Description

Technical Field

[0001] This utility model relates to the field of sunflower seed processing technology, and more specifically, to a roasting machine for sunflower seed processing. Background Technology

[0002] Roasting sunflower seeds is a crucial step in sunflower seed processing. Drum roasters are a common and widely used type of equipment. Existing drum roasters typically consist of a cylindrical drum, a heating device, and a drive mechanism. During operation, the rotation of the drum moves the sunflower seeds, while an external heating device heats and roasts the seeds inside the drum. However, this type of equipment has revealed several shortcomings in practical use.

[0003] Firstly, the roasting effect of sunflower seeds inside the drum is not good. Because the rotation mode of the drum is relatively simple, it is difficult for the sunflower seeds to be fully and evenly turned inside the drum. This easily leads to uneven heating of the sunflower seeds during the roasting process. Some sunflower seeds are burnt on the surface while the inside is not cooked through, which affects the product quality. Secondly, the heating device of the drum roasting machine is usually installed outside the drum, and the heat needs to be conducted to the sunflower seeds through the drum wall, which has low heat transfer efficiency and high energy consumption. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art above, and then to propose a roasting machine for sunflower seed processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A roasting machine for sunflower seeds includes a mounting frame with a circular outer shell. The top of the outer shell has a feeding hopper, and the bottom has a discharge pipe. Inside the outer shell, a circular inner shell is coaxially nested, with its top connected to the feeding end of the feeding hopper. The bottom of the inner shell has an opening aligned with the discharge pipe, and a material-blocking component is installed at the opening. A material-turning component is also rotatably connected inside the inner shell, and a heater is installed inside the material-turning component. The material-turning component is also connected to a drive component.

[0006] Furthermore, the above solution includes two slides located at the opening of the inner shell. A baffle for blocking the opening is slidably fitted between the two slides, and the end of the baffle extends to the outside of the outer shell and is connected to a handle.

[0007] Furthermore, the above solution includes a rotating tube, a heater installed inside the rotating tube, the rotating tube being coaxially rotatably mounted on the inner shell, and several flaps being arranged around the circumference of the rotating tube. Both ends of the rotating tube extend to the outside of the outer shell and are fitted with sealing plates, and one end of the rotating tube is connected to the drive assembly.

[0008] Furthermore, the above solution includes a drive motor mounted on a mounting bracket, and the drive motor is connected to the rotating tube via a drive unit.

[0009] Furthermore, in the above scheme, the driving unit is one of belt drive, chain drive or gear drive.

[0010] Furthermore, the inner shell has a sieve-like structure on its circumferential surface.

[0011] Furthermore, the aforementioned scheme further includes a mesh structure for the flap.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model achieves uniform heating of sunflower seeds by combining the outer shell, inner shell, material turning component and heater to improve roasting quality. The heating method is concentrated and efficient, reducing heat loss for energy saving and environmental protection. A turning component is installed in the inner shell, and a heater is installed inside the turning component. When the drive component drives the turning component to rotate at a constant speed in the inner shell, the turning component continuously turns the sunflower seeds. With the stable heating of the heater, it can ensure that each sunflower seed in the inner shell is heated evenly, effectively avoiding over-roasting or under-roasting of the sunflower seeds, and significantly improving the roasting quality and taste of the sunflower seeds.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: A roasting machine for processing sunflower seeds, see attached document. Figure 1 - Appendix Figure 3 As shown, the device includes a mounting frame 1, on which a circular outer shell 2 is mounted. The top of the outer shell 2 has a feeding hopper 21, providing an inlet for conveying sunflower seeds, and the bottom has a discharge pipe 22, serving as an outlet channel for the sunflower seeds after roasting. Inside the outer shell 2, a circular inner shell 3 is coaxially nested. The top of the inner shell 3 is connected to the discharge end of the feeding hopper 21, creating a falling channel for the sunflower seeds from the feeding hopper 21 to the inner shell 3, ensuring efficient and stable conveying of the sunflower seeds. The bottom of the inner shell 3 has an opening aligned with the discharge pipe 22 (not shown in the figure), and a baffle assembly 4 is installed at the opening. With a controllable opening and closing design, when open, the sunflower seeds in the inner shell 3 can fall freely through the opening and be discharged through the discharge pipe 22. In addition, a turning component 5 is rotatably connected inside the inner shell 3. A heater 6 is installed inside the turning component 5 to provide a heat source for roasting the sunflower seeds. The turning component 5 is also connected to a drive component 7 so that the drive component 7 can drive the turning component 5 to rotate at a uniform speed inside the inner shell 3. During the rotation, the turning component 5 continuously turns the sunflower seeds. With the stable heating of the heater 6, it ensures that each sunflower seed in the inner shell 3 is heated evenly, achieving high-quality roasting processing.

[0015] In the implementation of this utility model, a coaxial nested structure of outer shell 2 and inner shell 3 is adopted. The top feeding hopper 21 is connected to the inner shell 3 through the feeding end. The bottom opening of the inner shell 3 is aligned with the discharge pipe 22 through the controllable material blocking component 4. The material turning component 5 inside the inner shell 3 integrates a heater 6 and is driven to rotate by the drive component 7. During operation, sunflower seeds fall from the feeding hopper 21 into the inner shell 3. The drive component 7 drives the material turning component 5 to rotate and turn the sunflower seeds. The heater 6 provides heat to achieve uniform roasting. After completion, the material blocking component 4 is opened to allow the sunflower seeds to be discharged through the discharge pipe 22.

