For us at CELMI srl, who have specialized in the design and production of industrial weighing systems

for over 40 years, every market is important and strategic, such as the coffee market for example.

Each bean contains a world of aromas and flavors, an emotional journey that starts from the field and ends in the cup. It is in the final stage of processing that the coffee beans are perfected. This last processing step, in fact, eliminates unsuitable beans, ensuring that only the best contribute to creating a tasting experience unique. To carry out this important process, optical sorters are used which, depending on the signals detected by their optical system, control a pneumatic device which physically divides the product to be rejected from the one recognized as “compliant”. It is of fundamental importance to correctly weigh the “non-compliant” and rejected product to optimize production.

It is in the final waste weighting phase that we at Celmi support all the professionals who produce optical sorters. In fact, inside these machines there are our bending load cells which quantify the weight of the waste with maximum precision, making it possible to optimize the production cycle.

These load cells are precision instruments used for weighing small loads. Suitable for single cell applications or more complex weighing systems, they guarantee precise and reliable results. Made to industrial quality and reliability standards, Celmi bending load cells ensure strength, longevity and precision.

Our load cells designed for these types of applications are:
