Description

Technology Field

[0001] The invention relates to an automatic tanghulu manufacturing device and method, and more specifically, to an automatic tanghulu manufacturing device and method capable of automatically manufacturing tanghulu by automatically inserting a skewer into a fruit contained in a fruit holder, applying a sugar coating to the fruit with the skewer inserted therein, and then cooling the fruit. Background Technology

[0002] Tanghulu refers to a Chinese snack made by skewering fruits such as Shine Muscat grapes, tangerines, and strawberries, and coating them with sugar syrup that is mixed and heated in a specific ratio.

[0003] As Tanghulu has become popular nationwide, not only has the number of Tanghulu specialty shops increased, but the number of people buying ingredients to make it at home has also increased, and various recipes are being shared on the internet and platforms.

[0004] In the case of a tanghulu specialty store, the store hires a large number of employees to meet the supply volume for high demand, and there is a limit to obtaining high net profit due to labor costs.

[0005] In addition, sugar water is heated to a high temperature for use, which poses a risk of burns in stores or homes.

[0006] In other words, to sugar-coat fruit, solid sugar with a high melting point of 185°C is melted into a liquid state to produce sugar water; at this time, the sugar water not only maintains a high temperature but also has high viscosity.

[0007] When high-temperature sugar water splashes onto the skin during the process of making tanghulu, it causes a combination of scalding burns and contact burns. As a result, there is a problem in that even a single burn can lead to 2nd or 3rd degree burns, potentially requiring skin grafting.

[0008] Burns caused by such tanghulu are highly dangerous as they can occur not only during the production process but also during the processing of the sugar water. Prior art literature

[0038] First, the automatic tanghulu manufacturing device according to the present invention will be described as follows with reference to FIGS. 1 to 10.

[0039] First, as illustrated in FIGS. 1 and 2, the automatic tanghulu manufacturing device according to the present invention includes a tray mounting deck (D1), a transfer mounting deck (D2), a fruit mounting section (1000), a coating section (2000), a cooling section (3000), a loading section (4000), a driving section (5000), a mounting verification section (6000), and a control section (7000).

[0040] The above tray mounting deck (D1) has the fruit mounting section (1000), the coating section (2000), the cooling section (3000), the load section (4000), and the driving section (5000) arranged on its upper surface, and each component is stably supported from the ground and can be attached and detached, and a separate space is formed inside to accommodate the device and materials required for making tanghulu.

[0041] The above transfer mounting deck (D2) has the tray mounting deck (D1), the load section (4000), and the drive section (5000) arranged and combined on its upper surface, and performs the role of supporting each component and integrating them into one.

[0042] The fruit holder (1000) holds a fruit to be attached to a skewer, and specifically, the fruit holder (1000) includes a fruit receiving part (1100) and a fruit opening / closing cover (1200), which will be explained with reference to FIGS. 1 to 3 as follows.

[0043] The fruit receiving portion (1100) is formed in the shape of a tray with an open top surface, in which the fruit is received inside.

[0044] At this time, the fruit receiving section (1100) may be formed with a receiving section (1110) so that one fruit in one section can be received.

[0045] In addition, the surface of the fruit receiving portion (1100) facing the driving portion (5000) has a receiving portion mounting groove (1120) formed so that a skewer described later can be mounted thereon, and the skewer can move back and forth in the receiving portion mounting groove (1120).

[0046] The fruit opening / closing cover (1200) opens and closes the upper surface of the fruit receiving portion (1100) and is connected to one side of the fruit receiving portion (1100) and is configured with a hinge to rotate, and can open and close the upper surface of the fruit receiving portion (1100).

[0047] The fruit opening / closing cover (1200) normally keeps the internal space of the fruit receiving section (1100) closed, and opens it when the skewer moves, thereby minimizing dust from the outside entering the fruit receiving section (1100).

[0048] The automatic tanghulu manufacturing device according to the present invention may further include a fruit supply unit (1500), and the fruit supply unit (1500) may supply fruit to the fruit holder (1000).

[0049] For example, the fruit supply unit (1500) is positioned inside the tray mounting deck (D1) and is positioned below the fruit receiving unit (1100). At the same time, the fruit receiving unit (1100) is configured so that its lower part can be opened and closed, and is connected to the fruit supply unit (1500) so that the fruit supply unit (1500) can supply fruit to the fruit receiving unit (1100) from the lower direction of the fruit receiving unit (1100).

