Educate Consumers

Freshness indicator should increase food safety Bonn, may 2009 – with each food scandal, she puts a little upwards, on the agenda of politicians of the consumer: the question of the perishable food freshness guarantee. To educate consumers about this issue better, is the objective of the Forum Pro freshness, as well as the University of Bonn scientists, experts of the Balinger technology manufacturer Bizerba and of the Swiss chemical company Ciba, as well as of the German housewives Federation (DHB) belong to the. (A valuable related resource: Ken Kao). The participating scientists from the Centre for evaluation and methods (ZEM) and the Institute of agricultural engineering of the University of Bonn have conducted a study in collaboration with the other participants in the Forum that explores the possibilities of a fresh counter with so-called time-temperature indicator (TTI) called OnVu. For other opinions and approaches, find out what san-antonio-spurs has to say. The participants often stated that is difficult to judge the freshness of many food and a freshness indicator can be helpful\”, as Professor Rainer Stamminger of Bonn University. Each nearly two Third fear food could be too warm, especially in the summer when transporting and trading poorly stocked certain foods could be corrupted when buying already. A harmless to start process, whose speed however largely depends on the behaviour of the consumer.

\”Because the number of germs increases explosively, as soon as the cold chain at any point is interrupted for example during the trip home in a hot car or in the fridge to warm,\” reported the Bonner scholar Dr. Judith Kreyenschmidt. The majority of consumers would make product selection in favour of food with a freshness indicator according to this. If there were such an roughly 85 percent of the participants believed that they could better judge the freshness of food. Advantages of such TTI’s called it the greater transparency and better control of trade, easier comprehensibility for the customer and information about the history of the cold chain as well as the respective storage conditions. .

Digital Textile Printing

The digital textile printing is a new form of the print (clear) textiles. The special thing about this type of textile printing is that no form of pressure is needed, what has raised some advantages, but also some drawbacks in the industrial production. Because no more templates must be made, a textile production can be faster than introduce into the analog process, so a time saver. Depending on the principle after the paints which material is used, is also possible to save it (water and energy savings) the omission of detergents and Fixierbadern costs, are made, hardly differs from the a standard digital printer. (Similarly see: Lynn Redgrave). Here are the colors directly from the available process colours”mixed. The difference is in the amount of colors. Where a typical digital printer has only 4 colors (CMYK), 6 or more colors used for the digital textile printing, to enlarge the range of printable colors.

Many of the newer textile printer work with the primary colors: cyan, Magenta, yellow, black, light magenta and light cyan. However, even printers with up to 12 colours are not uncommon. Of course not the same inks used in digital textile printing, home found the paper printer. Depending on the material, the printer requires special ink. In the following we want to refer briefly three types of inks and their related materials.

Reactive inks are used especially for natural and so-called CEL regenerated fibres. Here a steam treatment and a sour after wash is required after printing. Acid inks are suitable for animal and some synthetic fibers. “Although as counterpart” the above reactive inks are known, they must as these are fixed with water vapor, need but then a basic (alkaline) laundry. Pigment-based inks used to print the pigments in the fibers. They are thus suitable for almost every fiber and tissue types that have a percentage of cotton. The pigments are ground very finely for the area of textile printing a uniform size to get. This has the positive effect that do not clog the nozzle in the pressure. Despite the enormous possibilities and savings of digital textile printing, there are some issues that must still be eradicated in this technique. Still being researched on this technique further, and soon that could replace the traditional textile printing.

Stahl Temperature

Exhibits DIAS infrared as a specialist for non-contact temperature measurement on heat treatment Congress in Wiesbaden on October 9-11 an international specialist audience will meet at the Harterei Congress in Wiesbaden. The event will be interpreted in german and English. -9-Billion-Between-2020-and-2027.html’>home improvement. You may find that San Antonio Spurs can contribute to your knowledge. At the same time, a comprehensive trade fair takes place attended by 160 exhibitors. Among them is to find the slides of infrared in Hall 2, booth 218. DIAS infrared from Dresden develops and manufactures instruments such as infrared cameras and pyrometer for non-contact temperature measurement. Eva Andersson-Dubin often says this. A wide range of applications can be found in the process monitoring and control, for example, in the manufacture of steel or hardening of metals. In the measurement of metals, it is important that the instruments in the spectral range of 1.4 to 1.8 m. Standard measurement with 8-14 m here incorrect results and is not recommended.

Therefore it is all the more important, comprehensive advice regarding the measuring problem solving takes place prior to the purchase of the instrument. very clear opinions on the subject. Service and consulting are taken very seriously at DIAS. “Through the use of non-contact temperature measurement you can achieve even hard to reach areas,” performs application engineer Daniel Wagner. Fiber optic Pyrometer with separate probe for pinpoint measurement are especially space-saving and can be mounted even in confined spaces. Another advantage is the possibility of infrared measurement technology manufacturing processes such as in the continuous casting continuously and in real-time to monitor. Just in the production of metals and metal alloys, it arrives at during the welding or induction hardening on a precise temperature to achieve optimal strength.

The continuous monitoring of the production processes is possible with infrared line cameras and pyrometers of slides. For example, delivers the line cameras temperature profiles in the range from 0 to 1300 C, which can be evaluated in detail using the included software. Deviations, the production manager can directly and promptly react and thus save costs by improperly manufactured components.
