Embodiment Construction

[0035] In the following specification, all the same, similar or analogous elements and components will be denoted by the same reference numerals.

[0036] The terms "longitudinal", "vertical" and "transverse" are used with respect to the three dimensions (trihedron) L, V, T illustrated on the figures.

[0037] The upstream-downstream orientation will also be used for the longitudinal flow of common indoor plant material, from right to left, referring to the accompanying drawings, along the L axis.

[0038] The apparatus 10 schematically illustrated in FIG. 1 comprises a pretreatment chamber 12 which is of the general shape of a longitudinally oriented and substantially horizontal parallelepipedal chamber, for example with the direction shown in FIG. 1 from downstream to upstream. slight inclination.

[0039] The pretreatment chamber 12 is sealed to prevent any acid vapor from escaping into the atmosphere when acid is used in the process of the present invention.

Abstract

The invention proposes a method for pretreating plant starting material for the purpose of producing bioethanol and / or sugar by means of a common chamber (12), characterized in that: -during one period, the plant material (MP), introduced into the common pretreatment chamber, is a lignocellulosic plant starting material, the pretreatment of which is aimed at separating the cellulose, the hemicelluloses and the lignins so as to obtain a pretreated plant material that canbe hydrolysed and fermented for the production of bioethanol; -during another period, the plant material (MP), introduced into the common pretreatment chamber, is a sacchariferous plant starting material, the pretreatment of which is aimed at extracting therefrom, by diffusion, a sugar juice for the production of sugar and / or of bioethanol.

Description

technical field [0001] The present invention relates to the utilization of biomass, in particular to the non-dietary use of agricultural products. The invention particularly relates to the production of bioethanol from plant material. Background technique [0002] The production of agricultural plants in forms other than food that can actually be directly consumed by humans or animals requires large industrial investments, especially for the production of plants for the conversion of plant starting materials. [0003] Therefore, for the production of sugar from sugar containing resources such as sugar beet or sugar cane, a sugar refinery is required, the actual annual usage of which is 2400-3600 hours / year depending on the plant starting materials used. [0004] Outside these production time periods (which correspond to the agricultural production time periods of the target plant starting material), the device is not used. [0005] Many production methods have been optimiz...
