|Unique method enables steam to penetrate the center of the bale and diffuse outwards, ensuring even steaming throughout. The unit is thermally insulated and sealed to maintain the high temperatures (in excess of 212 degrees F) critical to killing all harmful fungal spores and bacteria (and other living organisms such as mites), effectively sterilizing while maintaining the hay's nutritional value, resulting in a totally dust and spore-free palatable forage. Fill up the independent steam boilers with tap water, which rapidly generate steam. Place a fully strung bale onto the manifold spikes within the HAYGAIN steam chest. Steam travels through these unique aluminum pressure die cast steam distribution manifolds and infuses the bale, ensuring total absorption throughout the bale. A steam cycle takes approximately 60 minutes, and the treated hay is immediately ready to feed as required. For a second bale, since the boilers now are preheated, the cycle time is reduced to approximately 30 minutes. Full bale unit requires 30 amp, 120 volt circuit.
