Description

Technical Field

[0001] The invention relates to the technical field of beer brewing, in particular to a beer brewing raw material boiling reaction kettle. Background Art

[0002] In the traditional and complex process of beer brewing, malt fermentation is the key link that determines the quality and taste of beer. With the continuous expansion of beer production scale and the increasing requirements for quality, improving fermentation efficiency has become the focus of the industry.

[0003] Usually, in order to improve the fermentation effect of malt, a stirring mechanism is usually set inside the tank body to mix the malt with the liquid through stirring. Since the liquid will have vortexes during the stirring process, the liquid near the inner wall of the tank body will be higher than the liquid in the center of the tank body, that is, the height of the liquid gradually increases from the inside to the outside. Due to the density and buoyancy characteristics of malt, the floating malt is easy to adhere to the inner wall of the tank body after the stirring stops. These attached malts cannot fully participate in the fermentation reaction, resulting in uneven local fermentation. This not only affects the overall fermentation efficiency, but may also lead to unstable quality and inconsistent taste of beer.

[0004] In view of this, we propose a beer brewing raw material cooking reactor to improve the deficiencies in the prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a beer brewing raw material cooking reactor to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a beer brewing raw material boiling reactor, comprising a boiling tank,

[0007] A stirring assembly is provided at the center of the cooking tank, and the stirring assembly is used to stir the brewing raw materials added into the cooking tank. The stirring assembly comprises at least a plurality of limiting arms, and the side walls of the plurality of limiting arms are slidably connected with a flow guide assembly, and an adjusting assembly is fixedly connected to the upper side of one side of the flow guide assembly;

[0008] When the stirring component stirs the water and malt added into the cooking tank, the guide component is driven to tilt up by the rotating water flow, and the guide component is used to guide the water flow to flush the malt attached to the inner wall of the cooking tank. The adjusting component can drive the guide component to float on the water surface in the cooking tank to adapt to different liquid level heights in the cooking tank. The adjusting component can also reduce the peak height of the vortex generated by the stirring component when the water in the cooking tank is stirred.

[0009] As a further improvement of the technical solution, the stirring assembly also includes a motor, a main rod is provided at the bottom of the motor, the main rod is rotatably connected to the output shaft of the motor, and a plurality of impellers are coaxially connected to the bottom of the main rod.

[0010] As a further improvement of the technical solution, a fixing frame is sleeved on the main rod, the fixing frame is rotatably connected to the main rod, a plurality of the limit arms are fixedly connected to the bottom of the fixing frame, and the fixing frame is fixedly connected to the inner wall of the cooking pot.

[0011] As a further improvement of the present technical solution, the guide assembly includes a limiting groove opened on the limiting arm, a positioning shaft is slidably connected in the limiting groove, and the positioning shaft is rotatably connected to a guide plate in a direction close to the center of the cooking tank.

[0012] As a further improvement of the technical solution, a fixing groove is provided on one side of the guide plate, the positioning shaft is coaxially connected with a torsion spring on one side of the guide plate, the inner ring of the torsion spring is fixedly connected to the periphery of the positioning shaft, and the outer ring of the torsion spring is fixedly connected to the inner ring of the fixing groove.

[0013] As a further improvement of the present technical solution, the adjustment component includes a guide rod arranged in a limiting groove, the positioning shaft is slidably connected to the guide rod, and the adjustment component also includes a cantilever frame fixedly connected to the positioning shaft, and the cantilever frame is provided with a float on the side facing the center of the cooking tank.

[0014] As a further improvement of the technical solution, a cavity is opened inside the float, and the material of the float is aluminum alloy.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the beer brewing raw material cooking reactor, when the water and malt added to the cooking tank are stirred by the stirring component, the guide component is driven to tilt up by the rotating water flow, and the guide component is used to guide the water flow to wash the malt attached to the inner wall of the cooking tank. The multiple impellers arranged at the bottom of the main rod stir and mix the malt, water and other raw materials added to the cooking tank evenly, and the stirred water passes through the upper and lower sides of the guide plate. Since the lower surface of the guide plate is set as a convex arc surface and the upper surface is set as a plane, the flow rate of the water flow passing through the upper and lower surfaces of the guide plate is different, and the guide plate will tilt upward due to the pressure difference between the upper and lower surfaces. The upwardly tilted guide plate guides the rotating water flow upward, and then washes the malt attached to the inner wall of the cooking tank.

