Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to an air separation device for cleaning impurities in flour processing. Background Technology

[0002] As is well known, air separation devices are key equipment in flour processing used to remove light impurities (such as wheat husks, straw, and dust) and regulate material flow. Their core principle is to achieve separation by utilizing the difference in density between airflow and material.

[0003] A utility model patent with patent authorization announcement number CN222659263U discloses a wind classifier for wheat flour processing, which includes a mounting base and a support leg at the bottom of the mounting base. The mounting base is equipped with a storage cylinder. A transition box is fitted onto the bottom surface of the discharge port. A square discharge port with a through structure is opened on the bottom surface of the transition box. A removal cylinder is provided below the discharge port. A through groove adapted to the inner wall of the discharge port is opened on the removal cylinder. An adjustment device for flow control is provided in the through groove. An air inlet pipe with a through structure is passed through one end face of the removal cylinder. A collection bag is fitted onto the opening on the other side. A collection port is also opened on the bottom surface of the removal cylinder at the corresponding position of the through groove.

[0004] However, existing wind separation devices used for cleaning impurities in flour processing also have certain drawbacks. Most existing wind separation devices used for cleaning impurities in flour processing directly use blowers, air ducts and other structures to complete the wind separation of wheat raw materials. Since there are many large particles such as gravel in wheat, simply performing direct wind separation will result in poor separation effect. Utility Model Content
