Dry kiln for jarred tobacco.

[ShiniKoroshi]

The metal canister in the center is to house the fan and heat source. Here is where we need to do a little shopping for easy to assemble components. There are many combinations of product available.

For example....
A 4 inch (102mm) duct fan available on Amazon for $11 to $20


The fan would be connected to a flange duct connector ($8) that would be fastened to our raised floor.

The combined height of these two components will be about 9 inches (228mm). The heat source can be mounted in either the flange or the downstream side of the fan.

The heat source is a small *100w halogen lamp. Actual size .6inch x 2.25inch (15mm x 57mm) $3-$6
*100W may be too hot. I do know 50w and 75w are available.


There are many socket options for the E11 mini-candelabra bulbs. $3-$6


Don't forget that you will need a 140°F (60°C) thermal fuse. $2-$5


This is only one (on the fly) example of how you can get this together. Different fan may require a different coupling and mounting, etc. There are NO WRONG ideas and solutions. The point is maximizing the economy of either expense, effort and/or complication.

The raised floor is simply a sheet of expanded or perforated aluminum. $12
You may have to trim the corners or bend them down. Cutting the center is optional.


You can make a fancy mounting or glue a few 1 inch (25mm) sections of 1 inch (25mm) dowel to the bottom of the cooler, enough to support the glass jars but not too many to obstruct airflow.

Add the controller of your choice, some wire, connectors, tape and you're pretty much set to build a kiln.

If I should be so blessed with a tobacco harvest this(my first time growing)year, your ideas and instructions will be a blessing- thanks

Good luck with your grow and Im looking forward to seeing your kiln build.

New ideas will be posted randomly. Later Ill string it all together and maybe make CAD drawings. Anyhow....

Adding a thin sheet of aluminum to the bottom, under the false floor, will prevent the area under the heater from becoming excessively hot by dissipating the heat outward from the center. The perforated sheet (false floor) is doing the same (especially if the center was not cut out) and that heat is then radiated upward into and around the bottom of the jars.

The fan has the power cord and this is where you would splice in the thermal fuse and a line to send power back to the controller. A pair of wires would then return to the heater to power the bulb. We can tap the ground on the fan to ground the rest of the assembled unit of floor-fan-heater.
