Is it possible to can food on a biomass stove? Cooking for a lot of people and want to use a biomass stove? Check out this latest SilverFire biomass stove – it can answer both these questions.

“What about canning on a biomass stove? Can the heat be regulated well enough to use a pressure canner?”
This question has come up frequently. I used to say “no” because regulating the heat on a biomass stove was an iffy proposition. And with standard biomass stoves, the constant fuel feeding would be a really tedious chore.
But this latest innovation from SilverFire will change all that.
Biomass stoves are the wave of the future, IMHO. They are fueled with biomass materials, and produce intense cooking heat. The advantage over other types of stoves is that they operate on twigs, wood chips, small sticks and virtually any form of organic material. The downside is that many biomass stoves require almost constant fuel feeding, and the cooking temperature varies quickly with the fuel intake.
I stopped by the SilverFire booth at the June Mother Earth News Preparedness Expo in Albany, Oregon in June. I found the company had addressed the canning issue with their newest stove, the SilverFire®Super Dragon with Pulse Width Modulater Fan Speed Control.
Several stoves were set up and working. I am familiar with the whole product line, and use them regularly. The SilverFire Scout® is my stove/cooking setup for backpacking – provided there are no fire closures in the area. My Survivor® is another winner.
But the Super Dragon may top all these. It kicks out heat like a blow torch, and the output can be regulated with the twist of a dial from simmer to too damned hot.
Here’s some of the nuts and bolts about the Super Dragon:
The Super Dragon is a top lit updraft gasifier. It is simple to operate. Insert vertical positioned fuel into the combustion chamber; next place a little tinder on top and light. To fine tune the flame adjust the primary and secondary air control knob on the stove. These regulate air flow through mechanical orifices, designed in the fan housing.
This system works really well in all the SilverFire toploaders.
There are no electronic parts to fail, except possibly the commonly-available and durable 12V (0.48A) blower fan. Super Dragon’s operate somewhat like a LPG gas stoves.
An off grid product should work without electricity, IMHO. The more gadgets and doodads added, the more complicated the item becomes, and more prone to failure. So I was curious to see how this forced air fan could be powered.
Todd Albi, owner and designer of the SilverFire line of biomass stoves, said the Super Dragon came about because people wanted more control over the heat output, and needed a way to regulate temperatures. They also needed high, sustained heat. This heat had to be accurate enough to work with a pressure canner.
This issue was solved with a fan powered with 110-volt AC adaptor that comes with every stove, a concentrator ring, and a cast iron trivet with pot supports. This stove is designed for large volume pots, not a small pot.
The Speed Pulse Width Modulater (fan) is included with the Super Dragon stove for accurate heat control for canning, and low power cooking for delicate cooking (pancakes, crepes, eggs, etc…). Just plug in the PWM into the Super Dragon fan housing, add power cord and the dial control will allow you to set the fan speed at what ever setting you need.
In addition to the AV/DC option, the small fan easily runs off any 12 volt DC battery pack or small portable solar panel.
Albi was running the stove with the fan powered by a solar panel from Harbor Freight. The fan has a 12 volt input, meaning, it could be run off virtually any motorcycle, truck, forklift etc. battery. And Albi claims that means the stove fan could run almost indefinitely.
“The fan only draws three watts. The dome light on a truck pulls 12 watts,” Albi said. “You could get years of use off one forklift battery.”
The Super Dragon is easy to light, easily adjusted, lightweight, and cooks very rapidly. Thin tight packed fuel produces a very rapid boil. If you want to slow the cooking process down (e.g. slow cooking with cast iron) add thicker, dense fuel into the combustion chamber.
Dense material takes longer to burn, and is ideal for slow cooking on the charcoal ember selection setting. Combustion in the Super Dragon produces minimal emissions, if using dry fuel. The only residue left is minute fine ash, due to the efficient combustion.
I like the SilverFire line of products, and have recommended them for a variety of uses. For the prepper or preparedness types, who want the ability to can food when the power goes off, this is a really good investment.
Also, IMO, a good biomass-powered stove should be in every preparedness kit. The SilverFire Super Dragon is a good choice.
