Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to a pasteurization machine. Background Art

[0002] There are many bacteria in the newly collected emulsion, which will not only pollute and corrupt the emulsion, but some pathogens will also cause various diseases. Therefore, the emulsion will be sterilized by high temperature and other means before consumption, but high temperature often denatures some proteins in the emulsion, making the taste of the emulsion worse and losing nutrients. Therefore, pasteurization is used for industrial sterilization. Pasteurization is also called pasteurization. In 1862, Pasteur invented a disinfection method that can kill bacteria in the emulsion but does not affect the taste of the emulsion, namely pasteurization. Compared with conventional disinfection methods, the main difference of pasteurization is that the temperature is controlled at around 70°C, so that the temperature of the emulsion is not too high, retaining the taste and nutrition, and removing many harmful bacteria.

[0003] The existing pasteurization machine heats the emulsion for a certain period of time and then needs to be cooled before collection. Not only does it consume a lot of energy to cool the emulsion, but the waiting time is also long, resulting in poor sterilization efficiency. Utility Model Content

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] according to Figure 1-2 The utility model provides a pasteurization machine, comprising: a sterilization tank 1, a cooling tank 2, a delivery pipe 3, an output pipe 4, a water inlet pipe 5, a liquid level meter 6, a heater 7, and an input pipe 8.

[0017] The heater extends into the sterilizing tank 1. The input pipe 8 is connected to the sterilizing tank 1. The liquid level meter 6 includes: a display tube 61 and a connecting pipe 62. There are two connecting pipes 62. The two connecting pipes 62 are respectively arranged on both sides of the display tube. The outside of the connecting pipe 62 is a heat-insulating material. One end of the connecting pipe 62 is connected to the display tube 61, and the other end is connected to the sterilizing tank 1. The display tube 61 is a double-layer glass with a vacuum in the middle.

[0018] During sterilization, the emulsion is transported from the input pipe 8 to the sterilization tank 1. At this time, the emulsion will also flow from the connecting pipe 62 to the display tube 61 of the liquid level gauge 6. Since the liquid level gauge 6 has two connecting pipes 62 connected to the sterilization tank 1, the pressure inside the liquid level gauge 6 and the sterilization tank 1 are kept consistent, that is, the liquid level of the liquid level gauge 6 is the same as the liquid level of the sterilization tank 1. Therefore, the liquid level of the emulsion in the sterilization tank 1 can be determined according to the liquid level of the emulsion in the display tube 61.

[0019] After the delivery is completed, the input pipe 8 is closed and the heater 7 is turned on to heat the inside of the sterilization tank 1. After the temperature rises to about 70°C, the constant temperature is maintained. Since the display tube 61 is a double-layer glass with a middle vacuum and the connecting tube 62 is a heat-insulating material, the emulsion can be kept warm even in the liquid level meter 6 to prevent a large amount of heat loss during the sterilization process.

[0020] A cavity 21 is formed inside the cooling tank 2. A cooling pipe 22 is provided inside the cooling tank 2. The cooling pipe 22 passes through the cavity 21. The water inlet pipe 5 is connected to the cavity 21. One end of the cooling pipe 22 is connected to the sterilizing tank 1, and the other end is connected to the output pipe 4. A valve is provided at the connection between the sterilizing tank 1 and the cooling pipe 22. A delivery pump 31 is provided on the delivery pipe 3. One end of the delivery pipe 3 is connected to the cavity 21, and the other end is connected to the sterilizing tank 1. The cooling pipe 22 is a spiral structure.

[0021] Before the sterilization is started, cold clean water can be introduced into the cavity 21 in the cooling tank 2 from the water inlet pipe 5. After the emulsion is sterilized in the sterilization tank 1, the valve at the connection between the sterilization tank 1 and the cooling pipe 22 is opened, and the emulsion flows from the sterilization tank 1 into the cooling pipe 22. Since the cooling pipe 22 is a spiral structure, the emulsion flows in the cooling pipe 22 for a long time, and the cooling pipe 22 contacts the cold water in the cavity 21, which accelerates the cooling of the emulsion, so that the emulsion can be effectively cooled in the cooling pipe 22, and finally flows out from the output pipe 4.

