Description

Technical Field

[0001] This utility model relates to the field of food sterilization technology, and in particular to a microwave sterilization device for food. Background Technology

[0002] Microwave sterilization technology uses high-frequency electromagnetic waves to cause polar molecules (such as water molecules) in food to vibrate rapidly and generate heat, while simultaneously disrupting the cell membrane potential of microorganisms. It can achieve efficient sterilization in a low-temperature range of 70-100℃. Compared with traditional high-temperature sterilization, it can increase the vitamin retention rate of food by 30% to 50%, and shorten the sterilization time to 1 / 3 to 1 / 5 of the traditional method, greatly improving production efficiency. It is widely used in the processing of various foods such as pre-cooked dishes, cleaned vegetables, nuts, and seasonings.

[0003] As shown in the reference case "A Sterilization and Drying Device for a Microwave Food Dryer" (publication number CN219511199U), a sterilization and drying device for a microwave food dryer includes a shell. A feeding hopper is fixedly connected to one side of the shell. A horizontal plate is fixedly connected to the upper part of the inner wall of the shell. An ultraviolet germicidal lamp is fixedly connected to the bottom of the horizontal plate. A magnetron is fixedly connected to the bottom of the horizontal plate. A first rotating roller is rotatably connected to the inner wall of the shell. A shovel plate is fixedly connected to the outer wall of the first rotating roller. A conveyor belt is attached to the bottom of the shovel plate. This utility model relates to the field of microwave drying technology. This sterilization and drying device for a microwave food dryer, through the cooperation of the first rotating roller, shovel plate, magnetron, ultraviolet germicidal lamp, and conveyor belt, can perform drying and sterilization treatment during material transportation. Furthermore, the material can be turned over during transportation, ensuring that the material is heated from multiple angles, improving the drying and sterilization quality, reducing working time, and increasing work efficiency.

[0004] However, when the above-mentioned device is in use, although the shovel can turn the material when it rotates, the shovel can only act on the upper surface and sides of the material when it turns it, and it is difficult to completely peel the material off the surface of the conveyor belt. The bottom of the shovel and the contact surface with the conveyor belt will still form a sterilization blind zone because the microwave cannot penetrate the conveyor belt, so there is room for improvement. Utility Model Content

[0005] Therefore, it is necessary to provide a food microwave sterilization device to address the above problems.

[0006] A microwave sterilization device for food includes: a base, two drive rollers symmetrically arranged inside the base, a corresponding conveyor belt between the two drive rollers, a motor mounted on one side of the base, and the output shaft of the motor fixedly connected to one end of one of the drive rollers; a uniform sterilization mechanism disposed on the base, the uniform sterilization mechanism including a drive pulley fixedly connected to the surface of one of the drive rollers, mounting blocks symmetrically arranged inside the base, a rotating roller rotatably connected between the mounting blocks, a plurality of actuating plates evenly distributed on the surface of the rotating roller, a driven pulley fixedly connected to the surface of the rotating roller, and the driven pulley and the drive pulley being connected by a drive belt.

[0007] In one embodiment, the rotating rollers are symmetrically arranged in the base, and each of the two rotating rollers is provided with a driven pulley, which is also connected to each other by a transmission belt.

[0008] In one embodiment, the length of the actuating plate is greater than the width of the conveyor belt, one end of the actuating plate is provided with an arc-shaped edge, and the diameter of the driving pulley is greater than the diameter of the driven pulley.

[0009] In one embodiment, a protective cover is installed on the base, and a microwave generator and an ultraviolet germicidal lamp are fixedly connected inside the protective cover. Baffles are slidably connected to both sides of the protective cover.

[0010] In one embodiment, the base is provided with an adjustment mechanism, the adjustment mechanism including a groove formed on the surface of the base, the mounting block being slidably connected in the groove, an electric push rod being fixedly connected in the groove, and the telescopic end of the electric push rod being fixedly connected to the bottom of the mounting block.

