Description
Technical Field
[0001] This invention relates to the field of ultraviolet sterilization technology, and in particular to an automated ultraviolet sterilization device for baking ingredients with a uniform turning function. Background Technology
[0002] With the continuous upgrading of food safety standards, baking ingredients such as flour, grains, and nuts are prone to carrying mold and bacteria. Traditional sun-drying and high-temperature sterilization can easily damage the flavor and nutrients of these ingredients, resulting in quality loss. To meet the hygiene requirements of large-scale production, automated ultraviolet sterilization equipment for baking ingredients has emerged. It can efficiently kill harmful microorganisms, ensuring the safety of baked goods, while balancing sterilization efficiency, ingredient quality, and environmental friendliness. However, existing ultraviolet sterilization equipment still has the following drawbacks: Existing UV sterilization equipment for baking ingredients still has significant technical shortcomings in practical applications. Most of these devices are equipped with only simple, conventional stirring mechanisms, resulting in a rigid operating mode. They can only perform simple stirring and turning of baking ingredients at a fixed speed and amplitude, lacking flexibility and intelligent adjustment capabilities. During sterilization, traditional equipment cannot perform intelligent variable frequency speed regulation based on material thickness, particle size, stacking state, and real-time stirring effect, maintaining a single stirring rhythm throughout. Materials cannot be layered and turned according to actual sterilization needs, making targeted sterilization difficult. Furthermore, existing equipment cannot be equipped with deep layering stirring functions in addition to variable frequency stirring. At high stirring speeds, the materials piled deep within the material layer cannot be effectively stirred, leaving these deeper layers blocked from UV light; at slower stirring speeds, the surface layers cannot be gently turned, leading to repeated stacking of surface materials. This single stirring method easily creates numerous sterilization dead zones, resulting in uneven light exposure and the inability to kill large areas of bacteria, severely reducing sterilization quality. Furthermore, the inability to reasonably match the turning rhythm with the duration of ultraviolet irradiation results in an imbalance in the distribution of sterilization time for materials, which not only restricts the overall sterilization efficiency but also makes it difficult to consistently meet the high standards of food hygiene and safety production requirements for baking ingredients. Summary of the Invention
[0003] Given that the existing technology has problems such as simple structure and rudimentary function of stirring mechanism, which not only restricts the overall sterilization efficiency, but also makes it difficult to consistently meet the high standards of food hygiene and safety production requirements of baking raw materials, an automated ultraviolet sterilization equipment for baking raw materials with uniform turning function is proposed.
[0004] This application provides an automated ultraviolet sterilization device for baking raw materials with uniform turning function. Its purpose is to carry out intelligent variable frequency speed regulation stirring. When the stirring speed is fast, the raw materials are stirred deeply, and when the stirring speed is slow, the raw materials are stirred shallowly, thereby improving the sterilization quality.
[0005] The technical solution of the present invention is: an automated ultraviolet sterilization equipment for baking raw materials with uniform turning function, including a sterilization box, a top cover on the top of the sterilization box, a discharge pipe at the bottom of the sterilization box, a feed pipe on one side of the top of the sterilization box, a number of ultraviolet lamps arranged in a ring array on the inner side of the top cover, an organic box on the top of the top cover, and a variable frequency deep and shallow stirring component arranged in the sterilization box. The variable frequency deep and shallow stirring component includes a stirring assembly installed in the sterilization chamber, a variable frequency assembly installed in the chassis, a friction assembly installed on the variable frequency assembly, and a deep and shallow stirring assembly installed in the chassis. The variable frequency deep and shallow stirring component is used to perform variable frequency deep and shallow stirring on the baking ingredients, and to sterilize the baking ingredients thoroughly. The stirring assembly includes an outer stirring shaft mounted on the top cover, the top of which is rotatably connected to the top of the inner side of the casing. The outer stirring shaft has a movable groove, and an inner stirring shaft is mounted inside the movable groove. Several stirring blades are arranged in a circular array on the inner stirring shaft, and the stirring blades have an S-shaped structure.
