The prototype processing line includes a multi-vat boiler, mechanical cleaner, and hybrid dryer. The multi-vat boiler is equipped with a firebox that can burn many types of dry forest or agricultural waste, and is designed to heat three 20-L vats simultaneously for boiling degutted sea cucumber. The mechanical cleaner removes the spicule layer in a rapid and thorough manner to produce a clean product. The hybrid dryer can be heated by a firebox or by solar radiation; a biomass stove is used to burn waste wood to heat the dryer.
