haarslev industries manufactures processing

equipment to customers in the meat, pet food,

fish, oil, environmental and biofuel industries

world-wide. Plant durability, reliability and excel-

lent service are keywords for our supplies, wheth-

er it is a single piece of equipment or a complete

turnkey plant. our wide range of equipment, all

designed for specific applications, form an ideal

basis to design and optimise fish meal plants as

well as to upgrade existing plants.

f i s h M E a l a n d f i s h o i l

although fish meal processing generally follows

the same principle, the process requirements vary

from one area to another and from one plant

to another. freshness of the catch, type of fish,

requirements for meal and oil quality and envi-

ronmental issues dictate the need for individual

plant solutions. We offer a full delivery pro-

gramme to meet such challenges.

fish meal plants from haarslev industries operate

all over the world. our delivery programme

ranges from small land-based or ship-based units

and up to the largest fish meal plants in the

world. our plants are known for maximum energy

efficiency, reliability, safety and compliance with

local environmental standards.

haarslev industries history within the fish meal and oil industry goes back many decades in time.

Thus we have gained vast experience and extensive know-how in fish meal processing that enables us to

provide a unique equipment programme for turning raw materials into high grade products

while taking energy effiency and the environmental protection into account.

We have in-house engineering and manufacturing facilities in Europe, south america and asia.

We are the preferred supplier in major fish meal producing countries and represented

world-wide through our own locally operating staff and agent network.

f i s h P r o c E s s i n g

Whether a plant is processing whole fish or fish

by-products, the first step is the cooking process.

haarslev industries cookers are indirectly steam

heated. after cooking, the fish passes through a

strainer, and a large amount of liquid is drained

off before the solid material proceeds to mechani-

cal dewatering in the twin screw press.

high-grade fish meal sells at high market prices

because this type of meal has shown significant

advantages in aquaculture and animal breeding.

This is difficult to replace with proteins of other

origin. haarslev industries develops special cook-

ing and drying equipment, which limits the expo-

sure of the fish to high temperatures. The result is

a better preservation of essential amino acids and

that digestibility remains as high as possible. our

plant design focuses on optimum utilisation of

both raw materials and energy.

E v a P o r a T o r s

haarslev industries evaporators increase the plant

yields and reduce the overall energy consumption

while minimising the environmental impact.

Proteins in the liquid from the strainer system

and the twin screw press account for up to 30% of

the total fish meal yield. after separation of the

oil, the evaporator concentrates the stick water

making it possible to exploit the suspended and

dissolved proteins. By adding the evaporator con-

centrate to the fish meal you get an end product

containing all the nutrients available in the raw

fish. This maxi mises the plant yield and solves an

environmental challenge as well. The haarslev

evaporators can utilise waste heat from the steam

dryers and thereby make the overall fish meal

processing highly energy efficient.

c o M P a c T P l a n T s

haarslev industries also supplies compact fish meal

plants with all machines mounted as one unit.

This includes cooker, strainer, twin screw press and

dryer. separately, an oil recovery system and an

evaporator can be installed.

our compact plants are pre-assembled and ready

to install either on board floating factories or

ashore for treatment of by-products from fish

processing.

Mechanical dewatering with the twin screw press

is very cost efficient and adds energy savings to

the overall fish meal production. The twin screw

press has been optimised to ensure that the press

cake always has the best possible quality. The twin

screw press is of a very robust and sturdy design,

which ensures high cake dryness at low rotational

speed on the screws.

liquid from the strainer and the press is collected

for further separation into oil and stick water.

The latter is fed into an evaporator, which concen-

trates the remaining proteins by utilising waste

heat from steam dryers. The concentrate is now

added to the press cake and all material is dried.

This method ensures that almost all valuable pro-

teins are utilised and that meal yield and quality

increase.

d r y E r s

our dryer programme for the fish meal industry

is the largest in the market. it ranges from a

number of different designs of contact disc dryers,

indirectly steam heated for both atmospheric

and vacuum operation, to a selection of indirectly

and directly heated hot-air dryers available for

the production of special meals with special

characteristics.

Moreover, haarslev industries has specialised

in combining different dryer models, which

enables the production of special meal qualities

at minimum costs. The complete haarslev

dryer programme is backed by comprehensive

engineering and innovative activities, allowing

us to provide tailor-made drying solutions for

special needs.
