The working principle of the air jet sieve airflow screening instrument began research and development of 510-179 in 2017. With the increasing prevalence of Huimeike air jet screens in users' daily screening work, there is also a growing exploration of the working principle of this new type of screening instrument. Since 2017, Huimeike has actively maintained communication with foreign research and development institutions, even though it was not available domestically. Eventually, it introduced the high-efficiency screening method of air jet screening and airflow screening instrument, which has been well received by a large number of domestic users. The working principle of the instrument is to use air flow to blow and disperse particles, negative pressure to suck away small particles, leaving behind large particles that cannot be sieved. The subsequent processing is similar to that of a regular vibrating screening instrument.

In 1998, after the promulgation of the revised version of the Drug Production Management Quality Standards by the National Medical Products Administration, a step-by-step, variety based, and dosage based GMP work plan was successively issued. From 1998 to 2004, GMP certification was implemented for blood product enterprises, powder injections (including freeze-dried powder injections), large volume injection genetic engineering products, small volume injections, and radioactive drug injections. Otherwise, production would be immediately suspended; Before June 30, 2004, the production of all pharmaceutical preparations and raw materials such as microcrystalline cellulose and lactose in China must comply with GMP requirements and obtain drug GMP certificates, otherwise their production will be suspended; On the basis of fully implementing GMP in formulations and active pharmaceutical ingredients, traditional Chinese medicine decoction pieces, medical oxygen, in vitro biological diagnostic reagents, pharmaceutical excipients tested by Huimeike HMK-200 air jet sieve, radioactive products implanted in the body, and medical devices have been included in the scope of GMP certification. Relevant enterprises that fail to meet GMP requirements within the prescribed period and have not obtained drug GMP certificates will be stopped from production.
