Description
Technical Field

Background
With the rapid development of high-performance structural material technology and advanced material processing technology, people put higher demands on toughness, rigidity, environmental protection, recycling property, service life and the like of materials. Therefore, a technology for improving the performance of various aspects of materials by treating the surface of the materials to change the properties of the surface of the materials, such as morphology, chemical composition, and texture, has been rapidly developed in recent years. Among various surface treatment methods such as physical treatment, chemical treatment, mechanical treatment and the like, the plasma surface treatment technology is rapidly developed due to the advantages of high cleaning efficiency, low energy consumption, no waste and the like. At present, the plasma processing technology of different material shapes and materials has been divided into different industries. Vacuum plasma has been widely used in industrial fields due to its good repeatability and full coverage. But is primarily used in the surface treatment of bulk materials.
Powder materials, including spices in the field of food and industrial powder materials in the field of industry, are very easy to agglomerate due to large surface area, the reaction of plasma and the materials is limited to the surface of the materials, and only the surface layer of the powder materials in a stacking state can be treated in the plasma environment. Therefore, in the process of plasma treatment of the powder material, the portion not exposed on the surface is often not subjected to plasma treatment due to agglomeration among the particles, and it is difficult to completely treat the surface of the particles, resulting in incomplete and uneven treatment and poor treatment effect.
Chinese patent (CN 201380032762.3) discloses a powder plasma processing device.

The powder plasma processing apparatus can effectively process the powder by controlling the time for which the powder is in contact with the plasma. However, since the powder freely falls from the powder supply portion and the spatial positional relationship inside the chamber is relatively fixed, only the powder distributed on the surface layer may be subjected to plasma treatment, and uniformity of the treatment effect is difficult to ensure.
Therefore, it is an urgent technical problem to be solved by those skilled in the art to provide an atmospheric pressure drum-type powder modifying apparatus, which improves the structural composition and connection manner inside the drum based on the existing atmospheric pressure plasma powder processing technology, fully utilizes the discharge space, and improves the uniformity of the plasma powder material processing.
