Work begins: first remove the brewing handle from the coffee maker. (need to pay attention to two things: first, always buckle the hand on the brewing head to keep warm, do not put it on the warm cup or plate or other places, otherwise the low temperature handle when brewing coffee will lower the temperature of the brewing water and cause the coffee to go sour. Second, the coffee grounds inside should not be deducted before brewing the next cup of coffee, because the copper head under high temperature will produce a peculiar smell, and the coffee grounds can absorb the smell. Buckle the hand to the brewing head, press the brewing key to wash the handle and the brewing head, and shake the handle constantly in order to rinse the coffee residue glued to the brewing head. (note: if you load the powder directly without rinsing the head, the residue glued to the head will be extracted again, causing the coffee to become bitter and astringent. In addition, this is also equivalent to releasing water in the front section to prevent the boiling water from being too hot, resulting in excessive extraction.

You can load the powder now. (it should be noted that there is no powder left in the dispenser. Each time it is boiled and ground, the coffee powder will oxidize completely after being exposed to the air for a few minutes, and the brewed coffee will not be able to drink. Now some coffee shops are used to filling up their dispensers, which is not correct. The right thing to do is to quickly pull the dispenser lever while grinding the powder, turn it off when the handle is almost full, and continue to pull the dispenser lever until all the coffee powder in the dispenser falls into the brewing handle. Smooth the powder in the handle with your hand or scraper. (two precautions: first, wipe the powder back and forth when applying powder to make sure that the coffee powder fills all the gaps in the handle. If you use your hands, remember to wash your hands first. Second, the excess powder should be smeared into the dregs bucket, do not wipe back the dispenser, otherwise the coffee powder burned by the high temperature handle will affect the taste of the next cup of coffee and hit the handle laterally, the function is to make the coffee powder on the edge of the filter fall into the filter. (note: do not overpower, generally also in the 5kg, otherwise it is easy to concentrate coffee powder on the other side of the filter. In addition, you can only knock once. Xu has seen many people knock many times, which is incorrect, because repeated tapping on the outside of the handle will concentrate the coffee powder to the middle of the filter, creating an edge gap and making the coffee extraction unbalanced.