[0006] Furthermore, the frequency conversion component includes a first gear and a second gear arranged from bottom to top on the outer shaft of the stirring machine. A drive shaft is provided inside the machine housing. A third gear and a fourth gear are arranged from bottom to top on the drive shaft. The first gear is meshed with the third gear, and the second gear is meshed with the fourth gear. A drive motor is provided on the top of the machine housing, and the output shaft of the drive motor is fixedly connected to the drive shaft.
[0007] Furthermore, the friction assembly includes friction wheels symmetrically distributed on the drive shaft, with two friction wheels fixedly connected to the third gear and the fourth gear respectively, and two friction sleeves symmetrically distributed on the drive shaft, with the friction sleeves engaging with the corresponding friction wheels.
[0008] Furthermore, the depth component includes an adjusting rod disposed inside the chassis, and an adjusting spring is disposed between the adjusting rod and the chassis, with the adjusting spring sleeved on the outside of the adjusting rod.
[0009] Furthermore, the variable frequency deep and shallow stirring component also includes a reciprocating component and a lifting component installed in the chassis, and a labor-saving component and an adjustment component installed in the top cover; The reciprocating assembly includes a reciprocating sleeve mounted on a friction sleeve, a U-shaped plate between the two reciprocating sleeves, and a U-shaped plate fixedly connected to an adjusting rod.
[0010] Furthermore, the lifting assembly includes a fifth gear located at the bottom of the drive shaft, a sixth gear located inside the housing, the fifth gear meshing with the sixth gear, a connecting plate located on the top of the sixth gear, an arc-shaped plate located on the top of the connecting plate, and a first inclined surface located at both ends of the arc-shaped plate. The bottom of the adjusting rod is slidably connected to the top of the arc-shaped plate, the first inclined surface, and the top of the connecting plate.
[0011] Furthermore, the labor-saving component includes a labor-saving rod mounted on the chassis, with its top fixedly connected to an adjusting rod. A labor-saving ring is mounted at the bottom of the labor-saving rod, and several first U-shaped seats are arranged in a circular array at the bottom of the labor-saving ring. Several second U-shaped seats are arranged in a circular array on the top inner side of the top cover, and a labor-saving plate is mounted inside the second U-shaped seats. A collar is mounted on the inner shaft of the stirring assembly, and several third U-shaped seats are arranged in a circular array on the collar. One end of the labor-saving plate is movably connected to the inner side of the first U-shaped seat, and the other end of the labor-saving plate is movably connected to the inner side of the third U-shaped seat.
[0012] Furthermore, the adjustment assembly includes through slots symmetrically distributed at both ends of the effort-saving plate, and sliding rods are provided inside the two through slots. One sliding rod is fixedly connected to the inside of the first U-shaped seat, and the other sliding rod is fixedly connected to the inside of the third U-shaped seat.
[0013] The beneficial effects of this invention are: Utilizing variable frequency control technology, the equipment can flexibly adjust the stirring speed without manual intervention. It abandons the single-mode fixed-speed approach, precisely adapting to the raw material stirring requirements through variable frequency components, avoiding problems such as uneven material agitation and poor sterilization effects caused by fixed speeds. Simultaneously, the variable frequency adjustment can dynamically adjust according to actual working conditions, preventing raw material accumulation and matching the UV irradiation rhythm to improve sterilization effectiveness, adapting to large-scale production, and balancing efficiency and sterilization quality.
[0014] By adjusting the mixing depth to suit different needs, this system avoids the drawbacks of traditional equipment that can only stir the surface and cannot reach deeper ingredients. When the mixing speed is increased, it can deeply stir the bottom layer of ingredients, breaking up any accumulated blind spots; when the speed is slowed down, it can finely process the surface ingredients, ensuring that the ingredients are evenly spread. This layered mixing mode allows ultraviolet light to irradiate the baking ingredients over a large area, eliminating sterilization dead zones, while avoiding material loss caused by over-stirring. This achieves a dual improvement in sterilization effect and production efficiency, adapting to the processing needs of various baking ingredients.
