Problems solved by technology

[0008] However, the above-mentioned technology is only limited to extruding corn stalks for forage grass, which greatly limits its application range
And because the pulp is not removed when the above-mentioned kneading technology is used, the corn stalk with a silky structure obtained after processing contains all the pulp of the corn stalk, and because the pulp contains a certain amount of xylan hemicellulose, this type of semicellulose Under the action of light and oxygen, cellulose is easily oxidized to form carbonyl chromophore and carboxyl auxochrome, which will cause serious yellowing phenomenon when used in papermaking; The tear index of the paper is reduced to a certain extent

Embodiment 1

[0048] The moisture content of a raw material of corn stalks is 15%; the raw material of corn stalks at least includes separated husks, husks and leaves, wherein the husks include strip-shaped husks and straw skins, and the husks include separated The free husk outside the skin and the unpeeled bonded husk remaining on the skin; the mass percentage of water-soluble sugar in the straw skin shreds relative to the dry raw material is 10.0%; the straw skin shreds The crystallinity is 55%.

[0049] The above-mentioned corn stalk raw material for papermaking is obtained by the following process route:

[0050] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the skin, pulp and leaves, and then dried in the field until the moisture content was 15% and bundled.

[0064] The moisture content of a raw material of corn stalks is 15%; the raw material of corn stalks at least includes separated husks, husks and leaves, wherein the husks include strip-shaped husks and straw skins, and the husks include separated The free husk outside the skin and the unpeeled bonded husk remaining on the skin; the mass percentage of water-soluble sugar in the straw skin shreds relative to the absolute dry raw material is 17.5%; the straw skin shreds The crystallinity is 45%.

[0065] The above-mentioned corn stalk raw material for papermaking is obtained by the following process route:

[0066] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the skin, pulp and leaves, and then air-dried in the field until the moisture content was 45% and bundled.

[0067] On the basis of Embodiment 1, the agricultural harvester used in this embodiment furt...

Embodiment 3

[0073] The moisture content of a raw material of corn stalks is 15%; the raw material of corn stalks at least includes separated husks, husks and leaves, wherein the husks include strip-shaped husks and straw skins, and the husks include separated The free husk outside the skin and the unpeeled bonded husk remaining on the skin; the mass percentage of water-soluble sugar in the straw skin shreds relative to the dry raw material is 13.5%; the straw skin shreds The crystallinity is 48%.

[0074] The above-mentioned corn stalk raw material for papermaking is obtained by the following process route:

[0075] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the bark and leaves, and then air-dried in the field until the moisture content was 30% and bundled.

[0076] Described agricultural harvester is with embodiment 1.

[0077] The content of the skin is 30wt%, t...

Abstract

The invention relates to a maize straw raw material. The maize straw raw material is taken from maize straws harvested in a maize mature period. The maize straw raw material contains 15-45% of water. The maize straw raw material at least comprises skin, flesh and leaves which are separated. The skin comprises strip straw skin and straw skin threads. The flesh comprises free flesh deviated from the skin and combination flesh not peeled and retained on the skin. The straw skin threads contain 10.0-17.5% by mass of water-soluble sugar relative to absolute dry raw materials, and crystallinity of the straw skin threads is 45-55%. The maize straw raw material well resolves the problems of storage and transportation, improves use performance, expands application field, improves utilization value, is capable of being purchased in mass and achieves large-scale industrial utilization.

Description

technical field [0001] The invention relates to a corn stalk raw material, in particular to a processed corn stalk raw material. Background technique [0002] Corn is a crop that is mainly used as feed for grain, economics and fodder, and corn stalks are also an important production resource for industrial and agricultural production. As a resource, corn stover is rich in nutrients and available chemical components, and can be used as raw material for livestock feed. For a long time, corn stover has been one of the main roughage raw materials for livestock. [0003] As one of the three major food crops, corn has an annual output of about 250 million tons of by-product corn stalks, accounting for as much as 30% of the total crop stalks, ranking second only to the United States in the world. [0004] The yield of corn stalks is so abundant, but it has not been rationally and effectively utilized all the time. In the past, people used a small amount of straw as heating and c...
