The Underground Food Storage





Rationale: The Underground Food Storage

Armed conflict, the World’s Deadliest War frequently has a disruptive effect on agricultural production and food availability. The Underground Food Storage is design to use in this situations, where human fight for food.

A few degrees can make a big difference when it comes to food storage. Foods can deteriorate and spoil, with major causes being incursion of moisture, oxygen, high temperatures, light, and animal infestation. But for many of the world's poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity. Therefore storing food undergroun not only can keep food longer and secure (where when there is a shortage, people store food from others), also in some cases it can save spaces in refugees.

The Underground Food Storage comes with a shovel slided onto the lid, either for the first time digging the hole, or uses it as a ‘brush’ each times before openning it (aviod dirt falling in). Inside are airtight ‘food grade’ containers, common and inexpensive plastic polyethylene containers with sealable see through lids that mice won’t chew into.

Manufactue:

Use injection molded Polypropylene (PP), this type of construction offers maximum durability and strength. At the same time it’s cost effective.

The rubber gasket lid with additional wall thickness at the plastic hinge areas and corners, which enhances durability. The lid features tremendous stress crack resistance and impact strength, it has enough rigidity to withstand a reasonable amount of weight, providing strength, durability, and safety.

* Crowned rib design adds strength and durability.

* Lightweight lids supply good structural integrity

* Lids maintain impact resistance at extremely low temperatures.

Provided by The Food Aid organizations, instead of dividing big bags of dry food to refugees, they just give each family the Underground Food Storage, with dry food packed inside already by machines, which saves time and labour cost. As now in some armed conflict areas government send money to buy food locally, rather than unwanted produced food, this handful of essential pieces of food storage equipment can help it all stay organized.

Here's a list of some common grains, and key food items:

Wheat

Corn

Rice

Rolled Oats

Hulled Barley

Rye Buckwheat

Millet

Beans (mung, pinto, navy, refried, and so on)

Pasta (a variety of types)

Sugar, sault

Dry chilies

Fortified flour

Reflection

For this project, I had a deep look at armed conflict situations in Africa, especially in the areas of providing long term food aid to civilians in Africa. The World’s Deadliest War, Armed conflict frequently has a disruptive effect on agricultural production and food availability, therefore designing a long term food aid system may be helpful.

As available now, in Africa the food aid provide big bags of rice and other dry food like corns and beans, but it will take lots of time dividing them to each family, so the Underground food storage can solve this problem perfectly, all dividing process is done by machines, and this can be achieved as I asked people who work in factory. The underground food storage can avoid food been stolen by others, as well as keeping food longer.

I looked into areas like food container design method, and situations in Africa, where they don’t even have ‘food grade’ containers to contain food, also watched many YouTube videos about those as well, also found the cheapest material and method too.

As I put myself into the users shoes, I found that they will need tool to dig the whole, so I designed an slotted in shovel on the lid, where they will be slotted onto the rib design of the lid, then as I tried to carry more than one large containers, I found it will be slippering, so I made the bottom of the storage box just to fit onto the rib of the lower one when put them one on one.

After this project I found myself thinking things more carefully, and know many things about ‘food grade’ containers, and large rotationally molded containers, because I went to shop to look at plastic containers, how the lid is designed for holding food, and talk to others too, also went to look at the hinge of large rubbish bins, but used plastic hinge as avoiding dirt.

I also learnt something extra about keeping fresh food longer, as first I went too far, thinking of designer a non electric refrigerator for the world’s poor, vacuum forming is the best way, then there’s the old way ‘pot-in-pot’ method. Which I found interested and want to share about.

I challenged myself within the time line of this project, starting from knowing nothing about armed conflict and container design, but now I know so much, and really enjoyed doing this project.
