1 REV Dehydration: Commercial Drying Technology for Foods and Food Ingredients

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

3 Method Radiant 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

4 REV Technology Technology 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.

5 REV Technology Targeted 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.

6 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.
