Description

TECHNICAL FIELD

[0001] The utility model relates to airflow mixing machine technical field especially relates to a kind of avoid material residual medicinal airflow mixing machine. BACKGROUND

[0002] Airflow mixing machine is a kind of equipment widely used in pharmaceutical, chemical, food and other industries, mainly used for uniformly mixing different granular or powdery materials. Its working principle is that, by the action of airflow, the material forms fluidized motion in the mixing cylinder, so as to realize rapid and efficient mixing effect. However, the existing airflow mixing machine generally has the problem of material residue in actual use, especially on the inner wall of the mixing cylinder, the material is easy to adhere and gradually accumulate, which not only affects the uniformity of mixing, but also may cause cross contamination, affecting product quality. At present, the airflow mixing machines on the market are mainly divided into two categories: one is the traditional airflow mixing machine, and the other is the improved airflow mixing machine. The traditional airflow mixing machine usually adopts simple airflow injection method, which brings the material in the mixing cylinder for mixing by high-speed airflow. However, in the mixing process, the material is easy to form an adhering layer on the inner wall of the mixing cylinder, especially under the condition of high humidity or high viscosity of the material, the adhesion phenomenon is more serious. The improved airflow mixing machine increases the vibration device or scraper mechanism on the basis of the traditional one, trying to reduce the material residue by mechanical means. However, these improvement measures have limited effect in actual application. Although the vibration device can reduce the material adhesion to some extent, it cannot completely remove the residues on the inner wall, and the vibration device itself is also easy to wear out after long-term use, affecting the service life of the equipment.
