By utilizing the expander, harmful microbes and microorganisms such as salmonella and mold can be eliminated, ultimately improving the efficiency of the pellet mill. The hydraulic cylinder controls the conical outlet at the expander end, enabling adjustment and programming of the compression ratio, pressure, and temperature values based on specific requirements.
Automation allows for monitoring of the compression ratio via the switch on the hydraulic cylinder. The product is brought into contact with steam through steam heads located at various points on the expander sleeves, resulting in increased temperature under pressure.
To account for wear and tear, the expander screws are removable and replaceable over the shaft shaft. For optimal results, the expander should be used in conjunction with a lump breaker at the exit, which facilitates the distribution of the molded product and the consistent feeding of the pellet mill.
