Good coffee starts with a good grind. There are two different types of (เครื่อง บด เมล็ด กาแฟ) Coffee grinder . The blade and burr grinder (เครื่องบด). Generally, the blade grinder is much more commonly used because they are quite affordable. The only downside of blade grinder is that they don’t grind evenly, as a result, they roasted coffee beans is ground in all sizes with some big and other small. Experts in the preparations of coffee admit that a bad grinder is the cause of poorly prepared coffee tea. A poor grinder might not grind your coffee beans evenly causing it to be unevenly extracted.
It is quite difficult to get a cheap coffee grinder (เครื่องบดกาแฟราคาถูก) because they are mostly expensive. Regardless of the price, what you need is a solid burr grinder that can grind your coffee beans right into uniform/consistent sized pieces. According to the way you want to make your coffee drink, you can engineer the burr grinder to process the coffee before brewing according to the size you that will best serve the purpose.
Blade grinders grind the coffee beans into small pieces of different sizes, in other words, it produces an inconsistent grind of coffee beans. Now the problem comes when it is time for brewing, due to the inconsistent sizes of the coffee beans pieces, the big and fine pieces don’t extract the same way while brewing. Bigger pieces take more time to brew while the smaller ones lose their flavor to the hot water during the brewing process. Therefore, mixing the small and bigger particles will cause you to have different rates of extraction. In other to get similarly sized particles, you will need to get a burr grinder (เครื่องบด). These grinders have a sharp cutting surface, which can be adjusted to get precise sizes of the coffee beans particle resulting in having a more consistent grind.
