How to choose a Fishmeal Plants

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.
 
And 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 =  Lean Fish Plant, for lean fish, fish-waste, tuna-waste, shrimp and shrimp-waste.   

Plant  size Capacity (ton./24 hrs.) 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 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 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 120 120-140 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 top quality fish meal.
     

OFP = Oily Fish Plant, for oily fish, fish-waste and tuna-waste

Plant  size Capacity (ton./24 hrs.) Description
OFP 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.
OFP 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. 
OFP 90
OFP 120
90-100 tons
120-140 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.
