Pharma Technology Inc. offers its completely modular PharmaFlex iSeries 750 CE Dust-Tight Deduster, featuring an air jet and vacuum concept: circumferential dust extraction on the spiral periphery combines with central air jets for extremely efficient dust removal. In parallel tests where tablets were weighed before and after dedusting, the unit removes 40 percent more dust compared to traditional stainless steel spirals with dust extraction through a central tube.
The deduster is comprised of segmented transparent Tritan polymer spirals allowing for 360-degree product viewing — meaning external windows with seals or fastening mechanisms are unnecessary. The robust Tritan material from which the spiral sections are made is resistant to 6-ft. drops, 95 C hot water, common alkaline detergents, and prolonged alcohol exposure. The segmented nature of the deduster’s spirals and central stainless steel modular shaft facilitate easy assembly and disassembly in sections, and allow the height of the spiral to be adjusted incrementally.
All contact parts are contained within the deduster tower, resulting in complete segregation of the dedusting and mechanical areas, with no dust extraction channel through the mechanical base. Wide inlet and outlet chutes allow for increased tablet output, and a patented round throughput chute through the metal detector head provides enhanced detection sensitivity. The advanced deduster can operate to level 3 occupation exposure banding (OEB) during production. The complete tower can be exchanged in five minutes in a dust-tight manner for faster changeover.
The deduster features an acceleration sensor that automatically adjusts vibration intensity to ensure optimal tablet flow and complete self-emptying at the end of a run. Its large touch-screen HMI rotates 180 degrees, and the electrical cabinet’s mounted position at the front of the unit allows it to be oriented in any direction, eliminating the need for mirror image units with double sided presses. The deduster also can be modularly upgraded in the field to a higher containment version.
