Freeze-drying is a process that helps preserve food while retaining up to 97% of the nutritional value and moisture content of the food. In contrast, canning only keeps 40% of the food, and dehydrating only keeps 60%.
It’s also becoming a popular option for camping, survivalists, and people who just want to save money by buying in bulk and preserving their food instead of throwing it away.
The freeze-drying process has been used commercially since the 1950s, but many myths exist.
In this article, I’ll discuss the buying guide, which is jam-packed with advice, tips, and recommendations on the best freeze dryer and what to look for when purchasing one.

On-growing costs when you own a home freeze dryer
Vacuum pump oil
This item costs between $25 and $35, depending on where you buy it. It’s important that you get a freeze dryer with a long-lasting pump so that you don’t have to change it often
My 3 tips to save money on vacuum pump oil
- First, do not overfill your freeze dryer. If too much oil is in the tank, it will be unable to extract all of the air from the container. A good rule of thumb is to fill it up about halfway.
- Second, you should make sure that your lines are clear from ice build-up or other debris. This will help prevent any clogs that may occur during use and cause leaks or other issues with your vacuum pump oil system.
- Finally, make sure that your freeze dryer is clean by wiping off any dirt with a damp cloth before starting up again so that this doesn’t happen again!
Why should you buy a home freeze dryer?
You can stop wasting food.
We all feel bad about wasting food.
Whether we’re tossing out the last bit of produce before it goes bad or throwing away leftovers because they’re past their expiration date, wasting food is just a fact of life. But what if you could stop the waste? What if you could use your leftover produce to make something delicious?
You can with a home freeze dryer!
You can preserve your home grown produce.
You know how it’s always nice to have a nice, fresh batch of homegrown tomatoes in the fridge. But it’s hard to get them there without throwing away the seeds.
But what if I told you that you could freeze-dry those tomatoes and save them for later? What if you could also preserve your homegrown herbs? What if you could use those herbs in all kinds of delicious dishes and recipes?
This is where a freeze dryer comes in. A freeze drying machine allows you to preserve food items without wasting it. You can keep your herbs fresh and ready for use all year round. And if you have kids or family, it will save them money on food because they won’t have to buy as much!

What is a home freeze dryer?
Home freeze dryers are kitchen appliances that help you freeze-dry your food.
It uses heat and air to remove moisture from foods such as meats, vegetables, fruits, and herbs. Food drying has numerous advantages.
They can be used to freeze dry candy, fruits, vegetables, and other foods that need to be kept fresh. They come in different sizes, so you can find one that works for your space.
How does a freeze dryer work?
The drying food process consists of 3 steps:
The first step in the process is freezing. This is done by placing food on large open racks to allow air circulation.
The freeze dryer lowers the temperature inside the vacuum chamber to an incredibly low temperature (around 40 degrees F).
Once the food is completely frozen, a vacuum pump lowers the pressure inside the chamber. And then the temperature is slowly raised back to normal.
2. Lowering pressure
Lowering pressure is accomplished through sublimation, which is when solid ice changes directly into water vapor without ever becoming liquid.
The end product gives up its water content without sacrificing texture, flavor, or nutrition.
A food dryer works by sublimation, which means you’re removing moisture from the food and drying it.
3. Removing the moisture through sublimation
The most common method of removing moisture from food is through sublimation.
Sublimation is a process by which a substance turns directly from a liquid to a gas without going through the liquid phase.
When you heat something up, it expands—that’s part of what makes things like toast pop out at you when you hit them with a pan.
But some molecules in your food aren’t able to keep up with this expansion, so they get left behind as a solid form: that’s sublimation!
Drying your food using a food dryer involves heating it up until they start turning into vapor; then, it’ll be left behind as tiny particles (vapor).
You can think of them as little bubbles in your food that are invisible to the naked eye but are releasing moisture that would otherwise be in your food.

About Harvest Right
Harvest Right is a company that specializes in freeze-drying machines and helps people keep food fresh.
They have three different sizes of each product type for home use and use in a pharmacy.
They also make and sell 3 different types of pumps for your machines: the Vacuum Pump, the Premiere Vacuum Pump, and the Oil-Free Pump.
The main differences between these pumps are how often you have to change the oil (or not use oil in the case of the “Oil-Free Pump”) and if you can use it on your machine. For example, some of them may need an adapter.
Usually, when you buy a freeze dryer, the trays, some Mylar bag units for storage, oxygen absorbers, and an impulse sealer are already included (you can also buy them separately after, as well as other accessories).
The Harvest Right Freeze Dryer was found in Salt Lake City, Utah, where it was designed, engineered, and tested.
They worked hard for four years to make this product, which they then sold worldwide.
Things to consider before buying a home freeze dryer that meets your needs
If you’ve decided to purchase a freeze dryer, you must still consider these factors before making a payment.
Most freeze dryers tell you how big the vacuum chamber is and how much food you can put in it at once.
If you’re only “cooking” for yourself and your partner, you can get away with a smaller dryer.
If you need to feed many people or want to make more than one kind of food at once, you’ll probably need a bigger dryer.
If you’re considering buying a freeze dryer, you’ll need to consider how much space it will take up in your kitchen.
Most large freeze dryers are roughly the size of a dishwasher, but some smaller models can fit on a countertop.
The electricity you can provide
The electricity usage will be a huge factor in determining what kind of freeze dryer you’ll need.
If you’re planning on using this in a very small space or looking to save money, it might make sense to purchase a smaller model.
The large pump and other machinery in a freeze dryer can take some serious power. You may need a dedicated electrical circuit for the larger models.
The final factor to consider when purchasing a home freeze dryer is the amount of maintenance required.
Most of them require little maintenance, but they require cleaning and inspection of the door seals and other important parts.
In addition, most come with a vacuum pump that requires oil changes on a regular basis. Some allow for an upgrade to an oil-free pump, but it comes at a premium.
Food Freeze Dryer vs. Food Dehydrator: What is the difference?
They’re both great at removing water from foods for storage. The difference between a freeze-dryer and a dehydrator is their use of heat.
Freeze-drying is a process that uses low heat to remove about 95% of the water from foods, while dehydrators use a combination of heat and vacuum to remove about 80% of the water from foods.
Both methods are great for preserving food, but one is better for some types of food than others. For example, freeze-drying works best on fruits (ex: freeze-dried strawberries) and vegetables with high sugar content (like apples, bananas, and avocados), but it’s less effective at removing excessive amounts of fat or salt.
Dehydrators work better on meats and other foods with high protein content (like beef jerky or chicken breasts), but they can’t handle dehydrating foods with very high moisture content (like fruit leather).

Does freeze drying remove nutrients?
No! Freeze drying doesn’t remove nutrients. The process uses a vacuum to remove moisture from the food so that it’s still preserved and won’t rot when it’s frozen. The food is dehydrated but not cooked.
How long does it take a freeze dryer to freeze?
It depends on the size of your freezer and the amount of moisture in your food. If you have a large, well-insulated freezer, you’ll probably be able to freeze dry in 24 hours or less.
