In a process for producing bleached mechanical woodpulp, said process comprising the steps of

Method for producing bleached wood fibre material

The present invention relates to a container for holding bulk material, having a closable inlet for the bulk material in the upper closure of the container, a cross-sectional geometry narrowing in the outlet direction for the bulk material, an outlet tube for the bulk material arranged subsequently in the outlet direction, a first reversible mechanical closure device (A), which is arranged in the transition region from the container body to the outlet tube or in the outlet tube itself and, by opening, releases the bulk material from the interior of the container, and a second closure device (B) which reversibly closes the mouth of the outlet tube, the second closure device being a cover which is pressed flush onto the mouth of the outlet tube by means of a closure device, there being a seal which seals the outlet tube in a gas- and liquid-tight fashion from the external environment at least on the contact surface of the cover with the mouth degree of the outlet tube, wherein the cover is screwed onto or is pressed with a clamping ring or a bayonet closure onto the mouth of the outlet tube.

A method of producing cellulose from lignocellulosic material by sulfite digestion or sulfate digestion in the presence of a salt of dithionous acid comprises using the salt of dithionous acid in an amount from 0.1 to 4.0 wt. % based on the amount of oven-dry lignocellulosic material.

Use of sodium dithionite in pulping

The present invention relates to a process for the production of bleached wood particles and a process for the production of pale to white wood-base materials which are produced from the bleached wood particles.
