The bulk material flies off a conveyor belt at a speed of about 3 m/s and is recorded by a colour line scan camera. Behind the camera line of sight, the unwanted objects are blown out of the material stream by individually controlled nozzles while still in flight.

The sensor consists of commercially available hardware and measures the spectrum of the reflected light in the near infrared by point measurement. Here, for example, the firmness of tomatoes was examined - a quite reliable criterion for freshness. Through machine learning, the scanner was trained to assess the firmness and thus the freshness from the course of the spectrum.

Food quality and agriculture

The value chain begins with agricultural production, but in perspective it includes further process steps and processing steps. With the aid of innovative concepts for automation and new types of sensor technology, Fraunhofer is building a data-based agricultural ecosystem - an "Agricultural Data Space" that is set to become a milestone in digitised agriculture. Food is controlled and sorted during production. The use of spectral information beyond the R-G-B facilitates classification.

Our projects and products in the field of food quality and agriculture#

Food quality through sorting systems

Sorting systems are used for the control and quality assurance of food. Our multispectral workbench enables objects to be accurately examined in the entire wavelength range.  

DigiVine

Digitalisation in the value-added network: natural and environmentally friendly viticulture and increased labour efficiency while saving resources and costs.

Agriculture

The "COGNAC project" is about helping agriculture to become more sustainable and efficient.

 

Detection of pyrrolizine alkaloids (PA) in plants

The detection of PA in plants and sorting of PA-contaminated medicinal plant products is a joint project of the Fraunhofer IOSB and the Julius Kühn Institute Berlin

FoodScanner

The Food Scanner determines the degree of freshness of food. The mission behind it is the rescue of food.

 

Data fusion in the "FriDa - Fresh Data" project

The aim of the project is to reduce food waste with the help of NIR spectroscopy and additional sensors along the food supply chains.

GrapeSort

The theme of the "Grapesort grape sorting project" is the optical sorting of grape berries by quality, which ensures improved separation of unwanted particles.
