Description
Automatic hot dog fryer
[0001] The present invention relates to an automatic hot dog fryer, and more specifically, to an automatic hot dog fryer that fries hot dogs while moving them and retrieves the hot dogs when frying is finished.
[0002] Originally, a hot dog is a type of Western food made by splitting a long bun in half lengthwise, inserting a hot sausage, and spreading butter and mustard sauce on it. In other words, it refers to a long hamburger with a sausage instead of ham.
[0003] However, in South Korea, a hot dog refers to a long sausage skewered with a wooden stick, wrapped in dough, and deep-fried. Below, the hot dog is described as the latter, that is, a Korean-style food.
[0004] To make a hot dog, first, skewer a long sausage onto a wooden stick, then form a dough made of flour on the outside of the sausage, and then fry it in cooking oil.
[0005] At this time, since the worker cannot continuously hold the wooden stick, the means for inserting the wooden stick of the hot dog in the conventional hot dog frying device is provided in a fixed form. That is, the conventional hot dog frying device has a square steel frame structure, and the means for inserting the wooden stick of the hot dog is fixed to the inner wall.
[0006] However, conventional hot dog frying devices have a fixed structure of a simple oil tank type, so not only the task of inserting the hot dogs but also the task of removing the fried hot dogs must be performed manually, which has caused problems such as cumbersome and inconvenient work and reduced productivity.
[0007] To solve these problems, a hot dog frying device capable of automatically performing a series of operations such as inserting a hot dog in batter form to fry it in oil and then removing the fully fried hot dog has been disclosed in Korean Registered Patent No. 10-1768621 (Title of Invention: Hot Dog Frying Device), which is illustrated in FIG. 1 and FIG. 2.
[0008] The above hot dog frying device comprises: a main cabinet (110); a horizontal hot dog moving frying unit (120) horizontally positioned on one side of the main cabinet (110) and filled with oil into which battered hot dogs are immersed and fried; an inclined hot dog moving discharge unit (130) connected to the horizontal hot dog moving frying unit (120) but positioned at a certain angle inclined with respect to the horizontal hot dog moving frying unit (120) so as not to have oil, and through which fried hot dogs fried in oil within the horizontal hot dog moving frying unit (120) are discharged; and a pair of chains (145) rotatably coupled in a closed-loop form on both sides of the horizontal hot dog moving frying unit (120). A chain rotation drive unit (140) provided on one side of the main cabinet (110) and connected to the pair of chains (145), and rotating the pair of chains (145); a plurality of movable bars (148) having both ends connected to the pair of chains (145) and moving along the chains (145); a plurality of movable stick holders (150a) connected to the movable bars (148) and into which wooden sticks provided in hot dogs are inserted; It is characterized by including a controller (180) that controls the operation of the chain rotation drive unit based on a predetermined input signal from the input unit, and further including a hot dog extraction fixing bar (171) that is positioned parallel to the moving bar (148) in the upper area of the inclined hot dog moving discharge unit (130) and is configured to catch the wooden stick of the fried hot dog moving along the chain (145) and detach from the moving stick holder (150a) to be extracted.
[0009] The above hot dog frying device has the effect of improving productivity by automatically carrying out a series of operations, such as inserting a hot dog in batter form to fry it in oil and then removing the fully fried hot dog.
[0010] When the fried hot dog is fully fried, the chain (145) moves, and when the wooden stick of the fried hot dog inserted into the movable stick holder (150a) catches on the fixed hot dog extraction fixing bar (171), the wooden stick is detached from the movable stick holder (150a) and falls, thereby being extracted. At this time, when the wooden stick of the fried hot dog catches on the fixed hot dog extraction fixing bar (171), the wooden stick tilts away from the movable stick holder (150a), and when the fixing force of the wooden stick fixed to the movable stick holder (150a) becomes weaker than the weight of the hot dog, the hot dog falls downward and is extracted.
