Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of beer brewing, and in particular to a steam recycling device for a wort boiling pot and a beer production equipment. Background Art

[0002] Wort (i.e., malt extract) boiling is an important process in beer production, which is used to evaporate water, concentrate the wort concentration and remove the bad flavors in the wort. In the prior art, a wort boiling pot is mostly used to achieve wort boiling. Specifically, a steam pipeline is provided on the circumferential side wall of the wort boiling pot body. When wort boiling is required, steam is introduced into the steam pipeline, and the steam is used to heat and boil the wort contained in the wort boiling pot. During the wort boiling process, the wort is heated and steam, i.e., secondary steam, will also be generated in the wort boiling pot body.

[0003] The existing methods for recycling secondary steam are, for example: introducing the energy storage water of the energy storage system to exchange heat with the secondary steam to cool the secondary steam, and the energy storage water after heat exchange is put into production for reuse. However, the high-grade steam calorific value is converted into the low-grade energy storage water calorific value, and the recycling rate of secondary steam is low, resulting in serious waste of heat energy.

[0049] In the technical solutions of this disclosure, similar terms such as "connected", "coupled", or "linked" are not limited to physical or mechanical connections, but may include electrical connections.

[0050] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0051] An embodiment of the present invention provides a steam reuse device for a wort boiling pot. Refer to Figure 1 as shown, including:

[0052] Steam compressor 1, the intake port 11 is communicated with the secondary steam discharge port 101 of the wort boiling pot 100;

[0053] The heat exchanger 2, the heat source steam inlet 21 is communicated with the pressurized steam discharge port 12 of the steam compressor 1, and the heat source steam outlet 22 is communicated with the inlet of a condensate tank (not shown in the figure).

[0054] The wort circulation pipeline 3 includes a first pipeline 31 and a second pipeline 32.

[0055] One end of the first pipeline 31 is communicated with the wort outlet 102 at the bottom of the wort boiling pot 100, and the other end is communicated with the heating inlet 23 of the heat exchanger 2.

[0056] One end of the second pipeline 32 is communicated with the heating outlet 24 of the heat exchanger 2, and the other end is communicated with the wort inlet 103 at the top of the wort boiling pot 100.

[0057] It should be noted that the gas pressure of the secondary steam is low, usually only 0.2 bar, and it is difficult to recycle its heat energy. In the embodiment of the present invention, by setting the steam compressor 1 to pressurize the secondary steam, the heat energy utilization rate of the secondary steam can be effectively improved, and energy can be saved.

[0058] In the embodiment of the present invention, setting the wort circulation pipeline 3 increases the heat exchange area of the wort, ensures that the wort fully absorbs the heat from the pressurized steam, and improves the heat energy utilization rate.

[0059] Specifically, in the process of the wort boiling process, the steam compressor 1 pressurizes the secondary steam discharged from the wort boiling pot 100, and discharges the pressurized steam into the heat exchanger 2 through the pressurized steam discharge port 12 and the heat source steam inlet 21. In the heat exchanger 2, the pressurized steam releases heat to heat the wort that enters the heat exchanger 2 through the first pipeline 31 and the heating inlet 23. After that, the wort heated by the heat exchanger 2 further returns to the wort boiling pot 100 through the heating outlet 24, the second pipeline 32 and the wort inlet 103. The embodiment of the present invention can realize the recycling of the secondary steam and can provide heat energy for the wort boiling.

[0060] In an embodiment of the present utility model, the steam recycling device includes: a steam compressor 1, an air inlet 11 communicating with a secondary steam discharge port 101 of a wort boiling pan 100; a heat exchanger 2, a heat source steam inlet 21 communicating with a pressurized steam discharge port 12 of the steam compressor 1, and a heat source steam outlet 22 communicating with an inlet of a condensate tank; a wort circulation pipeline 3, including a first pipeline 31 and a second pipeline 32; one end of the first pipeline 31 communicating with a wort outlet 102 at the bottom of the wort boiling pan 100, and the other end communicating with a heated inlet 23 of the heat exchanger 2; one end of the second pipeline 32 communicating with a heated outlet 24 of the heat exchanger 2, and the other end communicating with a wort inlet 103 at the top of the wort boiling pan 100. The embodiment of the present utility model realizes the efficient recycling and utilization of secondary steam, with a high recycling rate, which can reduce the heat energy loss during the wort boiling process and save resources.

[0061] In some embodiments of the present utility model, optionally, the wort circulation pipeline 3 further includes:

[0062] A pumping device 33, provided on the first pipeline 31, for pumping the wort in the first pipeline 31 into the heated inlet 23.

[0063] In an embodiment of the present utility model, by providing the pumping device 33, it can ensure that the wort flows from the wort outlet 102 at the bottom of the wort boiling pan 100 through the heat exchanger 2 and then returns to the wort inlet 103 at the top of the wort boiling pan 100, ensuring that the wort is smoothly heated. In addition, by providing the pumping device 33, the flow rate of the wort in the first pipeline 31 and the second pipeline 32 is increased, and the heat exchange efficiency is improved.

