Description

Technical Field

[0001] This utility model relates to the field of coffee beverage preservation technology, specifically a nitrogen-filled preservation device for coffee beverages. Background Technology

[0002] Coffee beverages are prone to oxidation and acidification at room temperature, resulting in unpleasant flavors and sediment, which affects quality. To improve the flavor stability of coffee liquid, nitrogen can be introduced to replace the air inside the packaging, thereby isolating oxygen and effectively delaying the oxidation of various substances in the coffee liquid.

[0003] Existing nitrogen-filling preservation technology typically uses a single nozzle for nitrogen filling. The nozzle is placed on top of the protective layer of the coffee storage capsule, and nitrogen is filled directly. The capsule is then sealed after filling. During the nitrogen filling process, the single nozzle generates a large impact force, which can easily lead to uneven nitrogen distribution, large liquid surface disturbance, and high residual oxygen rate. This results in insufficient nitrogen filling inside the coffee preservation capsule, affecting the subsequent coffee preservation time and reducing the efficiency of the nitrogen-filling preservation equipment. Optimization and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a nitrogen-filling preservation device for coffee beverages, in order to solve the problem mentioned in the background art that when filling with nitrogen using a single nozzle, uneven nitrogen distribution is likely to occur, resulting in a high residual oxygen rate inside the coffee storage container and affecting the coffee preservation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nitrogen-filling preservation device for coffee beverages, comprising: a processing table, a positioning plate provided at the bottom inner side of the processing table, and a front guard plate connected to the inner front side of the processing table; a nitrogen-filling control pump installed on one side of the front end of the processing table; and further comprising a filling adjustment assembly and a support adjustment assembly.

[0006] The filling adjustment assembly includes an adjustment plate connected to the inner center of the processing table. An installation tube is located at the bottom of the adjustment plate, and a nozzle is located inside the installation tube. A pressing sleeve is located at the top of the inner side of the installation tube. The filling adjustment assembly is used for nitrogen filling position adjustment. The support adjustment assembly includes a rubber sleeve located inside a positioning plate. A grooved push plate is located at the bottom of the positioning plate. The support adjustment assembly is used for supporting and adjusting the filling product.

[0007] Preferably, the bottom wall of the mounting tube is provided with an adjustment groove, and a rotating rod is provided on the inner side of the adjustment groove.

[0008] Preferably, a guide rod is connected to the middle of the inner bottom end of the mounting tube, and the pressing sleeve is disposed on the outside of the guide rod.

[0009] Preferably, a rotating connecting rod is connected to the outside of the pressing sleeve, and the nozzle is connected to the bottom end of the rotating connecting rod.

[0010] Preferably, the inner top of the processing table is connected to a top fixing plate, and the bottom of the top fixing plate is connected to a lifting extrusion plate.

[0011] Preferably, the outer walls of the positioning plate are provided with snap-fit ​​grooves on both sides.

[0012] Preferably, each of the four inner corners of the positioning plate is connected with an elastic connecting rod.

[0013] Preferably, a telescopic cylinder is installed at the bottom inner side of the processing table, and the grooved push plate is disposed at the top of the telescopic cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves setting an installation tube at the connection between the coffee capsule and the nozzle, and then setting six nozzles inside the installation tube. The angle of the nozzles can be adjusted within a certain range as the sleeve is raised and lowered, filling the coffee capsule with high-purity nitrogen gas. This allows the nitrogen gas to evenly cover the surface of the coffee beverage to form a protective layer. The multi-directional nitrogen filling can improve the uniformity of the protective layer and make the subsequent protection and preservation effect last longer.

[0016] When the coffee capsule is placed in the positioning hole inside the positioning plate, the stability is improved by squeezing with a rubber sleeve. After filling and sealing, the grooved pusher plate at the bottom pushes the filled coffee capsule upwards towards the positioning plate, making it easy for operators to pick up and collect, thus improving processing efficiency.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a nitrogen-filled preservation device for coffee beverages, including: a processing table 1, a positioning plate 2 is provided at the bottom inner side of the processing table 1, and a front guard plate 3 is connected to the inner front side of the processing table 1, and a nitrogen-filled control pump 4 is installed on one side of the front side of the processing table 1.

[0025] The filling adjustment assembly includes an adjustment plate 5, which is connected to the inner middle of the processing table 1. The bottom end of the adjustment plate 5 is provided with an installation tube 6, and the inner side of the installation tube 6 is provided with a nozzle 12. The top end of the inner side of the installation tube 6 is provided with a pressing sleeve 10. The filling adjustment assembly is used for nitrogen filling position adjustment.

[0026] Specifically, such as Figure 3 As shown, an adjustment groove 7 is provided inside the bottom wall of the installation pipe 6, and a rotating rod 8 is provided on the inner side of the adjustment groove 7. The adjustment groove 7 is elliptical, and the rotating rod 8 in the middle is used for the rotation adjustment of the nozzle 12.

