Description

Technical Field

[0001] This invention belongs to the field of beer production technology, and in particular relates to a beer production process and its production equipment. Background Technology

[0002] Beer fermentation is a crucial step in the brewing process, mainly involving the conversion of sugar into alcohol and carbon dioxide. It also helps to remove some off-flavors that may be present in the raw materials, making the beer purer. The quality of fermentation directly affects the quality and flavor of the final product.

[0003] In current beer fermentation processes, temperature, pressure, and sugar concentration are typically monitored manually by technicians based on experience. This method of adjustment is not timely enough. If the temperature, pressure, and sugar concentration fluctuate too much, it will directly affect the quality of beer fermentation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a beer production process and its equipment, thus solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a beer production device, comprising a tank body, wherein the tank body is provided with an injection port for liquid introduction, and further comprising:

[0006] A liquid injection mechanism, installed on the tank, is used to introduce sugar solution, clarifying agent, or water into the tank.

[0007] A filter funnel, installed on the tank, is used to filter fermented beer lees. The filter funnel is slidably engaged with a limiting groove (not shown in the figure) opened on the tank. The bottom and end of the filter funnel are fixedly connected to the other end of an elastic member fixedly connected to the tank.

[0008] The main shaft is limited and slidably positioned with a ratchet embedded in the tank body and is rotatably connected to the filter funnel.

[0009] Agitator B is sleeved and installed on the main shaft and is used to agitate the materials located inside the tank.

[0010] The drive assembly, mounted on the tank, is used to drive the main shaft to perform linear motion or rotation in the vertical direction.

[0011] The liquid injection mechanism includes three sets of components for injecting sugar solution, clarifying agent, and water into the tank respectively. Each component comprises a cylinder, a cavity, an injection pipe, a piston plate, and a linear motion component. The cylinder is mounted on the tank, the cavity communicates with the tank via the injection pipe, the piston plate slides within the cavity, and the piston plate is fixedly connected to the output shaft of the linear motion component fixedly connected to the cylinder. The mechanism also includes:

[0012] The stirring assembly, mounted on the piston plate, is used to stir and mix the liquid located in the cavity.

[0013] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0014] Further technical solution: The stirring assembly includes a guide rod, a rotating cylinder and a stirring component A. The guide rod is fixedly connected to the cylinder body, the rotating cylinder is rotatably connected to the piston plate, and the lower end of the guide rod is fixedly connected to a push column that slides in cooperation with a spiral groove opened in the rotating cylinder.

[0015] Further technical solution: The drive assembly includes a motor, crown gear A and crown gear B. The motor is detachably mounted on the tank body. The output shaft of the motor is fixedly connected to crown gear A. Crown gear B is fixedly connected to the upper end of the main shaft and meshes with crown gear A.

[0016] Further technical solutions include an information acquisition module for obtaining information on liquid temperature, gas pressure, sugar concentration, alcohol concentration, and clarity within the tank.

[0017] Further technical solution: The information acquisition module includes:

[0018] A temperature sensor, installed inside the tank, is used to collect information about the temperature of the liquid inside the tank.

[0019] A pressure sensor is installed inside the tank to collect pressure information inside the tank.

[0020] A saccharimeter is used to collect information on the sugar concentration of liquids inside a tank.

[0021] An infrared spectral sensor is used to collect information on the alcohol concentration of the liquid inside the container;

[0022] A turbidimeter is used to collect information on the clarity of liquids inside a tank.

[0023] A beer production process, using the aforementioned beer production equipment, includes the following steps:

[0024] S1. Technicians introduce the beer raw materials into the tank through the injection port and then seal the tank.

[0025] S2. The information acquisition module collects liquid temperature, air pressure, and sugar concentration information within the tank. This information is compared to preset temperature, air pressure, and sugar concentration thresholds. If the temperature is outside the threshold, the temperature control pipeline is activated to control the liquid temperature. Simultaneously, the drive assembly is activated to rotate the agitator B, stirring the liquid and uniformly heating or cooling it until the temperature falls within the threshold. If the air pressure is outside the threshold, the discharge valve is activated. The valves inside the vent release or pressurize the tank. Simultaneously, the drive assembly is activated, driving the main shaft to rotate the agitator B and stir the liquid inside the tank to prevent air bubbles from forming inside the liquid, until the air pressure information inside the tank is within the air pressure threshold. If the sugar concentration information is not within the sugar concentration threshold, the liquid injection mechanism is activated to inject sugar solution or water into the tank. At the same time, the drive assembly is activated, driving the main shaft to rotate the agitator B and stir the liquid inside the tank to make the sugar concentration in the liquid inside the tank uniform, until the sugar concentration information in the liquid inside the tank is within the sugar concentration threshold.

