What to Look For in a Commercial Espresso Machine There are a myriad of aspects to consider when buying a commercial espresso machine. Your cafe's volume, intended use for service, and barista's experience will determine which type of espresso machine is right for your business. A double boiler system provides the ability to brew as well as steam simultaneously. This cuts down on the time to recover 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 much more volume of coffee than an espresso machine at home. A domestic espresso machine would not be effective in a professional environment. A high quality commercial machine will be able to serve up to 100 cups of coffee per hour at peak times. This is an enormous benefit for busy workplaces by preventing employees from waiting for hours to get their coffee. Having a coffee machine in the workplace can help workers to bond with one another. Teams of employees often are able to take turns ordering coffee for one another, which could encourage collaboration and teamwork in the workplace. A dedicated space for coffee is also a great way to assist new employees to feel at comfortable in the workplace, removing any barriers between them and the senior staff members. Commercial espresso machines are available in a variety of sizes to meet different needs. Some models are fully automatic and some can be programmed with pre-programmed espresso shot sizes so that the operators aren't required to guess the correct size. This is particularly important for companies that employ untrained baristas as incorrect shots can alter the intensity and taste of espresso. It is also advisable to purchase commercial espresso machines that are made of ethically-sourced materials that support the communities in which coffee beans are harvested. This will ensure a premium quality product, and reduce the negative impact on the environment. Safety Espresso machines can cost as much money as a mini-car. They are designed to create hundreds of shots and drinks in the course of a single day. Commercial espresso machines can present unique health and safety risks to employees due to their high volume. It is important to keep in mind that commercial espresso machines are likely to run on warm water, which could contribute to the growth of bacteria. Inefficiently maintained machines that are not cleaned and descaled regularly can build up spent espresso. This could cause it to go rancid, and potentially cause illness when consumed by customers. Commercial espresso machines with a steam wand that is not sealed can let bacteria grow in the milk that is frothing. When you are choosing the best commercial espresso machine, it is important to think about the type of beverages you'll be serving as well as the amount of cups per hour your space can handle. You should also look for an espresso machine that has automated features, which makes it much easier and quicker to serve your customers your favorite coffee drink. In addition, look for a guarantee that covers parts and labor so that any technical issues are addressed quickly and effectively. Energy Efficiency The power requirements for commercial espresso machines are considerably higher than home models. This is due to the fact that professional espresso machines are built with heavier frames and large capacity boilers to support the multiple group heads needed for standard cafe production. These machines also operate at a greater temperature at ambient temperatures and are typically in an indoor setting (such as a restaurant or coffee shop) where the electronic components can overheat quickly resulting in the machine breaking down. The boiler of an espresso machine designed for commercial use heats up and holds water that has been pressurized with an electric pump. This water is used to brew and steam espresso. The boiler is made up of several copper tubes that are heated by electric elements. When the brew level sensor determines that the water has reached its desired level the solenoid valve opens to fill the boiler with water that is fresh and the heating element turns off. There are four types of espresso machines that are distinguished by their ability to steam and brew: TB (brewing only), TX (twin boilers) HX, DA (double automatic). TB and TX machines provide stable brew temperatures, whereas DA offers rapid steaming using one boiler. Many cafes are switching to HX machines, as they have been shown to offer the best of both worlds, in terms of brew and steam temperatures. Maintenance Commercial espresso machines need regular maintenance similar to cars. They need to be maintained to work efficiently and smoothly. If you take the time to maintain your machine in good condition, it will provide you a more delicious coffee and last longer. Cleaning your espresso machine is an everyday ritual, but it's important to also clean some parts on a more fundamental level. There are traces of coffee grounds and other milk products that could cause the machine to break down over time. Regular cleaning will keep your espresso machine in good condition. Most commercial espresso machines need descaling every three months. espresso maker requires a few more steps than normal cleaning, so it's best to review your manual to ensure you're following all the directions. Descaling is the process of using a solution that dissolves scale in the water tank. You'll require a container to finish this task. In some units you may also require a container beneath the coffee spouts. Follow the instructions for your particular model. A water filter change is another maintenance task. It's easy to forget however it's important to avoid accumulating mineral deposits. Look for calcification, which is difficult to get rid of in the spray head.
