In the process of pharmaceutical production, due to friction, there is a lot of static electricity in the medicine or medicine utensils, which causes the dust in the air to adsorb on it, and affects the quality and qualified rate of the product. Therefore, in the process of pharmaceutical production and cleaning of medicine utensils, it is necessary to effectively eliminate the static electricity, so as to improve the quality of the product. For this special pharmaceutical industry, to improve the quality of products, it is necessary to eliminate the dust on the products, but the dust is adsorbed on it due to static electricity, so to remove dust, it is necessary to eliminate static electricity. More common equipment are: electrostatic ion gun, electrostatic ion nozzle, electrostatic ion rod, etc.
