Problems solved by technology

[0007] 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

[0047] A fiber raw material, wherein, the fiber raw material is corn stalk husk; the corn stalk husk includes strip-shaped straw husk and straw skin shreds; the strip-shaped straw husk remains with pulp; the The residual amount of pulp on the strip-shaped straw skin is 0.5%.

[0048] The content of the strip-shaped straw skin is 33.3wt%, and the content of the straw skin shreds is 66.7wt%.

[0049] Above-mentioned fiber raw material adopts following process route to obtain:

[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.

[0051] see figure 1 and figure 2 , the agricultural harvester that the present embodiment adopts comprises chassis 4, power unit, electric device, hydraulic system, driver's cab 5, harvests the stalk harvesting table 1 of corn...

Embodiment 2

[0063] A fiber raw material, wherein, the fiber raw material is corn stalk husk; the corn stalk husk includes strip-shaped straw husk and straw skin shreds; the strip-shaped straw husk remains with pulp; the The residual amount of pulp on the strip-shaped straw skin was 2.5%.

[0064] The content of the strip-shaped straw skin is 55wt%, and the content of the straw skin shreds is 50wt%.

[0065] Above-mentioned fiber raw material adopts following process route to obtain:

[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 further adds a straw husk dispersion device 6 and an anti-blocking device 7, see image 3 , its operation process is the same as embodiment...

Embodiment 3

[0072] A fiber raw material, wherein, the fiber raw material is corn stalk husk; the corn stalk husk includes strip-shaped straw husk and straw skin shreds; the strip-shaped straw husk remains with pulp; the The residual amount of pulp on the strip-shaped straw skin was 3%.

[0073] The content of the strip-shaped straw skin is 45wt%, and the content of the straw skin shreds is 55wt%.

[0074] Above-mentioned fibrous straw raw material adopts following process route to obtain:

[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] In this embodiment, the rotational speed of the axial flow drum 11 is 980 r / min.

Abstract

The invention relates to a fiber raw material. The fiber raw material is corn stalk skins; the corn stalk skins comprise strip-shaped stalk skins and stalk skin silks; pulps remain on the strip-shaped stalk skins; the remaining quantity of the pulps on the strip-shaped stalk skins is not higher than 5%, preferably not higher than 3% and more preferably not higher than 0.5-2.5%. Through the adoption of the fiber raw material provided by the invention, the storage and transportation problems are preferably solved, the use performance is improved, the application field is expanded, the utilization value is enhanced, and the fiber raw materials can be purchased in bulk and can be industrially utilized on a large scale.

Description

technical field [0001] The invention relates to a plant straw fiber raw material, in particular to a processed fiber 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...