[0026] S3. Under the condition that the temperature information, air pressure information and sugar concentration information are all within the corresponding threshold, the dimensionless processing is performed and then imported into the fermentation control model, and then the fermentation control coefficient is output. The obtained fermentation control coefficient is compared with the fermentation control coefficient threshold. If the fermentation control coefficient is not within the fermentation coefficient threshold, the temperature information, air pressure information and sugar concentration information are adjusted until the fermentation control coefficient is within the fermentation control coefficient threshold.

[0027] S4. After fermentation is complete, the information acquisition module obtains the alcohol concentration and clarity information of the liquid in the tank. The alcohol concentration and clarity information are compared with the alcohol concentration threshold and clarity threshold, respectively. If the alcohol concentration information is not within the alcohol concentration threshold, the yeast type is changed in the next fermentation. If the clarity information is not within the clarity threshold, the amount of clarifying agent injected is adjusted until the clarity information is within the clarity threshold. The obtained clarity and alcohol information are dimensionless and then imported into the fermentation evaluation model to output the fermentation evaluation coefficient. The obtained fermentation evaluation coefficient is compared with the fermentation evaluation coefficient threshold. If the fermentation evaluation coefficient is not within the fermentation evaluation coefficient threshold, the fermentation control coefficient is adjusted, the yeast type is changed, or the amount of clarifying agent injected is adjusted in the next fermentation until the fermentation evaluation coefficient is within the fermentation evaluation coefficient threshold in the next fermentation.

[0028] A further technical solution: The fermentation control model is represented as follows:

[0029]

[0030] in, This is the fermentation control coefficient. For temperature information, For sugar concentration information, This is air pressure information. Temperature information is an influencing factor. Factors affecting sugar concentration information It is a common influencing factor for both temperature and sugar concentration information. , , .

[0031] Further technical solution: The fermentation evaluation model is expressed as follows:

[0032]

[0033] in, Indicates the fermentation evaluation coefficient. Indicates alcohol concentration information. Indicates clarification information. Indicates the fermentation control coefficient. Factors influencing alcohol concentration information This indicates the impact factor of clarification information. , .

[0034] This invention provides a beer production process and equipment, which has the following advantages compared with the prior art:

[0035] 1. Technicians introduce the beer raw materials into the tank through the injection port. At this time, a temperature control pipe, along with a temperature sensor installed inside the tank, controls the temperature. Simultaneously, a pressure sensor installed inside the tank, along with a vent hole with a valve, controls the pressure within the tank. During temperature control, pressure control, or liquid injection, the motor drives crown gear A to rotate forward. The right-angled edges of the teeth of crown gear A engage with the right-angled edges of the teeth of crown gear B. Crown gear A then drives crown gear B, causing the main shaft to rotate vertically. This, in turn, drives the agitator B to vertically agitate the liquid within the tank, thus promoting the flow of the liquid. There is no temperature difference during temperature control; air bubbles in the liquid can be expelled during gas pressure control; and sugar solution or clarifying agent can be mixed evenly during injection. After fermentation is complete, the gate valve located at the bottom of the tank is opened to allow the fermented beer to be filtered through the filter funnel and discharged from the tank. At this time, when the motor drives the crown gear A to reverse, the inclined edge of the teeth of crown gear A and crown gear B are subjected to force. At the same time, under the limit of the ratchet, the main shaft and crown gear B cannot rotate. Meanwhile, the elastic element can provide elastic support for the filter funnel and the main shaft. At this time, crown gear A is misaligned relative to crown gear B, which causes crown gear B to drive the main shaft to drive the filter funnel to vibrate, thereby vibrating and discharging the filter residue on the filter funnel.

[0036] 2. This invention can evaluate and adjust the quality of beer fermentation based on information such as temperature, air pressure, sugar concentration, alcohol concentration, and clarity, thereby improving the efficiency and quality of beer fermentation. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0045] Please see Figures 1 to 5 According to one embodiment of the present invention, a beer production device includes a tank 1, wherein the tank 1 has an injection port (not shown in the figure) for liquid introduction, and further includes:

[0046] Liquid injection mechanism 3, installed on tank 1, is used to introduce sugar solution, clarifying agent or water into tank 1;

[0047] A filter funnel is installed on the tank body 1 and is used to filter the fermented beer lees. The filter funnel is slidably engaged with the limiting groove (not shown in the figure) opened on the tank body 1. The bottom and end of the filter funnel 4 are fixedly connected to the other end of the elastic member 5 fixedly connected to the tank body 1.

