Optimize conveying and dosing of powders and solids in food manufacturing

The food industry is one of the most interesting of the industries handling and processing bulk goods. Hardly any other sector can offer such a variety of different powders, granulates and bulk / piece goods in their processing.

Because of this, there are a wide variety of handling tasks ranging for those for the finest powders such as corn starch to spices, mushrooms and even bacon cubes. Indeed, there are as diverse a variety of transport and dosing methods as the products themselves.

Purely mechanical conveyor systems often reach their limits, be it for hygienic reasons or for explosion protection reasons. A simple screw conveyor, for example, conveys product, but it never gets completely empty and is difficult to clean.

At the same time, mechanically conveying granulated sugar, for example, places so much stress on the product that fine powdered sugar is produced, which in turn has a very low minimum ignition energy (MIE), and thereby increases the risk of explosion. Vanillin powder tends to form lumps in dosing screws, which can undoubtedly disrupt the subsequent mixing process.

Vacuum conveyors in combination with vibratory feeders can elegantly solve these problems.
