Did you know that infrared heat and UV light contribute to the success of your barbecue?

27.07.2017

Most people like to spend their spare time during the hot summer months outside. In order to bring the day to a close after spending the day at the swimming pool or as a welcome change after an exhausting day at the office, families and friends like to gather in the evening for a barbecue in the garden. However, all the grilled meat, be it sausages or steaks, tastes only half as good when the barbecue sauces or the ketchup are missing. A wide range of sauces is therefore an integral part of a successful barbecue.

Infrared and UV light have a significant part in the process of filling the barbecue sauce safely and without germs into the bottles.


Infrared heat protects glass bottles from breaking

If the temperature difference between liquid and glass is greater than 42°C when filling the bottles, there is a risk of heat shock which causes the glass to crack. To keep this temperature difference below the critical level, the empty bottles were rinsed with hot water, then preheated and dried in a steam oven before filling.

This process was very energy-intensive due to the water and the steam, and the steam oven could not be switched off quickly enough during a belt stop. The infrared oven, which is now used to heat the bottles, is more energy-efficient. By means of a PID controller within the infrared oven, it is ensured that the bottles have the correct temperature for filling.

Carbon infrared emitters (CIR®) emit radiation in the medium wavelength and are suitable for this process, since glass absorbs particularly well in this area. In addition, they react so quickly that they can be controlled easily and an overheating of the bottles in the event of a belt stop is avoided.

Ketchup maker goes for clean production air using efficient UV light

The recipes for barbecue sauces or ketchup usually include sugar, tomato paste, vinegar and salt, as well as condiments. This makes the product tasty. However, not only humans but also moulds, yeasts and viruses find that mixture lovely. They present a problem in the production process as they are naturally present in the air, settle down on the intermediate product before it is packaged and make it perish.

In cooperation with Heraeus experts, Wiso Feinkost GmbH, a producer of more than 350 tons a month of condiment sauces for 38 well-known labels, has found a fast and cost-efficient solution to this problem. The room air is filtered and disinfected with UV light, so that the product will be non-perishable even without adding preservatives.

"In the end, you want a solution that reliably and lastingly disinfects the air", says managing director Alex Wiegand. A cost-efficient and pragmatic solution was found in an advisory meeting wit hthe Heraeus UV experts. The precisely calculated number of ozone-free UV lamps was installed in a commercially available, washable HEPA filter. The efficient method is quite simple:

The viruses and mould spores have different sizes and properties. While mould spores are relatively large and can be caught by the filter, viruses are too small to be retained. Therefore, they get inside the filter where they are inactivated by the UV light. The mould spores already caught can be exposed to the radiation for a longer time. That way, they are inactivated with little expenditure of energy.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
