Abstract

Small rectangular bales of alfalfa were successfully dried using two forced-air drying systems with heat from LP gas, solar energy (with off-peak electricity on some tests) or ambient air, and with average dry matter densities of alfalfa ranging from 80 to 166 kg/m³ (5.0-10.4 lb/ft³) with average moisture contents up to 37% (w.b.). The drying rates, pressure requirements for forced flow, psychrometric data, and hay quality before and after drying are reported. The data and a developed ″drying parameter″ for small rectangular alfalfa bales provide guidance for design of baled hay dryers.
