Can PLC automation craft the perfect latte?

20 March 2018

Ubermorgen Innovations says Unitronics is the Cream of the Crop. This German manufacturer offers products for the food and beverage industry. They strive to bring creative engineering solutions to improve reliability and efficiency for their customers. One of their products is Übermilk, a machine that foams milk for cappuccinos and other coffee drinks. 

Übermilk makes life easier for professional caterers and busy baristas; it can create 200 servings of perfectly foamed milk in an hour, or about one portion every 20 seconds. By automating this process, Übermorgen made crafting the perfect cappuccino more efficient and freed up food service professionals to work on other tasks.

Übermorgen also implemented semi-automated cleaning cycles, making Übermilk to be a more hygienic, low maintenance solution. Übermorgen Innovations needed a cost-effective controller to run Übermilk and an attractive, touchscreen HMI for easy operator interface. They selected the Samba all-in-one PLC from Unitronics. The model they selected, SM43-J-TA22, offered a single, compact unit with a full-function PLC, 4.3-inch touchscreen, and onboard I/O including temperature inputs. Using this PLC, a barista can create perfect milk foam with a single button push. The controller measures the correct amount of milk and warms it gently to maintain the optimal flavor and texture of the milk.

The Samba 4.3 PLC+HMI ensure a perfect latte every time, without fluctuations in quality or quantity. Moreover, the Samba offers a very good look and feel, complementing the sleek, professional appearance of the overall Übermilk machine. The customer adds that there was “very good support from the distributor and the manufacturer … good support located nearby us is very important to us.”
