ZIRBUS Sublimator EKS-R Food Freeze Dryers

ZIRBUS technology GmbH is a German manufacturer of autoclaves, sterilisers and freeze dryers based in Bad Grund in the Harz region, with experience since 1984 and over 50 employees. It builds customised equipment from single laboratory units to complete plants for the food, pharmaceutical and research sectors, helping producers dry heat-sensitive products while keeping colour, aroma and nutrients.

For food, the Sublimator EKS-R series freeze-dries bulk materials such as fruit, berries, truffles and herbs, and is also used for animal feed. The R stands for radiation: water-flooded shelves heat suspended trays by radiant heat without direct contact, giving uniform temperature distribution and faster drying thanks to the larger exposed surface. Standard units range from 15 to 500 kg of ice condenser capacity, with custom designs up to 1,200 kg, an ice condenser at -45 C and shelf temperatures up to 110 C. Products are loaded in GN containers or aluminium bakery trays, and laboratory and pilot freeze dryers support recipe development before scale-up.

• Sublimator EKS-R series: bulk food freeze dryers in standard sizes 10, 30, 50, 100, 150 and 300.
• Radiant shelf heating: water-flooded shelves heat suspended trays without contact.
• Process range: ice condenser at -45 C and shelf temperatures up to 110 C.
• Flexible loading: GN containers or aluminium bakery trays for fruit, berries, herbs and truffles.
• Pilot and laboratory units: development freeze dryers that scale up to production systems.
• Custom engineering: plants made in Germany to customer specifications and 100% recyclable.

• Fruit exporters producing freeze-dried durian, jackfruit or strawberry snacks for Asian and European markets.
• Herb, ginseng and medicinal plant producers preserving active compounds by low-temperature drying.
• Pet food makers producing freeze-dried meat or fish treats.

• Gentle drying: freeze-drying under vacuum keeps the shape, colour and aroma of fruit, berries and herbs.
• Uniform results: radiant heating of suspended trays avoids hot spots from direct contact.
• Scalable capacity: standard units from 15 to 500 kg ice capacity, with custom plants up to 1,200 kg.
• Lower development risk: laboratory and pilot freeze dryers allow recipe trials before investing in production units.

Freeze-dried fruit snacks, instant ingredients, herbs and pet treats are growing as consumers want lightweight, shelf-stable products without additives. Vietnam's tropical fruit sector, including jackfruit, mango, durian, strawberry and dragon fruit, increasingly turns to freeze-drying to add value and reduce post-harvest losses for export.

ZIRBUS technology GmbH is located at Hilfe Gottes 1, Bad Grund (Harz), Germany, operates since 1984 and has over 50 employees. Besides freeze dryers it builds laboratory and production autoclaves, pure steam generators and vacuum dryers, and works with international business partners.
