[0001] The utility model relates to the technical field of fruit juice production, in particular to a high-voltage pulsed electric field sterilization device for fruit juice. Background Technique

[0002] With the improvement of people's living standards, people's material life is becoming more and more abundant. People have higher and higher requirements for the quality of food and beverages. The proportion of fruit juice in beverages is getting higher and higher. Fruit juice production is gradually tending towards large-scale industrial production. Disinfection and sterilization are means to ensure the quality of industrially produced fruit juice, and the efficiency of disinfection and sterilization must be guaranteed.

[0003] The existing mainstream disinfection and sterilization methods are as follows: (1) Ozone sterilization, that is, ozone is introduced into the fruit juice to sterilize the fruit juice. This method of fruit juice sterilization has a high cost and a large consumption of ozone, and is not suitable for large-scale fruit juice production. (2) High-temperature sterilization, that is, the fruit juice is heated to generate high temperature, and the characteristic of bacteria not being heat-resistant is used for sterilization. However, this method has high requirements for temperature control. If not mastered well, it will cause the fruit juice to deteriorate, and the taste of the heated fruit juice is not good.

[0004] Therefore, a high-voltage pulsed electric field sterilization device for fruit juice is proposed. Using high-voltage pulsed electric field for sterilization not only meets the requirements of large-scale production, but also avoids heating the fruit juice, and can effectively retain the original taste of the fruit juice.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 3 , the present invention provides a high-voltage pulsed electric field sterilization device for fruit juice, and the technical solution is as follows:

[0023] A high-voltage pulsed electric field sterilization device for fruit juice includes a first frame 1, a liquid inlet tank 2, a liquid outlet tank 3, and a second frame 5. The liquid inlet tank 2 is fixedly installed on the top wall of the first frame 1, the liquid outlet tank 3 is placed at the bottom of the first frame 1, the second frame 5 is placed on one side of the first frame 1, the top of the first frame 1 is higher than the top of the second frame 5, both the liquid outlet tank 3 and the liquid inlet tank 2 have been sterilized, the liquid inlet tank 2 is used to store the fruit juice liquid to be sterilized, the liquid outlet tank 3 is used to receive the fruit juice liquid after sterilization, and the controller 4 is fixedly installed in the middle of the first frame 1.

[0024] As Figure 1 shown, a plurality of conductive cooling pipes are fixedly installed on the top wall of the second frame 5. An outlet 8 is provided on the side wall of the liquid inlet tank 2, and a liquid inlet pipe 7 is connected to the outlet 8. One end of the liquid inlet pipe 7 communicates with a plurality of the conductive cooling pipes, and a liquid outlet pipe 9 is provided on each of the plurality of conductive cooling pipes and communicates with the liquid outlet tank 3. Since the liquid inlet tank 2 is located at a high place, the fruit juice liquid in the liquid inlet tank 2 automatically flows into the liquid inlet pipe 7 under the traction of gravity and enters the conductive cooling pipes. The conductive cooling pipes are connected to the controller 4 through wires. The controller 4 controls the conductive cooling pipes to generate a high-voltage pulsed electric field, and uses the high-voltage pulsed electric field to sterilize the fruit juice liquid flowing into the conductive cooling pipes. After sterilization, the fruit juice liquid flows through the liquid outlet pipe 9 to the liquid outlet tank 3 for storage.

[0025] As Figure 2As shown in the figure, the conductive cooling tube includes a housing 6, a second housing 13, and electrode rods 14. The housing 6 is fixedly installed on the top wall of the second frame 5. The second housing 13 is fixedly installed inside the housing 6. The electrode rods 14 are fixedly installed inside the second housing 13. An interface 10 is provided on the side wall of the housing 6 to dock with the liquid inlet pipe 7. The interface 10 communicates with the inside of the second housing 13. A liquid channel is formed between the electrode rods 14 and the second housing 13. Fruit juice liquid flows into the liquid channel. The electrode rods 14 are provided with positive and negative electrodes and are electrically connected to the controller 4. The controller 4 delivers a high-voltage current to the electrode rods 14 to generate a high-voltage pulsed electric field in the liquid channel, thereby achieving a sterilization effect.

[0026] As Figure 2 shown, an interface 11 is provided on the side wall of the housing 6 away from the interface 10 to dock with the liquid outlet pipe 9. The interface 11 communicates with the inside of the second housing 13. The fruit juice liquid after being sterilized by the high-voltage pulsed electric field flows into the liquid outlet pipe 9 through the interface 11 and then into the liquid outlet tank 3.

[0027] A refrigerator 16 is also fixedly installed in the middle of the first frame 1. The refrigerator 16 is located on one side of the controller 4. The refrigerator 16 is controlled by the controller 4. An air inlet channel is provided between the housing 6 and the second housing 13. An air inlet 12 and an air outlet 15 are provided on the side wall of the housing 6. Both the air inlet 12 and the air outlet 15 are connected to the refrigerator 16 through pipes. The controller 4 controls the electric field strength of the electrode rods 14 and controls the temperature of the gas delivered by the refrigerator 16 into the air inlet channel. Since the high-voltage pulsed electric field sterilization process will cause the fruit juice liquid to generate heat and cold and the temperature will rise, equipped with cold air can cool down while sterilizing to achieve a good sterilization effect.

[0028] A solenoid valve is also provided at the liquid outlet 8, and a solenoid valve is also provided at each interface 11. Each solenoid valve is electrically connected to the controller 4.

[0029] The controller 4 controls the amount of liquid entering the second housing 13 by controlling the solenoid valve at the liquid outlet 8. The controller 4 controls the opening and closing time lengths of the solenoid valves at the interfaces 11. The closing time of the solenoid valves at the interfaces 11 is the same as the energization time of the electrode rods 14.
