Description

Oil removal device using heat and centrifugal force

[0001] The present invention relates to an oil removal device using heat and centrifugal force, and more specifically, to an oil removal device that can remove oil more efficiently than a conventional method of removing oil using only centrifugal force by removing oil using centrifugal force while applying heat.

[0002] There are many different types of cuisine, and among them, fried food is the most popular. Fried food refers to foods like fish, meat, or vegetables coated in flour and deep-fried in oil. Restaurants like fast food restaurants, chicken restaurants, and fried food specialty stores offer this type of fried food, and the number of such restaurants has been increasing exponentially in recent years.

[0003] Restaurants that serve these fried foods usually use gravity to remove the oil from the fried food, so it is impossible to completely remove the oil from the fried food.

[0004] Domestic Patent Publication No. 10-1146881 discloses a frying device in which a central axis is fixed to a basket, food is fried by lowering the central axis and entering the oil tank, and when the frying is complete, the central axis is raised to remove the food from the oil tank.

[0005] However, since the above fryer simply removes food from the oil tank, oil remains in the food, which reduces the taste and quality.

[0006] To improve this, Republic of Korea Utility Model Application No. 20-2002-0034079 disclosed a deoiler for fried food using centrifugal force due to rotation, but it had the problem of low oil removal efficiency.

[0007] Accordingly, the technical problem of the present invention was conceived from this point, and the purpose of the present invention is to provide an oil removal device capable of efficient oil removal using heat and centrifugal force.

[0008] In addition, the present invention provides an oil removal device that can minimize the oil separated from fried food from being absorbed into other fried food by removing oil using a plurality of baskets formed in steps.

[0009] According to one embodiment of the present invention for realizing the above-described object, an oil removal device is provided, including: a main body; a lid for opening and closing the upper portion of the main body; a basket at least part of which is installed inside the main body, the upper portion of which is open, and which has two or more discharge ports capable of discharging oil on the lower surface and the peripheral surface; and a rotating body connected to the lower surface of the basket and driven by a driving motor to rotate the basket.

[0010] The above lid includes a lid body and a heating part, the heating part is formed on one side of the lid body in an inward direction of the main body, the heating part includes a heating surface, and the heating surface can be formed in a shape inclined toward the inside of the main body.

[0011] The above lid may additionally include a vent.

[0012] The above basket includes a first-stage basket and a second-stage basket formed inside the first-stage basket by penetrating the lower surface of the first-stage basket, and the first-stage basket and the second-stage basket are formed to be stepped from each other in the height direction, and a gap between the upper part of the first-stage basket and the lid body may be smaller than a gap between the upper part of the second-stage basket and the lid body.

[0013] The first stage basket may include a first discharge port group formed with a plurality of first discharge ports on the circumferential surface, and a second discharge port group formed with a plurality of second discharge ports on the lower surface.

[0014] The second-stage basket may include a third discharge port group formed with a plurality of third discharge ports on a circumferential surface at a position corresponding horizontally to the circumferential surface of the first-stage basket, a fifth discharge port group formed with a plurality of fifth discharge ports on a circumferential surface other than the circumferential surface at a position corresponding horizontally to the circumferential surface of the first-stage basket, and a fourth discharge port group formed with a plurality of fourth discharge ports on a lower surface.

[0015] The above basket may include a joining groove formed in a lower surface of the second-stage basket so that one end of the rotating body can be inserted inward.

[0016] The above-mentioned rotating body may include a boss that is coupled to the above-mentioned coupling groove and connected to the driving shaft of the above-mentioned driving motor.

[0017] According to embodiments of the present invention, an oil removal device using heat and centrifugal force can efficiently remove oil using heat and centrifugal force, thereby improving the crispy texture and taste of fried food itself and contributing to a healthy diet by reducing oil intake.

[0018] In addition, by removing oil using a plurality of baskets formed in steps, it is possible to minimize the oil separated from the fried food from being absorbed into other fried foods.

[0019] However, the effects of the present invention are not limited to the above effects, and may be expanded in various ways without departing from the spirit and scope of the present invention.

[0020] Figure 1 illustrates an oil removal device according to one embodiment of the present invention.

[0021] Figure 2 is a perspective view showing an oil removal device according to one embodiment of the present invention.

[0022] Figure 3 is a cross-sectional view showing an oil removal device according to one embodiment of the present invention.