[0050] Again, referring to FIGS. 1 and 2, the coating portion (2000) contains a coating material for sugar-coating the fruit fixed to the skewer, and the coating portion (2000) includes a coating material receiving portion (2100), a coating material delivery pipe (2200), a delivery opening / closing valve (2300), and a coating material opening / closing cover (2400), and is described as follows with reference to FIGS. 2 and 4.

[0051] As shown in FIGS. 2 and 4, the coating material receiving portion (2100) is formed in a tray shape so as to receive the coating material inside, with the upper surface open, and the surface facing the driving portion (5000) has a coating portion mounting groove (2110) formed so that a skewer described later can be mounted thereon, and the skewer can move back and forth in the coating portion mounting groove (2110).

[0052] The automatic tanghulu manufacturing device according to the present invention may further include a temperature maintaining unit (2500), and the temperature maintaining unit (2500) is coupled to the coating material receiving unit (2100) to maintain the temperature of the coating material, thereby preventing the coating material from burning or hardening.

[0053] At this time, the temperature maintaining part (2500) may be positioned at the bottom of the coating material receiving part (2100) as shown in FIG. 2 to maintain the temperature of the coating material, but depending on the shape of the coating material receiving part (2100) and the capacity of the coating material, it may be positioned on the entire outer side or inside of the coating material receiving part (2100) to maintain the temperature of the coating material.

[0054] The coating material delivery pipe (2200) connects the coating material supply unit (2600), which supplies a coating material to the coating material receiving unit (2100), with the coating material receiving unit (2100), and delivers the coating material from the coating material supply unit (2600) to the coating material receiving unit (2100).

[0055] The above-mentioned transfer shut-off valve (2300) opens and closes the coating material transfer pipe (2200) to turn the coating material transfer pipe (2200) on / off so that an appropriate amount of coating material can be received in the coating material receiving portion (2100).

[0056] At this time, the opening and closing control of the above-mentioned transmission shut-off valve (2300) is performed by the control unit (7000), and the control unit (7000) performs control through sensing by a separately provided capacity verification unit (not shown) of the coating material.

[0057] Here, the capacity verification unit may be configured with a camera that photographs the inside of the coating material receiving unit (2100) to visually verify the capacity of the coating material, or it may be configured with a weight sensor that senses the weight of the coating material receiving unit (2100) to verify the weight of the coating material received, thereby allowing the control of the control unit (7000) to be performed based on this.

[0058] The coating material opening / closing cover (2400) opens and closes the upper surface of the coating material receiving portion (2100) and is coupled to one side of the coating material receiving portion (2100) and is configured as a hinge to rotate and open and close the upper surface of the coating material receiving portion (2100).

[0059] The coating material opening / closing cover (2400) normally keeps the internal space of the coating material receiving portion (2100) closed, and opens it when the skewer moves, thereby minimizing dust from the outside entering the coating material receiving portion (2100).

[0060] Again, referring to FIGS. 1 and 2, the cooling unit (3000) cools the outer surface of the sugar-coated fruit in the coating unit (2000) to harden, and the cooling unit (3000) includes a cooling space unit (3100), a cooling performance unit (3200), and a cooling space opening / closing cover (3300), and is described as follows with reference to FIG. 5.

[0061] The above cooling space (3100) is formed as a tray so as to form a space for accommodating the sugar-coated fruit inside, with the upper surface open, and the surface facing the driving unit (5000) has a cooling unit mounting groove (3110) formed so that a skewer described later can be mounted thereon, allowing the skewer to move back and forth in the cooling unit mounting groove (3110).

[0062] The above cooling performing unit (3200) is coupled to the cooling space unit (3100) to cool the air inside the cooling space unit (3100) for cooling the sugar coating, and, for example, the cooling performing unit (3200) may be composed of a cooling fan.

[0063] That is, the cooling fan is provided on one side of the cooling unit (3200) and supplies cooling air to the internal space, thereby maintaining the internal temperature of the cooling unit (3200) below a certain temperature so that the sugar coating can be cooled to harden.

