FIELD: food industry. SUBSTANCE: saturator 14 has external rigid container 15. Inside the container there is vessel 16. The vessel shrinks and swells. As the cycle begins, vessel 16 is squeezed by spring 22. Water enters vessel 16 through tube 18, and the vessel swells until pressure of the spring balances pressure in the tube. Valve 20 cuts off the inflow of water, and carbon dioxide is forced through pipeline 25 and diffuser 24. EFFECT: higher efficiency. 2 cl, 7 dwg
