Description

Technical Field

[0001] This utility model relates to the field of ultra-high temperature sterilization, and in particular to an ultra-high temperature sterilization device for milk and soft drinks. Background Technology

[0002] Ultra-high temperature sterilization devices refer to high-temperature sterilizers, which are usually tubular, plate, or tubular-plate combinations. They can heat milk and soft drinks to 135-150°C in a short time and maintain the temperature for several seconds. This high-temperature, short-time sterilization method can quickly kill various microorganisms, including Bacillus, greatly improving the microbial safety of the product and extending its shelf life.

[0003] In existing technologies, the beverage is discharged directly along the sterilization pipe during the sterilization process. However, this method has the following drawbacks in actual use: the beverage moves in a laminar flow, resulting in poor distribution. The central area is prone to not reaching a good sterilization temperature, creating sterilization dead zones. Furthermore, the flow velocity on the outer side is fixed and not easily adjustable, resulting in poor adaptability. In addition, the area in contact with the inner wall of the pipe is prone to overheating and charring, affecting the taste of the beverage.

[0004] Therefore, an ultra-high temperature sterilization device for milk and soft drinks is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-high temperature sterilization device for milk and soft drinks to solve the above-mentioned problems, thereby improving the problems of sterilization dead zones, fixed flow rate leading to poor adaptability and easy overheating and caramelization of beverages.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: an ultra-high temperature sterilization device for milk and soft drinks, comprising a sterilizer body and a sterilization pipeline installed on its outer side; it also includes an adjustment mechanism, which is disposed inside the sterilization pipeline and is used to adjust the flow rate and flow pattern of the beverage; wherein, the adjustment mechanism includes an adjustable flow guide shroud and a spiral blade disposed on its outer side, an adjustment cone is installed on the side of the spiral blade near the flow guide shroud, and a through groove aligned with the adjustment cone is opened inside the flow guide shroud.

[0007] Preferably, a connecting shaft runs through the interior of the helical blade, and a set of conical discs are sleeved on the outside of the connecting shaft. A set of threaded grooves are opened on the outside of the conical discs, and the size of the set of conical discs gradually decreases in the direction away from the helical blade.

[0008] Preferably, the sterilization pipeline includes a sterilization pipe and a heat transfer pipe sleeved to its outside, and the spiral blades and the flow guide are both disposed inside the sterilization pipe.

[0009] Preferably, a cross shaft is installed at one end of the connecting shaft, and a ball bearing is provided at the end of the cross shaft. The cross shaft is rotatably connected to the inside of the sterilization pipe through the ball bearing.

[0010] Preferably, a toothed plate is installed on the outer side of the flow guide shroud, a gear is meshed on the toothed plate, and a rotating shaft is installed on one side of the gear, extending sequentially to the outer side of the sterilization pipe and the heat transfer pipe.

[0011] Preferably, a servo motor is installed on the outside of the heat transfer pipe, and the output shaft of the servo motor is fixedly connected to one end of the rotating shaft through a coupling.

[0012] Preferably, the connection between the sterilization pipe, the heat transfer pipe and the rotating shaft is treated with a rotary seal.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a flow guide, the beverage can be pressurized and guided, allowing it to pass through the sterilization section quickly, reducing the occurrence of overheating and charring, and ensuring the taste of the beverage. Then, by setting up spiral blades, the laminar flow is transformed into spiral flow, reducing the amount of beverage in the central area during the flow process, ensuring the transfer of sterilization temperature, and reducing sterilization dead zones.

[0015] 2. By setting up a toothed plate and gears, the position of the flow guide can be changed through the transmission of the two, so that the adjusting cone is placed inside the through groove, thereby changing the liquid flow rate and thus changing the subsequent flow rate. This allows for corresponding adjustments according to the type of beverage, making it more adaptable. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figures 1-4 As shown, an ultra-high temperature sterilization device for milk and soft drinks includes a sterilizer body 100 and a sterilization pipeline 200 installed on its outside; it also includes an adjustment mechanism 300, which is disposed inside the sterilization pipeline 200 and is used to adjust the flow rate and flow pattern of the beverage; wherein, the adjustment mechanism 300 includes an adjustable flow guide shroud 310 and a spiral blade 320 disposed on its outside, an adjustment cone 321 is installed on the side of the spiral blade 320 near the flow guide shroud 310, and a through groove aligned with the adjustment cone 321 is opened inside the flow guide shroud 310.

[0023] like Figure 3 and Figure 4 As shown, a connecting shaft 322 runs through the interior of the spiral blade 320. A set of conical discs 323 are sleeved on the outside of the connecting shaft 322. A set of threaded grooves are opened on the outside of the conical discs 323. The size of the set of conical discs 323 gradually decreases in the direction away from the spiral blade 320.

