Video Overview: Getting Started with Your Freeze Dryer
This video tutorial provides a quick overview of how to operate your freeze dryer, guiding you through the three crucial processes – freezing, drying, and final drying. It also covers essential preparation steps to ensure a successful freeze-drying cycle and packaging tips to store your freeze-dried goods effectively.
Processes:
Step 1: Freezing – Speed up the freezing process by pre-freezing your food before placing it in the freeze dryer.
Step 2: Drying – Once frozen, the unit enters the drying mode. It transitions to the final drying stage when most of the water is believed to be removed.
Step 3: Final Drying – After the final drying, remove your food for packaging.
Getting Started:
Step 1: Pre-cool the Freeze Dryer – Turn on the freeze dryer 30 minutes before loading to ensure it's cool.
Step 2: Prepare the Food – Cut your food into medium slices or pieces, and place them on the trays without stacking, except for small items like peas, corn, or herbs.
Step 3: Load the Trays – Slide the trays into the unit. For runny liquids, pour them into the trays after partially sliding them into the freeze dryer.
Step 4: Start the Freeze Dryer – Ensure the drain valve is closed, then let the freeze dryer run. The process is automatic, typically taking 24 to 50 hours, depending on various factors.
Checking for Dryness:
Step 1: Release Vacuum Pressure – Open the drain valve and door to check the dryness of the thickest food piece.
Step 2: Assess Dryness – Break the food in half to check for water, or place it on your tongue to detect ice. If not dry, add more time.
Packaging:
Step 1: Remove Food – Once dry, remove your food from the freeze dryer.
Step 2: Package Your Food – Use mylar bags or canning jars for packaging. Include an oxygen absorber in the container and seal it properly.
Step 3: Store Leftover Oxygen Absorbers – Reseal leftover oxygen absorbers immediately to prevent them from going bad.
Step 4: Prepare for the Next Batch – Change the oil before starting a new batch, ensuring no water gets into the pump.
