From David In Israel: How Freeze Drying Works

James:
I am sure the readers are interested in the way that industrial produced freeze dried foods are made. I was a kashrut masgiach (kosher supervisor) at a major freeze dry producer in the United States before I emigrated to Israel. Mashgichim are flown all over the world to places where there is no Jewish community to certify the kosherness of foods for consumption by Jews. (The laws of kashrut are much too complex to describe here). The plant I certified had two major types of chamber one that was bus-sized and another that was the size of a minivan. Trays were fed in by an electrical railroad placed on the floor, hundreds if not thousands of pounds were freeze dried at a time. The chambers start out at below freezing when the vacuum is applied and as the time passes (the program depends on the food) the temperature is raised to (again depending on the food and its temperature tolerance) up to around 150° Fahrenheit. Freeze drying is simply quickly subliming away all of the water, the same thing that happens in freezer burn. Vacuum goes a long way to assist the subliming
process, at a vacuum of 20 mmHg, water will boil at 15°C stay below the boiling temp until almost all of the moisture is gone. Freeze drying keeps the food both feeling and tasting much fresher by maintaining the basic cellular structure of the food just desiccating. A standard food dehydrator which I have used at home radically changes both the mouth feel and flavor not to mention making for high re hydration times, there is also the question of how much nutrient is lost long term due to oxygen exposure. Vacuum pumps are available used for reasonable prices a coop might be able to purchase or build and run a small chamber. If anyone is feeling creative and builds their own freeze dry chamber, please write in with your results.



Letter Re: Canadian Source for Long Term Storage Food?

Hi Jim,
I just recently found your blog and love it! I was hoping you might be able to help me out. I’ve been trying to find Canadian sources for bulk food/storage supplies and had no luck. Do you happen to know of any? Thanks! – Kim

JWR Replies: I don’t know of any major storage food packagers in Canada. Most are just distributors for U.S. packaged storage foods, and they tack on a substantial mark-up. They offer no real value added except for being on the far side of those pesky Customs Canada minions. To minimize shipping costs, you are probably best off ordering directly from a border state, like Idaho. Two firms that I recommend there are Walton Seed and Survival Enterprises. (The latter is one of our advertisers.)



Letter Re: Making Farm Field Water Runoff Water Drinkable

James:

I’ve considered as an emergency water supply the steady runoff from the cornfield behind us. It’s always at least a steady trickle even in the driest part of summer. Will a Katadyn filter or similar remove pesticides or other chemicals from it? Or should I plan on a small water still? – Mike

JWR Replies: If working with field runoff, first use a pre-filter to remove sediment. Just a couple of thicknesses of T-shirts over a five gallon bucket works fine as a pre-filter. Using pre-filtered water will greatly extend the life of your primary filter. Next, to filter out the majority of herbicides and pesticides, you should use a two-stage filter such as a Katadyn Combi Plus filter. These are available from a variety of Internet mail order vendors, such as Dom’s Outfitters. However, keep in mind that if runoff water ever become the your main supply of water in an extended disaster situation, no filter system is 100% effective at removing herbicides and pesticides. For that, you would need either a distillation or reverse osmosis system, which are far more complex and have large power requirements.



Two Letters Re: NiMH Batteries

Jim:

If left idle, a NiMH battery loses up to 1% of its original capacity per day. (This doesn’t mean that it loses 100% in 100 days; rather, it means that after day one, it is at 99%, after day 2, it may be at 98.01%, etc. — it will theoretically never reach 0%)

I bought a Grundig/Eton FRS250 hand crank radio a year ago. I used it every day for about two months and it would run for two or three hours on a two-minute crank. I then left it idle for about 8 months, after which time it would only play for about 10 minutes on a two minute crank. Needless to say, this is highly disappointing and constitutes a major flaw for preparation. (What good is an emergency hand crank radio if it doesn’t work in an emergency?)

To (hopefully) remedy this problem, I recently ordered an adaptor/charger from the manufacturer (Eton). If you hook up the radio to the adaptor/charger and leave it plugged in, it will send a low-voltage trickle charge to the batteries to keep them “topped off.” In theory, this should drastically extend the life of the batteries. Time will tell. If, six months from now, I can get still a few hours of play time on a full crank, then I will conclude that the trickle charger is the best solution to the NiMH problem. (Note that it is possible to “fry” NiMH batteries if the trickle charger is too powerful, so do your homework if you are shopping for one.)

