Abstract
Description
Technical Field
[0001] This utility model relates to the field of beer production technology, and more specifically, to a precooling control system for boiling wort. Background Technology
[0002] Currently, in beer production, it is crucial to minimize the heat load time of boiling wort. Reducing the heat load time minimizes the thermal degradation of flavor compounds in the wort, which is beneficial for nutrient preservation and promotes dominant yeast growth. Rapid pre-cooling of the boiled wort further preserves these flavor compounds, reduces nutrient loss, inhibits the growth of high-temperature microorganisms, and helps the final beer maintain its excellent flavor characteristics.
[0003] Currently, cooling is achieved through a pre-cooling plate; however, due to incomplete wort filtration and the presence of solids after boiling, there is a risk of blockage. Utility Model Content
[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art. The purpose of this utility model is to provide a pre-cooling control system for boiling wort that can reduce clogging.
[0005] The technical solution of this utility model is: a boiling wort precooling control system, including a wort precooling plate, the wort input end of the wort precooling plate being connected to a boiling pot via a wort input pipe, and the wort output end of the wort precooling plate being connected to a sedimentation tank via a wort output pipe. It also includes a wort bypass pipe and a controller. The wort input pipe is sequentially equipped with a wort precooling pump and a wort inlet shut-off valve. The wort output pipe is sequentially equipped with a wort outlet shut-off valve and a wort temperature sensor. One end of the wort bypass pipe is connected to the wort input between the wort precooling pump and the wort inlet shut-off valve. The wort bypass pipe has one end connected to the wort outlet shut-off valve and the wort temperature sensor, and the other end is connected to the wort output pipe. The wort bypass pipe is equipped with a wort bypass valve. The cooling water input end of the wort precooling plate is connected to a purified water source through a purified water input pipe.

The controller is electrically connected to the wort precooling pump, the wort inlet shut-off valve, the wort outlet shut-off valve, the wort temperature sensor, the wort bypass valve, and the purified water frequency converter pump.
[0006] As a further improvement, it also includes a backwash inlet pipe and a backwash outlet pipe. One end of the backwash inlet pipe is connected to the heat recovery tank, and the other end of the backwash inlet pipe is connected to the wort outlet shut-off valve and the wort precooling plate between the wort outlet valve and the wort precooling plate. The backwash inlet pipe is equipped with a backwash pump and a backwash inlet valve in sequence. One end of the backwash outlet pipe is connected to the wort inlet shut-off valve and the wort precooling plate between the wort inlet valve and the wort precooling plate. The backwash outlet pipe is equipped with a backwash outlet valve. The controller is electrically connected to the backwash pump, the backwash inlet valve, and the backwash outlet valve.
[0007] Furthermore, the wort input end of the wort precooling plate is equipped with an input pressure sensor, and the wort output end of the wort precooling plate is equipped with an output pressure sensor. The controller is electrically connected to the input pressure sensor and the output pressure sensor.
[0008] Furthermore, a vibrator is provided at the bottom of the wort precooling plate.

[0014] Beneficial effects
[0015] Compared with the prior art, the advantages of this utility model are as follows:
[0016] This invention addresses the issue of rapid temperature reduction during the boiling process, where the boiled wort requires quick cooling. By passing through a wort pre-cooling plate and being pumped into the settling tank, the wort rapidly cools from 100 degrees Celsius to the required 83 degrees Celsius, ensuring the beer retains its optimal flavor characteristics. Conversely, when rapid temperature reduction is not required or the wort pre-cooling plate becomes clogged (due to incomplete wort filtration and post-boiling solids posing a risk of blockage), the boiled wort is bypassed, ensuring it is successfully pumped into the settling tank within the specified transfer cycle.

