様のものが多い。2. Description of the Related Art Yeast and other solid substances remain in beer that has been fermented and aged in the process of producing beer. Therefore, beer that has been fermented and matured needs to be filtered through a filtration device. The device used for such filtration has a specification of a multi-stage (usually a two-stage one is often used in consideration of cost etc.) filter in order to completely remove the residue in beer as much as possible. There are many things.

れる。After the beer filtration process is completed by using such a beer filtration device, the filter layer in the filtration device is usually washed, and thereafter, the filtration device is prevented from coming into contact with air. It is filled with fresh water for the purpose of keeping it as it is.

As a method of driving operation of this kind, beer to be replaced is simply supplied to the beer filtering device, and after passing through the device,
The so-called extrusion operation of draining water is generally used, whereby the fresh water in the apparatus is gradually replaced with beer.

There was a problem. In addition, although various improved operation methods were attempted in order to quickly switch from fresh water to beer, this time, pressure fluctuation during operation became large and stable filtration could not be performed, or in severe cases There is also a problem that the filter layer (precoat) of diatomaceous earth is peeled off to cause turbidity of beer.

【００２６】従って、従来の方法に比べて、急峻な切り
替えが可能なためビールと水との混合液の発生量を５０
％程度減少させることができる。Therefore, as compared with the conventional method, the amount of the mixed liquid of beer and water generated is 50 because abrupt switching is possible.
% Can be reduced.
【００２７】また、入口および出口の流量をリンクして
バルブを閉動させるため濾層を通過する流量が一定とな
り安定した濾過ができる。Further, since the flow rate at the inlet and the flow rate at the outlet are linked to close the valve, the flow rate through the filter layer becomes constant and stable filtration can be performed.
【００２８】また、バルブの閉動を徐々に行うために圧
力変動が小さく安定した濾過ができき、さらには珪層土
濾過層（プレコーティング）剥離の防止もできる。Further, since the valve is gradually closed, the pressure fluctuation is small and stable filtration can be performed, and further, the siliceous earth filtration layer (pre-coating) can be prevented from peeling.
