Fish Feed Pellet Machine

Technical Features of Floating Fish Feed Mill

1. This fish feed machine adopts the auto-controlling speed feeding tool to produce the feed material evenly.
2. Electric heating device is adopted which can improve the feed expansion rate and pellets floating time.
3. High temperature and high pressure cooking process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.
4. The cutting knife adopts the frequency controlling speed in order to change the material size.
5. The floating time can be controlled by the puffing degree adjustment.
6. Auto-temperature control system makes the temperature controlling more direct viewing and the parameter more precise.

Difference Between Dry and Wet Fish Feed Extruder

Fish feed making machine can be divided into dry type and wet type fish feed extruder according to the moisture of the raw materials.

1. Dry type

Heating the materials by the frictional force, this floating fish feed extruder machine squeezes raw materials out of the holes of the mold under the action of screw extruder. The pressure and temperature of the pellets sharply decreases when coming out of the machine, and the moisture evaporates. Then materials are puffed and become pellets with porous structure. During the process, the moisture ranges from 15 to 20 percent.

2. Wet type

The working principle of wet type is similar to dry type. But the former needs to add water or steam into the machine to increase the moisture to 20 percent, or more than 30 percent during the process. It increases the temperature of the materials by steaming. Different from the dry type floating fish feed pellet mill, the wet type is equipped with a boiler which can continuously steam the materials to make pellets. It is a crucial machine for making high-quality fish pellets and pet food.

Fish Feed Pelleting Machine

The Feed pelleting machine (flat-die pelletizer) is used for converting feed ingredients that are in mash form into dry pellets resulting in strong, smooth pellets that are good for feeding livestock. Thus, it turns mash feeds into pellets without adding water, producing various sizes of pellets – 2mm for Juveniles, 4mm for post-juveniles as well as 6mm and 8mm. The size of pellets you choose to produce depends on the age and size of the fish.

Flat die type fish feed pelleting mill

Flat die pellet machine adopts belt, worm gear and worm wheel mechanism, with the smooth rotation, low noise, material feeding relies on its own gravity, to avoid clogging. The speed of the spindle is about 60rpm, the line speed of the roller is about 2.5m/s, which can effectively remove the gas in the material and increase the tightness of the product. Because of low speed, reduces noise and component wear at run time, it can produce high fat and high sugar honey products. Roller bearings have permanent lubrication and special seal, which can prevent the lubricant polluting feed raw material in granulating process and reduce the loss of lubricant. Flat die type fish feed pelleting machine has a variety of aperture and compression ratio of the flat mode to choose, φ1-8mm. According to different needs, the user can choose the flat mode with different aperture and compression ratio to obtain the best technical and economic benefits.

Features of flat die fish feed pellet machine

1.Dry into and dry out (raw material moisture is not less than 13% of the national export volume of water), using differential mechanism, universal joint driving. Adopting electric motor or diesel engine makes it low energy consumption, high yield, easy operation.

2.Using the new technology of extrusion granulation and polishing, which completely solved the traditional granulation process of low organic raw materials(about 30%), the difficulty of granulation, raw materials need to dry grinding and other key technical problems. A model of this machine uses three times extrusion, the pressing area is increased to 3 pressing wheels, the inclined roller can reduce friction and energy consumption, increase production.

3.It can produce different shapes of feed particles; and the particle is uniform, smooth, round the whole, high strength, good mobility.

4.It use the unique process of three in one machine to complete the whole process of low temperature drying, cooling, screening process. Less equipment investment, low operating cost.

5.It’s widely used in animal husbandry, aquaculture, large or small farms, feed plant and other industries. It is the preferred ideal equipment for feed production enterprises.

Ring die type fish feed pelleting mill

The ring die fish feed pellet machine should be more familiar than the flat die type, because many domestic and foreign feed companies are using ring molding machine. The raw material is fine feed, such as corn, soybean meal, cottonseed meal, and so on, the adhesion rate is high. In addition the granulation with steam conditioner, can advance to the softening and curing effect on the material, and thus better granulation, increase particle gloss. Ring die fish feed pellet mill is the main feed machinery and equipment in the production of pellet feed, its performance largely determines the production output, occupies a very important position in the process of feed processing.

Main performance and characteristic

1.Simple structure, wide applicability, small floor area, low noise.

2.Powder feed, like grass powder, do not need to add a little liquid. Therefore, the moisture content of pellet feed is basically the moisture content of the material, which is more conducive to the storage.

3.Pellet feed can obtain higher economic benefit than mixed powder feed.

4.The pellets produced by dry material have high hardness, smooth surface and internal curing, can improve digestion and absorption of nutrients.

5.The forming process of particles can make the grains and legumes trypsin resistance factor in degeneration, reducing the adverse effects on the digestion, can kill all kinds of parasite eggs and other pathogenic microorganisms, reducing the variety of insects and diseases of digestive system.

The differences between flat die feed pellet machine and ring die feed pellet machine

* Feeding way: ring die pellet machine adopts mechanical force feeding into granulating chamber under high speed rotating centrifugal power, through the scraper to distribution of material, feeding is not uniform; flat die pellet machine relies on the weight of the material itself into the press room, which can uniform feeding.

*Pressure: in the mold under the same diameter, the diameter of ring molding wheel is limited by the diameter of ring mold, so the pressure is limited; the diameter of flat molding wheel is not limited by the diameter of flat mold, it can increase the bearing inner space. Selecting of large bearings to enhance the bearing capacity of the press wheel is not only improve the roller pressing force, but also prolong the life.

*Discharge mode: the ring mold has a high speed, the damage rate is high when the material discharged; while the flat mode has low speed, so the damage rate is low.

*Press wheel adjustment mode: ring die fish feed mill uses the two screws, which are on the eccentric wheel in the middle of the press wheel, to adjust pressure; flat die granulating machine is adopt screw thread column center adjusting mechanism, one hundred tons top force, falling steadily, soft touch, uniform pressure. Rotating manual and hydraulic automatic, the two ways can be used.
