A foamed product dispensing system, wherein the system includes: a product dispensing machine (B), configured to receive an exchangeable product container (H); a product container (H), configured to cooperate with the product dispensing machine (B), after placement in the machine (B); wherein the product container (H) contains a foamable product (P), preferably a food product, for example cream, wherein the product container (H) has a product processing unit (PPU) including at least one frothing device (15) having a product entrance (15i) for receiving product (P) and a product exit (15u) for discharging product (P), wherein the processing unit (PPU) is connectable to a gas supply for supplying gas to the product (P), wherein the product processing unit (PPU) comprises a processing device (7) arranged downstream of the frothing device (15) and configured for performing a mixing treatment and/or pressure reduction treatment of the product provided with gas.

The present invention is in the field of stirring, and particularly relates to a stirring assembly including a rotary shaft and a stirring member. The stirring member is fixedly provided on the rotary shaft. The rotary shaft is provided with a first passage therein. The first passage is formed with an air inlet through one end of the rotary shaft. The stirring member is provided with a second passage therein. The second passage is formed with an air outlet through the stirring member. The second passage is connected with the first passage. In the present invention, when the rotary shaft is rotating, the external air is drawn in from the air inlet and discharged from the air outlet to make the liquid to be mixed by the stirring member with the air discharged from the air outlet.
