Freezing & Cooling 3

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

Flexible choice of models

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

and reducing the risk of contamination. There is also the

possibility to download information from the controller for

traceability purposes.

Typical products:


Dairy products

Fish and seafood

Ready meals and other

convenience food

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:


Dairy products

Fish and seafood


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


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