[0064] In some embodiments of the present utility model, optionally, the steam recycling device further includes: a first pressure transmitter 4, and a controller;

[0065] Through a third pipeline 5, the air inlet 11 communicates with the secondary steam discharge port 101 of the wort boiling pan 100;

[0066] The first pressure transmitter 4 is provided on the third pipeline 5;

[0067] The controller includes:

[0068] A first control interface, for receiving the pressure signal sent by the first pressure transmitter 4 and forwarding the pressure signal to an interaction terminal associated with the user.

[0069] Through the above settings of the embodiment of the present utility model, the user can determine the air pressure value of the secondary steam in the third pipeline 5 through the pressure signal, which is convenient for the user to adjust the operation of the steam recycling device according to the air pressure value of the secondary steam.

[0070] It should be noted that the controller in the embodiments of the present utility model may include a PLC controller, and the controller and the first pressure transmitter 4 may be electrically connected by wired or wireless means.

[0071] In some embodiments of the present utility model, optionally, the steam recycling device further includes: an exhaust pipe 6, and a first valve 7;

[0072] One end of the exhaust pipe 6 is communicated with the third pipe 5;

[0073] The first valve 7 is arranged on the exhaust pipe 6 and is used to control the connection or disconnection between the third pipe 5 and the exhaust pipe 6;

[0074] The first control interface is further used to receive the first valve 7 opening signal or the first valve 7 closing signal sent by the interaction end, and forward the first valve 7 opening signal or the first valve 7 closing signal to the first valve 7.

[0075] In the embodiments of the present utility model, the other end of the exhaust pipe 6 may be directly communicated with the external atmosphere to discharge the secondary steam.

[0076] The following is described in conjunction with specific examples. When the user determines through the pressure signal that the gas pressure value of the secondary steam in the third pipe 5 does not meet the inlet steam pressure threshold range of the steam compressor 1, the user can send the first valve 7 opening signal to the first control interface through the interaction end, and discharge the secondary steam in the third pipe 5 to the external atmosphere through the exhaust pipe 6 to ensure the safe and stable operation of the steam compressor 1. When the user determines through the pressure signal that the gas pressure value of the secondary steam in the third pipe 5 meets the inlet steam pressure threshold range of the steam compressor 1, the user can send the first valve 7 closing signal to the first control interface through the interaction end to realize the recycling of the secondary steam.

[0077] It should be noted that for the inlet steam pressure threshold range of the steam compressor 1, various types of steam compressors 1 are not the same. And this steam pressure threshold range is determined when the steam compressor 1 leaves the factory, and it is impossible to list them all here. The fact that it is impossible to list them all should not be considered unclear.

[0078] In some embodiments of the present utility model, optionally, the steam recycling device further includes: a temperature transmitter 8, and a controller;

[0079] Through the fourth pipe 9, the heat source steam inlet 21 is communicated with the pressurized steam discharge port 12; the temperature transmitter 8 is arranged on the fourth pipe 9;

[0080] The controller includes:

[0081] A second control interface, which is used to receive the temperature signal sent by the temperature transmitter 8 and forward the temperature signal to the interaction end associated with the user.

[0082] In the embodiment of the present utility model, through the setting of the temperature transmitter 8, the measurement of the steam temperature in the fourth pipeline 9 is realized. Further, by forwarding the temperature signal to the interaction end through the second control interface, it is convenient for users to control the operation of the steam reuse device according to the temperature signal.

[0083] In some embodiments of the present utility model, optionally, the steam reuse device further includes:

[0084] A second pressure transmitter 10, which is arranged on the fourth pipeline 9;

[0085] The controller further includes:

[0086] A third control interface, which is used to receive the pressure signal sent by the second pressure transmitter 10 and forward the pressure signal to the interaction end.

Further, by forwarding the pressure signal to the interaction end through the third control interface, it is convenient for users to control the operation of the steam reuse device according to the pressure signal.

[0088] In some embodiments of the present utility model, optionally, the steam reuse device further includes: a flowmeter 14, which is arranged on the fourth pipeline 9. Users can determine the flow rate of the steam in the fourth pipeline 9 according to the reading of the flowmeter 14, which is convenient for users to control the operation of the steam reuse device.

[0089] In some embodiments of the present utility model, optionally, the steam reuse device further includes:

[0090] A check valve 13, which is arranged on the fourth pipeline 9 and is used to limit the steam in the fourth pipeline 9 from flowing back to the supercharged steam discharge port 12. The above setting can avoid the harm caused by steam backflow and ensure the safe and stable operation of the steam reuse device.

[0091] In some embodiments of the present utility model, optionally, the pressure value K of the steam at the supercharged steam discharge port satisfies: 0.08 MPa ≤ K ≤ 0.12 MPa. That is to say, the steam compressor 1 supercharges the secondary steam to within the pressure value range of K. Specifically, it can be realized by directly setting the operating parameters of the steam compressor 1. Actual measurement proves that the above pressure value K is beneficial to improving the thermal energy utilization efficiency of the secondary steam, realizing the efficient heating of the wort, and ensuring the long-term safe and stable operation of the steam reuse device.
