---Dry method floating fish pellet machine,It isn't with steam conditioner,don't need the steam boiler.
Raw materials without conditioning before entering the extrusion system.

---Wet method floating fish pellet machine.It is with steam conditioner, need the steam boiler. 
Raw materials are conditioned before entering the extrusion system.

The purpose of steam conditioner:raise materials temperature,softening and to cure materials,to supplement the moisture to supplement the moisture content of raw materials.

The wet method floating fish pellet machine with higher working efficiency than dry method. 
After materials soften,spare parts such as screw,machine barrel with less damage.

Because of different raw materials character, before into extrusion system for dry method floating fish pellet machine and wet method floating fish pellet machine. 
For the wet method machine,it is damp,hot soft materials.For dry method,it is hard,cold materials.
