Description

Technical Field

[0001] The present application relates to the technical field of salted egg processing, and more specifically, to a salted egg desalting device. Background Art

[0002] Chicken eggs, duck eggs, and other eggs are rich in protein and fat, with the yolk being particularly high in fat. The yolk's main components are 17.5% protein, 32.5% fat, approximately 48% water, and 2% minerals, along with various vitamins. In the yolk, protein acts as an emulsifier, dissolving the fat in the water and giving the yolk a uniform, gelatinous consistency.

[0003] During the salting process, a large amount of salt enters the egg, causing protein salts to aggregate and precipitate. This "salting out" of the protein, which acts as an emulsifier, weakens its ability to emulsify fat. Once dispersed into tiny oil droplets, they aggregate into larger droplets, creating the yolk oily effect that enhances the taste and appearance of the salted egg.

[0004] Due to the curing process, excessive salt seeps into raw eggs, resulting in a high salt content in raw salted eggs. Therefore, desalting is necessary after curing. Cured raw salted eggs are typically soaked in light salt water, clean water, or a soaking liquid, with the water changed daily for about seven days to reduce the saltiness. This type of liquid soaking often results in uneven saltiness, with the egg appearing lighter on the outside and more concentrated on the inside. Furthermore, this desalination method is inefficient, and prolonged soaking can affect the egg's taste. Summary of the Invention

[0005] In view of the fact that the salty eggs are desalted by liquid immersion after pickling, there is an uneven saltiness problem that the surface is light and the inside is thick after immersion, and the desalination method is inefficient. Long-term liquid immersion will also affect the taste of the eggs. This application proposes a device for desalting salted eggs by immersing them in hot and humid gas to improve these problems of the liquid immersion desalination method.

[0006] A salted egg desalting device comprises an egg rack, a box body, an upper heating element, a lower heating element and an air intake assembly.

[0007] The egg rack has a plurality of sets of two opposing support members, and the two opposing support members can support an egg from two longitudinal sides and expose the egg on two transverse sides.

[0008] The box body has a cavity for accommodating the egg rack; a plurality of staggered upper air outlets and a plurality of lower air outlets are arranged in the box body; the upper air outlets lead to one lateral side of the two opposite support members, and the lower air outlets lead to the other lateral side of the two opposite support members.

[0009] The upper heating element is installed above the plurality of upper air outlets, and the lower heating element is installed below the plurality of lower air outlets.

[0010] The air intake assembly includes an upper moisture pipe and a lower moisture pipe; the upper moisture pipe leads to the upper heating element; and the lower moisture pipe leads to the lower heating element.

[0011] By adopting the above technical solution, the two opposing support members can support an egg from both longitudinal sides, leaving the egg exposed on both lateral sides. The upper air outlet opens to one lateral side of the two opposing support members, i.e., to one lateral side of the egg, and the lower air outlet opens to the other lateral side of the two opposing support members, i.e., to the other lateral side of the egg. The opposing airflows form a circular airflow around the vertical surface of the egg, which helps to remove salt-laden airflow precipitated from the egg surface, thereby improving desalination efficiency. The upper and lower heating elements can heat the upper and lower moist airflows, respectively, and then blow them over the egg surface. Compared to cool or dry air, the moist, hot airflow is more likely to penetrate the eggshell and enter the egg white and yolk, and is also more likely to seep out of the eggshell. The penetration process removes salt from the egg yolk and egg white, thereby reducing the salt content of the salted egg. The moist, hot airflow permeation method of this device, due to the strong penetration of the moist, hot air into the egg, penetrates evenly, reducing the salt content evenly. As a result, the saltiness of the desalted salted egg is more uniform throughout, resulting in a better taste and high desalination efficiency. However, the desalination method of liquid immersion is not as permeable as hot and humid air, resulting in uneven saltiness, with the surface being light and the interior being thick. During the desalination process using this device, the temperature, humidity, and air pressure of the hot and humid air are controlled to prevent the raw eggs from being cooked, thereby effectively desalting the salted eggs.

