Description

Technical Field

[0001] The utility model belongs to the field of beer production, and in particular relates to a boiling pot for beer production. Background Art

[0002] The boiler is an essential piece of equipment in the beer production process, used to heat the wort to a boil for key steps like protein coagulation, enzyme inactivation, and the development of color and flavor. However, traditional boilers waste significant energy during the heating process.

[0003] Specifically, wort is usually at a relatively low temperature before entering the boiling pot. Directly heating it to a boiling state consumes a lot of energy, and the temperature gradient of the wort during the heating process is large, which can easily lead to local overheating, affecting the taste and quality of the beer. Furthermore, the wort needs to be cooled after boiling, and a large amount of heat it carries is wasted, and additional energy is required for cooling. At the same time, a large amount of high-temperature steam generated during the boiling process is often directly discharged into the environment, resulting in a large amount of heat energy loss, increasing production costs, and also causing thermal pollution to the environment.

[0004] In addition, in order to improve these problems, there is an urgent need on the market for a boiling kettle for beer production that can efficiently utilize thermal energy, reduce energy consumption and improve production efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a boiling pot for beer production.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A boiling pot for beer production comprises a pot body for containing wort and heating and boiling the wort, and also comprises a heat exchanger. Before the low-temperature wort enters the pot body, it exchanges heat with the high-temperature wort flowing out of the pot body in the heat exchanger.

[0008] Furthermore, the liquid inlet and the liquid outlet of the pot body are respectively connected to the cold end outlet and the hot end inlet of the heat exchanger.

[0009] Furthermore, it also includes a liquid reservoir, which is arranged between the cold end outlet of the heat exchanger and the liquid inlet of the pot body.

[0010] Furthermore, the volume of the liquid reservoir is greater than or equal to the volume of the pot body.

[0011] Furthermore, the pot body is heated by steam, and the used steam is connected to the heat exchanger through a secondary steam pipe to exchange heat with the low-temperature wort.

[0012] Furthermore, it also includes a condensed water collection box for collecting condensed water formed after steam heat exchange.

[0013] Furthermore, the condensed water collection tank is also used to collect condensed water condensed on the outer wall of the heat exchanger pipeline.

[0014] After adopting the above technical solution, the beer production boiling pot provided by the utility model has the following beneficial effects compared with the prior art:

[0015] 1. This utility model incorporates a heat exchanger into the boiler system, allowing the low-temperature wort to exchange heat with the hot wort flowing out of the boiler before entering the boiler, thereby pre-raising the temperature of the low-temperature wort while simultaneously cooling the hot wort. This design not only reduces the energy required to directly heat the low-temperature wort, but also makes the entire heating process more uniform, avoiding local overheating and improving beer quality. It also fully recycles heat, saving energy and reducing the additional energy required to cool the hot wort.

[0016] 2. The utility model provides a liquid reservoir and ensures that its volume is greater than or equal to the volume of the pot body, thereby ensuring that a stable buffer area is formed between the heat exchanger and the pot body, making the wort heating process more stable and controllable. This design further improves the stability and production efficiency of the system.

[0017] 3. The utility model also utilizes the used steam to enter the heat exchanger through the secondary steam pipe to exchange heat with the low-temperature wort, thereby realizing efficient recovery of steam heat energy.

[0018] 4. The condensed water collection box added in the present invention is not only used to collect the condensed water formed after steam heat exchange, but also used to collect the condensed water condensed on the outer wall of the heat exchanger pipe, thereby avoiding the waste of water resources and achieving further protection of the production environment.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0033] In the beer production process, wort boiling is a crucial step, which is directly related to the final quality of beer. Its main purpose is to:

[0034] 1. Evaporation of excess water

[0035] By boiling, excess water in the wort is quickly evaporated to make the wort concentration meet the brewing requirements;

[0036] 2. Protein coagulation and precipitation

[0037] During the boiling process, the protein in the wort will coagulate to form a heat coagulum, which will help with subsequent separation and clarification;

[0038] 3. Hop component dissolution

[0039] Hops are added during the boiling process to isomerize the bitter substances in the hops (such as α-acids) into iso-α-acids, which give the beer its unique bitterness and aroma;

[0040] 4. Disinfection and sterilization

[0041] High-temperature boiling can effectively kill microorganisms in the wort and ensure the hygienic quality of beer.

[0042] [Example 1]

[0043] like Figure 1 As shown, this embodiment provides a boiling pot for beer production, which mainly includes a pot body 1 for containing wort and heating and boiling the wort. The wort therein is heated and boiled by heating the pot body 1.

