Abstract
Description
Technical Field
[0001] This utility model relates to the field of braised egg production technology, specifically a pickling device for braised egg production. Background Technology
[0002] Boiled eggs (usually chicken eggs, duck eggs, etc.) are soaked in a brine mainly composed of soy sauce, spices, sugar, salt, etc. After a period of time, the surface and inside of the eggs absorb the flavors, forming fragrant and colored braised eggs.
[0003] An investigation revealed a utility model patent (publication number: CN218869386U) disclosing a marinating device for producing hard-boiled eggs. This device solves the problems of easily damaged suction pumps and inconvenient cleaning of marinade in current marinating devices. The device includes a marinating box with a hinge fixed to the rear of the top surface. A door is fixed to the other end of the hinge. An air pump is fixed to the bottom of the marinating box, and the air pump's outlet is connected to a first exhaust pipe. By placing the air pump at the bottom of the marinating box, it avoids contact with the interior, allowing eggs to move within the storage compartment and facilitating pump maintenance and replacement, thus extending its lifespan. The marinade box provides unified storage of the marinade, and the first exhaust pipe blows air into the marinade box, allowing water that has been in full contact with the marinade to drain out.
[0004] While the aforementioned patent utilizes an air pump design that prevents it from contacting the interior of the marinating box—allowing for egg movement within the storage compartment and facilitating pump maintenance and replacement, thus extending its lifespan—the marinade box provides unified storage of the marinade, and the first exhaust pipe blows air into the box to drain any water that has been in contact with the marinade. However, during the marinating process, sedimentation occurs at the bottom of the box, resulting in varying concentrations and inconsistent saltiness in the marinated eggs. This necessitates more marinade to cover the bottom area and overcome the problem of localized high salt content caused by sedimentation, thus increasing raw material consumption and costs.
[0005] Therefore, this utility model provides a pickling device for the production of braised eggs to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects 1. With the circulation mechanism, the brine can be circulated during the marinating process. This circulation allows the spices, salt, sugar and other components in the brine to be distributed more evenly throughout the marinating container, avoiding local concentrations that are too high or too low. This ensures that the marinated eggs have a consistent flavor. Continuous circulation also helps to quickly transfer the flavor and saltiness of the brine to the eggshell surface and the egg white and yolk, shortening the marinating time and improving overall efficiency. 2. Through the vibration mechanism, the ultrasonic vibration in the mechanism can vibrate the brine inside the brine barrel during the marinating process. The micro-flow and kinetic energy transmission caused by the ultrasonic waves help the pigment to enter the eggshell and its surface more evenly, avoiding uneven color distribution and the appearance of spots or color differences. The vibration and cavitation phenomena improve the micro-mixing degree of the liquid, increase the contact area and mass transfer driving force between the egg and the brine, thereby shortening the marinating time and increasing the penetration rate.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This utility model provides a pickling device for the production of marinated eggs, such as... Figures 1-6 As shown, the pickling device for producing braised eggs includes a pickling barrel 1, a cover plate 2 is snapped onto the upper surface of the pickling barrel 1, a circulation mechanism is fixedly installed on one side of the upper surface of the cover plate 2, a stirring mechanism is fixedly connected to the middle of the upper surface of the cover plate 2, a pressure mechanism is magnetically attached to the outer surface of the pickling barrel 1, and a vibration mechanism is fixedly installed on the inner bottom wall of the pickling barrel 1. The circulation mechanism includes a circulation pump 3, the outer surface of which is fixedly installed on one side of the upper surface of the cover plate 2. The output end of the circulation pump 3 is fixedly connected to a water outlet pipe 4, and the input end of the circulation pump 3 is fixedly connected to a water inlet pipe 5. The outer surface of the water inlet pipe 5 is fixedly connected to the inside of the pickling barrel 1. When pickling the eggs, the circulation mechanism can circulate the brine. Circulation allows the spices, salt, sugar and other components in the brine to be distributed more evenly throughout the pickling container, avoiding local concentrations that are too high or too low, thus ensuring a consistent flavor in the eggs. Continuous circulation helps to quickly transfer the flavor and saltiness of the brine to the eggshell surface and the egg white, yolk and other parts inside, shortening the pickling time and improving overall efficiency.