[0012] As an improvement to the salted egg desalting device, the support member is a smooth M-shaped support bar, the middle recess of the M-shaped support bar is an arc segment; the positions of the two arc segments of the two opposite M-shaped support bars are relatively fixed.

[0013] By adopting the above technical solution, the smooth M-shaped support strips are less likely to damage the eggshell, and the two opposite arc sections of the two opposite M-shaped support strips can support the egg, so that the egg is suspended in the air, the two lateral sides of the egg are completely exposed, and the two longitudinal sides of the egg are basically exposed, which is conducive to airflow passing through the sides of the egg and is conducive to desalination of the egg.

[0014] As an improvement to the salted egg desalting device, the egg rack further comprises a base plate and a plurality of legs; the plurality of legs are mounted under the base plate; a plurality of transverse strip holes are provided on the base plate; and every two of the M-shaped support bars are fixed relatively to the longitudinal sides of the strip holes.

[0015] By adopting the above technical solution, a plurality of transverse strip holes are opened on the base plate, and every two M-shaped support strips are fixed relatively to each other on the longitudinal sides of the strip hole, forming a structure that can support the egg. The support structure has a very small wrapping area for the egg, which can leave the surrounding side of the egg basically exposed, which is conducive to the circulation of airflow, thereby carrying away the salt-containing airflow and improving the desalination efficiency.

[0016] As an improvement to the salted egg desalting device, both outer edges of the M-shaped support strip are arranged longitudinally and are perpendicular to the strip-shaped holes.

[0017] By adopting the above technical solution, the outer sides of adjacent M-shaped support bars are parallel to each other, and multiple M-shaped support bars can be arranged relatively closely and at a suitable distance, which is conducive to maintaining a higher wind speed between adjacent eggs and improving desalination efficiency.

[0018] As an improvement to the salted egg desalting device, the upper air outlet and the lower air outlet are both square and adjacent upper air outlets are arranged tangentially, with the tangent surface being a longitudinal vertical surface located between the two support members.

[0019] By adopting the above technical solution, the wind from the upper air outlet and the lower air outlet can blow over half of the egg from the upper and lower directions respectively, thereby increasing the blowing force on the egg. The airflow will flow in a circular shape along the surface of the eggshell, which is conducive to removing the salt and moisture airflow on the surface of the eggshell and improving the desalination efficiency.

[0020] As an improvement to the salted egg desalting device, the salted egg desalting device further includes an upper air guide frame and a lower air guide frame; the upper air guide frame is in a conical shell shape and is installed between the upper air outlet and the upper heating element; the top end of the upper air guide frame is adjacent to the upper heating element; the upper air guide frame is evenly provided with a plurality of ventilation holes; the lower air guide frame is in a conical shell shape and is installed between the lower air outlet and the lower heating element; the top end of the lower air guide frame is adjacent to the lower heating element; the lower air guide frame is evenly provided with a plurality of ventilation holes.

[0021] By adopting the above technical solution, the upper air guide frame and the lower air guide frame are in the shape of a cone shell and are evenly provided with multiple ventilation holes. The structures of the upper air guide frame and the lower air guide frame can be the same and can be symmetrically arranged or staggered. The evenly distributed ventilation holes can ventilate everywhere. At the same time, the cone structure can guide the wind in the middle to the surroundings, balance the wind force in the middle and the surroundings, improve the wind speed in the surroundings, and adjust the wind speed in the middle and the wind speed in the surroundings to be more equal, so that the wind speed out of the multiple upper air outlets is relatively equal, and the wind speed out of the multiple lower air outlets is also relatively equal, so that the wind speed for blowing the salted eggs at various positions in the box is uniform, and a similar desalination effect is achieved after the same desalination time, which is convenient for mass production and improves the desalination quality.

