Description

Technical Field

[0001] This utility model relates to a blanching machine, specifically a corn blanching machine. Background Technology

[0002] In the corn processing industry, blanching is an essential and crucial step before deep processing of corn. Blanching effectively deactivates the oxidases in corn, preventing browning during subsequent processing and storage. It also has a certain bactericidal effect, improving the quality and shelf life of corn products.

[0003] However, existing corn blanching equipment generally has some problems. Most equipment lacks a disturbance device for the corn, so the corn cannot be turned over during the blanching process and can only be heated on one side or in a localized area. This not only reduces blanching efficiency, but may also damage the corn skin due to prolonged exposure to high-temperature steam, affecting the product's appearance and commercial value. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a corn blanching machine, which effectively solves the problems mentioned in the background art.

[0010] Disruption mechanisms are spaced apart above the conveyor belt along the conveying path. Each disturbance mechanism includes a rotatable shaft and elastic paddles distributed circumferentially along the shaft. The lowest rotation trajectory of the elastic paddles forms a compression gap between the conveyor belt bearing surface and the corn to pass through.

[0015] Preferably, the drive device includes a variable frequency motor and a reduction mechanism connected to the conveyor belt drive.

[0016] Beneficial effects: Optimized blanching effect: The squeezing gap design between the elastic paddle and the conveyor belt causes the corn to be disturbed and tumble as it passes through, allowing it to come into contact with steam at multiple angles.

[0025] The following is in conjunction with the appendix Figures 1-4 The specific embodiments of this utility model will be described in further detail.

[0026] Example 1, by Figures 1-4 This utility model provides a corn blanching machine, including a shell 1, a steam conveying pipe 2, an insulation cover 3, a conveyor belt 4, a drive motor 5, auxiliary components 6, a rotating shaft 7, an elastic plate 8, a guide plate 9, a steam diversion pipe 10, and a steam nozzle 11.

[0027] Casing 1;

[0028] A steam generator is located at the bottom of the casing 1;

[0029] An openable and closable heat-insulating cover 3 is located at the top of the housing 1;

[0030] The circulating conveying mechanism includes a conveyor belt 4 rotatably connected within the housing 1 and a drive device for driving its movement.

[0031] Disruption mechanisms are spaced above the conveyor belt 4 along the conveying path. Each disturbance mechanism includes a rotatable shaft 7 and elastic paddles 8 distributed circumferentially along the shaft. The lowest rotation trajectory of the elastic paddles 8 forms a compression gap between the conveyor belt 4 and the bearing surface for corn to pass through.

[0032] Shell 1: Shell 1 serves as the main frame of the equipment, providing installation support for the internal components and forming a closed blanching space to ensure the stable operation of the blanching process.

[0033] Steam generating device: Located at the bottom of the housing 1, it includes a steam conveying pipe 2 arranged along the length of the housing, a steam distribution pipe 10 connected to the steam conveying pipe 2, and steam nozzles 11 that spray upwards from the steam distribution pipe 10. This device can generate and evenly distribute steam, providing a sufficient heat source for blanching corn, so that the corn is heated evenly during the blanching process.

[0034] Openable and closable heat preservation cover: The heat preservation cover 3 is located at the top of the shell 1. It can be closed when the equipment is running to reduce heat loss and maintain a stable temperature in the blanching space; it can be opened when the equipment is under maintenance or when adding corn for convenient operation.

[0035] The circulating conveying mechanism consists of a conveyor belt 4 rotatably connected within the housing 1 and a drive device that drives its movement. The drive device includes a variable frequency motor 5 and a reduction gear mechanism that is connected to the conveyor belt 4. The variable frequency motor 5 can adjust the running speed of the conveyor belt 4 to adapt to different production needs; the reduction gear mechanism ensures the stable operation of the conveyor belt 4, continuously conveying the corn through the blanching area.

[0036] Disturbing mechanisms: These mechanisms are spaced along the conveyor path above the conveyor belt 4. Each disturbance mechanism includes a rotatable shaft 7 and elastic paddles 8 distributed circumferentially along the shaft. The axial direction of the shaft 7 is perpendicular to the conveying direction. The free end of the elastic paddle 8 extends at an angle of 5-30 degrees to the radial direction of the shaft 7, and the lowest rotation trajectory of the elastic paddle 8 forms a compression gap between it and the bearing surface of the conveyor belt 4, allowing the corn to pass through. During operation, the elastic paddles 8 are squeezed and rotated by the corn, disturbing the corn and causing it to tumble during the blanching process, thus achieving a more thorough blanching effect. The elastic paddles 8 are made of silicone rubber and have hemispherical buffer heads at their ends, ensuring both effective disturbance of the corn and preventing damage.

