Weighing and dosing

Weighing and dosing bulk products into a process

It is often necessary to weigh and dose powder, amongst other bulk materials, into a process. Let’s take the addition of sugar into a mixer as an example from the food industry.

According to the recipe, a total of 150 kg of sugar must be added to the mixer. The conveyor system used requires ten conveying cycles of 15 kg each. Depending on the design of the system, delivery rates of up to 4 t / h are also possible. The accuracy of the system is 99 – 99.7% of the target weight to be achieved.

The removal from different pick-up locations is possible as well as the adjustment and storage of recipes. A quick intervention in the process is possible via the device control’s intuitive touch display. In addition, the entire process can of course also be controlled fully automatically.

The Volkmann CONWEIGH is a combined conveying and dosing system and is usually used for adding quantities from 2 kg upwards per unit.

Conveying and dosing in the food sector

Conveying and dosing in the food sector

Conveying and dosing of powders and solids in the food sector

In regards to bulk goods the food industry is very interesting because hardly any other sector can offer such a variety of different powders, granules and bulk or piece goods.

A wide variety of handling tasks for example the finest powders, corn starch, spices, mushrooms and even bacon cubes. In terms of process technology, the methods for transport and dosing are as diverse 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,  granulated sugar, for example, places so much stress on the mechanical system that powdered sugar is produced, which in turn has a very low minimum ignition energy (MIE), which 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.

Weighed product loading task

Weighed RNT hopper

Pre weigh product batch and load to process on demand

Do you need to add a pre weighed product batch into your process? Our modified bag loading weighing station – RNT 180 makes it possible to safely and reliably introduce a pre-weighed quantity into your process, for example into a mixer.

The various ingredients can be pre weighed and loaded into the station before use utilising the inbuilt weighing system. As soon as required, the whole load can be easily transferred into the process by vacuum conveying

The RNT hopper is mechanically isolated to allow accurate weighing. Vacuum transfer of materials ensures minimal dust is generated during loading
