[0032] Embodiment 1:

[0033] The present utility model provides a powder coating device for fried potatoes.

[0034] In an embodiment of the present utility model, a powder coating device for fried potatoes includes a frame 1. A feeding mechanism is provided on the frame 1. It further includes a conveying mechanism 2, a filtering mechanism 3, a separating mechanism 4, and a screening mechanism 5. The conveying mechanism 2 is arranged on the top of the frame 1 and is used for conveying potato pieces. The feeding mechanism is used for feeding powder to the conveying mechanism 2. The separating mechanism 4 is arranged above the conveying mechanism 2 to separately coat the potato pieces and the powder. The filtering mechanism 3 is located below the conveying mechanism 2 and is used for filtering the powder. The screening mechanism 5 is arranged at the bottom of the frame 1 and is connected to the feeding mechanism, and the screening mechanism 5 is used for receiving and screening the powder.

[0035] Specifically, as Figures 1 to 5As shown, in a flour coating device for fried potatoes of the present utility model, the frame 1 serves as the basic support structure of the entire device, which can bear the weights of the feeding mechanism, the conveying mechanism 2, the filtering mechanism 3, the separating mechanism 4, and the screening mechanism 5, so as to prevent the present utility model from shaking or toppling during operation. Further, since the conveying mechanism 2 is provided on the frame 1, the conveying mechanism 2 can be a belt conveyor, thereby enabling the smooth and continuous conveyance of potato pieces through the conveying mechanism 2. During the conveyance of the potato pieces, the feeding mechanism can transfer the powder material onto the conveying mechanism 2, thereby achieving the flour coating of the potato pieces, and the structural design is simple and reasonable.

[0036] It can be understood that since the separating mechanism 4 is arranged above the conveying mechanism 2, the separating mechanism 4 can be made into a rake structure. When the conveying mechanism 2 conveys the potato pieces, at this time, the powder material falls onto the conveying mechanism 2 under the action of the feeding mechanism and directly covers the surface of the potato pieces, thus completing the partial surface flour coating of the potato pieces; as the conveying mechanism 2 continues to operate, when the potato pieces pass through the separating mechanism 4, the separating mechanism 4 abuts against the potato pieces and can turn over the potato pieces, and during this process, the powder material is continuously fed by the feeding mechanism, and thus the other surfaces of the potato pieces can be coated with powder, improving the integrity of the surface flour coating of the potato pieces; at the same time, several nail teeth on the separating mechanism 4 can separate the powder material on the conveying mechanism 2, that is, the powder material is blocked by the nail teeth when passing through the separating mechanism 4 and is separated into several powder material bands, and the potato pieces are distributed on several powder material bands after passing through the separating mechanism 4. Obviously, the powder material will turn inward and accumulate when passing through two adjacent nail teeth to form a powder material band, and since the potato pieces can only pass through between two nail teeth, the two sides of the potato pieces can be powdered, thereby further improving the integrity of the flour coating of the potato pieces and ensuring the flour coating effect of the potato pieces. In addition, when different potato pieces are adhered to each other, since the distance between two nail teeth only allows the potato pieces of corresponding size to pass through, the separating mechanism 4 can separate the adhered potato pieces, thereby effectively avoiding the situation that the local surface of different potato pieces is not coated with powder due to mutual adhesion, ensuring the integrity of the flour coating of the potato pieces, and the use is reliable.

[0037] It should be noted that when the powder material and the floured potato pieces fall from the conveying mechanism 2, since the filtering mechanism 3 is located below the conveying mechanism 2, the filtering mechanism 3 can pick up the powder material and the floured potato pieces at this time. The filtering mechanism 3 can be a conveyor with a mesh conveyor belt in the prior art, which can not only convey the floured potato pieces to the next process, but also enable the powder material to directly fall from the filtering mechanism 3 and enter the screening mechanism 5, thereby realizing the filtering separation of the powder material and the potato pieces. The structural design layout is reasonable, ensuring the continuous operation of the potato deep processing production line and improving the production efficiency. In addition, it can be understood that due to the height difference between the filtering mechanism 3 and the conveying mechanism 2, when the floured potato pieces fall onto the filtering mechanism 3, the powder material that is not firmly attached to the surface of the potato pieces will automatically fall off, thereby being able to remove the excess and loosely attached powder material on the surface of the potato pieces, ensuring uniform flour coating on the surface of the potato pieces, effectively avoiding the influence on the frying effect and edible taste due to too thick powder material, ensuring the appearance of the finished product, and avoiding the generation of burnt and charred pieces, providing favorable conditions for the frying process.

