Understand the functions and operation of the espresso machine.
An espresso machine is, quite simply, a hot water boiler and steam generator with one or more integrated, the pressure points of coffee brew. With the emphasis on maintaining the optimal temperature distribution, the machine designed for the production of 1-1,5 g of concentrated liquid coffee liqueur, forcing hot water at a temperature between 92-96 ° C at a pressure of 9 bar (130psi) for a period is between20-25 seconds.
Inside the machine
Boiler - A typical espresso machine semi-automatic or automatic operation consists of a boiler (or boiler), to produce hot water at about 96 degrees Celsius and steam at about 120 degrees. This is achieved by an electric heater and heat exchangers that transfer heat from the boiler's main fresh water, if necessary, to the point of delivery is achieved.
Pump - This removes water from the network (or integrated tank) and passes throughheat exchangers to the point of beer, the bar at a pressure of 9.
Electronic - Various electronic pressure and temperature and switches to ensure safe operation.
It is usually not every user has access to the inside of an espresso machine. This is due to high pressure and limited access to qualified technicians only.
Out of the car
Steam Valves - One or more tubes of steam drawn from the steam boiler at about 120 degrees andTerminating with a nozzle with 3 or more holes, in which jets of hot steam out of milk foam.
Hot water tap - This is used for the extraction of hot water at 96 degrees Celsius for more than the increase in espresso drinks.
Unit headquarters - are made of a scattering plate to break the flow of water and a rubber gasket. The seals of the filter handle to the head and prevents the water / coffee to filter out.
Handles Filter - Filter processes solid metal alloyfalling within the company and include the first coffee mill dry. The handles are equipped with single or double loops to prepare one or two cups at a time each.
Dials and indicators - pressure gauge pumps, boilers, water temperature and water levels at times.
Brewing - These keys are either predetermined (automatic) or on - off switches for controlling the duration of the brewing process and then the volume of beverage in the cup.
Drip Pan - ATray can be used to make a drain hole to collect what a small reservoir or drain.
Heated top compartment - a space used for storage cup. The cup warmer is simply due to the natural conduction of heat from the boiler is heated and has no independent source of heat. It is recommended that cups are mounted below the bottom (not the body), so that the bottom of the cup is heated, not the lip.
