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."

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 extend
the capacity later on. Imagine that with 12 tons of fish per
day free of charge the producer can pay back the 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 2x20 and 4 x 20 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 55 later regretted that they
did not buy LFP 90 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 |
This plant is starting to be big and most
used size for larger seafood producers and fishing ports
in Asia. 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 day and the fresh fish is immediately processed to
ensure topvquality 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 for
oil separation as a 3-phase decanter is hardly feasible for such
small capacity plant. For OFP-C24, the plant is mounted on 2 x 20
foot flat rack containers. It is complete with boiler and
tanks, 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 separation is feasible
for this size of plant. Mostly bought by tuna processors. For
LFP-C55 The plant is mounted on 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 |
160-180 tons |
The largest size OFP supplied in Asia. With
an optional Waste Heat Evaporator (WHE) the capacity can
increase up to 240 tons/24 hrs. and the steam consumption reduces
at the same time by 40%. 3 or 2 - phase decanters and
oil clarifiers are always installed with these large
plants. |
