Producing Berliners and donuts

Produce delicious doughnuts with fat baking appliances from WP Riehle

What does the perfect Berliner and donut taste like?

There are no limits to creativity when it comes to the taste and visual design of Berliners and donuts. Exotic fillings, alternative doughs (vegan or gluten-free) and unusual toppings are all the rage. Despite countless variations, one demand is always the same: best taste with low fat content.



In the production of Berliners and donuts, the shape plays a key role. Traditional Donuts and Berliners should be perfectly round with a slightly curved surface.


A particularly fine porosity and smooth surface structure also distinguish the quality of Berliners and donuts.

Fat content

The right amount of fat is crucial when it comes to freshness and taste – good if you can control the fat intake.

All our deep fryers have digital temperature control. It guarantees precise temperature control.
We have deliberately selected to use heating coils immersed in the fat, as the advantages simply outweigh the disadvantages. The temperature can be kept more constant and corrected more quickly. The fat absorption by the products is thus kept to a necessary minimum.
Sediments accumulate underneath the heating coils and thus burn much less than with panel heating.

From Linie 2000 onwards, all machines also feature cycled heating, which prevents fat burning on the heating coils.

Feedback on the deep fryers:

Press article in the Austrian Bakers & Confectioners Newspaper

The carnival season begins in November and with it the doughnut season (Berliner season). In October 2023, the „Österreichische Bäcker & Konditor Zeitung“ (Austrian Bakers & Confectioners Newspaper) therefore published an article focussing on doughnut baking. Our L2000E deep fryer was presented here as a particularly energy-saving appliance.
