What to Look For in a Commercial Espresso Machine There are a myriad of factors to consider when purchasing commercial espresso machines. barista espresso coffee machine of espresso machine that is suitable for your cafe will depend on the quantity, the intended use, and the barista's skill. A double boiler system allows you to steam while brewing. This reduces the time required 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 greater volume of coffee brewing than an espresso machine at home. The idea of allowing a home espresso machine to work in a professional setting could be an unintentional recipe for disaster. A commercial machine of high quality will be able serve up to 100 cups of coffee every hour during peak hours. This can be a great help in busy offices, as it stops employees from waiting for hours to get their coffee. The presence of a coffee maker in the workplace can assist workers in forming bonds with one another. Sometimes, teams of people be able to swap coffee for each other and this can encourage teamwork and collaboration in the workplace. Having a designated space to enjoy coffee can aid new employees in feeling at comfortable in the workplace, and break down any barriers between them and the senior employees. Commercial espresso machines are available in a variety of sizes to accommodate different needs. Some models are fully automatic while others have the ability to pre-program espresso sizes so that baristas aren't required to guess the right size. This is particularly crucial for businesses with inexperienced baristas as inaccurate shots can drastically affect the intensity and flavor of brewed espresso. It is also best to buy commercial espresso machines made of ethically-sourced materials that support the communities in which coffee beans are harvested. This will ensure a premium quality product and minimize the negative impact on the environment. Safety Espresso machines are massive heavy pieces of equipment that can cost as much as a new compact car. They are designed to create hundreds of shots and drinks in a single day. This high volume operation can result in unique health and safety hazards for employees, which is why it's important to consider the potential hazards that come with an espresso machine that is commercially used. It's important to bear in mind that commercial espresso machines are likely to run on warm water, which could aid in the development of bacteria. Machines that are poorly maintained and not descaled and cleaned regularly will accumulate spent espresso. This can cause it to go rancid and may cause illness when consumed by customers. A commercial espresso machine with steam wands that are not sealed could allow bacteria to grow in the milk frothing process. Consider the type of beverage you will serve and the number of cups per hour of your space can hold when selecting a commercial coffee maker. It is also important to choose an espresso machine that has automated features, which makes it easier and faster to serve your customers your favorite coffee drinks. Also, look for a warranty that includes parts and labor so that any technical issues are addressed quickly and effectively. Energy Efficiency Commercial espresso machines require significantly more power than the home models. Professional espresso machines weigh more and have larger boilers in order to support multiple group heads in regular cafe production. These machines also operate at a much greater temperature at ambient temperatures and are typically in an indoor space (such as a restaurant or coffee shop) where the electronics may overheat quickly, resulting in malfunctioning machines. The boiler of an espresso machine designed for commercial use heats and holds water which has been pressurized using an electric pump. This water is used to make steam and brew espresso. The boiler is made up of multiple copper tubes heated by electric elements. When the brew level sensor senses that the water has reached its desired level the solenoid valve will open to let the boiler fill with water that is fresh and the heating element shuts off. There are four kinds of espresso machines that are distinguished by how they are able to steam and brew with steam: The TB (brewing only), TX (twin boilers), HX, and DA (double automatic). TB and TX machines offer stable brew temperatures, whereas DA allows for rapid steaming using a single boiler. Many cafes are converting 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 as do cars. They must be maintained in order to run smoothly and efficiently. If you ensure that you keep your machine in good condition, it will provide you a better tasting espresso and last longer. Cleaning your espresso machine is a regular ritual, but it's important to also clean some parts on a deeper level. There's bound to be leftovers from milk and coffee grounds products in the machine that can cause the breakdown of various components over time. Regular cleaning helps prevent this from happening and helps keep your espresso machine running its best. The majority of espresso machines in commercial use require descaling every three months. This process requires additional steps than regular cleaning, so you'll want to go through your manual to ensure that you're adhering to the instructions. Descaling is the process of using a solution that dissolves scale in the water tank. To complete this task you'll need a container underneath the steam wand, and in some units, under the coffee spouts. Follow the directions for your specific model. Another important maintenance step is to change the water filters. It's easy to forget but it's vital not to build up mineral deposits. Check for calcification, which can be difficult to remove in the spray head.
