Answers to your Home Freeze Dryer questions...

Here are our most common Home Freeze Dryer questions and their answers. If you still have questions, please contact us.

How does the freeze-dryer work?

The entire process is automatic.

  1. Raw or cooked foods are placed in the freeze dryer where they are frozen to between -30 degrees and -50 degrees Fahrenheit.
  2. Once frozen, the freeze dryer creates a vacuum in the food chamber.
  3. As the food is gradually warmed, the water turns to vapor and evaporates out of the food (sublimation).
  4. When dry, the freeze dryer notifies the user that the process is complete by sounding an audible beep.
  5. You can then remove the freeze dried food from the dryer and place it in vacuum-sealed containers that are moisture and oxygen proof (preferably a mylar pouch or a can) to ensure freshness until opened.
  6. When water is added to the food, it regains its original fresh flavor, aroma, texture, and appearance!
What size are the freeze dryers and how much do they weigh? The freeze dryer is smaller than a dishwasher and larger than a microwave. The sleek design makes it the perfect size to reside on a countertop, cart, or table. The exact dimensions are listed on the respective product pages.
What types of food can be freeze-dried?

You truly can freeze-dry almost anything. All kinds of fruits, vegetables and meats taste wonderful when freeze dried. That includes things like tomatoes, apples, bananas, strawberries, peaches, green beans, peppers, onions, potatoes, spinach, shrimp, pork, beef, turkey and even ice cream.

Your favorite meals that include meat may be easily freeze dried. Foods like lasagna, rice dishes, cheese macaroni, chili, beef stew, chicken a la king, casseroles, shrimp, lobster, pulled pork, pasta sauces or scrambled eggs are perfect for this process.

You will find that it is a delight to experiment with different foods and meals in your freeze dryer. A great way to start is by picking meals that are already favorites in your home.

How long does it take to freeze-dry a batch?

It typically takes between 20 to 40 hours to complete the process. Food type and quantity will affect the freeze-dry cycle. Things like meat, peas and corn dry quickly, while squash and watermelon can take longer. The thickness of the food slices will affect the cycle time too.

Most importantly, your machine senses when the food is ready (alerting you with a beep) so you don’t have to guess when to stop the freeze-dry cycle.

Can I freeze food prior to placing them in the freeze-dryer? Yes! It is a great to put frozen products into your Freeze Dryer. Your machine will accept pre-frozen foods and cool them even further, to around -40 degrees F.
What maintenance is required?

Every Harvest Right freeze dryer comes with a high quality vacuum pump. Each vacuum pump comes with an initial supply of oil. There are 3 cups of oil in a vacuum pump that need to be changed regularly to keep a freeze dryer running efficiently.

Some customers choose to drain out a tablespoon of oil and add a tablespoon of oil after each batch and and then periodically perform a flush of their vacuum pump to maintain the high quality performance of their vacuum pump. Other customers choose to simply drain their oil after every batch and start with a fresh batch of oil. Many customers also choose to filter their oil in a variety of ways and re-use their filtered oil to save money. Additional vacuum pump oil can be purchased online from sites like Amazon.com or from a variety of retail locations (like an auto parts store or a refrigeration supplier).

What power outlet is required?

Harvest Right has taken every precaution to make this appliance run as efficiently as possible.

Small and Standard

Our small and standard freeze dryers use a standard 110 volt outlet.

At peak, the freeze dryer draws about 16 amps, but on the average about 9 to 11 amps (990-1210 watts) of power per hour. A dedicated 20 amp circuit is recommended.


Our large freeze dryer requires a 220 volt (NEMA 6-15) outlet.

At peak, the large freeze dryer draws about 16 amps, but on the average about 9 to 11 amps (990-1210 watts) of power per hour. A dedicated 20 amp circuit is recommended.

Where does the removed water go? During the freeze dry process, the water sublimates (evaporates) out of the food and then freezes to the walls of the chamber of the freeze dryer. Once the freeze dry process is complete, the unit has a defrost cycle that quickly melts the ice to get it ready for the next batch.
What type of warranty and tech support is offered? Simply call the Harvest Right tech support line when there is a problem. If the problem is something that cannot be handled by the Customer Support team, a local technician can be hired to come to your location. A full one-year manufacturer warranty is included with each state-of-the-art freeze dryer.
