How does the floating fish feed machine work?
Floating fish feed extruder machine is mainly composed of feeding system, raw material conditioning system and pellet extrusion system.
The material enters the modulator through the variable frequency screw feeder, and is gelatinized and matured by the high temperature, high humidity and high pressure in the modulator, and can also achieve the purpose of sterilization. After the material is modulated to a certain temperature and moisture in the modulator, it enters the extrusion system, is extruded, sheared and kneaded under the action of the screw, and finally is extruded from the die and cut into qualified pellets by the cutter.

Hammer mill SFSP66*80，Mixer 2m3/p，Single screw extruder，Box-type Circumfluent Dryer，Spraying machine，Cooler，Rotary screeter，packing machine30E，Square Plansifter，feed pellet machine，Feed Cooler，Packing machine，Steam boiler
Features of floating fish feed production line:
The entire floating fish feed production line is relatively compact and not very high. Due to the relatively small capacity and taking into consideration the specific circumstances of the customer, we did not equip him with an automatic batching system and chose manual feeding. However, in the packing section, the customer actively requested the use of an automatic packing system. The investment in the entire floating fish feed production line is not large.

Frequently asked questions
Why use a superfine grinder for the second grinding?
Since aquatic animals have low food intake, short digestive tracts, and poor digestive capacity, the raw materials used to produce aquatic feed require a very low pellet size to increase the digestibility of the feed by aquatic animals. Therefore, using an ultra-fine grinder to grind the raw materials for the second time can increase the grinding fineness of the raw materials and obtain higher quality aquatic feed.
The ultrafine grinders we produce are widely used in the crushing of various aquatic feed raw materials and can well meet the production needs of aquatic feed.
Why can’t grease be added directly into the mixer, but must be sprayed using spraying Equipment?
In principle, oils and fats can be added to the mixer and mixed with the raw materials. However, the fish feed extruder machine has strict requirements on the fat content in the raw materials during expansion and extrusion. When using a single screw extruder machine to produce aquatic feed, it is recommended that the fat content in the raw materials should not exceed 8%; when using twin screw extruder machine to produce aquatic feed, it is recommended that the fat content in the raw materials should not exceed 15%.
Therefore, in order for the fish feed extruder machine to work properly, the oil cannot be added directly into the mixer, but needs to be sprayed onto the surface and inside of the extruded feed using a sprayer after the extrusion is completed.
Is it necessary to have a boiler to produce extruded fish feed?
The boiler is not a must. The main function of the boiler is to provide hot steam to the modulator of the fish feed extruder machine to improve the maturation of the material.
However, fish feed extruder machine are divided into dry feed extruder machine and wet feed extruder machine. There is no regulator on the dry extruder, so there is no need to equip it with a steam boiler to provide hot steam.
If the feed formula contains some heat-sensitive raw materials, they will be destroyed by high temperature during feed extrusion. What should we do in this case?
The temperature in the fish feed extruder machine is relatively high, for example, for a twin-screw extruder machine, it can even reach 200 degrees. High temperature can improve the maturity and sterilization of materials, but at the same time, if the feed formula contains heat-sensitive raw materials, such a high temperature will cause certain damage to the heat-sensitive raw materials.
In this case, the heat-sensitive raw materials can be added directly to the oil to be sprayed without passing through the fish feed extruder machine, and then sprayed onto the surface and inside of the feed through the spraying machine.