[0015] By optimizing the linkage structure and gear transmission design, and combining them with labor-saving components, the resistance during the stirring process is significantly reduced, thus decreasing the motor load. Simultaneously, by utilizing the lever principle and frequency conversion control, deep material agitation and surface material fine processing can be achieved without the need for manual application of additional force. Compared to traditional equipment, it is not only easier to operate but also avoids component jamming and excessive wear, extending equipment lifespan. It also reduces manual intervention costs, ensuring continuous and stable operation. While maintaining sterilization effectiveness, it balances labor-saving and practicality, reducing production and maintenance costs. Attached Figure Description

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] Example 1, referring to Figures 1-8This invention provides a first embodiment of an automated ultraviolet sterilization device for baking ingredients with uniform material turning function. The device includes a sterilization chamber 1, a top cover 11 fixedly connected to the top of the sterilization chamber 1, a discharge pipe 12 fixedly connected to the bottom of the sterilization chamber 1, a feed pipe 13 fixedly connected to one side of the top of the sterilization chamber 1, and a plurality of ultraviolet lamps 14 fixedly connected in a circular array on the inner side of the top cover 11. A housing 15 is fixedly connected to the top of the top cover 11. The device also includes a variable frequency deep / shallow stirring component installed inside the sterilization chamber 1. The variable frequency deep / shallow stirring component includes a stirring assembly 2 installed inside the sterilization chamber 1, and the housing 15 contains... The unit is equipped with a frequency converter 3, on which a friction component 4 is installed. A deep and shallow mixing component 5 is also installed inside the casing 15. The frequency converter deep and shallow mixing component is used to perform frequency converter deep and shallow mixing on baking ingredients and to sterilize the baking ingredients. The mixing component 2 includes an outer mixing shaft 21 rotatably connected to the top cover 11. The top of the outer mixing shaft 21 is rotatably connected to the top of the inner side of the casing 15. A movable groove is opened on the outer mixing shaft 21. An inner mixing shaft 22 is slidably connected to the inner side of the movable groove. Several mixing blades 23 are fixedly connected in a ring array on the inner mixing shaft 22. The mixing blades 23 have an S-shaped structure.
[0020] Specifically, the stirring blades 23 are inclined. The baking raw materials enter the sterilization chamber 1 through the feed pipe 13 on one side of the top. Several ultraviolet lamps 14 arranged in a ring array on the inner side of the top cover 11 are activated simultaneously, continuously releasing ultraviolet light to provide light source support for the sterilization operation. The frequency converter 3 is activated, driving the stirring component 2 to operate, realizing frequency conversion adjustment of the stirring speed to adapt to the stirring needs of different raw materials. The outer stirring shaft 21 rotates under the drive of the frequency converter 3, and the inner stirring shaft 22 slides within the outer stirring shaft 21 through a movable groove. With the adjustment of the depth component 5, the stirring depth can be flexibly switched. When the stirring speed is fast, the depth component 5 drives the inner stirring shaft 22 to slide downward, so that the S-shaped inclined stirring blades 23 penetrate deep into the raw materials and fully agitate the deep raw materials; when the stirring speed is slowed down, the inner stirring shaft 22 slides upward, and the stirring blades 23 only gently turn over the shallow raw materials. The raw materials are evenly agitated within the sterilization chamber 1, ensuring complete exposure to ultraviolet light 14 throughout the process. After thorough sterilization, the raw materials are discharged through the outlet pipe 12 at the bottom of the sterilization chamber 1. This targeted mixing of the raw materials at both the deep and shallow layers avoids the sterilization blind spots of traditional equipment, ensuring all raw materials are fully exposed to ultraviolet light, significantly improving the sterilization effect and meeting food hygiene standards. Compared to traditional fixed mixing, this reduces material splashing and loss, preserving the original flavor and nutrients of the baking ingredients. No manual intervention is required to control the mixing speed and depth; the entire process of feeding, mixing, sterilization, and discharging is automated, adaptable to large-scale production, reducing labor costs and improving production efficiency.
[0021] Reference Figure 6 and Figure 7The frequency converter 3 includes a first gear 31 and a second gear 32 fixedly mounted on the outer shaft 21 of the stirring unit from bottom to top. A drive shaft 33 is rotatably connected to the inner side of the housing 15. A third gear 34 and a fourth gear 35 are movably mounted on the drive shaft 33 from bottom to top. The first gear 31 is meshed with the third gear 34, and the second gear 32 is meshed with the fourth gear 35. A drive motor 36 is provided on the top of the housing 15. The output shaft of the drive motor 36 is fixedly connected to the drive shaft 33.
[0022] Specifically, the diameter of the first gear 31 is smaller than the diameters of the second gear 32 and the third gear 34, while the diameter of the second gear 32 is larger than the diameter of the fourth gear 35. Since the diameter of the first gear 31 is smaller than that of the third gear 34, when the drive motor 36 drives the drive shaft 33 to rotate, and the drive shaft 33 drives the third gear 34 to rotate, the inner stirring shaft 22 rotates via gear transmission. At this time, because the larger gear drives the smaller gear, the inner stirring shaft 22 rotates at a relatively fast speed. When the drive shaft 33 drives the fourth gear 35 to rotate, because the smaller gear drives the larger gear, the inner stirring shaft 22 rotates at a slower speed. This allows for real-time adjustment of the rotation speed of the inner stirring shaft 22, achieving variable frequency stirring of the baking ingredients.
[0023] Reference Figure 7 The friction assembly 4 includes friction wheels 41 that are symmetrically distributed and movably sleeved on the drive shaft 33. The two friction wheels 41 are fixedly connected to the third gear 34 and the fourth gear 35 respectively. The drive shaft 33 has two friction sleeves 42 that are symmetrically distributed and slidably connected. The friction sleeves 42 are sleeved with the corresponding friction wheels 41.
[0024] Specifically, when the bottom friction sleeve 42 is engaged with the corresponding friction wheel 41, the top friction sleeve 42 is not in contact with the corresponding friction wheel 41. Since the drive shaft 33 and the friction sleeve 42 are connected by a limiting sliding connection, when the drive shaft 33 rotates, it drives the friction sleeve 42 to rotate. Under the action of friction, it drives the friction wheel 41 to rotate, which in turn drives the third gear 34 to rotate. The inner side of the friction sleeve 42 and the outer side of the friction wheel 41 are both provided with a second inclined surface to facilitate the insertion of the friction wheel 41 into the inner side of the friction sleeve 42. When the top friction sleeve 42 is engaged with the corresponding friction wheel 41, the bottom friction sleeve 42 is not in contact with the corresponding friction wheel 41, causing the fourth gear 35 to rotate.
[0025] Example 2, refer to Figure 8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the depth component 5 includes an adjusting rod 51 that is slidably connected inside the housing 15. An adjusting spring 52 is fixedly connected between the adjusting rod 51 and the housing 15. The adjusting spring 52 is sleeved on the outside of the adjusting rod 51.
[0026] Specifically, when the adjusting rod 51 is subjected to force and moves upward, it stretches the adjusting spring 52, causing the stirring inner shaft 22 to move downward inside the movable groove and insert deeper into the baking ingredients. At this time, the stirring inner shaft 22 rotates faster, the adjusting rod 51 is not subjected to force, the adjusting spring 52 will return to its original position, causing the adjusting rod 51 to move downward, causing the stirring inner shaft 22 to move upward inside the movable groove, stirring the surface of the baking ingredients, and the stirring inner shaft 22 rotates at a slower speed.
