Does the WDT Distribution Tool really improve extraction? This is probably the first question many coffee lovers have when they are new to coffee wdt tools. This time, we will discuss the types, functions, and effects of coffee distribution tools.
The first thing we need to understand is that coffee beans are ground in a grinder to form coffee powder. Different brands of coffee grinders have different performance, so the grinding effect of coffee powder is also different. This leads to some unevenly ground coffee powder, or worse, the formation of coffee powder lumps. And these chunks of coffee powder in the use of coffee leveler and coffee tamper
will remain lumpy during the process of tamping. It will not be able to form a uniform state with the coffee powder. Due to the presence of non-uniform coffee powder, during the espresso extraction, it will lead to the formation of the extraction of high pressure area is not consistent. The water will preferentially flow out of the low-pressure part, which is the surrounding area formed by the coffee powder lumps. This is the channel effect of espresso extraction. Small streams of water are ejected during extraction.
After realizing the problem, some people tried to break up the ground coffee, that is, all the ground coffee is in the same state, and after the coffee tamper is pressed and tightened, a stable high pressure area is formed between the coffee puck and the coffee machine group. This allows for a stable and uniform flow of coffee concentrate from the coffee portafilter
How can I break up the coffee pucks more efficiently? From the humble beginnings of wooden toothpicks to the current motorized rotary wdt tool. There are so many styles to choose from, but they basically fall into the following categories
1. Conventional manual coffee needle wdt tool, basically consists of 6-10 tiny needles, with diameters of 0.4mm, 0.3mm, 0.25mm, and a base to place the needles. The composition is relatively simple, need to be used manually, irregularly breaking up the coffee powder.
2, coffee rotary wdt tool, the biggest difference is that the powder needle formed a certain emission position, more regular to break the coffee powder block. And more efficient
3, electric rotary wdt tool, in the rotary wdt tool on the basis of increased electric function, only need a start, you can complete the work!
The above 3 different types of coffee wdt tools are equipped with 0.4mm, 0.3mm and 0.25mm needles. The finer the needle, the better the result.
Regarding how to choose the right coffee tool for you, you can choose according to your budget, with the same function, more on product quality and after-sale guarantee.
