Description

Technical Field

[0001] This utility model relates to the field of pea processing, specifically a peeling device for processing pea flour. Background Technology

[0002] Pea flour, a traditional food ingredient rich in nutrients and with a delicate texture, is widely used in various flour products and specialty foods. However, in traditional pea flour processing, the pea skins contain a significant amount of coarse fiber and pigments, which are difficult to remove completely and often end up mixed into the finished flour. This not only affects the color and fineness of the flour but also reduces its taste and overall quality. Furthermore, traditional processing equipment often employs a single grinding and sieving process, lacking an effective peeling mechanism, resulting in incomplete separation of the pea skins from the flour, low flour yield, and inefficient resource utilization. Therefore, overcoming these technical problems and deficiencies is a key issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to overcome the defects described in the background art, thereby realizing a peeling device for pea flour processing. This device effectively peels peas during processing by crushing, multi-stage grinding and sieving, and combining the air separation effect of a high-pressure blower. This achieves efficient separation of pea skins and flour, significantly improving the purity and edible quality of pea flour. For residual flour that remains after multiple grindings, the system separates and packages the pea skins. The system then re-transports them to the second circular sieve of the first flour mill for cyclic sieving and grinding, forming a closed-loop processing flow. This further enhances the thoroughness of peeling and the flour recovery rate, comprehensively improving the overall processing efficiency and flour yield.

[0004] To achieve the above-mentioned objectives, the technical solution of this utility model is: a peeling device for processing pea flour, comprising a high-pressure blower, a dough receiving frame, a bean skin frame, a crusher, and multiple flour mills, wherein the multiple flour mills are connected in series, the feeding end of the dough receiving frame is connected to all the flour mills respectively, the bean skin frame is connected to the flour mill at the tail end, one end of the high-pressure blower is connected to both the dough receiving frame and the bean skin frame respectively, the other end of the high-pressure blower is connected to each flour mill, and the crusher is arranged in series at the front of the flour mills.

[0019] The peeling device for pea flour processing of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] See Figures 1-2 This embodiment describes a peeling device for processing pea flour. By crushing, multi-stage grinding, and sieving the peas, combined with the air separation effect of the high-pressure blower 1, the device effectively peels the peas during processing, achieving efficient separation of the pea skins and flour. This significantly improves the purity and edible quality of the pea flour. For any residual flour remaining after multiple grinding stages, the system separates the pea skins and packages them. The system then re-feeds these skins to the second circular sieve 8 of the first flour mill 5 for cyclic sieving and grinding, forming a closed-loop processing flow. This further enhances the thoroughness of peeling and the flour recovery rate, comprehensively improving overall processing efficiency and flour yield. In this embodiment, the device mainly includes a high-pressure blower 1, a dough receiving frame 2, a pea skin rack 3, a crusher 4, and multiple flour mills 5. These flour mills 5 are connected in series, with at least four mills. The first flour mill 5 includes a hopper 6 at its uppermost end, with a grinder 7 and a circular sieve 8 sequentially arranged at the bottom of the hopper 6. The crusher 4 is connected in series at the front of the flour mill 5. The discharge port of the crusher 4 is located above the hopper 6. The high-pressure blower 1, the dough receiving frame 2, the bean curd sheet frame 3, the crusher 4, the grinder 7, and the circular sieve 8 are all mature existing technologies, and their working principles and control methods are not the focus of this application, so they will not be described in detail here.

[0022] Peas are pulverized inside the grinder 4 until they are ground to a suitable particle size for the mill 7, significantly reducing the workload of the subsequent mill 7, shortening the grinding time, improving overall processing efficiency, and helping the subsequent mill 7 to process the material evenly, avoiding uneven grinding caused by particles that are too large or too small, thereby improving the fineness and quality consistency of the flour. The pea particles are then discharged into the hopper 6. At this point, the pea particles in the hopper 6 are ground by the mill 7, separating the pea flour from the pea skins. The ground peas are then sieved through the circular sieve 8; the refined pea flour is directly packaged, while the coarse pea flour and pea skins enter the next flour mill 5.

[0023] The flour mill 5 at the beginning has two circular screens 8, and the feed inlet of one of the circular screens 8 is connected to the bottom discharge port of the grinder 7. The hopper 6, the grinder 7 and the corresponding circular screen 8 are connected in series.

