Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing, and in particular relates to a tea egg pre-processing device. Background Art
[0002] The initial processing of tea eggs refers to the process of washing the raw eggs, pre-cooking, cooling and shelling them. (Then the braised eggs are processed.)
[0003] The desired effect is: when the eggs are pre-cooked in the early stage of processing, the egg shells should not be cracked and the egg white should not overflow, and the shells should not be completely broken. When the eggs are finally eaten, the egg shells should be peeled off without sticking.
[0004] Practice has proved that steaming eggs can heat the surface of the eggs evenly, and the probability of cracking the shell and overflowing the egg white is lower than boiling the eggs; breaking the shell completely can completely separate the eggshell membrane from the cooked egg. Utility Model Content
[0005] In view of the above guiding principles, the utility model discloses a tea egg pre-processing device, which consists of three parts: a steaming mechanism, a conveying and cooling mechanism, and a shell crushing mechanism.
[0006] The cooking mechanism is made up of a raw egg feeding compartment at the uppermost stream (hereinafter referred to as the feeding compartment), and the egg steaming compartment and egg boiling compartment that are connected in an inclined manner. It is divided horizontally into multiple guide grooves that can only accommodate a row of eggs. A heating device (gas, electric heating tube, microwave, etc.) is placed under the egg boiling compartment area. The egg steaming compartment and the egg boiling compartment are provided with cover plates, and an air suction hood is provided on the feeding compartment. The downstream end of the cooking mechanism has an upward-curving shape, and the upward curvature is higher than the level of the water in the egg boiling compartment. An egg-moving impeller is provided at the upward-curving portion of the downstream end of the cooking mechanism, and the impeller is axially toothed and extends into the rectangular hole in the middle of the guide groove at the bottom of the downstream end of the cooking mechanism.
[0007] The whole process of pre-cooking eggs is carried out by the eggs sliding down under their own weight. That is, the raw eggs slide from the feeding compartment through the steaming compartment and the boiling compartment under their own weight.
[0008] The steam generated by the egg-boiling compartment directly acts on the egg-steaming compartment and the feeding compartment. The suction hood on the feeding compartment guides the steam to flow mainly to the egg-steaming compartment and the feeding compartment.
[0009] The egg-moving impeller is a controllable driving component that moves the pre-cooked eggs to the conveying and cooling mechanism. At the same time, the blades rotate in the opposite direction to prevent the eggs from sliding out of the steaming mechanism longitudinally.
[0010] The conveying and cooling mechanism is used to cool the pre-cooked eggs by air or water during the transportation to the shell crushing mechanism. The mechanism is composed of a straight chain sprocket with ears and double holes and an egg hanging basket.
[0011] The egg hanging basket has a narrow bottom side in an arc (concave) shape to better hold the eggs. One long side is formed into a tooth shape. The hollowed-out tooth shape can hold the eggs.
[0012] The double-hole straight plate chain sprocket with ears is located at both ends of the egg hanging basket in the length direction, and the double-hole straight plate chain with ears is connected to the shaft holes at both ends of the egg hanging basket in the length direction.
[0013] When the whole processing device is in operation, the chain sprocket drives the egg hanging basket to circulate in the air. During the operation, the pre-cooked eggs can be cooled by air or water.
[0014] The shell crushing mechanism includes a steeply sloped guide plate made of sheet metal and a rotating nail plate. The top end of the steeply sloped guide plate is formed into a toothed ridge. When a hanging basket carrying cooled eggs passes by, the toothed ridge intersects with the hollowed-out portion of the hanging basket, intercepting the eggs and causing them to fall down the slope.
[0015] The rotating nail plate is a hard plate with N diamond-shaped nail tips embedded in a flat surface. The plate rotates around a fixed axis. When an egg falls down a slope, the plate with the N diamond-shaped nail tips rotates to a perpendicular position with the falling egg, causing the two to collide. The diamond-shaped nail tips pierce the eggshell and eggshell membrane, causing the eggshell to break.
[0016] The steep slope guide plate is used to make the falling eggs fall along the steep slope guide plate, and nine out of ten eggs will come into contact and collide with the diamond-shaped nail tips.
[0017] The diamond-shaped nail tip is used not only to pierce the eggshell and eggshell membrane, but also to "tear" the eggshell membrane to facilitate shell breaking and peeling.
