Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, specifically to a condenser with alcohol content detection function. Background Technology

[0002] In traditional winemaking, conventional condensers lack integrated detection capabilities. Alcohol content determination typically relies on the winemaker's experience to take samples periodically, which are then sent to a testing device to determine the percentage of alcohol in the wine. This approach has several problems: different winemakers have varying experience and sampling times, leading to significant differences in alcohol concentration in the collected samples, thus affecting the final wine quality. Especially for novice winemakers, lack of experience can result in sampling too early or too late, wasting wine and impacting winemaking efficiency.

[0003] Therefore, it is particularly important to develop a condenser that is easy to operate and can accurately detect alcohol content. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned technical difficulties and provide a condenser for detecting alcohol content, enabling in-situ rapid detection of alcohol content, which can significantly improve brewing efficiency and product quality stability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a condenser with alcohol content detection, comprising a condenser body and an outlet pipe, wherein the outlet pipe is connected to a detection chamber via a detection valve, the bottom of the detection chamber is provided with a drain valve and an auxiliary outlet with a conical nozzle structure, the top of the detection chamber is provided with an openable and closable sealing cover, and a mechanical alcohol meter is built in; the side wall of the detection chamber is provided with an infrared transmission observation window, and an infrared sensor module is installed on the outside; the sealing cover integrates a temperature sensor, and the probe extends to the geometric center of the detection chamber.

[0006] Furthermore, the side wall of the detection cavity is provided with a cleaning port, which is connected to a steam source through a solenoid valve. The axis of the cleaning port is set at an angle of 45±5° with the normal of the observation window, and the inner end of the cleaning port is a fan-shaped nozzle with a coverage angle of ≥120°.

[0007] Furthermore, the outer wall of the cavity is covered with a jacketed water-cooling jacket. The inlet of the jacketed water-cooling jacket is connected to the condenser cooling water inlet pipe through a three-way valve, and the outlet of the jacketed water-cooling jacket is connected to the condenser cooling water outlet pipe through an electric regulating valve. The jacketed water-cooling jacket is equipped with spiral guide vanes.

[0008] Furthermore, a 3mm heat-insulating air layer is maintained between the jacketed water-cooling jacket and the outer wall of the detection cavity, and the electric regulating valve is driven by a PID controller.

[0009] Furthermore, the infrared sensor module includes a near-infrared light source with a wavelength range of 1400-2500nm, an InGaAs detector, and the optical path is set at a 15° angle to the normal of the observation window.

[0010] Furthermore, the flow velocity at the throat of the fan-shaped nozzle of the cleaning port is ≥15m / s, and the steam pressure ranges from 0.6 to 0.8MPa.

[0011] Furthermore, the throat diameter ratio of the conical nozzle at the auxiliary outlet is 1:3, and the angle between the drain valve and the axis of the auxiliary outlet is ≤30°.

[0012] The condenser with alcohol content detection provided by this utility model has the following beneficial effects:

This significantly improves brewing efficiency and product quality stability, and effectively solves the problems of cumbersome traditional alcohol content detection methods that rely on experience and have large sampling errors.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] Example 1

[0020] like Figure 1-3The present invention provides a condenser with alcohol content detection, comprising a condenser body 1 and an outlet pipe 2. The outlet pipe 2 is connected to a detection chamber 4 via a detection valve 3. The detection chamber 4 is connected to the detection valve 3 of the outlet pipe 2 via a flange interface. The valve is a stainless steel butterfly valve to ensure sealing. The detection chamber 4 is designed to be 300-500ml to ensure that the alcohol completely submerges the alcohol meter and the liquid level is stable.

[0021] The bottom of the detection chamber 4 is equipped with a drain valve 5 and an auxiliary outlet 6 with a conical nozzle structure. To improve the accuracy of the detection and ensure that there is no residual wine from the previous test in the detection chamber 4, the throat diameter ratio of the conical nozzle of the auxiliary outlet 6 is 1:3, and the angle between the drain valve 5 and the axis of the auxiliary outlet is ≤30°. The principle of fluid entrainment is used to generate local negative pressure. That is, when the auxiliary outlet 6 is opened, the flow velocity of the residual wine increases as it flows through the tapered section of the conical nozzle. According to Bernoulli's principle, the increase in flow velocity leads to a decrease in static pressure in the throat area of ​​the nozzle, forming a local negative pressure zone. This negative pressure is transmitted to the lowest point of the detection chamber 4 through the outlet pipe, which works synergistically with the gravity discharge of the drain valve 5 to more thoroughly draw out the residual wine at the lowest point of the detection chamber 4, ensuring that there is no residue that affects the accuracy of the next test. The detection cavity 4 is equipped with an openable and closable sealing cover 7 at the top, and a mechanical alcohol meter 8 is built in. The mechanical alcohol meter 8 is vertically suspended in the center of the cavity. The side wall of the detection cavity 4 is equipped with an infrared transmission observation window 9. The infrared transmission observation window 9 is made of ZnSe crystal material and has a diamond film with a thickness of 2μm on its surface. A non-contact infrared sensor module 10 is installed on the outside. The infrared sensor module 10 includes a near-infrared light source with a wavelength range of 1400-2500nm, an InGaAs detector, and the optical path is set at a 15° angle with the normal of the observation window to ensure that the incident angle is less than the critical angle to avoid specular reflection, so as to achieve the best balance between emission suppression and transmittance. The sealing cover 7 integrates a temperature sensor 11, and the probe extends to the geometric center of the detection cavity 4.

