Description of the extruder for dog/fish food

Our Pet food processing line is consists of Mixer, Conveyor, Extruder, Air conveyor, Dryer and Flavoring system. With abundant experience and advanced technology, our machines are enjoying a high market and we get high reputation from our customers all over the world.

The production process

1. The gearbox:

New-style project of parallel three-axises driving makes the conveyaxis, convey chain, decelerate and the 

torque assignment get together, which keep it compact, and the key bearings are imported.

The select material of drive components is dainty. Including super intension alloy cementation steel, cementation and quenching, gear grinding techniques, strengthening of tooth face. So they can ensure high 

torque, high precision and low noise. Soakage and coerce lubrication integrate smoothly. 

When the hydraulic circuit is over pressed, it alarms.

2. The feeding system

Metering feeders are equipped with single screw, twin screw, hollow screw, forced-feeding, side feeding, liquid-adding system, etc, and it is depend on the condition of the pet food raw material.

3. Screw         

The screw elements and then kneading blocks are designed accurately, by precise processed, agile combination,

with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming.

The screw material is made of high tool steel 38CrMoALA or W6Mo5Cr4V2 by special heat-treatment.

4. The barrel       

Euro-style rectangle barrel, reflux refrigeration is optimized and disposed, which makes temperature 

difference in C areas smaller. According to the material and special techniques demands, the material 

of cylinder can use high quality nitraded steel, corrosion proof or antifriction with corresponding process.  

5. The heater

Innovated design of heater tightened style insures high efficiency of heat transfer and high longevity of 

heater.

6. Pelletizing

Various modes of pelletizing, such as water-cooling strand, air-cooling pelletizing, water-ring pelletizing, under water pelleting, etc.
