The difference between the vibration pump and rotary pump of the coffee machine

First, vibrating pump and rotary pump are two common coffee machine pumps, what is the difference between them? Simply put, the vibration pump is controlled by an electric oscillator with a certain elasticity of the thin metal plate to produce vibration, so as to pump water through the piston drive. A rotary pump, on the other hand, uses an electric motor to create a rotational force that presses water through a centrifugal impeller and into the coffee machine. The principles of the two pumps are different, which also leads to differences in their use.

Second, the impact of vibration pump on the flavor of coffee

1. Unstable water temperature

Vibration pump drive water movement is not smooth enough, through the shock produced by the pumping process will make the water temperature fluctuate up and down significantly. This unstable water temperature will have a negative impact on the coffee, especially on light roasted coffee that requires precise temperature control and brewing methods that require long extraction times.

2. Lack of layered coffee flavor

Third, the impact of the rotary pump on the flavor of coffee

Due to the lack of uniformity in the pumping of the vibration pump, the coffee bed will not be even enough during brewing, resulting in insufficient volume of part of the coffee creamer, a single taste and a lack of layered sense.

1. Temperature stability

As the rotary pump pumps water through the impeller, its pumping speed is very stable, making it easier to maintain the water temperature in the coffee machine at a constant temperature, thus making the coffee in the brewing process to maintain a stable temperature, increasing the complexity of the coffee aroma and taste.

2. More uniform infiltration and rinsing

As the rotary pump can provide higher water pressure, the coffee bed can be more evenly infiltrated and rinsed, producing more coffee oils and cream, making the coffee taste more intense.

In short, the difference between a vibratory pump and a rotary pump has a significant impact on coffee flavor. Choosing the right coffee machine is more important than the choice of coffee beans.
