In the fast-moving food industry of today, keeping up with the competition is of vital importance.Customers demand better and newer products almost every other day, and they also expect low
prices and high availability. Being able to meet these demands means inventing new food products
and using the best technology for processing them and keeping them fresh, tasty and healthy.
With decades of experience as a food production supplier, we at Linde Gas are able to offer a wide
variety of high-quality, state-of-the-art freezing and cooling equipment for the food industry.
Liquefied gases serve as excellent coolants
Liquid carbon dioxide and nitrogen can be stored at very low temperatures (CO2at -78 C, N2at
-196 C). When these liquids vaporise in contact with warmer materials, they absorb a large amount
of heat from them and turn into very cold gases. These gases can then be used to remove heat
from other materials before being safely released into the atmosphere. This method, known as
cryogenic freezing and cooling, has been in industrial use for over 40 years and is well known for
producing high-quality frozen and chilled goods.

Advanced technology for better products.
Slow freezing can damage food products
When any foodstuff is frozen, there are three steps to this process. First, the temperature is reduced to the
freezing point. The water in the foodstuff then turns into ice (this is also called the latent heat phase). Finally,
the temperature is further reduced to the final freezing point (usually -18 C). Slow freezing, however, candamage food products because the process destroys their cells.
1. Free water surrounding the food cells
is the first to crystallise during slow
freezing methods.
2. As soon as the water balance is de-
stroyed, the water within the food cells
starts to break out of the cells, destroy-
ing the cell walls. The longer the freezing
time the more cells are destroyed.
3. Finally, the ice crystals become so
big that the cells are completely broken
down, leading among other disad-
vantages to a high degree of water
loss when the product is defrosted or
re-heated.
Higher quality through faster freezing
Because of the reasons explained above, the freezing process must be
passed through as quickly as possible in order to reach high product
qualities. By using fast cryogenic freezing, the water inside and outside
of the cells freezes at the same rate, ensuring that the cells remain intact
and the food keeps its freshness, flavour and texture as if it hadnt been
frozen at all.
The organic cell structure remains
virtually unchanged when fast freezingtechnology is applied.

The benefits of freezing and coolingequipment by Linde Gas.
With our innovative equipment, freezing and cooling pro-
cesses can be carried out quickly and efficiently, significantly
increasing the output and making your products highly
available. Moreover, faster refrigeration increases the IQF
food quality (IQF = individually quick-frozen). And this in
turn enables you to develop and lead the market with new,
attractive food products.
When using our machinery, you can also profit from a high
degree of flexibility: different types of freezers are available
for a wide range of food products. And because they usually
have a small footprint, they need only very little space.
Fast freezing means higher production speed Higher product quality than with slow cooling
Products lose less water when defrosted
Lower dehydration, higher yield

CRYOLINEMT tunnel freezer
This is a general-purpose, in-line tunnel freezer and cooler,
combining state-of-the-art electronic controls with a high
level of hygienic design. Adjustable, high-speed internalfans, controllable exhaust levels and gas injection make the
use of cryogenic gases highly efficient. The tunnel has an
attractive, easy-to-clean outer design which covers all the
motors and pipes.
Typical products:
Meat and meat products
Dairy products
Fish and seafood Ready meals and other
convenience foods
Bakery products
CRYOLINE
MCThe CRYOLINEMC is an extension of the CRYOLINEMT
tunnel freezer. It quick-freezes high-value isolated products
using nitrogen at -186 C in order to harden the surfaces of
particularly delicate foodstuffs and to avoid deformation and
agglomeration. After stabilisation, the product is deep frozen
by a belt freezer and can then e.g. be glazed with water or
packaged. The modules are entirely interconnected to ensure
that all the cold gas from the immersion section is used.
Typical products: Delicate free-flowing products
Shrimp
All kinds of berries
Mushrooms
Cut vegetables
CRYOLINECF cabinet freezer
The CRYOLINECF is a multi-purpose freezing and chilling
cabinet designed for batch production facilities such as bak-
eries and ready meal lines. It features a modern touch-panel
control system which offers fine control of all functions,
providing high efficiency as well as ease of use. The unit is
designed for high levels of hygiene, making it easy to clean

