Description

一种全营养纯净粉糖和液体糖浆的工业化生产工艺及设备 技术领域
本发明涉及一种全营养纯净粉糖和液体糖浆的工业规模化生产工艺及设备，属于制糖工艺技术领域。
背景技术
甘蔗是一种一年生的茎类水果，其从生长到成熟期为一年，而其他水果的挂果时间一般仅以月计，再长都不足一年，挂果时间越长，其营养越丰富，所以，甘蔗所含营养的丰富是其他水果难以媲美的。甘蔗中除了含有丰富的糖分和水分外，还富含多种其他营养成分，包括多种氨基酸、二十八烷醇、多酚、钙、铁、锌、硒等，还含有维生素B1、B2、B6和维生素C等多种维生素。然而，甘蔗中这些对人体非常有益的丰富营养成分人们却几乎吃不到，因为上述的很多营养在蔗皮中，人们日常食用时往往是去皮食用，而在使用甘蔗进行工业化制糖时，甘蔗中的丰富营养成分虽然能够在对甘蔗撕解、压榨的工艺中被析出，但在工业化炼糖的以下四个环节中又被破坏并去除掉了：
1、炼糖用的蔗汁需要投入一些化学添加剂如石灰、磷酸、二氧化硫气体等辅料进行pH调节和澄清，这些添加剂会对上述营养成分造成破坏；
2、精炼糖还需对澄清的蔗汁进行脱色，尤其是精炼糖的脱色要求更高，如采用离子交换树脂塔或糖汁上浮工艺除去糖以外的有颜色的物质，而甘蔗中的很多营养成分是有色的，其会在脱色工艺中被去除；
3、炼糖过程要结晶，结晶过程随着糖分子的长大，其他元素都被排除在外；
4、炼糖过程要分蜜，把含有丰富营养成分的蜜排掉，以获取洁白的糖结晶体。
由此可见，从西方引进的大规模炼糖工艺虽然让我们吃到纯净洁白的糖，但却丢掉了甘蔗中众多宝贵的营养成分。
而中国传统的民间土法炼糖工艺虽然能保住甘蔗中的部分营养成分，但其榨汁工艺没 有撕解甘蔗的步骤，使得甘蔗皮中的稀缺宝贵营养成分如二十八烷醇等不能有效析出，而且部分土法炼糖的澄清工艺过程仍需加入石灰，会进一步对甘蔗汁中的营养成分造成破坏。另外因土法炼糖的过滤和澄清工艺和设备简陋，无法达到工业化生产的要求，所生产的糖含泥沙、蔗渣等杂质较多，口感不佳，含菌量高，甚至还可能会含有泥沙带来的土壤农药残留等有害物质，人们过多食用往往会对人体健康产生不利的影响。
申请号为CN201410235021.1的中国发明专利公开了一种黄金糖的生产工艺，其采用压榨→蔗糖汁→预过滤→微滤膜过滤→预浓缩→离子交换树脂脱色→浓缩→结晶→干燥等步骤，进而得到一种含有一定营养成分的不带蜜的黄金糖，该工艺方法虽然解决了上述第1个环节所产生的问题，但对于第2～4环节所产生的问题仍然无法有效解决，因此该黄金糖仍然是一种去掉了甘蔗大部分营养的糖。申请号为CN201410208178.5的中国发明专利公开了一种原生态红糖工厂化生产方法，其采用糖厂的甘蔗混合汁为原料，经加石灰乳调节pH值至5.8～6.6，筛滤，加热上浮去除浮渣，微滤去除杂质，蒸发浓缩得到锤度为60～65°Bx的糖浆，在125～130℃温度下，常压煮糖，得到浓度为95～98°Bx的糖浆，打砂，成型，实现工厂化生产原生态红糖。该工艺方法也采用添加石灰的环节，上浮去除浮渣工艺也需加入添加剂，且上浮除渣工艺仍会留有很多较长纤维无法去除，容易使微滤膜堵塞，无法工业化运行。另外，在这两个专利所述的生产工艺中，采用的澄清过滤工艺均为化学物理法，而且工厂压榨甘蔗一般采用多级压榨，第一级以后每级均需淋水给甘蔗渣，以便洗出剩余糖分，所得甘蔗汁为天然甘蔗汁与大量外加洗水的混合汁，外加洗水会对对最终制成的糖有一定污染。
发明内容
本发明的目的是提供一种全营养纯净粉糖和液体糖浆的工业化生产工艺，其创造性地采用三级物理过滤替代传统的化学物理过滤，首次实现了纯物理纯天然的工业化炼糖，同时甘蔗汁取自糖厂工业化压榨的一级初压汁，充分地获取了甘蔗的全部营养成分，但又不是目前工业化普遍采用的全汁提取，使糖及糖浆产品的物质100％来自甘蔗本身，解决了现有工业 化炼糖工艺丢失甘蔗大部分营养成分，而土法炼糖取不到部分宝贵成分且会掺入过多杂质的问题。
