Description

Technical Field

[0001] This invention relates to the field of egg curing technology, and in particular to an energy-saving egg curing system and curing process. Background Technology

[0002] There are three main methods for pickling eggs: water pickling, salt coating, and mud coating. Water pickling is usually used when pickling eggs in batches. In order to shorten the pickling time and improve production efficiency, the pickling temperature and the pressure inside the pickling container are usually controlled during the pickling process. The pickling process is as follows: After the eggs are pre-treated, they are placed in the pickling container, the pickling liquid is injected, and then a certain pressure is applied to the container through the pressure control system to create a pressure difference between the inside and outside of the eggs. At the same time, the pickling temperature is controlled at 30-35℃. This pickling environment can accelerate the penetration of the pickling liquid into the eggs and shorten the pickling time.

[0003] When eggs are first immersed in the marinade, some will float. As the marinating time progresses, the eggs will slowly sink to the bottom. Since the marinating process requires the eggs to be completely submerged in the marinade, the current practice is to place some boards on top of the eggs to press them into the marinade. This method may cause microcracks on the surface of the eggs, making them more susceptible to contamination.

[0004] Because both the pickled eggs and the pickling liquid can be contaminated by microorganisms during the pickling process, potentially leading to food safety issues, it is necessary to regularly sample eggs at different stages of the pickling process for microbial testing to determine whether the pickled eggs meet hygiene standards. This also helps to understand the pickling progress and assess whether the current pickling process is meeting expectations. However, current pickling equipment requires opening the pickling container for sampling, which can easily allow external microorganisms to enter the container, affecting the pickling environment and disrupting the pressure environment inside. Furthermore, sampling often only allows for sampling the eggs on the top layer, making it difficult to sample the eggs on the bottom layer. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art by proposing an energy-saving egg pickling system and pickling process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An energy-saving egg pickling system and pickling process includes: a pickling box, a cover plate, a sampling unit, and an egg pickling rack. The cover plate is sealed to the pickling box. Multiple sampling units are arranged in parallel inside the pickling box, and an egg pickling rack is placed at the location of each sampling unit.

[0008] The sampling unit includes an egg-collecting mechanism and a conveying mechanism; the egg-collecting mechanism consists of a horizontal adjustment component, a vertical adjustment component, and an egg-collecting sieve installed on the horizontal adjustment component and the vertical adjustment component, wherein the bottom of the egg-collecting sieve is comb-shaped and the sides are side plates;

[0009] The conveying mechanism includes a conveying screen, a conveying trough, a conveying pipe, and a sampling tank. The conveying screen, conveying trough, conveying pipe, and sampling tank are installed on the pickling box from left to right and are interconnected with each other. The bottom of the conveying screen is comb-shaped.

[0010] The egg pickling rack includes two side panels, multiple egg storage sieves, and an anti-floating component. The egg pickling rack is designed as a multi-layer structure, and each layer consists of two side panels and an independent egg storage sieve. An anti-floating component is installed above each egg pickling layer, and the bottom of the egg storage sieve is comb-shaped.

[0011] As a further aspect of the present invention: the area between the pickled egg layer and the adjacent pickled egg layers is a transverse walking area, and the side plate has a transverse opening at the corresponding position of the transverse walking area. The height of the transverse walking area and the transverse opening is greater than the height of the egg sieve.

[0012] The area between the conveying mechanism and the egg pickling rack is a vertical walking area, and the width of the vertical walking area is greater than the width of the egg scooping sieve.

[0013] The egg-collecting sieve, conveying sieve, and corresponding pickling rack of each sampling unit are located on the same plane.

[0014] As a further embodiment of the present invention: the anti-floating component includes a flexible barrier layer, a belt chain and a sprocket assembly. Each pickled egg layer has a mounting groove at the transverse opening position on its left and right sides. The sprocket assembly is installed in the mounting groove. The belt chain is wound around the sprocket assembly and is tensioned. The sprocket assembly is driven by a motor.