[0038] It should be noted that since the surface of the potato pieces is in a wet state when the potato pieces are conveyed onto the conveying mechanism 2, some of the powder material will encounter water and agglomerate to form wet powder material lumps, and it is difficult to perform flour coating operations on the potato pieces with the wet powder material lumps. In order to ensure the flour coating effect on the potato pieces, it is necessary to screen and separate the wet powder material lumps. In a flour coating device for fried potatoes of the present invention, since the screening mechanism 5 is arranged at the bottom of the frame 1, the powder material falling from the conveying mechanism 2 and the filtering mechanism 3 can be picked up by the screening mechanism 5, and the dry powder material and the wet powder material lumps can be screened at the same time. Moreover, the screening mechanism 5 is connected to the feeding mechanism, so that the screened dry powder material can enter the feeding mechanism and be conveyed to the conveying mechanism 2 again by the feeding mechanism, thereby completing the recycling of the dry powder material, saving the production cost and being reliable in use.

[0039] In summary, it is obvious that the present invention expands the usage functions through the filtering mechanism 3, the separation mechanism 4 and the screening mechanism 5, that is, removing excess powder material, separating dry and wet powder materials and recycling the powder material. The overall structural design layout is simple and reasonable, with characteristics such as high automation degree and high flour coating efficiency, meeting the requirements of modern food processing production lines and having strong practicability.

[0040] In addition, the feeding mechanism in the present utility model can adopt a screw conveyor (auger) in the prior art. Using a screw conveyor to convey powder is a well-known and common conventional means in a breading machine. For example, the powder feeding auger proposed in the patent with the publication number CN209898257U. Therefore, the feeding mechanism will not be elaborated here, and the specific composition structure is not shown in the attached drawings of the specification. In addition, a control system is also provided on the frame 1 of the present utility model. The control system and the communication connection mode between it and each mechanism are all mature prior arts and will not be elaborated here. The purpose of the present utility model is to solve the problems that the existing breading machine cannot effectively separate the adhered potato pieces, it is difficult to ensure the integrity of the breading of potato pieces, the breading effect on potato pieces is reduced, and the function is single.

[0041] In one embodiment, the separation mechanism 4 includes a housing 6 and a separation component 7. The housing 6 is detachably installed above the conveying mechanism 2. An inlet 8 for communicating with the feeding mechanism is provided on the housing 6. A plurality of conveying channels 9 are formed in the housing 6 by a plurality of inclined plates arranged at intervals. The separation component 7 is arranged at the outlet of the conveying channel 9 and is used to separate potato pieces and powder. Specifically, as Figure 1 、 Figure 2 and Figure 4 shown, the housing 6 can shield the conveying mechanism 2, thereby reducing the attachment of external dust and impurities to the potato pieces together with the powder and ensuring the production quality of the finished product. At the same time, since a plurality of conveying channels 9 are formed in the housing 6 by a plurality of inclined plates arranged at intervals, in the actual production of the present utility model, the separation structure can be arranged between two adjacent conveying channels 9. Thus, when the powder covers the potato pieces through one conveying channel 9, at this time, the separation mechanism 4 can turn the potato pieces, and the powder can simultaneously fall from another conveying channel 9 and cover the potato pieces, thereby ensuring the integrity of the breading of potato pieces and being reliable in use.

[0042] In one embodiment, the separation component 7 includes a mounting rod 10 and a plurality of separation blocks 11. The two ends of the mounting rod 10 are detachably connected to the housing 6 respectively. A plurality of separation blocks 11 are detachably installed on the mounting rod 10 and are uniformly and spaced along the extension direction of the mounting rod 10, and a plurality of separation blocks 11 are arranged in a gradually expanding manner along the conveying direction of the conveying mechanism 2. Specifically, as Figures 1 to 5As shown, the mounting rod 10 and the housing 6 can be detachably connected by a threaded connection, and the plurality of partition blocks 11 can also be detachably connected to the mounting rod 10 by a threaded connection, thereby facilitating the disassembly, assembly, and replacement of the mounting rod 10 and the plurality of partition blocks 11. Furthermore, because the plurality of partition blocks 11 are evenly and spaced apart along the extending direction of the mounting rod 10, and are gradually arranged in a diverging manner along the conveying direction of the conveying mechanism 2, they not only fully and evenly cover the powder and potato chunks on the conveying mechanism 2, ensuring the powder and potato chunks are turned and coated with powder, but also facilitate the gradual separation of stuck potato chunks during the conveying process, effectively preventing the potato chunks and powder from accumulating at the plurality of partition blocks 11.

[0043] In one embodiment, the conveying mechanism 2 includes a first drive assembly and a first conveyor belt 12. The first drive assembly is used to drive the first conveyor belt 12 to rotate in a circular manner. Annular baffles 13 are formed on both sides of the first conveyor belt 12. The first conveyor belt 12 is used to support potato chunks and powder. A protective cover 14 for blocking potato chunks and powder is detachably mounted on the frame 1. The protective cover 14 is located above the first conveyor belt 12 and is arranged close to the filtering mechanism 3.

