What is floating fish feed production line?
floating fish feed production line is a full complete and automatic fish feed production plant. The complete floating fish feed pellet production line includes fish feed pellet machine, fish feed crusher, fish feed mixer, fish feed dryer and other necessary equipment. The floating fish feed plant can process corn, soybean, wheat, grains, protein, fish meal, bone meal and other raw materials into pellets, and finally manufacturing granules with different shapes, unique flavors, rich nutrition and fine texture, which are widely used in production goldfish feed, tropical fish feed, catfish feed, shrimp feed, turtle feed and other aquatic feed.
this floating fish feed mill plant is multifunctional, it can also produce pet feed like for dogs, cats, etc. the floating fish feed manufacturing plant is the best choice for large and medium feed factories and farms. This fish feed processing line has different output for customers to choose from large to small.there are 300 kg/h, 500kg/h, 1000kg/h, 2000kg/h etc. on the production capacity.
This floating fish feed processing plant is newly developed by our factory to meet the needs of intensive production of kinds of fish feed pellets. The floating fish feed production line has many specifications, and can produce floating fish feed, sinking fish feed, pet feed, livestock feed, etc.
what equipment needed for floating fish feed plant
fish feed crusher machine
The raw materials should be crushed to the required particle size by a fish feed crusher machine. Raw material crushing is a crucial step, if the crushing fineness is not up to the requirements, problems may occur in the production of floating fish feed, below is the requirement for fineness of crushed raw materials.
Requirement of raw material crushing fineness for processing floating fish feed
| die mold aperture φ (mm) | grinding fineness required |
| 1.0 | 95% reach to 90-100 mesh |
| 1.5 | 95% reach to 80 mesh |
| 2.0 | 95% reach to 80 mesh |
| 3.0 | 95% reach to 60 mesh |
| 4.0 | 95% reach to 60 mesh |
| 5.0 | 95% reach to 60 mesh |
fish feed mixer machine
When using a variety of different raw materials to manufacturing fish feed, mixing is necessary, and the full mixing of materials can ensure production efficiency and improve feed quality.
floating feed extruder machine
extruder machine is the most important equipment in the entire production line and it is the core part of the production of floating fish feed, powdery raw materials are finally formed into floating pellets through the extruder machine.
fish feed dryer machine
Why do you need a dryer? When producing fish feed pellets, 25%-35% of raw materials are required to be added. If the finished feed pellets are not dried, it will not be easy to store, pack and transport.
fish feed cooler machine
It’s already dried up in front and already easy to store and pack, so why do you need a cooler? Because the moisture in the pellets is evaporated by steam or high temperature during drying to achieve the purpose of drying, but the temperature generated by the steam or high temperature during the drying process is very high, if it is not cooled and stored or packaging directly, the temperature will generate moisture and affect storage and packaging.
the above are the main equipment needed in floating fish feed production, There are other auxiliary equipment such as conveyors, silos, packaging machines, etc., customers can choose according to their needs.
floating fish feed manufacturing process flow chart
The fish feed production process can be divided into two types in terms of technology and equipment flow
Technological Procedure:
preparing raw materials → crushing raw materials → mixing raw materials → transporting raw materials → extruding raw materials → transporting finished pellets → drying finished pellets → cooling finished pellets → screening finished pellets → spraying oil → seasoning → automatic packaging
Equipment Needed Process:
crusher machine → mixer machine → conveyor machine → extruder machine → conveyor machine → dryer machine → cooler machine → vibrating screen → conveyor machine → oil spraying machine → automatic packaging machine
features of floating fish feed mill plant
the floating fish feed mill plant has advanced technology, high capacity and low energy consumption.
The modular structure is convenient for assembly and disassembly, facilitating the shipment and installation.
PLC controlled the whole floating fish feed manufacturing plant, alarm device is available. The operation is simple and convenient.
Final pellet shapes and sizes can be various by changing the mould. For fish and shrimp feed pellet, the floating time in water can be adjusted by the extrusion degree adjustment.
Processing is processed at high temperature instantaneous process, greatly reducing the decomposition of nutrients in feed, at the same time improve the protein (through the degeneration of protein) and starch (through starch paste) digestibility, to improve the palatability of the product.
In order to ensure the quality and the capacity, there is the special pressure-increased device. Besides, the electric heating device improve the feed expansion rate.
raw material for floating fish feed production
corn,maize,soybean, rice : contain about 10-14% of protein and also contain vitamin B1, B2, B6 and small quantity of enzyme.
straw meal,grass meal,rice bran,wheat chaff: contain fiber, control many types of fish diseases
Mustard Cake: Mix maximum 40% of cake in the fish feed. But don’t use dry cake more than 20%. Mustard cake contain 30-32% protein
cotton seeds,sunflower seeds,rapeseed: contain about 54% protein. It is a better ingredients for supplementary fish feed.
fish meal,fish oil: easily digestible to fish. Fishmeal contain about 55-60% protein.
bone powder: very necessary for building fish-bone. The ratio of calcium and magnesium in the bone dust is 2 : 1
floating fish feed raw material sources
Fish food should ideally provide the fish with fat (for energy) and amino acids (building blocks of proteins) and the fish food (whether flake or pellet) must be speedily digested in order to prevent buildup of intestinal gas, kidney failure and infections (such as swim bladder problems and dropsy) and to avoid aquarium pollution due to excessive ammonia. Aquatic diets for carnivores must contain vegetable matter such as spirulina. floating fish feed raw material sources can be from below ways according to wikipedia
Fish meal (protein source) have two basic types: (a) those produced from fishery wastes associated with the processing of fish for human consumption (such as salmon and tuna) and (b) those from specific fish (herring, menhaden and pollack) which are harvested solely for the purpose of producing fish meal.
Shrimp mix (shrimp meal) is made from cull shrimp that are being processed before freezing or from whole shrimp that is not of suitable quality for human consumption. The material to be made into shrimp meal is dried (sun-dried or by using a dryer) and then ground. Shrimp meal is a source of pigments that enhances the desirable color in the tissues of fish. It is also a secondary supplemental protein source for fish.
Squid meal is made from squid viscera portions from cannery plants including the eggs and testis. Squid Meal is a highly digestible protein source for fish which provides a full range of amino acids, vitamins, minerals and cholesterol (1.0–1.5%) of cholesterol suitable for fish fry and young fish.
Brine shrimp (adult Artemia) is a common food source for fish that are available in adult-form, as eggs or freeze-dried. Brine shrimp is a source of protein, carotene (a color enhancer) and acts as a natural laxative in fish digestive systems. Brine shrimps can also supply the fish with vegetable matter due to their consumption of algae.
Soybean meal is a high protein source for fish and has become a substitute for traditionally-used marine animal meals.
Spirulina is a blue-green plant plankton rich in raw protein, vitamins A, B1, B2, B6, B12, C and E, beta-carotene, color enhancing pigments, a whole range of minerals, essential fatty acids and eight amino acids required for complete nutrition.
Whole wheat (carbohydrates) is not the best source of energy in fish but is an excellent source of roughage for fish such as Goldfish and Koi. It is also a natural source of vitamin E which promotes growth and enhances coloration.
