Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable juice processing technology, specifically a low-temperature sterilization device for cold-pressed fruit and vegetable juice. Background Technology

[0002] The purpose of sterilizing fruit and vegetable juices is to prevent them from spoiling. Common sterilization methods include heat sterilization and non-heat sterilization. Heat sterilization includes high-temperature instantaneous sterilization, ultra-high-temperature instantaneous sterilization, and pasteurization, while non-heat sterilization includes physical sterilization and chemical sterilization.

[0003] When producing fruit and vegetable juices, sterilization is usually required. To preserve the nutrients in the juices, a low-temperature sterilization device, also known as pasteurization, is used. This process involves heating the juices to 70 degrees Celsius and maintaining that temperature for 30 minutes. However, existing low-temperature sterilization devices typically heat the inner wall of the tank and use stirring to distribute the heat evenly. This method has a simple structure, resulting in slow heat transfer between the juices and requiring a longer time to heat them to the specified temperature, thus affecting the sterilization efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a low-temperature sterilization device for cold-pressed fruit and vegetable juice, which has the advantage of high sterilization efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature sterilization device for cold-pressed fruit and vegetable juice, including a control console and a fixed frame, wherein a material tank is installed on the top of the fixed frame, and further includes a mixing structure, which is disposed on the material tank to ensure that the fruit and vegetable juice is heated evenly.

[0006] The mixing structure includes a first motor mounted on the top of the material tank. A stirring rod is mounted on the output shaft of the first motor. A heating assembly is located at the bottom of the inner cavity of the material tank. An installation platform is installed inside the material tank, with a slot inside the platform. A heat-conducting pipe is embedded on the outer surface of the installation platform. A return spring and a piston assembly are fitted inside the installation platform. A movable frame is mounted at the bottom end of the piston assembly. A first slot is located on the top of the installation platform, and a second slot is located on one side of the installation platform. A second motor is mounted on one side of the fixed frame, and a cam is mounted on the output shaft of the second motor.

[0007] Preferably, the reset spring is elastically supported between the mounting platform and the piston assembly.

[0008] Preferably, the movable frame is sleeved with the material tank, and the cam is in pressing contact with the movable frame.

[0009] Preferably, the bottom end of the heat-conducting pipe is connected to the mounting platform, and the top end of the heat-conducting pipe is connected to the material tank.

[0010] Preferably, a one-way valve is provided at the connection between the heat pipe and the mounting platform, as well as inside the second slot.

[0011] Preferably, the heat pipe is spiral-shaped, and the bottom of the heat pipe is in contact with the heating component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a second motor to control the rotation of a cam. Through the cooperation between the cam and the movable frame, the piston assembly moves along the inner wall of the mounting platform, causing the fruit and vegetable juice inside the tank to continuously flow into the mounting platform. At the same time, through the elastic force of the return spring, when the cam releases its pressure on the movable frame, it will drive the piston assembly to return to its original position, causing the piston assembly to squeeze the fruit and vegetable juice into the heat-conducting pipe and discharge it into the tank. As the fruit and vegetable juice passes through the heat-conducting pipe, it will absorb heat, thereby improving the efficiency of sterilization of the fruit and vegetable juice.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, this utility model provides a low-temperature sterilization device for cold-pressed fruit and vegetable juice, including a control console 1 and a fixing frame 2. A material tank 3 is installed on the top of the fixing frame 2. It also includes a mixing structure, which is set on the material tank 3 to make the fruit and vegetable juice heat evenly.

[0022] The mixing structure includes a first motor 4, which is mounted on the top of the material tank 3. The output shaft of the first motor 4 is equipped with a stirring rod 5. A heating component 6 is provided at the bottom of the inner cavity of the material tank 3. An installation platform 7 is installed inside the material tank 3. The installation platform 7 has a slot 8 inside. A heat-conducting pipe 12 is embedded on the outer surface of the installation platform 7. A return spring 9 and a piston assembly 10 are sleeved inside the installation platform 7. A movable frame 11 is installed at the bottom end of the piston assembly 10. A first slot 13 is opened on the top of the installation platform 7. A second slot 14 is opened on one side of the installation platform 7. A second motor 15 is installed on one side of the fixed frame 2. A cam 16 is installed on the output shaft of the second motor 15.

