Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and relates to a device for removing excess flour from the surface of broad beans. Background Technology

[0002] In the food processing of broad beans, in order to improve the taste and appearance after frying, it is usually necessary to coat the broad beans with flour. The coating process usually involves pouring a large amount of flour directly into a mixing tank and using a stirring device to coat the wet broad beans with flour. However, this traditional coating method has obvious defects: due to uneven stirring and insufficient precision in controlling the ratio of flour to broad beans, it is very easy for some broad beans to have too much flour adhering to their surface, forming a thick layer of flour.

[0003] These broad beans with excessive flour coating will cause a series of problems in the subsequent frying process. On the one hand, the excess flour is prone to burning during high-temperature frying, affecting the color and taste of the product, and even producing harmful substances. On the other hand, too much flour will cause the broad beans to stick together and form clumps, which not only reduces the appearance of the product, but also causes uneven heating during the frying process, further affecting the product quality. In addition, the excess flour will form waste residue after frying, increasing the workload of subsequent equipment cleaning, while also wasting flour resources and increasing production costs.

[0004] Currently, the industry lacks specialized equipment for removing excess flour from the surface of broad beans. Some manufacturers use manual sifting, which is inefficient, labor-intensive, and produces inconsistent flour removal results, failing to meet the needs of large-scale production. Other companies have attempted to use ordinary vibrating screens for flour removal, but the design of these screens is not optimized for the physical characteristics of broad beans, resulting in incomplete flour removal, easy breakage of broad beans, and low flour recovery rates. Therefore, this technical solution was developed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a device for removing excess flour from the surface of broad beans, thereby solving the aforementioned technical problems.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A device for removing excess flour from broad beans includes a support frame with an inclined screening structure movably connected to it. A drive mechanism is mounted on the support frame and is connected to the screening structure to drive it to vibrate. A flour collection component is located below the screening structure on the support frame to collect flour that falls off the screening structure. A material collection component is located below the output end of the screening structure on the support frame to collect the broad beans after flour removal. Anti-detachment components are located on both sides of the screening structure to prevent the broad beans from detaching from the screening structure. A control component is mounted on the support frame and is electrically connected to the drive mechanism to control its operation.

[0008] The working principle of this utility model is as follows: excess flour is removed based on vibration screening technology; when the equipment is started, the operator starts the drive mechanism through the control button of the control component, and the drive motor of the drive mechanism transmits power to the drive shaft through the transmission component, causing the drive shaft to rotate; the drive shaft drives the screening structure to generate continuous vibration through the eccentric connecting rod assembly.

[0009] The broad beans to be de-floured are conveyed to the high end of the screening structure and slide down the screening structure under the combined action of their own gravity and the vibration of the screening structure. During the sliding process, the excess flour attached to the surface of the broad beans is separated by the vibration and falls into the flour collection component below through the sieve holes of the screening structure. The inclined collection trough of the flour collection component causes the flour to converge at the low end and enter the collection bag through the discharge hopper to complete the recycling.

[0010] After removing excess flour, the broad beans continue to slide, exiting from the lower end of the screening structure and entering the material collection component for collection. The anti-detachment component effectively prevents the broad beans from detaching from the screening structure during vibration and sliding, ensuring the stability of flour removal. Operators can change the speed of the drive motor and adjust the vibration frequency of the screening structure by controlling the speed adjustment knob of the component to adapt to the flour removal needs of different broad beans.

[0011] Furthermore, the drive mechanism is defined as including a drive motor, a transmission shaft, a transmission assembly, and an eccentric connecting rod assembly. The transmission assembly is further defined as a combination of a drive pulley groove, a driven pulley groove, and an annular belt. This definition makes the structure of the drive mechanism clearer. Power transmission is achieved through belt drive, which has the characteristics of smooth transmission, low noise, and low cost. At the same time, the setting of at least two annular belts can improve the reliability of transmission and avoid equipment downtime due to the breakage of a single belt.

