Feed Enhancement Technology FET

Get in touch about this product

Significantly improved feeding capacity and throughput rates

In this patented technology the feeding zone of a ZSK extruder is equipped with a porous, gas-permeable wall section to which a vacuum is applied externally. The resulting gas extraction increases the material intake capacity in the processing of feed limited products by up to three times.

The results of the FET technology are considerable increases in the throughput rate and greater cost effectiveness of the compounding plant. Both effects are increased further by optimizations of the screw geometry in the feeding area depending on the product.

The FET equipment can not only be retrofitted to the ZSK twin screw extruder. It can be used with the same throughput increasing result in the ZS-B twin screw side feeder. This allows low bulk densitiy products to be fed into the extruder reliably in large quantities downstream.
