一种很酷的食物保鲜法

 

     A few deGREes can make a big difference when it comes to food storage. Foods can go bad if they get too warm. 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. 

 

    在储存食物的时候,仅仅几度的温差就可能产生很大的影响。 如果储存温度太热,食物就会变质。 但对世界上很多穷人来说,要找到一个冷藏食物的好办法很难。 对他们而言,冰箱不仅价格昂贵,而且还需要用电。 

 

    Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly. 

 

    然而变质食物不仅会威胁到人们的健康,还会导致经济损失。 农民不得不扔掉没有及时售出的变质产品,这样一来他们就会亏钱。 

 

    But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the "Pot-in-Pot Preservation/Cooling System." It uses two round containers made of clay. A smaller pot is placed inside a larger one. 

 

    但是,1995年,尼日利亚北部一位叫做默罕默德·巴·阿巴的教师找到了一个解决办法。 他发明了“罐中罐储藏和冷却系统”。 该系统使用两个由黏土制成的圆形容器, 把小罐子放到大罐子里面。 

 

    The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system. 

 

    用潮湿的沙子填满两个罐之间的空隙。 内罐里可以装水果、蔬菜或饮料。 然后用一块湿布覆盖住整个冷却系统。 

 

    Food stored in the smaller pot is kept from spoiling through a simple evaporation process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving. 

 

    经过一个简单的蒸发过程,可以使得小罐中储存的食物不容易变质。 两罐之间的沙子中的水分经由大罐的表面蒸发,使大罐外部的干燥空气开始流动。 

 

    The evaporation process creates a drop in temperature of several deGREes. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks. 

 

    这个蒸发过程可以让温度降低几度。 从而使得内罐温度较低,让内罐中的食物避免有害细菌的威胁。 有些食物用这种方法储存可以保鲜几个星期。 

 

    People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby. 

 

    整个尼日利亚的人民都开始使用这一发明, 而且它在非洲其它国家的农村地区也越来越受欢迎。 默罕默德·巴·阿巴以个人名义出资为自己的社区和附近5个村庄提供了5000个第一批的“罐中罐系统”。 

 

    In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. 

 

    2000年,瑞士劳力士钟表公司授予他“劳力士事业奖”。 该奖项是专门表彰那些为了提高人类知识水平、改善人类生活而努力研发新项目的人。 

 

    A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects. 

 

    委员会认可的项目包括自然科学、医学、应用技术、探索、环境和文化历史。 获奖者将得到经费援助,以助于他们继续开发和扩展他们的项目。 

 

    The awards are given every two years. The next awards will be presented in late two thousand twelve. Last year, Rolex launched the Young Laureates Program for the younger generation. 

 

    该奖项每两年颁发一次。 下一届的颁奖将于2012年底举行。 去年,劳力士专门为年轻一代研究者们设立了一个“青年杰出者奖项”。