[0017] 2. In the beer brewing raw material cooking reactor, the adjustment component is arranged to drive the guide component to float on the water surface in the cooking tank to adapt to different liquid level heights in the cooking tank. The adjustment component can also reduce the peak height of the vortex generated by the stirring component when the water in the cooking tank is stirred. When the amount of brewing raw materials added to the cooking tank is different, the guide plate can always remain below the liquid surface driven by the buoyancy of the float, so that the guide plate can guide the rotating liquid. In addition, the float arranged on the top of the liquid surface can also suppress the peak height of the vortex generated when the liquid rotates, thereby reducing the amount of malt attached to the inner wall of the cooking tank following the rotation of the vortex peak, so that the raw materials for brewing beer can be fermented more thoroughly.

[0033] Example

[0034] See also Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide a beer brewing raw material boiling reactor, including a boiling tank 11,

[0035] A stirring assembly 20 is provided in the center of the cooking tank 11. The stirring assembly 20 is used to stir the brewing raw materials added into the cooking tank 11. The stirring assembly 20 includes at least a plurality of limiting arms 24. The side walls of the plurality of limiting arms 24 are all slidably connected with a flow guide assembly 30. An adjusting assembly 40 is fixedly connected to the upper side of one side of the flow guide assembly 30.

[0036] When the stirring component 20 stirs the water and malt added into the cooking tank 11, the guide component 30 is driven to tilt up by the rotating water flow. The guide component 30 is used to guide the water flow to flush the malt attached to the inner wall of the cooking tank 11. The adjustment component 40 can drive the guide component 30 to float on the water surface in the cooking tank 11 to adapt to different liquid level heights in the cooking tank 11. The adjustment component 40 can also reduce the peak height of the vortex generated by the stirring component 20 when the water in the cooking tank 11 is stirred.

[0037] Working principle: First, water, malt, yeast and other raw materials for brewing beer are added into the cooking tank 11, and then the power of the stirring component 20 is turned on to stir the brewing materials in the cooking tank 11 to accelerate the efficiency of cooking and fermentation. Under the stirring of the stirring component 20, the rotating water flow passes through the upper and lower surfaces of the guide component 30. Under the action of the pressure difference, the movable end of the guide component 30 tilts upward, and the tilted guide component 30 guides the rotating water flow upward to a high place, and then washes the malt attached to the inner wall of the cooking tank 11. In addition, the regulating component 40 arranged at the top of the liquid surface can also suppress the peak height of the vortex generated when the liquid rotates, thereby reducing the amount of malt attached to the inner wall of the cooking tank 11 following the rotation of the vortex peak.

[0038] like Figure 5-Figure 7 As shown, firstly, the specific structure of the guide assembly 30 is disclosed. The guide assembly 30 includes a limiting groove 31 provided on the limiting arm 24, a positioning shaft 35 is slidably connected in the limiting groove 31, and the positioning shaft 35 is rotatably connected to the guide plate 32 in the direction close to the center of the cooking tank 11;

[0039] Furthermore, the multiple impellers 25 arranged at the bottom of the main rod 22 stir and mix the malt, water and other raw materials added to the cooking tank 11 evenly, and the stirred water passes through the upper and lower sides of the guide plate 32. Since the lower surface of the guide plate 32 is set as a convex arc surface and the upper surface is set as a plane, the flow velocities of the water passing through the upper and lower surfaces of the guide plate 32 are different. According to Bernoulli's principle, when the fluid passes through the two sides of the guide plate 32, the pressure on the two sides of the guide plate 32 is negatively correlated with the flow rate of the fluid. Since the path of the water flow from the lower surface of the guide plate 32 is greater than the path of the upper surface, the pressure of the water flow on the lower surface of the guide plate 32 from below is greater than the pressure generated on the upper surface. The guide plate 32 will be tilted upward due to the pressure difference between the upper and lower surfaces. The upward tilted guide plate 32 guides the rotating water flow upward, and then rinses the malt attached to the inner wall of the cooking tank 11.

[0040] Figure 5 and Figure 7 The working state of the adjustment assembly 40 is shown. The specific structure of the adjustment assembly 40 is disclosed below. The adjustment assembly 40 includes a guide rod 41 arranged in the limit groove 31, and the positioning shaft 35 is slidably connected to the guide rod 41. The adjustment assembly 40 also includes a raised frame 42 fixedly connected to the positioning shaft 35. The raised frame 42 is provided with a float 43 on one side facing the center of the cooking tank 11.

[0041] Furthermore, when the amount of brewing raw materials added to the cooking tank 11 is different, the guide plate 32 can always be kept below the liquid surface under the buoyancy of the float 43, so that the guide plate 32 can guide the rotating liquid. In addition, the float 43 disposed on the top of the liquid surface can also suppress the peak height of the vortex generated when the liquid rotates, thereby reducing the amount of malt attached to the inner wall of the cooking tank 11 following the rotation of the vortex peak, so that the raw materials for brewing beer can be fermented more thoroughly.

