Description

Technical Field

[0001] This utility model relates to the field of tunnel microwave sterilization technology, specifically a sterilization device for oat beverage processing. Background Technology

[0002] With the rapid development of the food industry, plant-based protein drinks are gaining popularity among consumers due to their health, nutrition, and environmental benefits. Oat drinks, as a typical plant-based beverage, have extremely high hygiene and safety requirements during production, especially in the sterilization process after filling and sealing. It is essential to ensure that the product is processed under sterile or highly clean conditions to prevent microbial contamination and guarantee product quality and shelf life.

[0003] Currently, commonly used sterilization methods include high-temperature steam sterilization, pasteurization, and microwave sterilization technology, which has been widely adopted in recent years. Among these, microwave sterilization has advantages such as uniform heating, high sterilization efficiency, low energy consumption, and simple operation, and is gradually becoming an important sterilization method in the food and beverage industry. However, in practical applications, especially in continuous production lines for oat beverages, there are still some technical problems that urgently need to be solved.

[0004] Firstly, at the outlet of the microwave sterilization equipment, trays loaded with beverage bottles are typically conveyed out via a conveyor belt. Due to the high speed of the conveyor belt, the trays are prone to significant inertial impact when they reach the end. Without an effective cushioning device, the trays will collide violently with the discharge structure, causing damage or even explosion of the internal packaging bottles, resulting in material waste and equipment downtime for cleaning, affecting production efficiency and safety.

[0005] Secondly, the microwave sterilization process significantly raises the temperature of the metal pallet rims, especially in continuous operation environments. The surface temperature of the pallet rims often exceeds the safe contact range for humans, posing a significant safety hazard as employees are highly susceptible to burns during handling. Although some equipment incorporates natural cooling zones or manual airflow at the discharge port, the cooling efficiency is low and insufficient to meet the demands of efficient continuous production. Often, it's necessary to wait for the material to cool down before handling, reducing the overall production line efficiency. Therefore, a sterilization device for oat beverage processing is needed to address these issues. Utility Model Content

[0006] The purpose of this invention is to provide a sterilization device for oat beverage processing, which has the advantages of buffering and shock absorption and rapid cooling, and solves the problems of packaging bottle damage caused by pallet impact and excessive temperature of the protective edge affecting handling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for oat beverage processing, comprising a tunnel microwave sterilizer and a tray, wherein the tunnel microwave sterilizer is provided with a buffer mechanism and a cooling mechanism;

[0008] The tunnel microwave sterilization machine includes a housing, a microwave generator, a microwave shield, and a conveyor belt. The microwave generator and microwave shield are fixedly installed inside the housing. The conveyor belt is installed on the housing. The buffer mechanism is installed on the housing. The buffer mechanism includes a buffer plate, a spring, and a vertical plate. The buffer plate and the vertical plate are elastically slidably connected by the spring. The buffer mechanism is located at the end of the conveyor belt. The cooling mechanism includes a water tank, a submersible pump, a guide plate, and an atomizing nozzle.

[0009] In a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, a piston rod is provided on the side end face of the buffer plate, and a sliding hole that cooperates with the piston rod is provided on the side end face of the upright plate, with the spring installed in the sliding hole.

[0010] As a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, the side end face of the sliding hole is provided with an exhaust hole.

[0011] As a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, the front end face of the buffer plate is provided with a rubber pad.

[0012] As a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, the upper surface of the guide plate is provided with an airflow channel corresponding to the position of the atomizing nozzle, the tray includes a holding frame and a guard edge, and the guide plate is located at the lower end of the guard edge.

[0013] As a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, a motor is provided in the airflow channel, and axial flow fan blades are provided on the output shaft of the motor.

[0014] As a preferred embodiment of the sterilization equipment for oat beverage processing according to this utility model, the upper end face of the guide plate is provided with a reflux groove, and the bottom of the reflux groove is provided with a reflux hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through a buffer mechanism installed at the end of the conveyor belt, produces a multi-level synergistic buffering and energy absorption effect, solving the key problem of damage to internal beverage packaging bottles caused by high-speed impact of the tray after sterilization. When the microwave-sterilized tray impacts the buffer plate with the conveyor belt, the buffer plate drives the piston rod to compress the spring in the sliding hole to store energy. The exhaust hole design on the side wall of the sliding hole requires air to be slowly drawn in or expelled when the piston rod moves, generating an air damping effect, which significantly slows down the speed of spring compression and rebound, avoiding rigid collisions and instantaneous rebound impacts. At the same time, the rubber pad covering the front end of the buffer plate provides a soft initial contact surface, further absorbing impact energy and preventing scratches on the tray surface. This structural combination effectively converts the tray's powerful kinetic energy into spring potential energy and air friction heat energy for dissipation, greatly reducing the instantaneous impact force transmitted to the tray and internal packaging bottles, thereby significantly reducing the risk of "bottle explosion" and ensuring product integrity and production safety.

[0017] 2. This utility model, through the synergistic action of the cooling mechanism, airflow channel on the guide plate, waterproof motor, axial fan blades, return groove, and return hole, achieves rapid and directional forced cooling of the pallet edge. This solves the problem of excessively high temperatures on the metal pallet edge after microwave sterilization, leading to employee burns and disruptions to production continuity due to the inability to handle the pallet promptly. The submersible pump pumps water from the storage tank to the atomizing nozzle to form water mist. Simultaneously, the waterproof motor in the airflow channel drives the axial fan blades to generate a strong upward airflow. This airflow precisely blows onto the lower surface of the pallet edge, carrying and accelerating the evaporation of the water mist sprayed from the atomizing nozzle. The water mist absorbs a large amount of heat as it evaporates on the edge surface. The forced airflow not only accelerates the evaporation and heat dissipation process but also directly removes the heat, achieving efficient and active cooling of the edge. This ensures that employees can safely remove the pallet by hand immediately after the sterilization process for subsequent operations, eliminating the risk of burns and preventing production line stagnation caused by waiting for the pallet to cool naturally. This significantly improves operational safety and overall production efficiency. Attached Figure Description

Detailed Implementation

[0027] Please see Figures 1-8 A sterilization device for processing oat beverages includes a tunnel microwave sterilizer 1 and a tray 4. The tunnel microwave sterilizer 1 is equipped with a buffer mechanism 2 and a cooling mechanism 3.