[0064] Alternatively, the cooling unit (3200) may be composed of Peltier elements, all of which are coupled to the inner surface of the cooling unit (3200), so that the internal temperature of the cooling unit (3200) is maintained below a certain temperature and the sugar coating is cooled to solidify.

[0065] The above cooling space opening / closing cover (3300) opens and closes the upper surface of the cooling space section (3100) and is connected to one side of the cooling space section (3100) and is configured with a hinge to rotate and open and close the upper surface of the cooling space section (3100).

[0066] The cooling space opening / closing cover (3300) normally keeps the internal space of the cooling space (3100) closed, and opens it when the skewer moves, thereby minimizing dust from the outside entering the cooling space (3100).

[0067] The above-mentioned rod portion (4000) is equipped with a skewer for skewering fruit and is configured to fix the fruit by the skewer penetrating it, and the above-mentioned driving portion (5000) is configured to transport the above-mentioned rod portion (4000), which will be explained as follows with reference to FIGS. 6 to 8.

[0068] First, the above-mentioned rod portion (4000) includes a rod portion body (4100) and a skewer fixing body (4200).

[0069] The above-mentioned load body (4100) is coupled with the above-mentioned driving unit (5000) and transported, and a skewer fixing hole (4110) is formed on the inside so that the skewer fixing body (4200) is inserted therein.

[0070] In addition, a y-axis coupling part (4120) is formed on both sides of the above-mentioned rod body (4100) so that a y-axis rotation part (5400) described later can be coupled thereto.

[0071] One side of the above skewer fixing body (4200) is inserted into the skewer fixing body hole (4110), and a skewer coupling hole (4210) is formed in the center of the other side so that the skewer is inserted and coupled.

[0072] Next, the driving unit (5000) transports the load unit (4000), and the driving unit (5000) includes a first transport unit (5100), a second transport unit (5200), an x-axis rotation unit (5300), and a y-axis rotation unit (5400).

[0073] The first transfer unit (5100) is composed of a linear guide and a stepper motor and reciprocates the load unit (4000) in the x-axis direction, which is the same direction as the length direction of the skewer.

[0074] That is, as shown in Fig. 9, the rod portion (4000) equipped with the skewer is moved toward the fruit holder portion (1000), that is, in the x-axis direction which is the same direction as the length direction of the skewer, so that the skewer inserts the fruit inside the fruit holder portion (1000).

[0075] The second transfer unit (5200) is composed of a linear guide and a stepper motor and reciprocates the load unit (4000), specifically the first transfer unit (5100), in the y-axis direction which is perpendicular to the x-axis direction and horizontal to the ground.

[0076] That is, the first transfer unit (5100) is transferred so that the load unit (4000) moves back and forth in the direction of the fruit mounting unit (1000), the coating unit (2000), and the cooling unit (3000).

[0077] The above x-axis rotation part (5300) is positioned inside the load part body (4100) and coupled to the skewer fixing body (4200), and as the skewer fixing body (4200) is rotated about the x-axis, the skewer is rotated about the x-axis.

[0078] Here, it is preferable that the x-axis rotation unit (5300) is driven to apply a sugar coating to the fruit in the coating unit (2000).

[0079] The above y-axis rotation unit (5400) rotates the above load unit (4000) around the y-axis, and as illustrated in FIGS. 8 and 14, when the skewer moves in the order of the fruit holder unit (1000), the coating unit (2000), and the cooling unit (3000), the fruit on the skewer is not separated from the skewer, and at the same time, the skewer is moved along a short path.

[0080] As shown in FIG. 8(b) and FIG. 14, the y-axis rotating part (5400) and the load part (4000) are rotated around the y-axis so that the skewer can be transported without coming into contact with the receiving part mounting groove (1120), the coating part mounting groove (2110), and the cooling part mounting groove (3110).

[0081] It is preferable that the angle (α) at ​​which the y-axis rotation part (5400) rotates the load part (4000) is formed such that the skewer can be removed and separated from the receiving part mounting groove (1120), the coating part mounting groove (2110), and the cooling part mounting groove (3110) with respect to the ground.

[0082] The control unit (7000) controls the fruit mounting unit (1000), the driving unit (5000), the coating unit (2000), and the cooling unit (3000), and specifically includes the driving control unit (7100) and the cover control unit (7200).

