[Syrupmakers] Steam Kettle Conversion

[Richard Harrison]

I've never heard of anyone doing syrup like this. You may be breaking new ground. Frankly, I think it may be a better way. It may even reduce cooking time a little. Please keep us abreast of your "experiment". It sounds very interesting!                Richard Harrison
  I suggest that you contact Dr Bill Outlaw about your project. He has the website SouthernMatters. He is steeped in technical knowledge--of a lot of things.     From: sgardipee <sgardipee at hot.rr.com>

GlenFood grade Thermal Fluid  (Globaltherm -TM) is stable from (-4 degrees F to 618 degrees F). When processing sorghum juice, it is simmered until it reaches between 226 degrees-F  and 230 degrees-F.or when it reaches a density of 78 degrees to 80 degrees Brix with a syrup hydrometer.I do not want to use water or steam as my research seems to show “hot oil” is more efficient and easier to control. The cooking industry is looking more and  more at hot oil kettles over steam kettles,also the steam is under pressure as in a pressure cooker and the hot oil ( Thermal Fluid) is not.  That is  why I am trying to convert this steam kettle to a modified and hopefully simple, hot oil kettle. I will heat the oil in a remote reservoir using a propane gas burner and pump it inside the steam kettle jacket. I want to circulate my hot oil inside the steam jacket where the steam is circulated.   I will adjust my heat to what ever temperature is needed to slowly raise my syrup temperature to the  desired temp.of 226-F to 230-F. I am considering using an oil pump from an Automobile engine or large Diesel engine, new or cleaned very well.  That is my plan but I am not sure if the hot oil and the steam circulate inthe same way. My hope is to find someone with some knowledge on this subject so I am not faced with extensive testing. Thanks for your response.

Have you though about runing hot water. You can find hot water pumps easly, they use them to move hot water in heat sustems. What temp are you going to run?

Recently I purchased a 150 gallon Pfaudler, open top, Steam Kettle. It looks like my cast iron syrup kettle except it is stainless steel and is jacketed.I want to try and use a remote, propane heated, thermal fluid heater.  My plan is tocirculate the hot oil instead of circulating steam.  All components except a hotoil circulating pump will be home made. Has anyone done anything like this?Any information about how to do this modification will be appreciated. The kettlewill be used to make sorghum syrup using the batch method.