[0012] Furthermore, it is defined as a combination of an eccentric wheel, a connecting rod, and a linkage structure. The eccentric wheel is fixed on the drive shaft, and the rotational motion of the drive shaft is converted into the reciprocating motion of the connecting rod by setting the eccentricity, which in turn drives the linkage structure to vibrate the screening structure. The rotational connection between the connecting rod and the eccentric wheel and linkage structure ensures the flexibility of motion transmission, reduces mechanical wear, makes the vibration of the screening structure more stable, and improves the powder removal effect.

[0013] Furthermore: the inclined setting of the collection trough utilizes gravity to achieve automatic flour collection, and the discharge hopper guides the collected flour to the collection bag. The detachable collection bag facilitates flour recycling and cleaning. The detachable connection design between the discharge hopper and the collection trough facilitates subsequent cleaning and maintenance of the discharge hopper and the collection trough, ensuring the hygiene of the equipment.

[0014] Furthermore: As the part that comes into direct contact with broad beans, the size of the sieve's aperture is crucial to the de-drying effect; a aperture of 3-5mm can ensure that excess flour on the surface of the broad beans can pass through the sieve holes smoothly, while preventing the broad beans from falling out of the sieve holes, thus ensuring that no material is lost during the de-drying process.

[0015] Furthermore: the collection box is used to collect the broad beans after de-powdering. The guide plate can guide the broad beans to fall accurately into the collection box, avoiding the broad beans from falling outside the equipment and causing losses. The design of the guide plate extending into the screening structure further improves the accuracy and efficiency of material collection.

[0016] Furthermore: the anti-detachment component is clearly defined as a baffle structure, which limits its height range and connection method with the screening structure. The baffle structure can effectively prevent broad beans from detaching from the screening structure during vibration.

[0017] Furthermore, the setting of the speed adjustment knob in the control component allows the operator to adjust the speed of the drive motor according to actual needs, thereby changing the vibration frequency of the screening structure to adapt to the powder removal requirements under different working conditions; the electrical connection between the controller and the drive motor enables precise control of the equipment operation and ensures stable operation of the equipment.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. A device for removing excess flour from the surface of broad beans. This device drives a screening structure to generate continuous and stable vibration through a drive mechanism. Combined with the inclined setting of the screening structure, the broad beans continuously move relative to the screen during the sliding process, allowing excess flour on the surface to be fully removed and fall through the screen holes. The flour removal rate can reach more than 90%, effectively ensuring the consistency of the quality of the broad beans during subsequent frying and avoiding problems such as burning and clumping caused by excessive flour after frying.

[0020] 2. In this utility model, the inclined collection trough and discharge hopper design of the flour collection component can quickly gather and collect the excess flour into the collection bag. The collected flour has high purity and can be reused in the powdering process of broad beans, reducing flour waste, lowering production costs, and conforming to the production concept of energy conservation and environmental protection.

[0021] 3. In this utility model, the equipment adopts a high-strength support frame structure, and the connections between the components are firm. The drive mechanism transmits power through belt drive and eccentric connecting rod assembly, which has high transmission efficiency and stable operation. The vibration frequency can be flexibly adjusted by the control component, which can adapt to the needs of de-powdering of broad beans with different humidity and different powdering amounts. The equipment has a low failure rate and a long service life.

[0022] 4. In this utility model, the control components allow operators to easily control the start and stop of the equipment and the vibration intensity through control buttons and speed adjustment knobs. The addition of time relays enables automated control of the powder removal process, reducing manual intervention. At the same time, the detachable connection design of each component (such as the discharge hopper and the collection trough, and the collection bag and the discharge hopper) facilitates the cleaning, maintenance and component replacement of the equipment, reducing the difficulty of operation and maintenance costs.

[0023] 5. In this utility model, the baffle structure on both sides of the screening structure effectively prevents the broad bean paste from detaching from the edge of the screen during vibration, avoiding material loss and pollution to the surrounding environment; the silicone buffer pad at the bottom of the material collection box and the rubber strip on the inner side of the baffle structure reduce collision damage to the broad bean paste during conveying and de-powdering, ensuring the integrity of the broad bean paste and improving product quality.
