Description

Technical Field

[0001] This utility model relates to the technical field of fruit juice sterilization devices, and in particular to a fruit juice sterilization device. Background Technology

[0002] With the increasing health awareness of global consumers, fruit juice, rich in nutrients such as vitamins, minerals and dietary fiber, has become an important part of the food and beverage market. In the production process of fruit juice, sterilization is a key step to ensure the quality of fruit juice and extend its shelf life, thereby preventing the fruit juice from deteriorating in quality such as taste changes, discoloration, separation, and sedimentation, thus extending the shelf life of the fruit juice and improving the stability of its quality.

[0003] Most existing fruit juice sterilization devices rely on a single high-temperature structure for sterilization, resulting in a longer heat transfer path, slower fruit juice heating, and prolonged sterilization time, thus impacting production efficiency. Furthermore, the lack of an efficient radial stirring structure makes it difficult to break up temperature stratification in the fruit juice, easily creating sterilization dead zones and leading to incomplete sterilization in certain areas. Therefore, to address the problems of most existing fruit juice sterilization devices relying on a single high-temperature structure for sterilization, resulting in a longer heat transfer path, slower fruit juice heating, and prolonged sterilization time, thus affecting production efficiency, a new fruit juice sterilization device can be designed. Utility Model Content

[0004] To overcome the problem that most fruit juice sterilization devices rely on a single high-temperature structure to sterilize fruit juice, resulting in a longer heat transfer path, slower fruit juice heating, and a forced extension of sterilization time, thus affecting production efficiency, a new fruit juice sterilization device is proposed.

[0005] The technical solution of this utility model is as follows: a fruit juice sterilization device, including a sterilization kettle; a sterilization component for stirring sterilization is installed inside the sterilization kettle, and an auxiliary component for sterilizing fruit juice is installed outside the sterilization kettle. The sterilization component includes a heating rack, which is rotatably connected to the inside of the sterilization kettle. A stirring rod is symmetrically arranged at the center of the top of the heating rack, and an auxiliary rod is arranged outside the stirring rod.

[0006] Preferably, a stirring drum is installed at the middle position of the top of the stirring rod, a servo motor is installed at the middle position of the top of the sterilizer, the output end of the servo motor is connected to a rotating shaft, and a driven wheel is driven to the outside of the rotating shaft at the output end of the servo motor. A driving wheel is provided on the outside of the stirring drum, and the driving wheel and the driven wheel are driven to each other.

[0007] Preferably, a protective sleeve is provided above the outer side of the mixing drum, and the drive wheel is located inside the protective sleeve. A fixing frame is connected between the protective sleeve and the mixing rod.

[0008] Preferably, the sterilizer has an inlet pipe on its side wall and an outlet with a control valve at the middle of its bottom.

[0009] Preferably, the auxiliary components include connecting rods, which are located on the left and right sides of the sterilizer. A fixing block is installed on the opposite side of each connecting rod, and a support plate is installed on the opposite side of each fixing block.

[0010] Preferably, a support frame is installed at the bottom of the sterilizer, and connecting blocks are fixedly connected to both the left and right sides of the support frame, with the connecting blocks connected to the support plate.

[0011] Preferably, rubber pads are provided on both the front and rear sides of the top of the support frame, and the rubber pads are located below the sterilizer. Anti-slip pads are provided at the four corners of the bottom of the support frame, and a controller is installed on the left side wall of the left support plate.

[0012] The beneficial effects of this invention are as follows: by rotating the stirring rod and the auxiliary rod, the radial stirring force promotes the flow of the juice, breaks up local temperature stratification, and makes the heat evenly distributed. At the same time, the heating rack rotates at a constant speed in the sterilization pot to sterilize the juice at high temperature. This can avoid local overheating or incomplete sterilization of the juice, which not only shortens the time required for heating, but also reduces the loss of flavor substances in the juice, and preserves the original quality and taste of the juice to the greatest extent.

[0019] Please see Figures 1-5 This utility model provides an embodiment: a fruit juice sterilization device, including a sterilization vessel 1; a sterilization component for stirring sterilization is installed inside the sterilization vessel 1, and an auxiliary component for assisting fruit juice sterilization is installed on the outside of the sterilization vessel 1. The sterilization component includes a heating rack 401, which is rotatably connected to the inside of the sterilization vessel 1. A stirring rod 402 is symmetrically arranged at the center of the top of the heating rack 401, and an auxiliary rod 403 is arranged on the outside of the stirring rod 402. A liquid inlet pipe 2 is provided on the side wall of the sterilization vessel 1, and a discharge port 3 with a control valve is provided at the middle position of the bottom of the sterilization vessel 1.

