Description

Technical Field

[0001] The utility model relates to the technical field of air-drying devices, and particularly relates to a pickled egg air-drying device. Background Art

[0002] In the production and processing process of pickled eggs, since foreign matters are inevitably adhered to the eggshells, it is necessary to perform cleaning, air-drying, sterilization, etc., so as to ensure the quality of the eggs, extend the shelf life, and meet the requirements of subsequent sorting or deep processing processes. Among them, the traditional air-drying device uses a large fan, with a slow air-drying speed and low efficiency, which is not conducive to ensuring the quality of the eggs and extending the shelf life.

[0003] Chinese Patent CN202406937U discloses an egg air-drying device, which includes a frame and a conveying mechanism located on the frame. The characteristics are as follows: a plurality of air blowers are arranged at intervals above the frame along the egg feeding direction, and a plurality of air supply frames corresponding to each air blower are suspended below the frame through suspension rods. The air supply frame includes an air supply main pipe and a plurality of air supply branch pipes vertically connected to the air supply main pipe. A plurality of air supply ports facing the conveying mechanism are opened on the lower side of the air supply branch pipe, and the air supply main pipe is connected to the air outlet pipe of the air blower. The utility model uses the natural wind generated by the air blower to quickly air-dry the washed eggs, which is conducive to ensuring the quality of the eggs and extending the shelf life of the eggs.

[0004] Chinese Patent CN204763099U discloses an air-drying and output device for egg cleaning, belonging to the technical field of poultry egg cleaning. It includes a frame, a motor and a speed reducer. The output end of the motor is connected to the input end of the speed reducer. A box body is arranged in the middle section of the frame. A plurality of rotating rollers are arranged in the box body. Pulley wheels are respectively arranged at both ends of the rotating rollers. The pulley wheels are all connected to an annular belt. The belt is driven by a driving wheel, and the driving wheel is connected to the output end of the speed reducer; an air blower assembly is arranged above the box body. On the one hand, the air-drying device is arranged above the conveyor belt in this technical solution. On the other hand, the eggs are slowly conveyed by the rotating rollers, and the eggs are continuously turned over with the rotating rollers during the conveying process, so that the air blower can dry the eggs in all directions, achieving the effect of drying and conveying in all directions, ensuring the drying and cleanliness of the eggs, preparing for sorting and packaging, and ensuring the ex-factory quality of the products.

[0005] Chinese Patent CN209840577U discloses an egg air dryer, which includes a frame, an air outlet device, and a conveying component. The conveying component conveys eggs. The air outlet device is fixedly installed on the frame, and the air outlet device is connected to an external hair dryer; the air outlet device is located above the conveying component, and the air outlet device is provided with a plurality of air outlets, and the plurality of air outlets face the conveying component. The egg air dryer provided by the present invention sets an air outlet device above the conveying component to air-dry the washed eggs. After the eggs are air-dried by the air dryer, most of the residual water on the eggshell surface is removed; the air outlet device is set in a fan shape, and an air outlet is provided at the tip of the fan shape. Under a constant wind speed, the air-drying efficiency is increased; and the setting of the diversion pipe enables the water on the eggs to flow along a certain direction, and the gap between the diversion pipes can achieve a better ventilation and drying effect.

[0006] Although the above technologies have improved the air-drying efficiency to a certain extent and improved the air-drying effect, they all have complex structures and large energy losses. In particular, there are air-supply stagnant areas, and the problem that the rotating rollers in contact with the eggs will also be stained with water stains during the air-drying process is not considered. As a result, the eggs need to be air-dried repeatedly, and the air-drying efficiency cannot be fundamentally improved. Summary of the Utility Model

[0028] The following describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0029] The following illustrates the embodiments of the present disclosure through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0030] Refer to Figures 1-5, an embodiment of the present utility model provides a pickled egg air-drying device, including: a blower 1, an air box 2, and a conveying roller path 3. A plurality of roller shafts 4 that are arranged side by side and driven are evenly distributed between the left and right sides of the conveying roller path 3. The roller shafts 4 are of a hollow structure. The air box 2 is fixed directly above the conveying roller path 3. Specifically, the air box 2 is fixed above the conveying roller path 3 through a bracket. The air box 2 is of a square structure and is a hollow shell structure. The blower 1 is connected to the air box 2. A plurality of rows of vertically downward main nozzles 5 are evenly distributed along the conveying direction of the conveying roller path 3 at the bottom of the air box 2. Inclined downward secondary nozzles 6 are symmetrically arranged on the front and rear sides of the main nozzles 5 respectively. Specifically, the distance between the nozzle outlet and the surface of the egg product is: 15 cm to 30 cm.