[0044] Wort is usually at a relatively low temperature before entering the boiling pot. Directly heating it to a boiling state consumes a large amount of energy. In addition, the temperature gradient of the wort during the heating process is large, which can easily lead to local overheating, affecting the taste and quality of the beer. In order to solve the above problems, the boiling pot for beer production provided in this embodiment also includes a heat exchanger 2. The liquid inlet and liquid outlet of the pot body 1 are respectively connected to the cold end outlet and hot end inlet of the heat exchanger 2. Before the low-temperature wort enters the pot body 1, it exchanges heat with the high-temperature wort flowing out of the pot body 1 in the heat exchanger 2, thereby pre-raising the temperature of the low-temperature wort. In this way, not only is the energy required for directly heating the low-temperature wort reduced, but the entire heating process is also made more uniform, avoiding the occurrence of local overheating, improving the quality of the beer, and at the same time fully recycling the heat to save energy.

[0045] At the same time, the wort needs to be cooled after boiling, and a large amount of heat it carries is wasted, and additional energy is required for cooling. The utility model uses low-temperature wort to absorb the heat carried by high-temperature wort and cools the high-temperature wort, thereby reducing the additional energy required for cooling the high-temperature wort and shortening the time spent on cooling.

[0046] In a preferred embodiment, the boiling pot for beer production also includes a liquid reservoir 3, which is arranged between the cold end outlet of the heat exchanger 2 and the liquid inlet of the pot body 1. The liquid reservoir 3 is used to accommodate the low-temperature wort that is preheated after heat exchange with the high-temperature wort. After the high-temperature wort in the pot body 1 is completely emptied, the preheated low-temperature wort in the liquid reservoir 3 is released into the pot body 1 to be further heated and boiled. This can prevent the wort that has been boiled from mixing with the wort that has not yet been boiled, thereby reducing its quality. Furthermore, the volume of the liquid reservoir 3 is greater than or equal to the volume of the pot body 1, ensuring that the amount of wort released into the pot body 1 is sufficient, and at the same time ensuring that a stable buffer area is formed between the heat exchanger 2 and the pot body 1, so that the heating process of the wort is more stable and controllable.

[0047] It should be noted that the opening and closing of each pipeline and the power delivery can be controlled by the control valve 5 and the water pump. Those skilled in the art can make settings according to actual conditions. This is not the focus of protection of the present invention and will not be elaborated here.

[0048] [Example 2]

[0049] The difference from the above embodiment is that, Figure 1 The boiling pot for beer production provided in this embodiment has a pot body 1 heated by steam, and the used steam is connected to the heat exchanger 2 through a secondary steam pipe to exchange heat with the low-temperature wort, thereby realizing efficient recovery of steam heat energy.

[0050] Since the temperature of used steam may form condensed water after further reduction, in a preferred embodiment, the beer production boiling pot also includes a condensed water collection box 4, the inlet of which is connected to a lower position of the steam pipeline, for collecting condensed water formed after the steam heat exchange. When a certain amount of water is collected in the condensed water collection box 4, it can be removed by the staff, and the water therein can be recycled. In a preferred embodiment, the condensed water collection box 4 is also used to collect condensed water condensed on the outer wall of the heat exchanger 2 pipeline. The temperature and humidity in the workshop are relatively high. The alternating hot and cold inside the heat exchanger 2 easily form condensed water on the outer wall of the pipeline. If it drips onto the ground, it will cause slippery conditions and easily cause workers to fall and get injured. Therefore, this part of condensed water is collected by the condensed water collection box 4, preventing the ground from getting slippery while achieving water conservation and environmental protection, killing two birds with one stone.

[0051] After adopting the above technical solution, the beer production boiling pot provided by the utility model has the following beneficial effects compared with the prior art:

[0052] 1. This utility model incorporates a heat exchanger into the boiler system, allowing the low-temperature wort to exchange heat with the hot wort flowing out of the boiler before entering the boiler, thereby pre-raising the temperature of the low-temperature wort while simultaneously cooling the hot wort. This design not only reduces the energy required to directly heat the low-temperature wort, but also makes the entire heating process more uniform, avoiding local overheating and improving beer quality. It also fully recycles heat, saving energy and reducing the additional energy required to cool the hot wort.

[0053] 2. The utility model provides a liquid reservoir and ensures that its volume is greater than or equal to the volume of the pot body, thereby ensuring that a stable buffer area is formed between the heat exchanger and the pot body, making the wort heating process more stable and controllable. This design further improves the stability and production efficiency of the system.

[0054] 3. The utility model also utilizes the used steam to enter the heat exchanger through the secondary steam pipe to exchange heat with the low-temperature wort, thereby realizing efficient recovery of steam heat energy.

[0055] 4. The condensed water collection box added in the present invention is not only used to collect the condensed water formed after steam heat exchange, but also used to collect the condensed water condensed on the outer wall of the heat exchanger pipe, thereby avoiding the waste of water resources and achieving further protection of the production environment.
