What to Look For in a Commercial Espresso Machine There are a number of aspects to consider when buying an espresso machine for commercial use. Your cafe's volume, intended service use and barista knowledge will determine which type of espresso machine is the best for your business. A double boiler system allows you to brew while steaming. This reduces the time required to recuperate between pulls. Proportional-integral-derivative (PID) temperature control manages on/off cycles for optimal boiler temperatures. Productivity A commercial espresso machine can handle a higher amount of coffee than a home machine. A domestic espresso machine to perform in a professional setting could be an invitation to disaster. A commercial machine of top quality will be able to serve up to 100 coffee cups every hour during peak hours. This can be a great help in busy workplaces, since it keeps workers from waiting to get their coffee. Coffee machines at work can allow workers to connect with each other. In many cases, teams of workers make a habit of getting coffee for each other, and this can encourage collaboration and teamwork in the workplace. The presence of a space specifically for coffee is also a great way to help new workers to feel at ease in the workplace, and break down any barriers between them and senior staff members. Commercial espresso machines are available in various sizes to suit a variety of requirements. Some models are completely automatic and others are able to prepare espresso shots beforehand so that operators don't have to guess the correct size of the shot. This is particularly important for businesses with untrained baristas, since inaccurate shots can drastically affect the flavor and intensity of brewed espresso. It is also best to buy commercial espresso machines that are made of ethically-sourced materials that support the communities in which coffee beans are grown. This will ensure that the product is of good quality and minimizes the negative impact on the environment. Safety Espresso machines can cost as much money as a small car. They are designed to make hundreds of drinks and shots in one day. The high volume of operations result in unique health and safety risks for staff, so it's important to consider the risks that could be associated with the commercial espresso machine. Remember that commercial espresso machines are likely to make use of warm water. This can lead to the growth of bacteria. A machine that is not maintained properly and isn't descaled or cleaned regularly can start to build up spent espresso, which could become rancid and cause illness if consumed by customers. A commercial espresso machine with a steam wand without an effective seal could permit bacterial growth in the milk frothing process, as it might not be able temperatures that are sufficient to kill all bacteria. When choosing a commercial espresso machine it's important to consider the type of beverages you'll be serving and how many cups your space will be able to handle. You should look for a machine with automation features that make it easier to serve your customers the best coffee beverage. In addition, you should look for a warranty that covers parts and labor to ensure that any technical issues are addressed quickly and effectively. Energy Efficiency The power requirements of commercial espresso machines are much higher than home models. This is due to the fact that professional espresso machines are built with heavier frames and large capacity boilers to handle the multiple group heads needed for standard cafe production. These machines operate at a higher temperature and are generally located inside (such as in a cafe or restaurant) where the electronic components may overheat. The boiler of a commercial espresso machine heats and stores pressurized water that is supplied by an electric pump. This water is used to make steam and brew espresso. The boiler is comprised of several copper tubes that are heated by electric elements. When the brew level sensor senses that the water has reached its target level the solenoid valve will open to fill the boiler with fresh water and the heating element is turned off. There are four types of espresso machines, differentiated by how they are able to brew and steam in the form of The TB (brewing only), TX (twin boilers) HX, TB, and DA (double automatic). TB and TX machines have stable brew temperatures, whereas DA can provide rapid steaming using the use of a single boiler. HX machines are in use in many cafes since they offer the best in both steam and brew temperature. Maintenance Commercial espresso machines require regular maintenance as do cars. They must be maintained to work efficiently and smoothly. If you take the time to maintain your machine in good condition, it will give you a better tasting espresso and last longer. Cleaning your espresso machine is a daily ritual, but it's vital to clean your machine at a deeper level. There will be residues from coffee grounds and other milk products that can cause the machine to fail over time. Regular cleaning will keep your espresso machine in good condition. Most commercial espresso machines require descaling every 3 months. This process requires a few extra steps in comparison to regular cleaning. You'll need to go through your manual so that you follow the directions. Descaling involves using a solution to dissolves scale in the water tank. You'll need a container in order to finish this task. In espresso makers there may be a container to be placed under the coffee spouts. Follow the steps for your particular model. A water filter change is an additional maintenance step. This is something that could be easily forgotten but is essential to keep in mind so you don't get a build-up of mineral deposits. Examine for calcification. It can be difficult to remove, in the spray head.
