Home / How Haygain steamers work

Haygain's unique hay purifying method propels steam from a best-in-class steam generator through a patented spike manifold system to thoroughly purify all the hay in the purpose built steam chest.

Haygain steamers purify hay from the inside out

Haygain's manifold system

The five-spiked manifolds found in every Haygain steamer

Purpose-built steam chest

The thermally efficient steam chest maintains the steam volume and high temperature to ensure that the respirable particles, fungal spores, bacteria and mites in the hay are eliminated. This ensures the hay is cleaner, more palatable and maintains its nutritional value.

Unique spike manifold design

The patented configuration of the manifolds pushes steam into the hay, distributing it evenly throughout the unit and allowing temperatures in excess of 212ºF to be reached. The aluminum plates, which hold the spikes, accumulate more heat under the bale to assist with raising the temperature inside the hay chest, optimising its efficiency. Perforated spikes force steam from the centre of the hay outwards, ensuring total steam absorption.

The result is clean, highly palatable hay that horses will love to eat and is 99% free from bacteria, fungi, and mold spores; helping to manage and prevent respiratory disease.


Purifying your hay in 5 simple steps:

Use funnel and watering can provided to fill the Steam Generator until water is visible in the Filler Spout.

Place a bale or loose hay over the Steam Manifolds and push down firmly so Manifold Spikes pierce the hay to their full length. Lower lid and fasten catches.

Push down the green On/Off Button located on top of the Steam Generator.

Allow the hay to steam for 60 minutes and check the thermometer needle is in the green zone (if not continue until it is).

Switch ‘off’ by pressing the green On/Off Button. Undo the catches and open the hay chest lid. Caution: steam is hot. Remove the hay and feed immediately or within 24 hours.

Cleaning and maintenance

It is necessary to rinse the steam generator regularly and de-scale it once a month, or at least once every two months.

The frequency of de-scaling required is dependent on how hard the water is in your area and how often you use your Haygain steamer.

The hay container should be kept clear of hay and haylage debris and washed out regularly.
