Description

Technical Field

[0001] This utility model relates to the field of nut production technology, specifically to a nut stir-frying device. Background Technology

[0002] Roasting nuts is a processing method that uses heat conduction to evaporate internal moisture, convert oils, and produce unique flavors. The performance of the roasting equipment directly affects the color, crispness, and flavor release of the nuts. The shortcomings of existing equipment in terms of heat uniformity and process control precision hinder the standardized production of high-quality nut products.

[0003] In existing technologies, conventional stir-frying devices generally adopt a drum structure, combined with spiral blades to drive the stir-frying process of nuts. This design uses the rotation of the drum and the synergistic effect of the spiral blades to make the nuts tumble continuously inside the drum, thereby achieving a uniform stir-frying effect. However, because the spiral blades have a clear guiding function, the nuts tend to remain and concentrate in the innermost area of ​​the drum when they tumble inside. This phenomenon directly leads to a lack of effective contact between the nuts and other spaces inside the drum, making it impossible for the heat source to fully act on all the nuts during the heat transfer process, thus resulting in a reduction and waste of heat source utilization efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a nut-stirring device for nut production, in order to solve the problem mentioned in the background art that the nuts are always on the innermost side of the drum and cannot fully contact the heating position of the drum.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nut-making and roasting device, comprising a heating cylinder and a drum rotatably connected to the heating cylinder, a rotating disk rotatably connected to the drum, a first spiral blade rotatably connected to the rotating disk, a second spiral blade rotatably connected to the rotating disk, a drive assembly mounted on the heating cylinder, a support assembly mounted on the heating cylinder, and a lifting assembly mounted on the support assembly. The drive assembly drives the drum to rotate inside the heating cylinder, and the lifting assembly drives the heating cylinder to tilt and pour out the nuts inside the drum through the support assembly.

[0006] In the preferred embodiment of this technical solution, the roller has a limiting groove at the corresponding position of the rotating disk, and the rotating disk rotates inside the limiting groove.

[0007] In the preferred embodiment of this technical solution, there are two of each of the first and second helical blades, and the first and second helical blades rotate in opposite directions. The two first and second helical blades are symmetrically arranged on the rotating disk.

[0008] According to the preferred embodiment of this technical solution, the drive assembly includes a motor mounted on the heating cylinder, a first gear fixedly connected to the output end of the motor, a second gear meshing with the first gear, a third gear fixedly connected to the second gear, a fourth gear meshing with the third gear, and a fifth gear meshing with the fourth gear. The fifth gear is fixedly connected to the heating cylinder, and the second and third gears are fixedly connected to the drum.

[0009] In the preferred embodiment of this technical solution, four fourth gears are provided, and the four fourth gears are respectively installed on the two first helical blades and the two second helical blades.

[0010] According to the preferred embodiment of this technical solution, the support assembly includes a first mounting plate mounted on the heating cylinder, a first hinge seat rotatably connected to the first mounting plate, a support frame fixedly connected to the first hinge seat, a second mounting plate mounted on the heating cylinder, and a second hinge seat rotatably connected to the second mounting plate.

[0011] According to the preferred embodiment of this technical solution, the lifting assembly includes a third hinge seat mounted on a support frame, a rotating block rotatably connected to the third hinge seat, and an electric telescopic rod fixedly connected to the rotating block, with the second hinge seat mounted on the output end of the electric telescopic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The combined motion of the drum's revolution and the internal spiral blades' rotation creates strong three-dimensional turbulence, which makes the nuts evenly distributed and tumble within the entire annular space of the drum. This completely solves the problem of uneven heating caused by nuts being concentrated on the inner side in traditional equipment. This allows heat energy to be efficiently and evenly transferred to each nut, resulting in a product with highly consistent color and crispness, and excellent quality.

[0013] 2. The entire frying process is driven by a single motor, with a compact structure and simple control. After frying, the material is discharged automatically by an electric telescopic rod, realizing full mechanization from feeding, frying to discharging. This greatly reduces the labor intensity of operators and completely avoids the risks of manual discharging in high-temperature environments, thus improving production safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a nut production and nut roasting device, including a heating cylinder 21 and a drum 22 rotatably connected to the heating cylinder 21, a rotating disk 23 rotatably connected to the drum 22, a first spiral blade 24 rotatably connected to the rotating disk 23, a second spiral blade 25 rotatably connected to the rotating disk 23, a drive assembly mounted on the heating cylinder 21, a support assembly mounted on the heating cylinder 21, and a lifting assembly mounted on the support assembly. The drive assembly drives the drum 22 to rotate inside the heating cylinder 21, and the lifting assembly drives the heating cylinder 21 to tilt and pour out the nuts inside the drum 22 through the support assembly. By setting the independently rotatable first spiral blade 24 and second spiral blade 25 inside the drum 22, the blades rotate in the opposite direction while the drum 22 revolves, forming a complex turbulence, which completely breaks the concentrated distribution of nuts inside the drum 22, allowing them to fully diffuse across the entire cross-section of the drum 22 and make uniform contact with the hot wall, greatly improving the heat conduction efficiency and roasting uniformity.

[0018] Please see Figure 4 A further solution based on this embodiment is as follows: the roller 22 has a limiting groove at the corresponding position of the rotating disk 23, and the rotating disk 23 is usually provided with a bearing structure inside the limiting groove, which provides stable and low-friction rotational support for the rotating disk 23, ensuring that it can rotate smoothly under the drive of the roller 22. At the same time, it provides a reliable installation base for the independent rotation of the internal spiral blades, and can close its position to prevent the nuts from falling into the gear engagement position and affecting the work.

