Vacuum belt dryer for fruit, vegetable and herbal extracts
Organic volatile compounds from fruits, vegetables and herbs are essential to manufacturing flavors, extracts, and pure powders. But elevating temperatures during the evaporation process risks altering their chemical structure and lowering the quality of the final product.
Gentle freeze-drying for fruit powders, herbal extracts, and flavors
The DryBand system by Bucher Merk is a dynamic belt dryer designed to dry delicate food ingredients. The material moves through an intermediate vacuum chamber between the top and bottom belt section. The drying unit has a vacuum range of 0.5 to 50 mbar and a feeding rate of up to 4,000 kg/h.
The continuous system can be configured for variable or constant drying with heating plates underneath the belt. A crushing device at the discharge end breaks the dried products into powders after drying. Meanwhile, the vapors are collected in an integrated condenser.
