Because of the special environment of aquatic feed use and feed requirements,aquatic feed is basically take the granulation forms, it can improve the feed conversion rate, improve the feed palatability, reduce the feed coefficient, increase the stability of feed water, in the manufacture of particles during kill harmful bacteria,improve the storage performance of health care and feed the fish and shrimp the. Thepellet type with extrusion die, die; feed grain production can be divided into puffed pellet feed, hard pellet, soft pellet feed pellets in the water; according to thecharacteristic and is divided into the sinking particles, floating particles and otherspecies. In the high-grade aquatic products breeding, generally taken to be the fed extruded pellet feed. In the ordinary in aquaculture, generally taken to be the feedingof hard particles in feed, aquaculture, usually fed fresh soft pellet feed, but should pay attention to the feed storage time and storage temperature; also has a feeding part of extruded feed. Friends should be in the aquaculture under the guidance of experts,the choice to buy feed particle machine you breed suitable.

Existence of feed particle machine at present poor quality problems:

1 safety protection measures, such as in the specification is not clear operational safety, overload protection device, iron removing device, transmission device, the linkage door interlocking device, safety warning signs such as project requirementgaps.

2 backward technology and poor manufacturing quality, consumption of electricity per ton project caused by particle machine exceed the standard, increases the user cost of production.

3 particle formation rate is low, the water stability is poor, is due to the pore size of the template is not reasonable, feed ripening degree is not reasonable, due to low particledensity.

4 high noise, is due to the assembly and parts processing quality difference caused by the.

The 5 template roller cutter, screw extrusion and other components of the material choice is not reasonable, do not heat treatment or heat treatment is not correct, thecomponents of the corrosion resistant performance is poor, will affect the normaloperation and feed equipment appearance and inner quality. General puffing particlemachine screw life should be in 1000 hours or more, a small flat molding die lifeshould be in 1100 hours or more, a ring molding die life should be in 600 hours.
