Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fried dough twist production technology, and specifically relates to an oil control device for fried dough twists. Background Technology
[0002] Twisted dough sticks are a traditional Chinese fried snack made by twisting two or three strands of dough together and deep-frying them. Deep-frying equipment is an essential piece of equipment in the production of twisted dough sticks.
[0003] Existing frying equipment for twisted dough sticks simply uses a relatively simple filter to drain excess oil. This method of oil control is not effective, so manual shaking with clamps is required to remove the oil from the twisted dough sticks. Since manual control cannot guarantee the direction and distance of the shaking, it is easy to cause oil to splash, which can cause burns to the skin and waste oil.
[0004] Therefore, there is an urgent need for a device to control the oil content of fried dough twists to solve the above problems. Utility Model Content
[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep-frying twisted dough stick oil control device, comprising a fixing component, an oil control component, and a driving component, including a housing with multiple supports fixedly mounted at its bottom, the housing being used for deep-frying twisted dough sticks; the oil control component including an oil guide box, an oil guide channel, and a filter cover, the oil guide box being positioned directly above the housing, the oil guide channel being fixed to the bottom of the oil guide box and communicating with the inside of the oil guide box, and the output direction of the oil guide channel always facing downwards, the filter cover being rotatably mounted inside the oil guide box; the driving component including a motor cover, a stepper motor, and a rotating shaft, the motor cover being fixed to one side wall of the oil guide box, the stepper motor being fixed inside the motor cover, the rotating shaft being fixed to the output end of the stepper motor, and the rotating shaft rotatably passing through the oil guide box and being fixed to the filter cover.
[0006] As a further improvement of this utility model, one end of the rotating shaft away from the stepper motor passes through the filter cover and is rotatably mounted on the inner wall of the oil guide box.
[0007] As a further improvement of this utility model, both the bottom of the oil guide box and the bottom of the filter cover are configured as semi-circular, and the oil guide box and the filter cover are concentrically arranged.
[0008] As a further improvement of this utility model, a rectangular cover is fixed to the upper end of the oil guide box.
[0009] As a further improvement of this utility model, it also includes a salvage assembly, comprising two support plates symmetrically fixed to the side wall of the housing. Two electro-hydraulic rods are fixed to the two support plates respectively. One of the electro-hydraulic rods has a mounting plate fixed to its output end, and a servo motor is fixed to the mounting plate. The output end of the servo motor is fixed to the oil guide box. The output end of the other electro-hydraulic rod has an L-shaped column fixed to it, and the L-shaped column is rotatably connected to the motor cover.
[0010] As a further improvement of this utility model, the L-shaped column is coaxially arranged with the output end of the servo motor.
[0011] As a further improvement of this utility model, the gap between the filter cover and the oil guide box is 0.3~0.5cm.
[0012] As a further improvement of this utility model, a heating device is provided at the bottom of the chassis.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By using the oil control component and the drive component in synergy, the filter cover will drive the twist to perform centrifugal oil throwing when it swings like a pendulum. The thrown oil will enter the oil guide box and converge, and finally flow into the machine through the fixed oil guide groove. This can prevent oil from splashing during the twist, thus ensuring personal safety on the one hand and saving oil costs on the other.
[0015] 2. By using the retrieval components and drive components in tandem, the oil guide box and filter cover can be flipped, thereby completely retrieval of the twisted dough sticks in the machine box, improving the automated retrieval capability, while ensuring that the frying time of the twisted dough sticks can be kept uniform.

[0021] See Figures 1 to 4 As shown, a deep-frying twisted dough stick oil control device includes a fixing component, an oil control component, and a driving component. The fixing component includes a housing 11, the bottom of which is fixedly mounted with multiple supports. The housing 11 is used for deep-frying twisted dough sticks. The oil control component includes an oil guide box 21, an oil guide channel 22, and a filter cover 23. The oil guide box 21 is located directly above the housing 11. The oil guide channel 22 is fixed to the bottom of the oil guide box 21 and communicates with the inside of the oil guide box 21. The output direction of the oil guide channel 22 is always downward. The filter cover 23 is rotatably mounted inside the oil guide box 21. The driving component includes a motor cover 31, a stepper motor 32, and a rotating shaft 33. The motor cover 31 is fixed to one side wall of the oil guide box 21. The stepper motor 32 is fixed inside the motor cover 31. The rotating shaft 33 is fixed to the output end of the stepper motor 32 and rotates through the oil guide box 21 and is fixed to the filter cover 23.
[0022] It should be noted that the stepper motor 32 in this application is a variable frequency motor, which means it can be driven in both directions.
[0023] Specifically, the stepper motor 32 drives the rotating shaft 33 to drive the filter cover 23 to perform a pendulum motion synchronously with the rotating shaft 33. The twisted coil will roll inside the filter cover 23. During the rotation of the filter cover 23, there are acceleration and deceleration sections. During the acceleration section, the twisted coil inside the filter cover 23 will perform an oil-throwing action through centrifugal force. The oil thrown out from the twisted coil will enter the oil guide box 21 and converge, and finally flow completely into the machine casing 11 through the oil guide groove 22. This can prevent oil from splashing during the oil-throwing process, thus ensuring personal safety on the one hand and saving oil costs on the other.
[0024] In a preferred embodiment, one end of the rotating shaft 33, which is away from the stepper motor 32, passes through the filter cover 23 and is rotatably mounted on the inner wall of the oil guide box 21.
[0025] In other words, the filter cover 23 and the rotating shaft 33 are integrated, and the two ends of the rotating shaft 33 can be limited by the oil guide box 21, thus ensuring that the filter cover 23 can stably perform pendulum motion within the oil guide box 21.
