Porosity maps give an ‘airy’ image of fruit and vegetables

See the internal structure of your product through 3D X-ray based porosity mapping.   The porosity of a fruit or vegetable quantifies the amount of air spaces inside the product. The porosity strongly determines to what extent and how it dries out, or how well the product responses to modified or controlled atmopshere conditions.   A horticultural product transports

Managing supply uncertainty in operational production planning – A whitefish case study

Managing supply uncertainty by a formal stochastic programming approach demonstrates how expected profit may be increased due to more robust production plans.   Production planning Operational production planning deals with establishing optimal production plans. A production plan determines which production lines to utilize, which products to produce and allocation of resources such as personnel and machines.

Intermediary Real-Time Trajectory Interpolating with Cubic Hermite Splines

Real-time trajectory interpolation allows a Python-based sensor-integrating application to real-time control a Franka Emika robot. Application development in Python is much faster and easier than in C++.   When robot motion generation for a processing task is dependent on real-time sensor feed-back from the processing tool, the motion must be, by it’s nature, generated at the temporal micro to meso level in real-time. Some open robot controllers allow real-time trajectory feeding at the micro level. These are obvious candidates for such real-time sensor-based motion applications.   If a given application only requires real-time trajectory generation at the meso level, interpolation may be utilized for alleviating the application from the micro real-time requirement of the robot controller. This, in turn, opens for freedom of choice of the

Designing within the circular economy

How can the food industry and their equipment vendors use design as a tool to enter the circular economy?  Circular design is a tool used in the circular economy. The future must become more sustainable than what it is today, and designers can pave the way forward by using circular design.   Circular design In circular

Barriers to increased automation and technological development in food processing

The most important barrier for introduction of technology with artificial intelligence in processing of food in Norway, is the complexity of the new technology. The new technology is demanding for firms to adopt with their current knowledge base. Increased automation Increased use of automation with artificial intelligence has changed the production processes in almost every

Robotic handling of compliant food objects by robust learning from demonstration

Today, robots lack the visual, tactile and cognitive intelligence of humans to perform complex handling and processing tasks. We show how to endow robots these abilities and how to teach them to handle complaint food objects by Learning from Demonstration. The robotic handling of compliant and deformable food raw materials, characterized by high biological variation,

Traceability of hides through the supply chain

Hides are one of the most important rest raw materials or plus-products produced by the meat industry as they are further processed and used in leather production. The hide supply chain consists of a producer (farm), slaughterhouse, hide processor and a tannery. A lot of data is generated in this supply chain but there is

Information sharing strategies in whitefish supply chain

Information sharing is one of the main supply chain strategies for reducing uncertainty and is vital for supply chain efficiency. All actors can benefit from sharing relevant information in a timely manner and improve supply chain coordination. Whitefish supply chains are complex in nature due to seasonal variations, high supply uncertainty and rapid quality deterioration

Research exchange from India to Norway

An Indian PhD student from IIT Kharagpur has been on a research exchange to SINTEF Ocean in the RE-food project working with the Norwegian whitefish supply chain in the iProcess project. In iProcess he worked together with researchers at SINTEF and NTNU with optimizing  the delivery strategies to minimize travel distance as well as the
