Description

Technical Field

[0001] The present invention belongs to the technical field of fresh-keeping technology of Zongruo leaves, and particularly relates to a fresh-keeping cabinet for Zongruo leaves. Background Art

[0002] As the core raw material for making traditional zongzi, the freshness and quality of Zongruo leaves (Indocalamus leaves) directly affect the flavor, color and food safety of zongzi. However, the existing fresh-keeping technologies are difficult to meet the stringent requirements of high-activity preservation, mold and bacteria inhibition, and classification management after the leaves are picked, resulting in a relatively high raw material loss rate.

[0003] Specifically, first, after fresh leaves are picked, they still have metabolic activity. Although a conventional cold storage (2-4°C) can delay spoilage, low-temperature stress causes two major problems: 1. Long-term refrigeration causes lipid peroxidation of cell membranes, resulting in leaf dehydration and shrinkage, and the zongzi wrapping is prone to cracking; 2. Low temperature inhibits enzyme activity, resulting in the disassembly of the chlorophyll-protein complex, resulting in an increase in the leaf yellowing index and the loss of the emerald green appearance.

[0004] Secondly, the waxy layer on the surface of the leaves is prone to dew condensation when cold. However, when too much liquid accumulates on the leaves, it is easy to breed toxin-producing fungi such as Aspergillus niger and Penicillium. And the condensed water accumulates in the vein grooves. These liquids will dissolve the polysaccharides on the leaves to form mucus, which is easy to accelerate the decay of the leaves and produce a fishy smell. Summary of the Invention

[0005] The purpose of the present invention is to provide a fresh-keeping cabinet for Zongruo leaves, which can place different Zongruo leaves in different storage environments according to the storage requirements of the leaves, and can also spray an appropriate amount of liquid on the leaves according to the needs when delivering cold air to keep the leaves fresh, and can use the blowing gas to separate the stacked leaves when delivering cold air and water mist, so that the leaves can evenly receive cold air and water mist for fresh-keeping.

The outlet end of the converging pipe penetrates through the main body and is located outside the main body, and a valve is fixedly connected to the outer ring of the part where the converging pipe extends out of the main body.

[0011] In a preferred solution, the ventilation component further includes three air outlet pipes.

[0012] In a preferred solution, four storage cavities for storing Indocalamus leaves are opened in the inner cavity of the storage box, and a maintenance cavity for placing pipelines is opened in the part of the inner cavity of the storage box other than the storage cavities. The air blowing pipe and the air suction pipe are both fixedly connected in the maintenance cavity, and the inlets and outlets of the air blowing pipe and the air suction pipe both extend into the storage cavity and are fixedly connected with connectors. And the air blowing pipe and the air suction pipe are both provided with two groups, which are respectively communicated with the two ports of the three-way pipe. Two guide rails are fixedly connected to the lower side of the inner cavity of the storage cavity, and a limiting plate is slidably connected in the inner cavity of one of the guide rails.

[0013] In a preferred solution, the fresh-keeping component further includes an observation groove, which is opened at the position of the middle part of the main body outside the water tank, and a scale bar is arranged in the observation groove.

[0014] In a preferred embodiment, the multi-head pipe is composed of three groups of outlet pipes and a four-head pipe at the inlet, and the three outlets of the multi-head pipe are respectively communicated with the outer circumference of the middle section of the three groups of inlet pipes.

An elastic rope is fixedly connected to the bottom end of the inner cavity of the folding pipe, and the upper end of the elastic rope is fixedly connected to the upper end of the inner cavity of the fixed pipe.

[0016] The technical effects achieved by the present invention are as follows: The ice storage area, fresh storage area, sealing area and water filtering component of the present invention can place different Indocalamus leaves in different storage environments according to the needs of leaf storage, and can timely discharge the excess liquid to avoid the decay of leaves and affect the quality; when in use, fresh leaves, dried leaves and pre-steamed leaves are respectively sent into the ice storage area, fresh storage area and sealing area for storage and preservation. And during storage, the excess liquid on the leaves will flow out of the main body along the water receiving plate, avoiding the accumulation of liquid leading to the corruption of leaves and affecting the freshness of the leaves; The air exchange component and fresh preservation component of the present invention can spray an appropriate amount of liquid on the leaves according to the needs when transporting cold air to keep the leaves fresh; when in use, the main body blows air into the blowing pipe through the inlet pipe, and then transports cold air.