[0019] Please see Figure 2 - Figure 4 A further solution based on this embodiment is as follows: two first spiral blades 24 and two second spiral blades 25 are provided, and the first spiral blades 24 and the second spiral blades 25 rotate in opposite directions. The two first spiral blades 24 and the two second spiral blades 25 are symmetrically arranged on the rotating disk 23. The symmetrical arrangement and opposite rotation of the first spiral blades 24 and the second spiral blades 25 are the key to generating efficient turbulence. When they rotate, one set of blades pushes the material in one direction, while the other set pushes it in the opposite direction. This action impacts and cancels each other in the central area of ​​the drum 22, thereby powerfully throwing and spreading the nuts from the central area to the entire annular space around the drum 22, achieving a three-dimensional stir-frying effect.

[0020] Please see Figure 1 - Figure 3 A further embodiment of this solution is as follows: the drive assembly includes a motor 31 mounted on the heating cylinder 21, a first gear 32 fixedly connected to the output end of the motor 31, a second gear 33 meshing with the first gear 32, a third gear 34 fixedly connected to the second gear 33, a fourth gear 35 meshing with the third gear 34, and a fifth gear 36 meshing with the fourth gear 35. The fifth gear 36 is fixedly connected to the heating cylinder 21, and the second gear 33 and the third gear 34 are fixedly connected to the drum 22. The drive assembly causes the first spiral blade 24 and the second spiral blade 25 to revolve and rotate. The motor 31 drives the first gear 32, which in turn drives the second gear 33 and the third gear 34 to rotate, thereby driving the drum 22 to revolve. Meanwhile, the fixed fifth gear 36 meshes with the fourth gear 35 mounted on the blade shaft. When the drum 22 revolves, the fourth gear 35 moves around the fifth gear 36. Since the fifth gear 36 is fixed, the fourth gear 35 is forced to rotate, thereby driving the first spiral blade 24 and the second spiral blade 25 to rotate. This design can achieve complex compound motion with only one motor 31.

[0021] Please see Figure 3 A further solution based on this embodiment is as follows: four fourth gears 35 are provided, and the four fourth gears 35 are respectively installed on the two first spiral blades 24 and the second spiral blades 25. The four fourth gears 35 ensure that each first spiral blade 24 and the second spiral blade 25 can obtain independent and synchronous drive. They are all meshed with the fixed fifth gear 36, ensuring that the rotation speed of all blades and the revolution speed of the drum 22 maintain a strict proportional relationship, thereby forming a stable and controllable stir-frying flow field.

[0022] Please see Figure 5A further embodiment of this solution is as follows: the support assembly includes a first mounting plate 41 mounted on the heating cylinder 21, a first hinge seat 42 rotatably connected to the first mounting plate 41, a support frame 43 fixedly connected to the first hinge seat 42, a second mounting plate 44 mounted on the heating cylinder 21, and a second hinge seat 45 rotatably connected to the second mounting plate 44. The first hinge seat 42 and the second hinge seat 45 provide two reliable rotation fulcrums for the tilting movement of the heating cylinder 21, ensuring the smoothness and accuracy of the tilting action, while ensuring the overall stability of the device in the frying working state.

[0023] Please see Figure 5 A further solution based on this embodiment is as follows: The lifting assembly includes a third hinge seat 51 mounted on the support frame 43, a rotating block 52 rotatably connected to the third hinge seat 51, and an electric telescopic rod 53 fixedly connected to the rotating block 52. The second hinge seat 45 is mounted on the output end of the electric telescopic rod 53. When the electric telescopic rod 53 extends or retracts, its output end pushes the second hinge seat 45 connected to the heating cylinder 21, forcing the heating cylinder 21 and the roller 22 to rotate as a whole around the axis of the first hinge seat 42, thereby achieving a controllable tilt angle, so that the roasted nuts can be poured out smoothly, eliminating the heavy and dangerous manual discharge operation.

[0024] Working principle: Nuts are poured into the left end opening of the drum 22. The starting motor 31 drives the drum 22 to revolve around its central axis via the first gear 32, second gear 33, and third gear 34 of the drive assembly. At the same time, since the fourth gear 35, which is fixedly mounted on the spiral blade shaft, meshes with the fifth gear 36, which is fixed to the heating cylinder 21, the fourth gear 35 is forced to move around the fifth gear 36 when the drum 22 revolves, thus rotating on its own axis. This drives the first spiral blade 24 and the second spiral blade 25 to rotate in the opposite direction to or in a different direction from the drum 22's revolution. Rotating at a constant speed, the nuts inside the drum 22 are violently thrown up, broken up, and mixed intensely along the entire annular cross-section of the drum 22 under the combined action of gravity, centrifugal force, and the first spiral blade 24 and the second spiral blade 25 rotating in opposite directions. This allows for full and uniform heat exchange with the uniformly heated inner wall of the drum 22. After roasting, the motor 31 stops, the electric telescopic rod 53 of the lifting assembly extends, and lifts one end of the heating cylinder 21, causing it to tilt around the first hinge seat 42. The roasted nuts then automatically slide out from the opening end of the drum 22 under the action of gravity, completing the discharge.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