[0022] As an improvement to the salted egg desalting device, the air intake assembly further includes a water vapor intake pipe, a water vapor blower, an air intake pipe, an air blower and a mixed gas pipe; the water vapor intake pipe and the air intake pipe merge into the mixed gas pipe; the water vapor blower is arranged on the water vapor intake pipe; the air blower is arranged on the air intake pipe; the mixed gas pipe is bifurcated into the upper moisture pipe and the lower moisture pipe.

[0023] By adopting this technical solution, steam and air are introduced through a steam blower and an air blower, mixed and injected into the upper and lower heating elements of the chamber. This mixed airflow then enters the chamber, creating a moist, hot airflow that impacts the salted eggs, desalting them. The blower power can be adjusted to adjust the humidity and flow rate of the air to meet the desalination requirements.

[0024] As an improvement to the salted egg desalination device, the device further includes a temperature sensor, a humidity sensor, and an air pressure sensor, all mounted within the cavity of the housing; and a controller. The controller is connected to the temperature sensor, the upper heating element, and the lower heating element. The controller is also connected to the humidity sensor, the air pressure sensor, the steam blower, and the air blower.

[0025] Using this technical solution, a temperature sensor senses the temperature within the chamber, and a controller regulates the power of the upper and lower heating elements to maintain the desired temperature. A humidity sensor and a pressure sensor sense the humidity and pressure within the chamber, and the controller regulates the power of the steam and air blowers to maintain the desired humidity and pressure. By controlling the appropriate temperature, humidity, and pressure, efficient and uniform desalination is achieved.

[0026] As an improvement to the salted egg desalting device, the salted egg desalting device also includes an exhaust assembly; the exhaust assembly includes a first exhaust pipe, a piston, a spring, and a second exhaust pipe; the first exhaust pipe is connected to the cavity of the box body; the end of the first exhaust pipe is closed; the piston is interference-fitted in the first exhaust pipe; one end of the spring is fixed to the inner wall of the end of the first exhaust pipe, and the other end is connected to the piston; an exhaust hole is provided in the side wall of the first exhaust pipe; the second exhaust pipe wraps the first exhaust pipe and accommodates the exhaust hole in the second exhaust pipe; when the spring is naturally extended, the piston is located at the front end of the exhaust hole, blocking the airflow from the cavity to the exhaust hole.

[0027] By adopting the above technical solution, under normal pressure, the spring naturally presses against the piston, and the exhaust port is closed to the cavity. As the air pressure increases, the spring is compressed, and after the air pressure reaches a certain value, the piston releases the blocking effect on the exhaust hole, and the gas in the cavity flows out from the exhaust hole. This setting ensures that the air pressure in the box must reach a certain value before it can flow out of the system, so that the air pressure in the box is maintained at a certain value to meet the air flow permeation desalination requirements.

[0028] As an improvement to the salted egg desalination device, the salted egg desalination device further includes an exhaust purification device, which includes a first conduit, a first container, a second conduit, a second container, and a third conduit, wherein the second container is loaded with a liquid capable of absorbing salt; one end of the first conduit receives gas exhausted from the box, and the other end is seamlessly inserted into the first container; one end of the second conduit is seamlessly inserted into the first container, and the other end is seamlessly inserted into the second container and immersed in the liquid; one end of the third conduit is seamlessly inserted into the second container, and the other end faces the outside of the second container.

[0029] By adopting this technical solution, the gas exhausted from the housing can first enter the first container and then the second container. Salt in the gas flow can be absorbed by the liquid in the second container, which can be water. If the air pressure in the housing decreases, the second conduit draws the liquid into the first container, preventing the liquid from being directly sucked into the housing. The first container acts as a buffer to prevent backflow.

[0030] In summary, the salted egg desalination device of the present application has the following beneficial effects:

[0031] The staggered flow of moist, hot air from the upper and lower chambers creates a circular airflow around the vertical surface of the eggs, effectively removing salty air from the egg surface and improving desalination efficiency. Because the moist, hot air penetrates the eggs more effectively, it penetrates evenly and reduces salt content evenly. As a result, the saltiness of the desalted salted eggs is more uniform throughout, resulting in a better-tasting, more efficient salting process.

