Description

Nitrogen filling device for beverages Technical Field

[0001] The present invention relates to a beverage preparation device, in particular to a beverage preparation device with additives. Background Art

[0002] Nitrogen injection into beverages can enhance their flavor and richness. Within limits and within legal regulations, it has become a popular choice for many beverage companies, particularly in beer, coffee, and tea. For example, Taiwan Invention Patent No. M548974, "Equipment for Extracting Nitrogen-Containing Beverages," discloses a method of injecting nitrogen into a pressure vessel within a predetermined pressure range. The nitrogen pressure then forces the beverage out through a second pipe and an ejector, creating a nitrogen-containing beverage.

[0003] According to the prior art, the pressurized nitrogen source can be provided by a nitrogen tank, which is used to inject nitrogen into the storage space of the pressure barrel through a first pipeline. However, this single-path filling method cannot ensure that the liquid molecules of the beverage in the flow path are fully exposed to the nitrogen, resulting in limited nitrogen effects. As a result, the quality stability and taste of the nitrogen-containing beverage produced still need to be improved. Summary of the Invention

[0004] The technical problem addressed by this invention is that a pressurized nitrogen source can be provided through a nitrogen tank to provide a storage space for nitrogen injection into a pressure tank via a first pipeline. However, this single-path filling method does not ensure that the liquid molecules of the beverage in the flow path are fully exposed to the nitrogen, resulting in limited nitrogen effects. Consequently, the quality stability and taste of the resulting nitrogen-containing beverages still need to be improved.

[0005] The present invention solves the technical problem by adopting a technical solution: providing a nitrogen filling device for beverages, comprising a beverage storage cylinder connected to an inner liner unit via a beverage inlet pipe, and connected to a beverage outlet pipe via the inner liner unit; a nitrogen storage cylinder connected to one end of a three-way distribution unit, and the other two ends of the three-way distribution unit respectively connected to a first nitrogen pipe and a second nitrogen pipe, the first nitrogen pipe communicating with the beverage storage cylinder; the second nitrogen pipe branches into a nitrogen injection manifold communicating with the inner liner unit, and the second nitrogen pipe further branches into a nitrogen purge manifold to the inner liner unit, thereby forcing and promoting sufficient mixing of nitrogen in the inner liner unit with the beverage and forcing the beverage to the beverage outlet pipe.

[0006] The beneficial effect of the present invention is that nitrogen can be added to the flow path of the beverage in the storage cylinder, the beverage inlet pipe, the beverage outlet pipe and the inner liner unit in a timely and evenly distributed manner, thereby promoting more complete and even contact between the beverage and the nitrogen, and further improving the delicate and rich taste of the beverage.

[0032] Referring to FIG. 1 , in conjunction with FIG. 2 and FIG. 3 , the present invention relates to a nitrogen filling device for beverages, comprising a beverage storage cartridge 1 connected to an inner liner unit 3 via a beverage inlet pipe 11, which in turn is connected to a beverage outlet pipe 12. A nitrogen storage cartridge 2 is also provided, connected to one end of a three-way distribution unit 4. The other ends of the three-way distribution unit 4 are respectively connected to a first nitrogen pipe 41 and a second nitrogen pipe 42. The first nitrogen pipe 41 communicates with the beverage storage cartridge 1 to provide initial mixing of nitrogen with the beverage. The second nitrogen pipe 42 branches into a nitrogen injection manifold 421 that communicates with the inner liner unit 3 to provide further mixing of nitrogen with the beverage. The second nitrogen pipe 42 further branches into a nitrogen purge manifold 422 that passes through the inner liner unit 3 and is connected to the beverage outlet pipe 12 to force and promote thorough mixing of nitrogen with the beverage in the beverage outlet pipe 12. Furthermore, the negative pressure generated by the inner container unit 3 during the exhaust process can affect the blockage and interference of the beverage outlet pipe 12 when the beverage is discharged, thereby achieving a mixing effect and stable beverage output.

[0033] Thus, the present invention provides a flow path for the beverage in the storage cylinder, the beverage inlet pipe, the beverage outlet pipe, and the inner liner unit, so that nitrogen can be added in a timely and evenly distributed manner, thereby promoting more complete and even contact between the beverage and the nitrogen, and further enhancing the delicate and rich taste of the beverage.

[0034] In a preferred embodiment of the present invention, the first nitrogen pipe 41 is provided with a first control device 61. The first control device 61 is electrically connected to a nitrogen supply switch 61A. When the beverage in the beverage cylinder 1 is replaced or the beverage cylinder 1 is repaired, the nitrogen supply switch 61A can be temporarily closed.

[0035] In a preferred embodiment of the present invention, the second nitrogen pipe 42 is provided with a second controller 62 , and the second controller 62 is electrically connected to a nitrogen inlet valve 62A to adjust and provide the nitrogen supply required for different beverages.

[0036] In a preferred embodiment of the present invention, the nitrogen purge manifold is provided with a third controller 64, and the third controller 64 is electrically connected to a nitrogen purge valve (not shown) to regulate the nitrogen flow rate of the nitrogen purge manifold 422 through the inner liner unit 3 and connected to the beverage outlet pipe 12, thereby adjusting the purge intensity.

[0037] In a preferred embodiment of the present invention, an exhaust valve 63A is further provided. The exhaust valve 63A is provided on the inner tank unit 3 to adjust the exhaust opening and the on / off of the exhaust. The exhaust valve 63A is provided with an exhaust control device (not shown) to adjust the exhaust volume and open and close the exhaust.

[0038] In a preferred embodiment of the present invention, as shown in FIG4 , the beverage outlet pipe 12 is connected to a mixer 5 , and a spiral groove 51 is provided along the axial direction on the inner edge of the mixer 5 . The hysteresis effect of the spiral groove 51 is utilized to provide further mixing of nitrogen and beverage.

[0039] In a preferred embodiment of the present invention, the beverage inlet pipe 11 and the beverage inlet pipe 11 are each provided with a regulating valve 111, 112 to adjust the flow rate of different beverages and the process.

[0040] Various controllers and regulating valves can be used to avoid the need for on-site personnel to constantly adjust the pressure changes and flow supply of the beverage and nitrogen during the nitrogen beverage preparation process, which may even lead to unstable beverage delivery, such as often having nitrogen but no beverage, or having beverage but no effective nitrogen mixing.
