Description

Technical Field

[0001] The invention belongs to the technical field of seasoning preservation, and particularly relates to a device and method for packaging and sealing bags of fresh green peppercorns. Background Art

[0002] Green peppercorns have the effects of aromatic stomachic, warming the middle and dispelling cold, removing dampness and relieving pain, killing insects and detoxifying, relieving itching and removing fishy smell. They can eliminate the fishy smell of various meats; promote saliva secretion, increase appetite; dilate blood vessels, and thus play a role in lowering blood pressure. Fresh green peppercorns are difficult to preserve due to their high water content, and they are also prone to deterioration during long-distance transportation. The taste and color of fresh green peppercorns will also change due to climate, environment and other factors. High concentrations of carbon dioxide can inhibit the respiration of plants and extend the shelf life of green peppercorns.

[0003] In order to extend the shelf life of green peppercorns, carbon dioxide is filled into the packaging bag during packaging. Currently, two packaging devices are used. One is to fill the packaging bag with carbon dioxide in advance and then put the green peppercorns in. However, this will cause air to mix into the packaging bag when the green peppercorns are put in, reducing the concentration of carbon dioxide. Another method is to keep flushing carbon dioxide into the packaging bag. Although the carbon dioxide concentration in the packaging bag is guaranteed, carbon dioxide continues to be supplied when the packaging bag is replaced, resulting in a waste of carbon dioxide. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a fresh green pepper packaging and sealing device and method, which can ensure that there is a high concentration of carbon dioxide in the packaging bag and stop supplying carbon dioxide when the packaging bag is replaced.

[0005] The technical solution of the present invention includes a conveying component and a packaging component. The packaging component includes a sealer, a transmission component and a gas supply device. The packaging bag is placed at the sealing position of the sealer. The sealer is connected to the transmission component, and the transmission component is connected to the gas supply device. The gas supply device is used to inject carbon dioxide into the packaging bag. The opening or closing of the sealer drives the transmission component to move, thereby causing the transmission component to open or close the gas supply device. The conveying component conveys the green pepper to be packaged into the packaging bag.

[0006] Furthermore, the transmission assembly includes a rack and a gear, the gas supply device includes an air supply pipe, a valve is provided on the air supply pipe, the gear is connected to the valve, the rotation of the gear drives the valve to open or close, the rack is connected to the sealer, and the rack and the gear are meshed for transmission. When the sealer is closed to seal the packaging bag, the sealer drives the gear to rotate through the rack, and the rotation of the gear drives the valve to close, preventing the gas supply device from injecting carbon dioxide into the packaging bag. When the sealing is completed, the sealer is opened, and the sealer drives the gear to rotate through the rack, and the rotation of the gear drives the valve to open, so that the gas supply device injects carbon dioxide into the new packaging bag.

[0007] Furthermore, the conveying component includes a conveyor belt, which is used to convey the cleaned green peppercorns into the packaging bag.

[0008] Furthermore, the packaging component is also provided with a weighing device, which is used to weigh the weight of the green peppercorns in the packaging bag. The weighing device is connected to the conveying component and the sealer respectively. The conveying component controls whether to convey the green peppercorns into the packaging bag according to the weight of the green peppercorns on the weighing device, and the sealer controls whether to seal the packaging bag according to the weight of the green peppercorns on the weighing device.

[0009] Furthermore, a drying device is provided on the conveyor belt, and the drying device is used to remove moisture from the green pepper.

[0010] Furthermore, the conveyor belt at the corresponding position of the drying device is arranged as a spiral structure.

[0011] Furthermore, a spraying device is provided on the conveyor belt, and the spraying device is located upstream of the drying device. The spraying device is used to spray salt water onto the cleaned green peppercorns.

[0012] Furthermore, the belt body of the conveyor belt is a mesh structure.

[0013] Furthermore, a funnel is provided above the packaging bag, and the funnel is located below the conveyor belt, and the funnel prevents the green peppercorns from falling out of the packaging bag.

[0014] The present invention also provides a method for packaging and sealing fresh green pepper, comprising the following steps:

[0015] S1: removing impurities from the picked green peppercorns and washing them to preliminarily remove moisture from the green peppercorns;

[0016] S2: The green peppercorns from which water has been initially removed are placed on a conveyor belt, and the conveyor belt transports the green peppercorns into packaging bags;

[0017] S3: The sealing device closes the bag. The sealing device drives the gear to rotate through the rack. The gear rotation drives the valve to close, preventing the gas supply device from injecting carbon dioxide into the packaging bag. Finally, the sealing device seals the green pepper in the packaging bag.

[0018] The technical solution provided by the embodiment of the present invention has the following advantages compared with the prior art: the present invention injects carbon dioxide into the packaging bag through a gas supply device to expel the air in the packaging bag, and then turns off the gas supply device through a transmission assembly when the sealer is closed, so that the gas supply device stops supplying carbon dioxide when the sealer is sealing, and finally the packaging bag is sealed. Compared with the prior art, the present invention can ensure that there is a high concentration of carbon dioxide in the packaging bag, and at the same time stop the supply of carbon dioxide when sealing.

[0019] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0026] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In the description of the embodiments of the present invention, unless otherwise specified, “plurality” means two or more.

[0028] like Figure 1 and Figure 2As shown, the present invention provides a fresh green pepper packaging and sealing device, comprising a conveying component and a packaging component, the packaging component comprising a sealer 1, a transmission assembly and a gas supply device, the packaging bag 2 is placed in the sealing position of the sealer 1, the sealer 1 is connected to the transmission assembly, the transmission assembly is connected to the gas supply device, the gas supply device is used to inject carbon dioxide into the packaging bag 2, the sealer 1 is opened or closed to drive the transmission assembly to move, so that the transmission assembly opens or closes the gas supply device, and the conveying component conveys the green pepper to be packaged into the packaging bag 2.

[0029] The present invention injects carbon dioxide into the packaging bag 2 through a gas supply device to discharge the air in the packaging bag 2, and then turns off the gas supply device through a transmission component when the sealer 1 is closed, so that the gas supply device stops supplying carbon dioxide when the sealer 1 is sealing, and finally the packaging bag is sealed. Compared with the prior art, the present invention can ensure that there is a high concentration of carbon dioxide in the packaging bag and stop the supply of carbon dioxide when sealing.

[0030] It is understandable that high concentrations of carbon dioxide can inhibit plant respiration and slow down plant metabolism, thereby extending the shelf life of green peppercorns.

[0031] It can be understood that the packaging bag 2 is transported to the location of the sealer 1 by existing mature devices, and no further description is given here.

[0032] In the embodiment provided by the present invention, the transmission assembly includes a rack 3 and a gear 4, the gas supply device includes an air supply pipe 6, a valve 5 is provided on the air supply pipe 6, the gear 4 is connected to the valve 5, the rotation of the gear 4 drives the valve 5 to open or close, the rack 3 is connected to the sealer 1, and the rack 3 and the gear 4 are meshed for transmission. When the sealer 1 is closed to seal the packaging bag 2, the sealer 1 drives the gear 4 to rotate through the rack 3, and the rotation of the gear 4 drives the valve 5 to close, preventing the gas supply device from injecting carbon dioxide into the packaging bag 2. When the sealing is completed, the sealer 1 is opened, and the sealer 1 drives the gear 4 to rotate through the rack 3, and the rotation of the gear 4 drives the valve 5 to open, so that the gas supply device injects carbon dioxide into the new packaging bag 2.

[0033] Optionally, the conveying component includes a conveyor belt 7, and the conveyor belt 7 is used to convey the cleaned green peppercorns into the packaging bag 2.

[0034] The optional packaging component is also provided with a weighing device 8, which is used to weigh the weight of the green peppercorns in the packaging bag 2. The weighing device 8 is connected to the conveying component and the sealer 1 respectively. The conveying component controls whether to convey the green peppercorns into the packaging bag 2 according to the weight of the green peppercorns on the weighing device 8, and the sealer 1 controls whether to seal the packaging bag 2 according to the weight of the green peppercorns on the weighing device 8.

[0035] It can be understood that when the first packaging bag 2 is located below the sealer 1, the gas supply device injects carbon dioxide into the packaging bag 2, and the conveyor belt 7 transports green peppercorns into the packaging bag 2. When the green peppercorns weighed by the weighing device 8 reach a certain weight, the conveyor belt 7 stops transporting green peppercorns into the packaging bag 2 according to the weight feedback of the weighing device 8. At the same time, the sealer 1 closes and seals the packaging bag 2 according to the weight feedback of the weighing device 8. During the closing process of the sealer 1, the gear 4 is driven to rotate by the rack 3, and the rotation of the gear 4 drives the valve 5 to close, gradually reducing the injection of carbon dioxide until the injection is completely stopped to avoid unnecessary waste of carbon dioxide. When the packaging is completed, the sealer 1 is opened, the packaging bag 2 is removed, and the new packaging bag 2 is located below the sealer 1 to achieve automatic packaging.

[0036] In the embodiment provided by the present invention, a drying device 9 is provided on the conveyor belt 7, and the drying device 9 is used to remove moisture from the green pepper.

[0037] It is understandable that the surface of the cleaned green pepper has moisture, which can easily cause the green pepper to deteriorate and be damaged if it is directly packaged. Therefore, the moisture on the green pepper is dried by the drying device 9, which helps to extend the shelf life of the green pepper.

[0038] In the embodiment provided by the present invention, the conveyor belt 7 at the corresponding position of the drying device 9 is configured as a spiral structure.

[0039] It can be understood that in order to extend the drying time of the green peppercorns, the residence time of the green peppercorns in the drying device 9 is extended by providing a spiral structure, thereby further ensuring that the moisture on the surface of the green peppercorns is removed.

[0040] In the embodiment provided by the present invention, a spraying device 10 is provided on the conveyor belt 7. The spraying device 10 is located upstream of the drying device 9. The spraying device 10 is used to spray salt water onto the washed green pepper.

[0041] It can be understood that although the green pepper is cleaned, it still carries some bacteria. If the bacteria are not inhibited, the bacterial growth will easily cause the green pepper to deteriorate. Salt has a certain inhibitory effect and is harmless to the human body. By spraying salt water, the surface of the green pepper is covered with salt water, and the moisture is removed by the drying device 9, leaving the salt on the surface of the green pepper, thereby inhibiting the growth of bacteria and further extending the shelf life of the green pepper.

[0042] Furthermore, salt can also prevent the color of green pepper from changing. The principle is: in vegetables, chlorophyll will combine with metal ions to form chlorophyll-metal complexes, and these metal ions can affect the color stability of chlorophyll. After adding salt, the sodium ions in the salt will combine with chlorophyll to form a sodium chlorophyll complex. This complex can make the color of chlorophyll brighter and more stable, and less susceptible to light or oxidation.

[0043] In the embodiment provided by the present invention, the belt body of the conveyor belt 7 is a mesh structure.

[0044] It can be understood that the washed green pepper carries moisture, and the belt body is set as a mesh structure in order to discharge the water under the action of gravity to avoid accumulation on the conveyor belt, so that the drying device 9 can quickly remove the moisture on the surface of the green pepper.

[0045] In the embodiment provided by the present invention, a funnel 11 is provided above the packaging bag 2 , and the funnel 11 is located below the conveyor belt 7 , and the funnel 11 prevents the green peppercorns from falling out of the packaging bag 2 .

[0046] The present invention also provides a method for packaging and sealing fresh green pepper, comprising the following steps:

[0047] S1: removing impurities from the picked green peppercorns and washing them to preliminarily remove moisture from the green peppercorns;

[0048] S2: placing the green peppercorns from which water has been initially removed on a conveyor belt 7, and the conveyor belt 7 transports the green peppercorns into packaging bags;

[0049] S3: During the closing process of the sealer 1, the sealer 1 drives the gear 4 to rotate through the rack 3, and the rotation of the gear 4 drives the valve 5 to close, thereby preventing the gas supply device from injecting carbon dioxide into the packaging bag 2. Finally, the sealer 1 seals the green pepper in the packaging bag 2.

[0050] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0051] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
