Abstract

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.

First claim

What is claimed is:

1. A fermentation system comprising:
a vessel defining a chamber for holding liquids and including a lower aperture;
an insulating jacket disposed around the vessel;
a cooling fluid disposed between the insulating jacket and the vessel, the cooling fluid being in fluid communication with a fluid pump; and
a refrigerant line wrapped around the vessel and configured to cool the fluid and the vessel, resulting in cooling of liquids disposed in the chamber;
a beverage line operably coupling the lower aperture with a dispensing spigot, the beverage line being wrapped around the vessel and at least partially submerged in the fluid;
a sediment drain line disposed below the lower aperture and configured to drain sediment that accumulates on a bottom of the vessel; and
a collar disposed proximate the conical bottom portion of the vessel, the collar including a gasket in abutting contact with the insulating jacket.

2. The fermentation system of claim 1 , wherein the cooling fluid includes a glycol solution.

3. The fermentation system of claim 1 , wherein the vessel includes a conical bottom portion.

4. The fermentation system of claim 1 , wherein the insulating jacket includes expanded polystyrene.

5. The fermentation system of claim 1 , further comprising:
a refrigerating unit in fluid communication with the cooling fluid and which cools and circulates the cooling fluid.

6. The fermentation system of claim 1 , further comprising:
a sediment collection device disposed on a bottom portion of the vessel.

7. A fermentation system comprising:
a vessel defining a chamber for holding liquids and including a lower aperture;
an insulating jacket disposed around the vessel;
a fluid disposed between the insulating jacket and the vessel; and
a refrigerant line wrapped around the vessel and configured to cool the fluid and the vessel, resulting in cooling of liquids disposed in the chamber; and
a beverage line operably coupling the lower aperture with a dispensing spigot, the beverage line being wrapped around the vessel and at least partially submerged in the fluid, the dispensing spigot being operably coupled with one of a tap and a hot wort injection unit, wherein the hot wort injection unit is configured to circulate wort through the beverage line, cooling the wort and injecting the wort into the chamber.

8. The fermentation system of claim 7 , wherein the vessel includes an upper flange with a tap extending upwardly therefrom, the tap being operably coupled with the dispensing spigot.

9. The fermentation system of claim 7 , wherein the vessel includes a conical bottom portion.

10. The fermentation system of claim 7 , further comprising:
a refrigerating unit in fluid communication with the cooling fluid and which cools and circulates the cooling fluid.

11. The fermentation system of claim 7 , further comprising:
a sediment collection device disposed on a bottom portion of the vessel.

12. A fermentation system comprising:
a vessel defining a chamber for holding liquids;
an insulating jacket disposed around the vessel;
a fluid disposed between the insulating jacket and the vessel;
a refrigerant line wrapped around the vessel and configured to cool the fluid and the vessel, resulting in cooling of liquids disposed in the chamber; and
a sediment removal assembly disposed on a bottom of the vessel and which includes a rotatable sediment reservoir having a stopper sealingly engaged with a wall of the sediment reservoir and slideable within the reservoir under internal pressure from the vessel to expel excess sediment collected within the vessel when the reservoir is rotated.

13. The fermentation system of claim 12 , wherein the vessel includes an upper flange with a tap extending upwardly therefrom, the tap being operably coupled with the dispensing spigot.

14. The fermentation system of claim 12 , further comprising:
a refrigerating unit in fluid communication with the fluid and which cools and circulates the fluid.

15. The fermentation system of claim 12 , further comprising:
a sediment collection device disposed on a bottom portion of the vessel.

16. The fermentation system of claim 12 , wherein the vessel further defines a lower aperture, the fermentation system further including:
a beverage line operably coupling the lower aperture with a dispensing spigot, the beverage line being wrapped around the vessel and at least partially submerged in the fluid, the dispensing spigot being operably coupled with one of a tap and a hot wort injection unit, wherein the hot wort injection unit is configured to circulate wort through the beverage line, cooling the wort and injecting the wort into the chamber.
