    • The present invention refers to an apparatus and a method for filtering liquid products, particularly wine. The apparatus includes a filtration bell (5) provided with filtering means (6) and connected to an inflow circuit (13) and a first outlet circuit (14) of the retentate, and to a second outlet circuit (18) of the filtered liquid. The apparatus also includes:—a monitoring and control unit (21);—a first and second sensing means (22,23) suitable for detecting the value of a first pressure PT1 in the first outlet circuit (18) and of a second pressure PT2 in the second outlet circuit (18);—flow rate detection means (17) for detecting the value of a first flow rate FIT in the second outlet circuit (18); value means (15,16) arranged in the second circuit (18) downstream of the second sensing means (23). The monitoring and control unit (21) includes means to control the closure of said valve means (15,16) and to start a process of backwashing said filtering means (6).

    • The invention relates to a process for the crossflow micro-filtration of beer. In order to prevent the clogging of the membrane of the filter module by components of the non-clarified beer which are to be filtered out and settle in the form of a covering, the filtration is interrupted at intervals. In a subsequent brief pause the covering on the membrane is chemically and partially dissolved with a caustic solution whereafter the covering is subsequently removed by backwashing of the membrane with water. In order to further improve the filtration, the transmembrane pressure (p) is regulated during the filtration phase according to a substantially periodic time function, and the crossflow velocity (v) of the beer over the membrane is increased substantially continuously.
    • 本发明涉及一种用于啤酒交叉流微量过滤的方法。 为了防止过滤组件的膜被堵塞的未澄清啤酒的成分被滤出并以覆盖物的形式沉降,过滤被间歇地中断。 在随后的短暂暂停中,膜上的覆盖物用苛性碱溶液化学和部分溶解,然后通过用水反渗洗膜来除去覆盖物。 为了进一步改善过滤,跨膜压力(p)根据基本上周期的时间函数在过滤阶段被调节,并且啤酒在膜上的交叉流速(v)基本上连续地增加。