[0027] Reference Figure 8 The variable frequency deep and shallow stirring component also includes a reciprocating assembly 6 and a lifting assembly 7 installed in the housing 15, and a labor-saving assembly 8 and an adjusting assembly 9 installed in the top cover 11; the reciprocating assembly 6 includes a reciprocating sleeve 61 fixedly sleeved on the friction sleeve 42, and a U-shaped plate 62 fixedly connected between the two reciprocating sleeves 61, and the U-shaped plate 62 is fixedly connected to the adjusting rod 51.
[0028] Specifically, when the adjusting rod 51 is subjected to force and moves upward, it causes the U-shaped plate 62 to move upward, so that the friction sleeve 42 at the bottom is engaged with the corresponding friction wheel 41. At this time, the third gear 34 drives the first gear 31 to rotate, which is the large gear driving the small gear, making the inner stirring shaft 22 rotate faster. When the adjusting rod 51 is not subjected to force and moves downward, it causes the U-shaped plate 62 to move downward, so that the friction sleeve 42 at the top is engaged with the corresponding friction wheel 41. At this time, the fourth gear 35 drives the second gear 32 to rotate, which is the small gear driving the large gear, making the inner stirring shaft 22 rotate at a slower speed.
[0029] Reference Figure 8 The lifting assembly 7 includes a fifth gear 71 fixedly sleeved on the bottom of the drive shaft 33, a sixth gear 72 rotatably connected to the inside of the housing 15, the fifth gear 71 and the sixth gear 72 meshing together, a connecting plate 73 fixedly connected to the top of the sixth gear 72, an arc plate 74 fixedly connected to the top of the connecting plate 73, and a first inclined surface opened at both ends of the arc plate 74. The bottom of the adjusting rod 51 is slidably connected to the top of the arc plate 74, the first inclined surface and the top of the connecting plate 73.
[0030] Specifically, the diameter of the fifth gear 71 is smaller than that of the sixth gear 72, and the number of teeth in the fifth gear 71 is less than that in the sixth gear 72. When the drive shaft 33 drives the fifth gear 71 to rotate, because the diameter of the fifth gear 71 is smaller and the diameter of the sixth gear 72 is larger, and the number of teeth in the fifth gear 71 is less than that in the sixth gear 72, when the fifth gear 71 rotates one revolution, the sixth gear 72 does not rotate one revolution. This drives the connecting plate 73 and the arc plate 74 to rotate. When the arc plate 74 rotates to the bottom of the adjusting rod 51, under the action of the first inclined surface, it drives the adjusting rod. Adjusting rod 51 moves upward, causing it to slide on top of the arc-shaped plate 74. When the drive shaft 33 rotates once, it drives the inner stirring shaft 22 to rotate once. At this time, the sixth gear 72 has not yet rotated once. That is, adjusting rod 51 slides on top of the arc-shaped plate 74 and has not fallen down. When adjusting rod 51 is at the top of the arc-shaped plate 74, the inner stirring shaft 22 is inserted inside the baking ingredients. Even when the inner stirring shaft 22 rotates once, it remains inserted inside the baking ingredients, preventing frequent movement of the inner stirring shaft 22 inside and outside the baking ingredients. The remaining structure is the same as in Embodiment 1.
[0031] Example 3, referring to Figure 9 and Figure 10 This is the third embodiment of the present invention, which differs from the second embodiment in that: the labor-saving component 8 includes a labor-saving rod 81 slidably connected to the housing 15, the top of the labor-saving rod 81 is fixedly connected to the adjusting rod 51, the bottom of the labor-saving rod 81 is fixedly connected to a labor-saving ring 82, the bottom of the labor-saving ring 82 is fixedly connected to a plurality of first U-shaped seats 83 in a circular array, the top of the inner side of the top cover 11 is fixedly connected to a plurality of second U-shaped seats 84 in a circular array, the inner side of the second U-shaped seats 84 is rotatably connected to a labor-saving plate 85, the inner shaft 22 of the stirring is rotatably connected to a collar 86, the collar 86 is fixedly connected to a plurality of third U-shaped seats 87 in a circular array, one end of the labor-saving plate 85 is movably connected to the inner side of the first U-shaped seat 83, and the other end of the labor-saving plate 85 is movably connected to the inner side of the third U-shaped seat 87.
