Continuous freeze drying solution for coffee and food pieces
When processing heat-sensitive products such as coffee, fruits, vegetables, or meat, maintaining product quality during drying is essential. Traditional drying methods often lead to oxidation, flavor loss, and higher energy costs, which can be problematic for maintaining clean labels and product integrity.
Gently dries products with minimal flavor loss
The DryBand Lyo by Bucher Unipektin is a belt dryer designed for the continuous freeze-drying (lyophilisation) of pre-dried or frozen food pieces, as well as coffee. It handles free-flowing granular products, maintaining high product quality through non-oxidizing, low-energy drying. This system involves a series of belts that convey products in a controlled environment, using independent heating zones and patented radiant plates to optimize drying rates. Feeding rates range from 2 to 4000 kg/h, with heating and cooling surfaces from 0.2 to 325 m², and a heating range of 20 to 180 °C. The vacuum levels vary from 0.5 to 50 mbar, ensuring gentle, efficient product handling. Its closed system design ensures automated operation and cleaning, making it suitable for industries like coffee/tea, fruits and vegetables, meat or seafood, pharmaceuticals, probiotics, enzymes, and infant nutrition.
