Bean grinder A high-quality bean grinder is the best investment to make your coffee brewed at home more delicious. This sentence is true and true.
If you look at it carefully, you can compare the pre-ground coffee powder of top-grade commercial bean grinders and the coffee powder of cheap home bean grinders. You will find that the coffee brewed from the former is really delicious. This was an interesting experience, but for me, pre-grinding would be less enjoyable from the taste of grinding before cooking. Moreover, pre-grinding coffee powder also ignores a very important point, which is that it is impossible to adjust the perfect grinding scale according to the grinding coarseness and boiling method of specific coffee beans. There are two types of
{burr, or mortar, and sharpener. Although the knife-grinding machine can also enjoy the fragrance of grinding coffee beans, unfortunately its capabilities are limited. There is a small blade with high-speed rotation in the tank of this type of bean grinder, which can cut and crush coffee beans into pieces. Finally, we ground up pieces of different sizes, ranging from fine powder to larger pieces. The only thing that can be adjusted slightly is the short grinding time, so the accuracy of particle size is very low. I strongly suggest here that you can upgrade it to a plate-type bean grinder. The interior of theDrain grinder is equipped with two cutting grinders. One is fixed, while the other is moved tightly against it, and drives in a motor or hand way. If you have a pepper grinding jar at home, you actually have a primary grinder, and I think freshly ground pepper adds a delicacy to the dishes, which is far away from one-tenth of the deliciousness of the coffee (because coffee powder is the main ingredient of coffee).
When choosing a bean grinder, you can evaluate whether it meets the needs and budget according to the four key points of the bean grinder. Let’s discuss these four key points below.
1. Grinding plateThe internal cutting plate of the grinding type bean grinder has two main shapes: a flat knife and a sharp knife. Generally speaking, grinding plates are made of metal, but relatively cheap bean grinding opportunities use ceramic grinding plates. The cutting edge design of the grinding plate has many geometric shapes and pattern patterns. The larger internal grinding is responsible for the initial breaking and cracking of the coffee beans. As the coffee crumbs slowly move out of the grinding plate, they will gradually be ground to a finer level until the size is so small that they can penetrate the gap between the two grinding plates. When adjusting the grinding scale, the gap between the grinding plates and the size of the coffee powder that can be opened to the grinding bean tank. The mechanism for adjusting the gap between the grinder can be divided into several types, but from the perspective of the user, it is either the scale of the rotary bean grinder or the axis of the bean grinder. These machines allow the bean grinder to make a very fine adjustment.
The current view of the coffee industry is that some grinding plates are most suitable for filter coffee, some are more suitable for exclusive slurry coffee, and some bean grinding machines try to build bridges between the two ends. If you are just on the stage of your coffee journey, please remember that the difference between the two is really small. If the bean grinder you bought is more oriented and suitable for grinding a specialized crushed coffee powder, it will not make your filter coffee unable to be eaten.
If the budget is sufficient, it is recommended to buy a metal plate grinder, as this type of grinder is usually of better quality (of course, there are exceptions to any rule, but I think this is a good purchase indicator). When the price of the bean grinder goes up, everyone's money is often spent on the grinder. The quality of this type of bean grinder is better, the grinding results are more accurate and the machine's life is longer.
Be particularly careful about cheap machines that look like a disc-type bean grinder. This type of bean grinder usually costs less than 50 ying pots, and its grinding plates cannot be ground properly, but instead crushes or crushes coffee beans. Currently, there are reliable electronic bean grinders on the market that cost about 100 British Pots. We personally recommend this type of bean grinder. However, the coffee powder grinding from this type of electronic bean grinder is not fine and cannot be made of exclusively condensed coffee. The bean grinder that can grind out coffee powder is much more expensive, the main reason is that a specific set of parts: Mada.
2. Adjustment mechanism for grinding sizeAs discussed in the previous pages, there will be a mechanism inside the grinding bean grinder that can be pulled or placed closer to the distance between the grinding plates, so that it can be adjusted according to different boiling methods. There are two ways to adjust the distance: scale or unscaled. The distance between the scale grinder moving grinder is fixed. This method is often quite helpful because the scale is equivalent to indicating how much the grinding distance should move, and it is also easier to revert the change or setting of the grinding distance. However, please note that the length of each grid is not a standard, and the size difference between coffee powder particles in a single grid of some bean grinders is much greater than that of other models.
