Description

Technical Field

[0001] The invention relates to the technical field of egg pickling, and in particular to an energy-saving egg pickling system and a pickling process. Background Art

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

[0003] When the eggs are first immersed in the marinade, some eggs will float up. As the marinating time goes on, the eggs will slowly sink to the bottom. Since the eggs need to be completely immersed in the marinade, the current practice is to place some plates on the eggs to press the eggs into the marinade. This method may cause hidden cracks on the egg surface, making the eggs more susceptible to contamination.

[0004] During the pickling process, both pickled eggs and pickling liquid may be contaminated by microorganisms, thus causing food safety problems. Therefore, during the pickling process, eggs at different stages need to be regularly sampled and tested for microorganisms to determine whether the pickled eggs meet hygiene standards. This is also to understand the progress of pickling and evaluate whether the speed of the current pickling process meets expectations. However, current pickling equipment requires opening the pickling container during sampling. This process makes it easy for external microorganisms to enter the pickling container, affecting the pickling environment, and also destroying the pressure environment in the pickling container. Moreover, during sampling, only the eggs on the upper layer can be sampled, and it is difficult to sample the eggs on the lower layer. Summary of the invention

[0027] Limiting pieces are fixedly installed in the pickling box, two of the limiting pieces form a group, and a pickled egg rack is placed between a group of limiting pieces.

[0028] An energy-saving egg pickling process, using the energy-saving egg pickling system as described above, comprises the following steps:

[0029] S1: neatly stack the eggs that have been selected, cleaned and disinfected in the egg storage screen of the pickled egg rack. After each egg storage screen is loaded with eggs, the flexible barrier layer above the egg storage screen is opened to cover the egg storage screen;

[0030] S2: placing the pickled egg racks into the pickling box one by one, and placing each pickled egg rack according to the position of the limiting piece;

[0031] S3: The cover plate is sealed and fixed to the pickling box, and then pickling liquid is injected into the pickling box and water is injected 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 a period of pickling, the eggs will gradually sink. After the pressure sensor of the flexible barrier layer can detect that the pressure gradually disappears, the sprocket group will drive the belt chain to drive, and the flexible barrier layer will be stored in the storage slot along with the belt chain.

[0033] S5: After pickling for a period of time, the pickled eggs need to be sampled. The position of the egg sieve is adjusted by the lateral adjustment component and the vertical adjustment component. The egg sieve is adjusted to the bottom of the target egg picking point. The egg sieve intersects with the egg storage sieve from bottom to top to pick up the pickled eggs at the corresponding position. Then, the egg sieve moves to the top of the conveying sieve and intersects with the conveying sieve from top to bottom. The pickled eggs are intercepted in the conveying sieve.

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

[0035] S7: close the gate valve, open the sampling tank, take out the pickled eggs, and test them, and then regularly perform sampling tests on the pickled eggs;

[0036] S8: When the pickling time is over, all the pickled egg racks in the pickling box are taken out, the pickling liquid in the pickling box is drained, and then the water in the hollow interlayer is injected into the pickling box to clean the pickling box.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] 1. Without opening the pickling box, the pickled eggs inside the pickling box can be taken out for random inspection, and when taking out the eggs, pickled eggs at any position can be taken out, which is convenient for people to understand the pickling progress and control the pickling quality without destroying the stability of the internal pickling environment, avoiding environmental damage caused by random inspection and affecting the pickling effect.

[0039] 2. An anti-floating component is set up to prevent the pickled eggs from floating up, ensuring that the pickled eggs are completely immersed in the pickling liquid, making the pickled eggs penetrate more evenly. In addition, the egg storage screen adopts a comb-tooth structure to increase the contact area between the pickled eggs and the pickling liquid, promote uniform penetration of all parts of the pickled eggs, and ensure product quality consistency.

