HAYGAIN hay steamers... expertise beyond engineering


The unique Haygain method introduces a recently-patented, laboratory-proven manifold system, designed to introduce steam into the hay in the most effective manner.  The manifold is housed in a fully insulated container, incorporating a purpose-built steam generator, all components having been designed and manufactured by Haygain.


Steam is released from the steam generator into a multi-layer construction hose via an elbow, specifically designed to create a small amount of back pressure (75-100mb); as illustrated in the Haygain HG-2000 model (right), the steam is forced into and completely through the fully strung bale via the five-spiked manifolds.


Carefully-controlled laboratory studies into the dynamics of steam and temperature distribution (in both baled and loose hay) resulted in the specifically adapted deltoid configuration of the manifold.


Steam is introduced into the forage through the perforated spikes and distributed throughout the forage mass and as this takes place, the temperature within the unit is raised to a level sufficient to destroy fungal spores and bacteria.


Meanwhile, the aluminium plates holding the spikes themselves accumulate heat, which in turn contributes to the high temperature within the Haygain unit, contributing to the overall efficiency of the system.


The insulated Haygain unit traps the steam until the container is completely filled, raising and maintaining the necessary high temperatures to kill fungal spores and bacteria found in forage.
