A machine that grinds coffee beans manually

Coffee was planted in large numbers by Arabs in the 12th and 3rd centuries, and the world's first coffee shop was born in Damascus in the Middle East in the 16th century (1530). In just a few years, there were different numbers of coffee shops in more than 200 cities throughout the empire, from the ancient Constantinople to the Caucasus, from the Persian Gulf to Budapest, and the roads connecting these cities across the desert wilderness were dotted with mobile coffee tents to serve a steady stream of business travelers and troops. Coffee also spread to Europe in the same century, when coffee was taken to western countries with the Turks on a western expedition to Austria. Unexpectedly, it soon captured the hearts of Europeans. According to records, a packet of samples sent from Venice to the Netherlands in 1596 was the earliest coffee bean seen by Europeans north of the Alps. Legend has it that coffee was so rare in Western Europe that at first there was a joke that German housewives used chicken soup to make coffee. According to scholars' speculation, in the prosperous import and export trade of seasoning raw materials at the end of the 16th century, many coffee beans from the east began to enter Europe through Venice with developed economy and trade.

The most important index of coffee grinding is the speed and uniformity of coffee grinding. The so-called evenness is a relative index, at present, there is no so-called absolutely uniform grinder, so the so-called uniformity refers to the thickness of the vast majority of ground coffee. Of course, the uniformity of professional coffee mill is better. However, if you do not intend to spend so much money, but only want to use a hand mill or a small grinder to grind coffee, the grinding fineness adjusted is only a reference value, that is, most powders should be at such fineness. Therefore, friends who use manual bean grinders should observe the thickness of coffee powder after grinding coffee. Judging by the fineness of most coffee powder, it sounds a bit troublesome, but grinders such as hand mills have to do so.

It is a fact that a small electric bean grinder (such as a small grinder) grinds coffee with poor uniformity. Therefore, it is suggested that when grinding beans, it seems to shake up and down while grinding beans, such as drawing lots in a temple. The aim is to make the coffee beans as uniform as possible, but only as much as possible. But the biggest advantage of this machine is its fast grinding speed, which retains as much aroma as possible. However, the grinding speed of the hand mill is slow, and the aroma will volatilize a lot. If we have to compare the advantages and disadvantages of these two kinds of bean grinders, we can only say that each of the radish and cabbage has its own preference. There's not much difference.

The degree of grinding will be closely related to the extraction time and directly affect the taste. For example: the coffee grinded by hand mill or small grinder has a large proportion of coarse, so to get a mellow taste, it is necessary to increase the soaking time. On the contrary, if the fine proportion accounts for more, and want to pursue bright sour fruit and low bitter coffee, then it is necessary to shorten the soaking time.

For the same kind of coffee beans, when the water temperature and water quantity are the same, the thickness of finely ground coffee alcohol is higher, while the acidity is bright.

The first is to play, really need to shake the hand acid, and the cheaper the effect is worse, can not guarantee the uniformity of powder, there are hundreds of manual bean grinders will be better, but also can adjust the grinding degree, but generally speaking, it is still tired.

The second kind of electric blade bean grinder can not guarantee the flour quality at all. the coarse one is still granule, and the fine one is the same as flour.

The third is a qualified bean grinder, the grinding mechanism can ensure the particle size of the powder and the uniformity of the powder under the same grinding degree, but the price is very different. Basically, about 1000 is regarded as an entry level. Up there are commercial machines with higher precision, higher precision and greater powder output.