[0015] A flexible barrier layer is installed between two belt chains on both sides of the egg pickling layer. The flexible barrier layer covers the egg storage sieve and its two ends are fixed to the two belt chains respectively. A pressure sensor is installed on the flexible barrier layer.

[0016] Each layer of pickled eggs has an egg storage sieve with a storage groove running through it. The two ends of the storage groove are connected to the mounting groove. The storage groove is used to store the flexible barrier layer.

[0017] As a further aspect of the present invention: the vertical adjustment component includes a vertical slide rail, a vertical slider, and a vertical lead screw. Two vertical slide rails are provided and are respectively fixedly installed on the left and right inner walls of the pickling box. Vertical sliders are slidably installed on both vertical slide rails, and one of the vertical sliders is connected to the vertical lead screw by a thread. The vertical lead screw is parallel to the vertical slide rail, and both ends of the vertical lead screw are rotatably connected to the pickling box. The vertical lead screw is driven by a motor.

[0018] The horizontal adjustment assembly includes a horizontal slide bar, a horizontal slider, and a horizontal lead screw. The two ends of the horizontal slide bar are fixed to two vertical sliders, and the two ends of the horizontal lead screw are rotatably mounted on two vertical sliders. The horizontal lead screw is driven by a motor, and the horizontal slide bar and the horizontal lead screw are installed parallel to each other. The horizontal slider is slidably mounted to the horizontal slide bar and is connected to the horizontal lead screw by a thread. The egg sieve is fixedly mounted on the horizontal slider.

[0019] As a further embodiment of the present invention: a conveying port is opened on the side wall of the pickling box, the conveying pipe is fixedly installed in the conveying port, a gate valve is installed on the conveying pipe, and the first end of the conveying pipe is connected to the conveying trough and the last end is connected to the sampling tank.

[0020] The sampling tank is equipped with a top cover, which is sealed and fixed to the sampling tank with bolts. An interception net is arranged inside the sampling tank.

[0021] The conveying trough is fixedly installed on the inner side wall of the pickling box. The conveying trough is inclined and its inner diameter gradually decreases from the first end to the last end. The first end of the inner diameter of the conveying trough is connected to the last end of the conveying screen, and the last end of the inner diameter of the conveying trough is connected to the first end of the conveying pipe.

[0022] As a further embodiment of the present invention: the end of the conveying screen closest to the conveying trough is the end end, and the end furthest from the conveying trough is the beginning end. The beginning end of the conveying screen is fixedly installed with a side plate, and the end end is an open design.

[0023] The end of the conveyor screen is rotatably installed with the marinating box, the beginning of the conveyor screen is rotatably connected with the top of the telescopic rod, and the bottom of the telescopic rod is fixedly installed on the inner wall of the marinating box.

[0024] When the telescopic rod is in the retracted state, the conveying screen is horizontal; when the telescopic rod is in the extended state, the conveying screen is tilted, and when the conveying screen is tilted, the end of the conveying screen is connected to the beginning of the channel of the conveying trough.

[0025] As a further aspect of the present invention: a first water inlet pipe and a first drain pipe are provided on the outside of the pickling box and communicate with the inside of the pickling box; a hollow interlayer for storing water is provided on the wall of the pickling box; a second water inlet pipe and a second drain pipe are provided on the outside of the pickling box and communicate with the hollow interlayer; and the second drain pipe is communicated with the pickling box; a temperature sensor and a liquid level sensor are provided inside the pickling box.

[0026] As a further embodiment of the present invention: the cover plate is rotatably connected to the marinating box, and the four corners of the cover plate are sealed to the marinating box by bolts. An air extraction port is provided on the outside of the cover plate to connect to the pressure control system. At the same time, a cleaning nozzle is installed inside the cover plate, and the cleaning nozzle is connected to the second drain pipe.

[0027] The pickling box is fixedly installed with limiting components, and two limiting components are placed as a group, with a pickling rack placed between the groups of limiting components.

