Do not assume a fixed gap; use product instructions, container model, packaging and measured load trials.
There is no universal plate-to-product gap. Check product freeze sensitivity, packaging and container plate-slot design; verify from instructions whether direct contact is allowed. In a trial, place sensors at product-risk positions and log a representative load. Review results against product criteria and document the suitable separator arrangement.
Separation from a plate must be validated for the product, container and plate model. One fixed gap does not assure every load.
Review product specification and packaging alongside plate slot, separator and airflow instructions. Make any contact restriction visible in the loading instruction.
Place sensors at the most sensitive positions for a representative load trial. If product results fail criteria, change placement or separator and revalidate; record the layout in a diagram.
