Pilot plant freeze dryer for sensitive products
Manufacturing food products like instant coffee, vegetables, and sensitive items such as enzymes and lactic acid bacteria requires precise drying methods. Maintaining the natural properties, nutrients, and colors during drying poses significant challenges in these processes.

Ensures uniform drying with short batch times.
The RAY® Pilot Plant (RAY® PP) from GEA is a batch-based freeze dryer designed to handle a variety of food and sensitive products. It processes items under vacuum to preserve their natural properties and nutrients. Once loaded, the drying process is fully automated and monitored through a touchscreen interface. The RAY® PP manages pressures as low as 0.1 mbar and ensures short downtimes with rapid evacuation and deicing. The system can determine the end point of drying based on key factors like temperature and weight changes. Available in RAY® PP 1 and RAY® PP 2 sizes, the freeze dryer accommodates different production needs, making it suitable for both small-scale and larger batch processing. This efficient freeze dryer is ideal for food industries and other sectors requiring precise preservation.
