Best practices for cleaning a Harvest Right freeze dryer?

April 5, 2026

Quick Answer

To clean a Harvest Right freeze dryer, mix 1 tablespoon of baking soda with 1 gallon of warm water to create a gentle cleaning solution, then gently scrub and rinse the interior with a non-abrasive brush and clean water. This process should be repeated every 1-2 months for optimal performance and hygiene.

Pre-Cleaning Preparation

Before cleaning the freeze dryer, ensure the unit is powered off and unplugged from the electrical outlet. Remove any food debris or residue from the shelves and baskets, and discard any expired or spoiled food products.

Cleaning the Interior

Mix 1 tablespoon of baking soda with 1 gallon of warm water to create a gentle cleaning solution. Dip a non-abrasive brush into the solution and gently scrub the interior surfaces, paying particular attention to areas around the condenser coils, fan, and any areas with visible buildup. Rinse the interior with clean water to remove any remaining residue, and repeat the process if necessary.

Sanitizing and Drying

To sanitize the freeze dryer, mix 1 tablespoon of unscented chlorine bleach with 1 gallon of warm water. Dip a clean cloth into the solution and wipe down all interior surfaces, paying particular attention to areas around the condenser coils and fan. Allow the freeze dryer to air dry for at least 30 minutes before returning it to service. It’s also recommended to run a dry run cycle (without food) after cleaning and sanitizing to ensure the unit is functioning properly.
