The volume of your cafe, the intended use of the service and barista's knowledge will determine which espresso machine is best for your business. A double boiler system gives the ability to brew and steam simultaneously. It also reduces recovery time between pulls. Proportional-integral-derivative (PID) temperature control manages on/off cycles for optimal boiler temperatures. espresso machines for home is designed to handle a much more volume of coffee than an espresso machine at home. A domestic espresso machine would not perform well in a professional environment. A commercial coffee machine of good quality can serve up to 100 cups of coffee every hour during peak hours. This can be a great help in busy offices, as it keeps employees from having to wait around to get their coffee. A coffee machine can also aid workers in bonding. Oftentimes teams of people will make a habit of getting coffee, and this can encourage teamwork and collaboration in the workplace. A coffee bar can help new employees feel more at ease at work and reduce the barriers between them, senior employees and other employees. Commercial espresso machines are available in various sizes to meet a variety of requirements. Some models are purely automatic and others can pre-program espresso shots so that the operator does not have to guess the right size of the shot. This is particularly important for companies that employ baristas that aren't properly trained, as inaccurate shots can impact the strength and taste of espresso. It is also advisable to purchase commercial espresso machines that are made of ethically-sourced materials that support the communities where coffee beans are cultivated. This will ensure that the product is of high quality and minimizes the negative impact to the environment. Safety Espresso machines can cost as much as a car that is compact. The machines are designed to produce hundreds of shots and drinks in one day. The high volume of operations cause unique risk to health and safety for staff, so it's important to take into account the risks that could be associated with an espresso machine in a commercial setting. It's important to bear in mind that commercial espresso machines are likely to operate with warm water, which can increase the growth of bacteria. A machine that is not maintained properly and hasn't been cleaned or descaled regularly can start to build up spent espresso, which could turn rancid and could potentially cause illnesses if consumed by consumers. A commercial espresso machine that has a steam wands that are not sealed could allow bacteria to grow in the milk foaming process. When deciding on an espresso machine for commercial use, it's important to consider the type of beverages you'll be serving as well as the amount of cups per hour your space can accommodate.

Find a warranty that includes both labor and parts. This will ensure that any technical problems will be solved quickly. Energy Efficiency Commercial espresso machines require significantly more power than the home models. Professional espresso machines weigh more and have larger boilers that can support several group heads for regular cafe production. These machines operate at a higher temperature, and are usually located indoors (such as in a cafe or restaurant) where the electronics could overheat. The boiler of an espresso machine for commercial use heats and holds water which has been pressurized using an electric pump. This water is used to brew and steam espresso. The boiler is made up of a number of copper tubes that are heated by electric elements. When the brew level sensor senses that the water has reached its target level the solenoid valve opens to fill the boiler with water that is fresh and the heating element is turned off. There are four kinds of espresso machines, differentiated by their ability to brew and steam the water: The TB (brewing only), TX (twin boilers) HX, TB, and DA (double automatic). TB and TX machines have stable brew temperatures, whereas DA offers rapid steaming using a single boiler. Many cafes are switching to HX machines since they have been proven to provide the best of both worlds, in terms of brew and steam temperatures. Maintenance Like cars require routine tune-ups commercial espresso machines require maintenance to continue working smoothly and efficiently. If you maintain your machine, you will enjoy a better tasting coffee and it will last longer. Cleaning your espresso machine is an everyday ritual, but it's vital to clean certain components at a deeper level. There will be residues from coffee grounds and other milk products that can cause the machine to fail over time. Regular cleaning will keep your espresso machine in great condition.

This is something that could be easily forgotten however it's essential to remember so that you don't get a build-up of mineral deposits. Check for calcification, which can be difficult to remove in the spray head.
