Vacuum sieving pharmaceutical ingredients

Leading herbal medicine manufacturer increases throughput rates using the Russell Compact Airswept Sieve™ in its vacuum conveying line

Natulab is the 10th largest pharmaceutical company in Brazil and the top company in the country to manufacture herbal medicines. It is also the 5th largest manufacturer of over-the-counter medicines and has grown rapidly in recent years in the market as the demand for pharmaceutical products has grown.

To meet this rise in demand, Natulab sought to build a new production line at its plant in Brazil, one which required a fully enclosed screening solution that could be integrated into a vacuum conveying line. Its overall aim was to find equipment that could safely screen pharmaceutical ingredients, and eliminate oversize contamination, lumps, and foreign bodies from the product.

Having previously used a vibrating sieve that required frequent mesh screen replacement due to poor sieving performance, Natulab sought a more efficient solution to improve throughput rates and reduce production downtime caused by continual machine stoppages. After consultation with expert Russell Finex sales engineers, the Russell Compact Airswept Sieve™ was recommended as the ideal solution.

Installed at the start of this new production line at Natulab, the ingredients pass through to the sieve via a vacuum conveying system. Whilst the good product passes through, the waste and oversize product is removed through a discharge outlet on the sieve. With the Russell Compact Airswept Sieve™ now in place, the entire process is 50% faster and 300% more productive, taking 20 minutes and sieving between 1000-1200kg/hr, vastly reducing production time and increasing production output.
