Modern fridge was available
1923
Invented by Swedish engineers, it was the advent of the refrigerator that allowed people to eat cold drinks and ice cream in the summer.
Some people think
, ancient technology is not developed, in the hot sun, it is difficult to taste cool cold drinks, is this true? In fact, it is not, there are still many cold drinks in ancient mainland China.
In the Western Zhou Dynasty, people already used ice cubes, there were special officials to manage these ice cubes, and by the Spring and Autumn Period, chilled drinks had already appeared in the market, and the ancients mixed juice and ice cubes together to make cold drinks, which is today's iced juice.
In the Tang Dynasty
，
Ice cubes are used even more
The market is full of cold drink products
Attracted a lot of people to buy
Merchants also add sugar to the thawed frozen water
Thus promoting consumption
。
Archaeologists unearthed a mural in the tomb of Prince Zhanghuai, which depicts the scene of the maid holding a tray, and in the tray is a Tang Dynasty ice cream. at
Tang poetry
Such a grand scene is depicted in the "Suhe Mountain Fu".
By the time of the Song Dynasty
The types of cold drinks are even more varied, and there are also departments that develop cold drink products, that is
"Ice well business", the emperor will also reward those meritorious ministers, cold drinks. Of course, cold drinks are not the patents of the nobility, and the phenomenon of folk hawking is also very prosperous. In the commercial street of Kaifeng, cold drink stores have emerged, and various types of cold drinks have attracted a large number of people.
so
, ancient processing of cold drinks of ice cubes, where did they come from?
In fact
The reason is very simple, although there is no ice, but you can save the ice, the Zhou Dynasty, the ice cellar has appeared, the ancients in the winter to chisel the ice, and then put it in the ice cellar preservation, summer can be taken out and processed into cold drinks.
These ice cellars are fifteen meters deep
Enough ice cubes can be stored
。 The reason why they can be preserved until the summer is also because the ancients mastered the technology of heat insulation and insulation, laying some straw at the bottom, placing ice cubes, and then covering them with leaves, etc., and finally sealing the ice cellar for storage, so that they can be retained until summer. I have to say that the wisdom of the ancients is still very superb, what do you think?
