Coffee grinder cleaning and maintenance course Operation hand Mill and Electric Mill how to clean coffee powder

Nowadays, many friends like to grind beans and make coffee at home. Of course, there are also many friends in Qianjie to inquire about the question of buying bean grinders. According to the unified reply here, Qianjie is not a professional mechanical evaluation, and most of the front streets of bean grinders on the market have not been experienced, so which bean grinder is not recommended point to point.

People with discerning eyes can also choose a bean grinder of their own approval according to Qianjie's rough views on the performance requirements of the bean grinder, avoiding the minefields known and shared in the front street. Although the brand and model of the bean grinder cannot be accurately recommended to everyone, Qianjie believes that buying a suitable bean mill is an important step, and future maintenance and maintenance are more important. The maintenance of the hand mill is relatively simple, but it can not be ignored. Generally speaking, the precision of the all-metal hand mill is already very high (refers to the bearing and connection), and many hand mills can be completely disassembled. After grinding coffee by hand, there are usually fine coffee shavings attached to the bottom of the grinding, as will be observed after grinding, and it is necessary to clean up these fine dust after grinding. Of course, there are two places worth paying attention to, one is the powder warehouse, the other is the grinding bean warehouse. Even if you "shake" the powder beans in the powder bin by slapping, there will still be some fine powder that is not easy for the naked eye to notice, which can be verified by wiping your fingers on the inner wall of the powder warehouse. This can be cleaned with a brush, if the long-term accumulation is not cleaned, the powder cartridge is prone to fuel consumption.

And the bean grinder is the most easy to ignore, in fact, when grinding beans, there are also some fine powder and debris left in the knife head, ordinary fine powder can be solved by blowing balloons into the bean warehouse, while some fragments are stuck on the knife head (there is a sense of jam when turning the bean grinder), you need to adjust the grinding plate to the rough direction, and after the debris passes smoothly, you will return to the original scale and turn dozens of times to make sure there is no foreign body.

Then there is disassembly and maintenance, disassembly and cleaning does not need to be done every time after grinding the beans, if it is often used, it can be disassembled and cleaned about once every half a month. If the bean grinder needs to be sealed and not used for a period of time, it also needs to be disassembled and cleaned before storage. The main purpose of disassembly and cleaning is to clean the coffee powder on the bearing and the cutter head, which is difficult to clean if it is not removed. At the same time, we should also pay attention to the wear degree of the cutter head, which is easy to consume. If it is often used, the cutter head will have a certain loss after 2 years. The most obvious impact is the fineness of grinding (the increase of fine powder). Therefore, it should be replaced regularly.

As for such questions as "can it be washed with clean water after disassembly", it is recommended to consult the bean grinder manufacturer. At present, all the stainless steel hand mills tested in Qianjie can be washed, but it must be noted that the components are dry before assembly. If the bearing is made of stainless steel, it also needs to replenish the lubricating oil regularly, which means that the bearing needs to be oiled when you have resistance in the idling bean mill. The maintenance of electric mill is similar to that of hand grinding, and it is also the cleaning of fine powder and residual powder, the maintenance of cutter head and the inspection of circuit. Basically, no matter how high-quality the electric mill is, there is a common problem of "eating flour" (just eating more and eating less). However, if you do not clean the bean grinder every day, the problem of "eating flour" and "spitting powder" will become more and more serious.

"eating powder": refers to a unit of coffee beans ground to produce less than 1 unit of coffee powder, the less part is stuck in the bean grinder. "spitting powder": refers to a unit of coffee beans ground to produce more than 1 unit of coffee powder, the more part may be hidden in the bean grinder. To solve this problem, a small amount of coffee beans will be used to "wash and grind" before formal grinding to ensure that there is no flavor. After grinding, the residual powder of the powder mouth is also blown out by blowing balloons. If you are not familiar with the machinery, Qianjie is not recommended to dismantle and grind it by yourself (according to Qianjie's experience, you can always have a few more small parts after installation), clean up the fine dust in the grinding plate, you can use a special cleaning powder to grind and clean.

If one day you feel that the brewing state of the ground coffee powder is not the same as usual, it is time for your bean grinder to be cleaned deeply. Another point of attention of the electric bean grinder is the circuit problem. Checking the circuit condition of the bean grinder regularly can avoid many accidents, such as rats gnawing wires, broken ground wires, aging wires and so on.
