Dust Purification in Pharmaceutical Production

Dust Purification equipment is not only used in industries such as food, chemical industry, and foundry that consume a lot of energy and generate serious dust, but also is indispensable in the pharmaceutical industry. Pharmaceuticals have higher requirements on the cleanliness of the workshop. A large amount of dust will be generated in the production process of the tablet press, granulation room, batching room, and feeding room of solid preparations. Dust removal and purification are required to achieve various cleaning indicators and be put into normal production.

The amount of dust produced by pharmaceutical factories is relatively small, but its harmfulness cannot be underestimated. The particle size of pharmaceutical dust is small. If it is not cleaned up in time, it is easy to be suspended in the working environment and deposited on the ground, equipment and corners for a long time, and it will cause wear and tear on the spare parts of the production equipment and increase maintenance costs. In addition, the scattered drug dust may also cause cross-contamination between products, and the drug workshop needs to be at a higher cleanliness level to ensure the quality of the drug.

The diversity of pharmaceutical ingredients determines the complexity of dust components, and employees in the workshop are prone to respiratory diseases such as pneumonia and pneumoconiosis if inhaled for a long time. Some special drugs have allergens, and long-term exposure to drug dust can cause skin diseases such as itching and tingling. In recent years, the voices of paying attention to occupational diseases in the pharmaceutical industry have become increasingly louder, and the process of adopting dust removal equipment in pharmaceutical factories has also been accelerated.

The Dust Collector is suitable for the purification and dust removal of pharmaceutical production lines, tablet presses,

granulators, mixers, ingredients, mixing materials, vibrating screens, pulverizers, weighing, capsules, and traditional

Chinese medicine pretreatment in pharmaceutical factories.

Central Dust Collection System

The use of a central dust removal system can effectively remove dynamic and static dust in the workshop. The industrial Suction Hood captures the dust-laden air generated in the production process at the dust-raising point. Under the action of the suction force of the fan, the dust-laden air reaches the dust collector through the pipeline for filtration. The filter cartridge or filter bag in the dust collector separates the dust from the air and falls into the ash bucket, and the purified clean air is discharged from the exhaust port.
Due to the particularity of medicines, pharmaceutical workshops have high requirements on the cleanliness of the environment, and the dust particles of medicines may also have strong sensitization, which may also pose a potential threat to the occupational health of operators. The value of dust removal equipment is thus Reflected, it provides users with a cleaning method that improves cleaning efficiency, saves more valuable time, and reduces safety hazards.

Combustible dust and explosion protection requirements

Many pharmaceutical dusts are combustible dusts. There are many electrical equipment on site, and there is sufficient air in the space. When the dust concentration reaches the limit, it is easy to cause dust explosion when it encounters an ignition source, resulting in immeasurable losses. For example, in the tablet workshop, weighing, mixing, sieving, packaging, etc. will generate dust, and the dust composition will be more complex, including talc (some tablets may be sugar-coated). This dust may be under certain conditions. It will cause explosions and affect production and safety, so explosion-proof dust removal systems need to be considered.

(Explosion-proof) Dust Collector

Moland MLWF series dust collectors can be used to handle dust in pharmaceutical production processes. The modular design of the dust collector has a pleated filter cartridge dust collector, which can well meet the dust removal needs of pharmaceutical dust. Suitable filter media can be selected according to different dust amounts and dust types. For some toxic pharmaceutical dusts, it is necessary to perform non-contact safe replacement of filter elements and ash pouring, and we can also provide customers with bag-in-bag-out solutions.


The Moland explosion-proof dust collector can deal with the overpressure generated by a potential explosion. This dust collector is equipped with an explosion-proof pressure relief plate or a flameless explosion relief valve. In the event of an explosion accident, the shock wave and flame generated by the explosion can be released to a safe area. Minimize the harmful effects of explosions.

Considering that the pharmaceutical production process has different production lines, Moland will design a dust removal plan according to the equipment placement and layout of the workshop, the type of dust, the number of work points and the powder production volume of each work point, so as to help pharmaceutical companies more Good control of dust problems and escort for safe production in the workshop.

If pharmaceutical companies do not pay attention to the dust problem, it will not only pollute the environment, affect product quality, but also cause dust explosions. With the further development of the pharmaceutical industry and the further improvement of the country's environmental protection requirements, the application of dust removal technology in the pharmaceutical industry will become more and more extensive.