[0032] The smooth M-shaped support strips are less likely to damage the eggshell, and the two opposite arc sections of the two opposite M-shaped support strips can support the egg, so that the egg is suspended in the air. The support structure has a very small wrapping area for the egg, which can leave the sides of the egg basically exposed, which is conducive to airflow passing through the sides of the egg and is beneficial to the desalination of the egg.

[0033] The upper air outlet and the lower air outlet are both square, and the adjacent upper air outlet and the lower air outlet are arranged tangentially. The wind coming out of the upper air outlet and the lower air outlet can blow over half of the egg from the upper and lower directions respectively, thereby increasing the blowing force on the egg. The airflow will flow in a circular shape along the surface of the eggshell, which is conducive to taking away the salt and moist airflow on the surface of the eggshell and improving the desalination efficiency.

DETAILED DESCRIPTION

[0043] Some embodiments of the salted egg desalination device are described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1 and Figure 2 A salted egg desalting device includes an egg rack 1, a box body 2, an upper heating element 3, a lower heating element 4 and an air intake component 5.

[0045] The box body 2 can be a square box body. The box body 2 has an upper partition 201 and a lower partition 202, and a cavity capable of accommodating the egg rack 1 is separated between the upper partition 201 and the lower partition 202.

[0046] See also Figure 3 The upper partition 201 is provided with multiple rows of upper air outlets 2011 , and the lower partition 202 is provided with multiple rows of lower air outlets 2021 .

[0047] The air intake assembly 5 includes an upper moisture pipe 501 and a lower moisture pipe 502. The upper moisture pipe 501 leads to the upper heating element 3. The lower moisture pipe 502 leads to the lower heating element 4. The upper heating element 3 can be multiple electric heating wires installed in parallel above multiple rows of upper air outlets 2011 to heat the humid air flow entering the upper part of the housing 2. The lower heating element 4 can be multiple electric heating wires installed in parallel below multiple rows of lower air outlets 2021 to heat the humid air flow entering the lower part of the housing 2.

[0048] See also Figure 4The egg rack 1 includes multiple sets of two opposing support members capable of supporting an egg from both sides in the horizontal longitudinal direction, leaving the egg exposed on both sides in the horizontal direction. For example, the support members may be smooth M-shaped support bars 101, which may be formed by bending a straight steel bar into an M shape, with three smooth curved bends. The central recess of the M-shaped support bar 101 is a circular arc segment 1011, and the two circular arc segments 1011 of the two opposing M-shaped support bars 101 are fixed relative to each other.

[0049] The smooth M-shaped support bars 101 are designed so that the two opposing arc segments 1011 of the two opposing M-shaped support bars 101 can wrap around the egg from both sides, making the egg suspended in the air. Furthermore, the salted egg 6 is less likely to break after a slight collision with the smooth M-shaped support bars 101. The M-shaped support bars 101 can completely expose both lateral sides of the egg and substantially expose both longitudinal sides of the egg, facilitating the passage of moist and hot air around the egg and improving the desalination efficiency of the salted egg 6.

[0050] like Figure 3 Optionally, the egg rack 1 further comprises a base plate 102 and a plurality of legs 103. The four legs 103 are fixed at the four corners of the base plate 102. Figure 4 The upper surface of the lower partition 202 is provided with four alignment grooves 2022 for aligning the four legs 103 .

[0051] like Figure 4 Optionally, a plurality of transverse strip holes 1021 are provided on the substrate 102, for example, three parallel and equidistant strip holes 1021. Every two M-shaped support bars 101 are relatively fixed on the horizontal and longitudinal sides of the strip holes 1021. Each strip hole 1021 can be welded with multiple pairs of opposing M-shaped support bars 101 at equal intervals, for example, seven pairs. Every two opposing M-shaped support bars 101 form a support structure that can support the salted egg 6. The support structure has a minimal wrapping area for the egg, which can leave the egg's periphery substantially exposed, thereby facilitating airflow circulation, thereby carrying away the salty airflow and improving the desalination efficiency of the salted egg 6.

