How to Freeze Dry Coffee

Here is the step-by-step guide to freeze-dry coffee.

Step 01. Brew the Coffee

Start brewing a large quantity of coffee by using high-quality beans to ensure the best flavor. The coffee is usually brewed stronger than usual since it will be concentrated during the freeze-drying process.

Step 02. Concentrate the Coffee

The brewed coffee is often concentrated by evaporating some of the water. This helps to intensify the flavor before freeze-drying.

Step 03. Freeze the Coffee

The coffee concentrate is then rapidly frozen to around -40°C (-40°F). This creates small ice crystals throughout the coffee mixture. The freezing process needs to be quick to make sure that the coffee’s flavor compounds are well-preserved.

Step 04. Vacuum Drying

The frozen coffee is placed in a vacuum chamber and under the vacuum, the temperature is gradually increased which causes the ice crystals to sublimate directly from solid ice to vapor without passing through a liquid phase (a process called sublimation). This process removes the water content while leaving behind the dry coffee solids.

Step 05. Granulation

The dried coffee is then broken down into granules or powder, it depends on the desired final product, but sometimes the coffee is combined into larger granules to make it more soluble in water.

Step 06. Packaging

The freeze-dried coffee is packaged in airtight containers to prevent moisture from entering and degrading the coffee. The packaging often includes oxygen absorbers or nitrogen flushing to extend shelf life and preserve freshness.