[0048] The main shaft 6 is limited to sliding with the ratchet 10 embedded in the tank 1 and is rotatably connected to the filter funnel 4;

[0049] The agitator B7 is sleeved and installed on the main shaft 6 and is used to agitate the material located in the tank 1.

[0050] Drive assembly 9, mounted on tank 1, is used to drive main shaft 6 to perform linear motion or rotation in the vertical direction;

[0051] The liquid injection mechanism 3 has three sets of components for injecting sugar solution, clarifying agent, and water into the tank 1 respectively. It includes a cylinder 301, a cavity 302, an injection pipe 303, a piston plate 304, and a linear motion component 305. The cylinder 301 is mounted on the tank 1. The cavity 302 communicates with the tank 1 through the injection pipe 303. The piston plate 304 slides within the cavity 302. The piston plate 304 is fixedly connected to the output shaft of the linear motion component 305, which is fixedly connected to the cylinder 301. The mechanism also includes:

[0052] The stirring assembly 306 is mounted on the piston plate 304 and is used to stir and mix the liquid located in the cavity 302;

[0053] The stirring assembly 306 includes a guide rod 3061, a rotating cylinder 3062, and a stirring element A3063. The guide rod 3061 is fixedly connected to the cylinder 301, and the rotating cylinder 3062 is rotatably connected to the piston plate 304. The lower end of the guide rod 3061 is fixedly connected to a push column (not shown in the figure) that slides in cooperation with a spiral groove (not shown in the figure) opened in the rotating cylinder 3062. The linear motion element 305 pushes the piston plate 304 to move linearly in the vertical direction along the cavity 302, introducing the liquid in the cavity 302 into the injection pipe 303 and then into the tank 1. At the same time, the piston plate 304 can push the rotating cylinder 3062 to move linearly in the vertical direction relative to the guide rod 3061. At this time, the push column slides along the spiral groove, thereby pushing the rotating cylinder 3062 to drive the stirring element A3063 to rotate in the vertical direction, thus realizing the mixing and stirring of the liquid in the cavity 302 while introducing it into the tank 1.

[0054] The drive assembly 9 includes a motor 901, a crown gear A902, and a crown gear B903. The motor 901 is detachably mounted on the tank body 1. The output shaft of the motor 901 is fixedly connected to the crown gear A902. The crown gear B903 is fixedly connected to the upper end of the main shaft 6 and meshes with the crown gear A902. When the motor 901 rotates forward, it drives the crown gear A902 to rotate forward as well. At this time, the right-angled edge of the teeth of the crown gear A902 engages with the right-angled edge of the teeth of the crown gear B903, thereby using the crown gear A902 to drive the crown gear B903 to drive the main shaft. 6. When the motor 901 drives the crown gear A902 to rotate in reverse, the inclined sides of the teeth of the crown gear A902 and the inclined sides of the teeth of the crown gear B903 are subjected to force. At the same time, under the limit of the ratchet 10, the main shaft 6 and the crown gear B903 cannot rotate. Meanwhile, the elastic element 5 can provide elastic support for the filter funnel 4 and the main shaft 6. At this time, the crown gear A902 is misaligned relative to the crown gear B903, which causes the crown gear B903 to drive the main shaft 6 to drive the filter funnel 4 to vibrate, thereby vibrating and discharging the filter residue on the filter funnel 4.

[0055] Preferably, it further includes an information acquisition module for acquiring information on liquid temperature, gas pressure, sugar concentration, alcohol concentration, and clarity within the tank 1. The information acquisition module includes:

[0056] A temperature sensor is installed inside tank 1 to collect the temperature information of the liquid inside tank 1.

[0057] A pressure sensor is installed inside tank 1 to collect pressure information inside tank 1.

[0058] A saccharimeter is used to collect information on the sugar concentration of the liquid in tank 1.

[0059] An infrared spectral sensor is used to collect information on the alcohol concentration of the liquid inside tank 1.

[0060] A turbidimeter is used to collect information on the clarity of the liquid inside tank 1.