Frankly, as popular as hand crank emergency radios have become, I am surprised that I have never read about this flaw in reviews and discussions. A lot of people who bought these radios and keep ’em in the box are going to be sorely disappointed when the lights go out and discover that their radio doesn’t work because the batteries are nearly dead. (Of course, even if the batteries are dead, the radio will still play if yo u constantly turn the crank, but that doesn’t sound too fun.)

Moral of the story: stock up on alkaline batteries just in case. – J.S. in Virginia

Hi Jim,
Regarding the question on the blog about storing NiMH batteries. Basically they do not store very well. Nor do they seem to last as long as they are advertised to. My company makes industrial equipment that uses small (2 AA cell equivalent capacity) NiMH battery packs. When we first started using them, we believed that they would last for five+ years and hundreds, if not thousands, of charge/discharge cycles. That was an expensive assumption for us. We have found them to last only for several hundred cycles and they tend to fail even before that number of charges if they are kept on a trickle charger. It also takes several charge/discharge cycles before they work at full capacity. We have also had a lot of failures with new batteries that have been sitting on the shelf for a year or so. In a survival situation, NiMH batteries self discharge from fully charged to empty in two-to-three months, so in a survival situation you will be starting with batteries of unknown charge. I generally would recommend against them. I have a bunch of NiMH AA cells for my camera, but the only practical way to charge them is using a charger plugged into my car. If you want to go solar, it will take will take a five watt solar panel of power and about a half a day to charge four typical AA NiMH cells of 2000 maH hours plus. My plans are built around my supply of alkaline AA/AAA cells that I rotate through every couple of years. I’m confident that even if they sit for 5 years in my refrigerator, my batteries will still have a good amount of available power. Regards, – P. Smith

I’ve heard that there is now just one slot left for the next specialized Tactical Lifesaver Course. This class will be held on April 15-16, 2006, in Douglas, Georgia. A Iraq war vet Physician’s Assistant (PA) will teach you a lot of skills that the American Red Cross doesn’t. (Such as: how to prep an intravenous infusion, how to insert and orthopharyngeal airway, wound debridement, suturing, how to treat a sucking chest wound, and much more.) Don’t neglect taking this course. See:http://www.survivalreportblog.com/Tactical_Lifesaver_Course.html Because this is a true “hands-on” course, space is limited.

Letter from Rourke Re: Safe Room Doors on Budget

A vault door may not be necessary unless you really need a blast door or you are very worried about theft. If you are far enough from a likely ground zero and able to at least somewhat hide your door, a steel fire door will probably suffice nicely. For bargains, look for commercial demolitions, or contact people or companies who do this. Tell them you are looking for a swinging conventional doorway sized steel fire door, preferably with the steel frame, dent and scratch is fine. If you must buy new, find a 90 minute rated steel fire door. They have cheaper ones for residential use, commercial is always at a premium. Consistent with the recommendations for safe room doors, you want minimum of six points of attachment from door to frame. Best way to do this is three strong hinges with really heavy and deep screws on one side, and three deadbolts on the other side. You should space your deadbolts top, center, and bottom of the door handle side. To really be secure, add two more, top center and bottom center of the door. Go to a lock store or home hardware suppliers and get all deadbolts keyed the same. That can provide good security and protection at a more reasonable price. For combination entry, there are combination deadbolt locks also. For EMP concerns I would stay away from electronic ones. Those little key boxes that real estate agents use are nice, and can be hidden easily so you are never without a key. http://www.nokey.com/comlocbox.html – Rourke (http://groups.yahoo.com/group/survivalretreat)



Letter Re: A Bucket Clothing Storage Idea, and the Importance of Lanyards

Sir:

I think that you could use the five gallon bucket to put your clothing in and treat it like we store the wheat–with a dry ice or nitrogen purge.

Lanyards are a great idea for a lot of gear. For example, I use foam ear plugs with string between them for less chance of losing them. At the retreat I use them in conjunction use the ear muffs over the ears. The uses of the nylon cord are limitless when you are out in the boonies: “Where are my glasses? For gloves, run string between them just like our moms did, down the sleeves in our coats. A lot of our equipment already has holes in the handles. as appropriate, make use of them for lanyards. You can pre-set the available radius with pinch [plastic sliding cord] locks. My dad once dropped an aluminum pipe wrench down a well. I told him: “Now you know what the hole in handle is for!” On my $ 3,000 Gen 3 night vision goggles, I never neglect to tie and tape a cord! Thanks for you time and effort, – Gordon P.S.: The $20 that I promised you for the “Ten Cent Challenge” is headed your way.



Letter Re: Choosing Between a Shotgun and a Rifle for Retreat Defense

Hi,
I was wondering if the following items that I already have are a good start on a survival kit and what else would be good to add on. Ruger .22/45 pistol, two 10 round magazines, stainless steel blade fishing knife with regular blade, gutting blade, small scissors, probe, and flashlight, cell phone with flashlight, Savage Arms .22 bolt action rifle with scope, salt packets, duct tape, cold cereal in a good sealed case, and a standard military issue canteen. Also, I was looking at a 12 gauge pump action over a .30-06 bolt action. Which would be better? Thank you for your time, I know I have a lot of work to do, but better safe than sorry. – Declan

JWR Replies: It sounds like you have made a good start at getting squared away. Keep up the good work. Build up your food storage systematically.

The choice of a rifle versus a shotgun involves your expected range of engagements. If you live in densely wooded country or an urban environment, the versatility of a shotgun makes sense. Otherwise, a .308 or .30-06 is more appropriate. As your budget allows, you will probably want to own both a large caliber rifle and a riot shotgun. Most likely in the interim between those two purchases you will want to get a major caliber handgun–at least a .40 S&W, but preferably a .45 ACP. Since you have been training with a Ruger .22/45, a M1911 probably makes sense. (The Ruger has its safety, slide release, and magazine release in the same locations as found on the venerable M1911.)

Logically think through the rest of what you might need in the event of a full scale collapse. Water storage and purification should be at the top of your list. For fixed site retreats, a British Berkefeld water filter is appropriate. In a tactical “on the move” situation, the smaller Katadyn filters work wonderfully. Both are available from Ready Made Resources and a number of other vendors.

How the Asian Avian Flu May Affect Your Life: ABC News

o o o

I mentioned last weekend that I had dropped by the gun show table run by Darryl Holland (of Holland’s of Oregon), and sent him home a Browning A-Bolt bolt action rifle for muzzle threading with 1/2″ x 28 threadsand installation of a Holland’s muzzle brake. I was delighted to see that the barreled action arrived at our mail forwarding station today. Talk about a fast turnaround! He must have had it in his hands less than three days. The work was done flawlessly, as usual. I highly recommend Darryl’s work. IMHO, “tacticalizing” your bolt action rifles (by threading their muzzles) is a must.The same threads can be used for Smith Enterprise Vortex flash hiders. (If it is for a .30 caliber rifle you will of course have to drill out the rear section of the flash hider for bullet clearance.) The folks at Holland’s of Oregon really know their stuff, and they’ve proven once again that they can complete a muzzle threading order very quickly.

The Year Without A Summer (a.k.a. “Eighteen Hundred and Froze to Death” and “The Poverty Year”) By Tim P.

Since moving to Chenango County, New York in 2001, I have tried to do a bit of studying on the history of the area. My father lived in Fulton – North of Syracuse – as a boy and I spent the first 12 years of my life in Rhode Island with trips to the Upstate region for camping, family visits, etc. so I was not completely unfamiliar with the area. However, I had never really studied the history of the region and some of the things that I have found surprised me. I have always been fascinated by the catastrophes of the past – wars, epidemics, natural disasters, etc. and tend to study them. They can teach us about ourselves and of things to come. As they say, those who forget the past are doomed to repeat it. What I have found is one of those things.

Many people may not be aware of it, but there was a summer here – shortly after settlers first moved to this area – that was no summer at all. That summer had a killing frost every month of the year. The cause of this calamity was located practically on the other side of the earth from New York – Mount Tambora, on the Island of Sumbawa in what is modern Indonesia. This volcano erupted from April 5th through April 18th of 1815. During that time it ejected anywhere from 25 to 43 cubic miles of debris into the atmosphere. Only 25 of the island’s 12,000 inhabitants survived. As you will soon see the eruption of Tambora had worldwide effects.
For comparison, the Mount St. Helens eruption in 1980 ejected 0.67 cubic miles of debris – a piker! I was living 1,200 miles away from Mt. St. Helens – near Denver, Colorado – at the time and we had a fine layer of ash on everything and were informed that we should rinse things off before scrubbing them as the finish on a car – for example – could be ruined if one tried to scrub the ash off because it would act like sandpaper as it is essentially small particles of glass and stone. People with allergies and lung conditions were advised to avoid breathing the dust as it could aggravate their condition.

