Perfect lye application
for pretzels and pretzel products

Lye application concepts

Perfekte Brezeln

Germany and the pretzel equator

It is hard to imagine southern Germany without pretzels or pretzel products in general, which are an integral part of the breakfast table there. In the centre of Germany, the pretzel equator runs through the country – while pretzel products are an established feature in the south, interest in refined pastries is also growing in the north.

The perfect pretzel cannot really be defined, since the regional differences in shape and taste are too big.



The shape of the pretzels usually differs somewhat from bakery to bakery, depending on whether they are shaped by machine or by hand. However, the typical shape featuring the thickened bottom and ‘folded arms’ are instantly recognisable.


No matter whether soft or crispy, the inside of the pretzel should always be finely pored and loose.

The lye

The perfect lye finish not only depends on the way the lye is applied, but also on the right choice of lye.


Economical solutions for every production size

The focus varies depending on the bakery and production size. 
With our solutions we offer support for every size of business and production. It means you receive equipment that is tailored to your needs and provides you with perfect support and relief in your everyday work.
At the centre of each of our solutions is the claim to deliver consistent quality that is also correspondingly easy to reproduce.

We are still successfully setting the standard in the field of lye application. We were the first manufacturer to introduce the double lye curtain, which we have successfully supplemented with the patented lye shower. The result is complete coverage of the dough, even at high speed.
