Description

Technical Field

[0001] The invention relates to the technical field of high-viscosity fluids, and in particular to a rotary ultra-high temperature sterilization device. Background Art

[0002] Ultra-high temperature sterilization technology is to heat the fluid or semi-fluid to 135-150℃ within 28s, and then quickly cool it to 30-40℃. In this process, the death rate of microorganisms and bacteria is much faster than the speed at which the food quality deteriorates due to chemical changes caused by heat. Therefore, the instantaneous high temperature can completely kill the bacteria, but it has little effect on the quality of the food, and can almost completely maintain the original color, aroma and taste of the food. This sterilization technology has been widely used in the production process of milk, juice and various beverages, soy milk tea, wine and other products. Commonly used ultra-high temperature sterilization equipment includes tubular heat exchangers, plate heat exchangers and rotary cone heat exchangers.

The high-viscosity fluid has a single flow direction inside, and the fluid movement is in a relatively stable state. Dirt is easily deposited, causing blockage. In addition, the heat transfer coefficient of the fluid in a stable state of movement is reduced, and the heat exchange efficiency is not high, resulting in poor sterilization effect. For example, the channels between the plates of a plate heat exchanger are relatively narrow, and high-viscosity fluids with high viscosity are easy to block the channels between the plates.

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Ultra-high temperature sterilization technology is to heat the fluid or semi-fluid to 135-150℃ within 28s, and then quickly cool it to 30-40℃. In this process, the death rate of microorganisms and bacteria is much faster than the speed at which the food quality deteriorates due to chemical changes caused by heat. Therefore, the instantaneous high temperature can completely kill the bacteria, but it has little effect on the quality of the food, and can almost completely maintain the original color, aroma and taste of the food. This sterilization technology has been widely used in the production process of milk, juice and various beverages, soy milk tea, wine and other products. Commonly used ultra-high temperature sterilization equipment includes tubular heat exchangers, plate heat exchangers and rotary cone heat exchangers.

[0036] However, when processing high-viscosity fluids, existing equipment is affected by the slow flow speed and high viscosity of high-viscosity fluids. The high-viscosity fluid has a single flow direction inside, and the fluid movement is in a relatively stable state. Dirt is easily deposited, causing blockage. In addition, the heat transfer coefficient of the fluid in a stable state of movement is reduced, and the heat exchange efficiency is not high, resulting in poor sterilization effect. For example, the channels between the plates of a plate heat exchanger are relatively narrow, and high-viscosity fluids with high viscosity are easy to block the channels between the plates.

[0037] In the embodiment of the present invention, a structure in which the second shell is sleeved on the outside of the first shell is adopted, and the two surfaces close to the first shell and the second shell are set as corrugated structures, so that a corrugated channel is formed between the first shell and the second shell, and a first flow guide structure is set on the outer surface of the first shell, and the first flow guide structure rotates with the first shell. On the one hand, the corrugated channel can increase the contact area of ​​the material heat exchange, and the two heat flow domains formed in the first shell and the second shell exchange heat at the same time, thereby improving the heat exchange efficiency. On the other hand, the corrugated shape can play a role of flow disturbance, and the corrugated structure is used to disturb the flow direction of the material. At the same time, under the rotation of the first shell and the first flow guide structure, the flow state of the material is constantly disturbed to form turbulence, which increases the flow speed and heat convection heat transfer coefficient of the material. The turbulence of the fluid can break the thermal boundary layer in the fluid, making it easier to transfer heat to the fluid on the other side, thereby realizing heat transfer, reducing the phenomenon that high-viscosity fluid materials are easy to block and scale, and the heat exchange efficiency is thus improved. Thereby further improving the sterilization effect of high-viscosity fluid materials.

[0038] Combine the following Figures 1 to 6 The present invention provides a rotary ultra-high temperature sterilization device, which includes a first shell 1, a second shell 2 and a first flow guide structure 4. The first shell 1 has a central axis and is suitable for being rotated along the central axis. The outer surface of the first shell 1 is a corrugated structure with ridges and grooves. Preferably, the outer surface of the first shell 1 is a sinusoidal function corrugated structure. The first shell 1 is suitable for passing a first fluid.

