Technical Field

[0001] This utility model relates to the field of brewing equipment technology, specifically a multi-channel brewing condenser system. Background Technology

[0002] In the baijiu brewing process, the condenser is the core equipment in the distillation process. Its cooling efficiency directly affects the retention rate of flavor substances in the liquor. Currently, the industry generally adopts a configuration mode of multiple condensers connected in parallel with a single cooling tower. A fixed cooling water flow rate is usually used. This not only cannot effectively adapt to the working requirements of different condensers, but also cannot ensure precise control of the liquor output temperature. This fixed cooling water flow rate management method makes it difficult to achieve precise temperature control during the brewing process, thereby affecting the quality of the liquor and production efficiency.

[0003] Therefore, there is an urgent need to design a multi-channel brewing condenser system that can accurately control the flow rate of different condensation channels, improve the condensation efficiency of the brewing process, and ensure the quality of the brewed wine. Utility Model Content

[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 The present invention provides a multi-channel brewing condenser system, comprising a condensate main pipe 1 and a water supply pump 2. The inlet of the condensate main pipe 1 is connected to the outlet of the cooling tower via the water supply pump 2. The outlet of the condensate main pipe 1 is connected to the inlet of multiple inlet branch pipes 6 via a distributor. The outlet of each inlet branch pipe 6 is connected to the cooling water inlet of the corresponding condenser. The outlet of each condenser is connected to the return end of the cooling tower via a return water pipe. The distributor is a tee pipe or a multi-way distributor. A temperature sensor 3 is installed at the outlet of the condenser. The temperature sensor 3 is a contact or non-contact temperature probe. In this application, a contact temperature sensor 3, specifically a PT100 platinum resistance temperature sensor, is installed at the outlet of the condenser. The inlet branch pipe 6 is equipped with an electric regulating valve 4 for independently adjusting the cooling water flow rate of the corresponding condenser, and a manual bypass valve (not shown in the figure) is installed in parallel on each branch. The manual bypass valve is normally closed. When the controller or the electric regulating valve 4 fails, the operator can manually open the bypass valve to maintain the basic condensate flow rate at a preset opening degree. The electric regulating valve 4 in this application is a DN25 electric ball valve with a CV value of 1.8 and a response time of ≤2s. The electric regulating valve 4 has multiple opening degree values. Both the electric regulating valve 4 and the temperature sensor 3 are connected to the controller. The controller can be a PLC controller, which is configured to independently output PWM signals to the electric regulating valves 4 of each branch to adjust their opening degree based on the wine outlet temperature signals detected by each temperature sensor 3. That is, when the wine outlet temperature of the condenser is higher than the set threshold, the controller increases the opening degree of the electric regulating valve 4 to increase the cooling water flow; otherwise, it decreases the opening degree to achieve closed-loop temperature control. The controller of this application also has a built-in watchdog circuit, which automatically locks the opening degree of the electric regulating valve 4 to a safe value when an abnormal temperature signal is detected to avoid sudden changes in flow leading to uncontrolled wine temperature.

[0021] This application forms a closed-loop control system by combining an electric regulating valve 4 with a temperature sensor 3 and a controller. The opening of the electric regulating valve 4 can be automatically adjusted according to the real-time temperature of the outlet, thereby achieving dynamic control of the condensate flow rate. It can adjust the cooling water flow rate in real time according to the actual condensation needs without interrupting the brewing process. This not only improves condensation efficiency but also ensures more precise temperature control at the outlet, which helps to improve the quality of the wine and production efficiency. It can effectively solve the problem that traditional condensation configuration modes are difficult to achieve precise temperature control, thus affecting the quality of the wine and production efficiency.

