The machine’s compression support is based on robust columns linked together by strong cast iron structures. Upper and lower precompression and main compression rollers are housed within this robust frame and fixed on both sides. Both rollers have the same diameter, thus allowing flexible adjustment and optimal performance with a wide range of products. This exceptionally sturdy structure—an essential requisite for the production of quality tablets— guarantees compression forces up to 100 kN with maximum reliability.
To keep noise level at a minimum, Prexima has been fitted with sealing on its machine doors, sound-proof panels in the basement and anti-vibration feet. Prexima has been tested at the anechoic chamber at the University of Ferrara (Italy), which has offered IMA recommendations for the choice of the best technical solutions and sound-proof materials. The result is a very quiet machine with minimum vibrations.
Prexima is fitted with the new XIMA HMI, which was awarded the 2015 A’ Design Award for its strategic role in improving the operators’ efficiency. The control system is features linearity, intuitiveness, iconicity and scalability. XIMA follows the principle of linear navigation, in that each action of the user on the HMI corresponds to only one control signal. In addition XIMA is based on the principle of natural mapping: the synoptic uses spatial correspondence between the layout of the controls and the devices being controlled, thus reproducing the main machine workflow.
The icons of XIMA serve as perceivable indicators that suggest appropriate functions to the user. The principle of scalability, in the end, enables XIMA to be scaled to multiple devices and multiple machines.
Studies & Tests
Tests have been a key role in the development of Prexima right from the start. The most difficult-tomanage products have been tested, allowing a timely feedback on the machine design. IMA Active is still performing trials with several formulations: here are two of the most meaningful.
