what is floating fish feed pellet machine?
there are two types of fish feed machines. this one is dry type, another type is wet type, we just talked about dry type in here. floating fish feed pellet making machine is single screw and dry type floating fish feed pellet machine which is mainly used to produce aquatic feed like for making fish feed pellet, tilapia feed pellet, catfish feed pellet, shrimp feed pellet, crab feed pellet, turtle feed pellet, goldfish feed pellet and so on. the finished pellet feed are puffed by high temperature through the heating plate in the machine. so the finished pellet can be floating on water about 24 hours because of being puffed.
and finished pellet size can be 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, and so on till to the bigger 15mm. this fish feed making machine is multi function, except for manufacturing floating fish feed, it can also process livestock and poultry feed.
the floating fish feed machine can be used to process single raw materials and pretreat animal waste and raw materials in the production of vegetable oil. it has various production capacity from 30 kg per hour to 5000 kg per hour, which is divided into small scale capacity and large capacity. small floating fish feed pellet machine has production capacity ranged 30kg/h-50kg/h, 60kg/h-80kg/h, 100kg/h-150kg/h, 180kg/h-300kg/h, 500kg/h-800kg/h, 800kg-1000kg/h and so other much bigger production capacity. these small fish feed making machine is very suitable for small fish farm, home use or small fish feed production factory. other production capacity like 1000kg/h or above usually used for industrial use and commerical use like floating fish feed manufacturing factory.
this floating fish feed pellet machine has two choices on power supply, it can be driven by eletric motor and diesel engine motor, diesel engine motor type is very good to the clients who has no 3 phase electricity or even no electricity at all. according to Wikipedia, Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. so you need a floating fish feed pelletizer machine to make your own fish feed for your fish farm.

This floating fish feed producing machine is an independent control box, which is fixed on the floating fish feed pelletizer machine
working principle of floating fish feed machine
During the extrusion operation, the material is input from one end of the cavity opening and conveyed to the entire cavity by the screw, Then the supplementary extrusion part is divided into several regions, A ring (pressure ring) is placed between each zone as a flow and pressure control, The conveying action of the screw pushes the material to flow through the annular gap between the pressure ring and the inside of the floating fish feed pelletizer machine cavity, The mechanical energy generated by the rotating motion of the screw is converted into heat energy due to the friction between the material and the various parts of the floating fish feed pellet machine and the internal friction of the material
As the material is extruded through the die hole at the end of the cavity, The dough-like material is processed into a certain shape, Due to the huge propulsion effect of the screw in the floating fish feed manufacturing machine cavity, a huge pressure is formed in the material, When these materials are extruded from the die hole, a large amount of water in the materials is vaporized in an instant, This greatly reduces the moisture content of the material
When producing low-density products, it would have a large expansion depends on the molecular structure of the material, and all condition and material used during the pelleting process
When producing high-density products, it would not expansion large depends on the purging pressure port on the cavity and all condition and material used during the pelleting process.

Dry type floating fish feed production equipment do not require a steam boiler, and it is cheaper and easier to use and operate than wet type floating fish feed making machine.
High temperature and high pressure increase gelatinization, which can kill bacteria in raw materials and make fish feed pellets easy to digest and absorb.
It is worth noting that the nutritional requirements of fish vary by species, size, growth stage and feeding habits. Depending on these differences in fish, different molds can be chosen to make pellets of different diameters and shapes. We provide different molds for customers to choose.
Application of floating fish feed pellet making machine
① It is widely used in the production of high-grade aquatic feed pellets such as fish, catfish feed pellet, shrimp feed pellet, crab feed pellet, turtle feed pellet etc.
② The final feed pellets have unique shape and good taste, high nutrition and smooth textures.
③ The floating time of the finished pellets on the water can be adjusted by the degree of squeezing, generally can be over 24 hours.
④ At present, the floating fish feed processing machine has become an ideal fish feed production equipment for small and medium-sized fish farms (catfish feed pellet, tilapia feed pellet, shrimp feed pellet, etc.) or fish feed manufacturing factory.
raw materials for floating fish feed machine
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
Innards : very suitable and ideal feed for catfish feed pellet making. It contain 52% protein.
The grinding fineness of raw materials of pellet feed above 1mm is required to be around 60-80 mesh. For pellet feed of 1mm and below, the grinding fineness of raw materials is generally recommended to be 100 mesh and above. After mixing a variety of raw materials, it is generally recommended to control the moisture at about 25-30%. For example, conventional raw materials will have about 10-13% moisture. On this basis, about 18% of water can be added, that is, 100kg of raw materials. Add about 18kg of water. Considering the different moisture content of different raw materials in different regions, the amount of water added can be controlled according to the actual situation.
In principle: the maximum particle size should be less than 1/3 of the diameter of the die hole

maintenance of floating fish feed making machine
The inside and outside of the fish feed production equipment should be cleaned after each shift, especially the material should not be retained in the extruding chamber, so as to avoid it being difficult to clean up after cooling and agglomeration;
(Suggestion: when not producing on the same day, please fill the extruding chamber with water and soak it until the next day, this will be easy to clean.)
Pay attention to frequent cleaning of the large pulley of the main shaft of the puffing cavity, and do not accumulate too much dust, otherwise the belt will be unbalanced and cause the puffing cavity to vibrate. Regularly check the tightness of the belt;
The main bearing of the expansion chamber of the floating fish feed pellet machine is lubricated with lubricating oil, and the bearings of the feed conditioner and its transmission device and other bearing parts are lubricated with grease.
No. 2 lithium base grease must be added to lubricate and protect the sealing ring of the material seal of the feed extruding cavity every shift
When replacing vulnerable parts (extrusion screw, steam plug, gasket, etc.), tap with a copper rod, and do not hit hard with hard objects.
It is strictly forbidden to place heavy objects or stand on the puffing cavity
Raw materials should be cleaned, and foreign objects such as metal are strictly prohibited from entering the machine
If the extruded material is not used or replaced for a long time, the material in the hopper and extruding cavity (group) should be cleaned to avoid agglomeration, mildew or cross-contamination between materials
Check belt tightness monthly between the floating fish feed pellet machine and electric motor or diesel engine motor
Adjust and operation of floating feed pellet machine
Note: blades needs to be close to the mold,make blades bend slightly and turn it clockwise by hand lightly,not press too hard. when use, adding a little of oil between the blade and the mold.
Note: The bearing box of DGP60 and below models is filled with high temperature resistant butter, which can be injected through the grease nozzle on the side of the casing.
① Check the fasteners and connecting parts, and there must be no looseness
② Observe the bearing box oil mark, whether it is higher than the horizontal plane of the bearing box center,If it is lower than this level, the oil should be supplemented (No. 60 oil in summer, No. 40 oil in winter);Lubricate each shaft end bearing
③ Check whether the connection between the electronic control system and each load is correct
④ Adjust the tensioning screw at the end of the guide rail of the main motor base to make the belt tension appropriate.
⑤ Remove the discharge box (together with the subsequent equipment of the discharge box),Slowly turn the main shaft counterclockwise, when there is no obvious friction sound, then tighten the bullet counterclockwise. (without loading box and subsequent equipment)
