Freeze drying without a machine is possible using a conventional freezer. Slice foods into thin pieces and place them in a single layer on a tray. Put the tray in the freezer and leave it for a week or two. Check for crispness, as residual moisture means it needs more time. Store the fully freeze-dried food in airtight containers to maintain its shelf life. This method is more time-consuming than using a machine but can effectively preserve foods at home.**