[0028] The tunnel microwave sterilization machine 1 includes a housing 101, a microwave generator 102, a microwave shield 103, and a conveyor belt 104. The microwave generator 102 and the microwave shield 103 are fixedly installed inside the housing 101. The conveyor belt 104 is installed on the housing 101. The buffer mechanism 2 is installed on the housing 101. The buffer mechanism 2 includes a buffer plate 201, a spring 204, and a vertical plate 202. The buffer plate 201 and the vertical plate 202 are elastically slidably connected by the spring 204. The buffer mechanism 2 is located at the end of the conveyor belt 104. The cooling mechanism 3 includes a water tank 301, a submersible pump 302, a guide plate 305, and an atomizing nozzle 304. The submersible pump 302 is connected to the water supply pipe 303 through the atomizing nozzle 304.

[0029] Furthermore, a piston rod 205 is provided on the side end face of the buffer plate 201, and a sliding hole 206 that cooperates with the piston rod 205 is provided on the side end face of the upright plate 202, with the spring 204 installed in the sliding hole 206.

[0030] The buffer plate 201 and the upright plate 202 are elastically slidably connected by the piston rod 205, the sliding hole 206 and the spring 204, so that when the tray 4 is sterilized, it impacts the buffer plate 201 to buffer and unload the force, reducing the impact on the internal packaging bottles and reducing the probability of bottle explosion.

[0031] Furthermore, an exhaust hole 207 is provided on the side end face of the sliding hole 206.

[0032] By providing an exhaust port 207 in the sliding hole 206, the piston rod 205 can slowly draw in and exhaust air through the exhaust port 207 when sliding in the sliding hole 206, thereby achieving damping efficiency, reducing the rebound rate of the spring 204, and further reducing the impact on the tray 4.

[0033] Furthermore, a rubber pad 203 is provided on the front end face of the buffer plate 201.

[0034] The rubber pad 203 enhances the softness of the buffer plate 201, reducing the impact intensity on the tray 4 and preventing scratches and damage to the tray 4 during the lifting process.

[0035] Furthermore, the upper surface of the guide plate 305 is provided with an airflow channel 306 corresponding to the position of the atomizing nozzle 304, and the tray 4 includes a holding frame 402 and a guard edge 401, with the guide plate 305 located at the lower end of the guard edge 401.

[0036] The airflow from the atomizing nozzle 304 is blown upwards through the airflow channel 306 toward the pallet 4 guardrail 401 to cool it down and prevent the pallet 4 guardrail 401 from getting too hot, which would make it inconvenient for employees to handle.

[0037] Furthermore, a motor 307 is installed inside the airflow channel 306, and an axial flow fan blade 308 is installed on the output shaft of the motor 307.

[0038] The motor 307 drives the axial fan blades 308 to generate an upward airflow, which blows the water vapor sprayed from the atomizing nozzle 304 toward the lower end face of the guard 401. The airflow accelerates the evaporation of water vapor, improves the heat dissipation efficiency of the guard 401, and allows employees to remove the tray 4 immediately. The motor 307 is a waterproof motor 307.

[0039] Furthermore, a return groove 309 is provided on the upper end face of the guide plate 305, and a return hole 310 is provided at the bottom of the return groove 309.

[0040] Water droplets from the surface of the guard 401 fall into the return groove 309 and are eventually discharged through the return hole 310. The return hole 310 can be guided to the factory drainage ditch through a conduit.

[0041] When using this sterilization equipment, first place the tray 4 containing the oat beverage packaging bottles at the starting end of the conveyor belt 104 of the tunnel microwave sterilizer 1, start the equipment, and the microwave generator 102 and conveyor belt 104 will start working. The microwave generator 102 generates microwaves to sterilize the tray 4 and the beverage inside the conveyor belt 104 within the casing 101. When the tray 4 moves to the end of the conveyor belt 104, it will collide with the buffer plate 201 located at the end of the conveyor belt 104. Since the buffer plate 201 and the upright plate 202 are elastically connected by the piston rod 205, the sliding hole 206 and the spring 204, the spring 204 is compressed to buffer and relieve the force. At the same time, the exhaust hole 207 on the side end face of the sliding hole 206 achieves a damping effect, reducing the rebound of the spring 204. The speed further reduces the impact on the pallet 4. The rubber pad 203 on the front end of the buffer plate 201 can also reduce the impact intensity on the pallet 4 and prevent scratch damage. After sterilization, the cooling mechanism 3 starts to work. The submersible pump 302 draws water from the water storage tank 301 and delivers it to the atomizing nozzle 304. The water vapor sprayed from the atomizing nozzle 304 passes through the airflow channel 306 on the upper end of the guide plate 305. At the same time, the motor 307 drives the axial flow fan blade 308 to generate an upward airflow, blowing the water vapor towards the lower end of the pallet 4 guard edge 401, accelerating the evaporation of water vapor, cooling the pallet 4 guard edge 401, and facilitating employee handling. The water droplets on the surface of the guard edge 401 will drip into the return groove 309 on the upper end of the guide plate 305 and finally be discharged into the factory drainage ditch through the return hole 310.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
