CompanyRadiant Energy Vacuum (“REV”) Dehydration Technology
Vancouver-based industrial technology company, UBC spin-off
Proprietary method of drying food, bulk liquids, biological and pharmaceutical materials

MethodRadiant Energy Vacuum (“REV”)
Microwave energy under vacuum enables high-speed, low temperature drying above or below freezing point
Preserve nutritional value, bioactivity, flavor, color, texture better than high temperature methods such as spray or air drying
Target to replace conventional drying for sensitive materials and enable new dry products
![Page 4: REV Dehydration: Commercial Drying Technology for Foods and Food Ingredients.](https://reader038.fdocuments.in/reader038/viewer/2022102611/56649ccc5503460f94996b04/html5/thumbnails/4.jpg)
REV TechnologyTechnology Overview
REV technology applies microwave energy under vacuum for high-speed drying at low temperatures
Key discoveries:
1. Methods of distributing a microwave field to avoid plasma discharge in vacuum.
2. Means of achieving reliable, homogeneous dehydration across a large load.
3. Continuous processing.

REV TechnologyTargeted Advantages
Faster Dry in minutes or hours versus days, for reduced capital costs
Continuous Reduces labour & energy, easily automated
Better
Most economical way to dry temperature sensitive products and retain quality, such as biological activity, nutrients, colour, solubility, etc.

Puffing
Steam & air bubbles inside material can expand & create puffed structure.
If material is dehydrated until rigid, expansion will be retained
Example: flour & water dough balls.
