Cake washing dewatering before

Is it always best to dewater before cake washing ... 

When cake cracking does not occur or its effects can be neutralized, dewatering before washing is beneficial. 

The shape of the washing curve depends on many variables (as shown later) and one important one is the amount of dewatering done on the cake before washing. Figure 10.6 shows a case when no dewatering is done, i.e. the cake is full (saturated) of the mother liquor to start with. If the cake is well dewatered, the curve is much lower because much less mother liquor needs to be removed. Partially dewatered cakes would result in curves in between these two.