[0061] In this embodiment of the invention, the technician introduces the beer raw materials into the tank 1 through the injection port. At this time, the temperature inside the tank 1 is controlled by a temperature control pipe 8 in conjunction with a temperature sensor installed inside the tank 1. Simultaneously, the air pressure inside the tank 1 is controlled by a pressure sensor installed inside the tank 1 in conjunction with an exhaust port on the tank 1 equipped with a valve. During temperature control, air pressure control, or liquid injection by the liquid injection mechanism 3, the motor 901 drives the crown gear A902 to rotate forward. At this time, the right-angled edge of the teeth of crown gear A902 engages with the right-angled edge of the teeth of crown gear B903. This allows crown gear A902 to drive crown gear B903, which in turn drives the main shaft 6 to rotate vertically. The main shaft 6 then drives the stirring element B7 to stir vertically within the tank 1, thereby promoting the stirring of the liquid. There is no temperature difference during temperature control; air bubbles in the liquid can be expelled during gas pressure control; and sugar solution or clarifying agent can be mixed evenly during injection. After fermentation is complete, the gate valve located below tank 1 is opened to allow the fermented beer to be filtered through the filter funnel 4 and discharged from tank 1. At this time, when motor 901 drives crown gear A902 to reverse, the inclined edge of the teeth of crown gear A902 and crown gear B903 are subjected to force. At the same time, under the limit of ratchet 10, the main shaft 6 and crown gear B903 cannot rotate. Meanwhile, the elastic element 5 can elastically support the filter funnel 4 and the main shaft 6. At this time, crown gear A902 is misaligned relative to crown gear B903, which causes crown gear B903 to drive the main shaft 6 to drive the filter funnel 4 to vibrate, thereby vibrating and discharging the filter residue on the filter funnel 4.

[0062] Please see Figures 1 to 5 As an embodiment of the present invention, a beer production process using the above-mentioned beer production equipment includes the following steps:

[0063] S1. Technicians introduce the beer raw materials into tank 1 through the injection port and then seal tank 1.

[0064] S2. The information acquisition module collects the liquid temperature, air pressure, and sugar concentration information in tank 1. The collected information is compared with preset temperature, air pressure, and sugar concentration thresholds. If the temperature information is not within the threshold, the temperature control pipe 8 is activated to control the temperature of the liquid in tank 1. Simultaneously, the drive assembly 9 is activated to drive the main shaft 6 to rotate the stirring component B7, stirring the liquid in tank 1 and uniformly heating or cooling it until the temperature information is within the threshold. If the air pressure information is not within the threshold, the vent is opened. The valves depressurize or pressurize the tank 1. At the same time, the drive assembly 9 drives the main shaft 6 to rotate the agitator B7 to stir the liquid in the tank 1, preventing air bubbles from forming inside the liquid, until the air pressure information in the tank 1 is within the air pressure threshold. If the sugar concentration information is not within the sugar concentration threshold, the liquid injection mechanism 3 is activated to inject sugar solution or water into the tank 1. At the same time, the drive assembly 9 drives the main shaft 6 to rotate the agitator B7 to stir the liquid in the tank 1, so as to make the sugar concentration of the liquid in the tank 1 uniform, until the sugar concentration information of the liquid in the tank 1 is within the sugar concentration threshold.

[0065] S3. Under the condition that the temperature, air pressure, and sugar concentration information are all within their respective thresholds, the data are processed to be dimensionless and then imported into the fermentation control model. The fermentation control coefficient is then output, and the obtained fermentation control coefficient is compared with the fermentation control coefficient threshold. If the fermentation control coefficient is not within the threshold, the temperature, air pressure, and sugar concentration information are adjusted until the fermentation control coefficient is within the threshold. The fermentation control model is expressed as follows:

Temperature information is an influencing factor. Factors affecting sugar concentration information It is a common influencing factor for both temperature and sugar concentration information. , , ;

[0068] S4. After fermentation is complete, the alcohol concentration and clarity information of the liquid in tank 1 are acquired through the information acquisition module. The alcohol concentration and clarity information are compared with alcohol concentration thresholds and clarity thresholds. If the alcohol concentration is not within the alcohol concentration threshold, the yeast species is changed during the next fermentation. If the clarity is not within the clarity threshold, the amount of clarifying agent injected is adjusted until the clarity is within the clarity threshold. The acquired clarity and alcohol information are dimensionless and then imported into the fermentation evaluation model to output the fermentation evaluation coefficient. The acquired fermentation evaluation coefficient is compared with the fermentation evaluation coefficient threshold. If the fermentation evaluation coefficient is not within the fermentation evaluation coefficient threshold, the fermentation control system is regulated, the yeast species is changed, or the amount of clarifying agent injected is adjusted during the next fermentation until the fermentation evaluation coefficient is within the fermentation evaluation coefficient threshold during the next fermentation. The fermentation evaluation model is expressed as follows:
