Description

Technical Field

[0001] The utility model belongs to the field of aseptic filling, and in particular relates to aseptic filling equipment for food with a plug. Background Art

[0002] The aseptic filling process for stick foods (such as cheese sticks) is different from that for other foods because the packaging container for stick foods does not come from a single independent container, but is formed by folding the sheet in half and then blow-molding. In the filling equipment, the sheet will be distributed continuously and the various components will be densely arranged in a compact arrangement.

[0003] At present, before filling, the existing stick-type foods need to spray bactericidal agents on both sides of the unfolded and blown sheet materials for sterilization, and then after drying, the sheets are folded in half and blown into shape to form a molded sheet, and finally the stick insertion, filling and sealing operations are performed. The sheets need to be in the sterile environment of the sterile warehouse throughout the whole process, so a larger sterile warehouse is required. However, a large amount of sterile air needs to be continuously introduced into the larger sterile warehouse to construct and maintain the sterile environment, which makes the sterile environment maintenance cost of the sterile warehouse high. In addition, the sterilization area of ​​the unfolded and blown sheet materials is the sum of the areas of the front and back sides of the sheet materials. The large sterilization area requires a large amount of bactericides, which leads to high sterilization costs. The high sterilization environment maintenance costs and sterilization costs lead to excessively high overall production costs of stick-type foods. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an aseptic filling device for food with a plug, so as to solve the problem of large consumption of bactericide.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A sterile filling device for food with a plug-in rod comprises a sterile bin, a conveying component, a plug-in rod component, a filling component and a sealing component, wherein the conveying component has a conveying path, and the sterile filling device for food with a plug-in rod further comprises a sterilization component and a drying component, wherein the sterilization component, the drying component, the plug-in rod component, the filling component and the sealing component are sequentially distributed on the conveying path, the sterile bin comprises a sterilization chamber, a drying chamber, a plug-in rod chamber, a filling chamber and a sealing chamber, wherein the sterilization chamber, the drying chamber, the plug-in rod chamber, the filling chamber and the sealing chamber are connected, the sterilization operation end of the sterilization component extends into the sterilization chamber, the drying operation end of the drying component extends into the drying chamber, and the plug-in rod operation end of the plug-in rod component extends into the The filling operation end of the filling component extends into the filling chamber, the sealing operation end of the sealing component extends into the sealing chamber, the entire conveying path passes through the sterilization chamber and the drying chamber, the top of the conveying path passes through the rod insertion chamber, the filling chamber and the sealing chamber, the sterilization operation end moves in the vertical direction, and the movement range of the sterilization operation end intersects with the conveying path, the sterilization component extends into the conveying path through the sterilization operation end to spray sterilant into the conveying path, the drying operation end moves in the vertical direction, and the movement range of the drying operation end intersects with the conveying path, the drying component extends into the conveying path through the drying operation end to spray drying gas into the conveying path.

[0007] The technical solution has the following technical effects:

[0008] After the sheet is folded in half and blown into shape, the utility model drags the molded sheet into the sterilization cavity through the conveying component, and sprays a sterilizing agent on the outer surface of the molded sheet and the inner surface of the cavity through the sterilization operation end to sterilize the molded sheet, because the folded connecting part of the inner surface of the molded sheet after folding in half and blow-molding does not need to be sprayed with a sterilizing agent, that is, the surface of the molded sheet that needs to be sterilized is limited to the formed inner surface of the cavity and the outer surface of the molded sheet, while if the sheet is sterilized before folding in half and blow-molding, it is necessary to spray a sterilizing agent on both sides of the flat sheet, and the sterilization area is larger. Therefore, compared with the sheet that is not folded in half and blow-molded, the molded sheet requires a smaller sterilization area, so that the amount of sterilization required for the molded sheet is less, and spraying the sterilizing agent after the sheet is folded in half and blow-molded can reduce the consumption of the sterilizing agent, thereby reducing the amount of high-temperature sterile air used for drying, and reducing the sterilization and drying costs. By only extending the top of the sterilized molding sheet in turn and passing through the rod insertion cavity, filling cavity and sealing cavity, the cavity of the molding sheet is connected with the rod insertion cavity, filling cavity and sealing cavity through the opening located at the top of the molding sheet, ensuring that the inner surface of the molding sheet cavity is always in a sterile environment, and the molding sheet can be sequentially inserted, filled and sealed through the rod insertion component, filling component and sealing component, without the need for the entire molding sheet to pass through the rod insertion cavity, filling cavity and sealing cavity, the height of the rod insertion cavity, filling cavity and sealing cavity can be reduced, that is, the volume of the rod insertion cavity, filling cavity and sealing cavity can be reduced, thereby reducing the amount of sterile air required to construct the overall sterile environment of the sterile warehouse, reducing the construction conditions of the sterile environment of the sterile warehouse, thereby reducing the maintenance cost of the sterile environment, and greatly reducing the production cost.

[0009] In the above-mentioned aseptic filling equipment for food with inserted rods, the aseptic filling equipment for food with inserted rods also includes a clean warehouse arranged at the bottom of the aseptic warehouse, a clean cavity is arranged in the clean warehouse, the clean cavity is connected with the bottom of each cavity of the aseptic warehouse, and the bottom surface height of the rod insertion cavity, the filling cavity and the sealing cavity is higher than the bottom surface height of the sterilization cavity and the drying cavity, so that when the top of the conveying path passes through the rod insertion cavity, the filling cavity and the sealing cavity, the lower part of the conveying path extending out of the rod insertion cavity, the filling cavity and the sealing cavity is located in the clean cavity. The construction of the sterile environment in the sterilization cavity, the drying cavity, the rod insertion cavity, the filling cavity and the sealing cavity is achieved on the one hand by continuously introducing sterile air into these cavities, and on the other hand by continuously flowing out the sterile air in these cavities from the inlet of the sterilization cavity and the outlet of the sealing cavity. Because the flow rate of the inlet of the sterilization cavity and the outlet of the sealing cavity is limited, the construction of the sterile environment is limited by the size of the inlet of the sterilization cavity and the outlet of the sealing cavity. By connecting the clean chamber with the sterilization chamber, drying chamber, rod insertion chamber, filling chamber and sealing chamber above respectively, the clean chamber can provide a supplementary outlet for the discharge of sterile air in the sterilization chamber, drying chamber, rod insertion chamber, filling chamber and sealing chamber, so as to maintain the sterile environment of the sterilization chamber, drying chamber, rod insertion chamber, filling chamber and sealing chamber.

[0010] In the above-mentioned aseptic filling equipment for stick-type foods, a first air barrier compartment and a second air barrier compartment are respectively provided on both sides of the aseptic compartment, the first air barrier compartment is connected to the inlet of the sterilization chamber, and the second air barrier compartment is connected to the outlet of the sealing chamber. The first air barrier compartment is located at the inlet of the sterilization chamber, and the first air barrier compartment is connected to the sterilization chamber through the inlet of the sterilization chamber to separate the sterilization chamber from the outside world, and prevent bacteria in the outside air from entering the sterilization chamber through the inlet of the sterilization chamber to destroy the sterile environment of the sterilization chamber. The second air barrier compartment is located at the outlet of the sealing chamber, and the second air barrier compartment is connected to the sealing chamber through the outlet of the sealing chamber to separate the sealing chamber from the outside world, and prevent bacteria in the outside air from entering the sealing chamber through the outlet of the sealing chamber to destroy the sterile environment of the sealing chamber.

[0011] In the above-mentioned aseptic filling equipment for stick-type food, the conveying path is bent in the sterilization chamber and the drying chamber so that the part of the conveying path located in the sterilization chamber and the drying chamber is n-shaped. This can not only ensure that the formed sheet stays in the sterilization chamber and the drying chamber for a sufficient time to be thoroughly sterilized, but also shorten the length of the whole machine, making the whole machine structure more compact.

[0012] In the above-mentioned aseptic filling equipment for stick-type food, the sterilization component includes a first lifting component and a sterilization component. The sterilization component is installed on the first lifting component. The first lifting component drives the sterilization component to rise away from the conveying component or drives the sterilization component to descend to spray a sterilizer onto the formed sheet on the conveying component. The structure is simple and the operation is stable.

[0013] In the above-mentioned aseptic filling equipment for food of the type of inserted rod, the sterilization component includes a main body and a plurality of spray units, the spray units are connected to the main body and distributed along the conveying path, the spray units include an inner tube and an outer tube extending vertically, two outer tubes are provided, the two outer tubes are provided on both sides of the inner tube, the bottom of the inner tube is provided with an inner nozzle, and the side wall of the outer tube facing the inner tube is provided with an outer nozzle. When the first lifting component drives the sterilization component to descend into place, the inner tube extends into the cavity through the opening at the top of the forming sheet, the sterilizer sprays downward from the inner nozzle and flows upward, so as to achieve the coverage and sterilization of the inner surface of the cavity of the forming sheet by the sterilizer, the outer tube is located on both sides of the forming sheet, the outer nozzles on the two outer tubes are respectively arranged toward the two outer side surfaces of the forming sheet, the sterilizer is sprayed from the outer nozzle toward the outer side surface of the forming sheet on the side, so as to achieve the coverage and sterilization of the outer surface of the forming sheet by the sterilizer, so that the spray unit can sterilize the forming sheet comprehensively and thoroughly.

[0014] In the above-mentioned aseptic filling equipment for food of the type of inserted rods, the drying component includes a second lifting component and a drying component having the same structure as the sterilization component. The drying component is installed on the second lifting component. The second lifting component drives the drying component to rise to move away from the conveying component or drives the drying component to descend to spray drying gas onto the formed sheet on the conveying component. When the second lifting component drives the drying component to descend into place, the drying component can spray drying gas onto the formed sheet to dry the sterilizer on the outer surface of the formed sheet and the inner surface of the cavity. The structure of the drying component in this embodiment is the same as that of the sterilization component, the only difference being that drying gas is introduced into the drying component, while sterilizer is introduced into the sterilization component. The drying component has the same structure as the sterilization component, so that the drying effect of the drying component on the formed sheet is better, thereby improving the drying efficiency.

[0015] The features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example:

[0038] A kind of aseptic filling equipment for food with sticks, such as Figures 1 to 6As shown, it includes a sterile warehouse 100, a conveying component 600, a sterilization component 400, a drying component 500, a rod inserting component 710, a filling component 720 and a sealing component 730. The conveying component 600 is used to drag the formed sheet 800 formed by folding and blowing, so that the formed sheet 800 moves in steps. The conveying component 600 has a conveying path 610. The path that the formed sheet 800 passes as a whole when being dragged by the conveying component 600 is the conveying path 610 of the conveying component 600. The sterilization component 400, the drying component 500, the rod inserting component 710, the filling component 720 and the sealing component 730 are distributed on the conveying path 610 in sequence along the conveying direction of the formed sheet 800. The aseptic warehouse 100 has a sterilization chamber 110, a drying chamber 120, a rod insertion chamber 130, a filling chamber 140 and a sealing chamber 150 which are adjacently arranged. The sterilization chamber 110, the drying chamber 120, the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150 are interconnected, and sterile air is passed through the interior of the sterilization chamber 110 and the drying chamber 120 to form a sterile environment. The conveying path 610 passes through the sterilization chamber 110 and the drying chamber 120, that is, when the formed sheet 800 passes through the sterilization chamber 110 and the drying chamber 120, the formed sheet 800 is conveyed from top to bottom. The entire part is located in the sterilization chamber 110 and the drying chamber 120, and the top of the conveying path 610 passes through the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150. That is, when the formed sheet 800 passes through the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150, only the top of the forming sheet 800 with the cavity 810 opening 820 is located in the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150, and the rest of the formed sheet 800 is located outside the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150.

[0039] The sterilization component 400 has a sterilization operation end for spraying sterilant, the sterilization operation end extends into the sterilization chamber 110 and moves in the vertical direction, the movement range of the sterilization operation end intersects with the conveying path 610, and the sterilization component 400 extends into the conveying path 610 through the sterilization operation end to spray sterilant into the conveying path 610, so that the outer surface of the formed sheet 800 and the inner surface of the cavity 810 are evenly covered with sterilant for sterilization. The drying component 500 has a drying operation end for spraying drying gas, the drying operation end extends into the drying chamber 120 and moves in the vertical direction, the movement range of the drying operation end intersects with the conveying path 610, and the drying component 500 extends into the conveying path 610 through the drying operation end to spray drying gas into the conveying path 610 to dry the outer surface of the formed sheet 800 and the inner surface of the cavity 810. The rod inserting component 710 has a rod inserting operation end 711, which extends into the rod inserting cavity 130 to insert the material rod into the cavity 810 of the forming sheet 800. The filling component 720 has a filling operation end 721, which extends into the filling cavity 140 to fill the material into the cavity 810 of the forming sheet 800. The sealing component 730 has a sealing operation end 731, which extends into the sealing cavity 150 to seal the opening 820 of the cavity 810 of the forming sheet 800 located in the sealing cavity 150.

[0040] After the sheet is folded and blown into shape, the utility model drags the formed sheet 800 into the sterilization chamber 110 through the conveying component 600, and sprays the sterilizing agent on the outer surface of the formed sheet 800 and the inner surface of the cavity 810 through the sterilization operation end to sterilize the formed sheet 800, because the folded connecting part of the inner surface of the formed sheet 800 after folding and blown into shape does not need to be sprayed with the sterilizing agent, that is, the surface of the formed sheet 800 that needs to be sterilized is limited to the inner surface of the formed cavity 810 and the formed sheet. The outer surface of the sheet 800 is folded in half and blown into shape, and if the sheet is sterilized before it is folded in half and blown into shape, it is necessary to spray the sterilizer on both sides of the flat sheet, and the sterilization area is larger. Therefore, compared with the sheet that is not folded in half and blown into shape, the molded sheet 800 requires a smaller sterilization area, so that the amount of sterilizer required for the molded sheet 800 is less. Spraying the sterilizer after the sheet is folded in half and blown into shape can reduce the consumption of the sterilizer, thereby reducing the amount of high-temperature sterile air used for drying, and reducing the cost of sterilization and drying. By only extending the top of the sterilized forming sheet 800 into and passing through the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150 in sequence, the cavity 810 of the forming sheet 800 is connected with the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150 through the opening 820 located at the top of the forming sheet 800, ensuring that the inner surface of the cavity 810 of the forming sheet 800 is always in a sterile environment, and the forming sheet 800 can be sterilized by the rod insertion component 710, the filling component 720 and the sealing component 730. The operations of rod insertion, filling and sealing are performed in sequence. There is no need for the entire formed sheet 800 to pass through the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150. The height of the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150 can be reduced, that is, the volume of the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150 can be reduced, thereby reducing the amount of sterile air required to construct the overall sterile environment of the sterile warehouse, reducing the construction conditions of the sterile environment of the sterile warehouse, thereby reducing the cost of maintaining the sterile environment, and greatly reducing the production cost.

[0041] In the present embodiment, the aseptic filling equipment for stick-type foods further includes a clean bin 200, which is disposed at the bottom of the aseptic bin 100. A clean chamber 210 is disposed in the clean bin 200, and dust-free air is passed through the clean chamber 210 to form a dust-free environment. The clean chamber 210 is located as a whole below the sterilization chamber 110, the drying chamber 120, the stick-insertion chamber 130, the filling chamber 140 and the sealing chamber 150. The top of the clean chamber 210 is respectively connected to the bottom of the sterilization chamber 110, the drying chamber 120, the stick-insertion chamber 130, the filling chamber 140 and the sealing chamber 150. The bottom of the aseptic bin 100 is not flat. The bottom heights of the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150 are all higher than the bottom heights of the sterilization cavity 110 and the drying cavity 120, so that when the molding sheet 800 that is entirely located in the sterilization cavity 110 and the drying cavity 120 enters the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150, only the top of the molding sheet 800 is in the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150, and the other parts except the top (that is, the lower part of the molding sheet 800 that extends out of the rod insertion cavity 130, the filling cavity 140 and the sealing cavity 150) are all in the same clean cavity 210. The construction of a sterile environment in the sterilization chamber 110, the drying chamber 120, the rod insertion chamber 130, the filling chamber 140 and the sealing chamber 150 is achieved on the one hand by continuously introducing sterile air into these chambers, and on the other hand by continuously allowing the sterile air in these chambers to flow out from the inlet of the sterilization chamber 110 and the outlet of the sealing chamber 150. Because the flow rates of the inlet of the sterilization chamber 110 and the outlet of the sealing chamber 150 are limited, the construction of a sterile environment is limited by the size of the inlet of the sterilization chamber 110 and the outlet of the sealing chamber 150. By connecting the clean chamber 210 with the sterilization chamber 110, drying chamber 120, rod insertion chamber 130, filling chamber 140 and sealing chamber 150 above respectively, the clean chamber 210 can provide a supplementary outlet for the discharge of sterile air in the sterilization chamber 110, drying chamber 120, rod insertion chamber 130, filling chamber 140 and sealing chamber 150, so as to maintain the sterile environment of the sterilization chamber 110, drying chamber 120, rod insertion chamber 130, filling chamber 140 and sealing chamber 150.

[0042] like Figure 3As shown, the first air barrier chamber 310 and the second air barrier chamber 320 are respectively provided on both sides of the sterile chamber 100 in this embodiment, and the first air barrier chamber 310 and the second air barrier chamber 320 are sterile environments. The first air barrier chamber 310 is located at the entrance of the sterilization chamber 110, and the first air barrier chamber 310 is connected with the sterilization chamber 110 through the entrance of the sterilization chamber 110 to separate the sterilization chamber 110 from the outside world, so as to prevent bacteria in the outside air from entering the sterilization chamber 110 through the entrance of the sterilization chamber 110 and destroying the sterile environment of the sterilization chamber 110; the second air barrier chamber 320 is located at the exit of the sealing chamber 150, and the second air barrier chamber 320 is connected with the sealing chamber 150 through the exit of the sealing chamber 150 to separate the sealing chamber 150 from the outside world, so as to prevent bacteria in the outside air from entering the sealing chamber 150 through the exit of the sealing chamber 150 and destroying the sterile environment of the sealing chamber 150. In this embodiment, there are various ways to construct the sterile environment in the first air barrier chamber 310 and the second air barrier chamber 320. It can be constructed by introducing external sterile air into the first air barrier chamber 310 and the second air barrier chamber 320, or by extracting the air in the first air barrier chamber 310 and the second air barrier chamber 320.

[0043] In this embodiment, the conveying path 610 of the formed sheet 800 in the sterilization chamber 110 and the drying chamber 120 is not a straight line extending left and right, but a bent arrangement, such as Figure 4 As shown, the formed sheet 800 will bypass the roller 160 in the sterilization chamber 110 and the drying chamber 120 to form a conveying path 610 extending forward and backward, respectively, so that the portion of the conveying path 610 located in the sterilization chamber 110 and the drying chamber 120 is in an n-shape when viewed from above. This can ensure that the formed sheet 800 stays in the sterilization chamber 110 and the drying chamber 120 for a sufficient time to be thoroughly sterilized, and can also shorten the length of the entire machine (i.e., the length in the left-right direction in the figure), making the entire machine structure more compact.

[0044] In this embodiment, if Figure 3 As shown, the sterilization component 400 includes a first lifting component 410 and a sterilization component 420. The sterilization component 420 is installed on the first lifting component 410. The first lifting component 410 can drive the sterilization component 420 to rise or fall. When the first lifting component 410 drives the sterilization component 420 to rise, the sterilization component 420 is away from the forming sheet 800. When the first lifting component 410 drives the sterilization component 420 to fall into place, the sterilization component 420 can spray a sterilant to the forming sheet 800 to sterilize the forming sheet 800. The structure is simple and the operation is stable. Figure 5As shown, the sterilization component 420 includes a main body 421 and a plurality of spray units 422. The top of the spray unit 422 is connected to the main body 421, and the plurality of spray units 422 are evenly spaced along the conveying path 610, so that when the first lifting component 410 drives the sterilization component 420 to descend, the plurality of spray units 422 spray sterilizers inside and outside a plurality of adjacent cavities 810 on the forming sheet 800, respectively, to improve the sterilization efficiency. Each spray unit 422 includes an inner tube 4221 and two outer tubes 4223, the tops of the inner tube 4221 and the outer tubes 4223 are connected to the main body 421, the lower parts of the inner tube 4221 and the outer tube 4223 extend vertically, and the two outer tubes 4223 are respectively arranged on the opposite sides of the inner tube 4221, the inner nozzle 4222 of the inner tube 4221 for spraying bactericidal agent is arranged at the bottom of the inner tube 4221, the outer nozzle 4224 of the outer tube 4223 for spraying bactericidal agent is arranged on the side wall of the outer tube 4223, and the outer nozzle 4224 is arranged on the side wall of the outer tube 4223 facing the inner tube 4221, each outer tube 4223 may have one or more outer nozzles 4224, preferably, each outer tube 4223 is provided with multiple outer nozzles 4224.

[0045] When the first lifting component 410 drives the sterilization component 420 to descend into place, the inner tube 4221 extends into the cavity 810 through the opening 820 at the top of the molding sheet 800, and the sterilizer is sprayed downward from the inner nozzle 4222 and flows upward to achieve coverage and sterilization of the inner surface of the cavity 810 of the molding sheet 800 by the sterilizer. The outer tube 4223 is located on both sides of the molding sheet 800, and the outer nozzles 4224 on the two outer tubes 4223 are respectively arranged toward the two outer side surfaces of the molding sheet 800. The sterilizer is sprayed from the outer nozzle 4224 toward the outer side surface of the molding sheet 800 on the side to achieve coverage and sterilization of the outer surface of the molding sheet 800 by the sterilizer, so that the injection unit 422 can sterilize the molding sheet 800 comprehensively and thoroughly.

[0046] The drying component 500 includes a second lifting component 510 and a drying component 520. The drying component 520 is installed on the second lifting component 510. The second lifting component 510 can drive the drying component 520 to rise or fall. When the second lifting component 510 drives the drying component 520 to rise, the drying component 520 is away from the forming sheet 800. When the second lifting component 510 drives the drying component 520 to fall into place, the drying component 520 can spray drying gas (such as high-temperature sterile hot air) to the forming sheet 800 to dry the bactericide on the outer surface of the forming sheet 800 and the inner surface of the cavity 810. The structure of the drying component 520 in this embodiment is the same as that of the sterilization component 420. The only difference is that the drying component 520 is fed with drying gas, while the sterilization component 420 is fed with bactericide. The drying component 520 has the same structure as the sterilization component 420, so that the drying component 520 has a better drying effect on the forming sheet 800 and improves the drying efficiency.
