Description

Technical Field

[0001] The invention belongs to the technical field of keeping rice dumplings and bamboo leaves fresh, and in particular relates to a rice dumplings and bamboo leaves fresh-keeping cabinet. Background Art

[0002] As a core ingredient in traditional zongzi (zongzi), the freshness and quality of zongzi leaves directly impact the flavor, color, and food safety of the zongzi. However, existing preservation technologies struggle to meet the stringent requirements for post-harvest preservation, mold and fungus prevention, and categorized management of zongzi leaves, resulting in high raw material loss.

[0003] Specifically, first of all, fresh zong leaves are still metabolically active after being picked. Although conventional cold storage (2-4°C) can delay spoilage, low temperature stress causes two major problems: 1. Long-term refrigeration causes peroxidation of cell membrane lipids, resulting in water loss and shrinkage of leaves, making the zongzi easy to break; 2. Low temperature inhibits enzyme activity, leading to the disintegration of chlorophyll-protein complexes, resulting in an increase in the yellowing index of leaves and a loss of their emerald green appearance.

[0004] Secondly, the waxy layer on the surface of the rice dumplings leaves is prone to condensation when exposed to cold. However, if too much liquid accumulates on the leaves, it is easy to breed toxic fungi such as Aspergillus niger and Penicillium, and the condensed water accumulates in the grooves of the leaf veins. These liquids will dissolve the polysaccharides in the leaves to form mucus, which can easily accelerate the corruption of the leaves and produce a fishy smell. Summary of the Invention

[0005] The purpose of the present invention is to provide a rice dumpling and bamboo leaf fresh-keeping cabinet, which can place different bamboo leaves in different storage environments according to the storage requirements of the leaves, and can spray an appropriate amount of liquid on the leaves according to needs when delivering cold air to keep the leaves fresh.

[0026] The ventilation assembly and fresh-keeping assembly of the present invention can spray an appropriate amount of liquid on the blades as needed when delivering cold air, thereby keeping the blades fresh. When in use, the main body blows air into the blowing pipe through the air inlet pipe, thereby delivering cold air. If it is necessary to spray liquid on the blades for freshness preservation, the water pump draws liquid from the water tank and sends it into the air inlet pipe through the manifold to form water mist. Then, the cold air carries the water mist into the blowing pipe and is sent to the storage box to contact the blades, thereby delivering cold air and liquid to the blades at the same time, thereby improving the freshness of the leaves.

[0027] The partition assembly and ventilation assembly of the present invention can use the blowing gas to separate the stacked blades when delivering cold air and water mist, so that the blades can evenly receive the cold air and water mist for preservation, thereby improving the uniformity; when preserving, the gas blown out of the blowing pipe will enter the partition assembly and blow the folding tube to expand, causing the lifting plate and the partition plate to descend, and the descending partition plate is used to separate the vertically placed blades to create gaps, and then the cold air and water mist are sprayed out through the outlet on the folding tube, thereby realizing the separation and spraying of water mist on the blades, thereby improving the uniformity of leaf preservation.

[0050] Please see the attached Figures 1 to 2 、 Figures 6 and 7 、 Figures 12 to 15As shown, this embodiment provides a rice dumpling and bamboo leaf preservation cabinet, comprising:

[0051] The main body 10 has an inner cavity with a chilled area 12, a fresh-keeping area 13 and a sealed area 14;

[0052] The water filter assembly 20 includes a storage box 21. The inner cavity of the storage box 21 is movably connected to a water receiving plate 23. The water receiving plate 23 is fixedly connected to the inner cavity of the chilled area 12. The inner cavity of the storage box 21 is provided with a filter port 24 above the water receiving plate 23.

[0053] The ventilation assembly 30 includes an air inlet pipe 31, which is installed at the rear side of the inner cavity of the chilled area 12. An air blowing pipe 34 is installed at one side of the inner cavity of the storage box 21, and the air blowing pipe 34 is connected to the air inlet pipe 31. An air suction pipe 35 is installed at the other side of the storage box 21.

[0054] Fresh-keeping assembly 40, which includes a water tank 41. The water tank 41 is installed in the inner cavity of the main body 10. The inner cavity of the main body 10 is connected to a water pump 42. The inlet of the water pump 42 is connected to the water tank 41, and the outlet of the water pump 42 is connected to a manifold 43. The manifold 43 is connected to the air inlet pipe 31.

