Foamed product dispensing system, product container, and product dispensing machine

A foamed product dispensing system, wherein the system comprises:

• (a) a product dispensing machine, configured to receive an exchangeable product container;
• (b) a product container configured to contain a foamable product and to cooperate with the product dispensing machine, after placement in the machine,
• wherein the product container is provided with a product processing unit (CPU) comprising a frothing device having a product entrance for receiving product and a product exit for discharging product, wherein the CPU is connectable to a gas supply for supplying gas to the product,
• wherein the CPU comprises a processing device arranged downstream of the frothing device and is configured for performing a mixing treatment and/or pressure reduction treatment of the product provided with gas, wherein the processing device comprises an undulating fluid path for the product provided with gas, wherein the undulating fluid path alternatingly comprises first and second path sections, wherein the first path sections are substantially straight and extend substantially parallel to each other, wherein the second path sections each extend at an angle to a direction in which the first path sections extend, the angle being in the range of 45 to 135 degrees, wherein:
• the undulating fluid path has a length of at least 30 cm;
• and/or
• the undulating fluid path has a substantially uniform transversal representative width in the range of 2.8 to 3.2 mm;
• and/or
• the first path sections have a total length that is at least two times larger than the total length of the second path sections.
