Description

Technical Field

[0001] The present invention relates to packaging equipment, in particular to deoxidizer packaging equipment and a packaging method. Background Art

[0002] Food spoilage is caused by oxidation and the growth of microorganisms such as mold, bacteria, yeast, and insects. Food oxidation is directly caused by oxygen, and the growth of microorganisms and insects is closely related to oxygen. To prevent food spoilage and oxidation and eliminate the effects of oxygen on food, manufacturers often use methods such as vacuum packaging, gas displacement packaging, packaging with deoxidizers, and the addition of antioxidants. Among these methods, using deoxidizers within the packaging to remove oxygen offers advantages over vacuum and gas displacement packaging: it not only removes oxygen within the package, but also removes oxygen that penetrates through the packaging film and oxygen dissolved in solid, powdered, and liquid foods. It also maintains the food's appearance. Unlike additives, deoxidizers do not come into direct contact with the food and do not alter its flavor, leading to their widespread use in various food packaging applications.

[0003] Currently, iron-based deoxidizers are the most popular type of deoxidizer. These deoxidizers are composed of iron powder with carbon powder as an oxidation catalyst. Reduced iron reacts with oxygen in the air to produce ferric oxide, which absorbs oxygen and reduces the oxygen concentration in the gas. Most deoxidizers currently used on the market are based on this chemical principle. Existing technology incorporates water, water-retaining agents such as absorbent resins, and metal salts into the deoxidizer formulation to accelerate the iron powder's oxidation rate and control the oxygen absorption process, thereby achieving optimal quality preservation. However, before packaging and encapsulation, the deoxidizer material is exposed to the air in a dispersed state, leaving a large area of ​​direct contact with air. This accelerated deoxidation also accelerates the loss of the iron powder's oxygen absorption capacity. Furthermore, the fine particles in this dispersed state are easily dispersed into the air, increasing losses and significantly impacting the production environment. More seriously, when dust falls into the bag, it can easily contaminate the edge seals of the packaging film, leading to quality issues such as material jamming and leaks.

[0004] The oxidation loss of deoxidizer materials when in contact with air mainly occurs during the mixing process and during the transportation, metering, unloading and packaging processes after mixing. As long as the mixing container is sufficiently sealed and in contact with air, the problem is easy to solve. However, the transportation, metering, unloading and packaging processes after mixing are more problematic. The application number is 2020107574784, and the name is a quantitative discharging and packaging device for bagged deoxidizer with good sealing performance. It provides a quantitative discharging and packaging device for bagged deoxidizer with good sealing performance. The quantitative discharging and packaging device for bagged deoxidizer with good sealing performance is composed of four major mechanisms: a quantitative discharging mechanism, a material guiding mechanism, a sealing packaging mechanism and a sealing dust-proof mechanism. The notched scraper, the material blocking column and the material guiding scraper structure design of the quantitative discharging mechanism can make the deoxidizer powder in the material tray filled into the discharging hole. At the same time, the opening and closing components can make the discharging hole a quantitative container for the deoxidizer powder, and the deoxidizer discharged into the packaging bag each time is quantitative, realizing automatic discharging and automatic opening of the discharging hole, and then the sealing piece automatically blocks the lower hole of the discharging hole. The degree of automation is high, and the quantitative method of volume is used to make the quantitative more standard, the error is smaller, and the accuracy is higher.

[0005] Although the improvement of the above-mentioned device solves the problem of quantitative bagging of dispersed deoxidizers with a quantitative discharging mechanism with good sealing performance, it does not solve the problem of dust dispersion during the discharging process, nor does it avoid the oxidation loss of dispersed deoxidizer materials when they come into contact with air and the quality accidents of leakage caused by the material being clamped. In order to avoid the oxidation loss of dispersed deoxidizer materials when they come into contact with air and the quality accidents of leakage caused by the material being clamped, the existing technology also makes the deoxidizer materials into granules or presses them into sheets before packaging; for example, patents with application numbers: 2023110800727, 2021113888800 and 2025101509093, which are made by making the deoxidizer materials into granules or pressing them into sheets before packaging. Although this technology can solve the quality problems of oxidation loss of deoxidizer materials when in contact with air and leakage of materials, the dispersed deoxidizer materials need to be granulated with a binder. The binder makes the iron powder stick together after packaging, which affects the deoxidation capacity. In addition, special equipment and processes are required to press the deoxidizer materials into sheets before packaging, which increases equipment investment and production costs. Summary of the Invention

[0006] The purpose of the present invention is to provide a deoxidizer packaging device, which can avoid oxidation loss caused by contact of dispersed deoxidizer materials with air, prevent quality accidents such as material clamping and leakage, and solve the problem of decreased deoxidation capacity caused by granulation or tableting of deoxidizer materials, thereby reducing production costs.

[0007] Another object of the present invention is to provide a deoxidizer packaging method, which can avoid oxidation loss caused by contact of dispersed deoxidizer materials with air, prevent quality accidents such as material clamping and leakage, and solve the problem of decreased deoxidation capacity caused by granulation or tableting of deoxidizer materials, thereby reducing production costs.

[0008] In order to achieve the above-mentioned purpose, the deoxidizer packaging equipment provided by the present invention includes a sealed feeding container, a feeding pipe, a compression device, a refrigeration device, a forming tube and a metering pressing device, the feeding pipe has a through hole passing through both ends and a feeding port is provided on one side; the output end of the sealed feeding container is connected with the feeding port to provide powdered deoxidizer; the compression device is arranged at one end of the feeding pipe to squeeze the deoxidizer in the through hole and transport it to the other end of the feeding pipe; the other end of the feeding pipe is connected with the input end of the forming tube; the refrigeration device is arranged on the outside of the feeding pipe and freezes the feeding pipe so that the deoxidizer forms a frozen strip; a feeding hole is provided on one side of the forming tube, and the metering pressing device is arranged on the forming tube and presses the frozen strip out of the feeding hole in a quantitative manner. Compared with the prior art, the present invention is connected to a sealed blanking container through a feeding pipe, so that the powdered deoxidizer can automatically fall into the feeding pipe, and then the deoxidizer in the feeding pipe is compressed and transported forward by a compression device. At the same time, the compressed deoxidizer is frozen by a refrigeration device, so that the deoxidizer forms a frozen material strip, and finally the metering pressing device on the forming tube is quantitatively cut and blanked. The whole process is carried out in a sealed container and a tube, which greatly reduces the contact of the deoxidizer with the air. Moreover, by freezing the deoxidizer from a dispersed state into a solid state, the dispersed deoxidizer material is prevented from contacting with the air and causing oxidation loss. In addition, since the deoxidizer is still in a frozen solid state during blanking, dust will not be generated, and no deoxidizer powder will fall onto the sealed edge of the packaging bag, thus effectively preventing the quality accident of the sandwiched material leaking. Moreover, after packaging, the frozen deoxidizer can be warmed up and restored to a powdered state, avoiding the solid state from causing the deoxidation capacity to decrease, the deoxidation capacity is high, and the production cost is low.

[0009] Preferably, the compression device includes a motor and a screw, with the output end of the motor connected to one end of the screw; the other end of the screw sealably extends from one end of the feed pipe into a through hole and to the other end of the feed pipe to compress and convey the deoxidizer. By using a motor to drive the screw, the screw can both propel the dispersed deoxidizer material forward within the feed pipe to achieve the purpose of conveyance and squeeze the dispersed deoxidizer material together, thereby freezing it into a long solid strip. This method simplifies the equipment and reduces costs.

[0010] Preferably, the refrigeration device includes a freezing jacket and a freezing medium delivery device. The freezing jacket is sleeved over the feed pipe. A medium passage is defined within the freezing jacket around a central axis, and the freezing medium delivery device is in communication with the medium passage. The freezing jacket can be wrapped around the feed pipe, allowing the freezing medium to be delivered to the freezing jacket via the freezing medium delivery device. The freezing medium then refrigerates the feed pipe, thereby freezing the adhesive into a solid state. The structure is simple and compact, and the freezing effect is excellent.

[0011] Preferably, the deoxidizer packaging equipment further includes a sealed recovery container in communication with the output end of the forming tube. Since the metering and pressing device generates excess material each time it cuts the material, the provision of a sealed recovery container allows the excess material to be completely recycled and reused, thus avoiding waste. Furthermore, the excess material is contained within a sealed space during recycling, significantly reducing the possibility of oxidation from contact with air and thus not affecting the quality of the deoxidizer.

[0012] Preferably, the deoxidizer packaging equipment further comprises a packaging machine, wherein the feed hole is connected to an inlet of the packaging machine, and the packaging machine bags the frozen block deoxidizer. By connecting the feed hole to the inlet of the packaging machine, the frozen deoxidizer can be directly packaged and sealed, thereby significantly reducing contact with air and preventing a decrease in the deoxidizer's deoxidation capacity.

[0013] Preferably, the metering and pressing device includes a metering and pressing element, a pressing rod, and a driving device. The metering and pressing element is disposed at one end of the pressing rod, and the driving device is connected to the other end of the pressing rod to drive the metering and pressing element into the forming tube to force a certain amount of frozen deoxidizer out of the discharge hole. By using the driving device and the pressing rod to drive the metering and pressing element, the frozen deoxidizer can be discharged in a quantitative manner, thereby facilitating subsequent packaging operations and improving the automation capabilities of the equipment.

[0014] Specifically, the metering and pressing device further includes a reset spring, the driving device is a pneumatic device, the pneumatic device drives the pressing rod to extend and press the material through air pressure, and the reset spring provides elastic force to reset the pressing rod.

[0015] Specifically, the deoxidizer packaging equipment further includes a mixing tank, the output end of which is connected to the input end of the sealed blanking container, and the recovery end of which is connected to the output end of the sealed recovery container. By providing the mixing tank at the input end of the sealed blanking container, the deoxidizer can be automatically dropped directly into the sealed blanking container after mixing is completed for packaging. Furthermore, the residual material left after packaging can be recovered, achieving automated and continuous operation, effectively improving production efficiency, eliminating waste generation, and contributing to reduced production costs.

[0016] A deoxidizer packaging method comprises the following steps: using a screw to compress and transport the powdered deoxidizer in a conveying pipe; using a refrigeration device to freeze the deoxidizer in the conveying pipe to form frozen strips; using a metering and pressing device to cut the frozen strips into blocks and output them; and using a packaging machine to package the block deoxidizer.

[0017] Preferably, the method further comprises the steps of recovering the remaining material after the frozen material is cut into long strips and returning the material to the temperature for reuse. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural diagram of the deoxidizer packaging equipment of the present invention.

[0019] Figure 2 It is a flow chart of the deoxidizer packaging method of the present invention. DETAILED DESCRIPTION

[0020] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0021] See also Figure 1 The deoxidizer packaging equipment 100 of the present invention includes a sealed feeding container 1, a feeding pipe 2, a compression device 3, a refrigeration device 4, a forming pipe 5 and a metering pressing device 6. The feeding pipe 2 has a through hole 21 running through both ends and a feed port 22 on one side, and the feed port 22 is connected to the through hole 21. The lower end of the sealed feeding container 1 is provided with an output end, and the output end of the sealed feeding container 1 is connected to the feed port 22 to provide powdered deoxidizer. The compression device 3 is arranged at one end of the feeding pipe 2 to squeeze the deoxidizer in the through hole 21 and transport it to the other end of the feeding pipe 2. The other end of the feeding pipe 2 is connected to the input end of the forming pipe 5. The refrigeration device 4 is arranged on the outside of the feeding pipe 2 and freezes the feeding pipe 2 so that the deoxidizer is frozen to form long strips of frozen material. A feeding hole 51 is provided on one side of the forming tube 5. The metering and pressing device 6 is arranged on the forming tube 5 and presses the frozen material strips out of the feeding hole 51 in a fixed quantity. An elastic opening and closing door is provided at the feeding hole 51. When the frozen material strips are cut and fed, the material can push the elastic opening and closing door open, allowing the material to be fed. After the material is fed, the elastic opening and closing door can be reset and closed under the action of the elastic force, thereby preventing air from entering the forming tube 5 through the feeding hole 51.

[0022] For example Figure 1As shown, the compression device 3 includes a motor 31 and a screw 32. The output end of the motor 31 is connected to one end of the screw 32. The other end of the screw 32 extends from one end of the feed pipe 2 into the through hole 21 in a sealed manner and extends to the other end of the feed pipe 2. The rotation of the screw 32 can squeeze and transport the deoxidizer. By using the motor 31 to drive the screw 32, the screw 32 can not only propel the dispersed deoxidizer material forward in the feed pipe 2 to achieve the purpose of transportation, but also squeeze and compress the dispersed deoxidizer material, thereby forming a long solid strip through freezing. The equipment is simple and low in cost.

[0023] See also Figure 1 The refrigeration device 4 includes a freezing jacket 41 and a freezing medium conveying device 42. The freezing jacket 41 is a tubular structure with a central hole along the central axis for the feed pipe 2 to be connected. The freezing jacket 41 is connected to the outside of the feed pipe 2. A medium channel 411 is provided around the central axis within the freezing jacket 41. The medium channel 411 can be spirally arranged around the central axis or arranged parallel to the central axis and circumferentially around the central axis. The freezing medium conveying device 42 is connected to the medium channel 411 to convey a freezing medium to the freezing jacket 41. The freezing medium is a refrigerant with a temperature between -15 degrees and 0 degrees Celsius. The freezing medium undergoes heat exchange in the medium channel 411, thereby freezing the deoxidizer. By wrapping the freezing jacket 41 around the feed pipe 2, the freezing medium is conveyed into the freezing jacket 41 through the freezing medium conveying device 42. The feed pipe 2 is cooled by the freezing medium, thereby freezing the deoxidizer into a solid state. The structure is simple and compact, and the freezing effect is good.

[0024] See also Figure 1 The deoxidizer packaging equipment 100 also includes a sealed recovery container 7, which is connected to the output end of the forming tube 5. Since the metering and pressing device 6 produces residual material each time it cuts and blanks the material, the provision of a sealed recovery container 7 allows all the residual material to be recycled and reused, thus avoiding waste. Moreover, the residual material is also in a sealed space during recycling, greatly reducing the possibility of oxidation due to contact with air, and thus does not affect the quality of the deoxidizer. The lower end of the sealed recovery container 7 is provided with a recovery port, which is provided with an on / off valve (not shown). When the container is full of residual material, the on / off valve can be opened to transfer the residual material back to the mixing tank in a sealed manner for reuse.

[0025] See also Figure 1The deoxidizer packaging equipment 100 further includes a packaging machine 8. The feed hole 51 is connected to the feed inlet of the packaging machine 8. The packaging machine 8 bags the frozen deoxidizer. By connecting the feed hole 51 to the feed inlet of the packaging machine 8, the frozen deoxidizer can be directly packaged and sealed, thereby greatly reducing contact with air and preventing a decrease in the deoxidizer's deoxidation capacity.

[0026] See also Figure 1 The metering and pressing device 6 includes a metering and pressing piece 61, a pressing rod 62 and a driving device 63. The metering and pressing piece 61 is arranged at one end of the pressing rod 62, and the driving device 63 is connected to the other end of the pressing rod 62 to drive the metering and pressing piece 61 into the forming tube 5 to press a certain amount of frozen deoxidizer out of the discharge hole 51. The driving device 63 can be a cylinder. The input end and the output end of the driving device 63 are respectively connected to the air supply device. The driving device 63 also has a valve body for controlling the ventilation or air cutoff of the high-pressure cylinder. The valve body is electrically connected to the control system through a control line. By controlling the switch of the valve body, the extension and contraction of the output end of the cylinder can be controlled, and then the pressing rod 62 and the metering and pressing piece 61 can be driven to move and press the material. By using the driving device 63 and the pressing rod 62 to drive the metering and pressing piece 61, the frozen deoxidizer can be quantitatively discharged, which facilitates subsequent packaging operations and improves the automation capability of the equipment. The metering pressing member 61 includes circumferentially distributed cutting blades 611, and the cutting blades 611 enclose a quantitative space 612 with a certain capacity. When the metering pressing member 61 cuts, the frozen material fills the quantitative space, and the cutting blades are used to cut the long strips of frozen material. When the metering pressing member 61 reaches the discharge hole 51, the long strips of frozen material are separated from the metering pressing member 61 under the action of gravity and discharged from the discharge hole 51. In another embodiment, the metering pressing device 6 includes a metering pressing member 61, a pressing rod 62, a driving device 63 and a return spring. The driving device 63 includes a high-pressure gas supply device and a cylinder body. A piston is provided in the cylinder body, and the piston is connected to the pressing rod 62. The high-pressure gas supply device only provides a high air pressure in the cylinder body to make the pressing rod 62 extend out to press the material, and the return spring provides an elastic force to retract and reset the pressing rod 62, thereby achieving continuous pressing.

[0027] See also Figure 1The deoxidizer packaging equipment 100 also includes a mixing tank 9. An input port is provided at the upper end of the sealed blanking container 1. Sealing switches 11 and 12 are provided at both the output and input ends of the sealed blanking container 1. The mixing tank 9 is located above the sealed blanking container 1. The output end of the mixing tank 9 is connected to the input end of the sealed blanking container 1, and the recovery end of the mixing tank 9 is connected to the output end of the sealed recovery container 7. When the mixing tank 9 is feeding material into the sealed blanking container 1, the sealing switch 11 at the input end of the sealed blanking container 1 is opened, allowing the deoxidizer material to fall into the sealed blanking container 1. After the mixing tank 9 completes feeding the material into the sealed blanking container 1, the sealing switch 11 at the input end of the sealed blanking container 1 is closed to reduce the entry of air into the sealed blanking container 1. When the output end of the sealed blanking container 1 is feeding material into the feeding pipe 2, the sealing switch 12 at the output end of the sealed blanking container 1 is opened. By arranging the mixing tank 9 at the input end of the sealed blanking container 1, the deoxidizer can automatically fall directly into the sealed blanking container 1 after mixing is completed for preparation before packaging. In addition, the residual material generated after packaging can be recycled, realizing automated continuous operation, effectively improving production efficiency, and no waste is generated, which is conducive to reducing production costs.