[0024] The rear flour mill 5 includes, from top to bottom, a dust collector 9, an airlock 10, a grinder 7, and a circular sieve 8, connected in series. The airlock 10 prevents dust spillage or material backflow caused by airflow reversal, ensuring the airtightness of the entire system. Each flour mill 5's dust collector 9 is connected to the discharge port of the circular sieve 8 of the preceding flour mill 5. The dust collector 9 and airlock 10 are mature existing technologies; their working principles and control methods are not the focus of this invention and will not be described in detail here.

[0025] After being sieved through the circular sieve 8, the coarse pea flour and pea skins enter the dust collector 9 and airlock 10 of the next flour mill 5, and then re-enter the grinder 7. After grinding, they are sieved through the circular sieve 8 and diverted. Then, the coarse pea flour and pea skins enter the next flour mill 5, and this process is repeated until the peas have undergone four grinding stages, achieving efficient separation of pea flour and pea skins. Through multi-stage grinding and sieving processes, pea skins and flour are effectively separated, greatly improving raw material utilization and flour yield, and significantly enhancing the purity and edible quality of pea flour.

[0026] To achieve the movement of pea flour and pea skins. See also Figures 1-2 In this embodiment, the feeding end of the dough receiving frame 2 is connected to all the flour mills 5, and the bean curd sheet frame 3 is connected to the flour mill 5 at the tail end. The dust collector 9 and the airlock 10 are also installed at the top of the dough receiving frame 2 and the bean curd sheet frame 3, and are connected in series with the dough receiving frame 2 and the bean curd sheet frame 3, respectively. The dough receiving frame 2 and the bean curd sheet frame 3 are mature existing technologies, and their working principles and control methods are not the focus of this application, so they will not be described in detail here.

[0027] One end of the high-pressure blower 1 is connected to the dough receiving frame 2 and the bean curd sheet frame 3, respectively, and the other end of the high-pressure blower 1 is connected to each flour mill 5. The air inlet of the high-pressure blower 1 is connected to the discharge port of the corresponding circular sieve 8 of the first flour mill 5 and the discharge ports of the circular sieve 8 of the other flour mills 5. The air inlet of the high-pressure blower 1 is also connected to the dough receiving frame 2 and the bean curd sheet frame 3, respectively, and the air outlet of the high-pressure blower 1 is connected to the feed port of another circular sieve 8 of the first flour mill 5.

[0028] Pea flour and pea husks are moved between the flour mills 5 under the negative pressure and air separation action of the high-pressure blower 1. Under the action of the high-pressure blower 1, the refined pea flour is packaged through the dough receiving rack 2, while the shaved pea flour is packaged through the pea husk rack 3. During this process, the pea husks that are not completely de-dusted after four grindings are transported back to the second circular sieve 8 of the first flour mill 5 for further grading, grinding and sieving, forming a closed-loop processing system, which further improves the thoroughness of de-dusting and the flour recovery rate.

[0029] The method of using the peeling equipment for pea flour processing according to this utility model is as follows: First, the peas are crushed inside the crusher 4 until they are crushed into particles of a suitable size for grinding by the grinder 7. Then, the pea particles are discharged into the hopper 6. At this time, the pea particles in the hopper 6 are ground by the grinder 7, separating the pea flour and pea skins. After grinding, the peas are sieved through the circular sieve 8. The pea flour and pea skins are moved between the flour mills 5 under the negative pressure and air separation action of the high-pressure blower 1. Under the action of the high-pressure blower 1, the refined pea flour is packaged through the receiving rack 2. The coarse pea flour and pea skins after being sieved by the circular sieve 8 enter the dust collector 9 and the airlock 10 of the next flour mill 5 and re-enter the grinder 7. After grinding, they enter the circular sieve 8 for sieving and are diverted under the action of the high-pressure blower 1. Then, the high-pressure blower 1 causes the coarse pea flour and pea skins to enter the next flour mill 5. This process is repeated until the peas have undergone four grinding processes to efficiently separate the pea flour and pea skins. The pulverized pea skins, free of flour, are packaged using a bean skin rack 3 via a high-pressure blower 1. Furthermore, pea skins that are still not completely de-flourized after four grinding cycles are again conveyed by the high-pressure blower 1 to the second circular sieve 8 of the first flour mill 5 for further grading, grinding, and sieving, forming a closed-loop processing system that further improves the thoroughness of skin removal and the flour recovery rate.
