A seal assembly including at least one conduit configured to allow a medium to flow therethrough, an annular retaining means operably coupled to the conduit, and an annular resilient seal member disposed in the annular retaining means. A method of sealing a dispensing system containing a food product creating a food product pressure, wherein the dispensing systems includes a drive shaft operably coupled to a seal assembly, the seal assembly including an annular resilient seal member disposed in an annular retaining member, the annular retaining member being operably coupled to at least one conduit, the method including the steps of: dispensing a medium through the at least one conduit to enter the annular resilient seal member to create a seal pressure greater than or equal to the food product pressure.

1. A seal assembly comprising: at least one conduit configured to allow a medium to flow therethrough; andan annular retaining member operably coupled to the conduit;an annular resilient seal member disposed in the annular retaining member, the resilient seal member comprising a unified u-cup seal including a seal outer perimeter, a seal inner perimeter, and a seal central reservoir space formed between the seal outer perimeter and the seal inner perimeter, wherein the seal central reservoir space is constructed and arranged to be filled by a fluid to pressurize the resilient seal member. 2. The seal assembly of claim 1, wherein the annular retaining member includes a front surface, a rear surface, and at least one retaining means aperture penetrating the front surface and the rear surface. 3. The seal assembly of claim 2, wherein the rear surface comprises at least one resilient ridge to form at least one retaining member cavity therein. 4. The seal assembly of claim 3, wherein the at least one conduit engages the at least one retaining member aperture on the front surface. 5. The seal assembly of claim 1, wherein at least one seal aperture is disposed through the seal outer perimeter into the seal central reservoir space. 6. The seal assembly of claim 5, wherein the resilient seal member is disposed in one of the at least one retaining member cavities. 7. A dispensing system for food and beverage products comprising: a drive shaft, including a rotatable outer surface; anda sealing assembly configured to engage the drive shaft outer surface;wherein the seal assembly comprises: at least one conduit configured to allow a medium to flow therethrough;an annular retaining member operably coupled to the at least one conduit; andan annular resilient seal member disposed in the annular retaining member, the resilient seal member comprising a unified u-cup seal including a seal outer perimeter, a seal inner perimeter, and a seal central reservoir space formed between the seal outer perimeter and the seal inner perimeter, wherein the seal central reservoir space is constructed and arranged to be filled by a fluid to pressurize the resilient seal member. 8. The dispensing system of claim 7 further comprising: a housing;a dispensing mechanism operably coupled to the housing;a stirring mechanism disposed within the housing, wherein the stirring mechanism is operably coupled to the drive shaft; anda motor operably coupled to the drive shaft for rotating the stirring mechanism. 9. The dispensing system of claim 8, wherein the housing is refrigerated. 10. The dispensing system of claim 8, wherein the annular retaining member is configured to engage the housing. 11. The dispensing system of claim 10, wherein the annular retaining member includes a front surface, a rear surface, and at least one retaining member aperture penetrating the front surface through the rear surface. 12. The dispensing system of claim 11, wherein the rear surface comprises at least one resilient ridge to form at least one retaining member cavity therein. 13. The dispensing system of claim 12, wherein the at least one conduit engages the at least one retaining member aperture on the front surface. 14. The dispenser claim 7, wherein at least one seal aperture is disposed through the seal outer perimeter into the seal central reservoir space. 15. The dispenser claim 14, wherein the resilient seal member is disposed in one of the at least one retaining member cavities. 16. The dispenser of claim 15, wherein seal inner perimeter is in contact with the rotatable drive shaft outer surface.