[0011] However, when the fried hot dog is removed after frying, the chain (145) moves and the wooden stick of the fried hot dog inserted into the movable stick holder (150a) gets caught on the fixed hot dog removal fixing bar (171), causing it to detach from the movable stick holder (150a) and be removed. However, if the fixing force of the movable stick holder (150a) to fix the wooden stick is increased, there is a problem that the wooden stick does not easily detach. Therefore, if the wooden stick does not detach from the movable stick holder (150a), the hot dog removal fixing bar (171) gets caught on the batter of the fried hot dog, causing deformation of the shape of the fried hot dog and a decrease in product value.
[0012] In addition, when the hot dog falls, the batter of the fried hot dog may collide with the movable hot dog stand (172), which may cause deformation of the shape of the fried hot dog, and there is a problem that the commercial value is reduced due to the deformation.
[0013] In addition, if the fixing force of the stick is reduced so that the wooden stick can easily detach from the movable stick holder (150a), there is a problem that the wooden stick detaches from the movable stick holder (150a) due to buoyancy during the bouncing process.
[0014] Therefore, there is a need to develop a hot dog fryer that maintains marketability by ensuring the fixing force of the movable stick holder (150a) for fixing the wooden stick, while preventing deformation of the shape of the fried hot dog when the fried hot dog is ejected, so that the wooden stick of the fried hot dog can be stably removed from the movable stick holder (150a).
[0015] The objective of the present invention is to provide an automatic hot dog fryer that enables automatic frying of a fried hot dog, while simultaneously preventing deformation of the shape of the fried hot dog and facilitating the removal of the wooden stick from the stick holder, thereby enabling the extraction of the fried hot dog.
[0016] Another objective of the present invention is to provide an automatic hot dog fryer that automatically performs the frying of hot dogs and facilitates the removal of batter residue to reduce oil contamination.
[0017] An automatic hot dog fryer according to an embodiment of the present invention comprises: a main body (10); an oil receiving section (20) provided in the lower part of the main body (10) and receiving oil; a heating section (30) provided in the oil receiving section (20) and heating the received oil; a pair of chains (40) provided in the upper part of the oil receiving section (20), forming an endless track and spaced apart in parallel to the left and right; a chain rotation section (50) rotatably provided in the main body (10) and composed of a driving sprocket (51) and a plurality of driven sprockets (52) that engage with each of the chains (40) to rotate the chains (40); a rotation motor (60) that rotates the driving sprocket (51); and a fixed bar (70) arranged at a certain interval along the track direction of the chains (40), with both ends fixed to the chains (40) respectively, and rotated in conjunction with the rotation of the chains (40) to be conveyed. A stick fixing part (80) that allows the wooden stick (1c) inserted into the sausage (1a) to be fixed so that the hot dog (1) is erected upright with the dough part (1b) surrounding the sausage (1a) facing downward and is submerged in the cooking oil contained in the cooking oil receiving part (20) and fried, and the wooden stick (1c) is detachable; The device is characterized by comprising: a rotating plate (90) installed on the outer upper portion of the cooking oil receiving portion (20) at the part where the fried hot dog comes out of the cooking oil received in the cooking oil receiving portion (20), and by rotation opposite to the rotation direction of the rotating motor (60), the upper surface contacts the hot dog (1) and separates the wooden stick (1c) fixed to the stick fixing portion (80), and supports the extracted hot dog (1) and slides it to the outside of the main body (10) by means of the inclined upper surface by rotation; a rotating plate rotation driving portion (100) that drives the rotating plate (90) to rotate; and a hot dog recovery portion (110) provided at the lower portion of the rotating plate (90), in which the hot dog (1) extracted and slides it by the rotation of the rotating plate (90) falls and is recovered.
[0018] In addition, the stick fixing part (80) is preferably made of a pair of metal pieces comprising an insertion part (81) provided at the outer end and into which a wooden stick (1c) is inserted by opening, an elastic fixing part (82) extending from the insertion part (81) to fix the inserted wooden stick (1c) by elastic force, and a fixing bar fixing part (83) extending from the elastic fixing part (82) and fixed on the opposite side of the conveying direction of the fixing bar (70).
