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.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