[0023] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0024] The present invention is susceptible to various modifications and takes various forms. Specific embodiments are illustrated in the drawings and described in detail herein. However, this is not intended to limit the present invention to specific disclosed forms, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0025]

[0026] FIG. 1 schematically illustrates an oil removal device according to one embodiment of the present invention, FIG. 2 is a perspective view of the oil removal device, and FIG. 3 is a cross-sectional view of the oil removal device.

[0027] Hereinafter, an oil removal device according to one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0028] The above oil removal device includes a main body (100), a lid (200), a basket (300), and a rotating body (400).

[0029] The main body (100) is formed in the form of a structure with an installation space provided so that a basket (300), a rotating body (400), etc. can be installed inside.

[0030] The upper part of the main body (100) is formed to be open so that fried food can be easily put inside, and a lid (200) can be installed to be rotatable so that the upper part can be opened and closed. Although not shown in the drawing, a locking device may be installed on the lid (200) so that the lid (200) can be selectively fixed to the main body (100).

[0031] The lid (200) may include a lid body (210) and a heating unit (220).

[0032] The lid body (210) closes the upper part of the open main body (100) and may have a circular shape.

[0033] A heating unit (220) is formed at one end of the lid body (210) to continuously apply heat while removing oil from fried food contained in the basket (300), thereby preventing the oil from solidifying. Oil contains saturated fatty acids and unsaturated fatty acids, and saturated fatty acids, which have a melting point higher than room temperature, do not melt at room temperature and easily solidify. Since fried food, which is mainly used for removing oil, is fried at a high temperature, a large amount of saturated fatty acids are produced, and thus the saturated fatty acid content is higher than that of other foods. Therefore, the efficiency of removing oil from fried food is greatly reduced at room temperature. To prevent this, the present invention forms a heating unit (220) at one end of the lid body (210).

[0034] In addition, the heating unit (220) includes a heating surface (230), and the heating surface (230) is characterized by being formed in a shape that is inclined inwardly toward the inside of the main body (100). This is to minimize the gap with the fried food accommodated in the basket (300). The shape of the heating unit (220) is not limited, and as described later, it satisfies the configuration in which it is arranged to be inclined in consideration of the step height of a plurality of baskets (310, 320) configured to be stepped. That is, the heating unit (220) may be formed as a heating surface (230) in a downwardly inclined cone shape as in the present embodiment, and may be formed in a stepped shape so as to correspond to the step shapes of the first and second stage baskets (310, 320).

[0035] The lid (200) may additionally include a vent (240). The vent (240) is a hole that can exhaust oil vapor and water vapor that may be generated when removing oil from the inside of the main body (100) to the outside. The vent (240) may include a blower fan (241) that blows wind from the inside of the main body (100) toward the outside. By removing oil while discharging oil vapor and water vapor through the vent (240), it is possible to minimize oil separated from fried food from being absorbed back into the fried food.

[0036] The basket (300) is installed inside the main body (100), has an open upper portion, and has two or more discharge ports on the lower surface and the circumferential surface to discharge oil.

[0037] Preferably, the basket (300) may be composed of a first-stage basket (310) and a second-stage basket (320). The second-stage basket (320) is formed by penetrating the lower surface of the first-stage basket (310), and the first-stage basket (310) and the second-stage basket (320) are formed to be stepped from each other in the height direction. The gap between the upper part of the first-stage basket (310) and the lid body (210) is smaller than the gap between the upper part of the second-stage basket (320) and the lid body (210).

[0038] The first stage basket (310) may include a first discharge port group (340) formed with a plurality of first discharge ports (341) on the circumferential surface, and a second discharge port group (350) formed with a plurality of second discharge ports (351) on the lower surface.

[0039] The second-stage basket (320) may include a third discharge port group (360) formed with a plurality of third discharge ports (361) on the circumferential surface corresponding horizontally to the circumferential surface of the first-stage basket (310), a fifth discharge port group (380) formed with a plurality of fifth discharge ports (381) on the remaining circumferential surface excluding the circumferential surface where the third discharge port group (360) is formed, and a fourth discharge port group (370) formed with a plurality of fourth discharge ports (371) on the lower surface.

[0040] The basket (300) formed in this form can minimize the oil being reabsorbed into the fried food accommodated in the first-stage basket (310) by allowing most of the oil separated from the fried food accommodated in the second-stage basket (320) to be discharged through the fifth discharge port group (380) due to the above-mentioned steps.