[0019] Additionally, the chain (40) forms an endless track in the shape of a right-angled square having a hypotenuse (41), the hypotenuse (41) is located at the part where the rotating plate (90) is installed, the lower part of the hypotenuse (41) is located at the outer upper part of the cooking oil receiving part (20), and the upper part of the hypotenuse (41) is located at the outer upper part of the cooking oil receiving part (20), so that when the fixing bar (70) is transported by the hypotenuse (41) of the chain (40), the hot dog (1) fixed to the stick fixing part (80) is transported at an angle, and when the wooden stick (1c) fixed to the stick fixing part (80) is separated by the rotation of the rotating plate (90) to extract the hot dog, the rotating plate (90) is rotated and tilted so that it descends to the outside of the main body, and is close to the main body (10) around the axis of the rotating plate (90). It is preferable that the side end portion of the dough portion (1b) of the hot dog (1) first comes into contact with the upper surface of one side of the rotating plate (90), and as the rotating plate (90) is further rotated and the inclination becomes increasingly larger, the side of the dough portion (1b) of the hot dog (1) comes into contact with the upper surface of one side of the rotating plate (90), causing the wooden stick (1c) fixed to the stick fixing part (80) to be separated, and the extracted hot dog (1) slides to the upper surface of the other side of the rotating plate (90) due to the inclination of the rotating plate (90) and falls to the hot dog recovery part (110) to be recovered.
[0020] Additionally, it is preferable that the rotational speed of the rotary motor (60) for conveying the chain (40) is smaller than the rotational speed of the rotary plate (90) by the rotary plate rotation drive unit (100).
[0021] The above-described rotating plate drive unit (100) may be composed of a rotating plate drive sprocket (101) that rotates in conjunction with the driven sprocket (52), a rotating plate driven sprocket (102) that is provided on the rotation axis of the rotating plate (90) and rotates in conjunction with the rotating plate (90), and a rotating plate rotation chain (103) that engages with the rotating plate drive sprocket (101) and the rotating plate driven sprocket (102) to transmit rotational force from the rotating plate drive sprocket (101) to the rotating plate driven sprocket (102).
[0022] In the automatic hot dog fryer according to an embodiment of the present invention, the wooden stick (1c) fixed to the stick fixing part (80) is separated by the upper surface coming into contact with the hot dog (1) by the rotation of the rotating plate (90), thereby making it easy to extract the hot dog (1) and preventing deformation of the shape of the fried hot dog. In addition, the extracted hot dog (1) is supported by the rotating plate (90) and slides outward from the main body (10) by the inclined upper surface due to rotation, thereby acting as a cushion, preventing deformation of the shape of the fried hot dog caused by conventional falling collisions, and thus preventing a decrease in product value due to deformation.
[0023] In addition, since the wooden stick (1c) can be easily separated from the stick fixing part (80) by a small contact force between the end portion of the hot dog (1) dough part (1b) and the rotating plate (90), the deformation of the hot dog (1) dough part (1b) by the rotating plate (90) is minimized, thereby preventing a decrease in product value due to deformation.
[0024] In addition, since the frying residue generated when frying hot dogs can be filtered out while frying, the taste and quality of the fried hot dogs can be improved.

[0038] An automatic hot dog fryer according to an embodiment of the present invention comprises: a main body (10); an edible oil receiving part (20); a heating part (30); a chain (40); a chain rotating part (50); a rotating motor (60); a fixed bar (70); a stick fixing part (80); a rotating plate (90); and a hot dog retrieval part (110).
[0039] The main body (10) is in the form of a square frame as shown in FIGS. 4 to 6, and is provided with an edible oil receiving portion (20) in the lower part. The main body (10) can be fixed to the ground, and wheels (not shown) can be provided in the lower part to allow movement.
[0040] The above edible oil receiving portion (20) is provided in the lower part of the main body (10) and edible oil is received.
