Freeze-Drying Process
- Load the Freeze Dryer: Place the cooled refried beans onto the trays, ensuring they are spread evenly.
- Start the Machine: Follow the manufacturer’s instructions for your freeze dryer. For example, on Harvest Right machines, select the “Non-Liquid” option.
- Monitor the Process: Freeze-drying can take up to 33 hours, depending on the batch size. Check for dryness by feeling the beans; they should be hard and flaky.
- Store Properly: Once dried, store the beans in Mylar bags or airtight containers with oxygen absorbers to extend shelf life.
Rehydrating Freeze-Dried Refried Beans
Rehydrating freeze-dried refried beans is simple. Use a 2:1 ratio of water to beans. For example, if you have one cup of freeze-dried beans, use half a cup of water.
