The KB90 allows for more efficient drink production, while reducing strain, and increasing the quality of coffee service.

The KB90 is the ultimate evolution of the Linea PB form. Designed specifically to increase speed of service in the highest volume cafes while easier for the barista thanks to an improved workflow. La Marzocco has redesigned the portafilter system to improve workflow efficiency and to reduce the wrist strain of the user. Efficiency can also be increased thanks to Steam Flush: after each extraction, a burst of steam from the grouphead is followed by a flush of hot water, keeping the machine clean even in the busiest rush hours. This innovative function minimizes off flavored buildup, and increases the time between having to clean the group. The KB90 allows for a new level of expression in machine design, the panels have been engineered so that virtually infinite customization combination can be created.

Straight In Portafilter System

Designed to simplify the motions required to engage the portafilter and reduce the strain by 12 times on the barista for even greater performance and everyday usability. High volume coffee environments demand that a barista can work fast and efficiently to produce drinks during busiest periods of the day. The Straight-In Portafilter can noticeably mitigate the repetitive stress injuries occurring through its ease of action improving the natural workflow and output of barista.

Auto steam flush

After each extraction, a burst of steam from the steam boiler purges the brew path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative function minimizes coffee residue in the group, and reduces the number of times baristas need to back flush during service.

Auto brew ratio with drip prediction

Precision scales incorporated into the drip tray improve beverage consistency by stopping the extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot accuracy and ease of dialing in.
