Build two removable shallow plates 1/2" - 1" high or so, to fit the RF plate but have wiggle room to remove, put handles on the plates for easy removal.
During cooks one plate can be removed set aside to cool as the other one is placed inside . No loss of production time as this can be done on the fly.
If you scrape each time that cuts into your production time. The removed plate once cooled enough to handle then can be cleaned and set aside till its time to change it out again.
add ¼" raised feet to the pans for air circulation underneath the pan, this will alleviate the charringIf i raise them up off of the plate, hopefully it wont turn into the chared sruff im getting now
