The shrimp feed pellet machine is a special pelleting equipment used for processing black tiger shrimp feed, crayfish feed, freshwater shrimp feed, giant river prawn feed, whiteleg shrimp feed, and other types feed of production. Shrimp feeds are fast-sinking pellets. They retain their elastic form after hours in water.
Shrimp feed can be produced by two methods, pelleting or extrusion, depending on the dietary of the shrimp species.
Pelletized Shrimp Feed
For shrimp feed applications we offers conventional and
well-proven pelleting process lines using ring dies and post conditioners
Pelletized Shrimp Feed Processing Flow
Extruded Shrimp Feed
Extrusion of shrimp feed as an alternative to pelleting enables feed producers to make a more nutritional high value product.
Extruder Shrimp Feed Processing Flow
Setting up a shrimp feed pellet mill to produce high quality pelleted feed for shrimp/prawn would be a great choice for shrimp farmers and shrimp feed producers.

Step 1 : Raw Materials Quality Check
Domestic and imported raw materials that reached our factory will be checked in our inhouse laboratory based on different parameters like Protein, Fat, Moisture, Appearance, Toxins, Fiber etc. Only material that passes our stringent standards will go into our feed.
Step 2 : Batching
Each batch of different raw materials will be weighed as per the formula. We use precision computer automated batching system to get accurate weights for every batch.
Step 3 : Premixing
Materials are that are weighed based on formula will be mixed with premixes to form a uniform material that will be fed into coarse grinding.
Step 4 : Coarse Grinding
We use fine hammer mill to grind all materials into moderately fine powder.
Step 5 : Fine Grinding
Shrimp mouths are very small, so it is very important to grind materials into very small particles so that shrimp can feed on them. We use latest generation high intensity pulverizes to fine grind feed. The technicians need to check each batch after pulverizing to make sure that feed is grinded to required fineness.
Step 6 : Second batching & mixing
Fine powder feed coming from ultrafine-pulverizer will be mixed with vitamins, minerals and other medicines, Fish oil, Lecithin etc. to get uniform mixture. We use ultramodern mixers to get at least 98% uniformity, This step is very important because this ensures that all pellets get uniform composition of nutrients so that all shrimp get same nutrition.
We extensively automated this step to ensure highest quality shrimp feed. All Fish oil, Lecithin, Water are weighed and spayed directly by computer so that it will be accurate for each and every batch.
Every time to make sure medicines and vitamins and minerals are mixed an alarm will sound only after worker confirms mixing complete machine restarts, this whole process is videotaped. All mixing and spraying times are controlled by computer to make sure every batch will be mixed.
Step 7 : Pre-Conditioning
Mixed feed from previous step will be cooked in steam in this process, this increases digestibility as well as water stability. Our pre-condition system uses 4 step process, this is most modern available in the world. We tweaked it to give more condition time than any other system in the world.
Step 8 : Pelleting
This cooked feed will be made into small pellets. Our shrimp feed pellet machine system based on 30 years proven pelleting & extrusion technology can make the 1 -3mm pellets.
Step 9 : Post-Conditioning
Pellets made in pelletizer for shrimp feed will be further cooked (conditioned) in Post-Conditioner, this not only increases digestibility of feed, also increases water stability further. Our special post conditioning system is enhanced to give at least one our post-conditioning, as well as choice of direct or indirect steam.
This system is further automated with computer system to make sure always same steam heat is maintained
Step 10 : Drying
Pellets from post conditioner will be dried to decrease moisture to store it.
Step 11 : Cooling
Pellets will be cooled to room temperature to store in bags.
Step 12 : Crumbling (Only for Starter Feeds)
Crumbling is optional step for starter feeds. Crumbling will break pellets in 1,2,3 size crumbles to be small for PL size shrimp.
Step 13 : Screening
Small shrimp pellet pieces, powder and big lumps will be screened out to filter required length pellets.
Step 14 : Packing
In final step, shrimp pellet feed will be weighed and packed in bags by automated packing system. This is hands free system, no workers will touch feed in the process, this avoids contamination by hands, and computer weighing provides accurate weighing of bags.
Choosing the right ingredients is important to making a shrimp feed that provides the nutrients your shrimp need to grow. Some ingredients commonly used to make shrimp feed pellets include:
Soybean meal has one of the best essential amino acid profiles of all protein-rich plant feedstuffs. Soybean meal with hulls (44 percent crude protein) and dehulled soybean meal (48 percent crude protein) are available in large quantities. These products are used in shrimp and prawn feeds. Marine shrimp appear to be able to digest soybean meal very efficiently.
2. Wheat
The wheat used in making shrimp feed pellets has two functions. One is it provides a good amount of carbohydrates to shrimps and the other is it releases gluten which is used as a binder to make pellets.
3. fishmeal
Fishmeal is a rich source of high quality protein, has relatively high-energy content and is rich in important minerals such as phosphorus, B vitamins and essential fatty acids.
4. fish oil
Fish oils and squid oils provide essential fatty acids required by shrimp
