摘要： The invention provides a process and apparatus for the treatment and recovery of fibreboard and particle board waste. Waste fibreboard and particle board is fed into a steam chamber (8) and steam treated with steam under pressure from a steam generator (24). When the steam treatment is completed any effluent and excess steam are evacuated from the chamber (8) and the steam treated waste is passed through a rotating trommel (12). Woodfibres and woodchips pass through the screens (17) of the trommel (12) and are collected for drying and further processing. Waste material, such as melamine coatings, passes through the trommel (12) for collection and disposal. The collected woodfibres and woodchips can be processed for reuse in paper, cardboard or particle board manufacture or as mulch and other ground cover material.

摘要： A continuous-flow steam explosion reactor for pretreatment of organic material for further processing to value-added products is provided. The reactor comprises a loading section, a high-pressure retention section with an adjustable-speed conveyor, a pressure relief section and a discharge section. The reactor comprises means for providing steam into at least said high-pressure retention section and means for providing pressurized gas (e.g. air) to further boost pressure. The loading section is suitably configured to transfer material from ambient pressure to the high-pressure retention section while retaining high pressure and temperature in the high-pressure retention section, and the pressure relief section configured to transfer material from the high-pressure retention section to a discharge section while retaining high pressure in the high-pressure retention section. The pressure relief section is configured to release material with a drop in pressure to said discharge section while retaining high pressure in the high-pressure retention section.
