How it came about
Councillor Peter Garnham President of Maitland Steam & Antique Machinery Association attended the 200 years celebration of the founding of the city of Bathurst. At the event they gave away to the public corn on the cob it was cooked in a wood fired tub the corn was served with butter pepper and salt.
Peter suggested at the Steamfest steering committee meeting that the committee should look at serving corn on the cob at the Steamfest Festival 2016. Better still if we could use steam to heat the cooking vessel

The Steam heated Corn Cooker
The concept of using steam to heat a vessel that the corn was to be cooked in was discussed at the next meeting of Maitland Steam & Antique Machinery Association. One of our members had a 150 Gallon Stainless steel refrigerated milk cooling vat that he felt would do the job and donated it to the club.
The refrigeration pipe work was removed and the dimple plate heat exchanger that forms the curved bottom of the vessel was pipe up to have steam connected to it.
Steam at 40 PSI from a Portable Steam Engine will be feed to the cookers steam distribution manifold via a high pressure flexible steam hose.
The temperature of the water will be controlled by a manual control / isolation valve there is a pressure gauge after the isolation valve to indicate the pressure within the heat exchanger and a dial thermometer to indicate cooking temperature mounted on / in the vessel. The heat exchanger is split into two circuits the steam will exit the heat exchanger via two stem traps and non-return valves this will allow the condensate (condensed steam to be feed back to the boiler feed water tank for re use as feed water for the Portable Steam Engines boiler.
