Chocolate challenge

This project called for maximum flexibility on a large scale. Of course, we gladly accepted the challenge, because the medium to be stirred was very tempting: delicious, melt-in-the-mouth premium chocolate in a wide variety of flavors. Who could say no to that...
Passion Chocolat Suisse - that is Maestrani since the brand was created by Aquilino Maestrani in 1852. Since then, the company has been synonymous with high-quality chocolate and chocolate creations in countless flavors and presentations.

In order to meet the high quality requirements for creaminess and tenderness, the stirring process is essential in chocolate production. And it poses a number of challenges for the structure of our Stand agitator with a total height of 3.6 meters:

Various container sizes and heights

Over the years, different containers have become established in production at Maestrani: large, small, sometimes with rollers, sometimes without, sometimes completely open, sometimes closed with a manhole opening. Of course, it was no longer possible to reduce this abundance of containers to a standard container for the stirring process. The agitator therefore had to be able to adapt to the containers.

Our solution:

The first step was to measure all the containers. We were then able to divide them into three categories. For each category, we defined the necessary dimensions for the space in front of the stand agitator. We used the data to construct a base frame with devices that could be folded in and out. These container mounts ensure that the respective container stands securely. Sensors check that the container and the stand fit together and call the digital, touch-based eco-Control automatically retrieves the appropriate data to enable the stirring process.

Different viscosities, different ingredients

Not all chocolate is the same. Dark, milk, with coconut, with hazelnuts... a wide range requires maximum flexibility in the mixing process. High viscosity Masses must be stirred efficiently and homogeneously, while ingredients must be added gently.

Our solution:

We solved this with a powerful agitator that can stir up highly viscous media within a very short time. In order to protect the contents despite this, we combined our gentle Agitator eco-Cup with its low shear forces and gentle mixing.

Various fill levels

The different container sizes naturally resulted in different fill levels.

Our solution:

In order to do justice to this, the size of the agitator also had to be adapted. To do this, we developed special attachments at different heights and in different numbers on the agitator shaft. The cups of the agitator can now be attached and removed quickly and easily. For optimum organization of the process, the stand agitator has a practical suspension system within easy reach for the cups that are not currently required.

Absolute control of the stirring processes

The different mixing containers, mixtures and ingredients to be mixed result in a wide range of requirements for the mixing process. Manual settings take too long, are too imprecise and too complicated. And because of the good reproducibility, they do not make sense here anyway.

Our solution:

Our eco-Control system provides complete management of the mixing processes, known here as recipes. Maestrani can now save countless recipes in a collection and call them up at the touch of a button. Parameters such as speed and stirring time can be freely defined. This means that different stirring sequences with different speeds can be run one after the other in any number. Stir up, stir in, homogenize - everything is possible within the framework of a recipe.

Here is the finished system on site at Maestrani.
