Description

Technical Field

[0001] This utility model relates to the field of sterilization machine technology, and in particular to a tubular sterilization machine with discharge temperature control. Background Technology

[0002] Tubular UHT sterilizers can completely simulate industrial production conditions, including preheating, heating, water cooling, and ice cooling stages. Currently, tubular sterilizers are mainly divided into three types: multi-layer tube-casing type, double-layer tube-casing type, and shell-and-tube type. They can be used for high-temperature instantaneous sterilization of products such as milk, dairy beverages, fruit juice, tomato sauce, condiments, additives, tea beverages, beer, cream, butter, and ice cream. Because dairy products contain relatively rich nutrients such as protein and starch, these substances are prone to coking and gelatinization during heating, easily forming scale on the side tube walls of the shell-and-tube sterilizer. This severely affects the heat exchange efficiency of the sterilizer, increases the cleaning frequency, and impacts production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a tubular sterilizer with discharge temperature control to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A tubular sterilizer with discharge temperature control includes a workbench, a first pipe, a second pipe, and a sterilization pipe module. A fixed support is provided on the top of the workbench, and multiple rows of heat exchange pipes are arranged at equal intervals from top to bottom on the fixed support. The first pipe passes through the heat exchange pipe located in the top row, and the second pipe passes through the remaining multiple rows of heat exchange pipes in sequence. A funnel is fixedly installed on the top of the workbench, and an infusion pump is fixedly installed at the inner bottom of the workbench. The inlet of the infusion pump is connected to the bottom of the funnel through a pipe, and the outlet of the infusion pump is connected to the inlet of the second pipe.

[0006] By adopting the above technical solution, the liquid to be sterilized is carried by the first pipe into the uppermost heat exchange pipe, and then enters the funnel from the outlet of the first pipe. Then, the infusion pump draws the liquid from the bottom of the funnel and sends it into the second pipe. Sterilization is then carried out in the multi-row heat exchange pipe. Because the liquid is heated and sterilized in stages through two pipes, it is relatively easy to control the temperature. The first pipe is the end of the sterilization path, so ultra-high temperature can be used to rapidly sterilize the liquid flowing in the first pipe. Then, through the cooperation of the second pipe and the other multi-row heat exchange pipes, long-term sterilization of the liquid is achieved, and temperature control is implemented. This ensures that the sterilization effect is better after passing through the first pipe. In the second pipe, the sterilization temperature of the first pipe can be used to achieve a better temperature control effect for the passage time. While ensuring the sterilization effect, it is also less likely to cause coking or gelatinization problems.

[0007] In a further embodiment, the multiple rows of heat exchange pipes have the same structure. Each row of heat exchange pipes includes a first straight pipe, a second straight pipe, a third straight pipe, a fourth straight pipe, a first bend, a second bend, and a third bend. The first straight pipe, the second straight pipe, the third straight pipe, and the fourth straight pipe are arranged at equal intervals from front to back. The first bend is used to connect the first straight pipe and the second straight pipe. The second bend is used to connect the second straight pipe and the third straight pipe. The third bend is used to connect the third straight pipe and the fourth straight pipe. The first bend and the third bend are both located on the left side, and the second bend is located on the right side. The outer sides of the first straight pipe, the second straight pipe, the third straight pipe, and the fourth straight pipe are all fitted with heat insulation sleeves.

[0008] In a further embodiment, the first straight pipe, the second straight pipe, the third straight pipe, and the fourth straight pipe are all provided with end caps at both ends, and each end cap is provided with a shaft hole, and a sealing ring is installed in the shaft hole. The first pipe passes through the first straight pipe, the second straight pipe, the third straight pipe, and the fourth straight pipe in the uppermost row of heat exchange pipes in sequence.

