What Should I Pay Attention To When Purchasing Fish Feed Mill Machine?

Many users do not know how to choose a model when purchasing a pet food extrusion machine. Next, we will briefly analyze it for you. When choosing a fish feed machine, you should focus on the following issues:
1. Puffing effect
In terms of using fish feed pellet machine to process aquatic feed, the fish pellet machine with good puffing effect has a particle forming rate of more than 99%, a particle powdering rate of no more than 1%, and a particle floating rate (sinking rate) of 100%. Uniform particle size, bright and consistent color, good water resistance; floating aquatic feed can remain in water for 10 hours without collapsing, or sinking aquatic feed can remain in water for 3 hours without collapsing, etc.

2. Investment price
The investment cost of fish pellet making machine is 1.5 to 1.7 times higher than that of a single-screw extruder with the same production capacity; the cost of wearing parts is about 1.5 times that of a single screw; and the power consumption cost is about 1.5 times that of a single screw.
3. Service life
Due to the different materials and structural characteristics of fish feed production machines from different manufacturers, the service life is also different. Therefore, when choosing a floating fish feed making machine, you should pay attention to the wear resistance of some wearing parts and whether the structural design is reasonable; in addition, you must also consider whether the puffing equipment can truly achieve the purpose of energy saving and consumption reduction. For micro-crushed raw materials, the wearing parts are more likely to wear. In this case, it is more reasonable to choose a single-screw extruder.
