Abstract (en)

To prepare a material of vegetable matter using at least one cereal plant, the upper parts of the plants are chopped into fragments, or a substantial fraction of the upper parts. The fragments are crushed or sheared into granules of 0.01-10.0 mm. The moisture content of the granules is set to a level of 10-35%, and the granules are used for the material. The granules are dried to give a residual moisture content of 5-20% before crushing or shearing. After the water content of the granules has been adjusted, they are extruded into the required material. The granule size in the composition is preferably where 5-50% are ≤ 0.25 mm, 5-40% are 0.25-0.5 mm, 15-60% are 0.5-1.0 mm, 1-10% are 1.0-1,25 mm, 0.5-7.0% are 1.25-1.4 mm, 1-10% are 1.4-1.7 mm, 0.1-10.0% are 1.7-2.36 mm, 0-10% are ≥ 2.36 mm. The cereal plants are maize or wheat. The cereal plants are chopped into fragments with a length of 0.5-10.0 cm. The material can be injected into a mold. Independent claims is included for: (a) cereal plant granules which, in dry weight, contain 20-60 wt% starch, 3-20 wt% proteins, 15-60 wt% cellulose and hemicellulose and lignin, 1-15 wt% lipids and 0.01-10.0 wt% sugar; and (b) a material with a vegetable base with a tensile strength of at least 10 N/mm<2> and a bending module of at least 1500 N/mm<2>. Preferred Features: The material has a bending resistance of at least 20 N/mm<2> and a bending module of at least 1500 N/mm<2>. The material is hollow, solid or profiled.

Abstract (fr)

Ce matériau peut être préparé par un procédé comprenant le découpage en fragments des parties aériennes de la plante, le broyage ou le cisaillement des fragments jusqu'à l'obtention de granulats, l'ajustement de la teneur en eau des granulats et la mise en forme du matériau. <IMAGE>
