Mobile beer-dispensing system

A mobile chilled beverage-dispensing system, comprising:

• a wheeled cart including a frame supported by at least two swivel casters mounted to a portion of the frame;
• a fluid storage tank comprising a substantially cylindrical body running from a first end to a second end, the fluid storage tank fastened to the frame and disposed within a guard portion of the frame;
• a fluid dispensing tap connected to the cart;
• a fluid distribution line having a first connection end fluidly interconnected with the fluid storage tank and a second connection end fluidly interconnected with the fluid dispensing tap;
• and
• a cooling system comprising:
• a cooling unit including a refrigeration unit, a refrigerant, and a refrigerant pump;
• and
• a cooling line that is separate from the fluid distribution line, the cooling line interconnected with the cooling unit and configured to convey the refrigerant across portions of the fluid storage tank and the fluid distribution line in a flow direction of a continuous coolant loop, wherein the continuous coolant loop follows a path between a connection of the cooling line to a first port of the cooling unit at a first line end of the cooling line and a connection of the cooling line to a second port of the cooling unit at a second line end of the cooling line, wherein the cooling line in the continuous coolant loop wraps around a end and, after following the length of the fluid storage tank, runs from the first end of the fluid storage tank back along a portion of the length of the fluid storage tank in a direction toward the second end of the fluid storage tank to a point adjacent the first connection end of the fluid distribution line and continues to run along the fluid distribution line from the first connection end to the second connection end.

A mobile beer-dispensing system, comprising:

• a cart comprising a frame supported by two or more wheels attached to a base, of the frame;
• a fluid storage tank mechanically fastened to the frame of the cart and containing a flexible bladder having a fluid, the flexible bladder disposed entirely within a substantially cylindrical body of the fluid storage tank;
• a fluid dispensing tap connected to a portion of the cart;
• a fluid distribution line having a first end fluidly interconnected with the fluid storage tank and a second end fluidly interconnected with the fluid dispensing tap;
• a cooling system comprising:
• a cooling unit including a refrigeration unit, a refrigerant, and a refrigerant pump;
• and
• a cooling line interconnected with the cooling unit and configured to direct the refrigerant along a continuous coolant loop running from a first port of the cooling unit to a second port of the cooling unit, the continuous coolant loop comprising a first portion of the cooling line disposed along a length of the fluid distribution line and a second portion of the cooling line wrapped around a periphery and following along a length of the fluid storage tank, wherein the first portion of the cooling line runs from a point adjacent the first end of the fluid distribution line to a point adjacent the second end of the fluid distribution line;
• and
• a tank pressurization system disposed at least partially within a portion of the frame, the tank pressurization system comprising:
• a compressor;
• a compressed-gas storage tank fluidly connected to the compressor;
• a solenoid valve fluidly connected to compressed-gas storage tank;
• and
• a pressure regulator that controls a pressure of a gas flowing from the compressed-gas storage tank as the gas flows through the pressure regulator, wherein the pressure regulator is fluidly connected to the solenoid valve;
• wherein the tank pressurization system is configured to selectively pressurize the fluid storage tank and compress the flexible bladder having the fluid via the gas flowing from the compressed-gas storage tank through the pressure regulator.
