TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Process: The matrix is cleaned, by means of brushes, during the addition of the pressed good mat on a band tray into the press area and the pressed good mat is laid during the removal of the band tray on the matrix in the press area. The biomass is provided into the press area by means of a spreading trunk on the priorly cleaned matrix. The pressed good mat is precompressed after the spreading. The mat from the pressed good is adjusted before or after the compression by means of suitable agents regarding the processing parameters such as humidity and temperature and the moisture and temperature is adjusted by streaming with vapor or with vapor-air-mixture. The mat is heated with microwave for the adjustment of the temperature. The pressed good is adjusted, in the parameters temperature and moisture, before addition into the spreading trunk by means of suitable agents. The parameters of temperature and moisture are adjusted by providing vapor, vapor-air mixture or hot air. The temperature is adjusted by heating with microwave, preferably at 50-140degreesC. The matrix is fed with a quantity of about 50-2000 g/m2. The biomass is added with starch before the introduction into the matrix. The matrix and/or the sink plunger are heated by means of suitable heating medium at 60-240degreesC, preferably 80-110degreesC. The matrix has a layer thickness of 0.5-50 mm, preferably one millimeter and a bulk density of 20-800 kg/m3. The pressed good is subjected with a specific pressure, when closed in the press, of 10-150 N/mm2, preferably 20-40 N/mm2. The biomass is crushed into smaller grain size by means of machining, grinding, Masonite (RTM:)-process or a refiner process.Preferred Components: In the plant, a conditioning mechanism is inserted between the prepress and the fixed press. The arranged matrix has a channel length of the openings of 1:3 to 1:15 of the diameter of the wood-based fuel. The openings are conically, narrowing or cylindrically arranged in the matrix. The matrix is formed from steel and the openings are hardened. The pressing bar is provided with small tappets, which are submerged in the openings. A cleaning perforate plate is arranged at the pressing bar, which cleans through vertical shift of the tappet after a pressing mechanism. The pressing bar has vapor drillings for cleaning or for vaporizing the pressed goods. The arrangement of the pressing bar is even.