[0083] The above drive control unit (7100) controls the first transfer unit (5100), the second transfer unit (5200), the x-axis rotation unit (5300), and the y-axis rotation unit (5400) to be driven according to each stage of tanghulu manufacturing.

[0084] The above cover control unit (7200) controls the operation of the fruit opening / closing cover (1200), the coating material opening / closing cover (2400), and the cooling space opening / closing cover (3300).

[0085] At this time, the drive control unit (7100) and the cover control unit (7200) are organically linked to prevent movement from the cover from being restricted when the skewer is moved.

[0086] The mounting confirmation unit (6000) photographs the fruit mounted on the fruit mounting unit (1000), and the mounting confirmation unit (6000) can be coupled to at least one of the fruit receiving unit (1100) and the fruit opening / closing cover (1200).

[0087] The above mounting verification unit (6000) photographs the fruit contained in each compartment formed in the fruit receiving unit (1100).

[0088] At this time, the control unit (7000) may further include a first transfer control unit (not shown) that controls the first transfer unit (5100) according to the type of fruit confirmed by the mounting confirmation unit (6000).

[0089] That is, the number, location, and type of fruit mounted on the fruit mounting unit (1000) are identified through the shooting of the mounting confirmation unit (6000), and the rod unit (4000) equipped with a skewer controls the movement force and speed for mounting the fruit based on the fruit information for each fruit.

[0090] For example, as shown in FIG. 10 (a), when the same fruit, grape (A), is received one by one in the fruit receiving section (1100) composed of three compartments (1110a, 1110b, 1110c), the first transfer control section can control the speed and movement force when the first transfer control section moves the load section (4000) in the x-axis direction based on the fruit information of the fruit information section, in which the characteristics of the fruit, such as the degree of firmness, thickness of the peel, and hardness of the peel, are stored in the control section (7000).

[0091] At this time, even when the same fruit is contained in three compartments, when the grape (A) contained in the first compartment (1110a) is skewered and the grape (A) contained in the second compartment (1110b) is skewered, the frictional force between the grape (A) contained in the first compartment (1110a) and the skewer also affects the force along with the force of skewering the grape (A) contained in the second compartment (1110b). Therefore, it is desirable to calculate the fruit information and the frictional force to control the speed and movement force when the first transfer control unit moves the load unit (4000) in the x-axis direction.

[0092] Alternatively, as shown in Fig. 10 (b), when different types of fruit, strawberries (B), grapes (A), and tangerines (C) are contained in the fruit receiving section (1100) composed of three compartments (1110a, 1110b, 1110c), the first transfer control section can control the speed and movement force when the first transfer control section moves the load section (4000) in the x-axis direction based on the fruit information of the fruit information section for each fruit.

[0093] By controlling the first transfer control unit, problems such as the fruit not being skewered due to insufficient force or the fruit bursting during the skewering process can be prevented.

[0106] In the first transfer step, the first transfer unit (5100) transfers the load unit (4000) back and forth in the x-axis direction, which is the same direction as the length direction of the skewer, and it is preferable that the first transfer step be performed in the fruit fixing step (S100).

[0107] At this time, in the first transfer step, the control unit (7000) controls the first transfer unit (5100) according to the type of fruit confirmed by the mounting confirmation unit (6000), and since this corresponds to the description of the first transfer control unit, it is omitted.

[0108] In the second transfer step, the second transfer unit (5200) reciprocates the load unit (4000) in the y-axis direction, which is perpendicular to the x-axis direction and horizontal to the ground, and it is preferable that this be performed between the fruit fixing step (S100), the coating step (S200), the cooling step (S300), and the unmounting step (S400).

[0109] In the above x-axis rotation step, the x-axis rotation part (5300) rotates the skewer with respect to the x-axis in the above coating step (S200), and it is preferable that this be performed in the coating step (S200).

[0110] In the above y-axis rotation step, the load part (4000) is rotated with respect to the y-axis, and it is preferable that this be performed between the fruit fixing step (S100), the coating step (S200), and the cooling step (S300).

[0111] In addition, the detailed description of the automatic tanghulu manufacturing method according to the present invention corresponds to the description of the automatic tanghulu manufacturing device according to the present invention described above, so the description is omitted.

[0112] As described above, preferred embodiments of the present invention have been illustrated and described with reference to the drawings; however, the present invention is not limited to the specific embodiments described above.
