What to Look For in a Commercial Espresso Machine There are many things to consider when purchasing commercial espresso machines. The kind of espresso machine appropriate for your cafe will depend on the amount of use, the purpose, and barista skills. Double boilers allow you to brew while steaming. This can reduce the time needed to recuperate 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 larger amount of coffee than an espresso machine at home. Expecting a domestic espresso machine to work in a professional setting would be an unintentional recipe for disaster. A commercial machine that is of high quality can serve up to 100 coffee cups in an hour during peak times. This can be a lifesaver for busy workplaces by preventing employees from having to wait for a long time to get their coffee. The presence of a coffee maker in the workplace can help workers to bond with each other. Oftentimes teams of people will make a habit of getting coffee for each other, and this can foster teamwork and collaboration in the workplace. Having a dedicated space to enjoy coffee can help new workers to feel at comfortable in the workplace, and break down any barriers between them and senior employees. Commercial espresso machines are available in various sizes to suit a variety of needs. Some models are entirely automated while others are able to pre-program espresso shots, so that the operator does not have to guess at the correct size of the shot. This is especially important for businesses that have baristas that aren't properly trained, as inaccurate shots can affect the intensity and taste of espresso. It is also best to buy commercial espresso machines that are made of ethically sourced materials that help the communities where coffee beans are harvested. This will ensure a high quality product and minimize the negative impact on the environment. Safety Espresso machines are big heavy pieces of equipment that can cost more than a brand new compact car. They're also designed to churn out hundreds of drinks and shots throughout the course of one day. Commercial espresso machines can pose particular health and safety hazards to staff due to their large volume. Keep in machine espresso that commercial espresso machines are likely to make use of warm water. This could encourage the growth of bacteria. If a machine is not properly maintained and hasn't been cleaned or descaled regularly can start to build up spent espresso, which can turn rancid and could potentially cause illnesses if consumed by consumers. Commercial espresso machines with a steam wand that is not sealed could allow bacteria to flourish in the milk foaming process. When deciding on an espresso machine for commercial use, it's important to consider the kind of drinks you plan on serving and the number of cups per hour your space will be able to handle. You'll want to choose machines with automated features that will make it simpler to serve your customers the best coffee beverage. Look for a warranty which includes both labor and parts. This will guarantee that any technical issues can be addressed quickly. Energy Efficiency The power requirements for commercial espresso machines are considerably more powerful than those used in home settings. Professional espresso machines are more heavy and come with larger boilers in order to support several group heads for standard cafe production. These machines operate at higher temperatures, and are usually located in indoor areas (such as in a coffee shop or restaurant) where the electronics could overheat. The boiler of an espresso machine designed for commercial use heats and stores water which has been pressurized using an electric pump. The water is then used for brewing and steaming espresso. The boiler is made up of several copper tubes that are heated by electric elements. When the brew sensor detects that the water level has reached its target level the solenoid valve will open and fills the boiler with fresh water. The heating element is then turned off. There are four variants of espresso machines that are distinguished by how they are able to steam and brew in the form of TB (brewing only), TX (twin boilers) HX, TB, and DA (double automatic). TB and TX machines ensure stable brew temperatures, while DA can provide rapid steaming using a single boiler. Many cafes are switching to HX machines as they have been shown to offer 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 to operate efficiently and smoothly. If you ensure that you maintain your machine in good condition, it will give you a better tasting coffee and last longer. It's a routine to clean your espresso machine, but it is important to pay attention to those parts that require an extra clean. There's likely to be residue from coffee grounds and milk products in the machine that could break down various components over time. Regular cleaning can prevent this from happening and helps keep your espresso machine running to its maximum. Most commercial espresso machines need descaling every three months. This is a process that requires a few more steps over regular cleaning, so it's best to review your manual to ensure you're following the directions. The solution used to descal the water tank dissolves the scale. In order to complete this process you'll need to place a container underneath the steam wand or, in some units, under the coffee spouts. Follow the instructions for your specific model. A water filter change is an additional maintenance task. This is a step that can easily be forgotten, but it's important to keep in mind so you don't build up of mineral deposits. It is also important to look for calcification in the spray head, which is difficult to eliminate.
