Description

Technical Field

[0001] This invention relates to the field of preserved goose storage technology, specifically a sealed storage device for finished preserved goose products that is moisture-proof and insect-proof. Background Technology

[0002] Preserved goose is a traditional Chinese cured meat product, beloved by consumers for its unique flavor and rich nutrition. The processing of preserved goose involves curing and air-drying, resulting in a low moisture content but high fat content, often with a significant amount of oil on its surface. During storage, preserved goose is susceptible to the effects of environmental factors such as temperature, humidity, oxygen, and microorganisms, presenting the following main problems:

[0003] 1. Preserved goose is rich in unsaturated fatty acids, which are easily oxidized and rancid under the action of oxygen, producing a "rancid smell" that seriously affects the quality and safety of food. Traditional storage methods, such as hanging at room temperature or ordinary sealed packaging, are difficult to effectively control the oxygen concentration, resulting in a short shelf life.

[0004] 2. During storage, preserved geese are prone to infestation with stored grain pests such as cheese flies. After the eggs hatch, the larvae bore into the meat, causing serious losses. Current technology often uses chemical pesticides for pest control, but this poses a risk of pesticide residues and does not meet food safety requirements.

[0005] 3. If the oil seeping from the surface of the cured goose accumulates at the bottom of the container, it will be exposed to air for a long time, accelerating oxidation. At the same time, soaking the meat in oil will cause the flavor to deteriorate. Existing storage devices lack effective oil collection and drainage mechanisms, requiring users to frequently open the container to clean the oil, thus disrupting the sealed environment.

[0006] 4. The shape of preserved geese is irregular and their bones are hard. Traditional stacking storage methods can easily cause them to be squeezed and deformed, and their skin can be damaged. In addition, close contact between multiple preserved geese can easily lead to cross-infection of mold and pests. Summary of the Invention

[0007] The purpose of this invention is to provide a sealed storage device for moisture-proof and insect-proof preserved goose products, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A sealed storage device for moisture-proof and insect-proof preserved goose includes a storage box and a door rotatably installed on the front side of the storage box. Several hanging brackets are installed inside the storage box in both horizontal and vertical directions. An oil collection basin is embedded in the bottom of the storage box. An exhaust fan assembly is connected to the upper end of the storage box, and an intake fan assembly is connected to the lower end of one side of the storage box. A deoxygenation storage box is installed on the upper end of the inner wall of the storage box near the intake fan assembly, and a germicidal lamp is installed on the upper end of the inner side wall of the storage box near the deoxygenation storage box.

[0010] As a further embodiment of the present invention: the grease collection basin includes a sealed basin body, the upper part of the sealed basin body is inclined and recessed towards the center, and an oil inlet is provided at the center; a siphon bend one and a siphon bend two are respectively embedded on one side of the upper end of the sealed basin body, the upper ends of the siphon bend one and the siphon bend two are connected to a connecting pipe, and the junction of the connecting pipe and the siphon bend two is connected to an oil drain pipe.

[0011] As a further embodiment of the present invention: a pipe cap is provided at the upper end of the connecting pipe, and an oil drain valve is installed on the oil drain pipe.

[0012] As a further embodiment of the present invention: the lowest point of the first siphon bend in the sealed basin is higher in the vertical direction than the lowest point of the second siphon bend in the sealed basin, and the intersection point of the first siphon bend and the connecting pipe is higher in the vertical direction than the intersection point of the second siphon bend and the connecting pipe.

[0013] As a further embodiment of the present invention: the exhaust fan assembly includes a fan housing and an exhaust fan installed inside the fan housing. A filter cylinder is provided on the inner side of the fan housing at the upper end of the exhaust fan. A fixing plate is provided at the upper end of the filter cylinder, and a filter screen is provided on the inner side of the filter cylinder.

[0014] As a further embodiment of the present invention: a drive motor is installed at the center of the upper end of the fixed disk, the output end of the drive motor is connected to a rotating disk inside the filter cartridge, a plurality of fan-shaped holes II are evenly opened on the inner side of the fixed disk outside the drive motor, and a plurality of fan-shaped holes I that match the fan-shaped holes II are opened on the inner side of the rotating disk.

[0015] As a further embodiment of the present invention: the suspension frame assembly includes a track and a plurality of U-shaped frames located below the track, wherein a crossbar is fixedly connected to the inner side of the upper end of each U-shaped frame, and a plurality of hooks are installed on the crossbar.