[0028] An energy-saving egg curing process, using the energy-saving egg curing system described above, includes the following steps:

[0029] S1: After the eggs have been selected, cleaned and disinfected, they are neatly arranged in the egg storage sieve of the egg pickling rack. After each egg storage sieve is filled with eggs, the flexible barrier layer above the egg storage sieve is opened and covered on the egg storage sieve.

[0030] S2: Place the egg pickling racks into the pickling box one by one, with each rack positioned according to the location of the limiting piece;

[0031] S3: Seal and fix the cover plate to the pickling box, then inject pickling liquid into the pickling box and inject water into the hollow interlayer;

[0032] S4: In the initial stage of pickling, some eggs will float up, so the pressure sensor of the flexible barrier layer can detect the pressure. After pickling for a period of time, the eggs will gradually sink. After the pressure sensor of the flexible barrier layer can detect that the pressure is gradually disappearing, the sprocket assembly will drive the belt chain transmission, and the flexible barrier layer will be driven by the belt chain transmission and enter the storage tank.

[0033] S5: After pickling for a period of time, the pickled eggs need to be sampled. The position of the egg-collecting sieve is adjusted by the horizontal adjustment component and the vertical adjustment component. The egg-collecting sieve is adjusted to be below the target egg-collecting point. The egg-collecting sieve passes through the egg-storage sieve from bottom to top and picks up the pickled eggs at the corresponding position. Then the egg-collecting sieve moves to the top of the conveyor sieve and passes through the conveyor sieve from top to bottom. The pickled eggs are trapped in the conveyor sieve.

[0034] S6: Open the gate valve, then control the conveyor screen to tilt. The pickled eggs pass through the conveyor screen, conveyor trough, and conveyor pipe in sequence and fall into the sampling tank, where they are caught by the interception net inside the sampling tank.

[0035] S7: Close the gate valve, open the sampling tank, take out the pickled eggs, and test them. Then, conduct regular sampling tests on the pickled eggs.

[0036] S8: When the marinating time is over, remove all the egg racks from the marinating box, drain the marinating liquid from the marinating box, and then inject water from the hollow jacket into the marinating box to clean it.

[0037] Compared with existing technologies, the advantages of this invention are:

[0038] 1. Without opening the pickling box, the pickled eggs inside can be sampled and inspected. When taking eggs, pickled eggs can be taken from any position, which makes it convenient for people to understand the pickling progress and control the pickling quality. This will not disrupt the stability of the internal pickling environment and avoid the pickling effect being affected by environmental damage caused by sampling.

[0039] 2. The anti-floating component prevents the pickled eggs from floating, ensuring that the eggs are completely submerged in the pickling solution and allowing for more even penetration. In addition, the egg storage sieve has a comb-like structure, which increases the contact area between the pickled eggs and the pickling solution, promotes even penetration of all parts of the eggs, and ensures consistent product quality.

[0040] 3. The temperature and pressure control inside the pickling box accelerates the penetration of the pickling liquid into the eggs, effectively shortens the pickling time, and improves pickling efficiency. In addition, the water used for temperature control in this application can be used to clean the pickling box after each pickling, which is in line with the concept of energy conservation and environmental protection, reduces production costs and resource consumption, and enhances the sustainability and economy of the process.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Reference Figure 1 - Figure 18 An energy-saving egg pickling system and pickling process are disclosed, including a pickling box 100, a cover plate 200, a sampling unit 300 and an egg pickling rack 400. The cover plate 200 is rotatably connected to the pickling box 100, and the four corners of the cover plate 200 are sealed to the pickling box 100 by bolts. The cover plate 200 can be opened after the bolts are loosened. In addition, the cover plate 200 is provided with handles for easy opening.

[0062] The marinating box 100 is externally equipped with a first water inlet pipe 101 and a first drain pipe 102, which are connected to the inside of the marinating box 100. The marinating liquid is injected into the marinating box 100 through the first water inlet pipe 101 (the marinating liquid is heated to a suitable temperature before being injected into the marinating box 100). After marinating, the marinating liquid is discharged through the first drain pipe 102. The marinating box 100 is equipped with a liquid level sensor to detect the water level of the marinating liquid and a temperature sensor to detect the marinating temperature.

