    "inventor_name": "Timothy D. Durance",
    "publication_year": 2009,
    "device_name": "nutraREV food dehydration system",
    "goal": "Rapid, energy-efficient dehydration of food and biological materials while preserving flavor, color and nutritional value.",
    "problem_addressed": "Long processing times, high energy consumption, high capital costs and batch loss risks of conventional freeze-drying.",
    "concept_summary": "The EnWave nutraREV system combines microwave heating with vacuum pressure control and continuous rotation of the product container. The open microwave waveguide evacuates the container, applies high-speed rotation, and delivers microwave energy to remove moisture quickly. The process reduces drying time to minutes, cuts energy use by about one-third and lowers capital costs by roughly one-sixth compared with freeze-drying.",
