    HEAT TREATMENT OF CHOPPED ALFALFA IN ROTARY DRUM DRYERS

    Jun 16, 2010 ABSTRACT. This paper deals with the heat treatment of alfalfa chops during the high temperature dehydration process. It outlines the dryer characteristics, difficulties and potential errors in measuring temperatures in the dryer, computation techniques, the relationships between moisture and temperature during drying, and the potential effect of dehydration on the destruction of the insect

    Aug 01, 2005 (2003), the drying and fractionation of harvested chopped alfalfa in one process using a simply modified three-pass rotary drum dryer is demonstrated. Also, the aim is to dry stems and leaves to the same moisture levels of 8% (w.b.) to avoid over drying of leaves, leading to a loss in product quality. 2. Materials and methods2.1. The rotary

    Alfalfa & Innovation - Thompson Dryers | Rotary Dryer

    The whole industry of drying really took hold and expanded because of one crop: alfalfa. Around the turn of the 20th century, technology had developed enough to start drying alfalfa. This had many benefits – increased shelf life, increased protein content life, ease & lower cost of shipping, handling, and feeding. However, alfalfa is a … Continue reading Alfalfa & Innovation

    May 01, 2006 High-temperature drying is typically done in rotary drum dryers, where air temperatures are maintained in the range 200–800 C (392–1500 F) at the inlet to 60–95 C (140–210 F) at the outlet (Sokhansanj et al., 1998). During drying, various volatile organic compounds (VOCs) are generated in the form of smoke, odour and particulate