[0063] The wall of the pickling box 100 is provided with a hollow interlayer 110 for storing water. A second water inlet pipe 111 and a second drain pipe 112 are provided on the outside of the pickling box 100 and are connected to the hollow interlayer 110. The second water inlet pipe 111 and the second drain pipe 112 are used to inject water into the hollow interlayer 110 and drain water out. A valve is provided on the second water inlet pipe 111 for switching between cooling and heating modes. The valve is connected to a water source heat pump unit. The water source heat pump unit is used to heat (or cool) the water. After being heated, the water enters the hollow interlayer 110, which can provide a heat preservation effect for the pickling environment inside the pickling box 100 (keeping the temperature inside the pickling box 100 constant). The outer wall of the pickling box 100 is made of heat insulation material to reduce heat loss.

[0064] Because the cover plate 200 is equipped with an air extraction port 220 connected to a pressure control system, which includes an air compressor pump, a vacuum pump, a pressure gauge and a control valve, the pressure environment inside the pickling box 100 can be adjusted through the pressure control system to improve the penetration speed and effect of the pickling liquid. In addition, a cleaning nozzle 210 is installed inside the cover plate 200; the second drain pipe 112 is connected to the cleaning nozzle 210. Therefore, after each pickling, the water in the hollow jacket 110 can be injected into the pickling box 100 through the cleaning nozzle 210 to rinse the pickling box 100.

[0065] like Figure 2 As shown, multiple sampling units 300 are arranged in parallel inside the pickling box 100, and each sampling unit 300 is positioned to correspond to a pickling rack 400. The sampling unit 300 includes an egg-retrieving mechanism 310 and a conveying mechanism 320. The egg-retrieving mechanism 310 consists of a horizontal adjustment component 311, a vertical adjustment component 312, and an egg-retrieving sieve 313 installed on the horizontal adjustment component 311 and the vertical adjustment component 312.

[0066] Both the horizontal adjustment component 311 and the vertical adjustment component 312 are screw adjustment mechanisms (the principle is similar to that of a screw jack). The vertical adjustment component 312 includes a vertical slide rail 3121, a vertical slider 3122, and a vertical screw 3123. Two vertical slide rails 3121 are provided and are fixedly installed on the left and right inner walls of the marinating box 100, respectively. The vertical slider 3122 is slidably installed on both vertical slide rails 3121, and one of the vertical sliders 3122 is connected to the vertical screw 3123 by a thread. The vertical screw 3123 is parallel to the vertical slide rail 3121, and both ends of the vertical screw 3123 are rotatably connected to the marinating box 100. The vertical screw 3123 is driven by a motor.

[0067] The motor drives the vertical lead screw 3123 to rotate, which allows the vertical slider 3122 to move up and down along the vertical lead screw 3123, thereby achieving height adjustment in the vertical direction.

[0068] The lateral adjustment assembly 311 includes a lateral slide bar 3111, a lateral slider 3112, and a lateral lead screw 3113. The two ends of the lateral slide bar 3111 are fixed to two vertical sliders 3122. The two ends of the lateral lead screw 3113 are rotatably mounted on two vertical sliders 3122. The lateral lead screw 3113 is driven by a motor. The lateral slide bar 3111 and the lateral lead screw 3113 are installed in parallel. The lateral slider 3112 is slidably mounted to the lateral slide bar 3111. The lateral slider 3112 and the lateral lead screw 3113 are connected by threads.

[0069] Since the horizontal adjustment component 311 is mounted on the vertical adjustment component 312, when the vertical slider 3122 moves up and down along the vertical lead screw 3123, the horizontal adjustment component 311 will move up and down as a whole. By driving the rotation, the horizontal slider 3112 can move left and right along the horizontal lead screw 3113, thereby realizing position adjustment in the horizontal direction.