[0055] The partition assembly 50 includes a folding tube 52, the lower end of the folding tube 52 is fixedly connected to a lifting plate 53, and the lower end of the lifting plate 53 is fixedly connected to multiple groups of partition bars 54;

[0056] Among them, the chilled area 12, the fresh-keeping area 13 and the sealed area 14 are respectively used to store indigo leaves with different storage requirements. The air inlet pipe 31 injects cold air into the storage box 21 through the blowing pipe 34. When the cold air is input into the air inlet pipe 31, the water pump 42 sends the liquid in the water tank 41 into the air inlet pipe 31 to improve the humidity in the storage box 21.

[0057] When the air blowing pipe 34 is connected to the gas, the gas is blown into the folding tube 52 to expand it, pushing the lifting plate 53 and the dividing bar 54 down to separate the blades.

[0058] It should be noted that in order to ensure the normal use of the device and to achieve the effect of excess liquid discharge, when storing the indigo leaves, the leaves should be stored upright so that the excess liquid on the surface of the leaves can be quickly discharged to avoid affecting the storage of the leaves;

[0059] The main body 10 is an air-cooled refrigeration device as a whole, and has a built-in humidity control function (such as a fresh air refrigerator with a built-in humidity control function), and the chilled area 12 is used to store fresh leaves. The internal operating temperature should be maintained at 18 to 22 degrees Celsius, and the humidity should be maintained at 90% to 95% RH during operation to keep the fresh leaves flexible and fresh; the fresh-keeping area 13 is used to store dried leaves, and its operating temperature should be maintained at 20 to 25 degrees Celsius, and the humidity should be maintained at 30% to 40% RH; the sealed area 14 is used to store pre-steamed and sterilized leaves, and its operating temperature should be maintained at around 4 degrees Celsius, and the humidity should be maintained at 50% to 60% RH, thereby inhibiting enzyme activity and avoiding texture softening.

[0060] Preferably, in order to prevent the dried leaves from getting damp and becoming moldy, the sealing between the fresh-keeping area 13 and the sealing area 14 should be ensured, and the fresh-keeping area 13 should be equipped with a built-in circulating air function (this is a common technical structure in the prior art and will not be described in detail here) to prevent the leaves from getting damp and becoming moldy;

[0061] The temperature and humidity control in the chilled area 12, the fresh-keeping area 13 and the sealed area 14 should be adjustable according to demand, so as to cope with different storage scenarios.

[0062] In this embodiment, when in use, the reed leaves with different preservation requirements are placed in the chilled area 12, the fresh-keeping area 13 and the sealed area 14 respectively. Under normal conditions, the air inlet pipe 31 sends cold air into the blowing pipe 34 and the folding tube 52. At this time, the folding tube 52 expands, thereby pushing the lifting plate 53 and the dividing bar 54 down, and the dividing bar 54 is used to separate the vertically placed reed leaves so that air can evenly enter the gaps between the reed leaves. If it is necessary to spray water mist on the reed leaves to keep them fresh, the water pump 42 draws liquid from the water tank 41, and then the liquid forms water mist through the multi-head pipe 43 and is sent to the air inlet pipe 31, so that water mist can be sprayed out from the folding tube 52 to spray the reed leaves evenly to ensure uniformity. If there is too much water on the surface of the leaves, the accumulated water will be discharged from the downpipe 25 and the confluence pipe 26 through the water receiving plate 23.

[0063] Next, please refer to Figures 1 to 3 The front of the main body 10 is hinged with two sets of doors 11, which respectively cover the outside of the chilled area 12, the fresh-keeping area 13 and the sealed area 14. Three sets of storage plates 15 are placed in the inner cavity of the fresh-keeping area 13, and two sets of sealed boxes 17 are movably inserted into the inner cavity of the sealed area 14.

[0064] The lower ends of the three groups of storage plates 15 are fixedly connected to water collecting covers 16, which are intended to prevent the leaves stored in the fresh-keeping area 13 from coming into contact with the hot and humid air outside when the box door 11 is frequently opened and closed, causing condensation and accumulation of water droplets on their surfaces, thereby affecting the storage of the leaves. The lower ends of the inner cavities of the two groups of sealing boxes 17 are fixedly connected to filter plates 18, and a drainage outlet 19 is provided at the lower end of the front side of the sealing box 17 below the filter plate 18.

[0065] It should be noted that a sealing plug is movably inserted into the drain outlet 19 to improve the sealing effect.