[0039] The second shell 2 is sleeved on the outside of the first shell 1 and is coaxially arranged with the first shell 1. The surface of the second shell 2 close to the first shell 1 is a corrugated structure that is the same as the outer surface of the first shell 1, so that a corrugated channel 3 is formed between the outer surface of the first shell 1 and the surface of the second shell 2. The top of the corrugated channel 3 is a feed port 31, and the bottom is a discharge port 32. The second shell 2 is suitable for passing the second fluid, and the corrugated channel 3 is suitable for passing the material to be processed.

[0040] The first guide structure 4 is arranged on the outer surface of the first shell 1. The first guide structure 4 can be specifically set as a plurality of guide plates or guide groove structures. Each guide plate or guide groove is arranged along the central axis direction of the first shell 1, and the plurality of guide plates or guide grooves are evenly distributed along the circumference of the outer surface of the first shell 1.

[0041] During operation, a high-temperature first fluid and a high-temperature second fluid are introduced into the first shell 1 and the second shell 2 respectively. The first fluid and the second fluid can be water or other medium with good thermal conductivity, so that a high-temperature first heat flow region 14 is formed in the first shell 1 and a high-temperature second heat flow region 23 is formed in the second shell 2. The high-viscosity fluid material to be processed is introduced into the corrugated channel 3 between the first shell 1 and the second shell 2 through the feed port 31. As the first shell 1 rotates, the first flow guide structure 4 on the first shell 1 rotates with the first shell 1, fully stirring the material in the corrugated channel 3 while guiding it. The first heat flow region 14 and the second heat flow region 23 simultaneously exchange heat with the material in the corrugated channel 3, achieving a uniform heat exchange effect. Driven by the first flow-guiding structure 4, on the one hand, the material in the corrugated channel 3 is in a turbulent state, which improves the heat exchange efficiency while accelerating the flow rate of the material and reducing the deposition and scaling of high-viscosity fluid materials. On the other hand, the high-viscosity fluid material in the corrugated channel 3 is pushed in a thin film state, and the material film will not be coked under high-speed rotation, which effectively improves the heat transfer efficiency and thus improves the sterilization effect.

[0042] After the sterilization is completed, the material flows out from the discharge port 32 and enters the storage box for cooling, thereby completing the efficient sterilization process.

[0043] In this embodiment, the second shell 2 is sleeved on the outside of the first shell 1, and the two surfaces of the first shell 1 and the second shell 2 close to each other are set as corrugated structures, so that a corrugated channel 3 is formed between the first shell 1 and the second shell 2, and the first flow guide structure 4 is set on the outer surface of the first shell 1, and the first flow guide structure 4 rotates with the first shell 1. On the one hand, the corrugated channel can increase the contact area of ​​the material heat exchange, and the two heat flow domains formed in the first shell 1 and the second shell 2 exchange heat at the same time, thereby improving the heat exchange efficiency. On the other hand, the corrugated shape can play a role of disturbing flow, and the corrugated structure is used to disturb the flow direction of the material. At the same time, under the rotation of the first shell 1 and the first flow guide structure 4, the flow state of the material is constantly disturbed to form turbulence, which increases the flow speed and heat convection heat transfer coefficient of the material. The turbulence of the fluid can break the thermal boundary layer in the fluid, making it easier to transfer heat to the fluid on the other side, thereby realizing heat transfer, reducing the phenomenon that high-viscosity fluid materials are easy to block and scale, and the heat exchange efficiency is thus improved. Thereby further improving the sterilization effect of high-viscosity fluid materials.

[0044] like Figure 5As shown, in some embodiments of the present invention, the first flow guide structure 4 includes a first flow guide protrusion 41 spirally distributed along the central axis of the first shell 1. Under the push of the first flow guide protrusion 41, on the one hand, the material in the corrugated channel 3 is in a turbulent state, which improves the heat exchange efficiency while accelerating the flow rate of the material and reducing the deposition and scaling of high-viscosity fluid materials. On the other hand, the high-viscosity fluid material in the corrugated channel 3 is pushed into a thin film. Under high-speed rotation, the material film will not be coked, which effectively improves the heat transfer efficiency and thus improves the sterilization effect.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a rotary ultra-high temperature sterilization device further includes a top shell 5, which is disposed on the top of the second shell 2 and is sealed and connected to the outer wall of the second shell 2. Preferably, the top shell 5 is a semicircular structure.

