Design of SSF Reactor Details

This factory will implement Simultaneous Saccharification and Fermentation (SSF) technology, which allows the process of changing sugarcane pulp into bioethanol carried out simultaneously. By using the SSF method, the sacrifice process (changing carbohydrates into sugar) and fermentation (converting sugar into ethanol) can be done in one stage, which can significantly increase efficiency and produce more optimal final products.

The SSF technique also allows the use of more efficient microbes, as well as reducing the risk of contamination of other microorganisms that can affect fermentation results. Therefore, with the application of this technology, it is expected that the factory can operate optimally and produce bioethanol with good quality.