[0026] In a preferred embodiment, the bottom of both the oil guide box 21 and the filter cover 23 are configured as semi-circular, and the oil guide box 21 and the filter cover 23 are concentrically arranged.
[0027] It needs to be explained that, firstly, the twist can roll smoothly on the filter cover 23 with a semi-circular bottom, avoiding collisions and breakage, thus ensuring the integrity of the twist. Secondly, the oil guide box 21 with a semi-circular bottom wall can ensure that the oil thrown out during the pendulum motion of the filter cover 23 can flow completely into the bottom oil guide groove 22, avoiding oil accumulation. Finally, the oil guide box 21 is concentrically set with the filter cover 23 to prevent the oil guide box 21 from interfering with the pendulum motion of the filter cover 23.
[0028] In a preferred embodiment, a rectangular cover 24 is fixed to the upper end of the oil guide box 21.
[0029] It should be explained that during the pendulum motion of the filter cover 23, some of the oil thrown out by the twist will overflow from the top of the oil guide tank 21 due to inertia. The rectangular cover 24 can prevent this phenomenon, thereby ensuring that the thrown-out oil completely converges at the oil guide groove 22, ensuring that the oil is not wasted.
[0030] In a preferred embodiment, the system also includes a salvage assembly comprising two support plates 41 symmetrically fixed to the side wall of the housing 11. Two electro-hydraulic rods 42 are fixed to the two support plates 41 respectively. One of the electro-hydraulic rods 42 has an output end fixed to a mounting plate 43, and a servo motor 44 is fixed to the mounting plate 43. The output end of the servo motor 44 is fixed to the oil guide box 21. The output end of the other electro-hydraulic rod 42 has an L-shaped column 45 fixed to it, and the L-shaped column 45 is rotatably connected to the motor cover 31.
[0031] First, it needs to be explained that the output end of the servo motor 44 can fix one end of the oil guide box 21, while the L-shaped column 45 can limit the other end of the oil guide box 21, thereby ensuring that the oil guide box 21 remains stationary during the oil control process, and thus ensuring that the output end of the oil guide groove 22 always faces downward during the oil control process.
[0032] Secondly, when it is necessary to retrieve the fried dough twists from the casing 11, please refer to [the relevant documentation / reference]. Figure 4 First, start the servo motor 44. The servo motor 44 drives the oil guide box 21 to rotate 180° and then stops the servo motor 44, so that the openings of the oil guide box 21 and the filter cover 23 face downwards. Then, start the two electric hydraulic rods 42 and retract them synchronously. The oil guide box 21 and the filter cover 23 will enter the oil. When all the twists are completely submerged in the opening of the filter cover 23, stop the two electric hydraulic rods 42. Start the servo motor 44 again and drive the oil guide box 21 to rotate 180° and then stop the servo motor 44. Then, start the two electric hydraulic rods 42 and extend them synchronously. When the initial position is reached, stop the two electric hydraulic rods 42. At this time, all the twists in the machine box 11 are completely retrieved and enter the filter cover 23, thus completing the retrieval work.
[0033] In a preferred embodiment, the L-shaped column 45 is coaxially arranged with the output end of the servo motor 44.
[0034] In other words, when the servo motor 44 drives the oil guide box 21 to rotate, the motor cover 31 can rotate around the L-shaped column 45, ensuring that the L-shaped column 45 can have an end limit function on the oil guide box 21.
[0035] In a preferred embodiment, the gap between the filter cover 23 and the oil guide box 21 is 0.3~0.5cm.
[0036] It should be explained that, under normal circumstances, mechanically produced twisted dough sticks include mini twisted dough sticks and standard twisted dough sticks. The diameter of the smaller mini twisted dough sticks is usually 0.5~1cm. The gap between the filter cover 23 and the oil guide box 21 is smaller than the diameter of the mini twisted dough sticks. Therefore, the twisted dough sticks are prevented from entering the gap between the filter cover 23 and the oil guide box 21 during the retrieval process.
[0037] In a preferred embodiment, a heating device is provided at the bottom of the chassis 11 for heating the oil inside the chassis 11.
[0038] Specifically, during the oil control process, the stepper motor 32 drives the rotating shaft 33 to drive the filter cover 23 to perform a pendulum motion synchronously with the rotating shaft 33. The twisted coil will roll inside the filter cover 23. The rotation of the filter cover 23 has an acceleration section and a deceleration section. During the acceleration section, the twisted coil inside the filter cover 23 will perform an oil-throwing action through centrifugal force. The oil thrown out from the twisted coil will enter the oil guide box 21 and converge, and finally flow completely into the machine casing 11 through the oil guide groove 22. Therefore, it can prevent oil from splashing during the oil-throwing process, ensuring personal safety on the one hand and saving oil costs on the other.
[0039] During the process of retrieving the twisted dough sticks, the servo motor 44 is first started. The servo motor 44 drives the oil guide box 21 to rotate 180° and then shuts off the servo motor 44, so that the openings of the oil guide box 21 and the filter cover 23 face downwards. Then, the two electric hydraulic rods 42 are started and retracted synchronously, and the oil guide box 21 and the filter cover 23 will enter the oil. When all the twisted dough sticks are completely submerged in the opening of the filter cover 23, the two electric hydraulic rods 42 are shut off. The servo motor 44 is started again and drives the oil guide box 21 to rotate 180° and then shuts off the servo motor 44. Then, the two electric hydraulic rods 42 are started and extended synchronously. When the initial position is reached, the two electric hydraulic rods 42 are shut off. At this time, all the twisted dough sticks in the machine box 11 are completely retrieved and enter the filter cover 23, thus completing the retrieval work. Then, the oil control work described above is performed on the retrieved twisted dough sticks.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
