Pulper

This stage is designed and carried out with special care as it is essential to carry out good grinding to ensure optimal operation of the entire line and excellent final product quality.

This processing cycle consists of robust and easy-to-maintain machines capable of processing difficult materials with high contamination rates, and the composition of the line depends on the type of input material.

Our systems are customized and can include water or dry prewashing and cold or hot washing, depending on the type and quality of the incoming material. In this way, we are able to ensure greater energy efficiency and minimize water consumption.
Our innovative hot washing system self-generates heat and does not require heating systems with associated electrical costs and maintenance problems. It is, moreover, capable of removing all kinds of impurities, odors, and printing inks, which is essential for obtaining the highest quality granule.

The machinery present at this stage of processing is designed with extreme care in order to remove most of the water content left in the product, reaching a moisture content of less than 1 percent. In this way, we are able to minimize subsequent energy and operational costs during the granulation phrase.

Thanks to the very low moisture content, we are also able to perform excellent homogenization and granulation through single- or twin-screw systems that can achieve up to 4 degassings.