[0070] The egg sieve 313 is fixedly installed on the horizontal slider 3112. The bottom of the egg sieve 313 is comb-shaped, and the two sides are side plates 3131. The egg sieve 313 can be moved up and down and left and right in the plane by the horizontal adjustment component 311 and the vertical adjustment component 312.

[0071] like Figure 5-10 As shown, the egg pickling rack 400 includes two side plates 410, multiple egg storage sieves 420, and multiple anti-floating components 430. The egg pickling rack 400 is designed as a multi-layer structure, and each layer consists of two side plates 410 and an independent egg storage sieve 420. The egg storage sieve 420 of each egg pickling layer is used to place eggs. Since the bottom of the egg storage sieve 420 is comb-shaped, the contact area between the pickled eggs and the pickling liquid is increased.

[0072] The area between each layer of pickled eggs and the adjacent layers above and below is a transverse walking area a. The side plate 410 has a transverse opening 411 at the corresponding position of the transverse walking area a. Because the egg sieve 313 needs to move laterally in the transverse walking area a, the height of the transverse walking area a and the transverse opening 411 is greater than the height of the egg sieve 313.

[0073] The area between the conveying mechanism 320 and the egg pickling rack 400 is the vertical walking area b. Because the egg sieve 313 needs to move vertically in the vertical walking area b, the width of the vertical walking area b is greater than the width of the egg sieve 313.

[0074] When conducting random inspections of pickled eggs in this application, the egg-retrieving mechanism 310 retrieves the eggs by scooping them up. Because the eggs are fragile and immersed in the pickling solution, common methods of tweezing or sucking are not suitable. The following will describe in detail the egg-retrieving process of the egg-retrieving sieve 313, taking into account the structural characteristics of the pickling rack 400 and the egg-retrieving mechanism 310:

[0075] First, the sampling location must be selected (a monitoring camera can be installed on the inner wall of the pickling box 100 or the cover plate 200 to facilitate viewing the internal situation of the pickling box 100). After determining the location of the pickled eggs in a specific layer of the pickling rack 400 to be sampled, the height of the egg-collecting sieve 313 is adjusted using the vertical adjustment component 312 (the egg-collecting sieve is initially located at the vertical walking area b, such as...). Figure 11 As shown), adjust the egg-retrieving sieve 313 to be below the target pickled egg layer, then let the egg-retrieving sieve 313 enter the horizontal walking area a through the horizontal opening 411. Then, adjust the position of the egg-retrieving sieve 313 left and right through the horizontal adjustment component 311 so that the egg-retrieving sieve 313 reaches directly below the target egg-retrieving point. Then, control the egg-retrieving sieve to move from bottom to top through the vertical adjustment component 312 so that the egg-retrieving sieve 313 and the egg-storage sieve 420 cross each other. Since both the egg-retrieving sieve 313 and the egg-storage sieve 420 are comb-shaped and the egg-retrieving sieve 313 moves from bottom to top, at the moment of crossing, the egg-retrieving sieve 313 will pick up the pickled egg at the corresponding position of the egg-storage sieve 420 (here the egg-retrieving sieve 313 must move from bottom to top in order to pick up the pickled egg).

[0076] Then, the egg-collecting sieve 313 moves laterally in the horizontal travel zone a, returns to the vertical travel zone b through the horizontal opening 411, and then moves upward along the vertical travel zone b until it reaches the position of the conveyor mechanism 320 (the path diagram of the egg-collecting process of the egg-collecting sieve 313 is shown below). Figure 18 (As shown).

[0077] like Figure 13-16 As shown, the conveying mechanism 320 includes a conveying screen 321, a conveying trough 322, a conveying pipe 323, and a sampling tank 324. The egg-collecting screen 313, the conveying screen 321, and the corresponding egg-marinating rack 400 of each sampling unit 300 are located in the same plane.

