Teach you how to solve the problem of floating scum

The purpose of processing the scum is to better improve the purification work, to make good use of the sucrose in the scum, and to prevent the contents of the scum from deteriorating. If we cannot handle it well, the effect will be biased and even side effects may occur. When we perform phosphorus treatment, there is relatively little scum, and it is not difficult to deal with. It only needs a suction filter to handle it.
Generally speaking, in foreign countries, the scum will be returned to the mixed juice and processed by clarification. I heard that this is because the calcium phosphate and flocculant in the scum can still act. You must know that after the scum is formed, there will be redissolution during the dilution process. And the greater the dilution of the scum, the more redissolution it will contain, which we need to pay attention to. For example, the scum and different water are mixed and stirred for three minutes, and then filtered at a temperature of 95°C.
