The configuration of a washing line for TETRAPAK can be very different depending on the level of contamination of the material to recover. We stand out for our ability to design and devise customised lines.

TETRAPAK washing lines are divided into several stages, depending on the characteristics of the input material. In general, the lines designed by Recy Technologies are divided into several main stages:

Sorting and grinding

This stage is designed and carried out with special care as it is essential to sort, either manually or automatically, and grind materials accurately. This ensures an excellent operation of the line and high-quality final product.

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 machinery depends on the type of input material.

Pre-washing and washing

Our lines are customised and can include either a water or a dry prewashing and either a cold or a hot washing, depending on the type and quality of the input material. This way, we guarantee an excellent sorting and washing of the material, and, at the same time, energy efficiency and low water consumption.

Unlike conventional systems that wash cold, our innovative washing line washes hot. Moreover, it self-generates heat and does not require any heating systems for water and steam production, with associated electrical costs and maintenance issues. It is also capable of removing all kinds of impurities and printing inks, which is essential to obtain a high-quality granule. In addition, we are deeply proud of our ability to obtain an odourless ground and/or granule without the use of extra chemical additives.

Drying and granulation

At this stage of processing, the machines remove most of the water left in the product, reaching an amount of moisture inferior to 2%. This way, we are able to minimise energy and operational costs during the granulation phrase.

Due to the very low moisture content, we are able to perform excellent homogenisation and granulation through single-screw or twin-screw systems up to 4 degassings.