[0020] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art may make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0021] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0022] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of illustration, the cross-sectional views showing the device structure are enlarged locally out of proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0023] Please refer to the attached Figures 1 to 2 、 Figures 6 to 7 、 Figures 12 to 15 As shown, this embodiment provides a zongruo leaf fresh-keeping cabinet, including: A main body 10, in which an ice storage area 12, a fresh-keeping area 13, and a sealed area 14 are respectively opened in the inner cavity of the main body 10; A water filtering assembly 20, the water filtering assembly 20 includes a storage box 21, a water receiving plate 23 is movably inserted into the inner cavity of the storage box 21, the water receiving plate 23 is fixedly connected to the inner cavity of the ice storage area 12, and a filtering port 24 is opened above the water receiving plate 23 in the inner cavity of the storage box 21; A ventilation assembly 30, the ventilation assembly 30 includes an air inlet pipe 31, the air inlet pipe 31 is installed at the rear side of the inner cavity of the ice storage area 12, a blowing pipe 34 is installed on one side of the inner cavity of the storage box 21, and the blowing pipe 34 is communicated with the air inlet pipe 31, and an air suction pipe 35 is installed on the other side of the storage box 21; A fresh-keeping assembly 40, the fresh-keeping assembly 40 includes a water tank 41, the water tank 41 is installed in the inner cavity of the main body 10, a water pump 42 is connected to the inner cavity of the main body 10, the inlet of the water pump 42 is communicated with the water tank 41, and the outlet of the water pump 42 is communicated with a multi-head pipe 43, and the multi-head pipe 43 is communicated with the air inlet pipe 31; A partitioning assembly 50, the partitioning assembly 50 includes a folding pipe 52, the lower end of the folding pipe 52 is fixedly connected to a lifting plate 53, and the lower end of the lifting plate 53 is fixedly connected to a plurality of partition strips 54; Among them, the chilled storage area 12, the fresh-keeping storage area 13, and the sealed storage area 14 store Indocalamus leaves with different storage requirements. The air inlet pipe 31 injects cold air into the storage box 21 through the air blowing pipe 34. When the air inlet pipe 31 inputs cold air, 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. When the air blowing pipe 34 accesses gas, the gas blows into the folding pipe 52 to make it expand, pushing the lifting plate 53 and the partition strip 54 down to separate the leaves.

[0024] It should be noted that to ensure the normal use of the device and achieve the effect of discharging excess liquid, when storing Indocalamus leaves, the leaves should be stored upright so that the excess liquid on the leaf surface can be quickly discharged to avoid affecting the storage of the leaves. The main body 10 is an air-cooled refrigeration device as a whole, and is internally provided with a humidity regulation function (such as a fresh air refrigerator with an internal humidity control function). The chilled storage area 12 is used to store fresh leaves, and 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 storage area 13 is used to store dry 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 storage area 14 is used to store the leaves after pre-steaming and sterilization, and its operating temperature should be maintained at about 4 degrees Celsius, and the humidity should be maintained at 50% to 60% RH, thereby inhibiting enzyme activity and avoiding texture softening.

[0025] Preferably, to prevent the dry leaves from getting damp and mildewing, the sealing performance between the fresh-keeping storage area 13 and the sealed storage area 14 should be ensured, and the fresh-keeping storage area 13 needs to be internally provided with a circulating air function (this is a common technical structure in the prior art and will not be elaborated too much here) to prevent the leaves from getting damp and mildewing. The temperature and humidity control in the chilled storage area 12, the fresh-keeping storage area 13, and the sealed storage area 14 should be adjustable according to requirements, so as to cope with different storage scenarios.

[0026] In this embodiment, when in use, the Indocalamus leaves with different preservation requirements are respectively placed in the chilled storage area 12, the fresh-keeping storage area 13, and the sealed storage area 14. Under normal conditions, the air inlet pipe 31 sends cold air into the air blowing pipe 34 and the folding pipe 52. At this time, the folding pipe 52 expands, thereby pushing the lifting plate 53 and the partition strip 54 down. The vertically placed Indocalamus leaves are separated by the partition strip 54, so that air can evenly enter the gaps between the leaves. If it is necessary to spray water mist on the Indocalamus leaves to keep them fresh, the water pump 42 extracts liquid from the water tank 41, and then the liquid forms water mist through the multi-head pipe 43 and is sent into the air inlet pipe 31, so that water mist can be sprayed on the folding pipe 52 to evenly spray the Indocalamus leaves to ensure uniformity. If there is too much accumulated water on the leaf surface, the accumulated water will be discharged through the water receiving plate 23, the sewer pipe 25, and the confluence pipe 26.

