  • Patent number: 5413746
    Abstract: A method for molding shaped products from particles of vegetable origin which have a size of 0.002 to 10 mm at a moisture content of 4 to 15%. The method includes the steps of mixing a filler containing particles of vegetable origin and a binder which is obtained from hemicelluloses released from particles of vegetable origin upon molding. The briquettes are formed from the resultant mixture with an axial passageway then packed and transferred to a molding zone where a continuous shaped blank is obtained by joining each successive packed briquette to the preceding one under a specific pressure of 2 to 50 MPa and a temperature in the range of 160.degree. to 350.degree. C. A counterpressure equal to at least the molding pressure is generated as each successive packed briquette is joined at the molded end of the continuous molded blank. Then products of required length are cut from the resultant continuous shaped blank. An apparatus for carrying out the method includes a chamber (4) for molding the briquettes.
