Double gear coffee grinder thickness and time settings-Coffee grinder which brand is good

When grinding the beans, the thickness of the powder depends on how it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the coarser the ground powder. In terms of actual cooking, ESPRESSO machines take a very short time to make coffee, so the ground coffee powder is the finest, and the coffee powder is as fine as flour; it takes about one minute to cook coffee in the "plug wind" way, and the coffee powder is medium in size; American filtered coffee takes a long time to make, so the coffee powder is the coarsest, one by one like the Beijing grain on the shell beach. Grinding coffee powder of appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine, and cooked for a long time, resulting in excessive extraction, coffee may be very bitter and lose aroma; on the other hand, if the powder is very coarse and cooked too fast, resulting in insufficient extraction, then coffee will be tasteless, because there is no time to dissolve the water-soluble substances in the powder.

Coffee grinders come in a variety of brands and models, but ideally one that can adjust the size of the ground beans. When grinding with a bean grinder, do not grind too much at a time, enough powder for one use is good, because the longer the bean grinder is used, the easier it is to generate heat, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the cooked coffee.

Coffee beans contain oil Lu, so the grinder must be cleaned after grinding, otherwise the oil deposits, there will be stale smell for a long time, even if it is more advanced beans, but also ground into strange smell powder. After each use of the bean grinder, be sure to wipe the blade machine with wet market and clean the plastic top cover with warm water. But for flavored coffee popular in the United States, the added flavor is strong and heavy, and it will last a long time. It is best to put two spoonfuls of white sugar into it before washing. Of course, it is best to grind only the same kind of beans in a grinder, so there is no problem of mixing flavors.

Coffee beans grinding methods can be divided into coarse grinding, medium grinding and fine grinding according to their size. Use appropriate grinding methods depending on coffee equipment.

There is also a medium fine grind or a very fine grind finer than fine grind (into powdered coffee powder). The coffee beans are ground before brewing, only the required amount of ground and for the top grade. Coffee beans are ground into powder and their surface area increases to absorb moisture and oxidize easily. In short, with the passage of time, coffee powder also plays a role in the deterioration of flavor damage.

French press, corkscrew, drip, or mocha pots do not require a high degree of fineness in coffee powder. The knife pulp grinder (commonly known as the bean-cutting machine or the propeller grinder) cannot adjust the scale, and the thickness is adjusted according to the length of time. The particle size of the coffee powder is uneven, which is not suitable for making espresso coffee. The popular belief that an espresso machine is all it takes to make a good espresso is only half true. The other half is done by a more sophisticated two-gear grinder. The lower gear of this grinder is connected to a powerful motor to provide high-speed rotation force, while the upper gear is connected to the scale and twisted counterclockwise. The reading of the scale is getting smaller and smaller, and the upper gear is also decreasing. The distance between the lower gear and the ground coffee powder is getting finer. If the upper gear is twisted clockwise, the larger the scale value, the upper gear rises upward, widening the distance between the upper gear and the lower gear, so the coffee powder ground is coarser.

Double-gear grinder is to adjust the height of each other to set the coffee powder thickness, do not underestimate this grinder, its structure is extremely precise, without the double-gear grinder, it is impossible to brew thick, authentic espresso
