Lye application system for pretzel production
In high-volume pretzel production, achieving consistent lye application can be challenging. Traditional methods may result in irregular coatings, impacting the final product’s texture and appearance.

Ensures uniform lye application at high speeds
The ALLROUND by WP Riehle is a highly efficient lye application system designed for optimal results in pretzel production. Featuring a patented lye shower and double lye curtain, it guarantees uniform lye distribution even at high production speeds. The system includes an extendible 180-litre lye tank with adjustable heating to maintain consistent lye temperature. Optional features like a salter with interchangeable containers allow for quick changes between different toppings, and an unloading belt prevents dough deformation by minimizing drop height. Capable of handling up to 400 trays per hour, the ALLROUND system is ideal for automated pretzel manufacturing processes.
