US Patent 10017722 Fermentation cooling system

A fermentation system having a vessel defining a chamber for holding liquids and including a lower aperture. An insulating jacket is disposed around the vessel. A cooling fluid is disposed between the insulating jacket and the vessel. The cooling fluid is in fluid communication with a fluid pump. A refrigerant line is wrapped around the vessel and is configured to cool the fluid and the vessel, resulting in cooling of liquids disposed in the chamber. A beverage line operably couples the lower aperture with a dispensing spigot. The beverage line is wrapped around the vessel and is at least partially submerged in the fluid. A sediment drain line is disposed below the lower aperture and configured to drain sediment that accumulates on a bottom of the vessel.