[0028] In summary, the working principle of the deoxidizer packaging device 100 of the present invention is described in detail below: First, the various materials for making the deoxidizer are added to a mixing tank 9 in specific proportions. The formula for these materials is 52% reduced iron powder, 2% activated carbon, 30% water, 2% water-absorbing resin, 10% silicon dioxide, 1% sodium bromide, and 3% calcium oxide. Alternatively, the formula for these materials is 52% reduced iron powder, 2% activated carbon, 25% water, 2% water-absorbing resin, 15% silicon dioxide, 1% sodium bromide, and 3% calcium oxide. After mixing in the mixing tank 9, the deoxidizer is obtained in a powdered state. The deoxidizer is then transported to a sealed discharge container 1. It is then discharged from the output end of the sealed discharge container 1 and enters the feed pipe 2. At this point, the motor 31 is activated, driving the screw 32 to rotate. The screw 32 drives the deoxidizer in the feed pipe 2 forward, and during this movement, the deoxidizer is squeezed by the screw 32, compressing it into a long strip. At the same time, the refrigeration unit 4 freezes the deoxidizer in the feed pipe 2 through the freezing jacket 41, causing the deoxidizer to form a solid long strip in the feed pipe 2 and enter the forming tube 5 under the push of the screw 32. Then, the driving device 63 drives the pressing rod 62 to extend toward the discharge hole 51. The pressing rod 62 drives the metering pressing member 61 to extend into the forming tube 5, cut the deoxidizer in a fixed amount, and discharge it from the discharge hole 51 after cutting. The cut block of deoxidizer enters the feeding port of the packaging machine 8 through the discharge hole 51, and the packaging machine 8 then bags the deoxidizer. After the sealed bag is warmed up, the deoxidizer returns to a dispersed state, thereby increasing the deoxidation speed during use.

[0029] See also Figure 2 The deoxidizer packaging method of the present invention comprises the following steps: Step S1, adding the raw materials into the mixing tank 9 in proportion to mix them, obtaining a deoxidizer in powder form, and conveying it into the sealed discharge container 1; Step S2, delivering the powdered deoxidizer in the sealed discharge container 1 to the delivery pipe 2; Step S3, using the screw 32 to compress and transport the powdered deoxidizer in the feeding pipe 2; Step S4, using the refrigeration device 4 to freeze the deoxidizer in the feeding pipe 2 to form a long frozen material strip; Step S5, using the metering and pressing device 6 to cut the frozen material strips into blocks and output them; Step S6, using a packaging machine 8 to package the block deoxidizer; Step S7, recovering the remaining material after the frozen material is cut into long strips, and returning it to the temperature for reuse.

[0030] Compared with the prior art, the present invention is connected to the sealed unloading container 1 through the feeding pipe 2, so that the powdered deoxidizer can automatically fall into the feeding pipe 2, and then the deoxidizer in the feeding pipe 2 is compressed and transported forward by the compression device 3. At the same time, the compressed deoxidizer is frozen by the refrigeration device 4, so that the deoxidizer forms a frozen material strip, and finally the metering pressing device 6 on the forming tube 5 is quantitatively cut and unloaded; the whole process is carried out in a sealed container and tube, which greatly reduces the contact between the deoxidizer and the air, and by freezing the deoxidizer from a dispersed state to a solid state, the dispersed deoxidizer material is prevented from coming into contact with the air and causing oxidation loss. In addition, since the deoxidizer is still in a frozen solid state during unloading, no dust is generated, and no deoxidizer powder falls on the sealed edge of the packaging bag, thus effectively preventing the quality accident of the sandwiched material leaking. Moreover, after packaging, the frozen deoxidizer can be warmed up and restored to a powdered state, avoiding the deoxidation capacity decreasing due to the solid state, the deoxidation capacity is high, and the production cost is low.

[0031] The structure of the packaging machine 8 involved in the deoxidizer packaging equipment 100 of the present invention is well known to those skilled in the art and will not be described in detail here.

[0032] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made within the scope of the present invention are still within the scope of the present invention.
