Description

Technical Field

[0002] Dry powder inhalers are formulations that deliver fine particle drugs, alone or mixed with a carrier, to the lungs through a special inhalation device. Spray drying is a method of converting drug solutions or suspensions into dry powders using spray drying technology, which is suitable for the preparation of heat-sensitive drugs. Spray freeze-drying combines spray and freeze-drying technologies to prepare low-density porous particles, improving drug airflow compliance and lung deposition performance.

[0003] In the processing of dry powder inhalers, spray dryers are required for micronization. Current spray dryers have a simple structure and are not easy to clean. They are mostly cleaned by rinsing with water. During cleaning, the canister walls cannot be scrubbed, resulting in a large amount of drug still adhering to the canister walls, which affects the quality of the drug.

[0004] Therefore, the spray dryer needs to be redesigned to facilitate automatic cleaning. Utility Model Content

[0029] refer to Figure 3 An overload protection module 21, which works in conjunction with the motor 8 and the water pump 13, is fixedly connected to the upper left side of the control cabinet 17.

[0030] As a technical optimization of this utility model, by setting an overload protection module 21, the motor 8 and the water pump 13 can be further protected to prevent the motor 8 and the water pump 13 from being damaged due to overload.

[0031] refer to Figure 3 A 5G module 22 is fixedly connected to the upper left side of the control cabinet 17, behind the overload protection module 21.

[0041] The working principle and usage process of this utility model are as follows: In use, the water pump 13 and motor 8 are first started via the control terminal 20. The input end of the water pump 13 generates suction to absorb water through the inlet pipe 14, causing the water to be discharged from the output end of the water pump 13. The water is then sprayed onto the inner wall of the tank 1 through the water delivery pipe 12 and the annular water outlet box 3, rinsing the inner wall of the tank 1. Simultaneously, the output end of the motor 8 drives the vertical rod 9 to rotate, which in turn drives the scraper 10 and the metal soft brush plate 11 to rotate, thus scrubbing the inner wall of the tank 1. After washing, the water pump 13 and motor 8 are turned off, and excess sewage is discharged through the discharge pipe 7. Next, hot air is blown into the tank 1 through the air duct 15 and the circular hot air box 4 to dry the inside of the tank 1. At this time, the humidity sensor 18 is used to detect the humidity inside the tank 1 in real time. The detection data is sent to the data processing module 19, processed by the data processing module 19, and then sent to the control terminal 20. When the detection data is the same as the preset data, the tank 1 is completely dry, and micronization preparation can continue to be carried out to achieve the effect of easy cleaning.

[0042] In summary, this micronization preparation device for dry powder inhalers, by incorporating a tank 1, support legs 2, annular water outlet box 3, annular hot air box 4, annular spray box 5, mounting plate 6, discharge pipe 7, motor 8, vertical rod 9, scraper 10, metal soft brush plate 11, water supply pipe 12, water pump 13, water inlet pipe 14, air supply pipe 15, material supply pipe 16, control cabinet 17, humidity sensor 18, data processing module 19, and control terminal 20, solves the problems of current spray dryers, such as simple structure, inconvenience in cleaning, reliance on water rinsing for cleaning, inability to scrub the tank wall during cleaning, resulting in a large amount of drug still adhering to the tank wall, thus affecting drug quality.