[0023] The operation of the second motor 15 will cause the cam 16 to rotate, thereby driving the piston assembly 10 to move along the inner wall of the mounting platform 7 through the cooperation between the cam 16 and the movable frame 11. When the piston assembly 10 moves along the inside of the mounting platform 7, a negative pressure will be formed below it, causing the fruit and vegetable juice inside the tank 3 to continuously flow into the inside of the mounting platform 7. At the same time, through the elastic force of the return spring 9, when the cam 16 releases the pressure on the movable frame 11, it will drive the piston assembly 10 to move downward, thereby squeezing the fruit and vegetable juice inside the mounting platform 7. Under the influence of the one-way valve, the fruit and vegetable juice will enter the heat conduction pipe 12 and be discharged back into the inside of the tank 3. When the fruit and vegetable juice passes through the heat conduction pipe 12, it will absorb heat, which can repeatedly heat the fruit and vegetable juice and increase the flow frequency of the fruit and vegetable juice, thereby improving the efficiency of sterilization of the fruit and vegetable juice.

[0024] The reset spring 9 is elastically supported between the mounting platform 7 and the piston assembly 10.

[0025] The design of the return spring 9 enables the piston assembly 10 to have good elastic return performance. Since the return spring 9 is in a compressed state, it will apply an elastic force to the piston assembly 10. When the cam 16 releases the pressure on the movable frame 11, it will drive the piston assembly 10 to squeeze the fruit and vegetable juice inside the mounting platform 7.

[0026] Among them, the movable frame 11 is sleeved with the material tank 3, and the cam 16 is in extrusion contact with the movable frame 11.

[0027] Through the cooperation between the movable frame 11 and the material tank 3, when the cam 16 is pressed against the movable frame 11, it will drive the movable frame 11 to move along the inner wall of the material tank 3, thereby driving the piston assembly 10 to move along the inner wall of the mounting platform 7 through the movable frame 11.

[0028] The bottom end of the heat pipe 12 is connected to the mounting platform 7, and the top end of the heat pipe 12 is connected to the material tank 3.

[0029] Through the cooperation between the heat pipe 12 and the mounting platform 7, when the piston assembly 10 moves downward, it will squeeze the fruit and vegetable juice inside the mounting platform 7, which will drive the fruit and vegetable juice into the interior of the heat pipe 12. As the fruit and vegetable juice flows along the interior of the heat pipe 12, the heat pipe 12 will heat the fruit and vegetable juice. At the same time, the fruit and vegetable juice will be discharged from the heat pipe 12 and flow back into the interior of the material tank 3.

[0030] One-way valves are installed at the connection between the heat pipe 12 and the mounting platform 7, as well as inside the second slot 14.

[0031] The one-way valve inside the second slot 14 allows the fruit and vegetable juice inside the tank 3 to enter the mounting platform 7 through the second slot 14. At the same time, the one-way valve between the heat conduction pipe 12 and the mounting platform 7 allows the fruit and vegetable juice to be discharged through the heat conduction pipe 12, preventing the fruit and vegetable juice inside the heat conduction pipe 12 from entering the mounting platform 7.

[0032] The heat pipe 12 is spiral-shaped, and the bottom of the heat pipe 12 is in contact with the heating component 6.

[0033] The design of the heat pipe 12, which is spiral in shape, can increase the time that fruit and vegetable juice flows along the inside of the heat pipe 12, thereby improving the heating efficiency. At the same time, through the cooperation between the heat pipe 12 and the heating component 6, the heating component 6 can heat the heat pipe 12.

[0034] Working principle and usage process of this utility model:

[0035] First, the second motor 15 controls the cam 16 to rotate, thereby driving the piston assembly 10 to move along the inner wall of the mounting platform 7 through the cooperation between the cam 16 and the movable frame 11. When the piston assembly 10 moves upward along the inside of the mounting platform 7, a negative pressure will be formed below it, causing the fruit and vegetable juice inside the tank 3 to continuously flow into the inside of the mounting platform 7. At the same time, through the elastic force of the return spring 9, when the cam 16 releases the pressure on the movable frame 11, it will drive the piston assembly 10 to move downward, causing it to squeeze the fruit and vegetable juice inside the mounting platform 7. Under the influence of the one-way valve, the fruit and vegetable juice will enter the heat conduction pipe 12. When the fruit and vegetable juice passes through the heat conduction pipe 12, it will be heated by the heat conduction pipe 12, which can repeatedly heat the fruit and vegetable juice and increase the flow frequency of the fruit and vegetable juice, thereby improving the efficiency of sterilization of the fruit and vegetable juice.
