Problems solved by technology

[0002] Dry powder inhaler as a pulmonary drug delivery device has been widely used in the treatment of lung diseases. The shell of dry powder inhaler is generally made of plastic, while the extrusion process is used in the production of dry powder inhaler shell, plastic The particles are firstly mixed through the mixing device, and then enter the extruder for extrusion after the mixing is completed. During the mixing process, due to the different densities of different types of plastic particles, stratification occurs, which will cause mixing. Uneven and insufficient materials can easily lead to a decline in product quality and fail to meet product factory standards
