DryBand

Product catalog summary

Overview: The Bucher DryBand is a belt dryer designed for continuous vacuum or freeze drying of various products such as malt, drink or soup ingredients, and pre-dried or frozen fruit, vegetable, or meat pieces. It offers continuous and gentle product drying with minimal oxidation and flavor loss, adjustable temperature profiles, low energy consumption, and fully automated operation and cleaning.

Application: The Bucher DryBand is suitable for drying liquid and free-flowing powders and other heat-sensitive products under vacuum. It is also effective for freeze drying applications, including coffee and meat pieces.

Design and Functionality: The dryer is particularly suitable for products that pass through a glutinous or highly viscous phase during drying and are sensitive to mechanical stress. Liquid products are distributed on belts with swivel feeders, while powders and larger products are conveyed into a hopper. The product is fed into an intermediate vacuum chamber and loaded onto the top belt by a rotary dosing system. Heating plates under the belts allow for constant or variable drying rates, and the last zone can be a cooling zone if needed. Dried products are cut to size and discharged into the atmosphere with alternating pressures, with vapors recovered in a condenser.

Technical Data:

Feeding rate: Variable
Heating & cooling surface: 0.2 to 325 m²
Heating range: 20 to 180 °C
Electrical installed power: 2 to 40 kW
Vacuum range: 1 to 50 mbar
