Wow....I've never seen anything like that. Keep in mind that there is two distinctively different kinds of smokers:. Cold smoke and Hot smoke. Don't quote me here, as I am still in my rookie training with about 40-50 smokes under my belt....but I think that might be a cold smoker. Think Alaska smoked salmon from the store. It's fully cooked, but looks almost raw, and looks nothing like traditional smoked meats that are hot smoked like RyBZ and Pulled/Chopped Pork and Briskets. I believe the target temps for cold smoke are in the 175° area...I've seen commercial could let smokers that look almost like a commercial pizza proofer box. A stainless box the size of a fridge with an electric heating element....the way they make that smoked salmon u see in the store. I smoked some fresh caught by us great lakes salmon and rainbow trout with Hickory at 225° or so and it looked and tasted nothing like cold smoked salmon. It was more like super tender salmon jerky with tons of flavor. Quite good indeed. Just by looking at the setup in the pic (which is gorgeous by the way) I don't think it is meant to get over 180°. I bet that pic is from Alaska where everyone cold smokes salmon over green Alder wood....to survive the winter. Those guys live on Pacific Salmon. Just a little heads up before u go out and start buying stuff to whip it up, lol. I have seen a bunch of homemade 35 and 55 gal drum smokers in backyards, especially in the ghetto, while we are doing tree work. You see all kinds of stuff up there wandering around back lot lines. The PBC (Pit Barrel Cooker[emoji769]) is made from a brand new drum....but is run vertical, and uses hooks to hang RyBZ vertically. Solid 5 star reviews and it's only about 2 bills. Check it out for a killer affordable hot smoker that's made in the states by metal workers.
