1. Boiler capacity
When the boiler capacity is large, the effluent temperature is stable and the coffee quality is stable.
two。 Coffee machine temperature
Whether the temperature of the coffee machine remains stable or not also affects the quality of coffee.
3. Atmospheric pressure
It is ideal to make coffee with nine air pressure values.
4. Effluent temperature: the international standard coffee machine effluent temperature is 85 °C ~ 92 °C, which should also be adjusted according to the roasting degree of coffee beans. The deeper the roasting degree of coffee beans is, the lower the effluent temperature of the coffee machine will be, otherwise the extracted coffee is easy to produce scorched and bitter taste.
