What is Freeze Drying?
Freeze drying, also known as Lyophilisation or Cryodesiccation, is the process of dehydrating food through low temperatures and involves freezing the food, lowering pressure by using a vacuum pump, and then removing the ice through sublimation. Sublimation is the transition of a substance directly from a solid to a gas, without passing through the liquid state.
Freeze drying is different from conventional methods of drying such as dehydration which uses heat to evaporate water from a food item.
“Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate, unique, and interdependent processes; freezing, primary drying (sublimation) and secondary drying (desorption)”FDA, Food and Drug Administration
How Does a It Work?
Today’s home freeze dryers make freeze-drying very simple. The way that it works can be summed up in the below steps:
- Select the food items, place them on the tray/sheet, slide the trays into the freeze dryer, and press start.
- I like to freeze foods on the tray in my freezer before placing them in the freeze dryer to make the freeze-drying process more efficient, however, it is not required to do so.
- Freezing phase: the freeze dryer freezes the food to between -30 degrees and -50 degrees Fahrenheit.
- Vacuum Pump: Once frozen, the vacuum pump automatically turns on and creates a powerful vacuum around the food.
- Drying (sublimation) Phase: The trays gradually warm while the food is still frozen causing a process called sublimation to occur which removes water from the food and allows it to keep its original shape, flavor, and nutrition
How long does it take to freeze dry?
Typically, the amount of time that it takes to freeze-dry one batch is between 20 to 40 hours. Very dense foods and foods high in sugar take longer: fresh pineapple for example can take over 45 hours. However, placing food on the trays and freezing them in your freezer can cut the time down by several hours. The freeze dryer is equipped with sensors that sense when the food is completely dry and alert you when the process is complete.
How Much Does a Machine Cost?
A new home freeze dryer cost ranges from $2,495 – $5,090 depending on the size and type of pump (types of pumps include: oil, premier, or oil-free). Additionally, the ongoing cost of supplies and running the freeze dryer can cost as much as $30 – $40 a month. The original cost includes the freeze dryer, vacuum pump (oil-free pumps are available), vacuum pump oil, oil filter, trays, mylar bags, oxygen absorbers, impulse sealer, and guide to freeze-drying.
See the below table for a detailed cost breakdown:
|Freeze Dryer Size||Cost (standard oil pump)||Cost (Premier grade oil pump)||Cost (Oil-free Pump)||Batch Size||Dimensions|
|Small||$2,195||$2,495||$3,890||4-7 pounds per batch||16.5″ W x 18.5″ D x 25″ H|
Weighs 61 pounds
|Medium||$2,695||$3,195||$4,690||7-10 pounds per batch||18″ W x 21.25″ D x 28.5″ H|
Weighs 112 pounds
|Large||$3,395||$3,895||$5,090||12-16 pounds per batch||20.25″ W x 23.75″ D x 30.75″ H|
Weighs 138 pounds
I own the standard oil pump and it works great but can be annoying having to deal with changing or filtering the oil. My brother owns the oil-free pump so he doesn’t have to deal with changing the oil. If your budget permits, buying the oil-free pump can be worth the extra cost in convenience.

Ongoing Costs of Owning a Home Freeze Dryer
Supplies (Mylar Bags and Vacuum Pump Oil)
The cost for 60 mylar 1-gallon bags with 60 300 cc oxidizer packets is $29.99 on Amazon (June 2021). The oxidizer packets are for one-time use, although the mylar bags could possibly be cut down and reused.
The cost of vacuum pump oil starts at $10 a gallon on Amazon, although that oil can be filtered and reused.
*Pro Tip – to save money on vacuum pump oil I will drain the oil after every 4-5 batches that I run in the freeze dryer and use paper coffee filters to filter the oil and then reuse the same oil in the vacuum pump.
Do Freeze Dryers Use a Lot of Electricity? What’s the Cost?
After breaking down my electric bill and the bill of other family members that have their own freeze dryers I found that electricity costs for me, my parents, and my brother to run our own freeze dryers have consistently been between $10 – $20 dollars a month on average (roughly $1 – $3 a batch). We all live in different states in the Midwest and see similar electricity bills.
Other reports on electricity costs have varied. One person who lives on the East Coast reported that her electricity bill increased $20 – $30 a month during her heavy usage time.
