Recommendation: Maximize Airflow
The horizontial airflow within the chamber moves from the small duct holes on the right hand side of the chamber across the shelf space to the large duct holes on the left side of the oven internal wall. Place the shelves as to not block the holes. This maximizes airflow. Space the shelves evenly to insure the best temperature uniformity and air circulation.
Ground-Up, Light Weight Material? Less Mess With Temp Rated Mesh Bags
Cascade also makes temp rated mesh bags designed to fit on the CDO-28 Shelves. If your product is subject to turbulence during a forced air drying or decarboxylation process, the mesh bags allow for airflow and keep product turbulence down.