[0040] 3. The temperature and pressure inside the pickling box are controlled, which accelerates the penetration rate of the pickling liquid into the eggs, effectively shortens the pickling time, and improves the 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 following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Reference Figure 1 - Fig.18 An energy-saving egg pickling system and pickling process include a pickling box 100, a cover plate 200, a sampling unit 300 and a pickled egg 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 with the pickling box 100 by bolts. After loosening the bolts, the cover plate 200 can be opened. In addition, a handle is provided on the cover plate 200 for people to open it conveniently.

[0062] A first water inlet pipe 101 and a first drain pipe 102 are arranged outside the pickling box 100 and are connected to the inside of the pickling box 100. Pickling liquid is injected into the pickling box 100 through the first water inlet pipe 101 (the pickling liquid is heated to a suitable temperature and then injected into the pickling box 100). After pickling, the pickling liquid is discharged through the first drain pipe 102. A liquid level sensor is arranged in the pickling box 100 for detecting the water level of the pickling liquid, and a temperature sensor is arranged in the pickling box 100 for detecting the pickling 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 arranged outside 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 and drain water from the hollow interlayer 110. A valve for switching between cooling and heating modes is arranged on the second water inlet pipe 111. 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. The heated water enters the hollow interlayer 110, which can provide a heat preservation effect for the pickling environment inside the pickling box 100 (keep the temperature inside the pickling box 100 constant). The outer wall of the pickling box 100 adopts heat preservation and heat insulation materials to reduce heat dissipation.

[0064] Since an air suction port 220 is arranged on the outside of the cover plate 200 and connected to a pressure control system, the pressure control system includes an air compression pump, a vacuum pump, a pressure gauge and a control valve. The pressure control system can adjust the internal pressure environment of the pickling box 100 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, so after each pickling, the water in the hollow interlayer 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, a plurality of sampling units 300 are arranged in parallel in the pickling box 100, and a pickled egg rack 400 is placed at the position corresponding to each sampling unit 300; the sampling unit 300 includes an egg taking mechanism 310 and a conveying mechanism 320; the egg taking mechanism 310 is composed of a lateral adjustment component 311, a vertical adjustment component 312 and an egg taking screen 313 installed on the lateral adjustment component 311 and the vertical adjustment component 312.

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

[0067] The motor drives the vertical screw rod 3123 to rotate, so that the vertical slider 3122 can move up and down along the vertical screw rod 3123, thereby achieving height adjustment in the vertical direction.

[0068] The transverse adjustment assembly 311 includes a transverse slide bar 3111, a transverse slider 3112 and a transverse screw rod 3113. The two ends of the transverse slide bar 3111 are fixed on two vertical sliders 3122. The two ends of the transverse screw rod 3113 are rotatably mounted on the two vertical sliders 3122. The transverse screw rod 3113 is driven by a motor. The transverse slide bar 3111 is installed in parallel with the transverse screw rod 3113. The transverse slider 3112 is slidably mounted on the transverse slide bar 3111. The transverse slider 3112 is connected to the transverse screw rod 313 by threads.

[0069] Since the transverse adjustment component 311 is installed on the vertical adjustment component 312, when the vertical slider 3122 moves up and down along the vertical screw rod 3123, the transverse adjustment component 311 will move up and down as a whole. By driving the rotation, the transverse slider 3112 can move left and right along the transverse screw rod 313, thereby realizing position adjustment in the horizontal direction.

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

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

[0072] The area between each salted egg layer and the upper and lower adjacent salted egg layers is the transverse walking area a, and the side panel 410 is provided with a transverse opening 411 at a position corresponding to 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 pickled egg rack 400 is the vertical walking area b. Because the egg taking screen 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 taking screen 313.

