In addition to actual plant delivery, GEA Niro has the experience and market know-how to support you in your product research and feasibility studies. The Atlas RAY™ concept is the result of many years of plant and process development based on the research and collaboration with our customers in all parts of the world. The result is a freeze drying process – as shown in the diagram – that is second to none.

Featuring 2 x RAY™ 125
1. Tunnel freezing/frost storage
One 8 hour preparation shift provides sufficient product for 24 hours of freeze drying. Freezing is by the first in/first out principle.

2. Transport by overhead rail
Trolleys carry the product trays from the freezing, through freeze drying to emptying. A simple, hygienic, and safe system.

3. RAY™ freeze dryer
Fully automatic control of the drying cycle for each batch. Just close the door and press the button.

4. Heat supply system
Drying is carefully controlled throughout the temperate range – from below freezing temperature (brine) or room temperature (cooling water) up to 130̊ C – to ensure perfect product quality.

5. Vacuum system
Process vacuum is achieved in less than eight minutes

6. De-Icing
Type CDI

7. Refrigeration system
Incorporates highly efficient refrigeration compressors with automatic capacity control

8. PC/PLC control system
The control system ensures optimal operating conditions throughout the plant – freezing, drying and associated heating, vacuum and refrigeration systems. Remote control via modem supplied as option.