[0011] In one embodiment, a limiting groove is formed on the surface of the base, a limiting block is slidably connected in the limiting groove, a tensioning pulley is rotatably connected to one side of the limiting block, and a spring is fixedly connected between the bottom of the limiting block and the limiting groove.

[0012] In one embodiment, the outer circumferential surface of the tensioning pulley is provided with an annular groove, the width of which is adapted to the width of the transmission belt, and the inner sidewall of the annular groove is provided with anti-slip texture.

[0013] In one embodiment, the end of the actuating plate away from the rotating roller is detachably connected to a wear-resistant head, and the end face of the wear-resistant head that contacts the conveyor belt is an arc-shaped surface.

[0014] This utility model has the following beneficial effects:

[0015] 1. The above-mentioned microwave food sterilization device achieves food flipping by indirectly transmitting vibration through a slapping plate hitting the bottom of the conveyor belt. It does not require direct contact with the food, reducing the breakage rate of soft foods and improving the appearance and commercial value of the food. During the vibration flipping process, the food bounces briefly due to the slapping of the conveyor belt, detaching from the contact surface with the conveyor belt, so that the microwave can irradiate the upper and lower surfaces of the food from all directions, avoiding sterilization blind spots.

[0016] 2. The mounting block is raised and lowered by an electric push rod, which can flexibly adjust the distance between the rotating roller and the actuating plate and the conveyor belt, adapting to various types of food with different thicknesses. Unlike existing devices, it does not require frequent replacement of the flipping parts or machine shutdown for debugging. The annular groove and anti-slip texture of the tensioning pulley work together to automatically keep the transmission belt tensioned when the height of the rotating roller is adjusted, avoiding the flipping mechanism from stopping due to belt slippage, making it easy to use.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figure 1 - Figure 5 This invention describes a microwave sterilization device for food.

[0026] In one embodiment, a microwave sterilization device for food includes: a base 100, two drive rollers 300 symmetrically arranged inside the base 100, a corresponding conveyor belt 400 between the two drive rollers 300, a motor 200 mounted on one side of the base 100, and the output shaft end of the motor 200 fixedly connected to one end of one of the drive rollers 300; a uniform sterilization mechanism 600 disposed on the base 100, the uniform sterilization mechanism 600 including a drive pulley 610 fixedly connected to the surface of one drive roller 300, mounting blocks 620 symmetrically arranged inside the base 100, rotating rollers rotatably connected between the mounting blocks 620, a plurality of actuating plates 650 evenly distributed on the surface of the rotating rollers, a driven pulley 630 fixedly connected to the surface of the rotating rollers, and the driven pulley 630 and the drive pulley 610 being connected by a drive belt 640.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, rotating rollers are symmetrically arranged within the base 100. Each of the two rotating rollers has a driven pulley 630 on its surface, and the two driven pulleys 630 are connected by a transmission belt 640. The length of the actuating plate 650 is greater than the width of the conveyor belt 400, and one end of the actuating plate 650 has an arc-shaped edge. The diameter of the driving pulley 610 is greater than the diameter of the driven pulley 630. A protective cover 500 is installed on the base 100. A microwave generator and an ultraviolet germicidal lamp are fixedly connected inside the protective cover 500, and baffles are slidably connected to both sides of the protective cover 500. A wear-resistant head is detachably connected to the end of the actuating plate 650 away from the rotating rollers, and the end face of the wear-resistant head that contacts the conveyor belt 400 is an arc-shaped surface.

[0028] In this embodiment, the base 100 provides support for the entire device. After the motor 200 starts, it drives the transmission roller 300 connected to it to rotate. Through the linkage of the conveyor belt 400, it drives another transmission roller 300 to rotate synchronously, realizing the continuous conveying of food on the conveyor belt 400. The protective cover 500 forms a closed sterilization space above the conveyor belt 400. The microwave generator inside releases microwaves and the ultraviolet germicidal lamp emits ultraviolet rays, which work together to improve the sterilization effect. The baffles on both sides can be adjusted to open and close according to the width of the food to prevent microwave leakage.

