Benefits of beet pulp pellets
Like so many other by-products, the by-product of the sugar beet processing is no longer a waste but a real source of revenue increase. The pulp is often dried and pelletized for the production of high added value animal feed. If required, the beet pulp is enriched with molasses to boost the protein content of the product. The pelletized product is easy to store and transport ideal for the global animal feed market.
Dried product is normally pelletized in 6 to 16mm diameter pellets which allows to densify a product from 300 kg/m3 wet to 700kg/m3 dry.
Benefits of bagasse valorization
Even though bagasse is often used in a sugar can factory to produce the required steam at site, the factory usually have a surplus free bagasse which can be transformed into a value added by-product by drying possibly pelletized for different proposed.
The moisture content of bagasse can be reduced from 55% to 45% thanks to a belt pre drier recovering waste heat from the process. The pre-drying of bagasse allows to increase the heating value of the boiler fuel, increase the capacity of the boiler and at the same time reduce the risk of fouling effect on the tubes.
Furthermore, dried bagasse can also be pelletized and exported to e.g. the EU where it can be sold as a valuable biomass pellet for domestic or industrial us.
Finally, dried bagasse can also be enriched with molasses to produce a protein enriched animal feed product.
