Fitting for today’s day of the bratwurst: Welcome to our summer series “bratwurst” in Application Engineering III.
Facts about the Bratwurst Part 3. Our application technology explains technical facts.
Have you ever wondered why bratwursts usually burst open lengthwise on the grill?
Besides the casing, a bratwurst consists of a mixture of meat, fat and spices. When the sausage is heated on the grill, the fat it contains melts and becomes liquid. The liquid fat takes up more volume than before. In addition, the water contained in the meat becomes water vapor and expands in the process. The expansion of fat and water causes a pressure increase inside the sausage. This pressure increase generates stresses in the sausage skin. Since the circumferential stress in a thin-walled cylinder loaded by internal pressure (which is the shape of a typical bratwurst) is twice as high as the longitudinal stress, the sausage on your grill will burst open longitudinally. Interesting, isn’t it?
Of course, we can calculate not only the tension in a sausage skin, but also that in, for example, a textile of a boat fabric. For this purpose, our experts from the application technology department are at your disposal with help and advice.
Welcome to our summer series “bratwurst” in Application Engineering I.
What application technology has to do with bratwursts, we explain to you over the next few weeks.
Our application engineers are not only familiar with technical textiles, they are also real experts on all aspects of barbecueing. That’s why we are starting today with facts about the sausage, just in time for the barbecue season.
Did you know that the weight of the polyester fabric used in one square meter of Heytex Torware H2599-1E is approximately equal to the weight of 4 bratwursts?
The total length of yarn in one square meter of Heytex door material HEYdoor H2599-1E is even equal to the length of 35,200 bratwursts strung together.
