Survival guide - Refrigerate food without electrical powerOne of our most critical uses of electricity is for water and food refrigeration. Of all the stockpiling systems accessible to us, sustenance refrigeration is likely the most generally utilized. It permits us to keep fresh foods fresh, without ruining, and keeping extra cooked food so they can be utilized rather than squandered. The issue is that current refrigeration obliges power.

In a grid-down situation one of the things we will miss the most is the lack of refrigeration. This will make it critical to preserve any foods as soon as they are harvested, as well as only preparing the amount we are about to consume. Otherwise, food will go to waste.

In any case, what did individuals do before the creation of advanced refrigeration? Is it accurate to say that they were not able to keep foods for more than a day or two, or did they have different method for keeping food from ruining? From what I’ve found in my investigations of history, I’d say it was a mix of the two.

Cooked foods will really keep for a period, before they go awful. Going in Mexico, there have been commonly when I’ve eaten food that had been forgotten on the table from the earlier day. While this would alarm the normal American homemaker, in all actuality if the food is warmed up enough, it will slaughter off any microscopic organisms that have gotten into the sustenance overnight.

In past times, before refrigeration, they had various methods for keeping foods from ruining, including a large portion of the strategies for conservation which we utilize today. They likewise saw how keeping food cool would help to keep it from ruining and took whatever methods they could to keep foods cool.

Natural Cooling

Contingent upon where you live, the atmosphere and the season of year, there are various methods for keeping foods cool or even frosty, without utilizing the cooler. While not these thoughts will work for all individuals, they are every single compelling method for keeping food cool.

Utilize the outside

When we lived in Colorado and New York State, we had regular refrigeration for a while of the year. Temperatures amid the winter would frequently be colder than our cooler. Along these lines, we would leave things outside, either in the (unheated) carport or in the snow. This utilization of the characteristic icy was basic in the beginning of our nation, when they didn’t have refrigeration. Food canisters, open to the outside, would be fabricated outside the home or even in the kitchen. Indeed, even meats could be put away along these lines, with no peril of eating them.

A Well or Cavern

Anything that is subterranean will be cooler than being at ground level. Old fashioned way, where men really burrowed them with scoops, would dependably be cooler than the encompassing temperature at ground level. It was normal to hang a pitcher of milk or a backside of meat in the well, to keep it cool.

On the off chance that somebody had a hole on their property, they were fortunate. That buckle would dependably be cooler than the surrounding air. I recall going into cenotes in Mexico, which are underground lakes. Despite the fact that we were in the Yucatan Peninsula and it was more than 100 degrees at first glance, it would be decent and cool underground.

Keeping it in Water

On the off chance that you have a running stream accessible, it makes an extraordinary method for cooling food. Simply pack the food in a water-tight compartment and submerge it in the water. In a perfect way, you need it to be two or three feet beneath the surface, underneath where the warmth of the sun can reach. The same should be possible with a lake or pond, in spite of the fact that it may not be as successful.

The Basement

The basement essentially exploits the thought that the underground temperature will be cooler than the over-the-ground temperature will. In time long past times, they would burrow a basement under the house or behind it, with a specific end goal to store their produce, particularly on family cultivates. The cooler temperature of the basement would help the produce last more.

You can make a basement by delving a gap in the ground and putting a plastic stockpiling canister in it. Spread the receptacle with something to go about as an encasing, for example, cut long grass and afterward put something over it to shield it from creatures attempting to uncover it. This can be a bit of plywood or an old entryway that is lounging around.

Obviously a bigger basement will permit the capacity of more deliver. That obliges delving a little collapse the ground, balancing out it so that it can’t collapse and after that putting an entryway on it. A few individuals construct them over the ground, beginning by building a sandbag structure and afterward covering it over with earth to make a little slope. The expansion of an entryway completes it off.

Evaporative Food Refrigeration

Another method for cooling food is by utilizing vanishing. At the point when water dissipates, it needs to retain a ton of warmth to transform from a fluid state to a vaporous state. That is the means by which sweating serves to cool your body. This can likewise be utilized to keep food cool, by building an evaporative fridge.

The Zeer Pot

Zeer pots have been being used in Africa and Asia for quite a long time. This is one of the most straightforward iceboxes you can make, and it lives up to expectations by vanishing. The pot comprises of two unglazed clay pots, which will settle within one another, with some space between them. That space is loaded with sand.

To make a Zeer pot, you initially need to locate the two pots to utilize. Verify they are unglazed, as coated pots won’t work. Put enough sand in the base of the bigger pot so that the highest point of both pots will be level when they are settled. At that point, fill the space between the two pots with more sand, preventing around an inch from the lip of the pots.

To utilize the Zeer pot, water is filled the sand, immersing it. That water will leak out through the external pot, where it will begin to dissipate, cooling the entire pot.Food set inside the inward pot will be kept decent and cool. Putting a wet fabric over the top serves to keep the cool air in. Vegetables kept in a Zeer pot will last three to four times longer than those forgot.

Evaporative Shelf Refrigerator

The same thought as the Zeer pot can be utilized on a bigger scale, by taking a metal or plastic racking unit and wrapping it in fabric and wetting the fabric. As the fabric dries, the water retains the warmth inside the racking unit, cooling it and keeping any food inside cool.

The one issue with this sort of cooler is that you need to wet it down a few times each day or it will lose its viability. A little pump and a store of water could be utilized, yet just on the off chance that you have a wellspring of electric energy to run it.