[0016] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 2 As shown, the baffle assembly 4 includes two slide grooves 41 and is located at the opening of the inner shell 3. A baffle 42 for blocking the opening is slidably fitted between the two slide grooves 41. The end of the baffle 42 extends to the outside of the outer shell 2 and is connected to a handle 43, so that by pulling the handle 43, the baffle 42 can be moved, and the opening of the inner shell 3 can be opened or closed.

[0017] In this design, the material blocking component 4 controls the material through two sliding grooves 41 set at the opening of the inner shell 3 and a sliding baffle 42. One end of the baffle 42 extends to the outside of the outer shell 2 and is connected to a handle 43. When the handle 43 is pulled, the baffle 42 can slide horizontally in the sliding grooves 41. When the baffle 42 blocks the opening of the inner shell 3, the sunflower seeds remain inside the inner shell 3 for roasting. After roasting, the baffle 42 is moved by pulling the handle 43 to slide, so that the opening of the inner shell 3 is exposed. The sunflower seeds can then fall into the discharge pipe 22 through the opening under the action of gravity to complete the discharge. This manual push-pull structure is simple and easy to operate, and it is convenient to flexibly control the sunflower seed discharge process.

[0018] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 2 As shown, the material turning assembly 5 includes a rotating tube 51, a heater 6 installed inside the rotating tube 51, the rotating tube 51 is coaxially rotatably mounted on the inner shell 3, and a number of flaps 52 are arranged around the circumference of the rotating tube 51. Both ends of the rotating tube 51 extend to the outside of the outer shell 2 and are equipped with sealing plates 53. One end of the rotating tube 51 is connected to the drive assembly 7 so that the drive assembly 7 operates to make the rotating tube 51 rotate, and finally the flaps 52 rotate inside the inner shell 3.

[0019] In this design, the turning assembly 5 is centered around the rotating tube 51. When it rotates, the circumferentially distributed flaps 52 on the rotating tube 51 can effectively stir the sunflower seeds. During operation, the drive assembly 7 drives the rotating tube 51 to rotate at a constant speed. The heater 6 inside the rotating tube 51 continuously supplies heat. The flaps 52 continuously turn the sunflower seeds during rotation, so that the sunflower seeds come into contact with the heat source in all directions during rotation, achieving uniform heating and efficient roasting, and ensuring roasting quality.

[0020] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the drive assembly 7 includes a drive motor 71, which is mounted on the mounting bracket 1. The drive motor 71 is connected to the rotating tube 51 through a drive unit 72, so that the drive motor 71 drives the rotating tube 51 to rotate through the drive unit 72. The drive unit 72 is one of the belt drive, chain drive or gear drive in the prior art.

[0021] In this design, the drive assembly 7 uses a drive motor 71 mounted on the mounting frame 1 as its power source. It is connected to one end of the rotating tube 51 via a drive unit 72. When the drive motor 71 is powered on, the power is transmitted to the rotating tube 51 via the drive unit 72, causing the rotating tube 51 to rotate coaxially. This causes the flaps 52, which are circumferentially distributed on the rotating tube 51, to rotate and continuously turn the sunflower seeds in the inner shell 3. This, in conjunction with the heater 6 inside the rotating tube 51, enables the sunflower seeds to be roasted evenly.

[0022] In the above solution, considering that impurities may be present during the roasting process of sunflower seeds, in order to facilitate the separation and processing of these impurities, the following method is provided (see Appendix). Figure 4 As shown, the inner shell has a sieve structure on its three circumferential surfaces.

[0023] In this design, the drive motor 71 drives the rotating tube 51 and the flip plate 52 to rotate via the drive unit 72. The heater 6 inside the rotating tube 51 provides heat, and the flip plate 52 flips the sunflower seeds for even roasting. During this process, small impurities such as debris and dust generated by friction between the sunflower seeds will fall off naturally through the mesh of the screen structure on the circumferential surface of the inner shell 3 during the flipping process, preventing impurities from mixing with the sunflower seeds. The separated impurities are directly discharged through the discharge pipe 22. After roasting is completed, the baffle assembly 4 is opened, and the clean sunflower seeds are discharged through the bottom opening of the inner shell 3 and the discharge pipe 22, effectively improving the quality of the finished sunflower seeds.

[0024] Regarding the above solution, considering the effectiveness of the flip-board 52, therefore, refer to the appendix. Figure 5 As shown, the flap 52 has a mesh structure.

[0025] In this design, during operation, the drive motor 71 drives the rotating tube 51 and the mesh structure flap 52 to rotate via the drive unit 72. The heater 6 inside the rotating tube 51 continuously supplies heat. During the process of turning the sunflower seeds, the mesh structure flap 52 can reduce the squeezing damage to the sunflower seeds due to its hollow characteristics, while ensuring that the hot air can fully penetrate and the sunflower seeds are heated evenly from all directions. At the same time, the sunflower seeds can flow and disperse more smoothly under the stirring of the mesh flap 52, and small impurities can also fall off in time through the mesh. Combined with the screen structure on the circumferential surface of the inner shell 3, the impurity separation efficiency is further improved.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