[0031] In the above technical solution, by adopting the air box 2 with a hollow shell structure, there is no obstruction inside, which can effectively reduce the loss of air flow energy and make the air flow have a high degree of uniformity, avoiding uneven air-drying of egg products; and by adopting the jet cooperation structure of the main nozzles 5 and the secondary nozzles 6, it can effectively eliminate the stagnant air area of the air supply and achieve full coverage of the air-drying area of the egg products; further, by adopting the roller shafts 4 with a hollow structure, during the conveying process, the roller shafts 4 are reduced or avoided from being stained with water stains, avoiding repeated air-drying of egg products and improving the air-drying efficiency of egg products.

[0032] During operation, the egg products to be air-dried are placed between the roller shafts 4 from the feeding end of the conveying roller path 3. Driven by the roller shafts 4, the egg products are transported along the conveying roller path 3. The blower 1 blows air into the air box 2 and then blows out from the main nozzles 5 and the secondary nozzles 6 respectively, so as to air-dry the surface of the egg products.

[0033] In some embodiments, a plurality of arc-shaped recessed parts are evenly distributed along the length direction of the roller shafts 4. A card slot 13 for placing pickled eggs is formed between the arc-shaped recessed parts of adjacent roller shafts 4. The design of this structural solution makes the placement of egg products more stable, the distribution of egg products more uniform, ensuring uniform air-drying, and not easily occurring situations such as position deviation and collision, preventing damage to egg products.

[0034] In some embodiments, sprocket drive groups are respectively arranged on both sides of the conveying roller path 3. The sprocket drive group includes: a driving sprocket 7, a driven sprocket 8, and a chain 9. The driving sprocket 7 and the driven sprocket 8 are respectively rotatably connected to both ends of the conveying roller path 3. The chain 9 is drivingly connected between the driving sprocket 7 and the driven sprocket 8. Both ends of the roller shafts 4 are respectively connected between the chains 9 on both sides. The driving sprocket 7 is driven by a motor. The conveying roller path 3 drives the roller shafts 4 between the chains 9 on both sides to move forward through the sprocket drive groups on both sides, thereby driving the egg products to be transported forward for air-drying.

[0035] In some embodiments, both ends of the roller shaft 4 are rotatably connected to the chains 9 on both sides. At least one end of each of the two ends of the roller shaft 4 is fixed with a gear 10. A rack is fixed below the upper roller shaft 4 of the conveying roller path 3, and the length direction of the rack is the same as the driving direction of the conveying roller path 3. The gear 10 meshes with the rack. During operation, the chain 9 drives the roller shaft 4 to move forward, and at the same time, the gear 10 rotates under the action of the rack, thereby driving the roller shaft 4 to rotate, realizing continuous flipping of the eggs, ensuring uniform air drying on the surface of the eggs, avoiding air drying at the same position repeatedly, and improving the air drying efficiency of the eggs.

[0036] In some embodiments, a water collecting tray 11 is arranged below the upper roller shaft 4 of the conveying roller path 3. The water collecting tray 11 is used to receive and collect the water droplets blown off during the air drying process, preventing the water droplets from falling onto the lower roller shaft 4 and affecting the air drying efficiency.

[0037] In some embodiments, a baffle 12 is arranged above the water collecting tray 11, and through holes are evenly distributed on the surface of the baffle 12. Specifically, the distance between the baffle 12 and the surface of the eggs is 10 cm to 20 cm. The baffle 12 plays a role in blocking the wind and rebounding. After the first wave of air drying air flow blows down through the eggs and encounters the perforated baffle 12, the air flow is rebounded, forming an admixture with the second wave of air drying air flow blown out by both the main nozzle 5 and the auxiliary nozzle 6, strengthening the air flow disturbance on the surface of the eggs, which is beneficial to further improving the air drying efficiency.

[0038] Further, the bottom of the water collecting tray 11 is of a slope-shaped structure, and a drain outlet is arranged at the bottom of the slope of the water collecting tray 11. This structural design facilitates the discharge of the water in the water collecting tray 11.

[0039] In some embodiments, both the main nozzle 5 and the auxiliary nozzle 6 are of a strip-shaped opening structure, and the length direction of the strip-shaped opening is the same as the length direction of the roller shaft 4. In some other embodiments, the main nozzle 5 and the auxiliary nozzle 6 can adopt air outlet holes evenly spaced apart, and the air outlet holes are arranged in a straight line.

[0040] In some embodiments, the included angle between the main nozzle 5 and the auxiliary nozzle 6 is 15° to 30°. Driven by the high-speed air flow of the main nozzle 5, low-pressure areas are formed on both sides of the main nozzle 5, and the air flow of the auxiliary nozzle 6 can just fill the low-pressure areas. Coupled with the continuous effect formed by the mutual adhesion of the auxiliary nozzles 6 between each row of nozzles, the air supply stagnant area is completely eliminated.

[0041] In some embodiments, an inclined guide plate 14 is arranged at the feeding end of the conveying roller path 3. The guide plate 14 is wavy, and the groove of the guide plate 14 faces the card slot 13. The structural design of the guide plate 14 facilitates the smooth placement of the eggs in the card slot 13 and prevents damage to the eggs.
