Vacuum Belt Dryer


The hegatec Continuous Vacuum Belt Dryer is used for gentle drying of pasty and liquid products like malt mixes, meat extracts, herbal extracts etc. The hegatec Vacuum Belt Dryer is available from laboratory size to industrial size. Based on precise calculations your hegatec Vacuum Belt Dryer is customized for your product needs.


The process starts with mixing the liquid or pasty product in the hegatec Feeding Vessel. The feeding pump ensures a uniform distribution on the conveyor belt inside the dryer. The housing of the hegatec Vacuum Belt Dryer is under vacuum. The operating vacuum is precisely controlled by the hegatec Vacuum System. After feeding the product on parallel operating conveyor belts, it is conveyed through different heating zones and a final cooling zone. The integrated hegatec Inline Granulator mills the final product. The required dry matter of the final product can be regulated by adjustable parameters such as feeding volume, conveying velocity, temperature and pressure.
