company news about Considerations when choosing a puffing machine

In the new aquatic feed processing plant or the transformation of the original feed production line, the choice of extrusion machine should first consider its type, according to the feed production capacity to choose a matching extrusion machine; especially when the old plant transformation, should also consider the original crusher, dryer, cooler production capacity is sufficient. Selection should focus on several issues.


For aquatic feed, good puffing effect is the particle forming rate of 99% or more, particle pulverization rate of less than 1%, particle floating rate (sinking rate) 100%, uniform particle size, color, with good water resistance; floating aquatic feed in the water to maintain 10h, sinking aquatic feed in the water to maintain 3h does not collapse, etc..


Different manufacturers of extruded puffing machine due to structural features and the use of different materials, service life is not the same. Therefore, in the choice of extrusion machine, special attention should be paid to the wear resistance of some wearing parts, as well as its structural design is reasonable, whether to reduce the purpose of screw wear; in addition, in the choice of extrusion machine to consider whether the machine can really achieve the purpose of energy saving and consumption reduction. For the raw materials without superfine powder, the wear and tear of the wearing parts will be more serious, especially the twin-screw extrusion puffing machine, this situation is more reasonable to choose a single-screw extrusion puffing machine.
