Rice processing in Bangladesh

In Bangladesh, a nation that's never recorded a freezing temperature, rice growing is a year-round affair. But growing an aquatic crop in the dry season—October through March—is complicated, requiring high-yield plant strains and additional irrigation.

Drying the grains is more straightforward, though: As these workers spread rice thinly over a large field, heat from the sun warms it and the surrounding air, creating an arid environment to vaporize moisture within the grains. It's tough, toasty work—and important to boot, given that rice is the staple for the more than 160 million people who live in this South Asian nation.

在孟加拉国，一个从未记录过冰冻温度的国家，水稻种植是全年的事情。但在10月至3月的旱季种植水生作物非常复杂，需要高产植物品种和额外灌溉。

尽管如此，干燥谷物更为简单：当这些工人将大米薄薄地撒在一大片土地上时，来自太阳的热量使其和周围的空气变暖，从而创造了一个干燥的环境来蒸发谷物中的水分。鉴于大米是生活在这个南亚国家的1.6亿多人的主食，这是一项艰难、棘手的工作，而且非常重要。
