Wort filtration is one of very important process of saccharification stage, the quality of wort filtration, to the yield and matter of beer
Amount has important influence.The major requirement of wort filtration is: obtaining higher extract recovery rate；Realize the faster rate of filtration
Shorter filter cycle；There is higher wort quality, is often referred to lower turbidity and few oxygen absorption.Wort filtration point
To filter and washing poor two processes: filtering is the filter layer that wheat juice is made up of wheat grain layer and filter medium (plate or filter cloth), is obtained
To supernatant liquid, the wheat juice in this stage is known as slubbing (original) wheat juice or filtering wheat juice.Washing grain is washed with hot water (i.e. cleaning solution)
Remain on the extract in wheat grain after slubbing wort filtration out, obtained wheat juice is known as the second wheat juice or washing wheat juice.The two
Process is mechanical-physical process.Traditional wort filtration method is broadly divided into three kinds: filter channel process quickly oozes out channel process and filters pressing
Machine method, wherein filter press method is divided into traditional filter press, bag type filter press, novel van-type (can be with squeeze diaphragm) filter press again,
