摘要:
在实验室进行了高速离心分离净制熔解松脂液试验,考察了离心转速、分离因数、离心分离时间、脂液含油率和含水率对熔解脂液净制效果的影响,并与工厂高速离心分离扩试净制松脂液效果进行了对比分析。结果表明,熔解松脂液的实验室高速离心分离工艺条件为:脂液温度70~100℃,含油率40%~50%,离心速度4 000 r/min,分离因数2 862,离心时间20 min,净制松脂液的罗维邦色号为黄30、红0.7。松脂液高速离心分离工厂扩大试验的工艺条件为:脂液温度80~90℃,含油率40%,采用GQ105高速管式离心机,离心机转鼓内径105 mm,转速16 000 r/min,分离因数15 000,转鼓容积6.0 L,蠕动泵自动进出料,进料量200 mL/min,物料在离心管内停留时间1.2 min。扩大试验净制熔解松脂液固含量由1.9% 减少至0.1%以下,纳米级浊度由341.3 kcps下降至28.7 kcps,超细颗粒得到了很好的分离,脂液罗维邦色级黄色从35~45降至20~30,红色从3.1~5.0降至1.0~1.8。试验表明,采用高速离心分离技术净制干法熔解松脂液技术是可行的,高速离心分离技术可以在松脂加工企业推广应用。
Abstract:
In this study, the effect of several factors, including centrifugal time, separation factor, the content of oil and the content of the water, of the high speed centrifugal separation method on the cleansing of oleoresin at laboratory scale was analyzed and compared with the effects of the high speed separation on the oleoresin liquid at industrial scale. The optimum conditions of the cleansing process of the oleoresin liquid at laboratory scale by high speed centrifugal separation was as follows: temperature of the oleoresin liquid was 70-100℃, oil contents were from 40% to 50%, the centrifugal speed was 4 000 r/min, separation factor was 2 862, and centrifugation time was 20 min. The Luoweibang color of the resulting oleoresin liquid was as follows: the number of yellow color was 30, and the number of red color was 0.7. The optimum conditions of high speed centrifugal separation of the oleoresin liquid at industrial scale were: the temperature was 80-90℃, the oil content was 40%, by using GQ105 high-speed centrifuge tube, the diameter of the centrifuge drum was 105 mm, speed was 16 000 r/min, separation factor was 15 000, drum volume was 6.0 L, the feed volume was 200 mL/min by using peristaltic pump, and the residence time of the feed material in the centrifuge tube was 1.2 min. Compared with the high speed centrifugal method at laboratory scale, the solid content of the oleoresin liquid separated at industrial scale decreased from 1.9% to 0.1%, and the nanometer turbidity decreased from 341.3 kcps to 28.7 kcps due to the well separation of ultrafine particles. The number of the Luoweibang color of the oleoresin liquid decreased significantly. The number of yellow decreased from 35-45 to 20-30, and the number of red decreased from 3.1-5.0 to 1.0-1.8.
