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 fruits & vegetables
Freeze dried fruits and vegetables offer strong competition in the demanding market for healthy foods and on-the-go convenience.
Freeze-dried pet food
Freeze drying produces a shelf-stable, high quality product that retains much of the nutrition, taste, color, and shape of the original constituents, supporting pet health.
Freeze-dried bacteria cultures
Freeze drying is an idea way to preserve the viability and activity of sensitive starter cultures, probiotics, yeast, fungi and enzymes.
Freeze-dried seafood
Freeze drying can unlock new product development opportunities and add significant value to premium fish, shellfish, seaweed and algae.
Freeze-dried coffee
Freeze drying preserves the aroma, flavor and quality of concentrated coffee extract, delivering a superior product that meets the highest market expectations.
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.
