SOIL PASTEURIZATION

   HOW IT WORKS

The Steam 'N Air is the combination of three separate portable components: the steam generator (SG12 or SG15), aeration blower (AB28), and the optional Tow 'N Dump Soil Aeration Cart.  These three components work together to perform the task of pasteurizing potting soil and other materials

 

Each portable unit is a separate component. Customers may choose to buy more than one soil aeration wagon to streamline their operation. For example - some customers prefer to load flats from one wagon while the other wagon is in the pasteurization cycle..

 

In the pasteurization steam cycle, the Steam Generator raises the temperature of 2 cubic yards of material to 170°F for 2 1/2 hours.  The AB28 Blower assists with enough air flow for 28" of material when material is placed in an aeration bin or cart.  In the cool down cycle, the AB28 Blower will dry the material to the moisture saturation level that existed before the steam cycle.

The Siebring Steam 'N Air Soil Pasteurization System is an innovation from a company that leads the way in products that are beneficial to the greenhouse industry.

 

Soil pasteurization offers an effective alternative for growers that previously used methyl bromide.  Methyl bromide use was banned completely in 2005.
