About Italian Delong Delonghi

De'Longhi, Delon, one of the major small electrical manufacturers in Italy, was founded in Treviso, Italy in 1902, from a manual workshop. In the 1950s, Delong Group was officially established, mainly supplying heating system parts to other companies. In the 1970s, the company began to launch its own brand products.

DeLonghi, which originated in Italy, was founded in 1902 and began to grow up as a handicraft workshop. In the 1950s, Delong Group was officially established, but its business scope is mainly to supply heating system parts for other companies. In the 1970s, the company was a major turning point in Delong's history, and the company began to introduce its own brand products to the market. Now it has become a multinational group in the design, R & D, production and sales of medium-and high-grade household appliances. Its products cover many fields: coffee machine series, kitchen appliances series, heating appliances series, air conditioning / air purification series, cleaning / ironing series, business in more than 80 countries around the world. In 2005, with the continuous enhancement of the group's business confidence in the Chinese market, Delong Jianwu China was established, which is really involved in the business operation of the Chinese market and is committed to providing better products and services to Chinese consumers. it also makes Delong a synonym for good design, high-end quality and fashion life.

Introduction to the model of Delong coffee machine

The types of coffee machines sold on the market mainly include fully automatic, semi-automatic, dripping type, pump pressure type, steam type and so on.

The most important feature of the automatic coffee machine is its convenience. Coffee beans can be made into espresso at the touch of a button, releasing the aroma of freshly brewed coffee; almost all functions can be customized to produce espresso, cappuccino, latte and macchiato with the best export flavor. At present, most of the coffee beans and coffee powder of the fully automatic coffee machine on the market can be used, and it is more convenient to grind, fill powder, press powder, filter, boil and clean with one button. In terms of the price of the market, the price of the automatic coffee machine is relatively high. If it is a coffee machine with other flavor functions, please climb to a higher floor.

The semi-automatic coffee machine can provide coffee with different tastes by choosing the amount of powder and the strength of the powder. The fully automatic coffee machine provides users with convenience in operation, but the coffee taste may not be as good as the semi-automatic coffee machine with manual filling and pressing powder. Relatively speaking, the price of semi-automatic coffee machine is cheaper than that of full automaton.

Drip coffee machine is a classic drip filter. Simple, efficient, reliable, suitable for public use. The working principle of the drip coffee machine is also relatively simple. It contains a funnel for holding filter paper and coffee powder. It is essential to have a device for filtering coffee. If you choose to use a drip coffee machine, you have to buy filter paper. Under the leak, there is a hose deep into the water box of the coffee machine, sucking the boiling water out of the water box and dripping into the coffee powder in the funnel. By slowly soaking, the filter paper will filter out the dregs and drip slowly into the coffee pot below.

The steam coffee machine is the principle of quickly soaking coffee powder with steam. The coffee brewed is lighter than the pump coffee, has no grease foam, has a higher temperature, and tastes heavier than the coffee brewed by the drip coffee machine.

High pressure steam coffee machine is a combination of pump type and steam type. The drip coffee machine mentioned above uses an atmospheric pressure when brewing coffee, that is, it is brewed under atmospheric pressure, while the pump coffee machine is based on the principle of pressure, and the water pressure when brewing coffee is greater than one atmospheric pressure. generally 5-19 atmospheric pressure, the coffee essence is extracted quickly, the coffee is fragrant and strong, and there will be a layer of grease foam.

Let's focus on the espresso machine, of which there are two most important points: pressure stability and temperature stability. Pressure stability requires commercial-grade rotary pumps, temperature stability requires alphabetical boilers or double boilers. The taste of espresso is mainly reflected in two points: extraction rate and concentration. The extraction rate determines whether the espresso liquid is too sour, too bitter and too much sundries relative to the coffee bean itself. The effect of concentration on taste is understood, so I won't explain it. Temperature and time determine the extraction rate, pressure and grinding degree determine the flow rate, and the flow rate and the final coffee volume determine the concentration and time. This is a complex system of variables, and countless different results can be obtained if all variables are not fixed. So people are used to fixing the temperature: about 92 degrees, fixed: the pressure is about 9 to 10bar, fixed: about 25 to 30 seconds, and then according to the coffee beans and personal taste to adjust the amount of powder and thickness, and then adjust the flow rate and the amount of coffee, so as to produce a cup of espresso with a specific taste. My humble opinion is that when the powder quantity and the scale conflict, we should first find the appropriate scale (coffee powder thickness), and then adjust the powder quantity to achieve a specific flow rate.

Performance of coffee machine

The performance of the coffee machine is divided into two situations. When the steam bubble function is not discussed, the temperature stable watershed of the household single-head coffee machine is around 5000 yuan nuova Oscar, which has a 1.8-liter mother-to-child boiler, which can be relatively easy to get a stable temperature that can be replicated. Models below Oscar have no essential difference in temperature stability, and it is difficult (not impossible) to obtain a stable and replicable cooking temperature. While the watershed of pressure stability is 6000mur7000 pieces of various brands of E61 head master boiler rotary pump coffee machines, they can obtain relatively stable pressure. In this regard, there is no essential difference between coffee machines lower than this price, they all use vibrating pumps, and the pressure can not be guaranteed to be stable. With regard to pressure, low-end household phones like to label 15bar, 20bar, etc., which refers to the water pressure at which it can output 15bar, rather than being stable at this pressure all the time. In terms of steam performance and function, the coffee machines with the worst and worst functions are undoubtedly those with plastic steam nozzles. This kind of coffee machine with plastic mouth is hard to make good foam no matter how skilled you are. Then there are some coffee machines with good functions but poor performance in the price of three or four thousand yuan, including but not limited to the famous 4000 yuan Lanchio silva and Huijia heating block series. The small boiler pie represented by silva not only has poor steam strength and humidity, but also needs to wait between coffee and steam function switching, so the function is poor. The steam performance of the heating block series is also not ideal, but it can make coffee and steam at the same time, the function is slightly stronger. In the next level, from the Nova Oscars of 5000 yuan to the Aibo double boiler coffee machine of more than 9000 yuan, all coffee machines with less than 3 liter steam boilers are difficult to have dry and strong steam. But it can also make delicate milk foam, which requires some technology. And compared with the big boiler multi-head machine, heating milk is very slow.