[0042] To ensure that the malt, water, hops, yeast and other raw materials are fully mixed and the components are evenly distributed, which is conducive to the subsequent reaction and fermentation process to proceed evenly. At the same time, the yeast is more fully exposed to nutrients, which speeds up the reproduction and metabolism of the yeast, thereby improving the speed and efficiency of fermentation;

[0043] like Figure 4 As shown, the stirring assembly 20 also includes a motor 21 , a main rod 22 is provided at the bottom of the motor 21 , the main rod 22 is rotatably connected to the output shaft of the motor 21 , and a plurality of impellers 25 are coaxially connected to the bottom of the main rod 22 .

[0044] The improvements are as follows: a fixing frame 23 is sleeved on the main rod 22, the fixing frame 23 is rotatably connected to the main rod 22, a plurality of limit arms 24 are fixedly connected to the bottom of the fixing frame 23, and the fixing frame 23 is fixedly connected to the inner wall of the cooking tank 11; after the power is turned on, the motor 21 drives the main rod 22 coaxially connected to its own output shaft to rotate, and the main rod 22 drives a plurality of impellers 25 at its bottom to rotate, so as to stir the brewing raw materials in the cooking tank 11, and the multiple impellers 25 can work simultaneously to produce a more complex and powerful flow field, so as to make the mixing of the raw materials more sufficient and uniform.

[0045] In order to enable the guide plate 32 to automatically reset after the stirring step is completed;

[0046] like Figure 5-Figure 7 As shown, a fixing groove 33 is provided on one side of the guide plate 32, and a positioning shaft 35 is coaxially connected with a torsion spring 34 on one side of the guide plate 32, the inner ring of the torsion spring 34 is fixedly connected to the periphery of the positioning shaft 35, and the outer ring of the torsion spring 34 is fixedly connected to the inner ring of the fixing groove 33.

[0047] The improvement lies in that after the lower surface of the guide plate 32 is driven by the rotating water flow, the movable end of the guide plate 32 is tilted upward. At this time, the torsion spring 34 is stretched. After the stirring step of beer brewing is completed, the rotating water flow gradually tends to be still, and the guide plate 32 loses the driving force of the rotating water flow. The guide plate 32, which originally had one end tilted up, rotates and resets under the action of the restoring force of the torsion spring 34.

[0048] In order to ensure that the guide plate 32 is always below the liquid surface, so that the guide plate 32 can always guide the rotating water flow;

[0049] Figure 7 The internal structure of the float 43 is shown. A cavity is provided inside the float 43, and the float 43 is made of aluminum alloy.

[0050] The improvement lies in that the aluminum alloy material itself has high strength, can withstand certain external forces and pressures, is not easily deformed or damaged during the stirring process, and ensures stability during use. In addition, the hollow structure design inside the float 43 allows the float 43 to generate greater buoyancy, so that when the amount of raw materials added to the cooking tank 11 is different, the guide plate 32 can be located below the liquid surface.

[0051] In summary, the working principle of this scheme is as follows: first, raw materials for brewing beer, such as water, malt and yeast, are added into the cooking tank 11, and then the power supply of the motor 21 is turned on to stir the brewing raw materials in the cooking tank 11 to accelerate the efficiency of the cooking and fermentation. Under the stirring of the impeller 25, the rotating water flow passes through the upper and lower surfaces of the guide plate 32. Since the lower surface of the guide plate 32 is set as a convex arc surface and the upper surface is set as a plane, the flow velocities of the water flow passing through the upper and lower surfaces of the guide plate 32 are different. According to Bernoulli's principle, when the fluid passes through both sides of the guide plate 32, the pressure on both sides of the guide plate 32 is negatively correlated with the flow rate of the fluid. Since the path of the water flow passing through the lower surface of the guide plate 32 is greater than the path passed through the upper surface, the pressure of the water flow on the lower surface of the guide plate 32 from below is greater than the pressure generated on the upper surface. The guide plate 32 will be tilted upward due to the pressure difference between the upper and lower surfaces. The tilted guide plate 32 guides the rotating water flow upward, and then rinses the malt attached to the inner wall of the cooking tank 11. In addition, when the amount of brewing raw materials added to the cooking tank 11 is different, the guide plate 32 can always be kept below the liquid surface under the buoyancy of the float 43, so that the guide plate 32 can guide the rotating liquid. In addition, the float 43 arranged on the top of the liquid surface can also suppress the peak height of the vortex generated when the liquid rotates, thereby reducing the amount of malt attached to the inner wall of the cooking tank 11 following the rotation of the vortex peak, so that the raw materials for brewing beer can be fermented more thoroughly.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
