Abstract
A rotary joint to be used in the irrigation of a wine cap layer within a fermentation tank during a fermenting process. The rotary joint has two sets of ball bearings. The dual sets of ball bearings grants greater support, stability, and mobility to a cantilevered arm that is attached to an end of the rotary joint. The rotary joint includes a first section having a first raceway, a second section having a second raceway, and third section having a third raceway. The first set of ball bearings is positioned on the second raceway and between the first and second raceways. The second set of ball bearings is positioned on the third raceway and between the second and third raceways. The second section is positioned within the third section. The first and third section are secured together with the second section positioned therebetween. A supply line is connected to the first section for providing wine to the rotary joint and a single cantilevered arm is connected to said second section for receiving the wine and dispersing the wine within the fermenting tank.
