Embodiment 1

[0111] Example 1 - Process of brewing beer

[0112] figure 1 Embodiments of the disclosed methods are shown. Embodiments of the disclosed system are also shown. In this example, six points in time during the brewing process are shown, namely figure 1 .A-1.F. The process takes a total of 68 hours, from the point of time when the wort enters the fermenter to decanting the fermented wort or beer. figure 1 .A shows wort entering the fermenter and circulating between the first and second side ports, i.e. from the first side port to the second side port, here the regulated pump flow is set to 60 of the full pump flow %. This first point in time is when the process has been running for 7 hours. After 20 hours, the fermenter was completely filled, as figure 1 .B, and the partially fermented wort is circulated through all side ports, in particular exiting from the second and fourth side ports, and returned to the fermenter through the first and third side ports, here at full pum...

Embodiment 3

[0115] Example 3 - Another process for brewing beer

[0116] image 3 An embodiment of the method according to the invention for fermenting wort in a fermenter is shown. Embodiments of the disclosed fermentation system comprising a fermenter and a circulation system are also shown. image 3 .A-3.I show nine time points during beer brewing.

[0117] The process takes a total of 68 hours, which is the point from when the wort enters the fermenter to decanting the fermented wort or beer.

[0118] image 3 .A shows a fermenter according to the invention. The fermenter includes a bottom port and at least three side ports, the at least three side ports being a first side port, a second side port, and a third side port, wherein the side ports are in fluid communication with each other. Additionally, a fourth side port is shown. image 3 .A further shows wort first entering the fermenter through the bottom port. Here the wort can be added with yeast and incubated under conditio...

Abstract

The present disclosure relates to a method for fermenting a wort in a fermentation tank comprising a bottom port and at least three side ports, being a first side port, a second side port, and a thirdside port, wherein said side ports are in fluid communication with each other, comprising the steps of: letting wort into the fermentation tank via the bottom port; pitching wort with yeast; incubating wort with yeast under conditions that allow the yeast to grow, thereby obtaining a partly fermented wort, and pumping the partly fermented wort out of the fermentation tank via at least one of theside ports and back into the fermentation tank via at least another of the side ports.

Description

field of invention [0001] The present invention relates to a fermenter which reduces the time for brewing beer. In particular, the invention relates to fermenters having side ports and methods of operating such tanks. More specifically, the present invention relates to a fluid communication unit connected to a fermenter having side ports. Background of the invention [0002] Beer brewing is a time-consuming process. Generally, about 200 hours or more are required from the time of adding yeast to the wort to the time of decanting fermented draft beer. Therefore, it is highly desirable to provide a method and system for reducing brewing time. [0003] An example of a brewing system is described in DE 100 03 155 in which a fermenter is used and connected to a plurality of external containers. However, such systems are not very efficient, and it is not practical to have several processes take place at different locations. Summary of the invention [0004] A first aspect o...