[0041] The heating unit (30) (see FIG. 7) is provided in the edible oil receiving unit (20) and serves to heat the edible oil contained therein.
[0042] The above chain (40) is formed as a pair, is provided on the upper part of the edible oil receiving part (20), forms an endless track, and is spaced apart parallel to each other on the left and right.
[0043] The chain rotation unit (50) is rotatably provided on the main body (10) and consists of a driving sprocket (51) and a plurality of driven sprockets (52) that engage with each of the chains (40) to rotate the chains (40). The driving sprocket (51) and the plurality of driven sprockets (52) are each formed as a pair, and it is preferable to each have a connecting shaft (53) (see FIG. 13) that connects the sprockets formed as a pair to each other so that they rotate in the same manner.
[0044] It is acceptable to provide a known tension adjustment part in the form of a sprocket for adjusting the tension of the above chain (40).
[0045] The above rotary motor (60) (see FIG. 6) serves to rotate the drive sprocket (51) to rotate the chain (40).
[0046] The above rotary motor (60) may have the drive sprocket (51) directly connected to the motor shaft. Since the rotational speed of the chain (40) is low, it is preferable to provide a linkage sprocket that rotates in conjunction with the drive sprocket (51) and to reduce the speed by using a drive gear and a power transmission chain to rotate the drive sprocket (51) on the motor shaft.
[0047] The above fixed bar (70) (see FIG. 7, FIG. 14) is arranged at regular intervals along the track direction of the chain (40), and both ends are fixed to the chain (40) respectively and are rotated in conjunction with the rotation of the chain (40) to be transported.
[0048] The stick fixing part (80) is formed to protrude in the same line as the track of the chain (40) on the opposite side of the conveying direction of the fixing bar (70), and fixes the wooden stick (1c) inserted into the sausage (1a) so that the hot dog (1) is upright with the dough part (1b) surrounding the sausage (1a) facing downward and is submerged in the cooking oil contained in the cooking oil receiving part (20) to be fried, and the fixing and detachment of the wooden stick (1c) are possible.
[0049] The above-mentioned rotating plate (90) is installed on the outer upper part of the cooking oil receiving part (20) where the fried hot dog comes out of the cooking oil received part (20), and by rotating in the opposite direction to the rotation direction of the rotating motor (60), the upper surface comes into contact with the hot dog (1) and separates the wooden stick (1c) fixed to the stick fixing part (80), and supports the extracted hot dog (1) and slides it outwardly to the outside of the main body (10) by the inclined upper surface by rotation.
[0050] The above-mentioned rotating plate drive unit (100) serves to rotate the above-mentioned rotating plate (90).
[0051] The above hot dog retrieval unit (110) (see FIG. 4) is provided at the bottom of the rotating plate (90), and the hot dog (1) that is ejected and slid-transported by the rotation of the rotating plate (90) falls and is received.
[0052] The automatic hot dog fryer of the present invention, configured as described above, separates the wooden stick (1c) fixed to the stick fixing part (80) by the upper surface coming into contact with the hot dog (1) through the rotation of the rotating plate (90), thereby making it easy to extract the hot dog (1) and preventing deformation of the shape of the fried hot dog. In addition, the extracted hot dog (1) is supported by the rotating plate (90) and slides outward from the main body (10) by the inclined upper surface due to rotation, thereby acting as a cushion, which prevents deformation of the shape of the fried hot dog caused by conventional falling collisions, and thus prevents a decrease in product value due to deformation.
[0053] The present invention may be provided with a control unit (150) for controlling the operation of the rotary motor (60), the operation of the heating unit (30), and the rotational operation of the rotating plate (90).
[0054] The above stick fixing part (80) uses a known structure that is opened by inserting a wooden stick, fixed by elasticity, and separated by separation by pulling.
