The reason why we can make beer carefully is because people's requirements for beer quality are constantly improving. Beer equipment and machine are also carving out the craft, sharing the filter sterilization method -- cotton cake filter. Cotton cake filter is a relatively original filter equipment, and now it has almost quit the historical stage.
    Even so, we'll give you a brief introduction. Because the modern plate frame type diatomite filter is developed and expanded according to its basic theory. At the same time, the filter has been in use for decades. The method of making filter cotton is to make filter paper oars by degreasing wood fiber or cotton fiber paper oars. It is used as filter medium for beer.
    The size of filter cotton is usually 4.0-4.5cm thick, slightly thick between the center, the thickness difference is not more than 0.5cm, the edges are regular and have no rough edges. Cotton cakes are usually made of air pressure or water pressure, and are stored in a low temperature and clean place for no more than 24 hours. The filtration capacity of cotton cake is usually 500l/m2

    The advantages and disadvantages of the cotton cake filter are as follows: the filter cotton and asbestos are mixed, the adsorption capacity is strong, the beer with high stability is filtered out, and it is clear and transparent. Disadvantages: it takes time to make filter cake. It is difficult to complete automation because filter must be disassembled every time.