一种全营养纯净粉糖和液体糖浆的工业化生产工艺，包括以下步骤：
(1)、提取初级压榨甘蔗汁：利用糖厂常规压榨设备对甘蔗进行压榨，仅提取从第一级压榨机压榨出来的甘蔗汁。此甘蔗汁为含有甘蔗全部营养的纯甘蔗汁，但不含外加的洗水，每一滴来自甘蔗细胞，使得最终糖及糖浆产品中含的水为纯甘蔗植物水，更健康。
(2)、第一级物理过滤：结合糖厂压榨车间生产现场设计筛板，筛板安装在第一级压榨机的榨棍下，实现无动力消耗完成对步骤(1)所提取的甘蔗汁进行第一级物理过滤，所述筛板采用50～200目的筛网。经第一级物理过滤后，甘蔗汁中99％的泥沙和所有片状或粗长的甘蔗渣及杂质全部被滤除，但还有很多可见的细短蔗渣纤维及杂质。
在本步骤中，所述筛板也可以采用50～150目筛网的高频振筛进行替代，但使用高频振动筛则需要额外提供动力。
(3)、第二级物理过滤：采用专门设计的蔗末分离机对步骤(2)得到的甘蔗汁进行第二级物理过滤，所述蔗末分离机采用200～500目的滤网。经第二级物理过滤后，甘蔗汁中的细短蔗渣纤维及杂质被滤除，但仍有很多悬浮物，比较浑浊，不剔透。
(4)、第三级物理过滤：将步骤(3)得到的甘蔗汁加热到50～90℃，采用孔径为50～350nm的微滤膜对甘蔗汁进行第三级物理过滤。经第三级物理过滤后，甘蔗汁中的细菌、极微小的沙土和杂质被滤除，甘蔗汁变得剔透晶莹，极其洁净。
在本步骤中，所采用的微滤膜可选用陶瓷膜或有机高分子膜。
(5)、煮糖：利用常规煮糖工艺对经三级物理过滤后得到的甘蔗汁进行煮糖，当蒸发掉50～60％的水分时，即可获得包含全营养的纯净液体糖浆，该液体糖浆中所含的水分100％是甘蔗植物水；而当蒸发掉95％的水分时，即可获得包含全营养的纯净粉糖，该糖呈粉状，不呈大晶体状，入口即化。所述粉糖也可以进一步成型加工为片糖或糖块。
在上述步骤(3)中，由于甘蔗汁粘性大，使用常规的物理过滤设备过滤甘蔗汁中200～500目的细短蔗渣纤维时，筛网非常容易堵塞，设备无法连续生产运行，如仅滤去200目以下的蔗渣及杂质，则第三级物理过滤中的微滤膜堵塞严重，需要频繁清洗膜，每8小时清洗一次，每次洗2个多小时，不仅膜的投资及运行成本高，且无法实现工业化连续运行。为此我们专门设计了一款不易发生堵塞且运行稳定的蔗末分离机，该机可有效过滤甘蔗汁中200～500目细短蔗渣纤维，使第三极物理过滤实现2～3天清洗一次膜，大幅降低了第三级物理膜过滤的投资成本和运行成本,使该工艺可实现工业化。
所述蔗末分离机包括外壳和机架，外壳横向设置在机架上，外壳内依次设有入料仓、分离仓和出料仓，入料仓上方设有入料口，分离仓和出料仓的下方分别设有出汁口和出渣口，分离仓内设有一个横向布置的滤网筒，滤网筒的入口和出口分别和入料仓和出料仓相连通，滤网筒内部设有螺旋桨叶组件，螺旋桨叶组件由减速电机驱动，螺旋桨叶组件由纵向搅拌叶片和螺旋叶片组合而成，减速电机通过转轴带动纵向搅拌叶片和螺旋叶片实现转动。本机工作时甘蔗汁从入料口注入后通过快速旋转的螺旋桨叶组件形成离心射流，射流连续强力冲向滤网筒，冲出滤网筒的为滤出液，滤出液从出汁口流出；蔗末及杂质被螺旋桨叶组件从滤网筒内侧刮下并挤压输送从出渣口排出。本机既能实现汁渣分离的功能，同时又能利用离心射流冲击和螺旋叶片环刮功能来清除滤网筒内侧的蔗渣，有效防止堵塞，还能实现螺旋输送排渣的功能。
本发明的生产工艺将中西方炼糖理念结合，摒弃脱色、结晶工艺，工艺路线比常规炼糖所采用的工艺路线大幅缩短，也大幅减少能源消耗，更重要的是，本发明生产工艺不添加任何化学添加剂和外界水，产品所含物质100％来自甘蔗本身，且能全部采集到并保留甘蔗中的丰富营养成分，因此采用本发明生产工艺制成的粉糖和液体糖浆和市面上所有的白糖、黄糖、红糖、液体糖浆均不相同，其包含了甘蔗中所有的营养成分，而且干净、卫生，是一种全新的、之前人们无法吃得到健康食品。