[0027] Secondly, please refer to againFigures 1 to 3 , two groups of cabinet doors 11 are hinged to the front of the main body 10. The two groups of cabinet doors 11 respectively cover the outside of the fresh-keeping area 12, the fresh-keeping area 13 and the sealing area 14. Three storage plates 15 are placed in the inner cavity of the fresh-keeping area 13, and two sealing boxes 17 are movably inserted into the inner cavity of the sealing area 14; Water receiving covers 16 are fixedly connected to the lower ends of the three storage plates 15, aiming to prevent the leaves stored in the fresh-keeping area 13 from contacting the humid outside air when the cabinet doors 11 are frequently opened and closed, so as to avoid the accumulation of condensed water droplets on their surfaces, which will affect the storage of the leaves. Filter plates 18 are fixedly connected to the lower ends of the inner cavities of the two sealing boxes 17, and drain openings 19 are provided at the positions below the filter plates 18 on the lower front of the sealing boxes 17.

[0028] It should be noted that a sealing plug is movably inserted into the drain opening 19 to improve the sealing effect.

[0029] Preferably, to ensure convenient use in the future, the water receiving cover 16 should be set as a detachable structure, or a faucet for draining water (a common technical structure in the existing technology, not described in detail here) should be provided at its lower end, aiming to facilitate the drainage of the liquid in the water receiving cover 16.

[0030] In this embodiment, during use, the bamboo leaves with different preservation requirements are respectively placed on the storage plates 15 in the fresh-keeping area 13 and in the sealing boxes 17 in the sealing area 14. The storage plates 15 in the fresh-keeping area 13 are designed to store relatively dry bamboo leaves, and the water receiving covers 16 at their lower ends can effectively collect the possible condensed water droplets, preventing the accumulation of water droplets from affecting the quality of the leaves. In the sealing boxes 17 in the sealing area 14, the filter plates 18 help to further filter and collect the excess liquid, and these liquids can be conveniently discharged through the drain openings 19 to maintain the environment in the sealing area 14, thereby effectively inhibiting the enzyme activity, avoiding texture softening, and ensuring that the leaves after pre-steaming and sterilization can maintain their quality for a long time.

[0031] Secondly, please refer to again Figures 4 to 10 , the water filtering component 20 further includes a box cover 22, and the box cover 22 is movably inserted in the front of the storage box 21; Three downspouts 25 are installed at the rear side of the inner cavity of the fresh-keeping area 12. The inlets of the three downspouts 25 are respectively connected to the outlets of each water receiving plate 23, and the lower ends of the downspouts 25 are all connected to a converging pipe 26. The outlet end of the converging pipe 26 penetrates through the main body 10 and is located outside the main body 10, and a valve 27 is fixedly connected to the outer circle of the part where the converging pipe 26 extends out of the main body 10.

[0032] 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, aiming to enable the liquid falling from the filter opening 24 to directly enter the converging pipe 26 through the water receiving plate 23; A sealing layer is provided at the part where the lid 22 contacts the storage box 21 to improve the sealing effect.

[0033] Preferably, the valve 27 is always in a closed state under normal conditions. Only when the liquid stored in the confluence pipe 26 is higher than the inlet of the lowest drain pipe 25, the valve 27 will open to drain the liquid. In order to ensure that the 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 drain pipe 25, so as to facilitate the detection of the height of the liquid stored in the confluence pipe 26.

[0034] In this embodiment, when too much liquid accumulates on the blades, the liquid falls through the filter port 24 onto the water receiving plate 23, and then flows into the drain pipe 25 through the slope design of the water receiving plate 23. The three drain pipes 25 collect the liquid into the confluence pipe 26. The design of the confluence pipe 26 not only facilitates the unified discharge of excess liquid, but also realizes the precise control of the discharge timing through the control of the valve 27, effectively avoiding the problem of blade corruption caused by liquid accumulation. When the liquid in the confluence pipe 26 accumulates to a certain extent, the liquid level sensor will send a signal to prompt the operator to open the valve 27 for discharge, ensuring the continuous optimization of the internal environment of the fresh-keeping cabinet.

