MICROWAVE DRYING
FOOD AND MATERIAL
HOW DOES IT WORK?
tHE SCIENCE OF MICROWAVE DRYING
Microwave drying is a dielectric process that converts electromagnetic energy into heat within the product (volumetric heating), leading to water evaporation. Microwaves are generated from electric energy, and directed to material (food or industrial material) in a chamber. Polar molecules in the material absorb the microwaves and try to align their electric field, causing rapid vibration and friction between molecules. This friction converts microwave energy into thermal energy, increasing the temperature of the material.
HOW DOES IT COMPARE?
LEVERAGE MICROWAVEs
Unlike other heat sources, microwaves heat volumetrically by penetrating deep into the material to heat the whole volume simultaneously. Microwave’s volumetric drying speeds up an otherwise slow process, all while optimizing energy efficiency and improving final product quality. Read our blog post to learn how it compares to a traditional system.
Combining the advantages of microwaves with NuWave Research’s patented techniques allows our equipment to reach high throughputs with capacities from 100kg per hour up to +40 ton per hour and achieve uniform product drying through even energy distribution.
