In order to pursue long-term cooking stability, most friends will spend a lot of money to buy electric bean grinder (electric mill for short), the main reason is that they do not want to be bothered by too much fine powder in the hand bean mill!

Secondly, the reason for buying electric mill is not only to ensure the stability of grinding quality, but also to make it easier, such as omitting the process of energy-consuming hand grinding. You just need to find the bean mouth and flour outlet and put the bean switch on and off. However, there are still some details to pay attention to in the use, because if you do not pay attention to it, the loss of the bean grinder will be much faster than expected. For example, a question asked by a friend who arrived at the store today: "Why do you always start the machine and then put in the beans every time you grind the coffee beans? isn't it the same vice versa?" Good question! Because this is a major point of the details of the electric mill!

Why should we start the grinding of beans first and then put down the beans? This is mainly a detail that needs to be paid attention to in the use of single bean grinder! If the order of the two is changed: first put the beans and then start the machine for grinding, it will be easier to damage the cutter head!

It takes a certain amount of time for the machine to start, just like when the vehicle starts to increase speed, it will not reach the target speed in an instant! The same is true when it comes to an electric mill, even if it's only for a short second. When we start the bean grinder, it takes about 0.5 seconds for the cutter head to rotate stably. If the coffee beans are put in before that, the coffee beans will be in the gap between the cutters, adding a certain amount of resistance to the start-up of the bean grinder. The impact of these resistance will be on the knife head. At the beginning, due to sufficient power and sharp cutterhead, it will not cause much impact! However, with the increase of the number of times and time, the wear shortcomings of the cutter head begin to appear. Wait until some bad luck, when the knife head meets the beans with high hardness, the bean grinder may be stuck and shut down! But this kind of situation mostly occurs in the household small electric mill with insufficient power and low rotational speed.

Therefore, Qianjie will recommend friends who use electric grinding to start the machine when preparing to grind coffee beans, and then pour the beans into the grinding machine when the bean grinder is running stably, which can reduce the loss of the cutter head and reduce the probability of failure.

Regular cleaning is also very important like yesterday's coffee machine cleaning, bean grinder cleaning is also very important, proper cleaning and maintenance is the best way to prolong service life! But the electric mill is not as easy to disassemble and clean up as the hand mill, so we can divide the cleaning of the bean grinder into daily and regular aspects, which only requires simple cleaning and a deep cleaning for a long time. Daily cleaning: when we have finished our daily use, we can blow air at the inlet and outlet of the bean grinder. Because there must be a certain degree of coffee powder left in the dead corner space in the grinding bin (this is why the bean grinder is always "washed" before use), the purpose of blowing is to blow these residual particles out of the warehouse.

But pay attention to safety, it is best to lose power, or make sure the bean grinder is not started before cleaning! Regular cleaning: blowing can only blow away the coffee particles that remain in the warehouse without stickiness, while some sticky particles and grease are substances that cannot be blown away by air! So we need to take the machine apart and clean it deeply.

The specific operation of the machine needs to consult the corresponding customer service of the electric mill, or the instructions ~ after taking apart the bean grinder, take out the cutter head and clean it with clean water, and then wipe it dry quickly! By the way, wipe the other edges and corners of the grinding bin with a clean dishcloth, and then assemble them back. If the hands-on ability is not so strong friends do not need to worry, the bean grinder also has a special cleaning film like the coffee machine. The specific operation is to directly grind the cleaning piece as coffee beans, it will carry out the residual substances in the cutter head during the grinding process, and the cleaning frequency can be kept at 1-2 months.
