The food industry is experimenting with many ways of continuing to grow: one of the most promising is through the optimization of the transformation processes of the raw material, which on the one hand reduces production costs (and therefore offers the opportunity to present itself on the market with competitive prices while maintaining a high quality of the product) while on the other it helps to minimize waste.

This last attention is more and more urgent, especially today that resources are gradually more limited while the world population continues to grow at a rapid pace: the issue is of primary importance, so much so that it has also been addressed by major international events including Expo Milan 2015.

The industrial centrifuges can really be excellent allies for companies in the food sector who want to get the maximum raw materials that undergo the transformation processes necessary to get to the finished product.

A successful experience that has involved us in this sense was the installation of a centrifuge for the recovery of potato starch, made in the summer of 2017 in constant collaboration with one of our customers.

To pack its snacks, famous all over the world, the company carries out a very complex process that begins with the cleaning of potatoes.

At the end of this first phase, the washing and cutting water contains grey starch which, if they are not separated from all the rest, weigh down the load of the waste water plant increasing the risk of malfunctions and breakages, and the consequent production interruptions necessary to allow the restoration of the line.

The installation of a decanting centrifuge upstream of this passage has instead allowed to lighten the system, keep the washing nozzles clean and fully efficient and above all recover the grey starch which can then be reworked and destined for other uses. 

Furthermore, this process optimizes the recycling of water, allowing the same quantity to be used much longer for several cycles: consequently, water consumption is also reduced.

Always in the food sector but for another project, with a small mobile unit Kit P600 we have successfully carried out separation tests on wheat starch from the bread-making waters.

The tests carried out were aimed at verifying the possibility of recovering starch from the water.

After various tests we obtained a smooth and homogeneous paste and a negligible solid residue in the waste water. This paste is also recovered and, once re-processed, can be used again for the production of other bakery products.

Our development department is available to all the realities of the food world that have similar needs and are considering the possibility to include a decanter centrifuge inside the production line: those who have a need of this type can write to us using the appropriate contact sheed.
