What to Look For in a Commercial Espresso Machine There are a variety of factors to consider when purchasing a commercial espresso machine. The type of espresso machine appropriate for your cafe will depend on the volume and the purpose for which it is used, and barista skills. A double boiler system allows you to steam while brewing. This cuts down on the time to recuperate between pulls. Proportional-integral-derivative (PID) temperature control manages on/off cycles for optimal boiler temperatures. Productivity A commercial espresso machine is designed to handle a larger amount of coffee than an espresso machine at home. The idea of allowing a home espresso machine to work in a professional setting would be a recipe for disaster. A commercial machine of top quality will be able to serve up to 100 coffee cups in an hour during peak times. This can be an enormous help in busy offices, as it will stop employees from waiting around to get their coffee. Coffee machines can aid workers in bonding. Sometimes, teams of people make a habit of getting coffee each other, and this can foster collaboration and teamwork in the workplace. A dedicated coffee area could make new employees feel more at ease in their workplace and break down barriers between them, the senior employees and other workers. Commercial espresso machines come in various sizes to meet different needs. Certain models are fully automated and others are able to pre-program espresso shot sizes so that the operators do not have to guess the correct size. This is especially important for companies that employ untrained baristas since incorrect shots can alter the intensity and taste of espresso. It is also best to purchase commercial espresso machines that are made of ethically sourced products that benefit the communities in which coffee beans are cultivated. This will ensure a high quality product and minimize the negative impact on the environment. Safety Espresso machines can cost as much as a car that is compact. They're also designed to churn out a multitude of drinks and shots throughout the course of a day. The high volume of operations create unique risk to health and safety for staff members, so it's important to take into account the potential risks that come with an espresso machine in a commercial setting. Be aware that commercial espresso machines are more likely to utilize warm water. This can encourage the growth of bacteria. Poorly maintained machines that are not descaled and cleaned regularly can build up spent espresso. This can cause it to go rancid, and possibly cause illness when consumed by customers. A commercial espresso machine that has a a steam wand that is not sealed could allow bacteria to flourish in the milk the frothing process. Think about the kind of beverage you will be serving and how many cups an hour can be served when selecting a commercial coffee machine. You'll also want an espresso machine that has automated features, which makes it much easier and quicker to serve your customers your favorite coffee drink. Also, look for a warranty that covers parts and labor, so that any technical issues can be dealt with quickly and efficiently. Energy Efficiency Commercial espresso machines require significantly more power than the home models. This is because professional espresso machines are built with heavier frames and large capacity boilers that can handle the numerous group heads required for standard cafe production. These machines also operate at a much greater temperature at ambient temperatures and are typically in an indoor space (such as cafes or restaurants) where the electronics could overheat quickly resulting in machine failure. The boiler of a commercial espresso machine heats and stores the pressurized water, which is supplied by an electric pump. This water is then used to brew and steaming espresso. The boiler is comprised of several copper tubes that are heated by electric elements. When the brew level sensor detects that the water has reached its goal level the solenoid valve is opened to allow the boiler to be filled with fresh water and the heating element turns off. There are four distinct types of espresso machines. They are distinguished by the way they can be brewed or steamed by using the TB (brewing-only), TX (twin-boilers), HX (double automated), and DA (double automated). TB and TX machines have stable brew temperatures, while DA can provide rapid steaming using the use of a single boiler. Many cafes are switching to HX machines, as they have been proven to provide the best of both worlds in terms of steam and brew temperatures. Maintenance Commercial espresso machines require regular maintenance, just like cars. They require regular maintenance to operate efficiently and smoothly. If you maintain your machine, you will enjoy a better-tasting coffee and it will last longer. It's a routine to clean your espresso machine, but you should be aware of the parts that need an extra clean. There will be leftovers from coffee grounds and other milk products that could cause the machine to degrade over time. Regular cleaning helps prevent this from happening and helps keep your espresso machine working at the best it can. Most commercial espresso machines need descaling every three months. This process requires a few extra steps when compared to normal cleaning. It is recommended to review the manual to ensure that you follow all the steps. The solution used to decal the water tank disintegrates the scale. To complete this task it is necessary to put a container under the steam wand and, in some units, under the coffee spouts. Follow the directions specific to your model. A water filter change is another maintenance step. This is something that could easily be forgotten however it's essential to remember so that you don't build up of mineral deposits. It is also important to look for calcification within the spray head, which can be difficult to remove.
