How Freeze Drying Works

Learn more about how freeze drying works with a Harvest Right Freeze Dryer. Freeze drying food in a Harvest Right Freeze Dryer is the very best way to preserve food, create an emergency food supply, make healthy snacks, and make great camping and backpacking meals.

Preserve your garden produce, create the perfect emergency food supply, make camping meals and healthy snacks. Unlike other methods of food preservation, freeze drying does not shrink or toughen the food, and retains flavor, color, and nutrition.

Harvest Right freeze dryers produce food that looks and tastes better than store-bought freeze dried food. Experience the Harvest Right difference!

Refrigerated, frozen, and canned food just don’t last very long. Freeze dried food will last up to 25 years and does not need to be to be rotated like other foods. Freeze dried food is perfect for home storage.

Freeze drying maintains 97% of the nutritional value of the food. Other methods of preservation, such as canning and dehydrating, use high temperatures that destroy much of the food value.

Freeze drying works great for fruits and vegetables, but unlike other options, it also perfectly preserves meat, fish, dairy, eggs, ice cream, and even fully-cooked meals.

If you can press a button, you can freeze dry! Simply press start on the touch screen, and the patented Smart Freeze© technology senses when it’s done. Everything is automatic.

Not only will the food you freeze dry at home look and taste better than store-bought, it’s much less expensive! Freeze dry all of your leftover meals, and you’ll save even more money.

I asked my self how freeze drying works, found 41 second video that answered my question. Living in the future is pretty cool sometimes.

Ok, now I can finally freeze dry my ice cubes

Bless the soul who did not waste any additional second than necessary to explain the concept.

FOR CONFUSED PEOPLE: The point of water turning into steam depends on pressure and temperature. So the lower pressure, the faster water turn into steam. So you freeze it very much so food doesnt rip apart from water kinetic energy.

For example water in vacuum is "boiling" at +_ 20°C because the less pressure from air, the bigger is free space for water electrons to release their kinetic energy from rotation around atom.

Well explained in simple terms. However the time to freeze dry cannot be taken literally as industrial freeze dryers operate at different level of efficiency.

I had a question, less than a minute after I know the answer 👌🏾

So it’s like putting food in space (vaccume and cold)

Well explained. Even me, someone with a highschool level physics education understood it perfectly.

I love that if I have a question, youtube supplies the answer.

Not related to this video technically, but sometimes the answer is better off not learning...

Please give me one! I'm too poor to afford it but been wanting your brand for years.

This will be the new dishwasher for sure.

Finally, I've seen hundreds of videos and never knew what was happening

There are 'Coghill Farm' videos that anyone can find online, and they have one of these. They use it all the time for their home- grown produce and always demonstrate the 'before, during, and afterwards'. They show you everything and how to re-constitute the food afterwards. I would love one myself but I don, t know if they can be obtained in New Zealand.

I purchased the XL freeze dryer I have been working with someone from harvest right but nobody is able to come out and physically look at my freeze dryer. The back of the drum where the drain is located is almost 2 inches taller than the front of the drum where the door is located so it does not drain it keeps turning off And won't turn back on unless I unplug it and plug it back in I already have over an inch of shims under the machine's feet and I have to put shims in the drum to level out the trays so I can put any liquid in there without it pouring out because it is so off and the technician told me that it's normal and it was designed to be 2 inches higher In the back to help it drain But it's really only is draining out of the door. She informed me today she's closing my ticket because there's nothing mechanically wrong with it even though it's shutting off in the middle of cycles. She suggested that I put shims under the machine and just pre freeze the food So I can use the trays at full capacity because i can only get about 5 to 6 cups in the trays before it will pore out the front. Any help would be appreciated

Whats the refrigeration system that cools this? Is it a cascade system?

[readysetprepare]

Can you ship world wide? Or can you send in multiple shipments my APO only allows up to 70 lbs.

How much power it needs for this to work thinking of grid how many watts a hour

[shyamcech]

@harvest right team: Have you guys freeze dried Coffee concentrate into instant coffee using your driers???

[ANATURALDREWSASTER]

I really hope one day you integrate a magnetron to drastically reduce cycle times, and due to ice having lower absorption rates than liquid water it would evenly heat the food as well. Even a low power microwave system of a few hundred Watts would blow the pad heaters away I think.

Después de usarla en candy mode ya no pasa de freeze tengo que hacerlo manual me pueden ayudar