[0074] When the present application performs random inspection on pickled eggs, the egg taking mechanism 310 takes the eggs by scooping them up. Since the eggs are fragile and soaked in pickling liquid, it is not suitable to adopt common methods of taking eggs such as clamping or sucking. The following will combine the structural characteristics of the pickled egg rack 400 and the egg taking mechanism 310 to describe in detail the process of taking eggs by the egg taking screen 313:

[0075] First, a sampling inspection position is selected (a monitoring camera can be installed on the inner wall of the pickling box 100 or the cover plate 200 to facilitate viewing of the internal situation of the pickling box 100). After determining that the pickled eggs in a certain position of a certain pickled egg layer of the pickled egg rack 400 are to be sampled, the height of the egg sieve 313 is adjusted by the vertical adjustment component 312 (the egg sieve is initially located at the vertical walking area b, such as Fig.11 As shown in the figure, the egg taking sieve 313 is adjusted to be located below the target pickled egg layer, and then the egg taking sieve 313 is allowed to enter the lateral walking area a through the lateral opening 411, and then the position of the egg taking sieve 313 is adjusted left and right through the lateral adjustment component 311, so that the egg taking sieve 313 reaches directly below the target egg taking point, and then the egg taking sieve is controlled to move from bottom to top through the vertical adjustment component 312, so that the egg taking sieve 313 and the egg storage sieve 420 are staggered. Since the egg taking sieve 313 and the egg storage sieve 420 are both comb-tooth-shaped, and the egg taking sieve 313 moves from bottom to top, at the moment of staggering, the egg taking sieve 313 will pick up the pickled eggs at the corresponding position of the egg storage sieve 420 (here the egg taking sieve 313 must move from bottom to top to take out the pickled eggs);

[0076] Afterwards, the egg sieve 313 moves horizontally in the horizontal walking area a, returns to the vertical walking area b through the horizontal opening 411, and then moves upward along the vertical walking area b until it reaches the position of the conveying mechanism 320 (the path diagram of the egg sieve 313 taking eggs during the process is as shown in FIG. Fig.18 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 taking screen 313 and the conveying screen 321 of each sampling unit 300 are located in the same plane with the corresponding pickled egg rack 400.

[0078] The end of the conveying screen 321 close to the conveying trough 322 is the end, and the end away from the conveying trough 322 is the head end. The head end of the conveying screen 321 is fixedly installed with the side plate 3131, and the end is open design; after the egg sieve 313 takes eggs from the pickled egg rack 400, the eggs will be put into the conveying screen 321. The conveying screen 321 is also comb-shaped. The egg sieve 313 passes through the conveying screen 321 from top to bottom. In the process of the two interlacing, the eggs will be intercepted by the conveying screen 321 and transferred from the egg sieve 313 to the conveying screen 321.

[0079] The end of the conveying screen 321 is rotatably mounted on the pickling box 100, the head end of the conveying screen 321 is rotatably connected to the top of the telescopic rod 3211, the bottom of the telescopic rod 3211 is fixedly mounted on the inner wall of the pickling box 100, and the telescopic rod 3211 is an electrically controlled telescopic rod;

[0080] When the telescopic rod 3211 is in a retracted state, the conveying screen 321 is in a horizontal state. When the telescopic rod 321 is in an extended state, the conveying screen 321 will tilt toward the end, and when the conveying screen 321 is in an inclined state, the end of the conveying screen 321 is connected to the inner diameter head end of the conveying trough 322. At this time, the eggs in the conveying screen 321 will roll along the conveying screen 321 into the conveying trough 322.

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

[0082] The eggs rolled 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 provided on the side wall of the pickling 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 head end of the conveying pipe 323 is connected to the conveying trough 322, and the tail end is connected to the sampling tank 324.

[0083] When the gate valve 3231 is opened, the delivery pipe 323 connects the delivery trough 322 and the sampling tank 324. When the gate valve 3231 is closed, the communication channel among the delivery trough 322, the delivery pipe 323 and the sampling tank 324 will be cut off. Since the delivery trough 322 is located inside the pickling box 100 and the sampling tank 324 is located outside the pickling box 100, when the gate valve 3231 is closed, the pickling box 100 is in an independent sealed state. When the gate valve 3231 is opened, the pickling box 100 is connected to the sampling tank 324.

