Description

Technical Field

[0001] This utility model belongs to the field of food sterilization technology, specifically relating to an ultra-high temperature instantaneous sterilization device with feedback function. Background Technology

[0002] The current food industry uses ultra-high temperature instantaneous sterilization (UHT), which involves heating materials to 135-150℃ and holding for 2-8 seconds, followed by rapid cooling to maintain the original quality of the food. When UHT enters the production stage, the sterilized product flows through pipelines into an aseptic tank. If multiple aseptic tanks are used, they are typically connected and switched between aseptic tanks and UHT by controlling the opening and closing of valves V101 and V164. When product enters the aseptic tank, the corresponding V101 valve at the bottom of the tank opens, while the V164 valve between the last aseptic tank and the UHT closes. During UHT production, if the associated V164 valve malfunctions, such as a manual shutdown of the gas supply or a gas leak, the UHT may not receive the relevant information and continue supplying material to the aseptic tank. However, because V164 is open, some material enters the aseptic tank while some is discharged through the circulation pipeline, resulting in production losses. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-high temperature instantaneous sterilization device with feedback function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ultra-high temperature instantaneous sterilization device with feedback function, comprising a UHT system, at least two sterile tanks, a material conveying pipeline connecting the sterile tanks and the UHT system, a V101 valve disposed at the bottom of the sterile tanks, and a V164 valve disposed between the last sterile tank and the UHT system;

[0005] The V164 valve is equipped with a feedback head for real-time detection of the V164 valve's on / off status or pneumatic pressure signal.

[0006] The UHT system integrates a feedback control module, which is electrically connected to the feedback head. When the feedback head detects abnormal operation or malfunction of the V164 valve, the feedback control module immediately controls the UHT system to stop the material production step and switch to the water circulation step, discharging the remaining material through the connected external circulation pipeline.

[0007] Preferably, the feedback head is a valve position sensor or a pneumatic pressure sensor, used to monitor the actual position of the valve core of the V164 valve or the air pressure value of the pneumatic actuator; when the valve core is not closed to the preset position or the air pressure value is lower than 0.4MPa, the feedback head generates a fault signal and transmits it to the feedback control module. The valve position sensor can accurately monitor the actual position of the valve core. If the valve core fails to close to the preset position according to production requirements, it means that material may leak or divert, thereby affecting product quality and production efficiency.

[0008] Preferably, the pneumatic actuator of the V164 valve is connected to an external air source device via an air pipe. The air pipe is equipped with an air pressure monitoring unit, which is connected to the feedback control module for detecting air pipe leakage or air source interruption. If the air pipe leaks, the pneumatic actuator will have insufficient air pressure, causing the V164 valve to fail to operate accurately. An interruption of the air source will directly cause the V164 valve to lose power and become unable to work.

[0009] Preferably, the feedback control module is connected to an audible and visual alarm. When the V164 valve malfunctions, the audible and visual alarm is triggered synchronously and displays the fault code. The audible and visual alarm is set to immediately emit a loud alarm sound and flash a conspicuous light when the V164 valve malfunctions.

[0010] Preferably, the feedback control module includes a data storage unit for recording the failure time and type of the V164 valve and the operation record of switching water circulation in the UHT system. Recording the failure time of the V164 valve can help production managers to count the frequency of equipment failures so as to reasonably arrange equipment maintenance plans.

[0011] Preferably, the UHT system and the feedback control module are connected via an industrial communication protocol, supporting real-time monitoring of the V164 valve status and control of water circulation steps via remote terminals. Production managers can obtain the V164 valve status information in real time via remote terminals, understanding the equipment operation without being physically present at the production site. In the event of a V164 valve malfunction, the UHT system can be quickly switched to the water circulation step via remote terminal control, promptly discharging remaining materials and preventing material waste and equipment damage.

[0012] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This ultra-high temperature instantaneous sterilization device with feedback function...

[0013] This invention adds a feedback head to the V164 valve associated with the UHT system and adds feedback information to the UHT system. When the V164 fails, the UHT system receives the feedback information and takes corresponding actions in a timely manner, such as switching to water circulation, thereby reducing production losses.

[0014] This utility model, by utilizing audible and visual alarms, data recording, and remote monitoring, enables rapid fault warning, provides a basis for equipment maintenance, and allows for remote control of equipment in emergencies, thereby comprehensively improving the efficiency of equipment maintenance and management.

[0015] Figure 1 This is a block diagram of the ultra-high temperature instantaneous sterilization device of this utility model. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 This utility model provides a technical solution: an ultra-high temperature instantaneous sterilization device with feedback function, including a UHT system, at least two aseptic tanks, a material conveying pipeline connecting the aseptic tanks and the UHT system, a V101 valve located at the bottom of the aseptic tank, and a V164 valve located between the last aseptic tank and the UHT system. In this system, the UHT system undertakes the core task of ultra-high temperature instantaneous sterilization of materials, heating the materials to 135-150℃ and holding for 2-8 seconds before rapid cooling to ensure that the original quality of the food is preserved. The aseptic tanks are used to store products sterilized by the UHT system. Multiple aseptic tanks, in conjunction with the V101 valve, enable the orderly storage and switching of different batches of products.