Electricity Bill Calculator for Freeze dryers
Calculate the cost to run a freeze dryer in your home using wattage and kilowatt-hours (kWh) in the below calculator. Search/Google for ‘cost per kilowatt-hour in my area’ or investigate your electricity bill to determine your current electricity cost per kilowatt-hour(kWh) in cents.
Are freeze dryers expensive to run?
Freeze dryers are more expensive to run compared to many common household appliances such as refrigerators, toasters, TVs, smaller microwaves, Dehydrators, and other smaller appliances. However, freeze dryers are roughly just as expensive to run as some larger home appliances including many washing machines, dishwashers, and larger microwaves.
|Home Appliance||Average Wattage||Cost to Run|
Compared to Freeze Dryer
|Freeze Dryer (Small-Large)||990 – 1500 watts(W)||Comparable|
|Microwave||600 – 1200 watts(W)||Cheaper or Comparable|
|Refrigerator||350 – 780 watts(W)||Cheaper|
|Washing Machine||400 – 1300 watts(W)||Cheaper or Comparable|
|Dishwasher||1200 – 2400 watts(W)||Comparable or Expensive|
|Dehydrator||450 – 750 watts(W)||Cheaper|
*Pro Tip – Placing food on the trays and freezing it before running a cycle in the freeze dryer is often better because it allows the freeze-drying process to be more efficient, saving time and electricity that is consumed at a higher rate by the freeze dryer.
Is Buying a Freeze Dryer Worth it?
Buying a freeze dryer is worth the cost for anyone who wants to preserve a wide variety of shelf-stable foods, especially in large quantities, and desires to store those foods long-term in airtight mylar bags or containers outside of a fridge or freezer. Freeze-drying preserves flavor, freshness, and retains 97% of its nutritional value for up to 25 years therefore well worth the cost if used regularly.
A home freeze dryer IS worth it for you if:
- You’re interested in preserving your own food with a 25-year + shelf life
- You want to have a reserve food supply that you can use that still tastes good (similar to when it was fresh)
- You want to preserve food that keeps about 97% of its original nutritional value
- You have the available funds to invest in food storage, backpacking meals, snacks, and more
- You have space to store freeze-dried food in your pantry, closet, cold storage, garage, or other areas
- You want to have shelf-stable food that can last up to 25 years or longer
- You want to store leftover meals for longer
A home freeze Dryer may NOT be worth it for you if:
- You don’t plan on using it regularly
- You don’t have any room to store extra food
- You don’t have enough room to store the freeze dryer
- You don’t have access to fresh produce and other foods
- You have to go into debt to buy one
Check out Harvest Right’s website to see which home freeze dryer is right for you.
If you are unsure about buying your own freeze dryer, try buying packages of freeze-dried food from a food storage company. Check out our article and list of the best foods for long-term storage that includes freeze-dried items. Also, use our free food storage calculator to determine how much food you should store to feed yourself and your family.
Is a freeze dryer loud? if so how loud? A freeze dryer is loudest when the vacuum pump is running and at its peak noise level reaches 62 to 67 decibels. To put it in perspective, a typical vacuum cleaner is about 70 decibels loud so a freeze dryer is slightly less loud than a vacuum cleaner. I have a brother that owns an oil-free vacuum pump and it is slightly louder than my standard oil vacuum pump.
Will Freeze Drying Enough Food Make it Worth the Cost?
Although difficult, I compared the cost of over 20 freeze-dried foods sold by food storage companies to the cost of buying the same non-freeze-dried product from the grocery store also adding in the cost of the freeze drier plus mylar bags, and found that with at least 5 batches a month you’d be saving on average about one third the cost. See the example of freeze-dried strawberries below.
Fresh strawberries 16 ounces (1lbs) from Walmart = $2.98
Small Harvest Right Freeze Dryer (lasting 10 years) $2,195 / 120 months = $18.30 per month / 5 batches per month = $3.66 per batch
50 1 gallon mylar bags on Amazon – 17.99 / 50 bags = $0.36 per bag
Total for 16 oz freeze-dried strawberries using a home freeze dryer = $7
Compared to buying freeze dried strawberries from a food storage company
Augason Farms 6.4 oz freeze-dried strawberries on Amazon – $23
Of course, this isn’t 100% accurate because there are added costs of owning your own freeze dryer such as electricity to run it and oil for the vacuum pump but these costs can be mitigated and are fairly inconsequential. Additionally, more than 1 pound of strawberries can fit in the home freeze dryer at a time which will give you a greater benefit to add to the cost of the freeze dryer. Also, you generally get more fresh foods in one purchase than you would from the company that sells freeze-dried foods.