[0032] Specifically, when the adjusting rod 51 is moved upward under force, it drives the force-saving rod 81 to move upward, which in turn drives the force-saving ring 82 to move upward, causing the first U-shaped seat 83 to move upward. This causes the force-saving plate 85 to rotate upward at one end and downward at the other. The second U-shaped seat 84 is located close to the third U-shaped seat 87. Therefore, the distance between the first U-shaped seat 83 and the second U-shaped seat 84 on the force-saving plate 85 is greater than the distance between the second U-shaped seat 84 and the third U-shaped seat 87. Consequently, when the first U-shaped seat 83 moves upward, only a small force is required to move the third U-shaped seat 87 downward, which in turn drives the stirring inner shaft 22 to move downward, thus achieving the effect of saving effort.
[0033] Reference Figure 9The adjustment component 9 includes through slots 91 symmetrically distributed at both ends of the force-saving plate 85. Sliding rods 92 are slidably connected to the inner side of each of the two through slots 91. One sliding rod 92 is fixedly connected to the inner side of the first U-shaped seat 83, and the other sliding rod 92 is fixedly connected to the inner side of the third U-shaped seat 87.
[0034] Specifically, when the labor-saving plate 85 rotates, the first U-shaped seat 83 moves vertically upward and the third U-shaped seat 87 moves vertically downward, causing both the first U-shaped seat 83 and the third U-shaped seat 87 to move away from the labor-saving plate 85, so that the sliding rod 92 slides inside the through groove 91, thus playing an adjustment role. The rest of the structure is the same as that of Embodiment 2.
[0035] Based on embodiments 1-3, the working principle of the present invention is as follows: The drive motor 36 is started, driving the drive shaft 33 to rotate. When the adjusting rod 51 slides on the top of the connecting plate 73, the friction sleeve 42 at the top is fitted onto the corresponding friction wheel 41. The drive shaft 33 drives the friction sleeve 42 to rotate, and under the action of friction, drives the friction wheel 41 to rotate, which in turn drives the fourth gear 35 to rotate, and then drives the second gear 32 to rotate. At this time, the small gear drives the large gear to rotate, causing the outer stirring shaft 21 to rotate slowly, causing the inner stirring shaft 22 to rotate as well, driving the stirring blade 23 to rotate, thus stirring the baking ingredients. At this time, the effort-saving rod 81 drives the effort-saving ring 82 to move downwards, causing the first U-shaped seat 83 to move vertically downwards and the third U-shaped seat 87 to move vertically upwards. The sliding rod 92 slides inside the through groove 91, playing an adjusting role, causing the collar 86 to move upwards, and the inner stirring shaft 22 to move upwards inside the movable groove, driving the stirring blade 23 to stir the surface of the baking ingredients. When the adjusting rod 51 slides to the top of the arc plate 74 under the action of the first inclined plane, the arc plate 74 drives the adjusting rod 51 to move upward, which in turn drives the U-shaped plate 62 to move upward, so that the friction sleeve 42 at the bottom is fitted with the corresponding friction wheel 41. When the drive shaft 33 rotates, it drives the friction sleeve 42 to rotate. Under the action of friction, it drives the friction wheel 41 to rotate, drives the third gear 34 to rotate, and then drives the first gear 31 to rotate. At this time, the large gear drives the small gear to rotate, and the stirring inner shaft 22 rotates faster. The adjusting rod 51 drives the effort-saving rod 81 to move upward, drives the effort-saving ring 82 to move upward, so that the first U-shaped seat 83 moves vertically upward, the third U-shaped seat 87 moves vertically downward, so that the collar 86 moves downward, and the stirring inner shaft 22 moves downward, stirring the inside of the baking ingredients.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