[0055] The stick fixing part (80) above may use a known structure consisting of a pair of metal pieces, as shown in FIG. 7, comprising an insertion part (81) provided at the outer end and into which a wooden stick (1c) is inserted by opening, an elastic fixing part (82) extending from the insertion part (81) to fix the inserted wooden stick (1c) by elastic force, and a fixing bar fixing part (83) extending from the elastic fixing part (82) and fixed on the opposite side of the conveying direction of the fixing bar (70).
[0056] In addition, in order to facilitate the extraction of the hot dog (1) by the rotation of the rotating plate (90), it is preferable that the chain (40) in the part adjacent to the rotating plate (90) be inclined so that the hot dog (1) is transported at an angle.
[0057] To this end, the chain (40) forms an endless track in the shape of a rectangular rectangle having a hypotenuse (41) (see FIG. 6, FIG. 8 to FIG. 12), the hypotenuse (41) is located at the part where the rotating plate (90) is installed, the lower part of the hypotenuse (41) is located at the outer upper part of the cooking oil receiving part (20), and the upper part of the hypotenuse (41) is located at the outer upper part of the cooking oil receiving part (20), so that when the fixing bar (70) is transported by the hypotenuse (41) of the chain (40), the hot dog (1) fixed to the stick fixing part (80) is transported at an angle.
[0058] At this time, when removing the hot dog by separating the wooden stick (1c) fixed to the stick fixing part (80) by the rotation of the rotating plate (90), the rotating plate (90) is rotated and tilted so as to descend to the outside of the main body, and the side end portion of the dough portion (1b) of the hot dog (1) first comes into contact with the upper surface of one side close to the main body (10) around the axis of the rotating plate (90). As the rotating plate (90) is further rotated and the tilt becomes increasingly larger, the side of the dough portion (1b) of the hot dog (1) comes into contact with the upper surface of one side of the rotating plate (90), and the wooden stick (1c) fixed to the stick fixing part (80) is separated. The removed hot dog (1) slides to the upper surface of the other side of the rotating plate (90) due to the tilt of the rotating plate (90) (see FIG. 12), falls to the hot dog recovery part (110), and is recovered. It is desirable.
[0059] When the rotating plate (90) is rotated and tilted so as to descend to the outside of the main body, the side upper surface near the main body (10) and the side end portion of the dough portion (1b) of the hot dog (1) come into contact for the first time around the axis of the rotating plate (90) (see FIGS. 8 and 9). When the rotating plate (90) is further rotated and the tilt becomes increasingly larger, a slight force is applied to the end portion of the dough portion (1b) of the hot dog (1) that is in contact with the rotating plate (90). A very large force is applied to the wooden stick (1c) that is far from the end portion of the dough portion (1b) of the hot dog (1) due to torque, and the wooden stick (1c) is immediately separated from the stick fixing portion (80) (see FIGS. 10 and 11). In this way, the wooden stick (1c) can be easily separated from the stick fixing part (80) even by a small contact force between the end portion of the hot dog (1) dough portion (1b) and the rotating plate (90), thereby minimizing deformation of the hot dog (1) dough portion (1b) by the rotating plate (90), so that the decrease in product value due to deformation can be prevented.
[0060] In addition, it is preferable that the rotational speed of the rotary motor (60) for conveying the chain (40) is smaller than the rotational speed of the rotary plate (90) by the rotary plate rotation drive unit (100).
[0061] The reason the rotational speed of the rotary motor (60) for conveying the chain (40) is less than the rotational speed of the rotary plate (90) driven by the rotary plate rotation drive unit (100) is to allow the wooden stick (1c) to be separated from the stick fixing unit (80) by the torque caused by contact with the end portion of the dough portion (1b) of the hot dog (1) due to the rotation of the rotary plate (90).
[0062] If the rotational speed of the rotary motor (60) for conveying the chain (40) is greater than the rotational speed of the rotary plate (90) driven by the rotary plate rotation drive unit (100), contact with the end portion of the dough portion (1b) of the hot dog (1) is not generated by the rotation of the rotary plate (90), making it impossible to extract the hot dog (1).
