What to Look For in a Commercial Espresso Machine When you are looking to purchase a commercial coffee machine, there are many things to take into consideration. Your cafe's volume, intended use of the service and barista's knowledge will determine which espresso machine is right for your business. A double boiler system allows you to brew while steaming. It also reduces recovery time between pulls. Proportional-integral-derivative (PID) temperature control manages on/off cycles for optimal boiler temperatures. Productivity A commercial espresso machine can handle a greater amount of coffee than a home machine. A domestic espresso machine to function in a professional setting would be the recipe for disaster. A commercial machine that is of high quality can serve up to 100 cups of coffee per hour at peak times. This can be an enormous help in busy workplaces, since it prevents employees from having to wait around to get their coffee. The presence of a coffee maker in the workplace can allow workers to connect with one another. Often, teams of employees take turns getting the coffee for each other and this can help encourage collaboration and teamwork in the workplace. A coffee bar can help new employees feel more at ease in the workplace and break down the barriers between them, the senior employees and other employees. Commercial espresso machines are available in various sizes to cater for different needs. Some models are completely automatic, while others allow you to pre-program espresso shots so that the operator does not have to guess the right size of each shot. This is especially important for businesses with untrained baristas as inaccurate shots can greatly affect the intensity and flavor of espresso brewed. In addition, it's recommended to purchase ethically sourced and manufactured commercial espresso machines that benefit the communities in which coffee is grown. This will ensure that the product is of high quality and reduce the negative impact on the environment. Safety Espresso machines can cost as much money as a mini-car. They're also built to pump out a multitude of shots and drinks in an entire day. This high volume operation can cause unique risk to health and safety for workers, so it's crucial to think about the potential dangers that come with a commercial espresso machine. Be aware that commercial espresso machines tend to use warm water. This can encourage the growth of bacteria. Inefficiently maintained machines that are not descaled and cleaned regularly will accumulate spent espresso. This can cause it to turn rancid, and potentially cause illness when consumed by customers. A commercial espresso machine that has steam wands without an effective seal may allow for bacterial growth within the milk frothing process, as it may not be able temperatures high enough to eliminate all bacteria. When deciding on the best commercial espresso machine, it's important to consider the type of beverages you'll be serving and how many cups per hour your space can hold. You should also look for a machine that offers automation features that make it faster and easier to serve your patrons their favorite coffee drinks. Additionally, look for a guarantee that covers parts and labor so that any technical issues can be solved quickly and efficiently. Energy Efficiency Commercial espresso machines require considerably more power than home models. coffee espresso machines are more heavy and have larger boilers that can support multiple group heads for standard cafe production. These machines also operate at a more elevated temperature and are usually located in an indoor setting (such as cafes or restaurants) where the electronic components can overheat rapidly, leading to machine failure. The boiler of a commercial espresso machine is heated and holds the pressurized water, which is supplied by an electric pump. This water is then used for brewing and steaming espresso. The boiler consists of multiple copper tubes that are heated by electric elements. When the brew sensor determines that the water level is at the desired level the solenoid valve opens and fills the boiler with fresh water. The heating element is then turned off. There are four kinds of espresso machines, distinguished by their capacity to steam and brew: the TB (brewing only), TX (twin boilers) HX, DA (double automatic). TB and TX machines provide stable brewing temperatures, while DA offers rapid steaming from one boiler. HX machines are used by many cafes as they are the best in both steam and brew temperature. Maintenance Commercial espresso machines need regular maintenance as do cars. They require regular maintenance to work efficiently and smoothly. If you make the effort to keep your machine in top condition, it will provide you better tasting coffee and last longer. It's an everyday ritual to clean your espresso machine, however you should also be aware of those parts that require more thorough cleaning. There will be leftovers from coffee grounds and other milk products that could cause the machine to breakdown over time. Regular cleaning can help prevent this and keeps your espresso machine operating at to its maximum. Most commercial espresso machines require descaling every three months. This process requires a few additional steps compared to normal cleaning. You'll want review the manual to ensure that you follow all the instructions. Descaling involves using a solution to dissolves the scale in the water tank. To complete this task you'll need to place a container under the steam wand or, in certain models, under the coffee spouts. Follow the steps for your particular model. A water filter change is an additional maintenance process. This is something that can be easily forgotten but is essential to remember so that you don't get a build-up of mineral deposits. It is also important to look for calcification within the spray head, which can be difficult to get rid of.
