As part of Minebea Intec’s customer care, regular on-site visits are carried out for all our customers to check that their systems are running smoothly and to collect any feedback. At this customer visit, a particular problem came to light in discussions with the Production Manager. When filling two-chamber tubs with yoghurt and various cereals, time and again there were unwanted, uncontrollable deposits of substandard product residues. The manufacturer pinpointed the problem to the filling process and to the particular properties of the products.

The cereals naturally have a low fat content, which results in the cereal dust adhering to the walls of the filling system chamber. This then clumps and can fall into one of the tubs at any time. The tubs are sealed with an aluminium foil lid straight after filling, so a visual quality control check is out of the question.