[0084] When sampling eggs, it is necessary to open the gate valve 3231. After the pickled eggs enter the conveying pipe 323, since the gate valve 3231 is opened, the pickled eggs will directly roll into the sampling tank 324 along the conveying pipe 323. An interception net 3242 is arranged inside the sampling tank 324. Therefore, the pickled eggs will eventually fall on the interception net 3242.

[0085] A top cover 3241 is provided on the top of the sampling tank 324, and the top cover 3241 is sealed and fixed to the sampling tank 324 by bolts. During the entire process of pickling and egg taking, the top cover 3241 is in a sealed state. After the egg taking is completed, the gate valve 3231 is closed to cut off the communication channel between the pickling box 100 and the sampling tank 324, and 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 provided at the bottom of the sampling tank 324 to connect to the first drain pipe 102, which is convenient for subsequent cleaning and drainage.

[0086] The following will describe in detail the process of the egg sieve 313 putting the pickled eggs into the conveying mechanism 320 and the conveying mechanism 320 conveying the pickled eggs to the outside of the pickling box 100 in combination with the structural features of the egg sieve 313 and the conveying mechanism 320:

[0087] First, after the egg taking sieve 313 has taken the eggs, the egg taking sieve 313 is moved to just above the conveying sieve 321 (the position of the conveying sieve 321 can be set above the liquid surface of the pickling liquid) by the lateral adjustment component 311 and the vertical adjustment component 312, and then the egg taking sieve 313 is moved downward and interlaced with the conveying sieve 321. When interlacing, the comb teeth of the egg taking sieve 313 and the conveying sieve 321 are interlaced with each other, and the pickled eggs are intercepted by the conveying sieve 321 and transferred from the egg taking sieve 313 to the conveying sieve 321. Then, the egg taking sieve 313 continues to move to the vertical walking area b, returns to the initial state, and waits for the next egg taking operation;

[0088] After the pickled eggs are transferred to the conveying screen 321, the conveying screen 321 is tilted (the conveying 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 and there is a risk of cracking), and the pickled eggs roll along the conveying screen 321, the conveying trough 322, and the conveying pipe 323, and finally fall into the interception net 3242 of the sampling tank 324.

[0089] Some eggs that have been stored for a long time have an enlarged internal air chamber, which causes them to float on the surface of the pickling liquid during pickling. This will lead to uneven pickling and extend the pickling time. The part of the pickled egg that is in contact with the pickling liquid and the exposed part will also form a clear dividing line, affecting the overall appearance of the pickled egg. Therefore, the present application installs an anti-floating component 430 above each pickled egg layer.

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

[0091] A flexible barrier layer 431 (the flexible barrier layer 431 may be a thin piece of cloth or a net) is installed between the two belt chains 432 on both sides of the pickled egg layer. The flexible barrier layer 431 covers the egg storage screen 420 to prevent the eggs in the egg storage screen 420 from floating up. The two ends of the flexible barrier layer 431 are respectively fixed to the two belt chains, and a pressure sensor is provided at the connection between the flexible barrier layer 431 and the belt chain. The floating of the eggs will pull the flexible barrier layer 431, so the pressure sensor will detect a force (many existing pressure sensors are tensile pressure sensors, which can detect both pressure and tension), which means that the eggs in the egg storage screen 420 have sunk, and the flexible barrier layer 431 can be retracted at this time.

[0092] The egg storage screen 420 of each pickled egg layer is provided with a receiving groove 421 which crosses the egg storage screen 420. Both ends of the receiving groove 421 are connected to the mounting groove 4110. The receiving groove 421 is used to receive the flexible barrier layer 431. At the beginning of pickling, the flexible barrier layer 431 needs to be covered on the egg storage screen 420. At this time, the flexible barrier layer 431 is in a horizontal state (such as Figure 6 As shown in FIG. 4 ), when the pressure sensor detects no force, the sprocket set 433 is rotated to gradually change the flexible barrier layer 431 from a horizontal state to a vertical state and enter the receiving groove 421 (as shown in FIG. 4 ). Figure 7 The principle is as follows:

[0093] The sprocket set 433 rotates to drive the belt chain 432, and the belt chain 432 originally located above the egg storage screen 420 is transmitted to the installation groove 4110, and 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 are moved into the installation groove 4110. At the same time, the flexible barrier layer 431 is located in the storage groove 421 as a whole.