[0052] like Figure 4 Optionally, both outer edges of the M-shaped support bars 101 are arranged horizontally and longitudinally, perpendicular to the strip-shaped holes 1021. The outer edges of adjacent M-shaped support bars 101 are parallel to each other. Multiple M-shaped support bars 101 can be arranged relatively closely together, with an appropriate spacing, to maintain a high wind speed between adjacent eggs and improve desalination efficiency. For example, laterally adjacent M-shaped support bars 101 can be placed right next to each other, or separated by the distance of an egg (the diameter at the thickest point), half an egg, or two eggs.

[0053] like Figure 3 and Figure 4Optionally, a row of upper air outlets 2011 is provided above each strip hole 1021, and a row of lower air outlets 2021 is provided below each strip hole 1021. Each row of upper air outlets 2011 may include multiple upper air outlets 2011 arranged at equal distances, and each row of lower air outlets 2021 may include multiple lower air outlets 2021 arranged at equal distances.

[0054] See also Figure 4 and Figure 5 The upper air outlet 2011 and lower air outlet 2021 in the same row are staggered and arranged in sequence, respectively blowing air at both sides of the multiple eggs in the same row. This is equivalent to the upper air outlet 2011 pointing vertically downward toward one lateral side of the two opposing support members, i.e., toward one lateral side of the salted eggs 6, while the lower air outlet 2021 points vertically upward toward the other lateral side of the two opposing support members, i.e., toward the other lateral side of the salted eggs 6. The opposing airflows form annular airflows 2031 on both sides of the vertical surface of the eggs, which facilitates the flow and discharge of salt-laden air from the surface of the salted eggs 6, thereby improving desalination efficiency.

[0055] The upper heating element 3 and the lower heating element 4 can heat the upper and lower moist air flows respectively, and then blow them on the surface of the egg. Compared with cool wind and dry wind, the moist and hot air flow is easier to penetrate the eggshell and enter the egg white and egg yolk. The moist and hot air flow is also easy to seep out of the eggshell, and the salt in the egg yolk and egg white is brought out during the penetration process, thereby reducing the salt content of the salted egg 6.

[0056] This device uses a hot and humid air flow to infiltrate the salted eggs 6 for desalination. Since the hot and humid air has a strong osmotic effect on the eggs, it penetrates evenly and reduces the salt content evenly. Therefore, the saltiness of the salted eggs 6 inside and outside after desalination is relatively uniform, and the salted eggs 6 after desalination have a good taste and a high desalination efficiency. However, the liquid immersion desalination method is not as good as the hot and humid air, so it will cause the saltiness of the outer surface to be light and the inner surface to be dense. In the process of desalination using this device, the appropriate temperature, humidity, and air pressure of the hot and humid air are controlled to prevent the raw eggs after pickling from being cooked, which can better desalinate the salted eggs 6.

[0057] It should be noted that salted egg 6 can be salted duck egg or salted chicken egg etc., and eggshell generally has 7000-17000 pores, and aperture is about 0.01-0.1mm.The droplet diameter of the hot and humid air adopted is 1-10 μm, and droplet can pass through the pores of eggshell, and enter in egg white and yolk through the eggshell endometrium, under the hot and humid air effect of circulation, the salt in egg white and yolk is taken out of by hot and humid air, and a part flows with hot and humid air and discharges circulatory system, and another part is deposited on eggshell surface, separates out and crystallizes in eggshell surface.After hot and humid air circulation process finishes, the salt on eggshell surface is cleaned, namely achieved salted egg 6 desalination.

