What are your

goals?

Package an existing

Create a nitro variation

of an existing beer?

Design a new nitro

beer?

Make something

How much CO2 Do I Need?

1.2-1.8 Vol CO2


3 Methods of Nitrogenating Beer For Cans

7

In-Tank Nitrogenation

High pressure rated brites and PRVs

Push GN2 through carb stone, monitor head space pressure at 45psi

Counter-pressure fill, dose, seam, and sell

In-Line Nitrogenation

Must have gassing panel or in-line membrane infusion device

Infuse GN2 or beer gas (75% N2, 25% CO2) through gassing panel from brite tank to filler

Counter-pressure fill, dose, seam and sell

In-Can Nitrogenation

Package low carb beer from brite within 1.2-1.8 vol range

Fill at low pressure, dose, seam, and store cold for 5 days before selling

Easiest method


Nitrogen Solubility

8

Pressure

25-45psi in can

Temperature

40F or colder

Time

5 days stored cold

Low solubility in liquid

Requires 3 environmental conditions for beer

Time can be accelerated by increasing surface area of the beer exposed to nitrogen


Agitation

You can fast forward the time it takes for nitrogen to dissolve into solution by increasing amount of liquid exposed to the nitrogen molecules in the headspace over a short period of time

By shaking a can of pressurized beer dosed with LN2 for two minutes, you can achieve the same solubility state as 5 days cold


A Warning About

Refermentation

Can pressure ratings may vary from manufacturer and seam quality

Dosing can increase interior can pressures to 45 psi, leaving less room for pressure build up

Unfiltered, non-pasteurized beers with residual sugars are most susceptible


Widget Technology

11

First patented by Guinness in 1972

First commercial product released

in 1989

Floating widget released in 1997

Fixed Widget Released by Ball

Corp in 2010


Fixed widgets serve as nitrogen

storage containers inside the can

Two one-way valves

Pressurized to equilibrium

After opening, the pressure

differential causes the gas to escape

and agitate the solution

Drink from the can or pour into a

glass


Important to maintain fill level and headspace

consistency

Three purge cycles recommended at 60 psi

Cans must be immediately inverted to allow LN2 boil-

off to occur at widget valve

Can pressures must be tested from lid, not from

bottom

LN2 DoseVaporized N2


The Hard Pour

Inexpensive and easy

alternative to the widget

Exactly the same cascade /

nitro effect

Must have means of achieving

cold infusion if not pre-

nitrogenating

Requires consumer education

Best consumed from a glass


Dissecting a

Nitro Head

The cascade effect is

caused by a combination

of protein hydrophobicity

and super small nitrogen

bubbles

The head has two parts:

smaller, compact bubbles

on the bottom and larger,

airier bubbles on top



The Right Glass Does Matter

17

Don’t stop the consumer education at how to pour…

Keep Cold, Drink Fresh, Pour Hard, and Use the right Glass!

Flat Bottom

No tulips

2-5 degree slope

Taper toward the rim

Slope changes will cause the cascade to

clump together


So You Want to

Can Nitro Coffee?


Nitro Coffee – Another Hot Market

But Let’s Talk Safety…19© 2020 Chart Industries, Inc. Confidential and Proprietary

Clostridium

Botulinum (CBot) Toxin-producing bacterium

found in nature and present on all food surfaces

Requires anaerobic conditions to sporulate and create toxins

Requires heat to kill or cold chain to prevent

Risky in foods with pH of 4.6 and above

Managing TPO will not prevent growth


Filling

Use existing filler for

beer

Tank, In-Line, or In-Can

nitrogenation

No CO2 break out to

worry about

Make sure you dose with

liquid nitrogen


Nitro RTDs

Similar to hard seltzer, create neutral base from malt and design cocktails

Carbonated cocktails are most popular

Widget cans being used for aerated cocktails

Opportunity for “shake-and-pour” widget-less cans


Canned Wine

Attract new market

Easy to transport and drink outdoors

Drink from the can or pour into a glass

Improved Shelf Stability for Natural Wine

Opportunity for Nitro wine-based cocktails

What Else Can I

Make?

Coffee Beans

Bags and Cans

Package fresh or de-gassed

Ground Coffee

Cannabis

Loose in cans

Pouches

Extracts

Added to beer

Principles of

Liquid Nitrogen

Dosing


Safety First!

28

Nitrogen is an inert gas

Tasteless, odorless, colorless

Asphyxiant

Liquid Nitrogen exists at -180°C (-320.4°F)

Will cause burns on skin with prolonged exposure

Good NewsNitrogen will not affect the taste or freeze your beer

Chart Dosers are not pressure vessels

Open to atmosphere and automatically vents


Nitrogen is the most Common Gas

Found in the Air…

29

…but it can only exist as a liquid at

temperatures below -320F

Nitrogen78%

Oxygen20.9%

Argon.9%

CO2 and Other Gases.2%

How We Dose

Filler Heads

Doser Head


Typical Tank

Installation

Bulk LN2 Tank (Low

Pressure)

Fixed Pipe Installation

Isolation Valves

Phase Separator

Chart Doser

Stand/Base/Mount


Doser Integration Integrated within a

filler enclosure

Standalone Controller or full HMI integration

Encoder capable for accuracy at high speeds

It's important for Chartto be involved as soon as the manufacturer is known


Liquid

Nitrogen

Consumption

Example

35

40 BBLs into 16oz Cans

35 cans per minute

.25g Liquid Nitrogen per Dose

40 BBLs = 9920 Cans (assuming no loss)

9920 x .25g = 2480g or 2.5L of LN2 (less than 1 gal)


Application Example


Liquid Nitrogen

Expansion

Expands rapidly from a liquid to a gas

1 : 694 volumetric expansion

.5g dose equates to 430ml after accounting for density

Visual “fog” characteristic of cold water vapor is being pushed out of the head space as the nitrogen expands


CryoDoser Flex

Craft Custom

Specifically designed for the craft beverage industry

Compact and easy to operate

Works easily with most fillers

Dynamic Dose Duration for In-Line Fillers

Integrated Purge

Grow from introductory canning line to 750cpm

Removable arm for custom heads