[0046] The feed port 31 of the corrugated channel 3 is communicated with the interior of the top shell 5, and a material inlet 51 is provided at the top of the top shell 5. A turbine 52 is provided in the top shell 5, and the turbine 52 is connected to the first shell 1. A hollow shaft 11 is provided in the first shell 1, and the hollow shaft 11 is connected to the turbine 52. A first heating structure is provided on the outside of the hollow shaft 11, and a plurality of small holes are provided on the outer wall of the hollow shaft 11. The interior of the hollow shaft 11 is communicated with the interior of the first shell 1 through the small holes, and a first inlet and outlet 12 is provided at the bottom of the hollow shaft 11.

[0047] Specifically, the turbine 52 is powered to rotate, and the turbine 52 is drivingly connected to the output shaft of the external motor. The turbine 52 is also drivingly connected to the hollow shaft 11, and the groove of the first housing 1 is connected to the hollow shaft 11, so that the rotation of the turbine 52 drives the hollow shaft 11 and the first housing 1 to rotate together.

[0048] During operation, high-viscosity fluid materials enter the top shell 5 from the material inlet 51 at the top of the top shell 5. Under the thrust of the turbine 52, the materials are stirred and quickly enter the corrugated channel 3, increasing the flow speed to avoid blockage caused by a large amount of feed.

[0049] Preferably, the first heating structure is arranged in the space formed between the hollow shaft 11 and the ridge of the first shell 1. The first fluid flows into the hollow shaft 11 from the first inlet and outlet 12, and then enters the interior of the first shell 1 through the small holes on the outer wall of the hollow shaft 11. The first heating structure continuously supplies heat to the first fluid to ensure the temperature in the first heat flow region 14, thereby exchanging heat with the material in the corrugated channel 3 to achieve a sterilization effect.

[0050] like Figure 1 and Figure 4As shown, in some embodiments of the present invention, a second heating structure is provided on the inner wall of the second shell 2. Preferably, the second heating structure is provided on the inner wall of the second shell 2 close to the corrugated channel 3. A second inlet and outlet 21 is provided at the bottom of the outer wall of the second shell 2, and the second fluid flows into the second shell 2 through the second inlet and outlet 21.

[0051] The second heating structure continuously supplies heat to the second fluid to ensure the temperature in the second heat flow region 23, thereby performing heat exchange on the material in the corrugated channel 3 to achieve a sterilization effect.

[0052] like Figure 1 and Figure 2 As shown, specifically, the first heating structure includes a plurality of groups of first resistance heating coils 13 evenly distributed along the central axis of the hollow shaft 11 , and each group of first resistance heating coils 13 is wound in a space formed between the hollow shaft 11 and the spine of the first shell 1 .

[0053] like Figure 1 and Figure 4 As shown, the second heating structure includes a second resistance heating coil 22 distributed in a spiral shape along the central axis of the second shell 2 to uniformly heat the second fluid in the second shell 2 to ensure the temperature in the second heat flow region 23 .

[0054] In some other embodiments of the present invention, the rotary ultra-high temperature sterilization device further includes a second flow guiding structure, which is arranged on the surface of the second shell 2 close to the first shell 1 and staggered with the first flow guiding structure 4 to avoid interference. In this embodiment, the second flow guiding structure is provided, and the first flow guiding structure 4 and the second flow guiding structure work together to further accelerate the flow rate of the material, reduce the deposition and scaling of high-viscosity fluid materials, and improve the heat exchange efficiency.

[0055] Specifically, the second flow guiding structure includes second flow guiding protrusions distributed in a spiral shape along the central axis of the second shell 2 .

[0056] In this embodiment, the top shell 5 is a semicircular structure. When the material enters the top shell 5, under the action of the turbine 52, the material will hit the wall of the top shell 5. When the top shell 5 is set as a semicircular structure, the material will flow into the corrugated channel 3 from the feed port 31 under the action of the arc slope. When the feed is large, the material will flow into the corrugated channel 3 under the action of the thrust of the turbine 52.
