GEA’s RAY™ Pilot Plant (RAY™ PP) is a batch-based freeze dryer designed to process general food products such as instant coffee, fruit, vegetables, meat, seafood and pet food, as well as very sensitive products such as lactic acid bacteria, enzymes and lactoferrin.
Today’s consumers actively seek out food products that are easy to prepare, tasty and stay fresh for longer. Freeze drying enables manufacturers to meet these demands by preserving the natural color, properties and consistency of the product, as well as its constituent proteins and vitamins.
Offering substantial benefits to nearly every area of food processing, including fish, fruit and herbs, RAY™ freeze drying technology provides a high quality solution. Frozen products are dried under vacuum, ensuring that the inherent solvents in the product are removed as vapor.
Operated via a touchscreen, the RAY™ PP is designed for hygienic processing and, as such, is easy to clean and maintain. Once product has been placed in the chamber, the process runs fully automatically and all vital parameters — product temperature, heating profile, loss of weight, etc. — are monitored and stored to provide full documentation and ensure repeatability. The RAY™ PP is able to automatically generate drying profiles and, based on maximum product temperature and/or factors such as constant weight, temperature and vacuum difference, determine the end point of the process.
Although designed to operate at 0.2 mbar, the RAY™ PP can tolerate pressures as low as 0.1 mbar. In addition, the RAY™ concept ensures short downtimes between batches, based on rapid evacuation times, effective deicing and efficient tray loading. The pilot plant comes in two sizes:
|RAY™ PP||RAY™ PP 1||RAY™ PP 2|
|Drying surface (m²)||0.7||1.5|
|Dry matter (%)||20.0||20.0|
|Expected batch time (h)||8.0||8.0|
|Sublimation (kg H2O/day)||15.3||30|
|Installed power (Kw)||12||25|
|Average consumption (Kwh/h)||7||12|
|Water consumption (L/h)||50||75|
