The molds for producing small pellet aqua feed by feed expanding machine are generally 1.2mm.1.0mm and 0.8mm, even some manufacturers require to process the expanded pellets with a pore size of 0.6mm.
The advantage of small pellets processed by the application process is the relative ease of production. The cost is relatively low, but the high cost of its formulation, the high powder content, the poor water stability and the high amount of recycled material make everyone prefer the indirect production using the puffing machine. The puffing machine is used indirectly for small granule puffing, which has the advantages of low formula cost, low powder content, good stability in water and handsome surface.
