Mais ces chips se brisent facilement.<\/p>\n<\/div>\n<p>Comment est-il possible de manipuler en toute s\u00e9curit\u00e9 des aliments fragiles tels que les chips dans des usines automatiques? Le remplissage d'un paquet \u00e0 grande vitesse sans cr\u00e9er un tas de miettes est un d\u00e9fi que la technologie spatiale a aid\u00e9 \u00e0 relever.<\/p>\n<p>Une entreprise allemande sp\u00e9cialis\u00e9e dans les emballages alimentaires, qui cherchait une nouvelle m\u00e9thode pour conditionner des chips dans des sachets sans les casser, a sollicit\u00e9 l'aide du programme de transfert de technologies de l'ESA.<\/p>\n<p>Il s'est r\u00e9v\u00e9l\u00e9 que d'une certaine fa\u00e7on, la chute d'une rondelle de pomme de terre dans un sac est comparable \u00e0 l'atterrissage d'un engin spatial sur une autre plan\u00e8te. La vitesse de descente, les conditions atmosph\u00e9riques et le d\u00e9bit d'air d\u00e9terminent la s\u00e9curit\u00e9 de l'atterrissage.<\/p>\n<p>En \u00e9tudiant le comportement des chips pendant leur chute, les partenaires de transfert technologique ont pu concevoir un nouveau syst\u00e8me de mise en sac alimentaire qui s'est int\u00e9gr\u00e9 dans une machine d'emballage de haute technologie.<\/p>\n<p>Cette machine peut g\u00e9rer tous les aliments l\u00e9gers de forme complexe 30 \u00e0 50% plus vite que les \u00e9quipements pr\u00e9c\u00e9dents. Malgr\u00e9 sa haute vitesse de fonctionnement, les atterrissages en douceur permettent de r\u00e9duire au minimum les brisures.<\/p>\n<p>Les profits se sont envol\u00e9s avec la descente des chips \u2013 dans les sacs! Maintenant, la nouvelle machine de l'\u00e8re spatiale est disponible dans le monde entier.<\/p>","protected":false},"excerpt":{"rendered":"<p>Crunchy crisps are one of the most popular snacks.
