Assessment Of The Effects Of Airflow Conditions Related To Hop Drying, David Mabie

Department of Biological Systems Engineering: Dissertations and Theses

Hops have been utilized by brewers for centuries to contribute bitterness, antimicrobial preservation and desirable aromatic profiles to beer. The hop cone is a small, lightweight, high moisture content flower which produces lupulin glands containing resins and essential oils that contribute desirable characteristics to beer. Due to the high harvest moisture content (75% wet basis), hops must be rapidly dried to properly preserve them for future processing and brewing. While hops have been dried for centuries, most literature from the past century has focused on drying to minimizing loss to the resin or physical cone structure. The objectives of this …
