How to Make Beef Jerky in a Freeze Dryer

Freezing dry food is a recent invention and many people discover its usefulness. What it means is that every bit you freeze dry out your food all moisture and water content is removed from the food. This is different from traditional freezing. With this new method, the nutritional value of the nutrient remains intact. This is exactly what you desire when you go camping for days or are blocked from the globe for a calendar week or more during a disaster event. Yous need nutrition more than always. Otherwise, the structure of the food changes drastically since it turns into hard crumbs.

Yous will demand warm h2o to united nations-freeze and un-dry the food so it becomes edible. There are a few steps to follow for proper freeze-drying, and we will discuss in this article.

You lot should too know that foods with high content of water are the easiest to freeze-dry. Such foods are fruits and vegetables, e.grand. apples, pears, berries, even potatoes, carrots and peppers. Their structure remains intact, and merely the water content is removed. Interesting plenty y'all tin can freeze-dry out other food like meat, pasta, oats, etc. Your imagination is your limit. Commencement you will have to larn the method using fruits or vegetables, since it's easier with them. When you get comfortable with the procedure, then you can motion to other, more complicated, foods.

You demand to exist enlightened about freeze-drying meat though. Don't do this procedure when you've just kept the meat in the freezer and removed information technology from there, or subsequently yous bought it from the market. Meat must be freeze-dried right after cooking. This is when all its properties are intact and it will all the same exist edible. If yous freeze-dry raw meat, and so later on months yous decide to eat information technology and melt information technology, it will still be raw. And be sure that raw meat is inappreciably appetizing.

Now, if dry out freezing seems a flake also complicated, at that place is always the pick of ownership specially designed repast packages. Nosotros plant some great options on Nomad Nutrition, an emergency food supplier for preppers all over the earth. We reached out to them and got you x% off on all orders (even when you re-order). Just add the SRVMA10 code when y'all checkout.

The all-time way to freeze dry your food

Showtime of all, you don't need some super advanced technique to achieve these results. Information technology is true that there are special vacuum machines which suck out all moisture from the food (and that happens pretty apace), merely that's non a must. There are other ways to end upwardly with freeze dried nutrient.

Use the freezer! This is an easy way to have freeze dried food. The procedure may have several weeks, but there'south no more action on your part than only placing the food in the freezer and allow it work. Basically, you lot can chop the food to small pieces and place them on a perforated tray or similar (so there's equally little surface covering the nutrient as possible).

During the first several hours the nutrient volition freeze. Then starts the sublimation process (pregnant, the drying process). This takes much longer – from one to several weeks. You tin test if the nutrient is ready, by taking a frozen piece from the freezer and permit it melt. If information technology turns blackness and then it'southward not ready and you need to let it dry more. When the food is fully dried it shouldn't alter its color (especially to black).

If the food doesn't turn black after melting and keeps its original and natural color, then you're ready for the final step of storing information technology.

Another way to freeze dry out food is to employ dry out ice (CO₂). This procedure is similar in concept to the to a higher place method. You can simply use difference means to attain what yous want. Basically, dry water ice lets all moisture evaporate from the nutrient, leaving it freeze-stale. In extremely cold environments there's nigh nada humidity in the atmosphere (equally a reference, Antarctica has the driest conditions on Earth).

You will need a very big container, almost twice equally the food you lot will freeze dry out. Place the nutrient in large plastic bags and seal them (no dry ice should be able to penetrate the package). Cover the food entirely with the dry out ice.

So identify the container in the freezer. The container needs to accept a few holes so that the gas and wet can escape the container. If at that place's no more than dry out ice inside the container, then this is your sign that the nutrient is ready. This should happen with 24 hours so brand sure to bank check regularly.

A word of circumspection – when you lot practise the higher up, ever wear gloves and protective wear while you handle the dry ice.

You will need to store the food when it'south prepare and freeze-stale. The all-time way is to proceed it in plastic bags, just make sure to push the air out, since it contains moisture. You don't want to keep moisture closed within with the food. This volition speed up the spoiling of the food. You lot tin can use a vacuum packing car if yous want to be meticulous. You also should exist able to properly seal the numberless, so that y'all'll be sure that no wet can discover its manner within.

Another popular method is to apply a special vacuum chamber but you'll accept to buy 1 if y'all desire to use this method.

Get-go of all, freeze the nutrient in the freezer (a deep freezer would be even meliorate) and make sure that at that place is no other food inside – go along only the food you desire to freeze-dry later. Let it stay for several hours. Avert opening the freezer too often since that will tiresome the procedure, as ice crystals form very rapidly when frozen air meats moist warm air.

When that'south done, remove the frozen food, and immediately identify it in the vacuum chamber. Set it to 120 m Torr. The temperature must be 10 o C (50 o F). Again the procedure should take at a minimum i calendar week, maximum a few more. It all depends on the parameters and how much moisture is in the food. When the sublimation is finished, identify the nutrient in storage bags and seal them well.

