Since the first Potato Chips fryer was designed in the early 1970s by PPM AB (today known as Rosenqvists Food Technologies), the potato itself has always been kept in focus. We have designed all our machines, from potato intake to the fryer outlet, with the potato in mind. 

Over the years, this approach has strengthened our knowledge of the potato as a raw material and how to best treat from the first step of the process, to the finished product. 

When designing equipment, we combine knowledge and experience with the latest computer simulation programs to design and manufacture efficient and reliable equipment for the process of producing potato chips, as well as frozen potato products and other snack food. 

Thermal treatment

The core of the Rosenqvists’ food processing know-how is thermal treatment or in other words the ability to blanch, dry and fry raw materials. The range includes the unique design for frying systems, designed to add customer value by accurate temperature control and an even product flow over the full fryer width. This is possible by using several internal inlets and outlets combined with temperature sensor feedback. All of Rosenqvist’s fryers has a short oil turn over time, which is achieved by the low oil volume in the system. The frying oil is cleaned from debris in a continuous full flow oil filtration, making the used oil usable again, which creates a cost-efficient solution since we take good care of the oil.  

Thanks to the founders of PPM AB (Jan Bengtsson, Roland Haraldsson, Bo Jönsson and Claes Friberg) and several other innovators over the years, we can offer well-proven processing equipment. The current management team at Rosenqvists Food Technologies carries on the legacy of PPM AB and is determined to continue to improve our offer to producers of potato chips, snacks and frozen potato products.
