Description

Technology Field

[0001] The present invention relates to a filtration device of a new structure capable of effectively removing residue contained in the juice while preventing oxidation of the citrus juice. Background Technology

[0002] Generally, fruit juice is typically produced by pressing the fruit using a juicer.

[0003] However, when citrus fruits are juiced in this way, a large amount of residue, such as pulp, is included in the juice, and the bitter taste derived from this residue dissolves into the juice.

[0004] Therefore, recently, a method has been used to remove bitterness and improve taste by removing the pulp contained in the juice through a separate filtering process of citrus juice.

[0005] Meanwhile, the filtration device used to remove pulp contained in the citrus juice in this manner is configured such that an outlet is formed at the bottom of a storage container in which the juice is stored, and a filter is provided at the outlet, so that the pulp is filtered as the juice stored in the storage container passes through the filter by gravity.

[0006] However, in this method, as the juice is exposed to the air, not only does the juice oxidize and change in taste, but the filtered pulp also accumulates on the upper surface of the filter, preventing the juice from passing through the filter properly, and consequently, a problem arises in that it takes a long time to filter the juice.

[0007] Therefore, a new method to solve these problems became necessary. Prior art literature

FIG. 4 is a side cross-sectional view showing the disassembled state of the filtration unit of the filtration device according to the present invention. Specific details for implementing the invention

[0017] The present invention will be described in detail below with reference to the attached exemplary drawings.

[0018] FIGS. 1 to 4 illustrate a filtration device according to the present invention, comprising a filtration unit (A) having a filter body (40) inside, a keg (60) in which a juice is stored inside and which is connected to the filtration unit (A) through a supply pipe (61), and a gas tank (70) connected to the keg (60) through a supply pipe (71) to supply high-pressure CO2 gas to the keg (60).

[0019] As illustrated in FIGS. 2 to 4, the above filtration unit (A) is composed of a housing (10) having a tube shape extending in the front-rear direction and a discharge port (14) formed at the rear end, an extension tube (20) extending upwardly inclined from the upper surface of the housing (10), a filter tube (30) extending from the inside of the extension tube (20) to the discharge port (13), a filter body (40) coupled to the upper end of the filter tube (30), and a lid (50) coupled to the upper end of the extension tube (20).

[0020] The housing (10) is divided into an internal space into a front injection section (12) and a rear discharge section (13) by a plate (11) provided in the middle section.

[0021] The extension tube (20) is configured in a tubular shape such that its diameter corresponds to that of the housing (10), and is connected to the housing (10) so as to be connected to the injection part (12).

[0022] The above filter body (30) is configured with an inlet part (31) that is arranged concentrically with the extension body (20) inside the extension body (20) and has an inlet port (31a) formed at the top, and a connecting part (32) that is provided to extend rearward inside the housing (10) and has a connecting hole (32a) formed to connect to the plate (11).

[0023] At this time, a ring-shaped protrusion (31b) protruding inward is formed in the inlet (31a), so that the inner diameter of the inlet (31a) is smaller than the inner diameter of the inlet (31).

[0024] The filter body (40) is composed of a metal filter body (41) that extends in the vertical direction, has an open top surface, and has a plurality of through holes (41a, 41b) formed on its circumference, a filter member (42) fixed to the inner circumference of the filter body (41), and a fixing plate (43) that is coupled to the top of the filter body (41) and fixed inside the extension tube (20).

[0025] The filter body (41) is installed in the inlet section (31) such that its lower end is inserted into the interior of the inlet section (31) through the inlet port (31a) and its upper end protrudes above the inlet port (31a).

[0026] At this time, the outer diameter of the filter body (41) is configured to correspond to the inner diameter of the inlet (31a), so that when the filter body (41) is inserted into the inlet (31a), the filter body (41) comes into close contact with the inlet (31a) and blocks the inlet (31a).

[0027] The filter member (42) is formed in the form of a thin sheet, such as a non-woven fabric, and is attached and fixed to the inner surface of the filter body (41) to cover a portion of the through holes (41a, 41b) formed in the filter body (41).

[0028] At this time, the filter member (42) is provided only on the lower side of the middle part inside the filter body (41) so as to cover only the inner surface of the part inserted into the interior of the inlet part (31) from the inner surface of the filter body (41), so that the through holes (41a, 41b) of the filter body (41) are divided into an exhaust through hole (41a) blocked by the filter member (42) and an inlet through hole (41b) not blocked by the filter member (42).

