Abstract

A fermentation system includes a vessel defining a chamber for holding liquids and including a lower aperture, an insulating jacket disposed around the vessel, and a cooling fluid disposed between the insulating jacket and the vessel, the cooling fluid being in fluid communication with a fluid pump. A beverage line operably couples the lower aperture with a dispensing spigot, the beverage line being wrapped around the vessel and at least partially submerged in the fluid. The system further includes a collar disposed proximate the conical bottom portion of the vessel, the collar including a gasket in abutting contact with the insulating jacket.

First claim

What is claimed is:

1. A fermentation system comprising:
a vessel defining a chamber for holding liquids and including a neck extending to a lower aperture;
an insulating jacket disposed around the vessel and defining an opening, the neck of the vessel extending through the opening;
a cooling fluid disposed between and in contact with both the insulating jacket and the vessel, the cooling fluid being in fluid communication with a fluid pump;
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; and
a collar coupled with the neck of the vessel, the collar including a gasket in abutting contact with the insulating jacket to maintain the cooling fluid within a space between the insulating jacket and the vessel.

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, the neck extending from the 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 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 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 the neck of the vessel; and
a sediment drain line disposed below the lower aperture and configured to drain sediment that accumulates on a bottom 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 and in contact with the insulating jacket and the vessel; 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 selectively operably coupled with a tap for dispending liquid from the vessel and decoupled with the tap receiving hot wort for circulation through the beverage line for 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 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 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; 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 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:
an insulating jacket disposed around the vessel;
a fluid disposed between and in contact with both 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 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, the sediment removal assembly being in communication with the sediment collection device.

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 selectively operably coupled with a tap for dispending liquid from the vessel or receiving hot wort for circulation through the beverage line, to cool the wort and introduce the wort into the chamber.

17. The fermentation system of claim 12 , wherein the stopper is slideable within the reservoir under internal pressure from the vessel when the vessel is rotated.

18. The fermentation system of claim 12 , wherein the reservoir is defined in a cylindrical body having a first axis about which the reservoir is rotatable, the reservoir being defined by a cylindrical opening formed through the cylindrical body and extending along a second axis normal to the first axis.

19. The fermentation system of claim 12 , wherein the sediment removal assembly further includes a plunger coupled with the stopper to force sliding of the stopper within the reservoir by a force applied on an end of the plunger opposite the stopper and disposed outside of the reservoir.

20. The fermentation system of claim 12 , further comprising a purge tank removably engageable with the vessel in communication with the reservoir.
