Coffee maker (coffee pot) introduce the history of coffee pot

The history of the coffee pot

Coffee pot is one of the earliest inventions in Europe. It was invented in France around 1685 and spread widely during the period of Louis XV. It's just a glass water bottle with a heating metal plate and an alcohol lamp underneath. Because this kind of coffee pot was very time-consuming, American Benjamin Thompson invented the Langford filter coffee pot, which was very popular at that time.

In 1763, the Frenchman Don Madan invented to put the crushed coffee beans into a flannel pocket and hang them on the edge of the pot. After injecting hot water, the coffee in the bag was heated for a long time to produce different forms of cooking, which greatly improved the aroma of the coffee.

In 1800, the Archbishop of Paris de Belo invented a pot-type coffee heater divided into two stages, designed to keep the aroma of coffee from overflowing, and can be said to be the ancestor of today's trickle coffee pot. The pot places the ground coffee in a hole-shaped container at the top of the coffee pot, from which hot water is injected, and the water flows through these small holes to the bottom of the coffee pot. It is characterized by the use of cold water to quench, at the rate of 40 drops per minute, a drop to slowly absorb the essence of coffee. Due to the extremely slow speed, coffee powder with extremely fine grinding should be selected for extraction. The coffee brewed in this way is extremely low in caffeine and tastes particularly refreshing.

In 1840, Nabel, a British marine engineer, invented the siphon coffee heater. This kind of heater is designed according to the reason that when the water boils, the air pressure in the container of coffee powder decreases, so it automatically absorbs boiling water into the coffee. And this is the predecessor of the Belgian royal coffee pot.

Types of coffee pots

There are three types of electric coffee pots: percolation type, drip type and vacuum type. The percolation coffee pot is the early product of the electric coffee pot, although the price is low, but it is not convenient to use and the reliability is poor. The coffee made by the vacuum electric coffee pot has a strong flavor, but its structure is complex and prone to failure. The fittest survive, and now the only thing left on the market is the drip-type electric coffee maker.

Although there is only one type of electric coffee maker in general, there are ordinary coffee pots that are only used to make coffee powder, two-in-one coffee makers that can grind coffee beans themselves, and Italian steam coffee pots that can make milk bubbles. If you are a 9-to-5 office worker with limited time, a cheap ordinary coffee maker is a good choice, and if you have reached the level of "fever", then the mellow smell of your own ground coffee powder and charcoal-roasted coffee with a beautiful head of milk foam and delicious cinnamon powder will certainly be your best choice.

Coffee pot selection and purchase

In terms of specifications, the power of the household electric coffee maker is less than 1000 watts, the capacity is 0.5m / 0.8 liter, and it can make 480 cups of coffee. If you often entertain friends or family, you can also choose a larger capacity, but it is best not to exceed 1.5 liters.

From the quality point of view, the appearance of the electric coffee pot should be a color coordination, the production of fine arts and crafts, the damage of various parts, rough are not allowed, the bottom of the kettle is not leaking is the minimum requirement.

Coffee pot use

You can't burn it empty. Like most kitchen appliances, the electric coffee pot cannot be burned empty. It must be filled with water and coffee before turning on the power. Never turn on the electricity in the empty pot. When brewing coffee, you should always pay attention to the water level in the pot. If the water is about to dry up, you should cut off the power supply in time, otherwise the pot will be burned out.

Be waterproof. The electric coffee pot should not be dry-fired and should not add too much water, otherwise the water will overflow and wet the electric heating element after boiling. At the same time, do not splash water on the electrical parts of the kettle body when adding water, so as not to reduce the insulation performance. When cleaning the coffee pot, the pot body can not be directly immersed in water, but to remove the filter, filter cleaning, other parts had better be wiped with a clean soft cloth.

Remove dirt regularly. Before using the electric coffee pot for the first time, you should boil two pots of boiling water to remove the bad smell. In the future, the scale should be removed 2-5 times a year according to the use.
