Blanket Warmer Build

post #1 of 17
Thread Starter 

This smoker started out life as a hospital blanket warmer. I figured it was a good candidate for a smoker since it was all stainless construction and was well insulated with dense fiber glass panels.


The original analog controls and heat elements were undersized for a smoker, so I replaced them with a 2400 watt, 240 Volt oven element, PID controller w/ thermocouple, and an SSR.


The Taylor digital thermometer is for monitoring the meat temperature.


The box on the lower right side contains a pellet hopper, gear motor, timer module, and feed auger. When the smoke generator is switched on, it feeds pellets inside to a combustion tube that contains a separate 100 watt heater element to ignite the pellets and keep them smoldering. The timer module cycles on and off that is adjusted for optimum pellet feed rate. Ashes collect in another metal box underneath.


I added an air inlet and outlet with manual damper controls, since it came without vents. Originally it had a separate upper and lower compartments. The partition was removed to make one large compartment.


I installed it in the basement of my house. As it turns out, the doors seal tightly and there is very little smoke leakage. Just enough aroma to let you know something good is cooking inside.


So far, I have smoked deer sticks, summer sausage fatties, and an easter beef brisket with very good results.

How are you venting the smoke from the top of the smoker.  It looks like you are using the flue of your furnace.

Cool idea!  Looks like it's big enough to smoke for a heck of a crowd!  PDT_Armataz_01_40.gif

Very nice! I'm curious about the venting, too. I thought about making mine a permanant fixture in the garage, but I didn't want to have to punch a vent hole in the siding or roof.

This smoker is vented out the top, and yes, it is connected to my furnace flue stack. Just using flexible 4" dryer vent for the connection. I think the good draw on the stack helps manage any excess smoke issues inside the house.  I had some reservations about creosote build-up but so far it has not been an issue. I continue to monitor it. Your milage may vary.


I would be happy to share information on any aspects of this build.

PH, morning and thanks from a lot of folks who will appreciate the parts list and drawing....   77.gif....  There are many of us that can build things with a little direction and a tutorial that you have provided...  and we can be totally helpless without it...   Dave

Added a couple drawings to one of my replies. One is a mechical drawing of the chip feeder/smoke generator. Also a cleaned up wiring diagram.

Now That Is an Awesome Idea!! How cool is that to have a smoker in the basement?? I wonder if I could wheel out the blanket warmer next time I am at the hospital without them noticing......icon_mrgreen.gif

A friend of mine discovered a surplus blanket warmer years ago. I told him if he didn't buy it I would. He bought it (for $100) and was good enough to let me help with the conversion. It has since spent most of it's time outside and I am not too sure if it even works anymore. I have left the area and tried a freezer conversion (that I am not too happy with). I have always kept my eyes open for another blanket warmer but haven't had any luck.

Where did you find this unit? and may I ask how much you paid?
