Stack Chips

Pile of chips is the name given to a kind of (potato) chips that are mechanically formed so that they pile up easily. They are sold in a cardboard or plastic cylinder.

Development
The first and most famous brand stacking chips Pringles, which were first sold in 1968. Procter & Gamble was looking for a way to improve their chips after customers complained about broken and stale chips and that too much air in the bag would be. Chemist Fredric Baur invented the form which further improved by Alexander Liepa and patented. Gene Wolfe developed the machine to make the stack of chips.

Production
While traditional chips are made ​​from whole potatoes are stacking chips as example Wokkel of mashed potatoes or potato flour made. This powder is pressed into a special shape (in the case of Pringles a hyperbolic paraboloid ), and then deep-fried, seasoned, and placed in a cylinder. The advantage of this procedure is that all of the chips have an identical shape so that they can be stacked more compact in the bus. Another advantage is that the quality is less dependent on the quality and the shape of the potatoes and thus is constant. Because the moisture for frying is already largely disappeared from the mashed potato mixture, frying shorter, which both saves energy and provides a lower fat content in the final product.