[0066] Preferably, in order to ensure convenient subsequent use, the water collecting cover 16 should be set to a detachable structure, or a faucet for drainage should be set at its lower end (this is a common technical structure in the prior art and will not be described in detail), in order to facilitate the discharge of the liquid in the water collecting cover 16.

[0067] In this embodiment, during use, indigo leaves with different storage requirements are placed separately on a storage plate 15 in the fresh-keeping area 13 and in a sealed box 17 in the sealed area 14. The storage plate 15 in the fresh-keeping area 13 is designed to store relatively dry indigo leaves. The water collection cover 16 at its lower end effectively collects any condensed water droplets, preventing their accumulation and affecting the quality of the leaves. Within the sealed box 17 in the sealed area 14, a filter plate 18 further filters and collects excess liquid, which is then conveniently drained through a drain port 19, maintaining the environment within the sealed area 14. This effectively inhibits enzyme activity, prevents softening of the texture, and ensures that the pre-steamed, sterilized leaves maintain their quality for a long time.

[0068] Next, please refer to Figures 4 to 10 The water filter assembly 20 further includes a box cover 22, which is movably plugged into the front of the storage box 21;

[0069] Three groups of downpipes 25 are installed on the rear side of the inner cavity of the chilled area 12. The inlets of the three groups of downpipes 25 are respectively connected to the outlet of each group of water receiving plates 23, and the lower ends of the downpipes 25 are connected to a merging pipe 26. The outlet end of the merging pipe 26 passes through the main body 10 and is placed on the outside of the main body 10. The outer circle of the merging pipe 26 extending out of the main body 10 is fixedly connected to a valve 27.

[0070] It should be noted that a slope is provided at the lower end of the inner cavity of the water receiving plate 23, and the lower end of the slope is located at the outlet of the water receiving plate 23, so that the liquid falling from the filter port 24 can directly pass through the water receiving plate 23 into the confluence pipe 26;

[0071] The portion of the box cover 22 that contacts the storage box 21 is provided with a sealing layer to improve the sealing effect.

[0072] Preferably, under normal conditions, the valve 27 is always in a closed state. Only when the liquid stored in the confluence pipe 26 is higher than the inlet of the lower water pipe 25 at the bottom, the valve 27 will be opened to discharge the liquid. In order to ensure that excessive liquid stored in the confluence pipe 26 can be detected in time, a liquid level sensor can be installed in the inner cavity of the lower water pipe 25 to facilitate the detection of the height of the liquid stored in the confluence pipe 26.

[0073] In this embodiment, when excessive liquid accumulates on the leaves, it falls through filter 24 onto water receiving plate 23. It then flows through the sloped design of water receiving plate 23 into drain pipes 25. Three sets of drain pipes 25 collect the liquid into a confluence pipe 26. The design of confluence pipe 26 not only facilitates the unified discharge of excess liquid, but also, through the control of valve 27, ensures precise timing of discharge, effectively preventing the problem of liquid accumulation leading to leaf spoilage. When liquid accumulates to a certain level in confluence pipe 26, a liquid level sensor will generate a signal, prompting the operator to open valve 27 for discharge, ensuring a continuously optimized environment within the fresh-keeping cabinet.

[0074] Next, please refer to Figure 5 、 Figures 11 to 15 The ventilation assembly 30 also includes three sets of air outlet pipes 32, which are fixedly installed on the rear side of the inner cavity of the chilled area 12. The upper ends of the air inlet pipe 31 and the air outlet pipe 32 extend into the storage box 21 and are connected to a three-head pipe 33. The other two ends of the two three-head pipes 33 are connected to the blowing pipe 34 and the suction pipe 35 respectively.

[0075] The inner cavity of the storage box 21 is provided with four groups of storage cavities for storing indigo leaves, and the inner cavity of the storage box 21 is provided with a maintenance cavity for placing pipelines in the part outside the storage cavity, and the blowing pipe 34 and the suction pipe 35 are fixedly connected in the maintenance cavity, and the inlets and outlets of the blowing pipe 34 and the suction pipe 35 are extended into the storage cavity and fixedly connected with a connector 36, and the blowing pipe 34 and the suction pipe 35 are each provided with two groups, which are respectively connected to the two ports of the three-head pipe 33, and two groups of guide rails 37 are fixedly connected to the lower side of the inner cavity of the storage cavity, and the inner cavity of one group of guide rails 37 is slidably connected to a limit plate 38.

