Well if anyone is interested. Reveo got back with me, finaly, and said that a brine works great in the tumbler. The Vaccum replaces the temprature thing as a vehical to get the flavorings into the cells. They suggested that I put the product,(salmon in this case)in the tub and cover with brine, pull vaccum and tumble for 10 min, then let sit in the brine under the vaccum for an additional 10 min. I cut 2 salmon into 5 serving pcs each and tried it, worked great. The taste was perfet for me, not over powering with salt but the flavors came through. I did one with and a addition of some lime pepper which really gave it a great kick in the pants, I loved it. So I give the Reveo an A+ for functionality. It cut my total time down by 1hr. I did shave off 1/2 hr by drying it in my dehydrator in stead of just sitting at room temp under a fan. Then cooked for 45min in my 106 @ 170 deg with alder wood chips. Its perfect for me.