[0058] See also Figure 6In a preferred embodiment, the upper air outlet 2011 and the lower air outlet 2021 are both square, and the adjacent upper air outlet 2011 and lower air outlet 2021 are arranged tangent to each other. The tangent surface 2041 is a longitudinal vertical surface, located in the middle of the two supporting members, so that the wind from the upper air outlet 2011 and the lower air outlet 2021 can blow through half of the egg from the upper and lower directions respectively, directly aiming at the egg, with a greater blowing force on the egg, and the air flow will flow in a circular shape along the surface of the eggshell, which is conducive to taking away the salt and moist air flow on the surface of the eggshell and improving the desalination efficiency.

[0059] like Figure 3 In a preferred embodiment, the salted egg desalting device further comprises an upper air guide frame 7 and a lower air guide frame 8. The upper air guide frame 7 is in a conical shell shape and is installed between the upper air outlet 2011 and the upper heating element 3. The top end of the upper air guide frame 7 is adjacent to the upper heating element 3. The upper air guide frame 7 is evenly provided with a plurality of ventilation holes 701; the lower air guide frame 8 is in a conical shell shape and is installed between the lower air outlet 2021 and the lower heating element 4; the top end of the lower air guide frame 8 is adjacent to the lower heating element 4; the lower air guide frame 8 is evenly provided with a plurality of ventilation holes 701.

[0060] The upper air guide frame 7 and the lower air guide frame 8 are both in the shape of a cone shell, which can be a cone or a square cone, and are also evenly distributed with multiple ventilation holes 701. The diameter of the ventilation holes 701 can be 0.5~2cm. The diameters of the ventilation holes 701 can all be the same or different. For example, from the top to the surrounding areas, the diameters of the ventilation holes 701 increase successively to regulate the wind force in the center and the surrounding areas to similar values.

[0061] The structures of the upper air guide frame 7 and the lower air guide frame 8 can be the same and can be symmetrically arranged or staggered. The evenly distributed ventilation holes 701 allow the air guide frame to be ventilated everywhere. At the same time, the conical structure can guide the wind in the middle to the surroundings, balance the wind force in the middle and the surroundings, increase the wind speed in the surroundings, and regulate the wind speed in the middle and the wind speed in the surroundings to be more equal, so that the wind speed coming out of the multiple upper air outlets 2011 is relatively equal, and the wind speed coming out of the multiple lower air outlets 2021 is also relatively equal, so that the purge wind speed of the salted eggs 6 at various positions in the box 2 is uniform. After the same desalination time, each salted egg 6 achieves a similar desalination effect, which is convenient for mass production and improves the effectiveness of desalination.

[0062] Please refer to Figure 1 and Figure 7 In an optional embodiment, the air intake assembly 5 further includes a steam intake pipe 503, a steam blower 504, an air intake pipe 505, an air blower 506 and a mixed gas pipe 507. The air intake assembly 5 may also include a steam generator 508 and an air source 509. Figure 1 and Figure 7The steam blower 504, air blower 506, steam generator 508 and air source 509 are shown for illustration purposes only. The steam inlet pipe 503 is connected to the steam generator 508. The air inlet pipe 505 is connected to the air source 509.

[0063] In the air intake assembly 5, the water vapor intake pipe 503 and the air intake pipe 505 merge into a mixed gas pipe 507. A water vapor blower 504 is mounted on the water vapor intake pipe 503. An air blower 506 is mounted on the air intake pipe 505. The mixed gas pipe 507 branches into an upper moisture pipe 501 and a lower moisture pipe 502, which then lead into the housing 2.

[0064] During use, water vapor and air are introduced by the steam blower 504 and the air blower 506, mixed and then injected into the upper heating element 3 and the lower heating element 4 of the housing 2 and enter the cavity, forming a moist hot air flow to flush the salted eggs 6, thereby desalting the salted eggs 6. During use, the power of the blower can be adjusted to adjust the humidity and flow rate of the moisture to meet the humidity, air pressure, and temperature requirements for desalting the salted eggs 6.

