Tablet Presses Fast Changeover for the Markets of Tomorrow
“Two-thirds of pharmaceutical growth will be concentrated in the pharmerging markets,” pointed out Fette Compacting CEO Olaf J. Müller. Fette began preparing to accommodate these markets years ago.
The Competence Center in Campinas, Brazil, opened in April, and the company now has five comparably equipped Competence Centers worldwide located in the growth markets. “At those Centers, we offer our customers a comprehensive service portfolio ranging from training and consultancy to press trials under production conditions,” explained Müller.
The company has also launched an innovation campaign. As batch sizes continue to shrink, developers are setting their sights on shorter setup times. Fette Compacting is showcasing the FE35 at Achema, which is the second machine in the new FE series. The company claims that it features the fastest changeover of any tablet machine on the market. The FE35 is a single rotary press and it can be equipped with up to 51 punch stations. The maximum production rate is around 37,000 tablets and hour. It only takes about 15 minutes to remove the turret. A new press cell design ensures that machine components are easily accessible during changeover and cleaning.
The die table segments are another new feature of the FE35. Despite a larger pitch circle diameter of 325 mm, the segments weigh no more than segments with a smaller pitch circle diameter. Fette Compacting has also taken a new approach to the design and functionality of the compression rollers.
The FE35 is the only machine in its class with automatic top and bottom compression roller adjustment, compression detection sensors with built-in measurement amplifiers, and drives with a new position sensing system. This has the advantage that no positioning to reference marks is necessary when the turret is replaced. The sensors can be calibrated at the operator console via software.
