The feed expander is used for high-temperature conditioning of feed mixtures, conditioning and stabilisation of mixture before pelleting and thermal treatment and crumbling of feed mixtures and individual raw materials.
|
|
An efficient solution for securing:
- Lower percentage of fines
- Better physical pellet quality
- Increased pellet mill capacity
- Increased liquid addition
- Better possibilities of raw material composition with less consideration for binding properties of raw materials results in low cost formulating
- Improved activation of the natural binding properties of raw materials
- Reduction/elimination of bacteria
- Reduction of growth-inhibiting substances
- Better digestibility of the feed compound
|
Design:
- High capacity self-centring expander screw for kneading, compressing and heating of the mixture
- Variable outlet nozzle, automatically controlled
- Heating by friction and steam injection
- Easy/quick access to nozzle and screw