[0029] The above fixing plate (43) is configured in the shape of a disc with an outer diameter slightly smaller than the outer diameter of the filter tube (30), and a protrusion (43a) is formed on the lower side to be coupled to the top of the filter body (41).

[0030] Accordingly, after attaching the filter body (41) to the fixed plate (43), if the filter body (41) is inserted into the interior of the inlet (31), the fixed plate (43) is caught on the upper part of the filter tube (30), and at this time, only the discharge through hole (41a) formed in the filter body (41) is inserted into the interior of the filter tube (30).

[0031] The lid (50) is screw-coupled to the top of the extension tube (20), thereby sealing the top of the extension tube (20) by fixing the fixing plate (43) so that it is watertightly coupled to the top of the extension tube (20).

[0032] As shown in FIG. 1, the keg (60) is configured in the shape of a high-strength metal material and stores juice produced by compressing fruit inside. On the upper surface, an outlet (62) to which the supply pipe (61) is connected and an air supply port (63) to which the supply pipe (71) is connected are formed.

[0033] At this time, a stopper (64) is attached to the discharge port (62).

[0034] And, the supply pipe (61) is extended at one end through the stopper (64) to the lower interior of the keg (60), and the other end is connected to the injection part (12) at the front of the housing (10).

[0035] The gas tank (70) is connected to the air supply port (63) of the keg (60) through the air supply pipe (71) and configured to supply high-pressure CO2 gas to the upper interior of the keg (60).

[0036] At this time, a valve (72) is provided in the middle part of the above-mentioned air supply pipe (71) to control the flow of CO2 gas supplied to the keg (60) through the air supply pipe (71).

[0037] Accordingly, when the valve (72) is opened, as shown in FIG. 1, high-pressure CO2 gas stored in the gas tank (70) is supplied to the keg (60) through the supply pipe (71), thereby pressurizing the juice stored in the keg (60) so that the juice is supplied to the injection part (12) of the housing (10) through the supply pipe (61).

[0038] Then, the juice extracted supplied to the injection part (12) of the housing (10) is supplied to the extension tube (20), and then supplied to the filter body (41) through the inlet through hole (41b) of the filter body (40). The juice extracted inside the filter body (41) passes through the discharge through hole (41a) and the filter member (42), and after the residue contained in the juice extracted is filtered out, it is discharged to the inlet part (31) of the extension tube (20), and then discharged to the discharge part (13) and discharge port (14) of the housing (10) through the connection hole (32a) of the extension tube (20).

[0039] And, if residue accumulates inside the filter body (40), as shown in FIG. 4, the lid (50) can be opened, the filter body (40) can be separated, and the filter container (41) can be replaced.

[0040] The filtration device configured in this manner comprises a filtration unit (A) equipped with a filter body (40) inside, a keg (60) in which juice is stored inside and which is connected to the filtration unit (A) through a supply pipe (61), and a gas tank (70) connected to the keg (60) through a supply pipe (71) to supply high-pressure CO2 gas to the keg (60), and the high-pressure CO2 gas supplied from the gas tank (70) is used to pressurize the juice stored in the keg (60) and supply it to the filtration unit (A).

[0041] Therefore, even if residue of the juice accumulates on the filter body (40) provided in the filtration unit (A), the juice is pressurized by the pressure of the high-pressure CO2 gas supplied by the gas tank (70), so that the juice is forced to pass through the filter body (40), thereby effectively removing the residue of the juice and effectively removing the bitter taste caused by the residue, and preventing the filtration time from becoming long because the juice cannot pass through the filter body (40) due to the residue.

[0042] In addition, since the above-mentioned juice is pressurized by CO2 gas, contact between the juice and oxygen in the air is minimized, which has the advantage of preventing the juice from oxidizing.

[0043] And, the above filtration unit (A) is configured in a tubular shape extending in the front and rear directions, with an outlet (14) formed at the rear end and divided into a front injection part (12) and a rear discharge part (13) by a plate (11) provided in the middle part, a housing (10), an extension tube (20) extending upwardly inclined from the upper surface of the housing (10) to be connected to the injection part (12), a filter tube (30) extending from the inside of the extension tube (20) to the discharge part (13), a filter body (40) coupled to the top of the filter tube (30), and a lid (50) coupled to the top of the extension tube (20), so that the juice supplied to the housing (10) passes through the filter body (40) and is discharged to the filter tube (30).

[0044] Therefore, the residue contained in the juice is filtered as it is discharged from the inside of the filter body (40) to the outside, so the residue remains inside the filter body (40), and there is an advantage that the residue can be easily removed by opening the lid (50) and separating the filter body (40).