[0078] The end of the conveyor sieve 321 closest to the conveyor trough 322 is the end, and the end furthest from the conveyor trough 322 is the beginning. The beginning of the conveyor sieve 321 is fixedly installed with a side plate 3131, and the end is an open design. After the egg-retrieving sieve 313 takes the egg from the egg pickling rack 400, it will put the egg into the conveyor sieve 321. The conveyor sieve 321 is also comb-shaped. The egg-retrieving sieve 313 passes over the conveyor sieve 321 from top to bottom. During the process of the two passing each other, the egg will be intercepted by the conveyor sieve 321 and transferred from the egg-retrieving sieve 313 to the conveyor sieve 321.

[0079] The end of the conveyor screen 321 is rotatably installed with the marinating box 100, the beginning of the conveyor screen 321 is rotatably connected with the top of the telescopic rod 3211, the bottom of the telescopic rod 3211 is fixedly installed on the inner wall of the marinating box 100, and the telescopic rod 3211 is an electrically controlled telescopic rod.

[0080] When the telescopic rod 3211 is in the retracted state, the conveyor screen 321 is in a horizontal state. When the telescopic rod 3211 is in the extended state, the conveyor screen 321 will tilt towards the end. When the conveyor screen 321 is in the tilted state, the end of the conveyor screen 321 is connected to the inner diameter of the conveyor trough 322. At this time, the eggs in the conveyor screen 321 will roll along the conveyor screen 321 into the conveyor trough 322.

[0081] The conveying trough 322 is fixedly installed on the inner wall of the pickling box 100. The conveying trough 322 is a semi-cylindrical shell shape and is inclined. The inner diameter of the conveying trough 322 gradually decreases from the first end to the last end. At the same time, the first end of the inner diameter of the conveying trough 322 is connected to the last end of the conveying screen 321, and the last end of the inner diameter of the conveying trough 322 is connected to the first end of the conveying pipe 323.

[0082] Eggs that roll into the conveying trough 322 will roll along the inner radial conveying pipe 323 of the conveying trough 322 until they enter the conveying pipe 323. A conveying port 130 is opened on the side wall of the marinating box 100. The conveying pipe 323 is fixedly installed in the conveying port 130. A gate valve 3231 is installed on the conveying pipe 323. The first end of the conveying pipe 323 is connected to the conveying trough 322, and the last end is connected to the sampling tank 324.

[0083] When the gate valve 3231 is open, the conveying pipe 323 connects the conveying trough 322 and the sampling tank 324. When the gate valve 3231 is closed, it cuts off the connection between the conveying trough 322, the conveying pipe 323, and the sampling tank 324. Since the conveying trough 322 is located inside the marinating box 100 and the sampling tank 324 is located outside the marinating box 100, the marinating box 100 is in an independent sealed state when the gate valve 3231 is closed, and the marinating box 100 is connected to the sampling tank 324 when the gate valve 3231 is open.

[0084] When sampling eggs, gate valve 3231 needs to be opened. When the pickled eggs enter the conveying pipe 323, the pickled eggs will roll directly into the sampling tank 324 along the conveying pipe 323 due to the opening of gate valve 3231. The sampling tank 324 is equipped with an interception net 3242. Therefore, the pickled eggs will eventually fall on the interception net 3242.

[0085] The sampling tank 324 is equipped with a top cover 3241, which is sealed and fixed to the sampling tank 324 with bolts. The top cover 3241 is in a sealed state throughout the pickling and egg removal process. After the eggs are removed, the gate valve 3231 is closed to cut off the connection between the pickling box 100 and the sampling tank 324. Then the top cover 3241 is opened to take out the pickled eggs in the sampling tank 324 for testing. Since the pickling box 100 and the sampling tank 324 are not connected at this time, opening the top cover 3241 will not affect the internal environment of the pickling box 100. A pipe can be installed at the bottom of the sampling tank 324 to connect to the first drain pipe 102 for subsequent cleaning and drainage.