[0029] As the drive roller 300 rotates, the drive pulley 610 rotates synchronously, driving the driven pulley 630 and the rotating roller to rotate via the drive belt 640. The agitator plate 650 on the surface of the rotating roller rotates accordingly. When one of its curved edges contacts the bottom of the conveyor belt 400, it transmits vibrations through tapping, causing the food on the conveyor belt 400 to bounce and flip, avoiding blind spots in the bottom sterilization process. The curved end face design reduces scratch damage to the conveyor belt 400 and extends the service life of the agitator plate 650. The diameter of the drive pulley 610 is larger than that of the driven pulley 630, causing the rotating roller to rotate at a higher speed than the conveyor belt 400, ensuring that the food is tapped and flipped multiple times during transport, improving the uniformity of sterilization.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, an adjustment mechanism 700 is provided on the base 100. The adjustment mechanism 700 includes a slide groove 710 formed on the surface of the base 100. A mounting block 620 is slidably connected to the slide groove 710. An electric push rod 720 is fixedly connected to the slide groove 710, and the telescopic end of the electric push rod 720 is fixedly connected to the bottom of the mounting block 620. A limit groove 730 is formed on the surface of the base 100. A limit block 740 is slidably connected to the limit groove 730. A tension pulley 750 is rotatably connected to one side of the limit block 740. A spring 760 is fixedly connected between the bottom of the limit block 740 and the limit groove 730. An annular groove is formed on the outer circumferential surface of the tension pulley 750. The width of the annular groove is adapted to the width of the transmission belt 640, and the inner sidewall of the annular groove is provided with anti-slip texture.

[0031] In this embodiment, the adjustment mechanism 700 can adapt to food of different specifications. When processing thicker or larger food, the electric push rod 720 is activated, and its telescopic end pushes the mounting block 620 to slide up and down along the slide groove 710, thereby driving the rotating roller to rise and fall synchronously, thereby adjusting the distance between the agitator plate 650 and the conveyor belt 400. When the distance is increased, the slapping force is enhanced, which is suitable for thick food. When the distance is reduced, the force is weakened, which prevents thin food from bouncing off the conveyor belt 400.

[0032] During the lifting and lowering of the mounting block 620, the limiting block 740 slides along the limiting groove 730 under the elastic force of the spring 760, driving the tensioning pulley 750 to tighten the transmission belt 640, ensuring stable transmission, ensuring belt tension when the height of the mounting block 620 changes, ensuring stable rotation speed of the rotating roller, ensuring uniform tapping frequency, and ensuring uniform sterilization.

[0033] Working principle: The food to be sterilized is fed into the sterilization area inside the protective cover 500 by the conveyor belt 400. The motor 200 drives the transmission roller 300 to rotate, which in turn drives the conveyor belt 400 to transport the food. At the same time, the rotating roller and the actuating plate 650 rotate synchronously through the transmission of the drive pulley 610, the transmission belt 640 and the driven pulley 630.

[0034] When the agitator plate 650 rotates to contact the bottom of the conveyor belt 400, it transmits vibration by slapping, causing the food on the conveyor belt 400 to bounce and roll due to the vibration, thus achieving all-round flipping; the microwave generator and ultraviolet germicidal lamp inside the protective cover 500 work synchronously, using the synergistic effect of microwave thermal effect and ultraviolet light to sterilize the flipped food without dead angles.

[0035] The height of the rotating roller is adjusted by the electric push rod 720, thereby adjusting the patting force. During the adjustment process, the tension pulley 750 automatically tightens the transmission belt 640 under the action of the spring 760 to ensure stable transmission. The sterilized food is sent out by the conveyor belt 400, completing the continuous sterilization operation.

[0036] It should be noted that the motor 200, transmission roller 300, conveyor belt 400, microwave generator, and ultraviolet germicidal lamp mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the motor 200, microwave generator, and ultraviolet germicidal lamp can be powered by mains power. The specific power supply method can be selected according to the situation and will not be elaborated here.
