I am sorry that I am late in seeing/responding to this one. I have some Encapsulated Citric Acid that I purchased on my last Walton's order but have not used it yet.
Did you try this? If so, how did it go?
I would think you could just go at it with your normal smoking process because as long as you are using your Jerky dryer, it should dry the casings out. If your casings really seem wet, you could run the smoker at 100 degrees or so with the fan on for an hour or so to dry the sticks out prior to going forward with your smoking cycle.
These are my thoughts anyhow. For a more expert answer, you could ask your question on the Walton's user forum and Austin or Jonathan will be able to answer your question with a lot more expertise.
I am looking forward to trying this sometime on some summer sausage, just waiting for the weather to warm up a little bit.