[0044] Specifically, if Figures 1 to 4 As shown, annular baffles 13 are formed on either side of the first conveyor belt 12 in the conveying mechanism 2 to prevent the powder and potato chunks from falling off or overflowing from the first conveyor belt 12, ensuring efficient conveying of the powder and potato chunks and providing stable conditions and guarantees for the coating of the potato chunks. Furthermore, a protective cover 14 is positioned above the first conveyor belt 12 and near the filter mechanism 3. This prevents the powder and potato chunks from splashing freely due to inertia during conveyance, allowing them to fall onto the filter mechanism 3 along a predetermined path. Furthermore, the protective cover 14 is detachably attached to the frame 1 using a threaded connection, making it easy to disassemble and clean the protective cover 14. It is worth noting that the first drive assembly, which drives the first conveyor belt 12 in a circular motion, includes a motor, a reducer, rollers, and other components. The speed and direction of the first conveyor belt 12 can be adjusted by precisely controlling the motor's speed and direction of rotation. This is a mature prior art and will not be elaborated upon here.

[0045] In one embodiment, the filtering mechanism 3 includes a second driving assembly and a second conveyor belt 15, the second driving assembly is used to drive the second conveyor belt 15 to rotate cyclically, the second driving assembly is connected to the first driving assembly, and the second conveyor belt 15 is a hollow fence structure. Specifically, Figure 1 、 Figure 3 and Figure 4As shown, by making the second conveyor belt 15 into a hollow fence structure, the excess powder can be discharged through the gaps in the second conveyor belt 15, while the potato pieces, due to their large size, remain on the conveyor belt and are transported to the next process, thereby achieving the effect of separating the potato pieces from the excess powder. It is worth noting that the second drive assembly is the power source of the filtering mechanism 3 and is responsible for driving the second conveyor belt 15 to rotate in a circular manner. It also includes a motor, a reducer, rollers, etc. The structure of the second drive assembly is a mature existing technology and will not be described in detail here. However, since the second drive assembly is connected to the first drive assembly in a transmission connection method that can adopt a chain drive, the operating speed and direction of the two can be kept synchronized or proportionally coordinated to ensure the continuity and efficiency of the potato flour coating process.

[0046] In one embodiment, a powder removal rod 16 is detachably mounted on the frame 1, with slopes formed on both sides of the powder removal rod 16. The powder removal rod 16 is located above the second conveyor belt 15 and is used to turn over the potato pieces. Specifically, Figure 1 and Figure 4 As shown, the de-powdering rod 16 is detachably mounted on the frame 1 through a threaded connection, making it easy to disassemble, clean, and replace the de-powdering rod 16. Furthermore, because the de-powdering rod 16 is located above the second conveyor belt 15, when the potato pieces move on the second conveyor belt 15 until they come into contact with the de-powdering rod 16, the potato pieces can flip over the de-powdering rod 16, thereby further removing excess powder and making the powder adhered to the surface of the potato pieces more uniform. Furthermore, because the de-powdering rod 16 has slopes formed on both sides, it can improve the smoothness of the potato pieces flipping over the de-powdering rod 16, preventing the potato pieces from stagnating and accumulating due to the obstruction of the de-powdering rod 16.

[0047] In one embodiment, the screening mechanism 5 includes a collecting trough 17 and a third driving assembly for driving the collecting trough 17. The collecting trough 17 is used to receive the powder falling from the conveying mechanism 2 and the filtering mechanism 3. A screen 18 is provided in the collecting trough 17, and a powder outlet pipe 19 connected to the feeding mechanism is formed at the bottom of the collecting trough 17. Specifically, Figure 1 、 Figure 3 and Figure 4As shown, the collecting trough 17 can collect the powder materials that fall from the conveying mechanism 2 and the filtering mechanism 3, preventing the powder materials from scattering onto the ground from the first conveyor belt 12 or the second conveyor belt 15, which facilitates the subsequent screening and recycling of the powder materials. Further, since a screen 18 is provided inside the collecting trough 17, impurities, large particles or wet powder material lumps can be effectively separated out, while the dry powder material passes through the screen 18 and enters the feeding mechanism through the powder outlet pipe 19, thereby realizing the recycling of the dry powder material and improving the utilization rate of the powder material. It should be noted that the third driving component, as the power source of the screening mechanism 5, belongs to mature prior art. The third driving component includes a vibration source, an elastic member, etc., which can drive the collecting trough 17 to vibrate through the power source to ensure the screening effect of the screen 18 on the powder material.

[0048] In an embodiment, a discharge pipe 20 is further formed at the bottom of the collecting trough 17. The discharge pipe 20 and the powder outlet pipe 19 are arranged at intervals. The screen 18 extends to the discharge pipe 20 and blocks the powder outlet pipe 19, and the screen 18 is inclined along the extending direction of the collecting trough 17. Specifically, as Figure 4 shown, by arranging the discharge pipe 20 and the powder outlet pipe 19 at intervals, the dry powder material and the wet powder material lumps can be prevented from being remixed. Further, since the screen 18 extends to the discharge pipe 20 and blocks the powder outlet pipe 19, and the screen 18 is inclined along the extending direction of the collecting trough 17, the impurities, large particles or wet powder material lumps on the screen 18 can be discharged from the discharge pipe 20, and the structural design is simple and reasonable.

[0049] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