Detailed Implementation
[0020] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.
[0021] See Figures 1-2 A wort precooling control system includes a wort precooling plate 1. The wort input end of the wort precooling plate 1 is connected to a boiling pot 3 via a wort input pipe 2, and the wort output end of the wort precooling plate 1 is connected to a sedimentation tank 5 via a wort output pipe 4. The control system also includes a wort bypass pipe 6 and a controller. The wort input pipe 2 is sequentially equipped with a wort precooling pump 7 and a wort inlet shut-off valve 8. The wort output pipe 4 is sequentially equipped with a wort outlet shut-off valve 9 and a wort temperature sensor 10. One end of the wort bypass pipe 6 is connected to the wort input pipe 2 between the wort precooling pump 7 and the wort inlet shut-off valve 8, and the other end of the wort bypass pipe 6 is connected to the wort output pipe 4 between the wort outlet shut-off valve 9 and the wort temperature sensor 10. The wort bypass pipe 6 is equipped with a wort bypass valve 11. The cooling water inlet of the precooling plate 1 is connected to the purified water source 13 through the purified water inlet pipe 12. The purified water source 13 is filled with room temperature purified water (such as tap water or filtered water). The purified water inlet pipe 12 is equipped with a purified water frequency converter pump 14. The cooling water outlet of the wort precooling plate 1 is connected to the heat recovery tank 16 through the purified water outlet pipe 15. The controller is electrically connected to the wort precooling pump 7, the wort inlet shut-off valve 8, the wort outlet shut-off valve 9, the wort temperature sensor 10, the wort bypass valve 11, and the purified water frequency converter pump 14.
[0022] When the process requires rapid cooling of the boiling wort, the wort is pumped into the settling tank 5 through the wort inlet pipe 2 via the wort precooling plate 1. The controller activates the wort precooling pump 7, the wort inlet shut-off valve 8, the wort outlet shut-off valve 9, and the purified water frequency converter pump 14. Based on the detection signal from the wort temperature sensor 10, the controller adjusts the opening of the purified water frequency converter pump 14 (using PID control, a common technique in existing technology). This achieves the goal of rapidly cooling the boiling wort from 100 degrees Celsius to the required 83 degrees Celsius (83 degrees Celsius is determined by the process and is not limited to 83 degrees Celsius; other temperatures are also possible) as it passes through the wort precooling plate 1 and enters the settling tank, ensuring the beer retains its excellent flavor characteristics. The purified water at room temperature reaches 70 degrees Celsius after heat exchange through the wort precooling plate 1 and is then recovered to the heat recovery tank 16 for later use.
[0023] When the process requires that the boiling wort does not require rapid cooling or when the wort precooling plate 1 is clogged (due to incomplete wort filtration and solidification after boiling, there is a risk of clogging), the wort will be pumped into the settling tank through the wort bypass pipe 6, bypassing the wort precooling plate 1. The controller will control the opening of the wort precooling pump 7 and the wort bypass valve 11, and close the wort inlet shut-off valve 8, the wort outlet shut-off valve 9, and the purified water frequency converter pump 14 to ensure that the boiling wort is smoothly pumped into the settling tank within the transfer cycle time.
[0024] In one embodiment, such as Figure 2 As shown, it also includes a backwash inlet pipe 17 and a backwash outlet pipe 18. One end of the backwash inlet pipe 17 is connected to the heat recovery tank 16, and the other end of the backwash inlet pipe 17 is connected to the wort outlet shut-off valve 9 and the wort precooling plate 1 between the wort outlet shut-off valve 9 and the wort precooling plate 1. The backwash inlet pipe 17 is equipped with a backwash pump 19 and a backwash inlet valve 20 in sequence. One end of the backwash outlet pipe 18 is connected to the wort inlet shut-off valve 8 and the wort precooling plate 1 between the wort inlet shut-off valve 8 and the wort precooling plate 1. The backwash outlet pipe 18 is equipped with a backwash outlet valve 21. The controller is electrically connected to the backwash pump 19, the backwash inlet valve 20, and the backwash outlet valve 21.
[0025] When the wort precooling plate 1 is not working, the backwash pump 19, backwash inlet valve 20, and backwash outlet valve 21 can be opened by the controller, and the wort inlet shut-off valve 8 and wort outlet shut-off valve 9 can be closed to flush away the blockage in the wort precooling plate 1.
[0026] Furthermore, the wort precooling plate 1 is equipped with an input pressure sensor 22 at the wort input end and an output pressure sensor 23 at the wort output end. The controller is electrically connected to the input pressure sensor 22 and the output pressure sensor 23. The degree of blockage within the wort precooling plate 1 can be determined by the pressure difference detected by the input pressure sensor 22 and the output pressure sensor 23.
[0027] In one embodiment, a vibrator 24 is provided at the bottom of the wort precooling plate 1. The vibrator 24 is turned on during the operation of the wort precooling plate 1, so that the coagulated matter in the wort is less likely to settle on the wort precooling plate 1, thereby reducing the risk of blockage.
[0028] In one embodiment, a buffer tank 25 is provided on the purified water input pipe 12 between the purified water variable frequency pump 14 and the wort precooling plate 1, which can absorb and reduce the pressure pulsation and flow oscillation of the purified water in the pipe, thereby ensuring the smooth operation and cooling accuracy of the cooling.
[0029] In one embodiment, the wort inlet pipe 2 is equipped with a turbidimeter 26. The amount of coagulated matter in the wort can be determined by the turbidimeter 26, thereby determining whether the upstream filter is malfunctioning.
[0030] Specifically, the controller is a PLC module, a microcontroller, or an industrial computer. The detection signal output by the wort temperature sensor 10 is an analog signal. The detection signals output by the input pressure sensor 22 and the output pressure sensor 23 are also analog signals. The detection signal output by the turbidimeter 26 is an analog signal. That is, the detection signals output by the wort temperature sensor 10, the input pressure sensor 22, the output pressure sensor 23, and the turbidimeter 26 are (4-20mA) analog signals.
[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