[0086] The following section will describe in detail the process of the egg-collecting sieve 313 placing the pickled eggs into the conveying mechanism 320 and the conveying mechanism 320 transporting the pickled eggs to the outside of the pickling tank 100, taking into account the structural features of the egg-collecting sieve 313 and the conveying mechanism 320:

[0087] First, after the egg-collecting sieve 313 has collected the eggs, it is moved to a position directly above the conveyor sieve 321 by the horizontal adjustment component 311 and the vertical adjustment component 312 (the position of the conveyor sieve 321 can be set above the surface of the marinating liquid). Then, the egg-collecting sieve 313 moves downward and passes over the conveyor sieve 321. When they pass over each other, the comb teeth of the egg-collecting sieve 313 and the conveyor sieve 321 intersect each other, and the marinated eggs are intercepted by the conveyor sieve 321 and transferred from the egg-collecting sieve 313 to the conveyor sieve 321. After that, the egg-collecting sieve 313 continues to move to the vertical walking area b and returns to the initial state, waiting for the next egg-collecting operation.

[0088] After the pickled eggs are transferred to the conveyor screen 321, the conveyor screen 321 is tilted (the conveyor screen 321 must be tilted after the gate valve 3231 is opened, otherwise the pickled eggs will hit the gate plate of the gate valve 3231, which may cause them to break). The pickled eggs roll along the conveyor screen 321, the conveyor trough 322, and the conveyor pipe 323, and finally fall into the interception net 3242 of the sampling tank 324.

[0089] Some eggs stored for a long time have enlarged internal air cells, causing them to float on the surface of the pickling liquid during pickling. This will result in uneven pickling, prolong the pickling time, and a clear dividing line will form between the part of the pickled egg in contact with the pickling liquid and the exposed part, affecting the overall appearance of the pickled egg. Therefore, this application installs an anti-floating component 430 above each layer of pickled eggs.

[0090] The anti-floating component 430 includes a flexible barrier layer 431, a belt chain 432, and a sprocket assembly 433. Each pickled egg layer has a mounting groove 4110 at the transverse opening 411 on its left and right sides. The sprocket assembly 433 is installed in the mounting groove 4110. The sprocket assembly 433 includes four sprockets arranged in a rectangular shape in the mounting groove 4110. The belt chain 432 is wound around the sprocket assembly 433 and is tensioned. The sprocket assembly 433 is driven by a motor.

[0091] A flexible barrier layer 431 (which can be a thin cloth or mesh) is installed between two belt chains 432 on both sides of the egg-curing layer. The flexible barrier layer 431 covers the egg-collecting sieve 420 to prevent the eggs inside the sieve from floating. Both ends of the flexible barrier layer 431 are fixed to the two belt chains respectively. A pressure sensor is installed at the connection between the flexible barrier layer 431 and the belt chains. When the eggs float, they will pull on the flexible barrier layer 431, so the pressure sensor will detect the force (many existing pressure sensors are tension and pressure sensors, which can detect both pressure and tension). This means that the eggs inside the egg-collecting sieve 420 have sunk, and the flexible barrier layer 431 can be retracted at this time.

[0092] Each egg-collecting sieve 420 of the pickling layer is provided with a storage groove 421 that runs through the egg-collecting sieve 420. The two ends of the storage groove 421 are connected to the mounting groove 4110. The storage groove 421 is used to collect the flexible barrier layer 431. At the beginning of pickling, the flexible barrier layer 431 needs to be covered on the egg-collecting sieve 420. At this time, the flexible barrier layer 431 is in a horizontal state (e.g., Figure 6 As shown), when the pressure sensor cannot detect force, the flexible barrier layer 431 is gradually changed from a horizontal state to a vertical state by rotating the sprocket assembly 433, and then enters the receiving groove 421 (as shown). Figure 7 As shown), its principle is as follows:

[0093] The rotation of the sprocket assembly 433 drives the belt chain 432 to move from the egg storage screen 420 to the mounting groove 4110. The two ends of the flexible barrier layer 431 are fixed to the belt chain 432, so the two ends of the flexible barrier layer 431 move into the mounting groove 4110. At the same time, the entire flexible barrier layer 431 is located in the storage groove 421.

