Floating Fish Feed Machinery
Specification
Flow chart: flour mixing-screw covneying-extruding-sifting-air conveying-drying-flavoring-packaging.
Raw materials: corn flour, rice flour, wheat flour, fish bone meal, chicken powder, glycerol etc.
Voltage: normally 380v, 50hz, 3 phase, also can customize as client's local voltage.
Adopt Siemens motor, prolong the machines usage life.
Siemens PLC and touch screen make the line more easier to operate, the fault will display on the screen directly, no need to check the machine one by one.
