Multi-stage straw organic matter extraction method
An extraction method and technology of organic matter, applied in the directions of organic fertilizer, biological organic part treatment, textile and papermaking, etc., can solve the problems of affecting the final fiber quality, low yield of the post-process, and pulp pulverization, etc., so as to facilitate the softening of fibers. , reduce fiber breakage or breakage, and promote the effect of separation

Embodiment 1
[0061] S1. Grass cutting: cut the straw into broken grass;
[0062] S2. Grass washing, infiltration and dehydration: the broken grass is washed with water and then dehydrated after absorbing water and swelling. After dehydration, the moisture content of the forage is about 80%;
[0063] S3. One-stage organic matter rubbing and extruding extraction: the dehydrated forage is sent to the first-stage rubbing machine for extrusion and rubbing. The feed direction is configured as 32%, 28%, and 25% in turn, and the organic matter is separated to separate part of the straw skin and fiber bundles (but not into powder), and at the same time, the organic matter is extracted and collected by the organic liquid;
[0064] S4. Spiral crushing reaction conveying: After the first stage of kneading, the crude fiber forage has a moisture content of about 65%, and the addition rate of 1.5kg / ton is added with biological enzymes, and then sent to the crushing screw reaction conveyor for crude fiber...
Embodiment 2
[0068] S1. Grass cutting: cut the straw into broken grass;
[0069] S2. Grass washing, infiltration and dehydration: the broken grass is washed with water and then dehydrated after absorbing water and swelling. After dehydration, the moisture content of the forage is about 80%;
[0070] S3. One-stage organic matter rubbing and extruding extraction: the dehydrated forage is sent to the first-stage rubbing machine for extrusion and rubbing. The feeding direction is configured as 30%, 27.5%, and 25% in turn, and the organic matter is separated to separate part of the straw skin and fiber bundles (but not into powder), and at the same time, the organic matter is extracted and collected by the organic liquid;
[0071] S4. Spiral crushing reaction conveying: After the crude fiber forage has been kneaded by the first stage, its water content is about 60%, and the biological enzyme is added at a rate of 1kg / ton, and then sent to the crushing screw reaction conveyor for crude fiber forag...
Embodiment 3
[0075] S1. Grass cutting: cut the straw into broken grass;
[0076] S2. Grass washing, infiltration and dehydration: the broken grass is washed with water and then dehydrated after absorbing water and swelling. After dehydration, the moisture content of the forage is about 80%;
[0077] S3. One-stage organic matter rubbing and extrusion extraction: the forage after dehydration is sent to the first-stage rubbing machine for extrusion and rubbing. The feeding direction is configured as 35%, 30%, and 25% in turn, and the organic matter is separated to separate part of the straw skin and fiber bundles (but not into powder), and at the same time, the organic matter is extracted and collected by the organic liquid;
[0078] S4. Spiral crushing reaction conveying: After the crude fiber forage has been kneaded by the first stage, its water content is about 65%, and the biological enzyme is added according to the addition rate of 2kg / ton, and then sent to the crushing screw reaction co...
