The coffee units are one of the crucial elements in beverage vending machines: as they are made of plastic material, it is essential to carry out an initial run-in of the subgroup to then verify the functional parameters, that is, the motor absorption and check of the hydraulic circuit seal. The testing sequence therefore provides for an initial product run-in by simulating a series of product dispensation in sequence with the liquid at the temperature expected during use.

The tests conducted in the Coffee Machine Units Testing Bench are:

• Electric absorption checking on specific points of the system in rotation
• Seal under pressure checking of a hydraulic circuit

All the stages can be customised with a configurable “testing recipe”. The information collected is made available to the company Information Systems in order to guarantee testing data traceability for every tested product (as they are marked with a unique serial number).
