inlet and outlet of the heat exchange coil 6 respectively, and both solenoid valves open or close simultaneously to facilitate the entry and exit of refrigerant for temperature control. When a temperature sensor unit 5 detects that the temperature in a certain local area within the fermentation tank 1 exceeds a threshold, the solenoid valve assembly at the inlet and outlet of the corresponding heat exchange coil 6 activates. When all seven components are open, temperature sensor unit 5 sends an electrical signal to controller 15, which in turn sends an electrical signal to heat pump mechanism 12. Heat pump mechanism 12 then starts, using it to cool the refrigerant. After cooling, the refrigerant enters heat exchange coil 6 to absorb heat, thus lowering the temperature in that area. The refrigerant is then output to heat pump mechanism 12 for cyclic cooling. When temperature sensor unit 5 detects that the temperature in a certain area of ​​fermentation tank 1 is below a threshold, controller 15 controls the four-way reversing valve of heat pump mechanism 12 to switch the valve port connection state, thereby switching the refrigerant flow direction to achieve heating mode. The refrigerant enters heat exchange coil 6 to release heat, raising the temperature in that area, and is then output to heat pump mechanism 12 for cyclic cooling. The temperature monitored by temperature sensor unit 5 is linked to the corresponding heat exchange coil. Pipe 6 provides independent temperature control for a localized area of ​​tank 1, improving energy efficiency. A heat pump mechanism 12 heats or cools the refrigerant, and a four-way reversing valve controls the refrigerant flow, thereby regulating the temperature of the fermenting wine inside tank 1 to meet fermentation needs and ensure wine quality. The inlets of multiple heat exchange coils 6 are connected to the same inlet pipe 9. The inlet pipe 9 is equipped with a circulation pump 10 and a flow regulating valve 11. The circulation pump 10 delivers refrigerant, and the flow regulating valve 11 is manually adjusted based on the temperature difference to control the flow rate of refrigerant entering the heat exchange coils 6 through the inlet pipe 9, achieving temperature control. The inlet pipe 9 is connected to the heat pump mechanism 12, which is connected to a refrigerant tank 13. The outlets of multiple heat exchange coils 6 are connected to the same outlet pipe 14, which is also connected to the heat pump mechanism 12.When the controller 15 receives an electrical signal from the temperature sensor unit 5 indicating a need to introduce refrigerant into the heat exchange coil 6 to regulate the temperature inside the fermenter, the controller 15 sends an electrical signal to the heat pump mechanism 12, the circulation pump 10, and the solenoid valve assembly 7 connected to the solenoid valve on the pipe of the refrigerant tank 13. Upon receiving the electrical signal, each component opens, allowing the refrigerant to enter the heat pump mechanism 12 for cooling or heating. Then, through the circulation pump 10, the refrigerant is transported to the heat exchange coil 6 via the inlet pipe 9. After heat exchange, the refrigerant is output to the heat pump mechanism 12 via the outlet pipe 14 for further cooling or heating, forming a refrigerant circulation loop. The refrigerant used is ethylene glycol. The heat pump mechanism 12 includes a compressor, a four-way reversing valve, a condenser, an expansion valve, and an evaporator. All components of the heat pump mechanism 12 are connected to heat or cool the refrigerant. Specifically, the heat pump mechanism 12 uses a PHNIX industrial-grade air source heat pump, model FPH-80WA. A discharge port is located at the bottom of the tank 1, and a cover 2 is installed on the discharge port. After fermentation, the cover 2 can be opened to discharge the material. Four support legs 8 are welded to the bottom of the tank 1, providing support for the tank 1.

[0027] Tank 1 is connected to heat pump mechanism 12 by a controller 15. Temperature sensor assembly 2, solenoid valve group 7, heat pump mechanism 12, circulation pump 10, and flow regulating valve 11 are electrically connected to controller 15. Controller 15 is preferably a standard PLC from Junchuang Automation Technology Co., Ltd., model JS-68T-D. Controller 15 can control the components electrically connected to it to receive and act on corresponding instructions, thereby regulating the temperature of tank 1 locally.

[0028] As a preferred embodiment, silicone oil is added inside the steel pipe 3 to enhance temperature conduction.

[0029] In a preferred embodiment, each temperature sensor unit 5 is electrically connected to the solenoid valve group 7 on the heat exchange coil 6 at the corresponding position on the outer wall of the tank 1. When the temperature sensor unit 5 detects that the temperature at a certain position of the tank 1 does not meet the threshold, the temperature sensor unit 5 sends an electrical signal to the solenoid valve group 7 on the heat exchange coil 6 at the corresponding position on the outer wall of the tank 1. The solenoid valve group 7 receives the electrical signal and then opens, thereby allowing the refrigerant to enter and exit the heat exchange coil 6, and achieving local temperature regulation of the tank 1.

[0030] In a preferred embodiment, a lower connection port 31 is welded to the top of the steel pipe 3, and an upper connection port 41 is welded to the side wall of the support rod 4. The upper connection port 41 is sleeved on the outside of the lower connection port 31, and the two connection ports are connected by threads to facilitate the fixing of the temperature sensor assembly 2.

[0031] In a preferred embodiment, the solenoid valve assembly 7 is electrically connected to the controller 15, so that the controller 15 can control the solenoid valve on the tank 1 to open, so that the refrigerant in the refrigerant tank 13 can be introduced into the heat pump mechanism 12 for cooling or heating.