Often people often think that unscaled bean grinders are better and are almost necessary for the production of formal thickened coffee. The adjustment amount of grain size of the optimum slurry coffee powder must be very small, and the single size of many scale bean grinders may jump from too thick to too thin. The unscaled bean grinder is indeed a bit tricky and may feel frustrating. However, most unscaled bean grinders will have some visual marks or "scale" marks that some manufacturers think are reasonable.
bean mills are paid to Mada. Grinding coffee beans requires sufficient torque and force, and the motor performance of low-priced bean grinders is often very limited.. The more refined the grinding particles, the higher the torque the motor is, so cheap bean grinders often fail to effectively grind the exclusively condensed coffee powder without getting stuck. Bean grinder manufacturers will use this method to prevent users from adjusting the grinding scale too fine.
The bean grinder that can grind Yi-style heavy coffee powder is because it has a powerful horse, so the price will increase rapidly from 200 GBP. This type of bean grinder has a high revolutions per minute (RPM) so that enough movement can be created and the degree of fineness that must be grinded into the powdered coffee.
There are currently no evidence of whether the grinding speed will affect the taste of coffee, but top-grade bean grinders can often grind at lower or variable speeds.
4. In the traditional way, there will be a bean tank for storing coffee beans at the top of the household bean grinder, which can put the amount of coffee beans in a pack of coffee beans. This design has begun to disappear now for two reasons: first of all, the consideration of freshness. The best storage environment for coffee beans is a dark, dry, sealed container. The bean tank on the bean grinder actually does not meet these conditions. Furthermore, people's habits of drinking coffee are different. More and more people will put two or three kinds of coffee beans in the cabinet. To put it simply, it is too impractical to empty the bean tank and change different coffee beans every time. Downs, only a single portion of coffee beans will be placed into the bean grinder at a time, and then cooked immediately after grinding. Therefore, beanless bean grinders or single coffee bean grinders have begun to appear on the market. Then, some focus points start to place the powder in the bean grinder. Each bean grinder will leave some coffee powder, although the goal of a single bean grinder is as close to zero powder as possible. Traditionally, the design focus of the bean grinder with bean tanks is not very much on the powder because the main goal is convenience and stability to a certain degree. Think about how you want to brew coffee⸺If you want the elasticity of a single grinding, or you must always adjust the grinding scale significantly - so that you can have more information to choose the most suitable bean grinder.If you are considering buying a bean grinder, the above are the main considerations, so you should know whether you want to make exclusively condensed coffee, or even try it in the future. In addition, there are some aspects to consider: beauty, noise (volume, ears or degree of intimacy), and whether there is after-sales repair service for the product in your residence.
For many people, importing products with beautiful prices from abroad is actually very attractive, but I have always supported after-sales service with better parts replacement and repair. This is true for bean grinders, and even more so for Italian-style sintered coffee machines.
If you don’t discuss the hand bean grinder here, it will be a failure. With the lack of expensive parts of Mada, you can buy a high-quality hand-mill machine with a price that is much lower than the same-grade electric grinder. However, there are several important points to note:
Enterprise bean grinders are often ceramic grinders, but now there are quite a few manual bean grinders that use metal grinders. If you want high-quality grinding results at a discounted price, choose a metal grinding plate. If you just want to experience grinding coffee and see how big the difference is, you should buy a 25-inch pill to buy a one-in-door grinder.
In addition to the grinding plate itself, cheap bean grinders are often a mechanism that maintains the moving stability of the grinding plate. The transmission axle usually shakes during the rotation of the bean grinder, which means that the distance between the grinder will change, so the size of the coffee powder will be inconsistent. The better-quality hand bean grinder will be better in terms of material and design to prevent this kind of unstable occurrence.
There are several hundred or thousands of yuan (British pounds) hand bean grinders, the difference is its material, precision of the design of the grinder and bean grinder, and the quality of the work. The performance of a platform's manual bean grinder priced at 250 British Porn is often equivalent to an electric bean grinder priced between 500 and 1,000 British Porn. The price you pay is the effort every morning. Hand grinding coffee beans costs a lot of effort, especially when grinding scales are fine.
Some people love this genre and enjoy the feeling of working a certain mechanism, then producing fresh and grinding coffee powder, making the whole process better for cooking and drinking. On the other hand, there are people like me who feel that the process is more dysfunctional - I think the money spent on the electric bean grinder is totally worth it.
