Do You know How to Choose The Right Aquatic Feed Extruder?
For the new aquaculture feed processing plant or the original feed production line modified by the old factory, when using the extrusion extruder, the type specification should be considered first, and the matching equipment should be determined according to the production capacity. Especially when the old factory is rebuilt, it is also necessary to consider whether the production capacity of the original feed mill, dryer and cooler can support the normal operation of the new machine.
For the processing of aquatic feed, the good puffing effect directly affects the pellet forming rate, and the good can reach more than 99%. It is generally considered that the requirements for qualified expanded feed are: particle pulverization rate less than 1%, particle floating rate (sinking rate) up to 100%, uniform particle size, uniform color and good water resistance; floating feed in water can hold for 10 hours, the sinking type can be kept in the water for 3 hours without collapse.
The investment price of the twin-screw extruder is 1.5 to 1.7 times that of the single-screw extrusion equipment of the same production capacity; the wearing parts and power consumption are about 1.5 times that of the latter.
The equipment of different manufacturers has different service life due to different structural characteristics and materials used. Therefore, when selecting equipment, special attention should be paid to whether the structural design is reasonable. The key point is the wear resistance of the wearing parts and whether it can really reduce the screw wear. In addition, it is necessary to consider whether it can achieve the true energy saving. Those raw materials that have not been subjected to ultrafine pulverization are more serious to wear parts of the twin-screw extruder. In this case, it is better to use a single-screw extruder.
