減少を図ることが要求されている。2. Description of the Related Art For example, a large amount of wastewater generated in a plating plant or the like is usually added with a chemical agent or a polymer flocculant, and allowed to stand still.
In many cases, the concentrated liquid is usually filtered and outsourced to an industrial waste treatment company as industrial waste. In this case, the processing cost is calculated by the weight of the object to be processed and collected by the trader. However, since most of the material to be treated is water, it is required to reduce the water content of the material to be treated and to reduce the weight and volume.

のなどが知られている。In the case of the above-mentioned plating factory, compression filtration is carried out by a filter press, but the water content is still about 80%, and it is considered that the drying treatment is suitable for further lowering the water content. Conventionally, as a device for drying a cake-like material after being compressed and filtered by a filter press, a system in which a cake-like material is supplied between a pair of heating drums and dried while being crushed, A rotary kiln type is known.

理時間が短く、ドラムを多段設置したり、ドラム径を大
きくする必要があり、装置が大型化し、高価となる点で
ある。In the system using the pair of heating drums, the cake-like material is crushed and thinned, and since both sides of the cake-like material are heated by the heating drum, the cake-like material is heated.
Although it seems that it is advantageous for drying the cake, the disadvantage of this method is that the utilization efficiency of the outer peripheral surface of the heating drum is poor and most of the outer peripheral surface is always in non-contact with the cake. This is because the heat treatment time is short, drums must be installed in multiple stages, and the diameter of the drum must be increased, which makes the device large and expensive.
