Industrial lye coating line for bakery products
Streamline your bakery operations with high-speed lye coating technology that ensures consistent and high-quality pretzel and croissant finishes.

Applies Lye Coating to Bakery Products
The Belaugungsanlage ALLROUND from WP Riehle is an automated lye coating machine designed for the efficient production of a range of bakery products, including pretzels, croissants, and pastries. It features a patent-pending lye shower and dual lye curtain to ensure optimal and consistent coating results, even at high processing speeds. This machine supports continuous operations and can process up to 400 trays per hour, making it ideal for large-scale production environments.
Utilizing an adjustable conveyor speed, the ALLROUND integrates seamlessly into existing bakery production lines, offering modular extension options such as an optional salt applicator and depositor band for clean processing. Its expansive 180-liter lye tank is equipped with a heating system to maintain temperature, improving coating quality while preventing cooling. The machine’s space-efficient design includes foldable input and output tables, enhancing operational flexibility in constrained spaces.
This system suits bakeries aiming to enhance throughput and coating uniformity, featuring decentralized control with sensor alerts for low lye levels and configurable options for different baking workflows. Engineered to withstand frequent use, it provides robust performance with minimal maintenance requirements, embodying WP Riehle’s commitment to quality and efficiency in food processing technology.
