Egg refrigerator / Tools for saving eggs

Egg refrigerator
Egg refrigerator

In the backward regions of Southeast Asia, some farmers rely on hens to lay eggs to make a living. However, in the high temperature and high humidity season, the bacteria on the eggs reproduce very quickly. Farmers cannot afford the refrigerator, and the eggs are easily spoiled and damaged, causing food waste and economic losses. The egg refrigerator uses physical knowledge to "evaporate and absorb heat" for cooling, and does not require electricity, and its shell is made of rice husk. This material is very common in rural areas and is also very environmentally friendly. Egg refrigerators can help poor farmers save eggs for a long time.
