Do You Know How To Choose Fish Feed Extruder Machine Correctly?

For a newly-built fish feed machine processing plant or an old plant to transform the original feed production line. When selecting an extruder, the type and specification of the extruder must be considered first, and the matching equipment must be determined according to the production capacity. Especially when the old plant is transformed, it should also be considered whether the production capacity of the original feed grinder, dryer and cooler can support the normal operation of the new machine. Specifically:

Puffing Effect Of Floating Fish Feed Machine

For floating fish feed processing, a good extruded effect directly affects the pellet forming rate to over 99%. It is generally considered that the requirements for qualified extruded feed are: the pelletizing rate is less than 1%, and the pellet floating rate (sinking rate) is as high as 100%. The formed particles are uniform in size, consistent in color and have good water resistance. Floating feeds are kept in water for 10 hours, and sinking feeds are kept in water for 3 hours without collapsing.

Investment Price Of Floating Fish Feed Extruder Machine

The investment price of twin-screw extrusion equipment is 1.5 to 1.7 times that of single-screw extrusion equipment with the same production capacity; the vulnerable parts and power consumption are about 1.5 times of the latter.

Service Life Of Fish Feed Production Machine

Equipment of different manufacturers has different service life due to different structural features and materials used. Therefore, when selecting equipment, special attention should be paid to whether the structural design is reasonable. The focus is on 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 real energy saving and consumption reduction. , Those raw materials that have not been superfinely pulverized have more serious wear on the vulnerable parts of the twin-screw extruder. In this case, it is more reasonable to use a single-screw extruder.
