Automatic coffee machine method of using the names of various parts of an Italian coffee machine
1. The coffee is too light: is this coffee machine an Italian professional steam coffee machine? The coffee machine has a reasonable price and belongs to Italian coffee utensils. The above scale is set according to the concentration of Italian coffee powder, while Italian coffee powder is very strong, when cooking other low concentration coffee powder? A rich taste can be obtained by adjusting the ratio of coffee powder to water. For example, after filling up the coffee powder gently, brew the coffee to the position of scale 2.
two。 Coffee temperature is too low: after turning on the power, wait for the water from the outlet to be hot before loading the coffee powder, or open the lid to heat it, and then close the lid when the water inside is about to boil, so that the coffee tastes hot.
3. Water comes out soon after turning on the power: is this a normal situation? Because the coffee machine boiler is very sealed, the water and the gas inside will expand after heating, and the water will be pressed out. After the water is hot, the coffee can be made, or the lid of the water opening can be opened and heated, which can avoid this phenomenon.
High pressure valve is a safety device, mainly to protect the safety of operators.
Main principle: when the water in the boiler is heated to produce pressure, and the pressure in the boiler reaches the preset 2bar, the valve will be opened and begin to relieve pressure, in order to avoid excessive pressure and exceed the pressure limit of the boiler itself.
Low pressure valve
A low-pressure valve is a valve set to maintain the normal operation of the coffee machine.
Main principle: avoid low pressure in the boiler caused by temperature drop and air volume contraction in the confined space. When reheating, the air expands faster than the temperature of the liquid caused by the heat conduction of the metal, which makes the pressure sensing element misjudge the pressure in the boiler and stop heating.
Discharge valve
The discharge valve is at the bottom of the boiler, mainly when turning on for a long time, keeping the water fresh, cleaning the scale in the boiler, and repairing the machine, all the water in the boiler needs to be removed. At this time, all the water in the boiler can be discharged by opening the discharge valve.
