How Freeze Drying Works (Video)
Steps to Freeze Dry Food
- Fresh or cooked foods are placed in the dryer where they are frozen to -40° F or colder.
- Once the food is frozen, the dryer creates a powerful vacuum around the food. Then, as the food is slightly warmed, the ice transitions into vapor and is drawn out of the food.
- The freeze-dried food is then sealed in moisture and oxygen proof packaging, (e.g. easy close bags) to ensure freshness until opened.
- When water is added to the food it regains its original fresh flavor, aroma, texture, and appearance!

In-Home Freeze Dryer
Technical Stuff About Freeze Drying at Home
Our in-home freeze dryer is an amazing appliance. It uses a condenser that brings food to -40 degrees Fahrenheit — and in combination with a vacuum pump that creates a vacuum inside the drying chamber — it makes freeze drying at home possible for everyone.
In a vacuum, water can only exist as a gas or a solid. While in the vacuum environment inside the freeze dryer, the dryer gently warms the food before freezing it, causing the water inside the food to sublimate off as a gas.
The gas then sticks to the inner walls of the freeze drying chamber to keep it away from the food as the rest of the freeze drying process completes.
After the machine finishes its 24 hour cycle, it then self-cleans all on its own. Thanks to the smart technology that we build into each dryer, the entire process is completely automated with the push of just one button!
Home Freeze Drying Before Harvest Right
The kind of user-friendly home freeze drying that we’ve explained here was not possible for the average family before we developed our home freeze drying machine.
In addition to being far too expensive for the average family, older freeze dryer designs required the user to understand complicated machine settings and to monitor and adjust those settings while the freeze drying machine was in operation.
For most families, both the cost and work involved in freeze drying at home just wasn’t feasible. Often, the only option left to families who wanted to create their own freeze dried food storage was to spend thousands of dollars on already-dried food.
All that has changed for the better now! Not only does the Harvest Right machine do all the work for you, but it can save your family money in several ways.
3 Ways Freeze Drying at Home Saves Money
Freeze drying food at home saves families money in many ways. Here are just three to consider:
1. Food Waste Management
The average American family wastes thousands of dollars of food each and every year.
By freeze drying your leftovers and surplus food, you will turn food waste into an investment — either by making a on-the-go snacks for your family to enjoy later or by boosting your food storage.
2. Low Power Usage
We designed our freeze dryer to be easy on your power bill. There’s no sense in trying to help families save money in one area just to cost them in another.
The dryer plugs into a standard 110v power outlet and draws an average of 9 amps of power per hour (about 1,000 watts).
3. It Pays for Itself
When used to dry food daily, your machine will pay for itself much sooner than you might think.
Considering the low cost of the machine, most families will be able to dry enough food to fully return on the investment in just over a year. We designed our food dryer to stand the test of time, even when used continually, and the food you freeze dry with it can last up to 25 years.
We’re proud to offer one of the first home appliances of its kind that gives lasting value back to its owners.
