Learn more by going to harvestright.com/
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.
I still don't feel like the question was answered though. Why would the water leave the container if it's frozen? The unit doesn't get warm enough for the water to melt.
@@FraterAleph sublimation converts ice water to water vapor and occurs only under low pressures
@@PalCan That still doesn't answer his question.
@@PhantomOSX it creates a vacuum which will force all the water molecules in the food to evaporate. It'd be better to just learn how a vacuum chamber works since its basically the same thing
So we all do this 😂😂😂
This was simplier than expected
The cold trap is the difficult part
Yea simple...
simple yet complex, the duality of man
Ok, now I can finally freeze dry my ice cubes
Now that what we call dry ice
😂 dehydrated water.
Directions : just add water
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.
now i get it. Thank you for real
Bless the soul who did not waste any additional second than necessary to explain the concept.
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.
Freeze dryers(driers) that are readily available for the average Joe, it was stated in the video up to 36 hours to completion, just wondering if these machines consume a lot of energy?
not if you live somewhere cold!@@ShowemRight
Thank you for your on point video
So it’s like putting food in space (vaccume and cold)
may the force be with you always
I had a question, less than a minute after I know the answer 👌🏾
Please give me one! I'm too poor to afford it but been wanting your brand for years.
Well explained. Even me , someone with a highschool level physics education understood it perfectly.
Gotta appreciate that
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...
Wish I could buy this in europe
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?
This will be the new dishwasher for sure.
@harvest right team: Have you guys freeze dried Coffee concentrate into instant coffee using your driers???
From where I can get it?!
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.
Interesting af
Can you ship world wide? Or can you send in multiple shipments my APO only allows up to 70 lbs.
Después de usarla en candy mode ya no pasa de freeze tengo que hacerlo manual me pueden ayudar
How much is the machine?
Finally, I've seen hundreds of videos and never knew what was happening
How does it get that cold? Does it use liquid nitrogen if how would a home replace or get liquid nitrogen for machine 🤔
Here due the Canadian prepper
Excuse me.. can i have your video for my presentation? I will cite your channel😊thank you
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.
What makes you think it would do so? Can you give a link?
@@aerobyrdable there are numerous research papers on the subject, I would worry that the vacuum pump would not be able to keep up. It would drastically complicate the design, you'd have to worry a lot more about the chamber design.
@@ANATURALDREWSASTER glancing around, the papers Ive seen list something like a 20% reduction. Far from nothing, but not exactly miraculous.
@@aerobyrdable I think the biggest advantage would be materials that aren't very thermally conductive once the moisture from the outer parts of the material is removed, the microwaves allow penetration deeper into the material allowing a more thorough drying of thicker, denser materials. But also from what I read voltage levels per area must be kept low to prevent plasma from forming and damaging the material.
@@ANATURALDREWSASTER Yup. That corona'll getcha every time XD.
How much power it needs for this to work thinking of grid how many watts a hour
About as much as a window air conditioner.
Does the -40 degree temp have to be maintained during the process or just initially?
Once the temp reaches -40, the vacuum pump has to be maintained between 24-36 hours.
@@chasedownblocks1736 👍
Not sure when the heat kicks in, but my vacuum is on and is 133 degrees in the chamber now. Thick ice on the walls. This runs is about complete.
display is not working in the freeze dyer..
Smart sensors = Humidity sensor?
Where can I get a price list for this equipment. I need 40 units.
I am a freeze-drying machine company in China, I see you are interested in machines, can you give me your WhatsApp number?
Anybody here know the contact of harvest sales?
Can I use the Pharmaceutical Freeze Dryer to dry foods like fruits, veggies and prepped meals?
We are doing strawberries and limes as we speak....... we adjusted only the shelf temp up to 100*. So far so good :) We have a home unit that HR sent us the Pharmaceutical software for so our shelves are a bit larger but less of them.
@@twoweedos8119 whats the main difference between the two software? and thank you!
@@millaezman8984 Honestly we are very new to this. We bought our medium home unit for food and hash. It appears that the pharma just gives you more control. (like dropping shelf temp down lower) This is good but we also find it a little challenging to figure out exactly what setting work for different things.
Wouldn't the microwaves cook the food?? This process works because the ice turn into vapor and not water due to the vacuum... correct?
Exacly, at very low pressure the water turns directly from ice to vapor. this trasformation is called sublimation.
No microvave involved! Only vacuum
I want of you freeze dryers
How it differs from food 0:17 dehydrator?
It keeps more nutrition than dehydration
If only somebody could find a way to do it more affordably. 2 grand for a machine is rough
Sounds like it used a lot of energy.
But it doesn’t address that bacteria is not killed.. so im still uncertain
Price???
Expensive under $2000-$5000+
How many kWh per batch?
Good question
1800 watt for 30 hours. Do the math based on electricity cost in your area
do freeze drying kill bacteria in the food?
According to their site it does not.
I think this is what happens when you get trapped out in space
OMG, 24...hours!
How much temperature brother
2.1 mil views and only 1.9k likes damn
ok
It’s 5am. What am I doing here? I should be sleeping
Where is the water trap chamber (Ice condenser) ???
I was wondering the same thing, I am confused. where goes the water extracted from food?
I just skim watched a RUclips on this by Living Traditions, looks like there's a valve in bottom left side corner, I assume you'd need to drain the water into a pan or something
@@andyandy4459 Thank you, but from what I know, that valve is used to drain liquid water.. water vapor needs first to be condensed by a condenser that transforms it into ice. Then, after we finish and stop the machine, the ice is scraped off the condenser (or heated to become water that is drained through a valve like here). So the draining valve is opened AFTER we finish the cycle.. There must be an ice condenser inside!
@@yeseenmeshleeah7359 is it possible to install water separator between vaccum pump and chamber?
@@kumaresant42 My question also.
Is the power outlet 220v or 110v?
110v. But the large model requires a dedicated 20a circuit.
You need to give a better explanation of your product. While I enjoy the part you say it drops to negative 40* what with the heat it gets up to to kill bacteria?
I know the process can kill it and make it a TCS product but I need your explanation on the way your product work and heats up to kill the bacteria.
I have seen your machine reach temperatures of over 150* which is the temperatures required for killing bacteria
I came here after watching a video about freeze drying pets to preserve the bodies.
Zero Fahrenheit is -17 degrees Celsius. Attention: the rest of the world!
🤬🤬BRAND NEW $3,000 machine has been JUNK from the beginning and after 5 weeks I STILL don’t have help! They ignore emails and calls, and put you into a non ending cycle of repairing things YOURSELF! A brand new machine should not need repair! So I am unable to use this machine and they REFUSE to exchange it for me!
They expect you to be your own repair person and will not (rarely) reply to messages or emails. Customer service is nonexistent 🤬
hope your problem get soved. dont forget to update here
And not that simple
Any body using harvest right freeze drier ?
somstt I bought one this year. The results so far with strawberries, pineapples, grapes, apples, fruit smoothie mixes, onions, peppers and eggs are amazing. This machine is well worth the price especially as we head into the second Great Depression i.m.o. Having the ability to begin building a long term pantry while food prices are low is priceless.
@@gonewplaces2685 whats the purpose of this machine?
@@sayonara9633 to preserve food long term.
so basically i gotta wait a day. lame

This video is worthless.
Praise the LORD for creating dust!
What does this mean?
@@cappyjones I believe that our substance is dust. I believe that you can mill grains like wheat, and oat to make dust. Likewise, you can freeze dry apples to make apple chips.
Do you believe in JESUS? I believe in JESUS!
