The 'refrigerator' without plugging in the power still keeps fresh food 9 times normal

Preserving fresh and modern food for up to 27 days without harming electricity, these are great benefits that a special 'refrigerator' is created by a Nigerian teacher who brings to life. poor people here.

Simple but unbelievably effective inventions, which don't cost too much, are the things that poor rural Africans always dream about. Even in modern life today, basic electrical equipment such as refrigerators also become extremely 'luxurious' for the people here due to the remote terrain conditions and the cost of using Electricity is too expensive.

Luck has come to poor Nigerians when a special cold storage tool works to preserve food in no way inferior to the refrigerator invented by Mohammed Bah Abba , a Nigerian teacher.

Special cold-keeping tool works to preserve food in no less than a refrigerator.

This 'unique' refrigerator does not need to be plugged in, does not cost much, can even be 'portable', but is especially effective in hot and dry weather conditions that make fruits and vegetables The fruit and the food were quickly damaged, rancidly preserving the food for nearly a month.

Mohammed Bah Abba, the inventor of the cooling system, especially changed the lives of poor Nigerians.

Mohammed Bah Abba was born into a family with a tradition of making pottery and clay. As a son of Nigeria, knowing the consequences of the scorching weather in Africa, as well as the wishes of the poor people, in the late 1990s, Mohammed created a technology-based application. Traditional pottery.

This "refrigerator" does not need to be plugged in, preserving food 9 times longer than normal conditions.

Based on the ancient idea of ​​a cold water pot, Mr. Mohammed built a special 'refrigerator' with a 'vase in the bottle' mechanism. Two large and small ceramic jars are inserted, in a large vase or space between the two pots will be filled with wet sand, and small ceramic pots will be used to store food and cover with a wet cloth.

The construction of the "refrigerator" consists of two large and small ceramic jars that are interlocked, the space between the two jars will be filled with wet sand, and small ceramic vases will be used to store food and cover with a wet cloth. .

In order for the two pots to function as a refrigerator, they should be placed in a cool, dry place. Then the water in the sand has been poured from the beginning to evaporate, the inner pot is cooled to only 4 degrees C, preventing bacteria from growing and keeping the food fresh.

The water in the wet sand will evaporate, the inner pot is cooled to only 4 degrees Celsius, preventing bacteria from growing and keeping the food fresh.

It can be said that this particular 'refrigerator' of Mr. Mohammed is a testament to the 'modern but not harmful' invention when startlingly cheap. It only costs 20 to 90 thousand dong (from $ 2 to $ 4) for each one, does not use electricity and can preserve food from fish, vegetables, fruits to 27 days, fold 9 times more than 3 days at normal temperature.

It can be said that this special 'refrigerator' of Mohammed helps people store food for up to 27 days.

This effective 'average pitcher' system has really changed the lives of poor Nigerians, the ability to store food for a long time and fresh longer for them to sell agricultural products is also higher. Since these pots are available, people here will not need to go to the market to buy food anymore, it is very convenient but also saves a lot of time.

Before his death in 2010, Mr. Abba continually improved his cold storage system, then he used his own money to hire local factories to produce 5,000 'refrigerators' distributed to 5 villages. Jigawa and 7,000 'refrigerators' for Nigerian locals.

The refrigerators created by this Nigerian teacher have significantly improved the lives of the people here, helping them to sell farm produce at a higher price, saving a lot of costs.

So far these have been widely used in rural areas in Nigeria, Cameroon, Chad, Eritrea, and Sudan. In 2000, Mohammed Bah Abba was awarded the Rolex Award for Enterprise award for honorable inventions. Time magazine once called for the invention of Mohammed's groundbreaking chiller as one of the great inventions of the year.
