Problems solved by technology

Biological degumming mainly includes microbial degumming and enzymatic degumming, but at present, the conditions for microbial degumming or enzymatic degumming are harsh, professional, and require high technical requirements for operators, and the microorganisms themselves and their metabolites will also increase the COD of production wastewater, and the production cost high

Embodiment 1

[0014] Embodiment 1 Raw ramie is 100kg of fresh ramie just peeled off by a hemp peeling machine, and the filler is 100kg of residual hemp bone and hemp leaves after peeling off the hemp. The raw ramie and filler are stored in a cool place, and the raw ramie The total moisture content of the filler and the filling is 60%. Mix 0.01 kg of white sugar into the raw ramie hemp and stir evenly; tie the raw ramie hemp into a handle with a length of 30-50 cm, put it in a round baler and beat it together with the filler. Bundle, so that the filler wraps the raw ramie; wrap the round bundle of ramie with plastic stretch film on the wrapping machine for 2 layers and seal it, and store it in a cool and dry place for 180 days; unpack the silaged ramie, The ensiled ramie is taken out, washed with clear water by a hemp washing machine, then dried and oiled. Ramie degumming reaches 8 in the present embodiment + , the fiber strength is 75%, the obtained product fibers are basically dispersed, ...

Embodiment 2

[0015] Example 2 The difference from Example 1 is that the filler is 400 kg of hemp bone and hemp leaves remaining after peeling off the hemp, and the total moisture content of the raw ramie and the filler is 65%, and 1 kg of white sugar is mixed into the raw ramie , the number of coating layers is 3 layers, and the storage time in a cool and dry place is 120 days. Ramie degumming reaches 9 in the present embodiment + , the fiber strength is 78%, the obtained product fibers are basically dispersed, and the product yield is 70%.

Embodiment 3

[0016] Embodiment 3 Different from Example 1, the filler is 900kg of residual hemp bone and hemp leaves after peeling off the hemp, and the total moisture content of the raw ramie and the filler is 70%, and 2kg of white sugar is mixed in the raw ramie, The number of coating layers is 4 layers, and the storage time in a cool and dry place is 60 days. Ramie degumming reaches 9 in the present embodiment + , the fiber strength is 80%, the obtained product fibers are basically dispersed, and the product yield is 72%.

Abstract

The invention discloses a biological degumming process for ramie. According to the process, the degumming is carried out on raw ramie after the ramie is stripped, and the process specifically comprises the steps of material preparing, bundling, ensiling, ramie washing, oil feeding and the like. According to the biological degumming process for the ramie, disclosed by the invention, microorganisms attached to the ensiled ramie are utilized to degrade a major part of colloid, and simultaneously, the ensiling is carried out in a sealed anoxic environment; lactic acid, acetic acid and other organic acids are gradually accumulated to further degrade the colloid and inhabit the growth of spoilage organisms, so that the ramie can not rot, thereby ensuring the strength of ramie fibers while ensuring the effective degumming. Therefore, the process is simple, the operation is convenient, the energy consumption is low, the pollution is light, the implement is easy, the requirement on instrument is small and the cost is low, and the process can be used for on-site degumming of the ramie in a producing area, thereby saving the transportation cost.

Description

technical field [0001] The invention relates to the field of ramie degumming, in particular to a ramie biological degumming process. Background technique [0002] Silage is a technology in the field of green fodder storage. Silage is made of freshly harvested crop products (corn for feed), by-products (corn stalks, wheat straw, sweet potato seedlings), and pasture (alfalfa) that contain a certain amount of sugar. The raw materials are cut into lengths of 2 to 4 centimeters, those with more water and soft texture can be slightly longer, and those with less water and hard texture can be slightly shorter. Various raw materials can be mixed and prepared, preferably with a moisture content of 55% to 70%. Mixed ingredients are tightly packed into silos / silos, special plastic bags or permanent silos and sealed. Mature silage is green to dark green in color, soft and moist in texture, and can be stored for about a year. Generally, silage is fermented with the help of natural lac...
