What to Look For in a Commercial Espresso Machine When you purchase a commercial espresso machine, there are several aspects to take into consideration. The volume of your cafe's operation, service use and barista knowledge will determine which type of espresso machine is best for your business. Double boilers provide the ability to brew as well as steam simultaneously. It also reduces the time 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 a home espresso machine . If you expect a home espresso maker to perform in a professional environment would be an invitation to disaster. A commercial machine of top quality will be able to serve up to 100 cups of coffee per hour at peak times. This is an enormous benefit for busy workplaces, keeping employees from having to wait around while waiting to get their coffee. A coffee machine can also help workers connect. Teams of employees often make a habit of sharing coffee with one another, which could promote collaboration and teamwork in the workplace. The presence of a space specifically for coffee can also aid new employees in feeling at peace in the workplace, removing any barriers between them and the senior employees. Commercial espresso machines are available in various sizes to meet a variety of needs. Some models are completely automatic, while others allow you to prepare espresso shots beforehand so that operators don't have to guess the correct shot size. This is especially crucial for businesses with inexperienced baristas since incorrect shots can greatly affect the flavor and intensity of espresso that is brewed. It is also best to buy commercial espresso machines made from ethically sourced products that benefit the communities where 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 are massive heavy pieces of equipment that can cost as much as a new compact car. The machines are designed to create hundreds of drinks and shots in a single day. Commercial espresso machines could pose unique health and safety risks for employees due to their large volume. It's important to keep in mind that commercial espresso machines are likely to be operating with warm water, which can contribute to the development of bacteria. A machine that isn't maintained properly and hasn't been cleaned or descaled regularly can start to build up spent espresso, which can turn rancid and could potentially cause illness if consumed by customers. A commercial espresso machine that has steam wands that don't have an effective seal can also allow for bacterial growth within the milk frothing process, since it might not be able to attain temperatures sufficient to kill all bacteria. Consider the type of beverage you'll serve and the number of cups an hour can be served when selecting a commercial-grade coffee machine. You should also look for machines that have automation features that make it easier and faster to serve your customers your favorite coffee drink. Make sure you get a warranty that includes both parts and labor. This will ensure that any technical problems will be solved quickly. Energy Efficiency Commercial espresso machines require substantially more power than the home models. Professional espresso machines are heavier and come with larger boilers that can support multiple group heads in regular cafe production. They also operate at a greater temperature at ambient temperatures and are typically located in indoor locations (such as a restaurant or coffee shop) where the electronics may overheat quickly, resulting in machine failure. The boiler of an espresso machine designed for commercial use heats and holds water that has been pressurized with an electric pump. The water is used to brew and steam espresso. The boiler is comprised of several copper tubes that are heated by electric elements. If the brew sensor detects that the water level has reached the target level the solenoid valve is opened and fills the boiler with fresh water. The heating element is then shut off. There are four variants of espresso machines that are distinguished by their capacity to steam and brew the water: TB (brewing only), TX (twin boilers) HX, DA (double automatic). TB and TX machines provide stable brewing temperatures, while DA offers rapid steaming from a single boiler. Many cafes are converting to HX machines since they have been proven to offer the best of both worlds, in terms of steam temperature and brew temperature. Maintenance Similar to how cars require routine tune-ups, commercial espresso machines require maintenance to continue working smoothly and efficiently. If you make the effort to keep your machine in good condition, it will provide you a better tasting coffee and last longer. It's an everyday ritual to clean your espresso machine, however it is important to pay attention to those parts that require an extra clean. There will be a residue of coffee grounds and milk products in the machine which could disintegrate various components over time. Regular cleaning will keep your espresso machine in tip-top condition. The majority of commercial espresso machines require descaling every three months. This is a process that requires additional steps than normal cleaning, so be sure to read the manual to ensure you're following the instructions. Descaling is the process of using a solution that dissolves scale in the water tank. In order to complete this process you'll need a container underneath the steam wand or, in certain models, under the coffee spouts. Follow the instructions for your specific model. Another aspect of maintenance is changing the water filters. This is a step that can be easily forgotten but is essential to keep in mind so you don't end up with a build-up of mineral deposits. You'll also want to check for calcification in the spray head, which can be difficult to eliminate.
