In addition to being rich in sugar and water, it also contains 28, which is very beneficial to human metabolism. Alkanol, amino acids, polyphenols, vitamin B6 and other nutrients as well as beneficial trace elements such as selenium, zinc, calcium, and iron. Among them, octacosanol is a world-recognized anti-fatigue functional substance, which can improve endurance and energy to the human body. Improve sensitivity and stress ability, improve myocardial function, increase the body's metabolic rate, lower blood lipids, enhance sexual function, etc. It can also be used to treat Parkinson's disease in the early stage of old age.

Description

一种蔗汁过膜前预处理系统及工艺 技术领域
本发明涉及甘蔗汁深加工技术领域，具体是一种纯甘蔗植物细胞水饮料生产线的蔗汁过膜前预处理系统及工艺。
背景技术
甘蔗是一种常见的水果，也是最重要的制糖原料，因为生长期长达12个月，其营养价值很高，除了含有丰富的糖分和水分，还含有对人体新陈代谢非常有益的二十八烷醇、氨基酸、多酚、维生素B6等营养以及硒、锌、钙、铁等有益微量元素，其中的二十八烷醇是世界公认的抗疲劳功能性物质，对人体具有增进耐力、精力，提高灵敏性及应激能力，改善心肌功能，提高机体新陈代谢的比率、降血脂、增强性功能等功效，还可用于治疗老年初期帕金森氏病。二十八烷醇对人体非常有益，科学家发现，甘蔗是含二十八烷醇最丰富的水果，二十八烷醇主要存在甘蔗皮上附着的蔗蜡中，而我们在日常吃甘蔗或喝常规榨汁机压榨出来的甘蔗汁时，由于无法充分撕解甘蔗皮或者直接舍弃甘蔗皮，因此是无法吃到甘蔗中金贵的二十八烷醇的。
目前我国产的甘蔗主要用来制糖，其制糖工艺主要包括压榨提汁、蔗汁清净、蔗汁蒸发、煮糖和干燥等多道工序，在压榨提汁工序中，需要先用撕解机将甘蔗连同甘蔗皮一起撕解破碎成丝状蔗料，使甘蔗的纤维组织撕裂，再将丝状蔗料依次经过多级压榨机进行充分压榨，其中第一、二级压榨机压榨出来的蔗汁用于制糖，其余后级压榨机压榨出来的蔗汁用来作为渗透汁往前跨级渗透蔗渣。第一级压榨机压榨出来的蔗汁称为甘蔗初压汁，其完全为甘蔗本身的鲜榨汁液，不包含有任何额外添加的物质，包括水，因此甘蔗初压汁完整保留了甘蔗中的对人体有益的各种营养成分，更重要的是，经过大型设备的撕解和压榨，甘蔗皮已被充分撕解为絮状，甘蔗皮中金贵的二十八烷醇会连同蔗蜡一起析出至甘蔗初压汁中，为此我们专门设计了一条纯甘蔗植物细胞水饮料生产线，利用糖厂的甘蔗初压汁来提取和配制纯甘蔗植物细胞水饮料，此饮料含有甘蔗中大部分对人体有益的物质，包括二十八烷醇在内，这样人们就能方便地吃到甘蔗中宝贵的营养成分。
我们设计的生产线采用三级膜过滤系统来对蔗汁进行分离过滤，由于甘蔗初压汁中含有大量的杂质，极易滋生细菌，所以在蔗汁过膜前，需要通过预处理系统去除初压汁中98％以上的杂质，同时抑制细菌生长，才能进入三级膜过滤系统进行分离过滤。如果对蔗汁过膜前的预处理不当，蔗汁不但容易产生无法消除的异味，而且无法提取到宝贵的二十八烷醇， 同时会使膜设备频繁堵塞，根本无法正常运行，因此蔗汁过膜前预处理系统在整条生产线中显得至关重要。

