2.5.2 Briquetting
Briquettes (Fig. 2.12) are produced by compressing chopped straw into a cylindrical
form through a briquetting press shown in Fig. 2.13. The hydraulic operation pressure of the briquetting press (Muetek MPP 130) is set to 15 MPa and the press
works in three stages. First, the feedstock passes through the pre-compression unit,
which presses it inside the pressing block in a Y-direction. When a resistance of
