Automated pretzel lye application system

Enhance your bakery’s output with high-efficiency lye application, achieving consistent, high-quality pretzel and pastry finishes with minimal labor, seamless integration, and precise control across production variations.

Applies Lye Coating for Bakery Products

The Belaugungsautomat Comjet from WP Riehle is engineered to optimize the lye application process in bakery and pastry production, offering unmatched efficiency and precision. Utilizing a patented lye shower system with two additional lye curtains, it ensures consistent and even coverage, regardless of production speed. Ideal for pretzels, lye rolls, and lye-dipped croissants, the Comjet processes up to 300 trays per hour, integrating into continuous, fully automated lines. Operated via a robust glass-touch panel, it features a variable-speed conveyor for adaptable production needs. The lye tank, available in 180 or 250 liters, includes a heating system to maintain optimal temperature, enhancing lye reactions. Optional integration with a WP Scoring Robot further increases automation by delivering precise cuts post-coating. Designed for food and snack production, it supports seamless integration with upstream dough loaders and downstream cooling and packing stations. For environments requiring robust performance, the Comjet reduces labor and increases throughput while maintaining high-quality lye application with minimal maintenance downtime.
