I'm new to all this and just got my MES 40 BT and A-Maze-N tray today. The MES is seasoning right now.
Can't you just put the tray in the bottom of the MES workout doing the whole mailbox deal? I don't think it would produce much heat.
Hi there and welcome!
A number of guys do just that to smoke meat. They pull the chip loader out at various degrees (like half way out) to make sure there is plenty of airflow for the pellets to burn.
As for heat I have read mixed reports. If you are trying to do a cold smoke keeping temp under 65F then I think the AMNPS inside the MES may produce too much heat unless you take measures like loading frozen water jug gallons to keep temp down. As for 100F or so "cold" smokes (more like warm smokes) I think it may not be such an issue.
When doing Salmon Lox it is my understanding that you don't want to exceed 65-70F.
Also a good tip for you. Microwave your pellets for like a minute and 10-15 seconds and it will zap the unseen humidity that the pellets are holding onto and they should burn better in the AMNPS. I actually to two microwave rounds 2 minutes apart just to be sure :)
I hope this info helps.
