The first step in the process of conditioning is the application of a steam mixer. Steam treatment is necessary for optimal pelleting. By injecting dry steam (fluid and temperature), starch gelatinization is induced within a short period of time. The duration of conditioning can be extended by adding a Long Term Vessel in the process, behind the steam mixer.
Steam conditioning decreases mechanical friction during pelleting (which saves energy), improves pellet quality and pellet durability (PDI) for handling and transportation of finished feeds.
To facilitate an adequate supply of high quality steam, necessary for a proper conditioning process, Van Aarsen can provide a complete solution. For example a pressure regulator, which keeps the steam pressure to the mixer constant, water separators, proper pipe size and a provision that removes condensate close to the mixer to prevent excessive moisture in the mixer.