[0020] Please see Figure 2 , Figure 5 In this embodiment, a stirring cylinder 404 is installed at the middle position of the top end of the stirring rod 402, and a servo motor 405 is installed at the middle position of the top end of the sterilizer 1. The output end of the servo motor 405 is connected to a rotating shaft, and a driven wheel is drivenly connected to the outer side of the rotating shaft at the output end of the servo motor 405. A driving wheel 406 is provided on the outer side of the stirring cylinder 404, and the driving wheel 406 and the driven wheel are drivenly connected. A protective sleeve 407 is provided above the outer side of the stirring cylinder 404, and the driving wheel 406 is located inside the protective sleeve 407. A fixing frame 408 is connected between the protective sleeve 407 and the stirring rod 402.

[0021] The stirring rod 402 has a stirring drum 404 fixed to its top. Therefore, when the stirring drum 404 rotates, the stirring rod 402 rotates synchronously to stir the juice in the sterilizer 1 in a circular motion, ensuring that the juice is evenly mixed during the sterilization process. The driving wheel 406 and the driven wheel are enclosed in the protective sleeve 407 to prevent juice or impurities from entering the transmission structure, thus preventing contamination and mechanical failure. The protective sleeve 407 is connected to the stirring rod 402 through the fixing bracket 408, which enhances the stability of the stirring drum 404 when it rotates, reduces vibration and deviation, thereby increasing the contact area between the juice and the high-temperature area, reducing dead zones, and allowing the juice temperature to rise quickly and evenly, shortening the sterilization time, while reducing the damage to nutrients caused by overheating.

[0022] Please see Figures 3-4 In this embodiment, the auxiliary components include connecting rods 501, which are disposed on the left and right sides of the sterilizer 1. A fixing block 502 is installed on the opposite side of each connecting rod 501, and a support plate 503 is installed on the opposite side of each fixing block 502. A support frame 504 is installed at the bottom of the sterilizer 1. Connecting blocks 505 are fixedly connected to both the left and right sides of the support frame 504, and the connecting blocks 505 are connected to the support plate 503. Rubber pads 506 are provided on the front and rear sides of the top of the support frame 504, and the rubber pads 506 are located below the sterilizer 1. Anti-slip pads 507 are provided at the four corners of the bottom of the support frame 504. A controller 508 is installed on the left side wall of the left support plate 503.

[0023] The rigid support frame is formed by the connecting rod 501 and the support plate 503. Combined with the fixed structure of the support frame 504, it ensures that the equipment does not shake during the sterilization process and is suitable for long-term stable operation. The rubber pad 506 reduces vibration and impact and protects the internal structure of the sterilizer 1. The anti-slip pad 507 enhances the grip of the equipment on the ground and avoids safety hazards caused by operation or slippery ground.

[0024] During operation, the inlet pipe 2 is connected to the external pipe, and the juice to be sterilized is injected into the sterilizer 1 through the pipe. After the juice enters the sterilizer 1, the heating rack 401 is turned on to evenly heat the juice in the sterilizer 1 until the temperature reaches the required sterilization range. At the same time, the servo motor 405 is started, and its output shaft drives the driven wheel to rotate through the rotating shaft. The driven wheel and the drive wheel 406 are connected by a transmission, thereby driving the stirring drum 404 to rotate. When the stirring drum 404 rotates, the protective sleeve 407 and the stirring rod 402 rotate synchronously through the fixed frame 408. The auxiliary rod 403 rotates with the stirring rod 402, stirring the juice from multiple angles. Stirring ensures even heating and avoids localized overheating or incomplete sterilization. The connecting rods 501 on both sides of the sterilizer 1 are connected to the support plate 503 via the fixing block 502 to form a stable support frame. The support plate 503 is connected to the support frame 504 via the connecting block 505, so that the sterilizer 1 is fixed above the support frame 504, ensuring the stability of the equipment during sterilization and preventing shaking or displacement. The rubber pad 506 at the top of the support frame 504 is located below the sterilizer 1, which can buffer the weight of the sterilizer 1 and reduce vibration transmission. The anti-slip pads 507 at the four corners of the bottom increase the friction between the equipment and the ground, prevent the device from sliding during operation, and improve safety.