In any case, back to our story. The year 1816 started out to be a pretty easy one. The winter was slightly warmer than normal and fairly dry by most accounts I can find from New England and New York. When spring arrived, the temperature dropped somewhat, but nothing too severe and it remained dry. It was so dry, in fact, that local papers began to report on it. The Albany Advertiser stated they had ” …no recollection of so backward a season…the length and severity of drought checked progress of vegetation, grass withered.”
The dry, cold weather pattern continued until early May which delayed the start of planting in some places and the growth of crops that had been planted in others. However, the people suspected nothing because – as we all know – strange things can happen in springtime.

On May 12th a wave of cold air rolled down over the region – the northeast from coastal Connecticut down into Pennsylvania and Virginia was gripped by a frost. This weather lasted until around May 18. Then it moderated and with the increase in temperature came rain – soon farmers began their yearly ritual of planting. However, the warmth was only passing and on May 29th came a blast of cold arctic air – so cold that there was an inch of ice on many bodies of water. This too passed and those that hadn’t already started began their planting in early June.
On the 5th of June New England was basking in temperatures in the high 70’s and low 80’s. However, the weather was changing again. At the same time – from Quebec to Pittsburgh – another cold front began to move in. This one brought frosts with it as well. June 6th brought snow and cold to most areas. It snowed for hours in Elizabethtown, NY and many places had killing frosts. Wild birds roosted inside barns to try to stay warm and many died where they sat. Newly shorn sheep died in the fields from the cold. Crops were killed by the frost, most fruit trees lost their blossoms and many trees lost their newly formed leaves. It was beginning to look very bad for the farmers of the region. In fact, the Quebec Gazette warned: ” . . . nothing which may provide sustenance for man or beast ought to be neglected…”
After this cold front passed farmers rapidly began planting crops such as Barley, potatoes and beets that could make it to maturity by the usual fall freezes.

Remember that this was before hybridized and genetically engineered crops that mature more rapidly.
The rest of June brought warm temperatures. July started off well but on the 6th of July another cold front came that brought frost to many areas. Lake and river ice was observed as far south as Pennsylvania and huge temperature fluctuations accompanied the front. Some places experienced temperatures of 95 degrees during the day and dropped to below freezing within hours. Overall it was a disaster for local farmers.
August had more of the same. On the 13th, frost returned again to central New York and most of the crops that were growing were killed off. Even pastures and hay were doing poorly. August 28th brought more frost and the drought continued.

By September farmers had all but given up, although some planted winter crops to have them ready as soon as possible the next spring. Corn and other grain prices soared. Oats, for example, rose from a high of 12 cents a bushel during 1815 to 92 cents a bushel in 1816! In the spring of 1817, the worst of the shortage appeared. For example in DeRuyter, a farmer was forced to dig up some of his newly planted potatoes to get food on the table. The town sent an agent to Onondaga County to look for wheat and corn. When he returned and it was learned that he had been successful, it brought a “great rejoicing to the citizenry and tears to strong men’s eyes.”

The spring of 1817 brought some very high prices indeed. Corn was four to five dollars per bushel (prices not seen again until the 1970’s – over 150 years later!), and in some places wheat sold for any price that was asked. Many people barely survived and this brought about the great western migration toward Ohio and Indiana as farmers sought places with better weather conditions.

The strange weather brought about all around the world that year also brought us two classics of fiction. A woman named Mary Shelly and a man named John Polidori were both vacationing at a literary gathering that summer on Lake Geneva in Switzerland and were forced inside by the cold and dreary weather. The group huddled around the fire and told each other stories to pass the time. Both ended up publishing their stories. Mary Shelly’s was entitled “The Modern Prometheus” which is better known as “Frankenstein” and John Polidori’s was entitled “The Vampyre” better known to many as the modern Count Dracula. Both have been immortalized in film a number of times.

These days we do sometimes see some strange weather, but nothing like this. In my experience, people tend to believe that weather and famines of this type are things of the past and cannot happen any more, but we are not immune. In fact, modern farmers support many more people per acre of land than those farmers did in 1816 so we would, in fact, be in worse condition. How well will we fare when God sends the next year without a summer our way?