CRYOLINESC super contact freezer
For products which are difficult to handle, the CRYOLINESC
in-line tunnel freezer uses a patented, disposable foil belt.
The unit can easily freeze or cool liquid and/or marinatedproducts or harden soft products (e.g. fillets of fish or
chicken) prior to final freezing. Because the belt is dispos-
able, it is possible to change products during the production
cycle without having to clean it. Another advantage over
mesh belts is that the foil is smooth, which is perfect for
processing soft foodstuffs without belt marks.
Typical products:
Fillets of fish
Soft products such as pancakes
Tenderloin steaks Pures
Liquid and semi-liquid products
Pasta products
CRYOLINE
PE pellet freezerThe patented CRYOLINEPE uses a solid, stainless-steel
belt with cavities to form pellets of liquid or semi-liquid
foodstuffs even with solids such as onions before these
are entirely deep frozen. The pellets are then transferred to
a final freezer to finish the process. The equipment can be
used to make pellets of sauces for ready meals, so that the
consumer can defrost just as much as he needs for a particu-
lar recipe. The freezer is delivered in one piece, tested and
immediately ready to use, which minimises installation and
start-up time. The standard size of the pellets is 30 x 30 x 6 mm,
but they can also be customised.
Typical products: Sauces
Pures
Soups
Pastes
CRYOLINECS compact spiral freezer
The CRYOLINECS, with its patented, self-stacking spiral belt
and its relatively small footprint of only 2.5 x 3.4 m, is capa-
ble of freezing and cooling large quantities of food products.
The unique design (the body of the freezer is built around
the belt) uses the coolant very efficiently. The self-stacking
belt also minimises the possibility of production stops due
to belt jams. Unlike most other spiral freezers, this unit can
be transported to the production site in one piece for rapid
installation and immediate start-up.
Typical products:
Meat and meat products
Dairy products
Fish and seafood
Ready meals and other
convenience foods
Bakery products

How to use little space for big benefits.Special freezing and cooling equipment.
CRYOLINETD triple-deck freezer
The CRYOLINETD is an in-line tunnel freezer which is used
for free-rolling products that can be dropped from one
belt to another without damaging. The unit has three beltswithin an insulated casing. The product travels along the top
belt first, then drops on and travels along a second and third
belt before moving out of the freezer. This process keeps the
product in the freezer for a longer time (in comparison with
the simple in-line tunnel freezer), significantly increasing the
cooling capacity while using a relatively small space.
Typical products:
Pasta
Diced meat
Shrimps
CRYOLINE
SP spiral freezersWhen a high capacity is required and there is no space for
a long (or several) tunnel freezer(s), the CRYOLINESP is
the ideal equipment. It is capable of freezing and cooling a
wide range of different products from pizzas to ice cream to
packed ready meals. The products enter on the low level and
travel along the spiral belt until emerging at the top level,
which gives them enough time to freeze (or cool) properly.
There are many different available sizes of this model, which
can be customised for specific requirements.
Typical products: Meat and meat products
Ready meals and other
convenience foods
Fish and seafood
Dairy products
Bakery products
CRYOLINERF rotary freezer
The CRYOLINERF is an in-line freezer with a rotating drum
specifically designed for free-rolling homogenous IQF
products. The products are fed into the unit on a fast-moving
belt to ensure separation, or pre-frozen in an upstream liquid
nitrogen immersion bath. Then, the products roll down the
length of the drum to finish the freezing. They exit below the
drum at the far end, where they can then be processed or
packed. This equipment is especially suitable for small, free-
rolling products that require gentle handling to ensure high
IQF properties (e.g. diced meat, shrimps or similar products).
Typical products:
Pizza toppings
Seafood
Diced meat
Vegetable pieces
Mushrooms

CRYOLINEAC coating tumblers
The CRYOLINEAC line was developed in order to meet the
demands of the ever-changing food industry. These freezers
are used to coat a wide range of basic products (e.g. meatpieces) with different sauces or marinades. The weight of
the coating can vary between 10 and 350 % of the initial
weight of the basic product. Its consistency ensures the
repeatability of the process and the high quality of the final
product. The unit can be pre-programmed for many different
products, making it easy to operate even by unskilled per-
sonnel. This innovative equipment will allow the producer to
lead the market with new and attractive products.
Typical products:
Pasta products
Noodles
Paella Shrimps
Risotto
Vegetables with sauces
Pan-cooked dishes
LIXSHOOTERMany products need immediate, on-site cooling before fur-
ther processing or in order to complete their production. One
of the best ways to do this is with the LIXSHOOTER. With
bottom injection of liquid carbon dioxide or liquid nitrogen,
a steady temperature can be reached while efficiently using
the cooling power of the refrigerant. Its unique, hygienically
designed valve fits flush to the vessel, preventing product
entrapment. The valves can be controlled separately or by
the control system of the vessel.
Typical products: Minced beef before forming
Liquid products
Other meat products before
forming
Confectionary products
Sauces