[0022] Example 2

[0023] Based on the above embodiments, this embodiment aims to suppress pipeline vibration caused by the operation of the water supply pump 2, such as... Figure 2-3The condensate main pipe 1 between the outlet of the water supply pump 2 and the distributor is provided with a shock-absorbing seat 5 to suppress hydraulic shock vibration. The shock-absorbing seat 5 includes a fixed base 51 and an elastic support component 52 disposed on the fixed base 51. The condensate main pipe 1 is fixedly installed on the elastic support component 52. The elastic support assembly 52 includes an annular support 521 sleeved on the outer wall of the condensate main pipe 1. The annular support 521 is 20mm thick, and its inner diameter matches the pipe diameter. The material of the annular support 521 is a rubber composite material with a compression permanent deformation rate of ≤15%. The elastic support assembly 52 also includes dampers 522 symmetrically distributed on both sides of the condensate main pipe 1. In this application, hydraulic dampers are used. The axis of the damper 522 is parallel to the axis of the condensate main pipe 1. Both ends are connected to the base and the annular support 521 by ball joints. The upper end is connected to the annular support 521, and the lower end is connected to the fixed base 51. The vibration damping seat 5 of this application adopts a combination structure of elastic support and damper 522, which mainly suppresses the axial vibration of the condensate main pipe 1. The symmetrically arranged dampers 522 absorb the water hammer impact energy generated by the start and stop of the water pump through axial compression / tension movement. The annular support 521 attenuates high-frequency mechanical vibration through radial elastic deformation.

[0024] This application refers to GB / T19873.2-2019 to conduct vibration suppression tests on the condensate main pipe 1;

[0025] Vibration type Amplitude without damping seat Amplitude with damping seat Attenuation rate Axial vibration 1.2mm 0.15mm 87.5% radial vibration 0.8mm 0.32mm 60%

[0026] Table 1 Vibration Suppression Test Table

[0027] Operating principle: When the water supply pump 2 starts or stops, or when valve adjustment causes axial water hammer impact, the hydraulic damper arranged coaxially on the condensate main pipe 1 generates a reverse damping force, converting most of the impact kinetic energy into heat energy for dissipation. At the same time, the annular support 521 sleeved on the pipe wall absorbs high-frequency mechanical vibration through radial compression deformation. The dual effect reduces the amplitude of axial vibration in the pipeline. That is, when water flows and impacts, the front damper is compressed and the rear damper is stretched, jointly consuming the impact energy. The two dampers act like "hydraulic springs" to resist pipeline displacement at the same time, completely eliminating pipeline flutter caused by water supply jerking, and no additional power source is required. It can effectively suppress axial vibration energy and solve the pipeline flutter problem caused by water supply pump 2 jerking.

[0028] Based on the above embodiments, the applicant compared the multi-channel brewing condenser system prepared in this application with an existing parallel condenser under the same conditions of distillery, same batch of sorghum, and completely consistent distillation process parameters. The standard for measuring the outlet temperature was determined by continuously sampling 30 batches according to GB / T11860 "Analysis Methods for Baijiu" with a standard deviation of ±0.5℃. The response time was recorded when the sensor reading reached 79.7℃ as the liquor temperature jumped from 70℃ to 80℃. The traditional parallel condenser 3 showed an outlet temperature fluctuation of ±0.98℃, a thermal response time of 2.4s, and a premium liquor yield of 68±3%. The multi-channel brewing condenser system 3 of this application showed an outlet temperature fluctuation of ±0.12℃, a thermal response time of 0.28s, and a premium liquor yield of 79±2%. Therefore, it can be concluded that… The multi-channel brewing condenser system provided in this application forms a closed-loop control system through the cooperation of an electric regulating valve 4, a temperature sensor 3, and a PLC controller. Combined with a shock-absorbing base 5, it mitigates pipeline vibration caused by hydraulic shock during the operation of the water supply pump 2, while ensuring consistent temperature control across all condensers under varying operating conditions. The system can automatically adjust the opening of the electric regulating valve 4 based on the real-time temperature at the outlet, thereby achieving dynamic control of the condensate flow rate. This allows for real-time adjustment of the cooling water flow rate according to actual condensation needs without interrupting the brewing process. This not only improves condensation efficiency but also ensures more precise temperature control at the outlet, contributing to improved product quality and production efficiency. It effectively solves the problem of traditional condenser configurations failing to achieve precise temperature control, thus affecting product quality and production efficiency.
