Embodiment 1

[0018] The corn stalk cotton manufacturing process of present embodiment, its technological process is:

[0019] Corn stalk husk separation → straw drying → straw crushing → fiber separation → steam treatment.

[0020] Specific steps include:

[0021] 1. Separation of corn stalks and husks: send the corn stalks to the husk separator to separate the husks and obtain the husks.

[0022] 2. Straw drying: use a dryer to dry the separated straw, the drying temperature is controlled at 75°C, the drying time is 1.5 minutes, and the moisture content of the straw after drying is 1.8%.

[0023] 3. Crushing of straw: the dried straw is crushed with a knife mill, and the crushing time is 16 minutes, so that the parenchyma in the straw is completely separated from the vascular tissue scattered therein.

[0024] 4. Fiber separation: After being pulverized by a pulverizer, the parenchyma in the straw has been completely separated from the vascular tissue. Since the proportion of the vascul...

Embodiment 2

[0028] The corn stalk cotton manufacturing process of present embodiment, its technological process is:

[0029] Corn stalk husk separation → straw drying → straw crushing → fiber separation → steam treatment.

[0030] Specific steps include:

[0031] 1. Separation of corn stalks and husks: send the corn stalks to the husk separator to separate the husks and obtain the husks.

[0032] 2. Drying of straw: the straw is dried by natural air drying, and the moisture content of the straw after drying is 1.6%.

[0033] 3. Straw crushing: The dried straw is crushed by a knife crusher. The production capacity of the equipment is 1t / h, the diameter of the equipment is 1.6 meters, and the height is 4 meters. The columnar tower is equipped with a 750-watt ordinary motor and a crescent-shaped scimitar. Run for 20 minutes to completely separate the parenchyma in the straw from the vascular tissue scattered therein.

[0034] 4. Fiber separation: After being pulverized by a pulverizer, th...

Abstract

The invention relates to a manufacturing technology for corn straw cotton and belongs to the technical field of plant straw deep processing technology. The manufacturing technology for the corn straw cotton is characterized by comprising technology procedures of separating skin and stalk of the corn straw, drying the straw stalk, smashing the straw stalk, separating fibres, and vapour treatment. The manufacturing technology for the corn straw cotton has the advantages of being little in device investment, enabling a device to be simple in operation, saving energy, enabling the manufactured corn straw cotton to be low in cost and wide in application and the like, and can be used for producing baby diapers, sanitary pads, cigarette filters, buffering package materials, disposable lunch boxes, paper glasses and the like, and has the advantages of being environmental-friendly and changing waste into valuable.

Description

technical field [0001] The invention relates to a corn stalk cotton manufacturing process, which belongs to the technical field of plant stalk deep processing technology. Background technique [0002] Corn is one of the most widely distributed crops in the world. my country's corn planting area and total output rank second in the world. With the high yield of corn, the output of corn stalks is also quite large, with an annual output of 220 million tons. There are a lot of corn stalks in rural areas, and people haven’t fully utilized them for several years. In the past, straws were mainly used as livestock feed, living fuel or accumulated manure. At the turn of autumn and winter, corn stalks are often burned to pollute the air. This kind of treatment The method is also a waste of resources. [0003] In fact, corn stalks are also an important production resource for industrial and agricultural production. How to make full use of this rich straw resource has become an import...