[0022] Example 2

[0023] Based on the above embodiments, this embodiment, in order to improve the accuracy of alcohol content detection, also provides a cleaning port 12 on the side wall of the detection chamber 4. The cleaning port 12 is connected to a steam source through a solenoid valve. The axis of the cleaning port 12 is set at an angle of 45±5° with the normal of the observation window. The inner end of the cleaning port 12 is a fan-shaped nozzle with a throat diameter ≤2mm and a coverage angle ≥120°. The flow velocity at the throat of the fan-shaped nozzle of the cleaning port 12 is ≥15m / s. The steam pressure range is 0.6-0.8MPa. When the steam pressure is 0.7MPa, the flow velocity is ≥18.4m / s. The detection chamber 4 is cleaned by the steam source, so that no alcohol from the previous test adheres to the detection chamber 4 during each test, thereby improving the detection accuracy of the detection chamber 4 for the corresponding alcohol content.

[0024] Example 3

[0025] Based on the above embodiments, this application improves the stability of alcohol content detection by covering the outer wall of the detection cavity 4 with a jacketed water-cooled jacket 13. The inlet of the jacketed water-cooled jacket 13 is connected to the condenser cooling water inlet pipe via a three-way valve, and the outlet of the jacketed water-cooled jacket 13 is connected to the condenser cooling water outlet pipe via an electric regulating valve. A spiral guide vane is provided inside the jacketed water-cooled jacket 13. A 3mm heat-insulating air layer 14 is maintained between the jacketed water-cooled jacket 13 and the outer wall of the detection cavity 4. The electric regulating valve is driven by a PID controller, and the temperature sensor 11 monitors the temperature data and inputs it to the PID controller in real time. When the wall temperature is >50℃, the electric regulating valve remains closed; when the wall temperature is ≤45℃, the PID controller slowly opens the valve according to the step response curve. The electric regulating valve is dynamically adjusted by the PID controller to stabilize the alcohol temperature at 25±0.3℃. This application effectively reduces the impact of ambient temperature fluctuations on the alcohol temperature during detection by using the jacketed water-cooled jacket 13, thus improving the stability of the alcohol content reading.

[0026] Example 4

[0027] Based on the above embodiments, the outer wall of the detection cavity 4 described in this application is fixedly provided with an alcohol temperature conversion reference table, and the top of the detection cavity 4 is provided with an LCD display screen for displaying infrared detection results. The LCD display screen and the mechanical alcohol meter 8 are arranged at the same viewing angle, which facilitates data comparison. When the LCD display screen malfunctions, dynamic correction is performed in conjunction with the reference table during the detection and reading of alcohol content, which facilitates the operator to quickly look up the table on-site for temperature correction, reduces search time, and improves detection efficiency. The LCD display screen and alcohol temperature conversion reference table position scheme provided in this application can be replaced by wireless transmission or other methods by those skilled in the art.

[0028] The operational process of this application includes a detection stage, a drainage stage, and a cleaning stage;

[0029] Testing phase:

[0030] Open the detection valve 3, and the liquid flows into the detection chamber 4 until the liquid surface reaches the center line of the infrared transmission observation window 9, where the mechanical alcohol meter 8 is suspended.

[0031] Close the detection valve 3, let it stand for 90±5 seconds to stabilize the wine, read the alcohol content through the infrared sensor module 10, and simultaneously record the center temperature data of the thermometer through the temperature sensor 11.

[0032] Drainage phase:

[0033] First, open the drain valve 5 to drain the main liquid. Then, open the auxiliary drain outlet 6. The conical nozzle generates a negative pressure of ≥9.8kPa to suck out the residual liquid.

[0034] Cleaning phase:

[0035] First, close the electric regulating valve connected to the condenser cooling water outlet pipe, open the drain valve 5 and auxiliary drain outlet 6, and open the steam valve of cleaning port 12 after a 1-second delay. Use high-temperature steam to perform turbulent flushing on the detection chamber. After 5 seconds of pipe preheating, perform effective flushing for 20 seconds. Close the drain valve 5 and auxiliary drain outlet 6 3 seconds before the end of cleaning. Use the residual steam pressure in the pipe to maintain turbulent flushing for 3 seconds. After cleaning, close the steam valve. The temperature sensor monitors the wall temperature in real time. Allow the water to cool naturally until the wall temperature is ≤45℃. The PID slowly restarts the water cooling system at a slope of 0.5℃ / s.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
