Description

Technical Field

[0001] This utility model relates to the technical field of braised egg processing equipment, specifically a machine for boiling and peeling eggs in one piece for processing braised eggs. Background Technology

[0002] In the braised egg processing industry, the traditional production process usually separates the boiling and peeling steps. The boiling stage often uses large pots or steaming equipment. Due to the lack of a proper structure for placing and securing the eggs, they easily collide with each other during boiling, causing shells to crack and egg liquid to leak out. This not only affects the yield of braised eggs but also wastes raw materials. Furthermore, the traditional boiling method results in uneven heating, making it difficult to ensure that each egg is cooked to the same degree, thus affecting the quality of the braised eggs.

[0003] For example, patent application CN202120020986.4 discloses an automatic shelling system for hard-boiled eggs, comprising a first support, a second support, a third support, a centrifugal tumbling mechanism, a lifting mechanism, and a guiding mechanism. The centrifugal tumbling mechanism is connected to the first support, the second support is located at the front of the first support, the lifting mechanism is connected to the second support, the third support is connected to the left side of the second support, and the guiding mechanism is connected to the third support. This automatic shelling system for hard-boiled eggs can uniformly pre-crush the eggshells, significantly improving production efficiency, exhibiting good stability, occupying a relatively small area, and reducing eggshell residue after peeling.

[0004] However, this device is only used for peeling, has a single function, and the egg-boiling and peeling equipment are independent of each other. The connection between the equipment is also inconvenient, resulting in a cumbersome and inefficient production process, which fails to meet the demands of modern braised egg processing enterprises for high-efficiency and high-quality production. Therefore, there is an urgent need to develop a braised egg processing equipment that integrates egg-boiling and peeling functions and possesses efficient, stable, and high-quality processing capabilities.

[0028] like Figure 2As shown, in a preferred embodiment, the steam generating assembly includes a heating box 700 fixed on the base plate 400. Several heating wires 701 are fixedly installed inside the heating box 700, and a steam outlet pipe 704 communicating with the interior of the outer casing 100 is installed on the top of the heating box 700. The steam generating assembly, consisting of the heating box 700 and the heating wires 701, can continuously and stably generate steam, providing a heat source for boiling eggs and ensuring the smooth progress of the egg-boiling process.

[0029] like Figure 2 As shown, in a preferred embodiment, a water supply tank 800 is fixedly installed on both sides of the heating box 700 at the top of the base plate 400. The outer wall of the water supply tank 800 is provided with a transparent glass plate 801, and a water inlet pipe 802 is installed near the top. The water supply tank 800 communicates with the interior of the heating box 700 through the water supply pipe 702 located at the bottom. A sealing valve 703 is installed on the water supply pipe 702.

[0030] like Figure 3 As shown, in a preferred embodiment, a plurality of hydraulic cylinders 102 are fixed on the outer wall of the outer casing 100 on the side away from the outlet 106. Each hydraulic cylinder 102 has a piston rod fixedly connected to a push plate 103, which faces the outlet 106. The hydraulic cylinders 102 and the push plate 103 can accurately push the cooked food to the outlet 106, realizing automatic conveying and improving peeling efficiency.

[0031] like Figure 1 As shown, in a preferred embodiment, the outer casing 100 is provided with a cold water tank 500 on one side of the outlet 106, and a filter screen 600 is fixedly installed inside the cold water tank 500. The cold water tank 500 and the filter screen 600 can quickly cool the shelled parts, and the filter screen 600 separates the broken shells, facilitating subsequent processing and ensuring quality.

[0032] like Figure 4 As shown, in a preferred embodiment, a lifting groove 1051 is provided on each of the outer plates on both the left and right sides of the placement rack 105, and two support plates 1052 are symmetrically fixed to the bottom of the placement rack 105. The lifting groove 1051 facilitates the placement and removal of the placement rack 105, and the support plates 1052 increase the stability of the placement rack 105, making it convenient for placement and transfer.

[0033] When using the integrated egg boiling and peeling machine for processing braised eggs of this utility model:

[0034] Placement: The operator removes the placement rack 105 from the top of the outer casing 100 using the lifting slot 1051, and places it evenly between the upper and lower layers of mesh. The mesh is used for positioning and fixing to prevent collision and damage during subsequent processing. After placement, the placement racks 105 are stacked into the outer casing 100 to make full use of the vertical space inside the outer casing 100 and increase the number of items processed at one time.

[0035] Egg cooking process: The sealing cover 200 on top of the outer casing 100 is closed. The sealing cover 200 and the sealing gasket 104 cooperate to form a good sealing environment, reducing steam leakage and improving cooking efficiency and heat utilization. The steam generating component is activated, and the heating wire 701 in the heating chamber 700 on the bottom plate 400 starts working, heating the water to generate steam. The steam enters the outer casing 100 through the vent pipe 704 at the top of the heating chamber 700 and the bottom of the outer casing 100. The steam diffuses evenly within the casing, completely enveloping the eggs on the rack 105, ensuring even heating and consistent cooking. If the pressure inside the casing becomes too high during the cooking process, the pressure relief valve 203 on top of the sealing cover 200 automatically opens to release excess pressure and ensure safe operation of the equipment.

[0036] Pushing: Once cooked, the hydraulic cylinder 102 on the side of the outer casing 100 away from the outlet 106 is activated. The piston rod of the hydraulic cylinder 102 pushes the push plate 103, precisely pushing the cooked food from the placement rack 105 to the outlet 106 in a horizontal direction.

[0037] Peeling operation: After reaching the discharge port 106, the egg enters between two symmetrically rotating extrusion rollers 107. The rubber layer 1072 on the outer circumference of the extrusion roller 107 has moderate elasticity. During the rotation of the extrusion roller 107, a uniform extrusion force is applied, causing the eggshell to crack. The outer protective layer 1071 acts as a buffer, preventing excessive extrusion force from damaging the egg. Under the continuous action of the extrusion rollers 107, the eggshell is separated from the egg, completing the peeling process.

[0038] Cooling and Cleaning: After peeling, the shells fall from the outlet 106 into the cold water tank 500 on one side of the outer casing 100. The cold water in the cold water tank 500 quickly cools the shells to prevent residual heat from affecting the quality. At the same time, the filter screen 600 inside the cold water tank 500 intercepts and separates any remaining shell fragments from the peeling process, facilitating subsequent cleaning and ensuring cleanliness and quality.

[0039] Moisture replenishment: During the operation of the steam generating component, the water in the heating chamber 700 will be continuously consumed. When the operator observes a low water level through the transparent glass plate 801 on the outer wall of the water replenishment tank 800, the sealing valve 703 on the water replenishment pipe 702 is opened, and the water in the water replenishment tank 800 is automatically replenished into the heating chamber 700 through the water replenishment pipe 702, ensuring that the steam generating component can continuously and stably generate steam and maintain the continuity of the egg-cooking process.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