[0076] It should be noted that the air inlet pipe 31 and the air outlet pipe 32 are respectively connected to the air cooling system in the main body 10, and are intended to use the air inlet pipe 31 to transport cold air into the storage box 21 and to suck out the accumulated air through the air outlet pipe 32 to achieve the ventilation effect;

[0077] The surface of the limiting plate 38 is provided with a through groove, so as to prevent the limiting plate 38 from affecting the connection head 36 connected to the suction pipe 35 to extract gas;

[0078] The side of the limiting plate 38 close to the blowing pipe 34 is provided with a slope, which is intended to allow the indigo leaves to lean against the limiting plate 38 at an angle, thereby preventing the indigo leaves from being stored in insufficient quantity and placed vertically, thereby affecting the effect of draining the accumulated water.

[0079] The portion of the connector 36 that extends into the storage chamber is fixedly connected to a metal mesh, which improves the stability of gas flow and further refines the water mist blown out of the blowing pipe 34;

[0080] The lower end of the limiting plate 38 is fixedly connected to a magnetic plate, and the lower end of the inner cavity of the guide rail 37 is also installed with an adaptive magnetic component, so that the limiting plate 38 can be fixed to the inner cavity of the guide rail 37.

[0081] In this embodiment, during use, the limiting plate 38 is inserted into the appropriate guide rail 37 according to the number of leaves to be stored. After the leaves are placed in the storage box 21, the air inlet pipe 31 delivers cold air into the storage box 21, and the cold air enters the blowing pipe 34 through the three-pronged pipe 33. The blowing pipe 34 blows the cold air into the storage chamber, cooling and preserving the leaves. The suction pipe 35 extracts the accumulated air in the storage chamber through the connector 36, and this air is then discharged through the outlet pipe 32 to achieve a ventilation effect. This design not only ensures the freshness of the leaves, but also effectively prevents the problem of mold caused by accumulated air.

[0082] Please refer again Figures 5 and 6 、 Figure 12 The fresh-keeping component 40 further includes an observation slot 44, which is located in the middle of the main body 10 and outside the water tank 41, and a scale bar is provided in the observation slot 44;

[0083] The manifold 43 is composed of four pipes including three groups of outlet pipes and one group of inlet pipes, and the three groups of outlets of the manifold 43 are respectively connected to the outer circles of the middle sections of the three groups of intake pipes 31 .

[0084] It should be noted that the portion of the manifold 43 communicating with the air inlet pipe 31 is provided with an atomizing nozzle, which is intended to allow the liquid in the water tank 41 to form a mist when entering the air inlet pipe 31, so as to facilitate contact with the indigo leaves in the storage box 21;

[0085] The liquid stored in the water tank 41 is a liquid containing vitamin C, the base is deionized water, and the specific proportions of the remaining materials are:

[0086] Ascorbic acid 0.3% to 0.5% (antioxidant, inhibits polyphenol oxidase activity)

[0087] Citric acid 0.1% to 0.2% (to adjust pH and provide antioxidant benefits)

[0088] Calcium chloride 0.05% to 0.1% (to maintain cell wall structure and enhance toughness);

[0089] The water tank 41 is made of a transparent material, and a transparent isolation plate is fixedly connected to the observation slot 44. The transparent material should be a food-grade transparent material, such as food-grade PP, PC, ABS, PVC, or borosilicate glass. In this embodiment, food-grade PC is preferably used. This allows the remaining water content in the water tank 41 to be observed through the observation slot 44.

[0090] An inlet is formed at the upper end of the water tank 41 and is located in the middle of the main body 10 . A sealing plug is movably inserted into the inlet.

[0091] In this embodiment, when liquid is needed to maintain the freshness of the leaves during use, a water pump 42 draws liquid from the water tank 41. The liquid then enters the air intake pipe 31 through the atomizing nozzle of the manifold 43, forming a fine mist. This mist is blown into the storage box 21 along with the cold air and evenly sprayed on the surface of the indigo leaves, providing them with necessary nutrients and moisturizing properties, helping to maintain their flexibility and freshness. Furthermore, because the water tank 41 is made of a transparent material and has a scale bar on the observation slot 44, the user can intuitively understand the remaining water content in the water tank 41, facilitating timely replenishment of liquid and ensuring the continuous and stable operation of the fresh-keeping cabinet.

[0092] Please refer again Figures 12 to 16 The partition assembly 50 also includes a fixed tube 51, which is fixedly connected to the upper end of the inner cavity of the storage box 21, and the fixed tube 51 is communicated with the connector 36 on the blowing tube 34. The lower end of the fixed tube 51 is provided with four groups of outlets, and the four groups of outlets are all connected to the folding tube 52, and outlets are provided on the front and rear sides of the upper end of the folding tube 52. The bottom end of the inner cavity of the folding tube 52 is fixedly connected to an elastic rope 55, and the upper end of the elastic rope 55 is fixedly connected to the upper end of the inner cavity of the fixed tube 51.

[0093] It should be noted that the foldable tube 52 is made of a soft and foldable material, such as rubber, so that the foldable tube 52 can be pulled and folded by the elastic cord 55 under normal conditions. Only when air is blown into the fixed tube 51 will it expand and leak out of the outlet at the upper end.

[0094] The fixed tube 51 is made of a hard tube and is made entirely of food-grade material, such as 316 stainless steel, so that the fixed tube 51 can stably receive the gas blown out of the blowing tube 34;

[0095] The dividing strip 54 is a blade-shaped plastic structure, which is intended to use the dividing strip 54 to separate the vertically placed leaves so that gas and water mist can cover the surface of the leaves in large quantities, ensuring the uniformity of the fresh-keeping storage of the leaves, and the lower end of the moving process of the dividing strip 54 is higher than the height of the upper end of the limiting plate 38, so as to avoid the dividing strip 54 hindering the position adjustment of the limiting plate 38.

[0096] Preferably, in order to prevent the water mist in the fixed tube 51 from accumulating for a long time and causing mildew, the fixed tube 51 should be configured as a detachable structure to facilitate subsequent cleaning and maintenance.

[0097] In this embodiment, when gas enters the fixed tube 51 through the air blowing pipe 34 and the connector 36, the gas pushes the folding tube 52 to expand. The expansion of the folding tube 52 further pushes the lifting plate 53 and the dividing bar 54 down, separating the vertically placed indigo leaves. In this way, when the cold air carrying water mist blows into the storage box 21 through the fixed tube 51 and the folding tube 52, the gas and water mist can more evenly cover the surface of each indigo leaf, ensuring that the leaves can be evenly preserved and stored. At the same time, because the folding tube 52 is made of a soft and foldable material, when the gas stops blowing, the folding tube 52 will automatically fold under the tension of the elastic cord 55, saving storage space and keeping the interior of the device tidy.

[0098] The present invention works as follows: Indigo leaves with different storage requirements are placed separately on a storage plate 15 in the fresh-keeping area 13 and in a sealed box 17 in the sealed area 14. The storage plate 15 in the fresh-keeping area 13 is designed for storing relatively dry leaves, and a water collection cover 16 at the lower end effectively collects any condensed water droplets. Within the sealed box 17 in the sealed area 14, a filter plate 18 further filters and collects excess liquid. During use, a stop plate 38 is inserted into the appropriate guide rail 37 based on the number of leaves to be stored. After the leaves are placed in the storage box 21, an air intake pipe 31 delivers cold air into the storage box 21. This cold air then flows through a three-pronged pipe 33 into the air blow pipe 34 and the storage chamber, cooling and preserving the leaves. The air intake pipe 35 extracts the accumulated air in the storage chamber through a connector 36, which is then discharged through an air outlet pipe 32, achieving ventilation. At the same time, when the gas enters the fixed tube 51 through the air blowing pipe 34 and the connector 36, the gas will push the folding tube 52 to expand, push the lifting plate 53 and the dividing strip 54 to descend, and separate the vertically placed indigo leaves. Like this, when the cold air carries the water mist and blows into the storage box 21 through the fixed tube 51 and the folding tube 52, the gas and the water mist can more evenly cover the surface of each indigo leaf, ensuring that the blade can be evenly stored in a fresh-keeping manner. If it is necessary to spray the liquid on the blade to keep it fresh, the water pump 42 extracts the liquid from the water tank 41, and then the liquid enters the air inlet pipe 31 through the atomizing nozzle of the manifold 43. These water mists are blown into the storage box 21 together with the cold air and are evenly sprayed on the surface of the indigo leaves, providing necessary nutrients and moisturizing effect for the indigo leaves, helping to keep them flexible and fresh.

[0099] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
