One that involves 3 main steps:
* Freezing
* Lowering pressure
* Removing the moisture through sublimation
The end product is completely different than "dehydrated" foods. Because of this complexity, it takes dedicated, high-tech equipment to freeze dry food. Like dehydrating, you place food on large open racks to allow for air circulation. But, instead of placing the food in a high temp environment, you load the racks into a vacuum chamber. Then the freeze dryer lowers the temperature inside the vacuum chamber. To an incredible low temp (around -40deg 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. Due to the reduced pressure, the water in the food "sublimes". Sublimation is the process where solid ice changes directly into water vapor without ever becoming liquid. The food gives up its water content without sacrificing texture, flavor, or nutrition.
The benefits of freeze drying
1.More Moisture Removal
One of the main reasons to remove moisture from food is to prevent the spread of mold and bacteria.
All living organisms need moisture to thrive. So by lowering the water contents, it's nearly impossible for them to survive.
Most home dehydrators can remove about 90 to 95 percent of the water contained in foods.
By comparison, freeze drying will remove up to 98 to 99 percent of moisture content.
2. Much Longer Shelf Life
The lower water content of freeze dried foods allows for a much longer shelf life if stored properly. That's why it's considered one of the best non-perishable foods.
Freeze dried meals properly sealed in mylar bags will keep their texture, flavor, and nutritional value up to 25 years (or longer)!
3. Better Nutritional Content
Dehydrating food doesn't change the fiber or iron content. But many of the vitamins and minerals begin to break down at higher temps.
Freeze-dried foods keep more of these valuable vitamins and minerals.
4. More Appealing Appearance & Composition
For most people, the biggest hurdle for dehydrated foods is taste and texture.
Freeze dried foods keep the shape and color of fresh food. You can often rehydrate the food back to a similar original consistency!
For example:
Freeze-dried strawberries become soft again if you add a little water or place them in your mouth.
5. Lower Weight
The greater reduction in water content provides an extra reduction in weight.
This is great when you have to pack your food on your back for miles and every ounce counts!
6. Less Cooking Time & Effort
Freeze-dried foods generally only need the addition of water to reconstitute them. Unlike the slow simmer, you have to do with dehydrated foods.
Depending on what you're preparing, most freeze-dried foods will be ready to eat in less than 5 minutes.
This makes meal prep faster and easier for everyone - especially if backpacking or camping.
1. Is the freeze dryer for home use?
Yes, this is the small scale for personal use or small business.
2. What food can I do freeze drying in daily life?
* Fruits and Veggies
Small fruits and vegetables (blueberries, beans, etc.) can be freeze dried in one piece. But you'll need to cut larger items into
smaller slices or chunks.
* Meats
This same principle also applies to meats. Stewed meats freeze dry well, but large thick steaks are far more challenging.
Cook all meats before drying. The rehydration process may not involve adequate heat to cook it later.
* Coffee
How did you think they fill those packets of instant coffee crystals?
* Meat
Not jerky, but superlight chunks of steak ready to be added to dinner in a flash!
* Fish and Seafood
Freeze dried shrimp feels like they should be fake, but they rehydrate to add to soups and burritos!
* Eggs
Real scrambled eggs on day 9 of a trip? You can do that with freeze-dried egg powder. That's a treat.
* Dairy
Dried milk powder is a staple in some places. This makes it possible to keep a large amount of milk on hand without it spoiling or
taking up the whole fridge.
* Freeze dried butter powder is an amazing find that has made my camp cooking SO much better!
3. What's the warranty?
One year international warranty, lifetime technical support.
4. Are you the factory?
100% real manufacturer with more than 18 years experience, do OEM & ODM for some famous company with more than 10 years
experience, and have countless customer cases.
5. Shall I have the factory visiting?
Sure, welcome any time, video visiting also welcome during the Flu period.
6. What is the delivery time?
In general, regular models are in stock. Multiple warehouses across the country can be shipped at the same time. The sample order
can be sent out within 3~5 days. 5~10sets, can send out in one week. More than 10sets, need around 10~15 working days.
7. Can we put our own logo on the machine?
Sure, we can do OEM for you. ODM also is welcomed
8. Is sample order available?
Yes, samples is available, but the sample cost and postage charge is on buyer's account.
