Austrian foodstuffs manufacturer Agrana is the European market leader in the field of biological fruit preparations. Here, research and development play a key role, both at product level and in the production processes themselves.
The MX by KNOLL Maschinenbau was used on a trial basis as part of a new fruit processing concept and produced an impressive all-round performance. The task was to collect and convey various fruit varieties in a still frozen state.
A heated MX30R-60/10 was used for the test setup. Its trough-like shape prevents build-up from occurring on the hopper walls while the tapered worm conveyor ensures optimal product removal from the hopper floor. The CIP-compatible axial face seal with torque transfer element facing away from the product allows easy cleaning while intelligent joints make for fast dismantling. By way of an option, an additional extension hopper can be adapted.
The tests at Agrana showed that the MX provides reliable transportation of various fruit media from starting temperatures as low as – 18 degrees (Celsius). It was able to feed the partially still deep frozen fruits directly into the pump. The media were, as planned, reduced by the MX in a controlled way while being conveyed.
The case study shows that the feed hopper pump version of the MX eccentric screw pump is able to effectively support innovative production processes in the foodstuffs industry. The MX is a good choice when it comes to implementing new formulations or new production methods in a way that maximises sustainability and efficiency while ensuring the gentle processing of natural base products.
