剑麻叶片加工工艺升级及副产物高值化利用效益评估

Benefit Evaluation of High Value Utilization of Upgraded Sisal Leaf Processing Technology and by Products

摘要: 剑麻是全球重要的硬质纤维作物之一。为降低剑麻加工成本，提升产业的经济及生态效益，推广节本增效的纤维加工工艺并对麻渣等副产物开展高值化利用势在必行。本文针对新型先压后刮式刮麻机及副产物加工工艺与配套设备在产业中的效益作评估。与传统的“先刮后压”式加工工艺相比，新研制的“先压后刮”加工工艺及其配套设备人均加工效率为0.56t/人•h，节约用水量33.33%，长纤维含杂率下降85%，加工1吨剑麻长纤维延伸的副产物高值化利用利润比主产品(长纤维)利润高70%。高值化利用工艺及设备提升了剑麻的纤维质量和生产效率，降低生产成本，提高了经济和生态效益。

Abstract: Sisal is one of the most important hard fiber crops. In order to reduce the cost of sisal fiber processing process and improve the benefits of economic and ecological of the industry, optimize processing technology of fiber processing and carry out high-value utilization of the by-products such as sisal residue is imperative. This paper evaluates the new type of processing technology from the production benefit and the utilization of by-products. The result shows that compared with the traditional processing technology, the processing efficiency of the advanced processing technology is 0.56 t/h, save the water consumption by 33.33%, and the impurity rate of long fiber decreases by 85%. The profit of sisal by-product of 1t long fiber processing is higher than that of the main product (long fiber) by 70%. The new technology and equipment improve the efficiency processing and quality of fiber, reduce the production cost, and improve the economic and ecological benefits.
