What to Look For in a Commercial Espresso Machine When you are looking to purchase a commercial coffee machine, there are a variety of factors to take into account. Your cafe's volume, intended use of the service and barista's knowledge will determine which espresso machine is ideal for your business. Double boilers allow you to brew while steaming. 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 larger amount of coffee than a home espresso machine. If you expect a home espresso maker to function in a professional space would be an unintentional recipe for disaster. A commercial machine that is of high quality will be able to serve up to 100 cups of coffee per hour during peak hours. This can be a lifesaver in busy workplaces, since it will stop employees from waiting around to get their coffee. Coffee machines can help workers bond. Teams of people usually take turns getting coffee for one another, which could facilitate collaboration and teamwork within the workplace. A dedicated coffee area can make new employees feel more at ease in the workplace and break down the barriers between them, senior employees and other employees. Commercial espresso machines come in various sizes to accommodate different requirements. Some models are entirely automated and others are able to program espresso shots in advance so that operators do not have to guess the proper size of the shot. This is especially crucial for businesses with baristas that aren't properly trained, as inaccurate shots can impact the strength and taste of brewed espresso. In addition, it's best to purchase ethically-sourced and manufactured commercial espresso machines which support the communities in which coffee is produced. This will ensure a top quality product and reduce the negative impact on the environment. Safety Espresso machines are large, heavy pieces of equipment that can cost as much as a new compact car. They're also designed to crank out hundreds of drinks and shots over the course of the day. Commercial espresso machines can pose unique health and safety risks to staff due to their large volume. It's important to keep it in mind that a commercial espresso machine is likely to run on warm water, which can increase the development of bacteria. A machine that is not maintained properly and isn't cleaned or descaled regularly can start to build up spent espresso, which could become rancid and cause illnesses if consumed by consumers. A commercial espresso machine that has steam wands without an effective seal can also allow for bacterial growth within the milk frothing process, since it might not be able temperatures that are sufficient to eliminate all bacteria. Take into consideration the type of beverage you will serve and how many cups an hour your space can handle when selecting a commercial coffee machine. You'll also want machines that have automation features, which make it simpler and quicker to serve your customers their favorite coffee drink. You should look for a guarantee that includes both labor and parts. This will ensure that any technical problems will be solved quickly. Energy Efficiency The power requirements for commercial espresso machines are significantly higher than those of home models. This is because professional espresso machines have larger frames and large capacity boilers to handle the multiple group heads needed for standard cafe production. These machines also operate at a higher ambient temperature and are often located in an indoor location (such as cafes or restaurants) where the electronics may quickly overheat, resulting in malfunctioning machines. The boiler of a commercial espresso machine provides heat and storage for pressurized water supplied by 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 sensor determines that the water level has reached the desired level the solenoid valve opens and the boiler is filled with new water. The heating element is then shut off. There are four kinds of espresso machines, differentiated by their capacity to brew and steam with steam: TBS (brewing only), TX (twin boilers) HX, DA (double automatic). TB and TX machines offer stable brew temperatures, while DA allows rapid steaming from a single boiler. Many cafes are converting to HX machines, as they have been proven to offer the best of both worlds in terms of steam temperature and brew temperature. Maintenance Commercial espresso machines require regular maintenance similar to cars. They require regular maintenance in order to run smoothly and efficiently. If you make the effort to maintain your machine in good condition, it will provide you a better tasting coffee and last longer. It's a routine to clean your espresso machine, but you should pay attention to the parts that need an extra clean. There will be traces of coffee grounds and other milk products that could cause the machine to degrade over time. Regular cleaning will keep your espresso machine in top condition. The majority of commercial espresso machines require descaling at least every 3 months. This procedure requires a few more steps than regular cleaning, so it's best to review your manual to ensure that you're following the instructions.

Another step in maintenance is changing the water filters. This is a step that can easily be overlooked, but it's important to remember so that there isn't a build-up of mineral deposits. Also, you should look for calcification within the spray head, which is difficult to eliminate.
