I am trying to conceptualize a way to build a rocket stove that will accomplish at least two things:

1) Sterilizing grains or liquid for LC in jars at around 250 degrees F

2)Use the same stove to heat water (NOT under pressure) to pasteurizing temperatures (140-170 degrees F) for substrates for mushrooms

I just started thinking about this idea today, but I would like to be able to do about 55 gallons of substrate at a time and around 20-40 one-quart jars of grain/LC (or 5-10 one-gallon jars?) at a time, if possible. Ideally, I will build upon the design over time and stack more functions into the rocket stove, but I am in South Texas and do not need the thermal mass as much as individuals in northern climates! So possibly a cook stove addition in the future would be nice, but my main focus is to be able to work with mushroom growing medias with low input in an area where I do not have access to electricity.

Anyone have any design ideas?? I will keep updates if/when I come up with and start designing a system!!

Here is a very rough sketch of what I was thinking. It is not to scale and is obviously a simple picture, but I wanted to get a visual and general description up , so that I may be able to get feedback.



So this is an aerial view of what I conjured up in my head so far. I was thinking a simple pour-able core similar to the ones that the gents used for the cook stoves on the better wood heat DVDs. Come off the manifold with a "T" piece and go to two different barrels with baffles...to be able to control the amount of heat to each one. Both barrels would be pretty much like vertical barrel stoves (barrel in barrel with insulation in between). One would probably be similar to a dry oven for the grain jars (need to research to make sure that this will actually work for effective complete sterilization) and the other would either be filled with water that heats from radiant heat through the barrel, or maybe just some water in the bottom of the barrel somehow to create non-pressurized steam inside the barrel to reach pasteurization temperatures.

Will this potentially work? Do I need to scratch this design and dream up something different? Any ideas or suggestions are welcome!!
