Dry air is most important during the Production Too As during the storage of pharmaceutical products. Most materials used in drugs today are hygroscopic and any absorption of moisture during the manufacturing process will affect the final weight, quality and durability. When hygroscopic components are combined and weighed, it is very important that the goods’ weight is not affected by absorption of moisture from the surrounding air. In powder form, moisture will affect the flow, caking, Compaction and strength properties of the fabricated strong form. Yeast, bacteria and molds need a certain amount of Moisture to promote growth. Controlling relative humidity is most likely one of the most important components in maintaining a sterile environment. A cool dry environment generally enables faster production, a better quality product and a longer shelf life. The huge majority of tableting processes require humidity control between 20 and 35%RH at 21 to 24°C.
In most pharmaceutical Desiccant systems, the best moisture Load is from the brand new air component that is typically between 5 and 20% of the entire supply air volume. According to moisture gains Throughout the region, it might only be necessary to profound dry the atmosphere part using a pre-cooling coil > 10°Cdp and a desiccant dehumidifier. Dehumidifier capacity is controlled by an RH sensor installed in the return air duct. This simple design is often sufficient to maintain the compulsory RH inside the room. Ac systems with a low fresh air volume and rooms with excessive moisture gains from high infiltration rates adverse room pressures, regular door usage, product loading, etc, will normally require all the fresh air and a proportion of the return air to be dried.
In Europe molecular sieve is used in pharmaceutical applications. In the United States it is often the desiccant of Option for pharmaceuticals and bio-chemicals and/or reagents. Although PHARMACEUTICAL DESICCANT sieve is a bit greater in cost per unit due to its extremely Large range of adsorptive capabilities and greater capacity at low relative Humidity it is often the best value. Deficiency of Government approval for the Molecular sieves in food and drug packaging has regrettably limited its widespread use. Independent testing suggests that molecular sieves meet or exceed government requirements. Presumably, however, the business has been reluctant to Fund the costly and time consuming testing that is necessary for government approval.
