Freeze dryers and continuous freeze belt dryers
The Bucher Merk Zeodration System uses zeolite reactors to remove water by adsorption. Zeolite, a crystalline clay with a pore size of 4 angstroms, specifically retains water molecules. The selective process ensures that volatile aromatic substances remain in the product as far as possible, resulting in minimal loss of aroma. The low partial pressure during water adsorption achieves a high level of efficiency without compromising the quality of the end product.
A major advantage of the Zeodration system is the combination with vacuum dryers. Both batch and continuous drying processes can be carried out, which enables flexible production. Thanks to the regeneration of the zeolite, the full adsorption capacity is retained, ensuring consistently high product quality. The system shows its strengths particularly in the pressure range of 0.5-5 mbar and offers reliable and gentle drying.
The zeodration systems can be easily combined with Bucher vacuum drying ovens and vacuum belt dryers. Existing systems can be retrofitted to take advantage of zeolite technology. Different dryer sizes are available depending on requirements, with adsorption capacities of 1 to 1000 kg/h of water and heating surfaces of between 0.2 and 325 m², for optimum adaptation to production requirements.

Our machines and systems for freeze drying
DryBand Lyo
The DryBand Lyo belt dryer from Bucher Merk enables the continuous freeze-drying of heat-sensitive products such as coffee, fruit, vegetables or pieces of meat, ensuring maximum product quality through gentle drying.
Bucher Merk DryCab
The Bucher Merk DryCab vacuum drying oven is specially designed for drying heat-sensitive products in the food and pharmaceutical industries and uses a vacuum system to enable gentle drying at low temperatures, thereby maintaining maximum product quality, while several rectangular, horizontally arranged heating plates ensure efficient drying.
Bucher Zeodration
The Bucher Merk Zeodration System uses zeolite reactors to efficiently remove water or solvents by adsorption, with the selective pore size of 4 Angstroms retaining only water molecules, allowing a reduction in volatile molecule loss and flavor retention; in combination with batch or continuous vacuum dryers, the system provides better product quality than conventional freeze dryers, maintaining adsorption capacity through cyclic regeneration of the zeolites, and existing plants can be upgraded with the zeodration system to achieve optimal flavor results.
Food that you can freeze-dry
Fruits
Drying frozen fruit by freeze-drying is a particularly gentle method of preserving it. Volatile flavors are also optimally preserved.
Coffee and tea
Freeze dryers and continuous freeze belt dryers are perfect for freeze drying coffee and tea extracts.
Vegetables
Freeze-dried vegetables are ideal for instant products such as soups, as they can be quickly remoistened. Freeze-drying preserves volatile flavors even better, which further increases product quality.
Pet food
Freeze-dried meat cuts and animal feed are characterized by their long shelf life due to their low water content. Compared to conventional drying processes, volatile aromas are better preserved
Fish and seafood
Freeze-drying fish and seafood preserves volatile flavors much better than conventional drying methods.
Meat
Freeze-dried pieces of meat or minced meat offer excellent long-term storage and are perfect for use in ready meals or as animal feed.