Even though I own a home freeze dryer I still find it helpful to buy some freeze dried foods and full meals to add to my food storage. I have spent hours compiling a list of my favorite freeze dried foods that are available from reputable companies. Check out my article Best Freeze Dried Foods: Must-Haves For Any Circumstance.
- Preserve and store more food items – Freeze-drying works great for fruits and vegetables, but unlike other food preservation options, it also preserves meat, fish, dairy, eggs, candy, skittles, ice cream, and even fully-cooked meals. To see a more comprehensive list see my article What Foods Can and Cannot be Freeze-Dried: Complete Guide.
- Longer shelf life – Freeze-drying food can be stored at room temperature in a sealed mylar bag, jar, or food-grade bucket for up to 25 years.
- Nutritional value – Freeze-dried foods maintain 97% of their nutritional value. Other food preservation methods, such as canning and dehydrating, will use higher temperatures that degrade the nutrition of the food. See our article Is Freeze Dried Food Healthy? An Expert Weighs In.
- Simple and easy preparation
- Taste – Freeze-dried foods rehydrate more fully than dehydrated products, so the taste and texture are closer to fresh with a freeze-dried product than with a dehydrated product. This also means that you can use freeze-dried foods as ingredients in your everyday cooking and rehydrate the food with excellent results.
- Freeze-drying candy including skittles, gummy bears, and much more. However, pure chocolate, honey, syrup, and jam don’t freeze dry well.
- Save money over time – The more you freeze-dry the more you’ll save. Beneficial to those who love to backpack, hike, camp, and have an emergency food storage.
See current freeze dryer deals on Harvest Right’s website
As you accumulate freeze dried food it is important to know the shelf life of different foods and how to store them to get the longest shelf life. See our article How to Store Freeze Dried Food: Extending Its Shelf Life.
- Cost of the machine – It is expensive to get started because the freeze dryer’s entry-level price starts at over $2,000. This creates a roadblock for many who otherwise are interested in using this method to preserve food.
- Size of the machine – Freeze dryers are not small machines, so it is critical to check the dimensions to make sure that it will fit well in the place that you’d like to store and run it.
- Noise level – Freeze dryers are loud (almost as loud as vacuum cleaners) so they may not work in your current living space.
- The temperature of storage and heat put off by the machine – Freeze dryers, like most machines, work best in ambient temperatures of 45 degrees to 80 degrees Fahrenheit The pump throws out heat, so it is important to put the machine in an area where there is plenty of ventilation
- Slow process – Typical batch time is between 20 to 36 hours so it is a slow process.
How Long do Freeze Dryers Last?
My freeze drier has lasted for over 5 years with no problems and still runs as expected. Harvest Right freeze dryers come with a one-year full warranty for buys in the United States and 3-year limited warranty. See more about their warranties on their website.
Is Freeze Drying Food Safe?
Freeze-drying food is safe as long as the two sub-processes of freezing and vacuum drying are done correctly so that the freezing process is complete within 1-4 hours and the vacuum process leaves only residual moisture.
To test for appropriate moisture levels your food should be dried to a “crisp” or “breakable” texture, however, fruits and other foods that are higher in sugar may be flexible but shouldn’t be sticky.
It is also critical to employ proper food handling techniques while preparing the food before freeze-drying and storing afterward in an airtight mylar bag, jar, or food-grade container.
Does Freeze Drying Food Kill Bacteria? Freeze-drying food does not kill bacteria. Freeze-drying is not a food safety process so bacteria and other microorganisms can stay viable and dormant even after being freeze-dried. Before freeze-drying your food you will need to prepare your food by following proper cleaning and handling.
When home freeze-drying raw foods the bacteria on the raw foods will remain alive, then activate upon rehydration. Food items that are cooked before eating must also be cooked before eating as freeze-dried food. Examples include raw meats, raw eggs, and foods containing raw ingredients.
