騰旋表面施膠系統(tǒng)/表膠淀粉連續(xù)制備系統(tǒng)是以天然淀粉為原料，經(jīng)過α-淀粉酶轉(zhuǎn)化，使長分子鏈淀粉轉(zhuǎn)化為短分子鏈降解淀粉。經(jīng)過降解后的淀粉適用于表面施膠，以達到增加紙頁的強度性能的目的。This system is based on natural starch as raw material, through α-amylase conversion, so that long molecular pectin converted into short molecular chain degradation starch. The degraded starch is suitable for surface sizing to increase the strength of the paper
噸包原淀粉通過起重設備吊入卸料料斗，料斗內(nèi)淀粉由風送設備送入淀粉料倉，料倉內(nèi)的淀粉經(jīng)計量螺旋輸送機被連續(xù)輸送到分散槽，同時在分散槽加清水稀釋分散；
1.Tons of raw starch is lifted into the discharge hopper through the lifting equipment, and the starch in the hopper is sent to the starch bin/tank by the air conveying equipment. The starch in the bin/tank is continuously transported to the dispersion tank by the metering screw conveyor, and at the same time, water is added to the dispersion tank to dilute and disperse.
在淀粉分散槽添加淀粉粉末的同時，淀粉酶按比例加入到分散槽內(nèi)與淀粉進行充分混合。
2.When starch is added to the starch dispersion tank, amylase is added to the dispersion tank in proportion to the starch for full mixing.
分散后的淀粉液由螺桿泵送入過濾器去除雜質(zhì)，過濾后的淀粉溶液進入1#蒸汽噴射器加熱，經(jīng)過加熱后的淀粉溶液進入反應槽進行酶化反應。經(jīng)過一定時間的酶化反應后，由轉(zhuǎn)子泵送入2#蒸汽噴射器加熱，并在蛇形盤管箱內(nèi)糊化及高溫滅活，終止酶反應。糊化后的淀粉膠液經(jīng)汽水分離器后進入淀粉儲存槽，同時加清水稀釋至所需的濃度在儲存槽內(nèi)儲存。儲存槽膠液由送料泵送至紙機上料槽。同時加清水稀釋至所需的濃度在紙機上料槽，以供上料站系統(tǒng)使用。
3.The dispersed starch solution is sent to the filter by the screw pump to remove impurities, and the filtered starch solution is heated into the 1# steam injector, and the heated starch solution enters the reaction tank for enzymatic reaction.
After a certain period of enzymatic reaction, the rotor pump is sent to the 2# steam injector for heating, and the gelatinization and high temperature inactivation in the serpentine coil box to terminate the enzymatic reaction. After gelatinized starch glue through the steam separator into the starch storage tank, at the same time add water dilution to the required concentration in the storage tank. The storage tank glue is fed by the feed pump to the feeding tank of the paper machine. At the same time, dilute the water to the required concentration in the paper machine feeding tank for the feeding station system.
