Freeze dryers for food production
For farms, food brands, meal makers and pet-treat businesses drying fruit, vegetables, meals and meat. With wet food, the cold trap sets the batch and the cycle runs for days, so plan around both before you choose a machine.
Who uses them, and for what
- Farms and orchards turning seconds and surplus into shelf-stable product they can sell all year at markets, online or in the farm shop.
- Food brands making freeze-dried fruit, powders and inclusions for baking, cereal, smoothie and snack lines, often to develop a product before handing volume to a co-packer.
- Meal makers producing camping, backpacking and emergency meals.
- Restaurants, bakeries and bars making garnishes, fruit powders and freeze-dried inclusions in-house.
- Pet-treat makers drying single-ingredient meat and organ treats, which come under feed rules rather than food rules; more on that below.
Our machines don’t carry NSF or UL certification. Many customers run them in commercial settings, but requirements differ by city, county and product, so ask your inspector what your kitchen or facility needs before you buy.
The cold trap sets the batch
Every pound of water in the load has to freeze onto the cold trap, and the trap holds a fixed amount of ice. So the most fresh food you can load is the lesser of the published batch maximum and the ice capacity divided by the food’s water content.
| Most you can load | Ice capacity | Strawberries (91% water) | Apples (86%) | Cooked meals (70%) |
|---|---|---|---|---|
| 5- or 7-Shelf | 14 lb | 15 lb | 16 lb | 18 lb |
| Large | 25 lb | 27 lb | 29 lb | 35 lb |
| Mega | 40 lb | 44 lb | 46 lb | 50 lb |
A load near 80% of the machine’s capacity counts as large and gets a longer final dry, so most producers run a little under the maximum.
What each machine makes in a week
With wet food, cycle time sets output more than batch size does. The figures below are full loads on a machine running around the clock, with two hours between batches to defrost, clean and reload. Drying time uses the middle of the published range: 16 to 30 hours for 8 lb on the 5- and 7-Shelf, 20 to 40 hours for 20 lb on the Large and Mega.
| Product and machine | Fresh per batch | Cycle | Fresh per week | Dry product per week |
|---|---|---|---|---|
| Strawberries, 5- or 7-Shelf | 15 lb | 65 h | 38 lb | 3.5 lb |
| Strawberries, Large | 27 lb | 65 h | 68 lb | 6.3 lb |
| Strawberries, Mega | 43.5 lb | 93 h | 77 lb | 7.1 lb |
| Apples, 5- or 7-Shelf | 16 lb | 66 h | 40 lb | 5.7 lb |
| Apples, Large | 29 lb | 66 h | 72 lb | 10.4 lb |
| Apples, Mega | 46.5 lb | 94 h | 81 lb | 11.7 lb |
| Cooked meals, 5- or 7-Shelf | 16.5 lb | 59 h | 46 lb | 14 lb |
| Cooked meals, Large | 29 lb | 58 h | 82 lb | 25 lb |
| Cooked meals, Mega | 47 lb | 82 h | 94 lb | 29 lb |
Three things move these numbers. Pre-freezing loaded trays in a chest or walk-in freezer cuts each cycle by 5 to 10 hours, which is why spare tray sets and a Tray stacker ($18–$36) are the cheapest throughput you can buy. Sugar adds final-dry time: high-sugar fruit wants a 10-hour final dry whatever the load. And machine count beats chamber size on wet food: the Large and Mega share a published drying rate, so two Larges make about 136 lb of fresh fruit a week to one Mega’s 77, with two independent cycles.

