Description

Technical Field

[0001] This utility model relates to the field of coating and baking technology for peeled nuts, and specifically to a coating and baking device for peeled nuts. Background Technology

[0002] Most nuts require peeling before being coated with sauce to enhance their flavor. However, traditional nut roasting and coating processes cannot be completed in a single oven. The oven is difficult to clean after coating, making it inefficient for reuse. Furthermore, adding the coating sauce is often done manually, making it difficult to control the amount and proportion of sauce, which can lead to variations in taste and customer complaints.

[0003] Existing nut roasting ovens have limited functionality. When roasting and coating nuts simultaneously, manual feeding is required, which is difficult to control and inefficient. For example, CN21957825U discloses a food coating machine hopper that is easy to clean. This hopper includes a housing, a protective outer shell, and a mounting cavity. The mounting cavity is located inside the protective outer shell. The hopper assembly includes a rotating shaft and a hopper. The rotating shaft is rotatably mounted inside the protective outer shell, and the hopper is fixedly mounted at the end of the rotating shaft. The cleaning unit includes a guide shell, a limiting ring, a limiting bolt, and a moving column. The system comprises a limiting post, a connecting plate, a mounting plate, a mounting post, and a scraper. The guide shell is fixedly installed on the surface of the protective shell, and the limiting ring is fixedly installed inside the guide shell. This application uses a cleaning unit to scrape off the auxiliary materials adhering to the inside of the coating machine cylinder, preventing the auxiliary materials from adhering to the inner wall of the coating machine cylinder and affecting the subsequent coating of food. It also avoids the troublesome manual cleaning of the inner wall of the coating machine cylinder, making the cleaning of the coating machine cylinder more convenient. In contrast, the coating operation in this solution requires manual intervention and the addition of sauces, which can easily cause unevenness and affect the taste.

[0004] Therefore, it is necessary to invent a coating and roasting device for peeled nuts to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a coating and roasting device for peeled nuts, in order to solve the problems of low efficiency and the need for manual intervention in the coating and roasting of nuts in the present invention.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coating and roasting device for peeled nuts includes a rotary roasting oven and a motor. The output shaft of the motor is connected to a rotating heating plate for fixing the rotary roasting oven. The rotating heating plate is powered by an external gas pipeline. A cooling conveyor belt is arranged directly below the rotary roasting oven. A slide rail and a horizontally arranged hydraulic cylinder are installed on the fixed side of the cooling conveyor belt. The slide rail is arc-shaped and has a bracket that can be driven by the hydraulic cylinder to slide along the slide rail. Under the drive of the hydraulic cylinder, the rotary roasting oven can be adjusted from a horizontal to an inclined position. The motor is mounted on the bracket. A feeding chamber is arranged on one side of the cooling conveyor belt. A connecting rod, a movable rod, and a fixed rod are sequentially connected to the bottom of the feeding chamber. The feeding chamber is also connected to a nozzle that can extend into the opening of the rotary roasting oven.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] This invention uses a heating plate installed on the furnace body to ensure that the motor rotates evenly while continuously heating the inside of the furnace. After the baking and coating operations are completed, the hydraulic cylinder and push plate are activated to change the orientation of the originally tilted rotating baking oven. The nuts on the inner wall are evenly rolled and fall onto the cooling conveyor belt, achieving automatic discharge. By installing a feeding hopper on the baking oven, the feeding process is also more time-saving. The position of the nozzle can move up and down under the action of the reciprocating screw, which increases the area of ​​the nozzle spraying into the furnace body and improves the coating efficiency.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figures 1-6 The diagram shows a coating and roasting device for peeled nuts, comprising a roasting rotary oven 1 and a motor 3. The output shaft of the motor 3 is connected to a rotating heating plate 2 for fixing the roasting rotary oven 1. The rotating heating plate 2 is powered by an external gas pipeline. A cooling conveyor belt 4 is arranged directly below the roasting rotary oven 1. A slide rail 6 and a horizontally arranged hydraulic cylinder 5 are installed on the fixed side of the cooling conveyor belt 4. The slide rail 6 is arc-shaped, and a bracket 601 is provided inside the slide rail 6 that can be driven by the hydraulic cylinder 5 to slide along the slide rail 6. Under the drive of the hydraulic cylinder 5, the roasting rotary oven 1 can be adjusted from a horizontal to an inclined position. The motor 3 is mounted on the bracket 601. A feeding chamber 7 is provided on one side of the cooling conveyor belt 4. A connecting rod 9, a movable rod 10, and a fixed rod 11 are connected sequentially to the bottom of the feeding chamber 7. The feeding chamber 7 is also connected to a nozzle 8 that can extend into the opening of the roasting rotary oven 1. When the roasting rotary oven 1 is driven to rotate by the motor 3, the nuts inside the roasting rotary oven 1 are evenly heated and roasted under the action of the rotating heating plate 2, and then the surface of the nuts is continuously coated by the seasonings in the feeding chamber 7.

