Is the water in the coffee machine drinkable? Is the coffee maker boiler hot water harmful to the body?
Friends who intend to make coffee machines must know that coffee machines have a group of things called "hot water pipe, hot water pipe switch", the function is to release hot water in the coffee machine boiler.
I often see many people use this set of parts of the coffee machine to release hot water from the boiler in the machine for tea, warm cups, washing appliances, direct drinking, making other milk tea products... the reason is a "convenience". Because the coffee machine supplies hot water at any time, the coffee machine boiler comes with a temperature probe, and when it is lower than the set temperature, the coffee machine will automatically heat up. It is precisely because of automatic heating, it forms the repeated boiling of water, even if a coffee machine does not dry anything a day, it must be repeatedly heated dozens of times, so that water is repeatedly boiled dozens of times.
But have you ever thought about how much harm it would do to your health and property if you used this set of parts regularly?
First, let me tell you about the dangers to your body:
According to experimental proof, if water is repeatedly boiled, it will change the "nitrate" in the water into "nitrite", and "nitrite" will make the hemoglobin in the human body become "nitrite hemoglobin", which will make the red blood cells lose their function of carrying oxygen.
Therefore, if you drink repeatedly boiled water regularly, it may cause tissue hypoxia, shortness of breath, chest tightness, purple lips and nails, or easy drowsiness. If it is more serious, after the "nitrite" enters the body, it is likely to be converted into a carcinogen "nitrosamine" through the action of stomach acid.
Do you understand?
The danger to property is to reduce the service life of coffee machines! The water treatment is better (did not see a few cafes pay special attention to water), the water is not good, support dead, at most, 5 years! Good water quality plus good maintenance at ordinary times can be extended to 8 years, 10 years! Water ~~~
Generally our tap water is hard water, calcium and magnesium ions in hard water can make coffee machine boiler, pipeline, valve...... generate thick scale, thus blocking, failure, necrosis, repair is able to repair, loss You can buy a new ~~~!!
Also, if you are making coffee, put hot water in the boiler, it will have a great impact on the temperature stability of the coffee machine, affecting the quality of coffee!

The Myth about the taste of Coffee-- discussion on the astringency in Coffee
The acidity of the cups made by the students is somewhat strong, and the acidity seems to be dissociated from the bitter taste, and the overall balance is greatly reduced, and it is mainly strong bitterness after the acid. At this time the problem came out several cups she felt obviously astringent taste, and I always think that this is not astringent taste but a combination of strong acid and bitter taste of a sour thorn. Explain for a long time, but I still can't.