[0019] The pressurizing mechanism includes a magnetic ring plate A 6, with a magnetic ring plate B 7 magnetically attached to the inner wall of magnetic ring plate A 6. Magnetic ring plates A 6 and B 7 are magnetically attracted to each other and magnetically clamped to the outer surface of the pickling barrel 1. A heating plate 8 is fixedly connected to the inner wall of magnetic ring plate B 7. When the heating plate 8 is activated, the brine temperature is kept moderate. When the operator pulls the moving handle 16, the moving handle 16 moves up and down, causing magnetic ring plate A 6 to move. Magnetic ring plate A 6 then moves magnetic ring plate B 7, which in turn moves the heating plate 8. The heating plate 8 presses the braised eggs downwards, facilitating their settling at the bottom of the pickling barrel 1.
[0020] The stirring mechanism includes a drive motor 9. The outer surface of the drive motor 9 is fixedly installed in the middle of the upper surface of the cover plate 2. The output end of the drive motor 9 is splinedly connected to a connecting rod 10. One end of the connecting rod 10 is fixedly connected to a spiral stirring rod 11. When the drive motor 9 is started, the drive motor 9 rotates, driving the connecting rod 10 and the spiral stirring rod 11 to rotate. The spiral stirring rod 11 stirs the brine evenly.
[0021] The vibration mechanism includes a housing 12, the outer surface of which is fixedly connected to the inner bottom wall of the pickling barrel 1. A vibration tube 13 is fixedly connected to the inner side wall of the housing 12, and an ultrasonic generator 14 is fixedly connected to the outer surface of the vibration tube 13. When pickling hard-boiled eggs, the ultrasonic vibration in the vibration mechanism can vibrate the brine inside the pickling barrel 1. The micro-flow and kinetic energy transmission caused by the ultrasonic waves help the pigment to enter the eggshell and its surface more evenly, avoiding uneven color distribution and the appearance of spots or color differences. Vibration and cavitation phenomena improve the micro-mixing degree of the liquid, increase the contact area and mass transfer driving force between the egg and the brine, thereby shortening the pickling time and increasing the penetration rate.
[0022] A placement basket 15 is fixedly connected inside the pickling barrel 1. The placement basket 15 is a hollow woven basket, which serves to support the eggs and facilitates their storage.
[0023] A movable ring handle 16 is fixedly connected to the outer surface of magnetic ring plate 6. An anti-slip sleeve is fixedly connected to the outer surface of the movable ring handle 16. The movable ring handle 16 plays a control role, making it easy to move magnetic ring plate 6 up and down.
[0024] The bottom of the pickling barrel 1 is fixedly connected to a base 17, and the bottom of the base 17 is fixedly connected to an anti-slip pad. The base 17 serves to bear the weight, and the anti-slip pad at the bottom helps to increase friction.
[0025] Specifically, the brine is placed in the pickling barrel 1, and the braised eggs are placed inside the pickling barrel 1, falling into the placement basket 15. The eggs are soaked and pickled in the brine. The heating plate 8 is activated to maintain a moderate temperature in the brine. A person pulls the moving handle 16. As the moving handle 16 moves up and down, it moves the A magnetic ring plate 6. The A magnetic ring plate 6 moves the B magnetic ring plate 7 through magnetic force. The B magnetic ring plate 7 moves the heating plate 8, which presses the braised eggs downwards, making it easier for the braised eggs to settle at the bottom of the pickling barrel 1. Then, the drive motor 9 is activated. When the drive motor 9 rotates, it drives the connecting rod 10 and the spiral stirring rod 11 to rotate. The spiral stirring rod 11 stirs the brine. After ensuring uniformity, the ultrasonic generator 14 is activated, which vibrates the vibrating tube 13 through the outer shell 12. The micro-flow and kinetic energy transmission caused by the ultrasonic waves help the pigment to enter the outer shell and surface of the egg more evenly, avoiding uneven color distribution and the appearance of spots or color differences. Then, the circulation pump 3 is activated. The circulation pump 3 draws the brine in the upper part of the pickling barrel 1 through the water inlet pipe 5 and releases it from the water outlet pipe 4. It flows in the lower part of the pickling barrel 1, which facilitates the circulation of the brine inside the pickling barrel 1. Continuous circulation helps to quickly transfer the flavor and saltiness of the brine to the surface of the eggshell and the egg white, yolk and other parts inside, shortening the pickling time and improving the overall efficiency.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