Then comes the moment when nosotros need to instruct you how to reconstitute your freeze dried food. This process is maybe the easiest of all. You need boiling water (a cup or two) and add together it to the nutrient. Information technology will quickly outset turning to its original fresh form, since information technology soaks with all the wet you removed by following one of the higher up methods.

A few more details and information about freeze dried food

These details may exist of interest to y'all. When you first freeze the nutrient, it requires a temperature of about -18 o C (-0.4 south F). And then, in order to make the sublimation procedure happen, contrary to obvious logic, a warm temperature is needed – it gives free energy so that this process tin can be started. The ice crystals need to evaporate, and so a temperature of 35 o C (95 o F) is needed for this.

As well, while drying in the vacuum container, very low pressure is used. It is needed so that water almost immediately turns from 1 state (frozen or liquid) to another (gas), and thus evaporates very chop-chop from the food. Without this process drying would take much longer in normal conditions.

Of course in the traditional method (without using whatever fancy machines), freezing the food basically makes vacuum to exist created around the h2o molecules. When the food is slightly warmed (for drying) these ice crystals rapidly turn to vapor and exit the surface of the food.

Some other interesting fact is that water has only 2 atmospheric condition when put in a vacuum bedchamber (or in any vacuum condition) – it can exist either gas or a solid. Every bit the nutrient is frozen (vacuum created), and then moved to a slightly warmer condition, the frozen h2o tin can only evaporate as a gas. The affair is that fifty-fifty if the food is not kept in super depression freezing temperatures, information technology even so remains in sub-zip condition. That is the key to keeping information technology frozen, nevertheless letting the h2o evaporate. This process is the so-called sublimation we mentioned to a higher place.

In fact if y'all use the commencement method we described higher up, you lot won't need annihilation special than only a freezer. The first stage is the freezing. Then the water transitions to the 2d vapor status and begins evaporating. All the other methods require special chambers or dry ice in gild for these two conditions to transition 1 from the other. As long as y'all know how water works, yous should be able to control the procedure meliorate.

Also, any type of food can be freeze-dried and you don't have to worry about the sense of taste or the smell later on information technology is reconstituted. Information technology is even believed that reconstituted freeze-dried food tastes and smells fifty-fifty improve than traditionally stale food. The freeze drying process is the one that preserves all the qualities and nutrients in the food. Calculation the humid water simply revives the food. The only nutrients that can be depleted somewhat are vitamins C and East, and folic acid. Some corporeality remains, but near of it can't withstand this procedure. That'due south why is of import to include high-calorie foods in your freezing process. If you don't know which ones to cull, nosotros have a great list in our article on high-calorie vegetables.

Freeze stale food can last for years. In that location are people and even markets that store food in this way so it can remain almost untouched by time and so be reconstituted when information technology needs to be eater or sold. This process is in fact very old and is being used by the Incas. They placed a piece of nutrient during the night to freeze so keep information technology in the hot lord's day for a whole day to dry out completely.

Freeze drying is besides popular among hikers and campers since camping requires that you carry a lot of things in your haversack. Nutrient can have a lot of space and make your haversack pretty heavy. If y'all add a few bottles of h2o and your main weight comes from nutrient and h2o. So, substituting traditional nutrient with freeze dried nutrient is really a great way to savor a week or so of trekking or camping without the burdens of heavy weight.

It is also highly advisable that everyone has at to the lowest degree one-year of food stored for some future disasters or economical crises. After all yous tin't keep a mere basement with fresh canned nutrient, since it may non all fit in. Hither comes the magic of freeze dried food. Since 98% of the moisture in the food is removed, this would also mean that more than ninety% of the food's volume will be removed besides. This makes information technology cracking for long-term storing (away from moisture), since it takes very footling space. If you lot want to know more almost storing nutrient, have a expect at our article on emergency food storage.

If you don't take the want to freeze dry out your own food you can plow to manufacturers who already sell such food. One such pop brand is Mountain Firm. It is peculiarly popular among tourists and campers, but if yous need to store food you can buy in bulk from them. And don't expect that they sell only some bleak freeze dried fruits.

On the contrary, they have whole meals like lasagna, scrambled eggs, cottage cheese and almost everything yous can call back of. The truth is that almost any type of food tin can be freeze-dried. Some people even freeze dried ice foam. And to our surprise it worked.

This is why if y'all accept your time and effort one of the above methods yous can employ your own imagination and freeze dry your favorite meals, instead of eating meals yous don't peculiarly bask.

And finally, you lot tin freeze dry meat. One very popular such food is beef jerky. The process is the same and yous end up with meat, packed with all its inherent nutrients and is so lightweight that information technology's like a newspaper sheet. You can too practise the same with regular cooked beef. So, cook the meat, and so chop it to small pieces. Follow ane of the higher up methods for freeze drying and yous will end up with very minor hard crumbs (nigh similar bread crumbs). It wouldn't even look like beefiness, simply when you add boiled water you lot will recognize the gustation immediately.

Consider freeze drying whenever yous become camping ground or want to shop some food for more uncertain days, or just experiment and run across how like shooting fish in a barrel information technology is to complete the process. It'due south great to take less room to spare in the fridge when you need to store your food.