[0016] As a further aspect of the present invention: a screw is installed on both sides of the upper end of each U-shaped frame, and a vehicle body is fixedly connected to the upper end of each screw. Two sets of pulleys are installed on the vehicle body, and the two sets of pulleys are slidably arranged in the track.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention enables the grouping and hanging of cured geese by setting up a hanging frame assembly; gravity is used to allow the oil seeping out of the cured geese to drip off naturally and separate, preventing the meat from being soaked in the oil and accelerating oxidation and deterioration; at the same time, the U-shaped frame in the hanging frame assembly can form an isolation and protection for each group of cured geese, preventing multiple cured geese from being stacked and squeezed and deformed, ensuring a uniform microenvironment around each cured goose, and effectively preventing cross-infection of mold and pests.

[0019] The grease collection basin adopts a sealed basin body with a double siphon bend structure. Through the high and low position difference design, it forms an automatic start and stop siphon grease discharge mechanism. Users do not need to open the box door and can realize periodic automatic grease discharge. It effectively avoids the grease from being exposed to air for a long time and producing a rancid smell, while preventing the sealing environment from being damaged due to frequent opening of the box.

[0020] Both the intake fan assembly and the exhaust fan assembly can achieve stepless adjustment of the air exchange speed; and can prevent outside air from entering, avoiding the accumulation of mold that would cause the flavor of the preserved goose to deteriorate, while also preventing excessive drying that would cause the meat to shrink.

[0028] Please see Figures 1-6 In this embodiment of the invention, a moisture-proof and insect-proof sealed storage device for finished preserved goose includes a storage box 1 and a door 2 rotatably installed on the front side of the storage box 1. A magnetic sealing strip is provided between the door 2 and the storage box 1 to ensure an airtight seal when closed. Several hanging bracket assemblies 3 are installed inside the storage box 1 in both horizontal and vertical directions. An oil collection basin 4 is embedded at the bottom of the storage box 1. An exhaust fan assembly 8 is connected to the upper end of the storage box 1, and an intake fan assembly 5 is connected to the lower end of one side of the storage box 1. A deoxygenation storage box 6 is installed on the inner wall of the storage box 1 near the upper end of the intake fan assembly 5. A deoxygenation storage box 6 can be placed inside the deoxygenation storage box 6 to reduce the oxygen concentration inside the storage box 1, such as to make the oxygen concentration <0.5%, thus blocking the aerobic environment required for adult insect hatching at the source and inhibiting oil oxidation. The deoxygenation storage box 6 can be a pull-out structure, with its front end set with... The storage box 6 features a breathable grille to ensure adequate contact between the oxygen absorber pack and the internal air. A transparent observation window on the outside of the oxygen absorber storage box 6 allows for direct observation of color changes in the oxygen absorber pack to determine its failure status. A germicidal lamp 7 is installed on the inner wall of the storage box 1 near the upper part of the oxygen absorber storage box 6. This lamp emits a specific wavelength of cold light, such as 405nm violet light, which repels pests and flies and kills their eggs. It does not generate heat radiation that could cause the wax goose to deteriorate, thus achieving physical insect prevention and avoiding chemical pesticide residues. The inner wall of the storage box 1 is also equipped with a temperature and humidity sensor to monitor internal environmental parameters in real time and to automatically adjust them in conjunction with the intake fan assembly 5 and exhaust fan assembly 8. A control panel is embedded in the door 2, electrically connected to the temperature and humidity sensor, intake fan assembly 5, exhaust fan assembly 8, and germicidal lamp 7. The control panel includes a display screen and several operation buttons for displaying internal temperature and humidity parameters and manually controlling the start and stop of each actuator.

