Abstract
Description
Technical Field
[0001] This utility model belongs to the field of salted egg yolk sorting technology, specifically relating to a salted egg yolk quality sorter. Background Technology
[0002] Salted egg yolks, as a core product in the field of deep processing of poultry eggs, are widely used in food processing scenarios such as mooncakes, zongzi, and pastries due to their unique flavor. The market's standardization requirements for their quality continue to rise. In the quality evaluation system of salted egg yolks, diameter is one of the core indicators. Salted egg yolks with larger diameters are usually accompanied by a fuller oil content and a better taste, while products with smaller diameters have a bland flavor and poor sand-like effect. They need to be graded and priced or adapted to different processing needs. Therefore, precise sorting by diameter has become a key process in the processing of salted egg yolks. Currently, the sorting of salted egg yolks in the industry mainly relies on manual sorting. Operators manually classify salted egg yolks of different diameters into corresponding collection containers by visual observation or simple calipers. This method has significant drawbacks. Manual judgment is easily affected by fatigue and experience differences, resulting in large fluctuations in sorting accuracy and difficulty in ensuring specification consistency. This directly affects the standardized production of downstream products and brand reputation. Moreover, the average daily processing capacity per person is only a few thousand eggs, which is labor-intensive and inefficient, and can no longer meet the production capacity needs of large-scale egg product enterprises. In view of the above-mentioned technological status, there is an urgent need for a salted egg yolk sorting device that is simple in structure and easy to operate. Utility Model Content
[0003] The purpose of this invention is to provide a salted egg yolk quality sorter that can accurately sort salted egg yolks by diameter, avoid human judgment errors, ensure consistent specifications, and significantly improve sorting efficiency.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0015] Example 1: like Figures 1-4 As shown, a salted egg yolk quality sorter includes a base plate 1, two first supports 2 are fixed to the top of the base plate 1, and two first mounting plates 4 and two second mounting plates 17 are respectively fixed to the top of the two first supports 2 close to each other. A sorting half bowl 3 is installed between the two first mounting plates 4 and the two second mounting plates 17, and an adjustment structure is installed between the two sorting half bowls 3. Multiple springs 10 are installed on the top of the base plate 1 and at the bottom of the sorting half-bowl 3, as shown in the attached diagram. Figure 2 A limiting rod is fixed to the top of the base plate 1 and inside each spring 10. The limiting rod is slidably connected to the movable piece 9. This arrangement allows the limiting rod to limit the spring 10, preventing the spring 10 from tilting when compressed. A movable piece 9 is fixed to the top of the spring 10, and a receiving half-bowl 11 is installed inside the movable piece 9. The receiving half-bowl 11 is semi-open. A blocking structure is provided on the top of the base plate 1 at the position where the receiving half-bowl 11 faces the opening. (See attached diagram) Figure 4 The blocking structure includes two second supports 13 fixed to the top of the base plate 1. The top of the two second supports 13 are fixed with a blocking plate 12 close to each other. The blocking plate 12 is set on one side of the opening of the receiving half bowl 11. By setting the blocking plate 12, the blocking plate 12 can block the salted egg yolks that are staying on the receiving half bowl 11 for a certain period of time. The top of the base plate 1 and the bottom of the receiving half bowl 11 are fixed with a guide belt 15. When sorting salted egg yolks by quality, a conveyor belt or similar component can guide the yolks between two sorting bowls 3. A circular hole forms between these bowls. Larger diameter yolks remain in the sorting bowls 3 and are collected by workers or robotic arms. Smaller yolks, of lower quality, fall through the hole into the receiving bowl 11. Here, the baffle plate 12 prevents them from falling through the opening, and their weight compresses the spring 10, causing the spring 1... With zero compression, the receiving half bowl 11 moves downward until it reaches the lower part of the baffle plate 12, causing the baffle plate 12 to release its obstruction of the salted egg yolk. At this point, the salted egg yolk falls out of the receiving half bowl 11 and rolls to the top of the guide belt 15. The guide belt 15 collects the salted egg yolk. The baffle plate 12 prevents the salted egg yolk from rolling directly into the guide belt 15. Instead, the salted egg yolk rolls onto the guide belt 15 when it falls with the receiving half bowl 11 and is not far from it, thus ensuring the integrity of the salted egg yolk and preventing it from breaking. This setup allows the device to collect high-quality salted egg yolks manually or by robotic arm, avoiding significant damage and enabling better processing. Lower-quality salted egg yolks can be collected uniformly via the guide belt 15, allowing for faster and more efficient collection.
[0016] See attached document Figure 3 The adjustment structure includes a reverse screw 6, which is rotatably connected between two first mounting plates 4. The two ends of the two sorting half-bowls 3 are respectively fixed with a first protruding block 5 and a second protruding block 18. The outer sides of the two ends of the reverse screw 6 are respectively threaded to the two first protruding blocks 5. A guide rod 8 is fixed between the two second mounting plates 17, and the guide rod 8 is slidably connected to the two second protruding blocks 18. A motor 7 is installed on the outer side of one of the first mounting plates 4, and the output end of the motor 7 is connected to the end of the reverse screw 6. When it is necessary to adjust the diameter of the collected high-quality salted egg yolks, the motor 7 can be driven so that the output end of the motor 7 drives the reverse screw 6 to rotate. The reverse screw 6 is threadedly connected to the two first protruding blocks 5 and limited by the guide rod 8 and the second protruding block 18. The threads at both ends of the reverse screw 6 turn in opposite directions, so that the two sorting half bowls 3 can move toward each other or toward each other, thereby adjusting the diameter of the salted egg yolks to be collected.
[0017] Example 2: This embodiment makes further technical improvements based on Embodiment 1, and its technical effects and features are as follows: See attached document Figure 3Multiple guide strips 14 are fixed to the bottom of each of the two sorting half-bowls 3, with the bottom of the guide strips 14 pointing towards the center of the receiving half-bowl 11. This arrangement allows the egg yolk oil adhering to the sorting half-bowl 3 to flow through the guide strips 14 to the center of the receiving half-bowl 11. The guide strips 14 are made of elastic material, such as rubber or silicone, so that when the small-diameter salted egg yolks fall, the guide strips 14 can deform, thus preventing the guide strips 14 from obstructing the fall of the salted egg yolks. The top of the guide belt 15 and directly below the receiving half-bowl 11 are evenly provided with through holes 16. The egg yolk oil falling through the guide strips 14 and the egg yolk oil in the receiving half-bowl 11 itself can drip onto the through holes 16, thus allowing the through holes 16 to collect the egg yolk oil, which the factory can then decide whether to use or discard.
[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
