Many people know that drinking coffee is good for freshly ground, and to make freshly ground coffee, you must use a bean grinder, especially in the process of making home coffee. After all, there is no need to spend a lot of money on drinking coffee in a family to buy a coffee machine that can automatically grind coffee beans.
From the moment I decided to make my own coffee, I should have a bean grinder and brewing utensils. Should I choose a hand-crank bean grinder or an electric bean grinder? Today, Xiaole will talk to you about this.
People make coffee at home, except for the fever level, generally don’t spend too much budget, but how to buy the right tools at a reasonable price is indeed a headache. Friends who have a certain foundation in coffee know the importance of bean grinders because they involve secondary processing, and the uniformity of the powder's thickness directly affects the flavor of the coffee.
But it is not advisable that the more expensive the better. After all, there is always a process. If you pay for a qualified tool, at least you have entered the ranks of freshly ground coffee, right?
Advantages of hand-cranked bean grinder VS disadvantages
Advantages of hand-cranked bean grinder
1. Cheap price: The price of a home-based manual bean grinder is usually only a few dozen yuan, and the style and material are better, which is only more than one hundred yuan. Among the bean grinders, the price is the cheapest bean grinder.
2. Can be used as decoration in the house: Manual bean grinders are mostly made of solid wood or cast iron, with beautiful style and color. In addition to grinding coffee beans, they can also be used as decoration when not in use.
3. Have an atmosphere: Three or five friends gather together, take out their hands to make coffee, to increase the fun of making coffee and make the coffee more atmosphere.
4. The grinding thickness can be adjusted: This is a pretty good advantage. It can adjust and fix the grinding degree, so that the grinding thickness can be ensured to be consistent for each coffee grinding. This is more convenient to control grinding than an electric bean grinder.
5. Widely applicable: No power is required, it can be used at any time, whether at home, office or outdoors, it can be used at any time, with wide applicability.
Disadvantages of hand-crank bean grinder
1. Inefficiency and labor-intensive: This is indeed a pity for manual bean grinders. Electric bean grinders can rotate thousands of times in a minute, while hand grinding only takes hundreds of times in a minute. Therefore, the efficiency of grinding beans is quite low. If you grind dozens of grams of coffee beans, it will really make your arms sore.
The impression that the bean grinder is very tiring to grind. At present, the domestic market is more popular for medium and deep roasting of coffee beans, and the beans are still easy to grind. You can try sitting on a stool, clamping the grinder to your knees, and then turning it on. To be more labor-saving, you don’t have to press down hard.
2. Relatively poor durability and troublesome adjustment of scale: The bean grooves on general manual bean grinders are screwed on the wood at the bottom of the seat with screws. After using more times, the gap between the screws and the wood will increase, resulting in the screws not being well fixed on the wood at the bottom of the seat, which is a little worse than the electric bean grinders.
Handshake bean grinder has no scale prompt, so to change a thickness, such as changing from normal pressure to the thickness of the siphon pot, you need to explore and adjust it, wasting some time and beans.
Regarding the relatively uneven hand grinding, it is mainly due to the design problems of the grinding disc. Most hand grinding uses conical sharpening knives. The characteristic of this knife is that it is fast but uneven. The relatively uniform sharpening knives are parallel sharpening knives, but there is another characteristic of parallel sharpening knives, which means that it takes 3-5 times more time to grind the same number of powder, so hand grinding basically does not use parallel sharpening knives.
▲ Parallel sharpening knives, you can think of the stone mill for grinding flour in rural areas. By adjusting the spacing between the upper and lower grinding discs, the powder is controlled with high precision and even grinding.
Most of the hand-cranked grinding is a conical grinding knife, and it is ground through the channel of the mother and child grinding disc. Because the spacing between the upper and lower parts of the sharpening knife is large, the grinding is fast but the accuracy is low.
Beginner's hand grinding is very cheap. Xiaole recommends that if you are not sure about it, you will like coffee. If you just try it in the beginning, don't invest too much first. If you like it, you can upgrade.
So, don’t buy an introductory hand-cranked bean grinder that is too expensive. I personally think it’s enough for about 100 yuan. Friends who have a lot of money can ignore the price part, but the most high-end ones are mainly cone knives, and the uniformity is not significantly improved.
choice of grinding core
hand-cranked bean grinder movements are divided into two types: metal and ceramic. The metal will heat up when grinding, which will evaporate the aroma of the coffee beans in advance; the ceramics are fragile, but the ceramics will basically not heat up, so the obtained aroma is corrected.
Brand introduction
Many people are using Zhenghuangxing’s A12 for economical and affordable. Kyocera, HARIO and TIAMO are also good, HARIO counterfeit Kyocera, TIAMO counterfeit HARIO.
HARIO's grinding core is manufactured by Kyocera and assembled by China. The grinding core of Kyocera CM45 can grind the powder needed by Espresso. I personally feel that the powder for espresso is better or special electric grinding (the best hand grinding is not counted, such as HG-ONE).
[TIAMO] is a Taiwanese brand that is almost all produced in mainland China, and TIAMO's plastic is just the same.
【Japanese Kyocera CM-45CF】: It is very difficult to grind and is very convenient to clean.
【Zhengshaking AKIRA A-13】: The cast iron grinding core is evenly fine and the grinding coarseness is not evenly uniform.
[Japan PROLEX]: Recently, it is more popular, fine grinding powder is better, and ceramic core grinding.
[Zassenhaus Panama stainless steel hand-crank bean grinder]: It is fixed with double shafts, steel conical grinding head, is a classic European hand-crank bean grinder brand. The center shaft is fixed and the grinding powder is evenly produced. It is very excellent. It can even grind the fineness of esp