[0009] By adopting the above technical solution, the sealing ring can seal the end cap through which the first pipe passes, preventing leakage from the heat exchange pipeline composed of the first straight pipe, second straight pipe, third straight pipe, fourth straight pipe, first bend pipe, second bend pipe, and third bend pipe. A pipe joint communicating with the interior of the first straight pipe is provided at the rear right end, and a pipe joint communicating with the interior of the fourth straight pipe is provided at the front right end. These two pipe joints achieve the purpose of increasing the heat exchange medium inside the heat exchange pipeline composed of the first straight pipe, second straight pipe, third straight pipe, fourth straight pipe, first bend pipe, second bend pipe, and third bend pipe. The high-temperature fluid medium enters the interior of the fourth straight pipe from the pipe joint, then sequentially passes through the third bend pipe, third straight pipe, second bend pipe, second straight pipe, first bend pipe, and first straight pipe, finally flowing out from the pipe joint of the first straight pipe.

[0010] In a further embodiment, the heat exchange pipes are arranged in five rows.

[0011] By adopting the above technical solution, the top row of heat exchange pipes is used for high-temperature sterilization of the liquid inside the first pipe, and the remaining four rows of heat exchange pipes below are used for high-temperature sterilization of the liquid inside the second pipe. Therefore, the second pipe enters from the right end of the fourth pipe of the bottom heat exchange pipe, and then flows out from the right end of the first straight pipe of the bottom heat exchange pipe; then it enters the first straight pipe of the second row of heat exchange pipes from bottom to top, and finally exits from the fourth straight pipe of the second row; it enters again from the right end of the fourth straight pipe of the third row of heat exchange pipes from bottom to top, and exits from the right end of the first straight pipe of the third row; finally, it enters from the right end of the first straight pipe of the fourth row of heat exchange pipes from bottom to top, and finally exits from the right end of the fourth straight pipe of the fourth row of heat exchange pipes.

[0012] In a further embodiment, a replenishing pipe is provided on the top of the workbench for replenishing the inside of the hopper; a drain pipe is provided on the top of the workbench, the top end of the drain pipe is connected to the top of the inside of the funnel, and the bottom end of the drain pipe is connected to a collection bucket.

[0013] By adopting the above technical solution, when the liquid inside the hopper is insufficient, liquid is added to the hopper through the replenishment pipe. When the liquid level inside the hopper is higher than the set height, due to atmospheric pressure, the liquid above the set liquid level will enter the interior of the drain pipe, preventing liquid from overflowing to the top of the workbench. Because the disinfection setting uses two sets of pipes, the first pipe and the second pipe, there will be a flow rate difference between the two sets of pipes, which will result in the problem of excess or insufficient liquid. Therefore, a funnel is needed as a buffer connecting the first pipe and the second pipe, so it is necessary to replenish or drain the liquid inside the funnel.

[0014] In a further embodiment, the workbench is equipped with at least two temperature control modules.

[0015] In a further embodiment, a control terminal is provided on the top of the workbench.

[0016] By adopting the above technical solution, the temperature control module is a conventional central heat exchanger, which is used to provide heat exchange medium to each row of heat exchange pipes separately. The reason for setting at least two is that there are two sets of pipe systems (first pipe and second pipe), which require different temperatures, so they need to be controlled separately. The control terminal is used to cooperate with the temperature control module to provide heat exchange medium of different temperatures to each row of heat exchange pipes.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. The liquid requiring sterilization is drawn into the top row of heat exchange pipes by the first pipe, and then enters the funnel from the outlet of the first pipe. The infusion pump then draws the liquid from the bottom of the funnel and sends it into the second pipe. Sterilization then takes place in the multi-row heat exchange pipes. Because the liquid is heated and sterilized in stages through two pipes, the temperature is relatively easy to control. The first pipe is the end of the sterilization path, so ultra-high temperature can be used to rapidly sterilize the liquid flowing through it. Then, through the second pipe and the other multi-row heat exchange pipes, long-term sterilization of the liquid is achieved, and temperature control is maintained. This ensures that the sterilization effect is good after passing through the first pipe, and the sterilization temperature in the second pipe can be used to achieve good temperature control over the passage time. This ensures the sterilization effect and prevents problems such as coking and gelatinization. Attached Figure Description

[0025] Example 1:

[0026] like Figures 1-3As shown, a tubular sterilizer with discharge temperature control includes a workbench 1, a first pipe 2, a second pipe 3, and a sterilization pipe module 4. A fixed support is installed on the top of the workbench 1, and multiple rows of heat exchange pipes 41 are arranged at equal intervals from top to bottom on the fixed support. These multiple rows of heat exchange pipes 41 form the sterilization pipe module 4. The first pipe 2 passes through the top row of heat exchange pipes 41, and the second pipe 3 passes through the remaining multiple rows of heat exchange pipes 41 sequentially. A funnel 5 is fixedly installed on the top of the workbench 1, and an infusion pump is fixedly installed at the inner bottom of the workbench 1. The inlet of the infusion pump is connected to the bottom of the funnel 5 through a pipe, and the outlet of the infusion pump is connected to the inlet of the second pipe 3. The multiple rows of heat exchange pipes 41 have identical structures, with each row of heat exchange pipes 41... Each pipe includes a first straight pipe 411, a second straight pipe 412, a third straight pipe 413, a fourth straight pipe 414, a first bend 415, a second bend 416, and a third bend 417. The first straight pipe 411, second straight pipe 412, third straight pipe 413, and fourth straight pipe 414 are arranged at equal intervals from front to back. The first bend 415 connects the first straight pipe 411 and the second straight pipe 412; the second bend 416 connects the second straight pipe 412 and the third straight pipe 413; and the third bend 417 connects the third straight pipe 413 and the fourth straight pipe 414. The first bend 415 and the third bend 417 are located on the left side, and the second bend 416 is located on the right side. The first straight pipe 411, second straight pipe 412, third straight pipe 413, and fourth straight pipe 414 are arranged at equal intervals from front to back. Insulating sleeves are fitted around the outside of each of the four pipes. End caps are installed at both ends of the first straight pipe 411, the second straight pipe 412, the third straight pipe 413, and the fourth straight pipe 414. Shaft holes are opened on the end caps, and sealing rings are installed inside the shaft holes. The first pipe 2 passes sequentially through the first straight pipe 411, the second straight pipe 412, the third straight pipe 413, and the fourth straight pipe 414 of the uppermost row of heat exchange pipes 41. There are five rows of heat exchange pipes 41. The uppermost row of heat exchange pipes is used for high-temperature sterilization of the liquid inside the first pipe, and the remaining four rows of heat exchange pipes are used for high-temperature sterilization of the liquid inside the second pipe. Therefore, the second pipe enters from the right end of the fourth pipe of the lowermost heat exchange pipe and exits from the right end of the first straight pipe of the lowermost heat exchange pipe. Then it enters the first straight pipe of the second row of heat exchange pipes from the bottom up, and finally exits from the fourth straight pipe of the second row; it enters again from the right end of the fourth straight pipe of the third row of heat exchange pipes from the bottom up, and exits from the right end of the first straight pipe of the third row; finally, it enters from the right end of the first straight pipe of the fourth row of heat exchange pipes from the bottom up, and finally exits from the right end of the fourth straight pipe of the fourth row of heat exchange pipes; a liquid replenishment pipe 6 is provided on the top of the workbench 1, which is used to replenish the liquid inside the hopper; a drain pipe is provided on the top of the workbench 1, the top end of which is connected to the top of the inside of the funnel 5, and the bottom end of which is connected to the collection bucket; at least two temperature control modules are provided inside the workbench 1; a control terminal is provided on the top of the workbench 1.

[0027] Specific implementation process: The liquid to be sterilized is carried by the first pipe into the top row of heat exchange pipes, and then enters the funnel from the outlet of the first pipe. Then, the infusion pump draws the liquid from the bottom of the funnel and sends it into the second pipe. Sterilization is then carried out in the multi-row heat exchange pipes. Because the liquid is heated and sterilized in stages through two pipes, the temperature is relatively easy to control. The first pipe is the end of the sterilization path, so ultra-high temperature can be used to quickly sterilize the liquid flowing in the first pipe. Then, through the second pipe and the other multi-row heat exchange pipes, long-term sterilization of the liquid is achieved, and temperature control is implemented. This ensures that the sterilization effect is better after passing through the first pipe, and the sterilization temperature in the second pipe can be used to achieve a better temperature control effect for the passage time. While ensuring the sterilization effect, it is also less likely to cause coking or gelatinization problems.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