[0035] Secondly, please refer to again Figure 5 、 Figures 11 to 15 The ventilation assembly 30 further includes three air outlet pipes 32. The three air outlet pipes 32 are all fixedly installed at 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 pipes 32 both extend into the storage box 21 and are both connected to a three-headed pipe 33. The other two ends of the two three-headed pipes 33 are respectively connected to a blowing pipe 34 and a suction pipe 35; Four storage cavities for storing bamboo leaves are provided in the inner cavity of the storage box 21. And a maintenance cavity for placing pipelines is provided in the part of the inner cavity of the storage box 21 outside the storage cavities. The blowing pipe 34 and the suction pipe 35 are both fixedly connected in the maintenance cavity. The inlets and outlets of the blowing pipe 34 and the suction pipe 35 both extend into the storage cavity and are fixedly connected with a connector 36. And the blowing pipe 34 and the suction pipe 35 are both provided with two groups, which are respectively connected to the two ports of the three-headed pipe 33. Two guide rails 37 are fixedly connected to the lower side of the inner cavity of the storage cavity. And a limiting plate 38 is slidably connected in the inner cavity of one of the guide rails 37.

[0036] It should be noted that the air inlet pipe 31 and the air outlet pipes 32 are respectively connected to the air-cooling system in the main body 10, aiming to use the air inlet pipe 31 to convey cold air into the storage box 21 and suck out the accumulated gas through the air outlet pipes 32 to achieve the effect of ventilation; A through groove is provided on the surface of the limiting plate 38 to prevent the limiting plate 38 from affecting the extraction of gas by the connector 36 connected to the suction pipe 35; One side of the limiting plate 38 close to the air blowing pipe 34 is provided with a slope, aiming to enable the bamboo leaves to lean against the limiting plate 38 obliquely, avoiding the situation where the number of stored bamboo leaves is insufficient for vertical placement and affecting the water drainage effect; Metal meshes are fixedly connected to the parts of the connecting head 36 extending into the storage cavity. While improving the gas flow stability, the water mist blown out by the air blowing pipe 34 can be further refined; A magnetic attraction plate is fixedly connected to the lower end of the limiting plate 38, and a matching magnetic attraction component is also installed at the lower end of the inner cavity of the guide rail 37, so that the limiting plate 38 can be fixed in the inner cavity of the guide rail 37.

[0037] In this embodiment, during use, according to the number of leaves to be stored, the limiting plate 38 is inserted into a suitable guide rail 37. After the leaves are placed in the storage box 21, the air inlet pipe 31 conveys cold air into the storage box 21, and the cold air enters the air blowing pipe 34 through the three-way pipe 33. The air blowing pipe 34 blows the cold air into the storage cavity to cool and preserve the bamboo leaves. The air suction pipe 35 extracts the accumulated gas in the storage cavity through the connecting head 36, and these gases are then discharged through the air outlet pipe 32 to achieve the air exchange effect. Such a design not only ensures the freshness of the bamboo leaves but also effectively avoids the mildew problem caused by the accumulated gas.

[0038] Please refer to again Figures 5 to 6 、 Figure 12 The freshness preservation component 40 further includes an observation slot 44. The observation slot 44 is opened at a position in the middle of the main body 10 outside the water tank 41, and a scale bar is arranged in the observation slot 44; The multi-head pipe 43 is composed of a four-head pipe with three outlet pipes and one inlet pipe, and the three outlets of the multi-head pipe 43 are respectively communicated with the outer circles of the middle sections of the three air inlet pipes 31.

[0039] It should be noted that atomizing nozzles are arranged at the parts where the multi-head pipe 43 is communicated with the air inlet pipe 31, aiming to enable the liquid in the water tank 41 to form water mist when entering the air inlet pipe 31, which is convenient for contacting the bamboo leaves in the storage box 21; The liquid stored in the water tank 41 is a liquid containing vitamin C, with the base being deionized water, and the specific ratio of the remaining materials is as follows: Ascorbic acid 0.3% to 0.5% (antioxidant, inhibiting the activity of polyphenol oxidase) Citric acid 0.1% to 0.2% (adjusting the pH value, synergistic antioxidant) Calcium chloride 0.05% to 0.1% (maintaining the cell wall structure and enhancing toughness); The water tank 41 is made of a transparent material, and a transparent partition board is also fixedly connected in the observation slot 44. The transparent material should be a food-grade transparent material, such as food-grade PP, PC, ABS, PVC, and borosilicate glass. In this embodiment, it is preferably made of food-grade PC material, aiming to be able to observe the remaining water content in the water tank 41 through the observation slot 44; An inlet is opened at the upper end of the water tank 41, and the inlet is located in the middle of the main body 10. A sealing plug is movably inserted into the inlet.