[0041] Specifically, a portion of the oil separated from the fried food contained in the second-stage basket (320) is discharged through the circumferential surface, and a portion is discharged through the fourth discharge port group (370) formed on the lower surface. At this time, due to the step, a fifth discharge port group (380) is formed on the circumferential surface of the second-stage basket (320) that does not correspond horizontally to the circumferential surface of the first-stage basket (310). The larger the step, the larger the area of ​​the fifth discharge port group (380) can be.

[0042] Oil discharged through the first discharge port group (340) and the second discharge port group (350) of the first stage basket (310) by centrifugal force is rarely reabsorbed into other fried foods, but since the second stage basket (320) is formed inside the first stage basket (320), oil separated from the fried foods received in the second stage basket (320) can be reabsorbed into the fried foods received in the first stage basket (320) when discharged through the third discharge port group (360). Therefore, the greater the difference in steps between the first stage basket (310) and the second stage basket (320), the more fifth discharge ports (381) that do not discharge oil to the first stage basket (310) can be included.

[0043] In other words, since the oil removal device of the present invention removes oil by centrifugal force rather than gravity, when using a basket (300) formed without steps, oil separated from fried food located in the center of the basket (300) may be reabsorbed into fried food located in the outer part of the basket (300). In order to minimize this, the amount of fried food should be accommodated in the basket (300) so that as little fried food as possible is not located in the center of the basket (300). However, this can be seen as reducing the amount of fried food that can be accommodated at one time, which lowers the efficiency of the device.

[0044] The stepped baskets (300) accommodate the same amount of fried food, but since the first-tier basket (310) has no fried food at all in the center, the oil separated from the fried food is hardly reabsorbed into other fried food. In addition, since the second-tier basket (320) accommodates a small amount of fried food, the oil separated from the fried food located in the center is more in the outer portion than in the center, so that the oil separated from the fried food located in the center is minimized from being reabsorbed into other fried food located in the outer portion. In addition, most of the oil separated from the fried food accommodated in the second-tier basket (320) due to the steps is discharged through the fifth discharge ports (381) that do not discharge oil to the first-tier basket (310).

[0045] As described above, the heating surface (230) of the heating unit (220) is configured to have a cone shape and slope downward inwardly of the main body (100). Even when the basket (300) is formed in steps, the height distance between the fried food accommodated in the first-stage basket (310) and the heating surface (230) and the height distance between the fried food accommodated in the second-stage basket (320) and the heating surface (230) are similar, so that almost all fried food can be evenly heated. Therefore, the oil removal efficiency can be further improved.

[0046] The rotating body (400) is connected to the lower surface of the basket (300) and can be rotated by a driving motor (not shown) to rotate the basket (300). Preferably, the basket (300) may include a joining groove (330) that is recessed into the lower surface of the second-stage basket (320) so that one end of the rotating body (400) can be inserted inward, and the rotating body (400) may include a boss (410) that is connected to the joining groove (330) and the driving shaft of the driving motor.

[0047] Due to this, the second stage basket (320) can reduce the amount of fried food located in the center portion by the joining groove (330) formed in the center portion. In addition, by inserting the boss (410) into the inside of the second stage basket (320), the rotational force of the driving motor can be better transmitted to the basket (300).

[0048]

[0049] Hereinafter, the operation of an oil removal device according to one embodiment of the present invention having the above configuration will be described in detail.

[0050] An appropriate amount of fried food is evenly placed in the first-stage basket (310) and the second-stage basket (320), and positioned so that the joining groove (330) of the second-stage basket (320) is joined with the boss (410) of the rotating body (400). At this time, when the basket (300) is filled with fried food, the oil separated from the fried food accommodated in the second-stage basket (320) can be reabsorbed into the fried food accommodated in the first-stage basket (310) through the third discharge port group (360), so that an appropriate amount of fried food is accommodated.

[0051] When the lid (200) is closed and the frying material is heated through the heating surface (230) of the heating element (220), and the basket (300) is rotated by the driving motor, oil is separated from the frying material by centrifugal force.

[0052] Oil separated from fried food contained in the first stage basket (310) is discharged through the first discharge port group (340) and the second discharge port group (350), and most of the oil separated from fried food contained in the second stage basket (320) is discharged through the fourth discharge port group (370) and the fifth discharge port group (380).

[0053] Due to this, efficient oil removal can be achieved by minimizing the oil separated from the fried food received in the second-stage basket (320) from being reabsorbed into the fried food received in the first-stage basket (310).