[0065] Please refer to Figure 3 In an optional embodiment, the salted egg desalination device further includes a temperature sensor 9, a humidity sensor 10, and an air pressure sensor 11, all of which are installed in the cavity of the housing 2. The salted egg desalination device further includes a controller. The controller is connected to the temperature sensor 9, the upper heating element 3, and the lower heating element 4. The controller is connected to the humidity sensor 10, the air pressure sensor 11, the steam blower 504, and the air blower 506. The temperature sensor 9 senses the temperature inside the housing 2, and the controller regulates the power of the upper heating element 3 and the lower heating element 4 to regulate the temperature so that the temperature meets the set requirements. The humidity sensor 10 and the air pressure sensor 11 sense the humidity and air pressure inside the housing 2, and the controller regulates the power of the steam blower 504 and the air blower 506 to regulate the humidity and air pressure so that they meet the set requirements. Regulate appropriate temperature, humidity, and air pressure to achieve an efficient and uniform desalination effect.

[0066] like Figure 8In a preferred embodiment, the salted egg desalination device also includes an exhaust assembly 12. The exhaust assembly 12 includes a first exhaust pipe 1201, a piston 1202, a spring 1203 and a second exhaust pipe 1204. The first exhaust pipe 1201 is connected to the cavity of the box body 2. The end of the first exhaust pipe 1201 is closed. The piston 1202 is interference fit in the first exhaust pipe 1201. One end of the spring 1203 is fixed to the inner wall of the end of the first exhaust pipe 1201, and the other end is connected to the piston 1202. An exhaust hole 1205 is provided on the side wall of the first exhaust pipe 1201. The second exhaust pipe 1204 wraps the first exhaust pipe 1201 and accommodates the exhaust hole 1205 in the second exhaust pipe 1204. When the spring 1203 is naturally extended, the piston 1202 is located at the front end of the exhaust hole 1205, blocking the airflow from the cavity to the exhaust hole 1205.

[0067] By adopting the above technical solution, under atmospheric pressure, spring 1203 naturally presses against piston 1202, closing the passage from the cavity to the exhaust port. As the air pressure increases, spring 1203 is compressed. Once the air pressure reaches a certain value, piston 1202 releases its blocking effect on exhaust port 1205, allowing the gas in housing 2 to flow out through exhaust port 1205. This arrangement ensures that the air pressure in housing 2 must reach a certain value before it can be discharged through exhaust assembly 12, thereby maintaining the air pressure in housing 2 at a constant value, meeting the requirements of this solution for desalting the salted egg 6 using moist hot air flow.

[0068] like Figure 8 In a preferred embodiment, the salted egg desalination device further includes an exhaust gas purification device 13, which comprises a first conduit 1301, a first container 1302, a second conduit 1303, a second container 1304, and a third conduit 1305. The second container 1304 contains a liquid capable of absorbing salt. The opening of the first container 1302 is sealed with a first rubber stopper 1306. The opening of the second container 1304 is sealed with a second rubber stopper 1307. One end of the first conduit 1301 receives exhaust gas from the housing 2, while the other end seamlessly passes through the first rubber stopper 1306 and is inserted into the first container 1302. One end of the second conduit 1303 seamlessly passes through the first rubber stopper 1306 and is inserted into the first container 1302. The other end seamlessly passes through the second rubber stopper 1307 and is inserted into the second container 1304, where it is immersed in the liquid. One end of the third conduit 1305 seamlessly passes through the second rubber stopper 1307 and is inserted into the second container 1304, with the other end discharging exhaust gas outward.

[0069] Gas exhausted from housing 2 enters first container 1302 before entering second container 1304. Salt in the gas stream is absorbed by the liquid, which can be water, in second container 1304. If the pressure within housing 2 decreases, second conduit 1303 draws the liquid into first container 1302, preventing it from being directly drawn into housing 2. First container 1302 acts as a buffer, preventing backflow.

[0070] The above are only preferred implementations of the present application. The scope of protection of the present application is not limited to the above embodiments. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principles of the present application should also be considered to fall within the scope of protection of the present application.
