Coffee machine pump pressure 15 and 20, in-depth discussion of their differences

The difference between a coffee machine with a pump pressure of 15 and a pump pressure of 20 lies in the extraction efficiency and taste experience. When the pump pressure is 15, the coffee extraction speed is slower, the coffee concentration is lower, and the taste is softer, which is suitable for people who like softer tastes. When the pump pressure is 20, the extraction speed is faster, the coffee concentration is higher, the taste is richer, and it has more layers and changes. The choice of pump pressure depends on personal taste preferences and coffee bean characteristics. In-depth discussion of this difference will help coffee lovers better master the operation skills of coffee machines and improve coffee quality.

In the world of coffee machines, the importance of pump pressure is self-evident. Whether for home users or professional baristas, understanding the difference between a coffee machine's pump pressure of 15 and 20 can help us better understand how coffee machines work and how they affect the final coffee quality.

1. Brief description of pump pressure 15

The working pressure of a coffee machine with a pump pressure of 15 is set at around 15 atmospheres. This pressure level is sufficient for most home and entry-level commercial coffee machines. Under this pressure, water flows through the coffee powder layer at a faster speed through the action of the pump to extract the soluble substances in the coffee. Due to the moderate pressure, the coffee produced by this type of coffee machine has a balanced taste and is suitable for most people's tastes. Due to its relatively simple operation and low maintenance cost, it is deeply loved by many users.

2. Characteristics of Pump Pressure 20

The coffee machine with a pump pressure of 20 has a higher working pressure, reaching 20 atmospheres. This high pressure allows water to penetrate deeper into the coffee powder, thereby extracting more coffee essence. This means that compared with a pump pressure of 15, the coffee made by a coffee machine with a pump pressure of 20 is richer and has a richer taste. The high pressure can also bring more delicate foam, providing good conditions for making high-quality latte, cappuccino and other milky coffees. However, correspondingly, due to the increase in pressure, the operation difficulty will also increase, and the technical requirements for the barista will be higher.

3. Comparison between the two

1. Different application scenarios : Coffee machines with a pump pressure of 15 are more suitable for home and entry-level commercial occasions, while coffee machines with a pump pressure of 20 are more often used in professional coffee shops or high-end commercial occasions.

2. Difference in taste : The coffee produced by the coffee machine with a pump pressure of 15 has a balanced taste and is suitable for the general taste; the coffee machine with a pump pressure of 20 can produce a richer coffee with a richer taste.

3. Technical requirements : Due to the higher pressure of the coffee machine with a pump pressure of 20, the technical requirements for the barista are also increased accordingly, and a certain amount of operating experience is required to maximize its effectiveness.

4. Maintenance and cost : The maintenance cost of a coffee machine with a pump pressure of 15 is relatively low due to its moderate pressure, while the maintenance of a coffee machine with a pump pressure of 20 may be slightly more complicated due to its high-pressure system, and the cost will increase accordingly.

The coffee beans and grinding fineness used in the coffee machines under the two pressures also need to be adjusted accordingly to ensure the best extraction effect.

IV. In-depth discussion

With the development of science and technology, the pump technology of coffee machines is also constantly improving. We may see more advanced pump technology applied to coffee machines, making the taste of coffee richer and more diverse. As consumers' requirements for coffee quality continue to increase, the choice of coffee machine pump technology will also become more diversified.

The coffee machine pump pressure of 15 and 20 has its own characteristics. Which one to choose depends on the user's needs, budget and technical level. For coffee lovers, understanding these differences will help us better enjoy the wonderful experience brought by coffee.