[0063] In addition, when the rotating plate (90) extracts a hot dog by rotation, it is also necessary to adjust the rotation speed of the rotating motor (60) so that the chain (40) can pass along the lower side of the rotating plate (90) close to the main body (10) without interference occurring where the next hot dog to be extracted collides with the rotating plate (90), centering on the axis of the rotating plate (90).
[0064] Next, when the hot dog to be ejected passes along the lower side of the rotating plate (90) near the main body (10) around the axis of the rotating plate (90) without any interference occurring where it collides with the rotating plate (90), the other side of the rotating plate (90) that has slid the hot dog is rotated to eject the hot dog.
[0065] In addition, the above-mentioned rotating plate drive unit (100) may be rotated by being equipped with a separate rotating motor, but it is preferable to rotate the rotating plate (90) using power from a rotating motor (60) for rotating the drive sprocket (51).
[0066] To this end, the rotary plate rotation drive unit (100) is configured such that, as shown in FIG. 13, the rotary plate drive sprocket (101) rotates in conjunction with the driven sprocket (52), the rotary plate driven sprocket (102) is provided on the rotation axis of the rotary plate (90) and rotates in conjunction with the rotary plate (90), and the rotary plate rotation chain (103) is engaged with the rotary plate drive sprocket (101) and the rotary plate driven sprocket (102) to transmit rotational force from the rotary plate drive sprocket (101) to the rotary plate driven sprocket (102).
[0067] At this time, the rotational speed of the rotary motor (60) for conveying the chain (40) is adjusted to be greater than the rotational speed of the rotary plate (90) by the rotary plate rotation drive unit (100) by using the gear ratio of the driven sprocket (52) linked with the rotary plate drive sprocket (101).
[0068] In addition, the present invention is preferably capable of filtering and removing frying residue generated when frying hot dogs.
[0069] To this end, the present invention is provided with a filter plate (120) and a frying residue removal unit (130).
[0070] As shown in FIGS. 14 and 15, the filter plate (120) is arranged along the track direction of the chain (40), with both ends fixed to the chain (40) and transported by rotation in conjunction with the rotation of the chain (40). When the chain (40) is positioned at the bottom, it comes into contact with the oil surface of the cooking oil contained in the cooking oil receiving portion (20) and serves to filter out frying residue floating on the oil surface. At least one filter plate is provided. At this time, it is preferable that the filter plate (120) has a plurality of cooking oil passage holes through which cooking oil can pass in order to reduce the flow of cooking oil when the chain (40) is transported by rotation.
[0071] The above frying residue removal unit (130) is provided at the lower part of the chain (40) located at the top or at the side of the chain (40) before the hot dog (1) to be fried enters the cooking oil contained in the cooking oil receiving unit (20), and serves to remove frying residue filtered by the filter plate (120) from the filter plate (120).
[0072] At this time, the filter plate (120) is hinge-connected to the chain (40) at the fixed portion so that no interference occurs between them, allowing the chain (40) to rotate smoothly when removing frying residue by the frying residue removal part (130).
[0073] The above frying residue removal unit (130) is preferably composed of a brush rotation shaft (131), a brush rotation shaft rotation drive unit (not shown), and a frying residue receiving unit (132), as shown in FIG. 16.
[0074] The brush rotation axis (131) is fixed to the main body (10) and is installed horizontally perpendicular to a pair of chains (40), and is provided with a brush (131a) on its outer circumference, and is installed so that the brush (131a) contacts the filter plate (120).
[0075] The brush rotation axis rotation drive unit above serves to rotate the brush rotation axis (131).
[0076] The above brush rotation shaft rotation drive unit may be equipped with a separate rotation motor and may be rotated in conjunction with one of the above driven sprockets (52).
[0077] The above frying residue receiving portion (132) is provided at the lower part of the brush rotation axis (131) and receives frying residue that is removed from the filter plate (120) and dropped by the rotation of the brush (131a).
[0078] In this way, the present invention allows for frying hot dogs while filtering out frying residue generated when frying hot dogs, thereby improving the taste and quality of the fried hot dogs.