[0037] Inclined guide plate: An inclined guide plate 9 is provided above the feed end of the housing 1. The lower edge of the guide plate 9 maintains a distance of 50-100mm from the bearing surface of the conveyor belt 4. Its function is to guide the corn smoothly into the conveyor belt 4, avoid corn accumulation or falling, and ensure smooth feeding.

[0038] Working Principle: When this utility model is used, the corn blanching machine works by coordinating the operation of various components to achieve efficient and uniform blanching of corn. First, the corn is guided by the inclined guide plate 9, with its lower edge maintaining a distance of 50-100mm from the bearing surface of the conveyor belt 4. This ensures that the corn can smoothly and orderly enter the conveyor belt 4, avoiding accumulation or falling, thus laying the foundation for the subsequent blanching process.

[0039] Next, the drive motor 5 drives the conveyor belt 4 to start running through the reduction mechanism. Since the drive motor 5 is a variable frequency motor, the running speed of the conveyor belt 4 can be flexibly adjusted according to actual production needs. The corn enters the blanching area inside the shell 1 along with the conveyor belt 4. At this time, the steam generator set at the bottom of the shell 1 starts to work. The steam delivery pipe 2 delivers steam to the steam distribution pipe 10, and the steam nozzles 11 on the steam distribution pipe 10 spray steam upwards, forming a sufficient and uniform steam environment inside the closed shell, providing a heat source for blanching the corn.

[0040] As the corn moves along the conveyor belt 4, it passes through a disturbance mechanism spaced above the conveyor belt 4. The rotating shaft 7 in the disturbance mechanism is axially perpendicular to the conveying direction. The free ends of the elastic paddles 8, distributed circumferentially along the rotating shaft 7, extend at an angle of 5-30 degrees to the radial direction of the rotating shaft 7. A compression gap exists between the lowest rotation trajectory of the elastic paddles 8 and the bearing surface of the conveyor belt 4. When the corn comes into contact with the elastic paddles 8, it compresses the paddles 8, causing them to rotate. This rotation of the elastic paddles 8 then disturbs the corn, causing it to tumble during the blanching process. This tumbling allows all parts of the corn to fully contact the steam, resulting in a more uniform and thorough blanching effect. Simultaneously, the elastic paddles 8 are made of silicone rubber, and their hemispherical buffer heads at the ends effectively prevent damage to the corn during blanching while ensuring the disturbance effect.

[0041] In addition, the closable heat preservation cover 3 is closed when the equipment is running, which can reduce heat loss, maintain a stable temperature in the blanching space, and ensure the steam blanching effect. When the equipment is being repaired or corn is being added, the heat preservation cover 3 can be opened to facilitate related operations by the operators. Throughout the process, the corn is driven by the conveyor belt 4 to complete the feeding, blanching and other processes in sequence, ultimately achieving efficient and stable corn blanching operation.

[0042] Beneficial effects: Optimized blanching effect: The squeezing gap design between the elastic paddle and the conveyor belt causes the corn to be disturbed and tumble as it passes through, allowing it to come into contact with steam at multiple angles. This solves the problem of uneven surface blanching caused by traditional static blanching, and improves the comprehensiveness and thoroughness of blanching.

[0043] Protective design: The elastic paddle is made of silicone rubber and equipped with a hemispherical buffer head, which combines flexible disturbance capability and damage prevention characteristics: the elasticity of silicone rubber can buffer the impact on corn, avoiding squeezing or scratching the corn skin; the hemispherical buffer head further reduces mechanical contact stress, protects the integrity of corn, and is especially suitable for the blanching needs of fresh and tender corn.

[0044] Adaptive adjustment: The free end of the elastic lever forms a 5-30 degree angle with the radial direction of the rotating shaft and can rotate with the corn being squeezed. It can adapt to corn of different sizes, ensuring stable disturbance effect, while avoiding jamming or damage caused by rigid structure.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
