Description
A clean and cheap way of extracting soluble compounds from biomass is hot water treatment. Current facilities for this purpose are reactors composed of a tube filled with biomass pellets and crossed by a water flow. One of its main problems is loading and unloading the solid material once the extraction is completed. Wet biomass swells and becomes compacted, so its removal is impossible without stopping and opening the system. For that reason, we have developed a multibed system which facilitates this operation without stopping the plant, waiting for it to cool down nor dismantling it when loading and unloading. This system also allows to collect all exhausted solids, a critical operation within the process. This pilot plant is composed of 5 reactors, each one working together with the others or individually, isolated from the system.Other information

Advantages:
This plant includes a system which allows to collect all exhausted solids, a critical operation within the regular process. Nowadays there is no other industrial technology ready to extract hemicellulose nor its monomers in subcritical water, using only water as solvent. This pilot plant's main process considerably improves biomass extraction and fractionation in subcritical water. Therefore, its use can be considered within different sectors, such as wine, coffee and biopolymer production industries.