Settings from our own testing
Every machine runs one automatic cycle with four settings you can change per recipe: shelf chill, target vacuum, maximum shelf temperature and final dry time.
| Product | What to change from the defaults |
|---|---|
| Most food | Factory defaults: 550 mTorr target vacuum, 120 °F maximum shelf, 7 h final dry, shelf chill to −5 °F |
| Fruit and delicate foods | Shelf chill to −10 °F |
| High-sugar fruit | 350–500 mTorr and a 10 h final dry; watermelon 10 to 15 h |
| Delicate leaves and greens | 50–100 °F maximum shelf, 300–450 mTorr |
| Milk | 500–600 mTorr, 7 h final dry |
| Ice cream | 12 h final dry |
Final dry also scales with the load: 5 hours for a small load, 9 for medium and 12 for large, and when more than one rule applies, use the longest. When you develop a new product: if it shrivels during drying, lower the target vacuum; if it isn’t done, or collapses when the cycle ends, lengthen the final dry; if it’s delicate, thick or high in sugar, lower the shelf chill or dry by the probe. If in doubt, run the defaults and check by weight.
Preparation matters as much as settings. Blanch grapes, which otherwise turn into raisins, and broccoli, which otherwise shrivels. Pierce or slice blueberries and cherries so they don’t burst. Store-bought frozen sliced fruit tends to shrivel, and canned pineapple isn’t ideal. Break the vacuum slowly at the end of every cycle.
Selling it: food and pet-treat rules
Food for people. What you can sell is set by your state, and freeze-dried candy, produce and meat are treated very differently. Candy is often allowed under cottage food rules; fruit and vegetables depend on the state; meat sold commercially has to be inspected under the Federal Meat Inspection Act, which no cottage food law gets around. Our state-by-state guide has the agency sources for nine states.
Pet treats. These are regulated as commercial feed by your state department of agriculture, not under cottage food law, and most states want a license before you sell. Indiana, for example, requires a commercial feed license from every seller regardless of size, $50 a year, plus a $50 listing for each product sold in packages of 10 lb or less. Missouri requires a commercial feed license from anyone who makes, distributes or labels pet food or treats in or into the state. Minnesota’s cottage food registration covers certain baked or dehydrated cat and dog treats, and everything else needs a commercial feed license. New York requires in-state makers of freeze-dried meat or poultry treats to follow a scheduled process from a recognized process authority. AAFCO lists every state’s feed control official.
Freeze-drying is not a kill step. It removes water; it doesn’t reliably kill bacteria. Raw meat and organ treats need a validated way of controlling pathogens that your regulator accepts. Our food safety reference covers this in more depth.
Packaging. Every commercial configuration ships with mylar bags, oxygen absorbers and an impulse sealer. Check your state’s packaging rules before you use the absorbers: Ohio, for one, doesn’t allow cottage foods in reduced oxygen packaging. These are summaries, not legal advice; confirm with your state agriculture department and county health department before you sell.
Which machine, by weekly volume
| Fresh product a week | Setup | Machine cost |
|---|---|---|
| Up to about 40 lb | 5-Shelf Commercial | $3,360 |
| About 40 to 80 lb | Large, or the Mega for bulky, low-moisture loads | $4,335 or $5,355 |
| About 80 to 160 lb | Two Larges | $8,670 |
| More than that | Add machines; past several hundred pounds a week, look at production equipment | Ask for a quote |
Volumes assume fruit-like water content and a machine running around the clock. Cooked meals and meat dry out faster per pound, so the same machine handles about 20% more of them. For when a bank of shelf machines stops making sense, see industrial freeze dryers.
Quick answers
What’s the best commercial freeze dryer for fruit?
For output per dollar on wet fruit, the Large: it holds about 27 lb of strawberries per load and turns about two and a half batches a week. The Mega takes bigger loads but runs longer cycles, so it makes only about 13% more fruit a week for $1,020 more.
Can I freeze-dry raw meat to sell?
For people, meat sold commercially needs federal or equivalent state inspection. For pets, you need your state’s commercial feed license, and some states set process requirements for freeze-dried meat treats. In both cases freeze-drying itself isn’t a kill step.
How much electricity does a production batch use?
A full load of fruit uses roughly 58 kWh on a 5-Shelf, 72 kWh on a Large and 120 kWh on a Mega, about $10, $13 and $22 at the 2026 US household average of 18.2¢ per kWh.
Do the machines need a commercial kitchen?
The machines don’t; your product and your state decide. Some states let you make certain products at home, others require a licensed kitchen, and a few treat large freeze dryers as commercial equipment that disqualifies a home kitchen.