[0024] When the beverage is introduced into the sterilization pipeline 200, the flow guide 310 guides the beverage, changing it from a large path flow to a small path flow, thereby achieving a pressurization effect. Then, the liquid is divided by the adjusting cone 321. Next, the rotating spiral blades 320 convert the laminar liquid into a spiral flow. During the rotation of the spiral blades 320, the connecting shaft 322 can be driven to move, thereby causing the cross shaft 324 and the conical disk 323 to move synchronously. Subsequently, the liquid changes from a large volume flow to a small volume flow and is pressurized, thereby achieving a flow rate increase effect. This effectively reduces the occurrence of liquid overheating and charring. During the flow, the liquid flows rapidly along the inner wall of the sterilization pipeline 210, which can ensure the sterilization temperature transfer and reduce sterilization dead zones. Subsequently, during the spiral flow of the liquid, a set of conical disks 323 with threaded grooves is used to compensate for the swirling attenuation. The gradually decreasing size of the conical disks reduces liquid obstruction and ensures that the liquid passes through the sterilization pipeline 210 smoothly and quickly.

[0025] When sterilizing different types of beverages, the flow rate can be adjusted according to the beverage. The user can drive the flow guide shroud 310 to move, so that the adjusting cone 321 is placed inside the channel, thereby changing the liquid discharge in the channel and completing the flow rate adjustment.

[0026] It should be noted that the sterilizer body 100 used in this application is a tube-plate combined sterilizer, specifically model PT-20C. This equipment is a mature existing technology, and its specific internal structure and practical application will not be described in detail here.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the sterilization pipeline 200 includes a sterilization pipeline 210 and a heat transfer pipeline sleeved to its outside. The spiral blade 320 and the flow guide shroud 310 are both disposed inside the sterilization pipeline 210.

[0028] A heat source is introduced through a heat transfer pipe, so that the heat energy is transferred to the sterilization pipe 210, thereby sterilizing the beverage inside the sterilization pipe 210.

[0029] like Figure 3 As shown, a cross shaft 324 is installed at one end of the connecting shaft 322, and a ball bearing is provided at the end of the cross shaft 324. The cross shaft 324 is rotatably connected to the inside of the sterilization pipe 210 through the ball bearing.

[0030] A cross shaft 324 is used to support the connecting shaft 322. During rotation, a ball bearing can be used to reduce wear between the cross shaft 324 and the sterilization pipe 210, ensuring smooth rotation and extending the service life of the equipment.

[0031] like Figure 4 As shown, a toothed plate 311 is installed on the outer side of the flow guide shroud 310, and a gear 312 is meshed on the toothed plate 311. A rotating shaft is installed on one side of the gear 312, extending sequentially to the outside of the sterilization pipe 210 and the heat transfer pipe.

[0032] When adjusting the flow rate, the gear 312 can be driven to rotate, causing the toothed plate 311 to follow the movement, thereby adjusting the position of the flow guide shroud 310 and completing the adjustment operation.

[0033] like Figure 2 and Figure 3 As shown, a servo motor 400 is installed on the outside of the heat transfer pipe, and the output shaft of the servo motor 400 is fixedly connected to one end of the rotating shaft through a coupling.

[0034] Starting the servo motor 400 will drive the rotating shaft to move, which in turn drives the gear 312 to move the gear plate 311, causing the relative position of the guide shield 310 and the adjusting cone 321 to change, thus achieving the adjustment effect.

[0035] like Figure 3 and Figure 4 As shown, the connection between the sterilization pipe 210, the heat transfer pipe and the rotating shaft is treated with a rotary seal.

[0036] By using a rotary seal, the accidental leakage of heat sources and beverages during the flow process can be reduced.

[0037] Working Principle: In the sterilization process, after plate sterilization on the sterilizer body 100, the beverage is introduced into the sterilization pipeline 200 for secondary sterilization. When the beverage is introduced into the sterilization pipeline 200, the flow guide 310 guides the flow, changing it from a large path to a small path, thus achieving a pressurization effect. Then, the adjusting cone 321 divides the liquid flow, followed by rotating spiral blades 320 that transform laminar flow into spiral flow. The liquid then changes from a large volume flow to a small volume flow and is pressurized, thus increasing the flow rate and effectively reducing the occurrence of overheating and charring. During the flow, the liquid flows rapidly along the inner wall of the sterilization pipeline 210, ensuring heat transfer and reducing sterilization dead zones. Subsequently, during the spiral flow of the liquid, a set of threaded grooves... The conical disc 323 compensates for swirling attenuation and uses a gradually decreasing size to reduce liquid obstruction, ensuring smooth and rapid passage of liquid through the sterilization pipe 210. When it is necessary to adjust the flow rate to sterilize different types of beverages, the user can drive the servo motor 400 to rotate the shaft and the gear 312. Then, the toothed plate 311 drives the guide shroud 310 to move, causing the adjusting cone 321 to be placed inside the channel, thereby changing the amount of liquid discharged in the channel and completing the flow rate adjustment. The entire device makes the beverage flow in a spiral manner, reducing the amount of beverage in the central area during the flow, ensuring the transmission of sterilization temperature, reducing sterilization dead zones, and allowing for diverse flow rate adjustments according to the type of beverage, making it more adaptable. Increasing the flow rate can enhance the speed at which the beverage passes through the sterilization section, reducing the phenomenon of overheating and charring, and ensuring the taste of the beverage.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
