How to Freeze Dry Milk

Welcome to Prepper Website!

Are you ready to learn how to freeze dry milk? Freeze drying is a fantastic way to preserve food for long-term storage. It removes moisture from the food, keeping it fresh and tasty for years to come. In this article, we will dive deep into the process of freeze drying milk and provide you with all the necessary steps to successfully freeze dry your own milk at home.

Before we begin, it’s important to note that freeze drying milk requires some specialized equipment. However, if you are a dedicated prepper or someone who enjoys the art of food preservation, investing in a home freeze dryer might be worth it.

Now, let’s get started!

Step 1: Gather the Necessary Equipment

To freeze dry milk, you will need the following equipment:

– A home freeze dryer
– Vacuum-sealed bags or containers
– Airtight storage containers

Step 2: Prepare the Milk

Before freeze drying your milk, it’s essential to ensure that it is free of impurities or foreign substances. Follow these steps to prepare your milk:

1. Start with fresh, high-quality milk.
2. Pour the milk into a clean and sterilized container.
3. Skim off any cream that has risen to the top (optional).

Step 3: Freeze Drying Process

Now that you have all your equipment ready and the milk prepared, it’s time to start the freeze drying process. Follow these steps:

1. Pour the milk into vacuum-sealed bags or containers. Ensure they are not overfilled to allow room for expansion during the freeze drying process.
2. Place the bags or containers in the freeze dryer. Follow the manufacturer’s instructions for your specific freeze dryer model.
3. Start the freeze drying process. This typically involves lowering the temperature to freeze the milk and then gradually reducing the pressure to allow the frozen water to sublimate.


– If you don’t have a freeze dryer, you can try using dry ice to freeze dry smaller quantities of milk. However, keep in mind that this method may not yield the same results as a dedicated freeze dryer.

Step 4: Packaging and Storage

Once the freeze drying process is complete, it’s time to package and store your freeze-dried milk. Follow these steps:

1. Remove the freeze-dried milk from the freeze dryer and transfer it into airtight storage containers.
2. Ensure the containers are completely airtight to prevent any moisture from entering.
3. Label the containers with the date of freeze drying for easy reference.
4. Store the containers in a cool, dry place away from direct sunlight. A pantry or basement is an ideal location for long-term storage.


– To maximize the shelf life of your freeze-dried milk, consider using moisture absorbers or oxygen absorbers in the storage containers. These can help extend the freshness of the milk by eliminating any residual moisture or oxygen.

Step 5: Rehydrating Freeze-Dried Milk

When you’re ready to use your freeze-dried milk, rehydrating it is a simple process. Follow these steps:

1. Measure out the desired amount of freeze-dried milk.
2. Add an equal amount of warm water to the milk powder. For example, if you’re rehydrating 1 cup of milk powder, add 1 cup of warm water.
3. Stir the milk powder and water mixture until fully dissolved.
4. Allow the mixture to sit for a few minutes to ensure complete rehydration.
5. Your freeze-dried milk is now ready to use in recipes, cereals, or beverages.


– For a creamier consistency, you can use slightly less water when rehydrating the milk powder. Adjust the water amounts to your preference.

My 2 Cents

Freeze drying milk can be a beneficial skill for preppers and anyone interested in long-term food storage. By freeze drying your milk, you can extend its shelf life for several years without compromising its quality.

Investing in a home freeze dryer may require some upfront costs, but it can be an excellent long-term investment for your food preservation needs. Freeze-dried milk is not only convenient but also nutritious, making it a versatile addition to your emergency food supply.