[0022] The sterilizing tank 1 includes: an agitator 11 and a sterilizing cover 12. The agitator 11 includes: a motor 111, a rotating rod 112, and a stirring rod 113. The sterilizing cover 12 is arranged at the end of the sterilizing tank 1 away from the cooling tank 2. The motor 111 is arranged at the end of the sterilizing cover 12 away from the cooling tank 2. The rotating rod 112 is arranged inside the sterilizing tank 1. The rotating rod 112 is connected to the motor 111. The stirring rod 113 is arranged at the side of the rotating rod 112 away from the motor 111. There are two stirring rods 113. The stirring rod 113 is arranged along the side of the rotating rod 112 away from the motor 111 to the side close to the motor 111. The two stirring rods 113 are perpendicular to each other.

[0023] When the emulsion is placed in the sterilizing tank 1 for heating, the motor 111 of the stirrer 11 can be turned on, so that the stirring rod 113 stirs in the sterilizing tank 1, so that the emulsion flows in the sterilizing tank 1, so that all the emulsion can fully contact the heater 7, and the heating is ensured to be uniform. Avoid the situation that the temperature of the emulsion close to the heat source is higher and the temperature of the emulsion far from the heat source is lower during heating, resulting in greater energy consumption when the sterilization requirement is met. The utility model is provided with two stirring rods 113, which are arranged from one end of the rotating rod 112 to the other end, and the stirring rods 113 are perpendicular to each other, so that the emulsion can be stirred in a larger space, so that the stirring is more sufficient.

[0024] In addition, after the emulsion is cooled, close the valve between the sterilization tank 1 and the cooling pipe 22, open the delivery pump 31 of the delivery pipe 3, so that clean water can flow from the delivery pipe 3 into the sterilization tank 1, open the sterilization cover 12, add the cleaning agent into the sterilization tank 1, close the sterilization cover 12 and the delivery pump 31, start the agitator 11 to accelerate the cleaning of the sterilization tank 1, open the valve again, so that the cleaning agent can also clean it through the cooling pipe 22, and finally open the delivery pump 31 to rinse the sterilization tank 1 and the cooling pipe 22.

[0025] The working principle and use process of this utility model:

[0026] When the utility model is in use, the valve between the sterilizing tank 1 and the cooling pipe 22 is first closed, and the emulsion to be sterilized is introduced into the sterilizing tank 1 from the input pipe 8. After observing from the liquid level gauge 6 that the emulsion reaches the specified liquid level, the input pipe 8 is closed, the heater 7 is turned on to heat the emulsion, and then the motor 111 of the stirrer 11 is turned on to drive the rotating rod 112 to rotate, and then the stirring rod 113 is driven to stir the emulsion. After the heater 7 heats the emulsion to about 70°C, the heating is stopped to maintain a constant temperature. After waiting for about half an hour, the heater 7 is turned off, cold water is introduced into the cavity 21 from the water inlet pipe 5, and the valve is opened to allow the emulsion with a higher temperature to enter the cooling pipe 22. The emulsion flows in the cooling pipe 22 and is gradually cooled and cooled, and finally discharged from the output pipe 4. After that, the valve can be closed, and the delivery pump 31 can be opened to allow cold water to flow from the delivery pipe 3 into the sterilization tank 1. After the water level in the liquid level gauge 6 reaches a certain height, the delivery pump 31 can be closed, the sterilization cover 12 can be opened, and an appropriate amount of cleaning agent can be added to the sterilization tank 1. The sterilization cover 12 can be closed, and the agitator 11 can be opened to clean the sterilization tank 1. After cleaning, the valve can be opened to allow the cold water mixed with the cleaning agent to enter the cooling pipe 22 and clean the cooling pipe 22. The delivery pump 31 can be opened again to allow the cold water to enter the sterilization tank 1 and the cooling pipe 22 again, and the sterilization tank 1 and the cooling pipe 22 can be rinsed.

[0027] In summary, the utility model is provided with a spiral cooling pipe connected to the sterilizing tank, and a cavity connected to the outer wall of the cooling pipe is provided, so that a low-temperature medium can be added to accelerate the cooling of the emulsion. Therefore, only cold water and a long cooling pipe are needed to cool the emulsion, and the energy consumption is low. After all the emulsion is passed into the cooling pipe, the valve can be closed to pass new emulsion for sterilization, and the waiting time is short.