[0040] In this embodiment, when it is necessary to spray liquid on the leaves to keep them fresh during use, the water pump 42 extracts the liquid from the water tank 41. Subsequently, the liquid enters the air inlet pipe 31 through the atomizing nozzles of the multi-head pipe 43, and then forms fine water mist. These water mists are blown into the storage box 21 together with the cold air and evenly sprayed on the surface of the bamboo leaves, providing necessary nutrients and moisturizing effects for the bamboo leaves, and helping to keep them flexible and fresh. At the same time, since the water tank 41 is made of a transparent material and a scale bar is set through the observation slot 44, users can intuitively understand the remaining water content in the water tank 41, which is convenient for timely replenishing the liquid and ensuring the continuous and stable operation of the fresh-keeping cabinet.

[0041] Please refer to again Figures 12 to 16 , the partition component 50 further includes a fixed pipe 51. The fixed pipe 51 is fixedly connected to the upper end of the inner cavity of the storage box 21, and the fixed pipe 51 is communicated with the connector 36 on the air blowing pipe 34. Four groups of outlets are opened at the lower end of the fixed pipe 51. Folding pipes 52 are communicated in all four groups of outlets. The upper end of the folding pipe 52 is provided with outlets on the front and rear sides. A elastic rope 55 is fixedly connected to the bottom end of the inner cavity of the folding pipe 52, and the upper end of the elastic rope 55 is fixedly connected to the upper end of the inner cavity of the fixed pipe 51.

[0042] It should be noted that the folding pipe 52 is made of a soft and foldable material, such as rubber, aiming to make the folding pipe 52 be pulled and folded by the elastic rope 55 under normal conditions, and only when air is blown in the fixed pipe 51, it will expand to expose the upper outlet; The fixed pipe 51 is made of a hard pipe material and is a food-grade material as a whole, such as 316 stainless steel, aiming to enable the fixed pipe 51 to stably receive the gas blown out by the air blowing pipe 34; The partition strip 54 is a blade-type plastic structure, aiming to use the partition 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 storage of the leaves, and the lowest end of the moving process of the partition strip 54 is higher than the upper end of the limiting plate 38, avoiding the partition strip 54 from hindering the position adjustment of the limiting plate 38.

[0043] Preferably, in order to avoid the long-term accumulation of water mist in the fixed pipe 51 resulting in mildew, the fixed pipe 51 should be set as a detachable structure for subsequent cleaning and maintenance.

[0044] In this embodiment, when the gas enters the fixed tube 51 through the blow tube 34 and the connector 36, the gas will push the folding tube 52 to unfold. The unfolding of the folding tube 52 further pushes the lifting plate 53 and the partition strip 54 downward, separating the vertically placed bamboo leaves. In this way, when the cold air carrying water mist is blown 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 bamboo leaf, ensuring that the leaves can be evenly stored in a fresh state. At the same time, since the folding tube 52 is made of a soft and foldable material, when the gas stops being blown in, the folding tube 52 will automatically fold under the pulling force of the elastic cord 55, saving storage space and keeping the interior of the device clean.

[0045] The working principle of the present invention is as follows: Bamboo leaves with different preservation requirements are respectively placed on the storage plate 15 in the fresh-keeping area 13 and in the sealed box 17 in the sealed area 14. The storage plate 15 in the fresh-keeping area 13 is designed to store relatively dry bamboo leaves, and the water receiving cover 16 at the lower end can effectively collect the possibly condensed water droplets. In the sealed box 17 in the sealed area 14, the filter plate 18 helps to further filter and collect the excess liquid. When in use, according to the number of leaves to be stored, the limiting plate 38 is inserted into the appropriate guide rail 37. After the leaves are placed in the storage box 21, the air inlet pipe 31 conveys cold air into the storage box 21. The cold air enters the blow tube 34 and the storage cavity through the three-way tube 33 to cool and preserve the bamboo leaves. The suction pipe 35 extracts the accumulated gas in the storage cavity through the connector 36, and these gases are then discharged through the air outlet pipe 32 to achieve the ventilation effect. At the same time, when the gas enters the fixed tube 51 through the blow tube 34 and the connector 36, the gas will push the folding tube 52 to unfold, pushing the lifting plate 53 and the partition strip 54 downward, separating the vertically placed bamboo leaves. In this way, when the cold air carrying water mist is blown 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 bamboo leaf, ensuring that the leaves can be evenly stored in a fresh state. When it is necessary to spray liquid on the leaves to keep them 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 multi-head tube 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 bamboo leaves, providing the necessary nutrients and moisture retention effect for the bamboo leaves, and helping to keep them flexible and fresh.

[0046] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special instructions and limitations.
