    摘要: The present invention relates to a process for simultaneous colouring and U.V. stabilisation of polymers. The process comprises colouring and stabilising the polymer with dyed lignin.
    With this process different colour shades may be obtained ranging from light shades through to rich dark shades, depending on the concentration of dyed lignin. The polymers e.g. polyolefins obtained have a glossy finish.
    Further, the use of the dyed lignin as the pigment composition also gives the polymer that has been coloured a simultaneous enhancement of stability to U.V. radiation.

    摘要: A process for the production of elementary vegetable bast fibres is provided, which process comprises the steps of

    a) cutting raw vegetable bast fibres to a fibre length of 8 to 400 mm,
    b) chemically treating the cut fibres to remove lignin and pectin compounds,
    c) drying the fibres obtained in step b),
    d) mechanically opening the dried fibres using a mechanical opening device.

    The process allows the production of elementary, largely cellulosic vegetable bast fibres having the following chemical properties:

    a lignin content of 0 to 5%, a uronic acid content of 0 to 2.5%, a rhamnose content of 0 to 0.5%, based on the oven-dry weight of the fibres,
    and the following physical properties:
    a single elementary fibre tensile strength of 100 to 600 MPa and an elasticity modulus of 35 to 100 GPa.

    摘要: System for controlling the air composition within a storage room for breathing vegetable products. The storage room is connected to means for controlling the oxygen contents of the atmosphere in the storage room and comprises one or more sensors for sensing the air composition in the storage room. A processor is available receiving the sensor signals and supplying control signals to oxygen contents controlling means. Furthermore the storage room comprises sensors for determining the development of metabolites in the vegetable products at the transfer of normal breathing to fermentation. The processor based on the signals, delivered by said sensors, controls the oxygen contents controlling means such that the vegetable products are stored in an air composition in which the oxygen contents is as low as possible without fermentation occurring.

    摘要: The invention relates to a counter-current extraction process with which the starting material to be extracted is conveyed in an extruder through zones of high and low pressure. The zones of high and low pressure can, for example, be formed by different screw elements of opposing pitch. Extractant is fed in in the high pressure zones which are located upstream of the screw elements of opposing pitch. The extractant then flows in counter-current to a discharge opening which is located in or close to the low pressure zone, downstream of a screw element of opposing pitch. With the extraction method according to the present invention a stable counter-current extraction process can be obtained over a very short extraction length and a high extraction yield can be achieved within a short time by intensive mixing of the starting material with the extractant. Furthermore, high pressures can be used in the extraction apparatus according to the present invention since the discharge openings are located close to the low pressure zones. As a result the extraction yield is further increased and extraction fluids in supercritical state can be used.