[0018] The V164 valve is equipped with a feedback head for real-time detection of its on / off status or pneumatic pressure signal. This head can be either a valve position sensor or a pneumatic pressure sensor. The valve position sensor accurately monitors the actual position of the V164 valve spool. If the spool fails to close accurately to the preset position as required by production standards, it indicates a potential leak or diversion in the material conveying path, which would severely impact product quality and production efficiency. In this case, the feedback head will immediately generate a fault signal. The pneumatic pressure sensor focuses on monitoring the air pressure of the V164 valve's pneumatic actuator. When the air pressure is below 0.4 MPa, it indicates a pneumatic system malfunction, failing to provide sufficient power for the normal operation of the V164 valve. This will also trigger the feedback head to generate a fault signal, which will be transmitted to the feedback control module.

[0019] The UHT system integrates a feedback control module, which is electrically connected to the feedback head. When the feedback head detects abnormal operation or malfunction of the V164 valve, the feedback control module immediately controls the UHT system to stop the material production step and switch to the water circulation step. Remaining material is discharged through a connected external circulation pipeline. The integrated feedback control module of the UHT system is the "intelligent brain" of the entire device. It is electrically connected to the feedback head and receives various signals from it. When the feedback control module receives a signal of abnormal operation or malfunction of the V164 valve, it can immediately play a crucial control role, quickly controlling the UHT system to stop the material production step, avoiding continuous material waste due to V164 valve malfunction. Simultaneously, the feedback control module automatically switches to the water circulation step, discharging remaining material from the equipment through the connected external circulation pipeline, effectively protecting the equipment and preventing damage from material residue.

[0020] The feedback head is a valve position sensor or a pneumatic pressure sensor, used to monitor the actual position of the valve core of the V164 valve or the air pressure value of the pneumatic actuator; when the valve core is not closed to the preset position or the air pressure value is lower than 0.4MPa, the feedback head generates a fault signal and transmits it to the feedback control module.

[0021] The pneumatic actuator of the V164 valve is connected to an external air source device via an air pipe. An air pressure monitoring unit is installed on the air pipe, and this unit is signal-connected to the feedback control module. To ensure the stability of the air supply, a air pressure monitoring unit is installed on the air pipe. This unit is signal-connected to the feedback control module and constantly monitors changes in air pressure within the air pipe. If the air pipe leaks, insufficient air pressure will cause the pneumatic actuator to malfunction, preventing the V164 valve from operating accurately. An interruption of the air supply will directly cause the V164 valve to lose power and cease normal operation. Once the air pressure monitoring unit detects an abnormal drop or zero air pressure, it will quickly send a signal to the feedback control module to promptly identify and address air pipe leaks or air supply interruptions.

[0022] The feedback control module is connected to an audible and visual alarm. When the V164 valve malfunctions, the audible and visual alarm is triggered simultaneously and displays the fault code. When the V164 valve malfunctions, the audible and visual alarm will be triggered simultaneously with a loud alarm sound and a conspicuous flashing light to attract the operator's attention immediately. At the same time, the specific fault code is displayed, which makes it convenient for the operator to quickly identify the fault type and carry out targeted maintenance work in a timely manner, greatly shortening the equipment downtime and ensuring the continuity of the production process.

[0023] The feedback control module includes a data storage unit for recording the failure time and type of the V164 valve, as well as the operation records of the UHT system switching water circulation. This data is extremely valuable to production managers. By analyzing the failure time, the frequency of equipment failures can be statistically analyzed, allowing for the rational planning of equipment maintenance. Based on the failure type, technicians can thoroughly analyze the causes of failures, summarize lessons learned, and provide strong support for optimizing and upgrading equipment performance.

[0024] The UHT system and feedback control module are connected via an industrial communication protocol, supporting real-time monitoring of the V164 valve status and control of water circulation steps via remote terminals. This connection method allows production managers to obtain V164 valve operating status information remotely without being physically present on the production site. In the event of a V164 valve malfunction, the UHT system can be quickly switched to the water circulation step via remote terminal control, promptly discharging remaining materials, avoiding material waste and equipment damage, truly achieving intelligent remote control of equipment, and comprehensively improving production management efficiency.

[0025] Specifically, during operation, a feedback head, either a valve position sensor or a pneumatic pressure sensor, is installed on the V164 valve to monitor its operating status in real time. The valve position sensor accurately monitors the actual position of the valve core; if the valve core fails to reach the preset closed position, it indicates potential material leakage or diversion. The pneumatic pressure sensor monitors the air pressure value of the pneumatic actuator; when the air pressure drops below 0.4 MPa, it indicates a pneumatic system malfunction, and the V164 valve cannot function properly. Simultaneously, an air pressure monitoring unit on the air pipe monitors changes in air pressure within the pipe in real time. If the air pressure drops abnormally or reaches zero, it can promptly detect air leaks or air supply interruptions. This monitoring data is fed back to the feedback control module in real time, providing a basis for judging the device's operating status.

[0026] When the feedback control module receives a fault signal from the feedback head or air pressure monitoring unit, it immediately takes countermeasures. Firstly, it quickly stops the material production step of the UHT system to avoid continuous material waste and production losses due to the V164 valve malfunction. Secondly, it switches to the water circulation step, discharging remaining material through an external circulation pipeline to protect the equipment from potential damage caused by material residue. Simultaneously, the audible and visual alarm connected to the feedback control module is triggered, alerting operators with a loud alarm sound and a bright flashing light, and displaying the fault code to facilitate quick identification and repair. Furthermore, the data storage unit within the feedback control module records the V164 valve malfunction time and type, as well as the UHT system's water circulation switching operation record, for subsequent equipment operation status analysis and maintenance plan development. Production management personnel can also monitor the V164 valve status in real time via an industrial communication protocol on a remote terminal, and promptly control the UHT system to switch to water circulation when a fault occurs, comprehensively ensuring production safety and stability.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