本发明的蔗汁过膜前预处理工艺包括以下步骤：
(1)、蔗汁提取及初步除杂
从糖厂第一级压榨机下方的蔗汁槽中抽取甘蔗初压汁，然后泵送至60-120目的筛滤装置中，由筛滤装置将甘蔗初压汁中的粗大蔗渣及泥沙过滤掉，得到的蔗汁滤液流入初压汁箱中存放并定时对沉积在初压汁箱箱底的蔗渣和泥沙进行排放，然后再将初压汁箱中的蔗汁送入下一步骤进行处理。进一步的，筛滤装置分离出的蔗渣及泥沙经滤渣回送装置送回糖厂回收利用；初压汁箱箱底排放的蔗渣和泥沙经排泥泵送回糖厂回收利用。
从糖厂提取的甘蔗初压汁有20-30％是蔗渣及泥沙，在本步骤中，初步除杂的筛滤装置可以有效滤掉蔗汁中的粗大蔗渣及泥沙，定时对沉积在初压汁箱箱底的蔗渣和泥沙进行排放是为了防止蔗渣和泥沙在初压汁箱箱底沉积时间久而发酵，以保证蔗汁新鲜度。经过本步骤的处理，甘蔗初压汁中90％以上的蔗渣及杂质已被除去。
(2)、蔗汁加热抑菌及去除浮杂
由上一步骤送来的蔗汁先送入加热器中进行一次加热，使蔗汁温度达到60-80℃，以杀灭或抑制蔗汁中的大部分微生物，防止蔗汁变质产生异味，然后再将蔗汁送入沉降器中进行物理沉降，在沉降处理过程中，蔗汁中的泡沫和浮渣从沉降器上部的浮渣溢流口排出并流入残汁桶中，蔗汁中密度较大的蔗渣和泥沙沉降至沉降器底部后从沉降器底部排出并流入残汁桶中，蔗汁除杂清汁从沉降器的清汁出口排出，并送入下一步骤进行处理。进一步的，残汁桶中收集到的杂质经残汁泵送回糖厂回收利用。
由于第(1)步骤送来的蔗汁为糖厂的鲜榨蔗汁，活性很强，极易变质，在本步骤中，必须马上将蔗汁加热到50-70℃，以杀灭或抑制蔗汁中的大部分微生物，防止蔗汁变质产生异味，影响后续产品的品质；加热抑菌后的蔗汁通过沉降器可进一步除掉蔗汁中所含的大部分浮渣和泥沙。
(3)、蔗汁除细末
由上一步骤送来的蔗汁送入除细末装置中进行纯物理方式的固液分离处理，以去除蔗汁中悬浮着的240目以下蔗渣细末，由除细末装置排出的蔗汁除末清汁送至除末清汁箱中存放， 然后再将除末清汁箱中的蔗汁送入下一步骤进行处理。进一步的，除细末装置收集到的蔗渣细末经排末泵送回糖回收利用。
经过第(1)、(2)步骤处理后的蔗汁中仍然悬浮有大量240目以下的蔗渣细末，在本步骤中，必须除去才能保证后续的膜过滤系统后级处理系统中膜设备的正常运行，为此需要进行除细末处理，而且处理需要采用纯物理方式，以避免影响蔗汁质量。
(4)、蔗汁过膜前的加热及除杂
由上一步骤送来的蔗汁先送入加热器中进行二次加热，使蔗汁温度达到85℃，以将蔗汁中的蔗蜡完全融解，使二十八烷醇从蔗蜡中分离出来并进入蔗汁中，然后再将加热后的蔗汁送入80目的滤袋过滤装置进行过滤，由滤袋过滤装置滤除蔗汁在二次加热过程中生成的凝聚物、水垢和碳垢杂质，从滤袋过滤装置出来的蔗汁流入微滤原料罐中存放，然后再将微滤原料罐中的蔗汁送至后级的三级膜过滤系统中进行膜处理。
蔗蜡的融解温度在76℃左右，为了充分融解蔗蜡，以提取到蔗蜡中宝贵的二十八烷醇，在本步骤中，需要将蔗汁进一步加热到85℃，使以将蔗汁中的蔗蜡完全融解，使二十八烷醇从蔗蜡中分离出来并进入蔗汁中，另外加热后的蔗汁粘度下降，也有利于后级的过膜，蔗蜡的分子量远大于二十八烷醇的分子量，在后级过膜时可通过膜去除蔗蜡，保留二十八烷醇。蔗汁在加热过程中，会生成的新的凝聚物、水垢和碳垢杂质，如果直接进入后级的膜处理系统，容易堵塞膜处理系统原配的前置过滤装置，影响膜过滤系统的正常运行，因此在进入膜处理系统前，还要设置一道滤袋过滤装置来滤除此类杂质。
上述图例仅为本发明的典型实施例，并不用于限制本发明，凡在本发明的精神和原则之内所作的任何修改或等同替换和改进等，均应包含在本发明的保护范围之内。

    (2)、蔗汁加热抑菌及去除浮杂
    由上一步骤送来的蔗汁先送入加热器中进行一次加热，使蔗汁温度达到60-80℃，以杀灭或抑制蔗汁中的大部分微生物，防止蔗汁变质产生异味，然后再将蔗汁送入沉降器中进行物理沉降，在沉降处理过程中，蔗汁中的泡沫和浮渣从沉降器上部的浮渣溢流口排出并流入残汁桶中，蔗汁中密度较大的蔗渣和泥沙沉降至沉降器底部后从沉降器底部排出并流入残汁桶中，蔗汁除杂清汁从沉降器的清汁出口排出，并送入下一步骤进行处理；

    (4)、蔗汁过膜前的加热及除杂
    由上一步骤送来的蔗汁先送入加热器中进行二次加热，使蔗汁温度达到85℃，以将蔗汁中的蔗蜡完全融解，使二十八烷醇从蔗蜡中分离出来并进入蔗汁中，然后再将加热后的蔗汁 送入80目的滤袋过滤装置进行过滤，由滤袋过滤装置滤除蔗汁在二次加热过程中生成的凝聚物、水垢和碳垢杂质，从滤袋过滤装置出来的蔗汁流入微滤原料罐中存放，然后再将微滤原料罐中的蔗汁送至后级的三级膜过滤系统中进行膜处理。