[0094] The egg retrieval operation can only be carried out after the flexible barrier layer 431 is put into the storage tank 421. It should be noted that some pickled eggs will float at first and will be in a suspended state after soaking in the pickling liquid for a while. Then, as the pickling time goes by, they will gradually sink. When the pickled eggs are in a suspended state, they will not pull the flexible barrier layer 431. Therefore, the flexible barrier layer 431 can be put away at this time.

[0095] like Figure 3As shown, limiting members 120 are fixedly installed inside the marinating box 100. Two limiting members 120 form a group, and a pickling rack 400 is placed between a group of limiting members 120. The limiting members 120 are fixed inside the marinating box 100. The egg-retrieving mechanism 310 and the conveying mechanism 320 are also fixed inside the marinating box 100. The pickling rack 400 can be removed from the marinating box 100. Each time the pickling is done, the pickling rack 400 needs to be put back into the marinating box 100. Since the position of the pickling rack 400 is related to the egg-retrieving mechanism 310 and the conveying mechanism 320, the installation position of the pickling rack 400 is specified. The limiting members 120 are set to facilitate the quick and accurate placement of the pickling rack 400 in the specified position each time it is placed.

[0096] An energy-saving egg curing process, using the aforementioned energy-saving egg curing system, includes the following steps:

[0097] S1: After the eggs have been selected, cleaned and disinfected, they are neatly arranged in the egg storage sieve 420 of the egg pickling rack 400. After each egg storage sieve 420 is filled with eggs, the flexible barrier layer 431 above the egg storage sieve 420 is opened and covered on the egg storage sieve 420.

[0098] S2: Place the egg pickling racks 400 into the pickling box 100 one by one, with each egg pickling rack 400 positioned according to the position of the limiting piece 120;

[0099] S3: Seal and fix the cover plate 200 to the marinating box 100, then inject the marinating liquid into the marinating box 100 and inject water into the hollow interlayer 110 at the same time. Then adjust the air pressure inside the marinating box 100 through the pressure control system.

[0100] S4: In the initial stage of pickling, some eggs will float up, so the pressure sensor of the flexible barrier layer 431 can detect the pressure. After pickling for a period of time, the eggs will gradually sink. After the pressure sensor of the flexible barrier layer 431 detects that the pressure gradually disappears, the sprocket assembly 433 will drive the belt chain 432 to drive. The flexible barrier layer 431 will be driven by the belt chain 432 and enter the storage tank 421.

[0101] S5: After pickling for a period of time, the pickled eggs need to be sampled. The position of the egg-collecting sieve 313 is adjusted by the horizontal adjustment component 311 and the vertical adjustment component 312. The egg-collecting sieve 313 is adjusted to reach below the target egg-collecting point. The egg-collecting sieve 313 passes through the egg-storage sieve 420 from bottom to top, and picks up the pickled eggs at the corresponding position. Then the egg-collecting sieve 313 moves to the top of the conveyor sieve 321 and passes through the conveyor sieve 321 from top to bottom. The pickled eggs are trapped in the conveyor sieve 321.

[0102] S6: Open the gate valve 3231, and then control the conveyor screen 321 to tilt. The pickled eggs pass through the conveyor screen 321, the conveyor trough 322, and the conveyor pipe 323 in sequence and fall into the sampling tank 324, where they are caught by the interception net 3242 inside the sampling tank 324.

[0103] S7: Close gate valve 3231, open sampling tank 324, take out pickled eggs, and test them. After that, regularly sample pickled eggs.

[0104] S8: When the marinating time is over, remove all the egg racks 400 from the marinating box 100, drain the marinating liquid from the marinating box 100, and then inject the water from the hollow jacket 110 into the marinating box 100 to clean the marinating box 100.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
