Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature sterilization, and in particular to a tube sterilizer. Background Technology

[0002] Tubular sterilizers are indirect heating sterilization devices, representing one application of shell-and-tube heat exchangers in the food industry. Horizontal tubular sterilizers are commonly used in the food industry. Their working principle involves pumping materials into stainless steel heating tubes using a high-pressure pump. Steam is introduced into the flow chamber, heating the materials flowing within the tubes. After the materials circulate several times within the tubes, they reach the required sterilization temperature and hold time before being discharged as a finished product. For example, the prior art publication CN217829169U discloses a tubular sterilizer capable of rapid heat exchange, comprising a base plate. A sterilizer body is mounted on one end of the upper surface of the base plate, and a controller is mounted on the front surface of the sterilizer body. A first and second tube are connected to the side wall of the sterilizer body. A material hopper is located at the other end of the upper surface of the base plate. A discharge pump is installed at the lower end of the outer wall of the material hopper via a pipe. A discharge pipe connects the discharge end of the discharge pump to the first tube. Both the first and second tubes include straight pipe sections and U-shaped pipe sections. However, when heated at high temperatures, some materials contain substances that solidify upon heating. After solidification, some of these substances may adhere to the pipe wall, which over time can affect the flow rate in the pipe and even cause blockage. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a tube sterilizer that ensures contact with high-temperature steam, improves sterilization effect, and ensures that substances that solidify when heated inside the sterilization tube do not adhere to the inner wall of the tube cavity.

[0004] This utility model discloses a tube sterilizer, comprising a feeding cylinder, a feeding pipe, a sterilization component, a rotating assembly, a discharging component, and a flow assembly. The feeding pipe is connected to the bottom of the feeding cylinder, the sterilization component is installed at the top of the feeding cylinder, the flow assembly is installed inside the sterilization component via the rotating assembly, and the discharging component is installed at the top of the sterilization component. The output end of the flow assembly is connected to the interior of the discharging component. Material is fed into the feeding cylinder through the feeding pipe and into the flow assembly. High-temperature steam enters the sterilization component. The rotating assembly drives the flow assembly to rotate, ensuring contact with the high-temperature steam and improving the sterilization effect. The rotation generates a certain centrifugal force, which changes accordingly with the change in the rotation direction of the flow assembly, thereby ensuring that the material solidified by heat inside the sterilization tube does not adhere to the inner wall of the tube cavity.

[0005] Preferably, the sterilization component includes a sterilization cylinder, a steam injection port, an exhaust port, and a temperature sensor. The sterilization cylinder is installed at the top of the feed cylinder. The lower part of the outer wall of the sterilization cylinder is connected to the steam injection port, and the upper part of the outer wall of the sterilization cylinder is connected to the exhaust port. A temperature sensor is installed on the outer wall of the middle part of the sterilization cylinder. High-temperature steam is introduced into the sterilization cylinder through the steam injection port to sterilize the material at high temperature. The heated high-temperature steam is discharged through the exhaust port. The temperature sensor is used to detect the temperature inside the sterilization cylinder to ensure that the temperature is within the required range.

[0006] Preferably, the discharge component includes a discharge cylinder, multiple support rods, and a discharge pipe. Multiple support rods are axially installed on the outer wall of the discharge cylinder, and the bottom of the support rods is connected to the upper outer wall of the sterilization cylinder. The discharge pipe is connected to the top of the discharge cylinder. The material after high-temperature sterilization enters the discharge cylinder and can be discharged through the discharge pipe for subsequent processing.

[0007] Preferably, the flow components include a filter screen, multiple flow tubes, and a slow-flow filter plate. The filter screen is installed inside the feed cylinder, the multiple flow tubes are evenly located inside the sterilization cylinder, and the slow-flow filter plate is installed inside the discharge cylinder. After the material enters the feed cylinder, it is filtered by the filter screen. The material flows in the flow tubes, and the heat exchange between the material and the high-pressure steam in the flow tubes is rapid, resulting in high-temperature sterilization of the material. The slow-flow filter plate slows down the flow, ensuring the sterilization effect on the material.

[0008] Preferably, the rotating component includes a rotating disk, an upper rotating seat, a first sealing ring, a second sealing ring, a gear ring, a fixed plate, a drive motor, and a drive gear. A sealing groove is formed on the lower inner wall of the sterilization cylinder. A second sealing ring is installed on the outer wall of the rotating disk, rotating within the sealing groove. Second sealing grooves are formed at the bottom of the discharge cylinder and the top of the sterilization cylinder. First sealing rings are installed at both the upper and lower ends of the upper rotating seat, rotating within the second sealing groove. A gear ring is installed on the lower outer wall of the upper rotating seat. The fixed plate is installed on the outer wall of the sterilization cylinder. The drive motor is installed at the bottom of the fixed plate, and the output end of the drive motor... Equipped with a drive gear that meshes with a gear ring, the bottom input end of the flow tubes is mounted on a rotating disc and communicates with the inside of the feed cylinder. The output end of the flow tubes is mounted on an upper rotating seat and communicates with the inside of the discharge cylinder. When the drive motor is started, it drives the drive gear to rotate, which in turn drives the upper rotating seat to rotate via the gear ring. The upper rotating seat drives multiple flow tubes to rotate inside the sterilization cylinder, ensuring uniform contact with the steam. At the same time, the rotation will generate a certain centrifugal force, which will change accordingly as the direction of rotation of the flow components changes. This ensures that the material that solidifies when heated inside the sterilization tube will not adhere to the inner wall of the tube cavity.

[0009] Preferably, the device also includes a diversion pipe, a sampling box, a sampling tube, a reflux pipe, and a valve. The inlet end of the diversion pipe is connected to the inside of the discharge cylinder, and a valve is installed on the diversion pipe. The outlet end of the diversion pipe is equipped with a sampling box, and a sampling tube is installed on the sampling box. The inlet end of the reflux pipe is connected to the inside of the discharge cylinder, and the outlet end of the reflux pipe is connected to the inside of the feed cylinder. A valve is installed on the reflux pipe. By opening the valve on the diversion pipe, the sterilized material is input into the sampling box. The material is then taken out for testing through the sampling tube. If the sterilization effect does not meet the requirements, the valve is opened, and the material is introduced into the feed cylinder through the reflux pipe for repeated sterilization to ensure food safety.

[0010] Preferably, it also includes a heating rod, which is installed in the middle of the slow-flow filter plate, rotates through the middle of the upper rotating seat, and is located in the middle of the sterilization cylinder; the heating rod can further heat the inside of the sterilization cylinder to improve the sterilization quality.

[0011] Preferably, it also includes a base, which is installed at the bottom of the feed cylinder and the feed pipe is installed on the base; the base supports the bottom of the equipment to ensure the stability of the equipment during operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is fed into the feed cylinder through the feed pipe, the material is fed into the flow component, the high temperature steam enters the sterilization component, the rotating component can drive the flow component to rotate, ensuring contact with the high temperature steam and improving the sterilization effect. The rotation will generate a certain centrifugal force, and the centrifugal force will change accordingly with the change of the rotation direction of the flow component, thereby ensuring that the substance solidified by heat in the sterilization tube will not adhere to the inner wall of the tube cavity.
