Decades of experience freeze drying a wide range of applications
The first RAY® freeze drying plant was installed in 1955, so we really can say that we have focused many decades of expertise developing state-of-the-art freeze drying technologies so that our customers can innovate and push boundaries. And it’s not all about ready meals, fruit, coffee and petfood. We’ve carried out more than 3000 tests and worked with about 1000 product types. Supported by RAY® freeze drying technology and GEA expertise, manufacturers around the world are moving into bold new markets, from candy to paint.
A wealth of freeze drying opportunities
Freeze drying is a proven food preservation technology that presents many opportunities for creating new products that meet growing markets and expectations for healthy, sustainable foods and ingredients.
Freeze drying is really versatile, and can be used to process a wide range of food types, from coffee and herbs, to dietary supplements and ready meals, so you can think creatively and develop new concepts.
Freeze-dried candy
Freeze drying preserves the candy’s original shape and flavor, while transforming its texture from chewy or sticky to light and crunchy.
Freeze-dried dairy products
Freeze-drying can convert yogurt, cheese and cream into light, rehydratable pieces or powders that have a long shelf life without refrigeration
Industrial freeze dryers for more sustainable food manufacturing
Freeze dried products also require no refrigeration for long term storage or long distance transport, which not only helps to reduce waste, but can offer up all sorts of potential for new export markets, as well as simplifying transport logistics for local and national markets. For food producers, freeze drying offers up new prospects for creating additional value from perishable fresh foods, for preserving surplus crops and “wonky foods” and preventing waste. So as well as setting the stage for product innovation and generating new revenue streams, freeze drying helps to support a greener future both for you and for your customers.
Why freeze drying?
Key benefits of freeze drying:
- Supports maximum retention of nutrition, taste and aroma, color, shape and texture
- Creates a product that can be rehydrated with water for simple, fast preparation
- Maintains product stability for a long shelf life at ambient temperatures
- Preserves perishable or surplus foods to reduce food waste
- Reduces or completely cuts the need for cold chain distribution, which reduces carbon footprint
- Preserves products with low weight and easy handling, which cuts shipping costs.

La biotecnologia a confronto con la realtà
Il nuovo Application and Technology Center (ATC) di GEA a Sarstedt, a sud di Hannover, non è né uno showroom né un laboratorio. È un luogo dedicato a test, raccolta dati e decisioni preliminari. È qui che si capisce se un concetto biologico può diventare un processo industriale solido. Si tratta di un passo più importante di quanto possa sembrare.
Cambiamenti nel settore del confezionamento alimentare: 4 tendenze
La termoformatura riveste da tempo un ruolo centrale nel settore del confezionamento alimentare. Ora si trova di fronte a un cambiamento radicale. Con l'inasprirsi delle normative, l'evoluzione dei materiali e l'aumento dei costi, le linee di formatura, riempimento e sigillatura non devono solo funzionare in modo affidabile: oggi hanno un ruolo fondamentale nel garantire che gli alimenti rimangano freschi, convenienti e riciclabili. Ecco le principali tendenze nella termoformatura che stanno plasmando il confezionamento e la consegna di prodotti alimentari.
