Electric Smoker OR Landfill: What say you?

Surg We’ve actually looked at smaller dry curing chambers more aimed at home processors BUT there are so many moving parts to those things and so many that can go wrong that we are hesitant to go forward with it. Trying to balance affordability with reliability.

Or maybe a kit of items people can use to convert a home fridge?

Today I stripped the cooling coil/shelves out of the main cabinet and removed the plastic door shelf assembly and gasket from the door.
On this freezer, the cooling coils are used as shelving units and are interconnected by steel refrigerant lines. My goal is to remove the excess refrigeration lines but retain the shelves because I think after they have been cleaned up, they will work pretty good for things like jerky or fish. I also would like the option to be able to remove them so I can hang product on sticks. It’s good to have options
Since my freezer had developed a leak, all the refrigerant was gone and I could cut the lines without worrying about pressurized refrigerant hazards or releases. Be aware if you are converting a freezer/refrigerator that still has a charge. you should properly evacuate the refrigerant, before cutting into the system. Use PSE and be aware or the hazards before working on a charged system.
I also plan to remove the compressor to lighten up the cabinet.
Note that the plastic shelving unit on the door is attached by screws under the gasket. To remove the shelf, you just take out the screws. With the shelf removed, I can replace it with a sheet metal panel and reassemble using the old screws and door gasket. The plastic parts would eventually melt and could off-gas fumes that don’t belong around food.
processhead thanks for doing this. It gives me a little confidence in trying it myself.

Here is the 1500 watt hotplate I ended up buying for the smoker heat source. I downsized the overall wattage so it would stay under the maximum amperage of a 15 amp 120 volt household circuit. It should still be adequate to heat the freezer cabinet I am using.
I got it from Amazon for about $28.
Since I am going to use an external controller, I wanted to remove the internal thermostat.
Opening up the case of the hot plate you can see the bimetal thermostat with the two red wires connected to the left side and the knob on the outside.I still want some overtemperature connection so I added a klixon type self-resetting 300 degree overtemperature switch where the adjustable t-stat was connected. That way, if there is a malfunction that were to keep the hotplate turned on all the time, the overtemperature switch would offer a measure of safety.
With this change, the hot plate will come on as soon as power is connected to the plug. Later we will talk about how the external temperature controls will switch the power on and off to the plug to regulate the smoker temperature.
EDIT: During testing, I found that the internal temperature of the burner exceeded the rating of the over-temperature switch. The hot plate would come on, and then shut down before the cabinet heated up.
I removed the overtemperature switch from the hot plate and directly wired the power cord to the heating element. This corrected the problem.When using an over temperature switch, install it in the main cabinet away from the heating element.

processhead I’m beginning to think I may not be smart enough to do this. Lol. But I’m not giving up yet.

Some guys will just use the hot plate control inside the smoker, but you won’t have the ability to control the temperature as accurately if you do.
Also, you would have to open the door every time you made an adjustment, letting out heat in the process.
Using external controls with the hot plate enables more precise control and is much more convenient.

Every smoker needs some means of controlling air flow through the chamber. Physics dictates that warm air rises so on a vertical smoker you normally see an air inlet in the bottom which draws ambient air and a discharge opening in the top where warm air and smoke exits. These opening will often has some sort of damper to control the rate of flow.
I will be installing a 4 inch round duct thimble into the top of the smoker which will require cutting a 4 inch diameter hole through an inner and outer layer of sheet metal and about 1 1/2 inch layer of expanding foam that forms the insulating jacket of the old freezer.
Many refrigerators and freezers will have condensing coils installed in the space between the inner and outer layer of the top and sides of the cabinet. This freezer did too and after cutting through the top, I was able to push the lines out of the way to continue all the way through.
I used a 4 inch hole saw to cut the first hole in the top. The hole saw was difficult to control so I used a saber saw with a metal blade to cut the second hole through the inner layer of sheet metal.
I flipped the cabinet over onto it’s top to make the second cut through the inner layer of sheet metal, which is why one of the photos looks upside down.
After I cut the opening, I positioned the thimble in place and sealed it in with expanding foam. My experience with expanding foam is that once it has cured, it forms a very good seal and is mechanically very strong.
The weather cap goes on top and it has a rotating damper plate. The damper plate will regulate the smoke and hot air exiting the top of the smoker.

processhead Nice Job. There are going to be a lot of people looking at this project.

processhead Have you worked with or researched any combination temperature and humidity controllers that you recommend? So many out there and quite a price range.

I have not done much research, but am generally aware that the controls are out there and getting more affordable.
What I have not seen are good plug and play humidity sources that are affordable and have good control capability for our processing applications.

Chef Done the build on the “Sausage Maker” combination temperature and humidity controller setup before. Getting hard to find metal lined refers to convert these days. Sausage Maker, Pricey but reliable. I will be in their Buffalo NY store in a few days. Will send pics and specs if you want. They do sell all the parts for the build as needed. Cheers

JoeB Yes, please send pictures. I’ll be lining with sheet aluminum whatever unit I use.
Thanks

I would be interested in seeing what they offer too. Thanks for offering pics and specs.

Chef Please to share your proposed method to line a refer with aluminum. What are you using to seal the vertical and horizonal meeting Planes?

Just a short progress report. The original plastic shelves on the door are gone and replaced with sheet metal. I used aluminum trim coil that I cut and fit to the same dimensions as the plastic shelf. The trim coil was not wide enough to do with a single piece of material so I cut two pieces that overlap and used contact cement to attach them together. You have to look hard to see the joint.
I hung the door back on the cabinet to convince myself I am making progress. lol