[0029] exist Figure 1 , Figure 2 and Figure 3In the hanging frame assembly 3, there is a track 34 and several U-shaped frames 31 located below the track 34, such as three U-shaped frames 31. A crossbar 32 is fixedly connected to the inner side of the upper end of each U-shaped frame 31, and several hooks 35 are installed on the crossbar 32, such as three hooks 35. The hooks 35 are made of food-grade 304 stainless steel, and their ends are equipped with anti-detachment hooks to prevent the cured goose from accidentally falling off during pulling or moving. One cured goose is hung on each hook 35, so three cured geese can be hung as a group within the U-shaped frames 31. Gravity allows the oil seeping from the cured goose to drip off naturally, preventing the meat from soaking in the oil and accelerating oxidation and spoilage. Meanwhile, the U-shaped frame 31 can isolate and protect the three preserved geese inside, preventing them from piling up together and becoming squeezed and deformed. It also ensures a uniform microenvironment around each preserved goose, effectively preventing cross-infection of mold and pests. Each U-shaped frame 31 has a screw 37 installed on both sides of its upper end. The upper end of each screw 37 is fixedly connected to a car body 36. Two sets of pulleys 33 are installed on the car body 36. The two sets of pulleys 33 are slidably set in the track 34. Therefore, when the U-shaped frame 31 is pushed or pulled by hand, the pulleys 33 slide along the track 34, and the position of the U-shaped frame 31 can be adjusted along the track 34, thereby changing the position of the preserved geese.

[0030] exist Figure 1 and Figure 4In the process, the exhaust fan assembly 8 includes a fan housing 82 and an exhaust fan 81 installed inside the fan housing 82. A filter cartridge 84 is located on the inner side of the fan housing 82 above the exhaust fan 81. A fixing plate 87 is located at the upper end of the filter cartridge 84, and a filter screen 83 is located on the inner side of the filter cartridge 84. The filter screen 83 has a multi-layer composite structure, including a pre-filter layer and a high-efficiency filter layer. The pre-filter layer is used to intercept large dust particles and insect eggs, while the high-efficiency filter layer is used to filter fine dust and mold spores. The fixing plate 87, filter cartridge 84, and fan housing 82 are fixedly connected together by screws. A drive motor 88 is installed at the center of the upper end of the fixing plate 87. The output end of the drive motor 88 is connected to a rotating disk 85 inside the filter cartridge 84. Several fan-shaped holes 89 are evenly distributed on the inner side of the fixing plate 87 outside the drive motor 88. Several fan-shaped holes 86 matching the fan-shaped holes 89 are distributed on the inner side of the rotating disk 85. The motor 88 drives the rotating disk 85 to rotate. When the second sector hole 89 and the first sector hole 86 are completely or partially overlapped, the exhaust fan 81 is activated. The exhaust fan 81 can then exhaust the moldy and humid air in the storage box 1 through the filter screen 83, the first sector hole 86 and the second sector hole 89 to the external environment. The greater the overlap between the second sector hole 89 and the first sector hole 86, the faster the exhaust speed. The inlet fan assembly 5 has the same structure as the exhaust fan assembly 8. Similarly, the inlet fan assembly 5 can draw external air into the storage box 1 to achieve ventilation and prevent moldy odors from causing the preserved goose to spoil. When the second sector hole 89 and the first sector hole 86 are completely misaligned, a sealing structure is formed between the fixed disk 87 and the rotating disk 85, which can effectively prevent external air from entering the storage box 1. The filter cartridge 84 is equipped with a detachable activated carbon adsorption layer to adsorb odors that may be brought in during the ventilation process, further ensuring the cleanliness of the storage environment.

[0031] exist Figure 1 , Figure 5 and Figure 6In the process, the grease collection basin 4 includes a sealed basin body 41. The upper part of the sealed basin body 41 is inclined and recessed towards the center, and an oil inlet 42 is provided at the center. A siphon bend 43 and a siphon bend 47 are respectively embedded on one side of the upper end of the sealed basin body 41. The upper ends of the siphon bend 43 and the siphon bend 47 are connected to a connecting pipe 45. The junction of the connecting pipe 45 and the siphon bend 47 is connected to an oil drain pipe 46. The upper end of the connecting pipe 45 is provided with... A pipe cap 44 is provided, and an oil drain valve 48 is installed on the oil drain pipe 46. Both the pipe cap 44 and the oil drain valve 48 are located outside the storage box 1. The lowest point of the first siphon bend 43 in the sealed basin 41 is higher in the vertical direction than the lowest point of the second siphon bend 47 in the sealed basin 41. The intersection point of the first siphon bend 43 and the connecting pipe 45 is higher in the vertical direction than the intersection point of the second siphon bend 47 and the connecting pipe 45. During the storage process of the preserved goose... Grease will seep out and drip down, entering the sealed basin 41 through the oil inlet 42. Once the grease collected in the sealed basin 41 covers the second siphon bend 47 and the first siphon bend 43, the cap 44 is removed from the connecting pipe 45, and grease is poured into the connecting pipe 45. The grease then enters the first siphon bend 43, the second siphon bend 47, and the drain pipe 46. When the first siphon bend 43, the second siphon bend 47, and the drain pipe 46 are full of grease... After grease removal, cover the connecting pipe 45 with the cap 44, then open the drain valve 48, and the grease in the drain pipe 46 will flow outwards. At the same time, under the siphon effect, the grease in the sealed basin 41 will be drawn upwards into the first siphon bend 43 and the second siphon bend 47, then gather in the connecting pipe 45, and then flow out from the drain pipe 46. The grease can be collected in the basin at the bottom of the drain pipe 46. This allows the grease in the sealed basin 41 to be discharged even when the box door 2 cannot be opened.

