Description

用于冲积的改进助滤剂
本发明涉及具备改进特性的被用于冲积的助滤剂。
本发明涉及这种助滤剂在过滤任何液体、尤其是啤酒、葡萄汁、葡萄酒或其它饮料方面的应用。
助滤剂是一种分散体，当通过将其放在筛网或载体上被单独使用或与待保留颗粒混合用于固-液分离时，主要通过机械作用提供或改进分离效率。
该效率可以定性地与所获得的滤液例如其纯度或无菌性有关或通过滤液流速的增加而定量相关。
所用的主要助滤剂为：
由硅藻土煅烧而成的硅藻土、构成浮游生物类部分的并且通常被视为硅藻土的藻类化石；
来自火山岩、流纹岩的珍珠岩。这种被粉碎与研磨的岩石在煅烧炉中膨胀20次以上；
呈例如马铃薯粉状的淀粉；
飞灰；
纤维素；
合成材料如聚合物纤维，玻璃珠或塑料颗粒等。
这些助滤剂在过滤过程中形成能够捕集待脱除杂质并且有助于液相流动的多孔介质。
已知这些助滤剂可被用作预层或被用于冲积。
作为预层(prelayer)，该助滤剂在过滤悬浮液之前被放置在滤介体上。
在冲积过程中，该助滤剂通常通过计量泵在过滤之前与悬浮液混合。该悬浮液形成由助滤剂与杂质构成的混合饼。非常普遍的作法是为了制备充分澄清的初始滤液、保护滤介体不受可能堵塞该滤介体的细粒迁移的影响以及便于拆卸与清洗滤器在预层上冲积过滤悬浮液。
助滤剂应用的一个特别有利的场合是啤酒制造业。
欧洲专利申请EP-A-0483099描述了一种更具体地目的应用于啤酒酿造业的冲积技术的助滤剂。该助滤剂包括粒径为5～50μ、平均直径接近20μm的球形颗粒。
这些助滤剂的使用形式优选为孔隙率为0.3～0.5的饼。
这些球形颗粒为耐磨和耐再生剂并且相对地不受温度与进料质量影响的不可压缩颗粒。这些颗粒通常由固体或中空玻璃或塑料制成。
US4326964描述了一种深床层过滤法。按照该方法，带有杂质的液体渗流过滤床层，因而逐渐堵塞床层。为了延长循环时间与限制表面滤器的堵塞，人们建议构造一种由不同粒径层形成的床层，其中最大颗粒处在床层顶部，用于阻止最大体积杂质，而最细的颗粒处在滤器底部以便捕集最小的杂质。当床层被堵塞时，可以设想通过以能够发生流化的流速进行逆流清洗。该作用导致粒径不同的各层彼此混合。为防止不同颗粒的各层发生均化，建议使用其密度经过适当选择以便导致分离的材料。具体地，在粘接剂中加入中空的二氧化硅颗粒就是为实现此目的而提出的一种途径。
本发明涉及提供一种目的应用于冲击技术并且与先有技术，更具体地与EPA483099所述内容相比具有改进性能的助滤剂。
该助滤剂尤其适用于啤酒酿造、更具体地适用于目的在于啤酒澄清过程的冲积技术。
本发明基本上涉及目的应用于冲积的助滤剂，该助滤剂基本上包括受压时不变形的多角形颗粒，其被限定为最小粒径与最大粒径之比的形状因子为0.60-0.85，以平均值接近0.7为佳。
优选地，这些颗粒的粒径分布特征在于平均直径(Malvern测量值)为30～40μm，其特征还在于70％颗粒的直径为15～50μm。
优选地，通过助滤剂的密度值校正过的、构成助滤剂的颗粒的比表面积(按照BET法测定)应该小于106m2/m3。这同时表明这些颗粒应该具有低的内缩松，以免出现过度吸附现象。
这些颗粒优选地以其孔隙率为0.5-0.7、其渗透性(通过测定单位阻力而确定)在1.5达西的区域内的颗粒介质(饼)的形式被使用。
该助滤剂的密度不得比待过滤的悬浮体的密度大25％以免发生任何沉降与分离。
本发明的助滤剂预期应用于冲积技术，更具体地应用于啤酒酿造业的冲积技术。
应该清楚地理解，还可以设想使用在预层上冲积悬浮液的所谓混合技术。
通过与所谓的标准助滤剂(硅藻土)和EPA0483099中所述助滤剂进行对比，人们试图表明通过使用本发明助滤剂得到的值得注意的特性。
所谓的标准助滤剂为被用于冲积的硅藻土如通过简单煅烧得到的粉红色硅藻土或作为预层使用的硅藻土如通过煅烧与烧结得到的白色硅藻土。作为实例被提及的粉色硅藻土为CBL，白色硅藻土为DIF BO，这两种助滤剂为CECA公司产品。
此外，为了与本发明助滤剂进行对比试验还可以采用EPA0483099中所述呈球粒状的助滤剂。
表1总括了能够表述各种助滤剂特征的主要数值，这些助滤剂的基本特征在于：
其比表面积(S0)按照BET法被测定，借助助滤剂的密度得到校正，测定单位为m2/m3；其平均直径dave以及10％通过直径d10和80％通过直径d80借助Malvern粒径分析(采激光束)确定。
类似地，构成饼的原始粒状介质(不含酵母)的特征在于：由表观密度计算的孔隙率ε0；通过测定单位阻力确定的渗透性B0；借助比重瓶测量密度法确定的实际密度(ρa)。
该对比试验包括在恒压下过滤助滤剂与酵母的浓缩悬浮液，这两种组分的比值保持在等于含106个酵母/ml与100g/h1被加入的助滤剂的啤酒中该比值。该酵母浓度被视为经过离心分离的啤酒的最大值。
对含有1011酵母和100g被加入的助滤剂的2升啤酒样品进行批量实验室试验。在2巴压力下进行过滤，沉积得到的饼的特征在于：单位阻力，对相对于每千克悬浮液中固体材料的液体通过量的阻力。(测定单位为m/kg)；表观密度ρCS(kg/m3)。
表2基本上给出了上述四种助滤剂的混合介质(助滤剂+杂质)的密度与单位阻力数据。
由表2中归纳的数据可以看出，本发明的助滤剂在酵母存在下给出的滤饼的单位阻力远远低于借助所谓标准助滤剂(硅藻土)与EP0483099文献中所述的助滤剂得到的滤饼。由新型助滤剂形成的饼的表观密度高于由硅藻土形成的饼的测定值，但低于借助EP0483099所述助滤剂形成的饼的表观密度。这表明具有本发明助滤剂的滤器中压力的增加与饼的增大明显地小于具有传统的助滤剂的情况。这些优点是显著的并且能够在达到滤器的最大容许压力之前或过滤室被饼填充之前增加过滤次数，这可以最大限度地增加工业过滤器的适用生产寿命。
此外，本发明助滤剂颗粒的粒径分布与形状可以产生结构均一的饼，其优点是提高用另一流体替代一种流体的操作效率。这是助滤剂再生过程的一种明显的优点。
