A horizontal stack exposes outer plates to cold air while covering the broad surfaces of those in the middle. GEBHARDT calls for an air gap between plates.
Do not stack plates on top of each other: the outer ones may freeze while the middle ones do not freeze enough. GEBHARDT requires an air gap between plates at all times, a freezing temperature at least 5 °C below the melting point and a fully frozen fill. If the arrangement changes, check one plate from the middle and one from the edge separately.
A horizontal stack exposes outer plates to cold air while covering the broad surfaces of those in the middle; a batch can look ready from outside while the inner row is not frozen. GEBHARDT calls for an air gap between the plates, a freezing temperature at least 5 °C below the melting point and a fill that is completely frozen before use.
| Melting point | Recommended freezing | Duration |
|---|---|---|
| -3 °C | -8 °C | 24 h |
| -14 °C | -19 °C | 24 h |
| -18 °C | -23 °C | 24 h |
| -21 °C | -26 °C | 24 h |