[0094] The egg-taking operation can only be performed after the flexible barrier layer 431 is put into the storage groove 421. It should be noted that some pickled eggs float up at the beginning, and after being soaked in the pickling liquid for a while, they will be in a suspended state. Then, as the pickling time goes by, they will gradually sink. When the pickled eggs are in a suspended state, the flexible barrier layer 431 will not be pulled. Therefore, the flexible barrier layer 431 can be put away at this time.

[0095] like Figure 3As shown, a limiter 120 is fixedly installed in the pickling box 100, and two limiters 120 form a group. A pickled egg rack 400 is placed between a group of limiters 120. The limiter 120 is fixed in the pickling box 100, and the egg taking mechanism 310 and the conveying mechanism 320 are also fixed in the pickling box 100. The pickled egg rack 400 can be taken out of the pickling box 100. Each time pickling is performed, the pickled egg rack 400 needs to be put back into the pickling box 100. Since the position where the pickled egg rack 400 is placed is associated with the egg taking mechanism 310 and the conveying mechanism 320, the installation position of the pickled egg rack 400 is specified. The limiter 120 is provided to facilitate the pickled egg rack 400 to be quickly and accurately placed in the specified position each time the pickled egg rack 400 is placed.

[0096] An energy-saving egg pickling process, using the energy-saving egg pickling system, comprises the following steps:

[0097] S1: neatly stack the eggs that have been selected, cleaned and disinfected in the egg storage screen 420 of the pickled egg rack 400. After each egg storage screen 420 is loaded with eggs, the flexible barrier layer 431 above the egg storage screen 420 is opened to cover the egg storage screen 420;

[0098] S2: placing the pickled egg racks 400 into the pickling box 100 one by one, and placing each pickled egg rack 400 according to the position of the limiting member 120;

[0099] S3: The cover plate 200 is sealed and fixed to the pickling box 100, and then the pickling liquid is injected into the pickling box 100, and water is injected into the hollow interlayer 110, and then the air pressure in the pickling box 100 is adjusted by 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 a period of pickling, the eggs will gradually sink. After the pressure sensor of the flexible barrier layer 431 detects that the pressure gradually disappears, the sprocket set 433 will drive the belt chain 432 to drive, and the flexible barrier layer 431 is driven by the belt chain 432 and stored in the storage groove 421;

[0101] S5: After pickling for a period of time, the pickled eggs need to be sampled. The position of the egg taking screen 313 is adjusted by the lateral adjustment component 311 and the vertical adjustment component 312. The egg taking screen 313 is adjusted to the bottom of the target egg taking point. The egg taking screen 313 intersects with the egg storage screen 420 from bottom to top to pick up the pickled eggs at the corresponding position. Then, the egg taking screen 313 moves to the top of the conveying screen 321, and then intersects with the conveying screen 321 from top to bottom. The pickled eggs are trapped in the conveying screen 321;

[0102] S6: Open the gate valve 3231, and then control the conveying screen 321 to tilt, so that the pickled eggs pass through the conveying screen 321, the conveying trough 322, and the conveying pipe 323 in sequence and fall into the sampling tank 324, and are caught by the interception net 3242 in the sampling tank 324;

[0103] S7: Close the gate valve 3231, open the sampling tank 324, take out the pickled eggs, and test them, and then regularly sample the pickled eggs;

[0104] S8: When the pickling time is over, all the pickled egg racks 400 in the pickling box 100 are taken out, the pickling liquid in the pickling box 100 is drained, and then the water in the hollow interlayer 110 is injected into the pickling box 100 to clean the pickling box 100.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
