Draught Beer Dispensers

Soft Drink Dispensers
To Carbonate To Dispense
At every single one of these
retailers you will find a
Dispensing System with one
vital piece of Equipment…
The CO2 Gas Cylinder
Since 1902, the CO2 gas cylinder has remained virtually the same…
“…Harrisburg Steel Corporation (Harrisburg Pipe)
installed two new furnaces and used the plate process to produce America’s first seamless gas cylinders in 1902…”
* Published June 14. 2005, “A Brief History of Gas Cylinders”, Compressed Gas Manufacturers Association
In 1904, the gas cylinder really took off…
…”Two years later, a prominently placed carbon dioxide cylinder would further advance the cylinder business, when the Anheuser-Busch Brewery displayed a carbon dioxide cylinder from Harrisburg Steel Corporation to pump draft beer at the 1904 World’s Fair in St. Louis. Beer on tap became so popular that many saloons were renamed taprooms—giving carbon dioxide cylinders a starring role in watering holes across the nation.” *

Carbon Dioxide gas
is a by product of
many petrochemical
industries
Where it is captured,
cleaned and liquefied
Liquefied CO2 is
transported to
Industrial Gas
Suppliers
Bottles are
professionally filled
at site centric plants
Transporting CO2
cylinders need to
comply with USDOT
Regulations
Draught Beer has Cooling needs and issues
that Soft Drink dispensing does not
have…
In the Draught Beer
industry, a constant
challenge centers on
temperature issues and the
time, energy and effort
needed to serve a Draught
Beer at 38*F (optimal)
“Our mission is to
create innovative
solutions to enhance
the Draught Beer
Experience for the beer
lover – brewer,
distributor and retailer
by ensuring optimal
preservation and
dispensing of the
finest form of Beer –
Draught Beer.”
The higher the beer temperature - the higher the CO2 pressure needed to dispense.
The higher the CO2 pressure - the higher the foaming.
The higher the foaming - the higher amount of wasted beer.
Carbonation Scale
World Cup 2006
It was estimated that nearly 40% of all Draught Beer could not be dispensed at Stadium Concession Stands and Outdoor Venues due to the hot weather in Germany at the month long FIFA World Cup tournament
What should have been this…
May have led to this…(kidding)
How Dry Ice can change the way Carbonated Beverages are Cooled,
Carbonated and Dispensed…
Dry Ice is Solid Carbon
Dioxide
It Sublimates (changes)
into CO2 Gas
Extremely Cold (-109*F)
How is Dry Ice
made?
Dry Ice is almost 5x
colder than Wet Ice
Where Can I Get Dry
Ice?
› Over 4,500* Retail
Locations including
Grocery Stores, Big
Box Retailers and
Specialty Stores
* According to Airgas, the largest Dry Ice
seller in the US
How Much does Dry
Ice Cost?
› Around $1.00 –
$1.50 per pound
(retail)
More Energy Efficient
Dry Ice can lessen the heavy load needed to Cool carbonated
beverages dispensed from kegs
More Cost Efficient
Dry Ice can lower the amount of Draught Beer foaming (waste)
Dry Ice can lessen the time and energy needed to Cool
More Availability
Dry Ice can open up new areas of service for Draught Beer
More Enviro - Friendly
Dry Ice could lessen the heavy Carbon Footprint for Beer
More Energy Efficient
Dry Ice can lessen the heavy load needed to Cool carbonated beverages dispensed from
kegs *
* By lowering the amount of electric energy required for artificial refrigeration directly
to Cool or to create Wet Ice for contact cooling.
More Cost Efficient
Dry Ice can lower the amount of draught
beer foaming (waste) *
* By improving Cooling efficiencies, Dry Ice
can lessen the amount of CO2 pressure
needed as well as lowering energy bills
More Availability
Dry Ice can open up new areas of service
for Draught Beer *
* Draught Beer service is currently limited
by a number of factors aligned with
Cooling and CO2 pressure issues
More Enviro – Friendly
Dry Ice systems could lessen the heavy
Carbon Footprint for Beer
* By lowering the time and electric energy
currently required for optimal cooling
Option 1: Cooling the
Keg
1. Artificial Refrigeration:
Kegerators or Walk-In
Refrigerators
2. Ice Bath
Option 2: Cooling the
Beer lines
1. Jockey Box System
2. Flash Chiller
Artificial Refrigeration
1. Keg Refrigerators or Kegerators can be found in retail locations as well as individual homes (Man Caves)
2. Walk In Refrigerators
Wet Ice
1. Kegs are placed in
wet ice baths
2. Ice bags are placed
on top of Keg
Jockey Box System
1. Insulated container filled with wet ice & water
2. Keg and CO2 tank standing at room temperature
3. Beer is run through lines that are submerged in ice bath
Flash Chillers – Ice Bank
1. Keg and CO2 tank at ambient temperature
2. Beer is pushed through beer lines located in an ice bath
3. Flash Chiller/Ice Bank Unit is similar to an ice making machine as it creates an ice bath inside the machine
In 2006, while creating a new Kegerator, we first researched using Dry Ice to quickly Cool the Keg
It is estimated that it takes 12-24 hours to cool a keg from 48*F to 38*F in a Kegerator – Walk In Refer
We also tried to create a Kegerator where the CO2 cylinder wouldn’t sit outside
Cooling Ring Solutions – Dry Ice using Pressure Vessels that are placed on top of Kegs for Contact Cooling
Cooling Canisters Solutions – Dry Ice using Pressure Vessels that are placed inside Jockey Box and some Flash Chiller Systems
Cooling Bags & Boxes Solutions – Dry Ice using Pressure Vessels that are placed inside some Jockey Box and some Flash Chiller Systems
We created the first of many different Pressure Vessels using Dry Ice
Toroidal Shaped High Pressure Vessel that when placed on top of a Keg, creates intense contact cooling
Captures sublimating CO2 gas
The Cooling Ring
We have created several Pressure Vessels that can be used in Jockey Box and Flash Chiller Systems
These are placed inside the Ice Baths to preserve the Cooling and greatly lessen the amount of wet ice needed
Eliminates the standard CO2 cylinder
The Cooling Canister
The Cooling Bags & Boxes
These Pressure Vessels are used specifically for use in Ice Bank Units and Jockey Box systems
They fit in “tight” spaces
The Cooling Box allows for easy insertion of up to 11 lb block of Dry Ice
Dry Ice Solutions
“Keg-U-Later has created solutions to
capture the Cooling and Sublimation
powers of Dry Ice for an alternative way
to Cool, Carbonate and Dispense
carbonated beverages…”
