Saving energy while warming up snacks

06.10.2014

New flow concept applies heat to food in targeted manner

In modern ovens, heated air circulates evenly throughout the oven space. When cooking small quantities of food such as frozen pizza, this creates unnecessarily high energy costs. The BINE-Projektinfo brochure “Creating microclimates in ovens” (10/2014) describes the development of a demonstration oven that can save up to 40% of the energy.

In particular, uniform heating of the entire oven interior leads to a disproportionately high energy consumption if the intention is only to warm up small dishes.

However, there are numerous possibilities for blowing hot air at a body. The scientists tested various flow concepts with a pizza dummy. Highly promising was a model where the frozen product is enveloped in a hot air stream like in a bell.

The result of the project is a demonstrator with standardised oven dimensions. This is primarily designed for frozen pizza and similarly sized cooking products. It requires around 40% less energy to cook a pizza than a standard state-of-the-art oven. In the long term it is intended to adapt the flow and heating concept to other cooking products.

The research project was managed by the E.G.O. Group – which supplies manufacturers of household appliances – in collaboration with the Institute for Mechanical Process Engineering at the University of Stuttgart.

About BINE Information Service

Energy research for practical applications

The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
