Vacuum-microwave dryer

Offering main image Contact : Institute of Agricultural Engineering Contact to: Adam Figiel (adam.figiel@upwr.edu.pl). Year of purchase : 2022, equipment ID : 100, type : Prototype Promis-Tech Wroclaw. This type of dryer allows rapid removal of water from the raw material thanks to internal microwave heating, which creates a high pressure gradient between the interior of the material and the surrounding vacuum, which favors the diffusion of moisture. This is accompanied by a puffing effect, which limits the collapse of the cell structure and leads to a crispy texture of the dried product with a high bioactive potential thanks to the short drying time and limited presence of oxygen.