[0018] The beneficial effects of the utility model are:
[0019] 1. It realizes the gradual heating process from evenly heated steamed eggs to boiled eggs, reducing the chance of cracked shells and egg white overflowing due to uneven hot and cold effects when raw eggs are directly boiled in water.
[0020] 2. The diamond-shaped nail tip pierces the eggshell and the eggshell membrane, so that the eggshell membrane tightly wrapped in the cooked egg and the cooked egg are connected to the atmosphere, making them breathable and separate, which is more conducive to the complete peeling of the eggshell.

[0029] like Figure 1 As shown, a tea egg pre-processing device includes a steaming mechanism 100, a conveying and cooling mechanism 200 and a shell crushing mechanism 300.
[0030] like Figure 1 、 Figure 2 、 Figure 3 As shown, the cooking mechanism 100 is like a hook Shape. It is made of a sloped integral connection consisting of the upstream feed chamber 101, the steamed egg chamber 102 and the boiled egg chamber 103 that are located downstream. It is divided horizontally into multiple guide grooves that can only allow a row of eggs to slide down. A heating device 105 is placed under the boiled egg chamber 103 area, which can be heated by gas, electric heating tubes, etc. The steamed egg chamber 102 and the boiled egg chamber 103 are provided with a cover plate 106, and the feed chamber 101 is provided with an air suction hood 104. An egg-moving impeller 107 is provided at the upturned part of the downstream end of the steaming and cooking mechanism, and the impeller 107 is axially toothed and extends into the rectangular hole in the middle of the bottom guide groove of the upturned part of the downstream end of the steaming and cooking mechanism. The setting position of the rectangular hole is higher than the water level of the boiled liquid in the boiled egg chamber 102.
[0031] During operation, steam generated by boiling eggs in the egg-boiling chamber 103 directly impacts the egg-steaming chamber 102 and the feed chamber 101. A suction hood 104 on the feed chamber 101 directs the steam primarily toward these two chambers. The weight of the raw eggs, starting in the feed chamber 101, gradually and evenly heats the eggs as they slide toward the egg-steaming chamber 102 and the egg-boiling chamber 103. Once the eggs are pre-cooked, the egg-moving impeller 107 moves them to the hanging basket 201 of the conveyor and cooling mechanism 200.
[0032] like Figure 4 The conveying and cooling mechanism shown is shown in Figure 5 The egg basket 201 is connected to the two ends of the shaft hole and is suspended on the straight chain with ears and double holes. The basket 201 receives the pre-cooked eggs and transfers them to the shell crushing mechanism 300. During the transfer, a fan can be configured in the vertical direction for air cooling, and the egg basket 201 can be sunk in the water tank for water cooling.
[0033] like Figure 5 、 Figure 6 The shell crushing mechanism shown includes a steep slope guide plate 302 and a rotating nail plate 301 made of sheet metal.
[0034] The uppermost end of the steep-slope guide plate is made into a toothed ridge. When the hanging basket 201 carrying the cooled eggs passes by, the toothed ridge intersects with the hollow part of the hanging basket 201. The toothed ridge with a slope intercepts the eggs and rolls down the slope. Then the eggs fall onto the rotating nail plate 301 in the form of free fall.
[0035] The rotating nail plate 301 is a hard plate with N diamond-shaped nail tips embedded in the plane (see Figure 7 ), the flat plate rotates about a fixed axis. When the trapped egg falls down the slope, the plate with N diamond-shaped spikes rotates to a perpendicular position to the falling egg, causing the two to collide, and the diamond-shaped spikes pierce the eggshell and eggshell membrane, causing the shell to break.
[0036] The steep slope guide plate 302 is used to make the falling eggs fall along the steep slope guide plate, and most of them will come into contact and collide with the diamond-shaped nail tips on the rotating nail plate 301.
[0037] like Figure 7 As shown, in order to achieve complete shell crushing and complete separation of the eggshell membrane from the cooked egg, the nail tips on the rotating nail plate 301 are diamond-shaped.
[0038] The operation of the entire processing device is achieved by a chain sprocket and a synchronous pulley, combined with the gear train speed ratio, and a speed-regulating motor.