[0019] The inner wall of the feeding chamber 7 is equipped with a pressure pump 701 that is connected to the nozzle 8 through a pipeline. The pressure pump 701 is electrically connected to an external power source. The feeding chamber 7 is also equipped with an auger plate 702, which is also driven by an external power source.

[0020] The bottom of the auger plate 702 is fixedly connected to a reciprocating screw 703. The reciprocating screw 703 can be controlled to rotate by a servo motor fixed on a bracket on the side of the cooling conveyor belt 4. A movable rod 10 is connected to the S-shaped groove on the reciprocating screw 703 through a connecting rod and ball bearings. The movable rod 10 moves up and down along the fixed rod 11 with only one degree of freedom and its bottom end can retract into the fixed rod 11. The top end of the movable rod 10 is fixedly connected to the connecting rod 9. In this invention, the movable rod 10 is restricted to moving up and down by the fixed rod 11. For example, a limiting groove is provided on the inner wall of the fixed rod 11, and a limiting protrusion that slides up and down in the limiting groove is provided on the outer surface of the movable rod 10.

[0021] There is a large distance between the nozzle 8 and the side wall of the baking rotary oven 1. When the baking rotary oven 1 rotates at a constant speed, the nozzle 8 can continuously spray the seasoning in the feeding chamber 7 into the baking rotary oven 1, coating the surface of the nuts with sauce. The nozzle 8 can also move up and down within the longitudinal range of the baking rotary oven 1 to increase the spraying area.

[0022] The baking rotary oven 1 is polygonal.

[0023] Multiple anti-stick plates 101 are evenly arranged at the bottom of the baking rotary oven 1. The multiple anti-stick plates 101 are arranged in a ring array about the center of the baking rotary oven 1, and the surface of the anti-stick plates 101 is coated with an anti-stick coating.

[0024] A push plate 501 perpendicular to the shaft is mounted on the shaft of the hydraulic cylinder 5. The push plate 501 and the bracket 601 are always in contact. A movable sliding hinge structure can be provided between the push plate 501 and the bracket 601.

[0025] The diameter of the rotating heating plate 2 is greater than the lateral length of the baking rotary oven 1, and the edge of the rotating heating plate 2 is smooth.

[0026] The slider on the support 601 that cooperates with the slide rail 6 has an arc-shaped structure. This design ensures that when the baking rotary oven 1 slides along with the slider, it can also make the same arc-shaped movement as the slide rail 6.

[0027] After the wrapping and baking operations in the baking rotary oven 1 are completed, the hydraulic cylinder 5 and the push plate 501 can be activated to drive the support 601 to slide in the slide rail 6, retracting the originally tilted baking rotary oven 1 to a position similar to parallel to the cooling conveyor belt 4. Ideally, after the final sliding, the baking rotary oven 1 will be at a certain angle to the cooling conveyor belt 4, and the nuts in the baking rotary oven 1 will continuously rotate and roll onto the cooling conveyor belt 4. The cooling conveyor belt 4 will be activated to start conveying to the next production line, and the conveying process will also cool the nuts.

[0028] Working principle of this utility model:

[0029] First, pour the nuts that need to be coated, such as almonds, into the roasting rotary oven 1. The initial state of the roasting rotary oven 1 is at a 30-degree angle with the cooling conveyor belt 4. Then, start the motor 3 to drive the roasting rotary oven 1 to rotate continuously. At the same time, the heating mechanism at the bottom heats the entire roasting rotary oven 1 and the rotating heating plate 2.

[0030] Next, pour the ingredients that need to be coated on the nuts, such as the prepared thick liquid or chocolate sauce, into the feeding chamber 7. The pressure pump 701 is needed to pressurize the ingredients so that they can be smoothly sprayed from the nozzle 8 into the baking rotary oven 1.

[0031] Then, the auger plate 702 in the feeding chamber 7 can evenly convey the sauce or thick liquid to the nozzle 8. The continuous rotation of the auger plate 702 will drive the rotation of the reciprocating screw 703, causing the movable rod 10 to move up and down continuously, which can drive the connecting rod 9 to move up and down, thereby adjusting the position of the nozzle 8 and increasing the area of ​​the seasoning sprayed into the baking rotary oven 1.

[0032] 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.
