How can i make dry milk at home

Place a fruit roll inserted in the dehydrator tray and pour one cup of milk into each tray. Set the dehydrator at 130°F – 135° and dehydrate. It will take roughly 12 hours for the milk to dry. After the milk is completely dry and flaky, crumble it into pieces and blend in a mixer until it forms a powder.

To turn into milk:

Slowly combine about 1/3 cup of milk powder with 1 cup of cold water. It’s best to add just a tiny bit of water, stir the water and powder together into a paste, and then add the rest of the water, stirring continuously.
