How to Choose a
Fishmeal Plant |
|
LFP =
Lean Fish Plant
|
for
lean fish, fish-waste, tuna-waste, shrimp and shrimp-waste |
OFP =
Oily Fish Plant
|
for
oily fish, fish-waste and tuna-waste |
|
| |
General
: |
| |
Most fishmeal plants in
Asia process lean fish and fishwaste, and ASTW
“LFP = Lean Fish Plants” are very simple to operate
and maintain. Lean fish has max. 3% oil content
in the raw fish and can process anything, - raw
fish and fish waste and tuna scrap and bone with
intestines, even rotten fish, shrimp heads and
shell and semi dried fish. The number 24/55/90/120/160
indicates the capacity in fish input in tons per
24 hours.
An LFP
plant consist mainly of a heavy duty disc drier
that simply removes the water from the fish.”
Some types of fish like sardine, cat fish and
larger fish like some brands of tuna (including
intestine) have so much oil content that an ASTW
“OFP - Oily Fish Plant” must be used.
OFP
oily fish plants have more machinery, are more
complex and need higher skilled operators, and
also more automation is used for OFP plants. Waste
Heat Evaporators can be installed with OFP plants
to save up to 40% of the steam consumption.
Note that a LFP
lean fish plant can later be modified to be an
OFP oily fish plant.

Capacity

Fishmeal plants that
operate 46% of the year (250 days, 16 hours per
day out of 365 days
= 4,000 hours out of total 8,760 hours per year)
is considered good.
As a guideline, the break even
point for most fishmeal plants is about 25% operation
per year.
Buy the plant with 30-40% more
capacity than your average daily supply of fish.
Make sure that you during the high season can
process 100% of you fish supply, even if you have
to run 24 hours per day. Four tons of fish give
about one ton of fishmeal. The freshness of fish
and careful, low temperature drying is the key
to good fishmeal, mix the fish with ice if you
have to store the fish for a longer period of
time.

“A
good fishmeal plant shall run trouble free for
at least 10-15 years,
and is the reason
why fishmeal producers buy ASTW plants.” |

Description |
|
LFP 24 |
24-30 tons |
If the producer
has 10-12 tons of lean fish or fish
waste per day at low cost and no
plan to extendthe capacity later
on. Imagine that with 12 tons of
fish per day free of charge the
producer can pay backthe complete
plant within 6 months. Mostly bought
by small seafood producers with
fish waste.
|
|
LFP 55 |
55-60 tons |
Most sold plant
in Asia for medium sized seafood
producers and small fishing ports.
|
|
LFP-C 24
LFP-C 55
|
24-30 tons
55-60 tons |
The same plants
as LFP 24/55, but built as a packaged
plant mounted onto a 1(2)x40 foot
flat rack containers
complete with steam boiler, tanks
and accessories, ready to connect
electricity, fuel and start up.Air
cooled condenser mounted on top
as an option in case no water for
the deodorizer scrubber is available.
|
|
LFP 90
|
90-100 tons |
Most
sold plant with medium size capacity,
suitable for larger seafood
producers and medium size fishing
ports. Some customers who bought
LFP 50 later regretted that they
did not buy LFP 80 as they got access
to more fish than they were aware
of.
|
LFP 120
|
120-130 tons |
This
plant is starting to be big and
most used size for larger seafood
producers and fishing ports in Asia.
|
|
LFP 160 |
160-180
tons |
Most
sold plant and the largest single
line plant size available in Asia.
But in large fish meal nations like
Norway,Denmark, Peru and Chile,
plant size capacities range from
600-4000 tons fish per dayand the
fresh fish is immediately processed
to ensure top quality fish meal.

OFP 24
OFP-C 24
|
24-30 tons |
Installed mostly
in small seafood processing plants
that have oily fish. Low cost settling
tank available foroil separation
as a 3-phase decanter is hardly
feasible for such small capacity
plant.
For OFP - C 24, the plant is mounted
on 2 x 40 foot flat rack containers.
It is complete with boiler andtanks,
just to add accessories, hook up
electricity and water and start.
|
|
OFP 55
OFP-C 55
|
55-60 tons |
Many OFP 55 plants
sold as it is the smallest OFP plant
with full industrial capacity. The
protein rich stick water can either
be evaporated in the drier or thrown
away. 3-phase decanter and oil clarifier
separator for oil separationis feasible
for this size of plant. Mostly bought
by tuna processors. For LFP - C
55 The plant is mountedon 3 x 40
foot flat rack containers. It is
complete with boiler and tanks,
just to connect accessories, hook
up electricity, oil and water and
start.

OFP 90
OFP 120
|
90-100 tons
120-130 tons |
Medium- large size
OFP plants mostly used by tuna,
sardine and cat fish processors
in Asia.
These plants start to be big and
are installed near major fishing
ports and at large seafood processors.
3-phase decanter for oil separation
and oil clarifier separator. Optional
Waste heat Evaporator (WHE) is feasible
and can be installed to reduce the
steam consumption by up to 40%.
|
|
OFP 160
|
160 tons |
The
largest size OFP supplied in Asia.
With an optional Waste Heat Evaporator
(WHE) the capacity can increase
up to 220 tons/24 hrs. and the steam
consumption reduces at the same
timeby 40%. 3 or 2 phase decanters
and oil clarifiers are always installed
with these large plants.

| Tip:
|
Buy
the plant with 30-40% more capacity than your average
daily supply of fish. Make sure that you during
the high season can process 100% of you fish supply,
even if you have to run 24 hours per day. Four tons
of fish give about one ton of fishmeal. The freshness
of fish and careful, low temperature drying is the
key to good fishmeal, mix the fish with ice if you
have to store the fish for a longer period of time. |