[0032] When the grease in the sealed basin 41 drops to the bottom of the first siphon bend 43, some air in the storage box 1 enters the first siphon bend 43, and the first siphon bend 43, the connecting pipe 45 and the oil drain pipe 46 are all empty pipes, while the second siphon bend 47 is still full of grease, and the oil draining ends.

[0033] As the grease from the preserved goose continues to enter the sealed basin 41 through the oil inlet 42, it enters the siphon bend 43. When the grease level in the sealed basin 41 reaches the junction of the siphon bend 47 and the drain pipe 46, the grease in the siphon bend 47 begins to flow into the drain pipe 46. The suction generated in the siphon bend 43 draws the grease from the sealed basin 41 further into the siphon bend 43, then into the connecting pipe 45, and finally out through the drain pipe 46. This allows the grease in the sealed basin 41 to be discharged at any time once it reaches a certain height. Alternatively, the discharge time can be controlled by the drain valve 48. This prevents the grease from developing a rancid smell due to prolonged contact with air. The bottom of the sealed basin 41 is also equipped with a heating layer, which can assist in heating in low-temperature environments to liquefy the solidified grease and ensure smooth siphon discharge.

[0034] Working principle: When in use, first open the box door 2, pull out the U-shaped frame 31 along the track 34 via the pulley 33, and hang the preserved geese one by one on the hook 35. Multiple preserved geese can be hung in each U-shaped frame 31. The U-shaped frame 31 achieves partitioning and isolation to prevent squeezing and deformation. After pushing the U-shaped frame 31 back, close the box door 2. At this time, a relatively sealed space is formed inside the storage box 1.

[0035] The germicidal lamp 7 is activated, emitting a 405nm ultraviolet light band to physically prevent insects from entering the storage box 1, killing insect eggs and repelling pests, while not generating heat radiation to prevent the preserved goose from becoming oily and spoiled; the deoxygenating agent pack in the deoxygenated storage box 6 continuously absorbs oxygen inside, reducing the oxygen concentration to below 0.5%, destroying the aerobic environment required for pest hatching, and inhibiting the oxidation and rancidity of oil.

[0036] When the humidity inside the storage box 1 is too high or ventilation is required, the drive motor 88 drives the rotating disk 85 to rotate, so that the first fan-shaped hole 86 and the second fan-shaped hole 89 partially overlap. The intake fan assembly 5 and the exhaust fan assembly 8 are activated to introduce dry air from the outside, while the humid air inside is filtered through the filter screen 83 and the activated carbon adsorption layer and then discharged, achieving controlled ventilation and preventing the accumulation of moldy gas from causing the flavor of the preserved goose to deteriorate. After the ventilation is completed, the rotating disk 85 is reset so that the fan-shaped holes are completely misaligned, restoring the sealed state.

[0037] During storage, the grease that seeps out of the preserved goose drips down under gravity and collects at the oil inlet 42 along the inclined surface of the upper part of the sealed basin 41, entering the sealed basin 41 for storage. When it is necessary to drain the grease, the cap 44 is opened to pour grease into the connecting pipe 45, filling the siphon bend 43, the second siphon bend 47, and the drain pipe 46 with grease. After the cap 44 is closed, the drain valve 48 is opened, and the grease in the sealed basin 41 is automatically drawn out to the external container using the siphon principle. The entire process does not require opening the box door 2, thus avoiding damage to the internal sealing environment. When the grease level in the sealed basin 41 drops to the lowest point of the first siphon bend 43, the siphon stops. After the grease continues to drip to the set height, the siphon automatically resumes, realizing periodic automatic grease drainage and effectively preventing the grease from accumulating and oxidizing over a long period of time, resulting in a rancid smell.

[0038] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