[0027] Specifically, such as Figure 3 As shown, a guide rod 9 is connected to the middle of the bottom inner side of the mounting tube 6, and a pressing sleeve 10 is set on the outside of the guide rod 9. The pressing sleeve 10 can move up and down on the outside of the guide rod 9.

[0028] Specifically, such as Figure 3As shown, a rotating connecting rod 11 is connected to the outside of the pressing sleeve 10, and the nozzle 12 is connected to the bottom end of the rotating connecting rod 11. The nozzle 12 and the rotating connecting rod 11 are rotatably connected, and the rotating connecting rod 11 and the pressing sleeve 10 are also rotatably connected.

[0029] Specifically, such as Figure 2 As shown, the top of the inner side of the processing table 1 is connected to a top fixing plate 13, and the bottom of the top fixing plate 13 is connected to a lifting pressing plate 14. The lifting and lowering of the lifting pressing plate 14 is used to synchronously adjust all the pressing sleeves 10. The lifting pressing plate 14 is fixedly connected to the top of the pressing sleeve 10.

[0030] The support adjustment assembly includes a rubber sleeve 16, which is disposed inside the positioning plate 2. The bottom end of the positioning plate 2 is provided with a grooved push plate 18. The support adjustment assembly is used for supporting and adjusting the filling product.

[0031] Specifically, such as Figure 4 As shown, both sides of the outer wall of the positioning plate 2 are provided with snap-fit ​​grooves 15. The snap-fit ​​grooves 15 are used for direct insertion and fixing of the positioning plate 2 to the inner wall of the processing table 1, which facilitates the replacement of positioning plates 2 with different hole diameters.

[0032] Specifically, such as Figure 4 As shown, each of the four inner corners of the positioning plate 2 is connected to an elastic connecting rod 17. The elastic connecting rod 17 is fixedly connected to the top four corners of the grooved push plate 18 and passes through the positioning plate 2 to prevent the grooved push plate 18 from shifting its position when it is raised or lowered.

[0033] Specifically, such as Figure 4 As shown, a telescopic cylinder 19 is installed on the inner bottom of the processing table 1, and a grooved push plate 18 is set on the top of the telescopic cylinder 19. The telescopic cylinder 19 controls the upgrading of the grooved push plate 18 to eject the coffee nitrogen-filled capsule.

[0034] In this embodiment: an installation tube 6 is provided at the connection between the coffee filling capsule and the nozzle 12, and six nozzles 12 are provided inside the installation tube 6. The angle of the nozzles 12 is adjusted within a certain range as the pressing sleeve 10 is raised and lowered. High-purity nitrogen is filled into the coffee capsule so that the nitrogen can evenly cover the surface of the coffee beverage to form a protective layer. When the coffee capsule is placed in the positioning hole inside the positioning plate 2, the stability is improved by the compression of the rubber sleeve 16. After filling and sealing, the grooved push plate 18 at the bottom pushes the filled coffee capsule upwards and closes it to the positioning plate 2, making it easy for the operator to pick up and collect.

[0035] The specific steps of this solution are as follows: When performing nitrogen-filled preservation on coffee beverage capsules, first place the capsule in the corresponding positioning hole inside the positioning plate 2. The internal rubber sleeve 16 will improve the stability of the capsule placement. Then, close the front guard plate 3. At this time, the adjusting plate 5 is lowered as a whole, so that the cover plate at the bottom of the mounting tube 6 fits against the top of the capsule. Then, nitrogen is filled by connecting the nitrogen filling control pump 4 on the outside to the nozzle 12 on the inside. During the nitrogen filling process, the lifting and pressing plate 14 drives the pressing sleeve 10 to be raised and lowered on the outside of the guide rod 9, so that the rotating connecting rod 11 drives the nozzle 12 to rotate. Because the outside of the nozzle 12 is connected to the rotating rod 8... The installation pipe 6 is connected, so it controls the bottom of the nozzle 12 to swing and adjust. There are six nozzles 12 arranged in a ring, which can be operated synchronously. The nitrogen filling angle of the nozzle 12 is adjusted according to the inner diameter of the capsule, so that the nitrogen can evenly cover the surface of the coffee beverage to form a protective layer. The dispersed filling will not cause the coffee liquid to be stirred, reducing the probability of coffee liquid splashing. Multi-directional nitrogen filling can improve the uniformity of the protective layer and make the subsequent protection and preservation effect longer lasting. After the nitrogen filling is completed, it is directly sealed. Then the telescopic cylinder 19 drives the grooved push plate 18 to move upward, squeeze the bottom of the capsule, and push the capsule out from the inside of the positioning plate 2 for easy collection by the operator.
