孔板により仕切られている。 Conventionally, these drying methods have been carried out by a batch processing method or a continuous processing method.
In the batch processing method, the material to be dried is placed in a container and heated while stirring for a certain period of time to dry the material. Further, in the continuous processing method, hot air and the material to be dried are passed through a cylindrical container while being stirred to dry the material, and the cylindrical container is partitioned by a plurality of perforated plates having the same shape.

The above conventional method has the following problems. That is, in the batch processing method, if an attempt is made to dry the entire product, some parts will be extremely heated and the dried material will be oxidized, making it impossible to use it as feed or the like.

The present inventors have conducted various studies on the causes of non-uniform moisture content of products in the continuous processing method in the prior art and methods for solving the problem. It was discovered that the reason why air was passing through the container was because the shape of the partition plate that partitioned the container, that is, the disk screen, was inappropriate. The present invention was completed by discovering that the aperture ratio should be made smaller in the direction in which the drying material flows, and the area of the holes themselves formed in the disk screen should also be made smaller in the direction in which the material to be dried flows.

The flow rate of the material to be dried flowing from the upstream side to the downstream side of each chamber partitioned by a disk screen in the container is determined by the fact that the amount of material to be dried is large in the upstream chamber, and also depends on the aperture ratio of the disk screen and each through hole. The larger the area, the larger the area. In steady state, the amount of material to be dried passing through each disk screen is equal to the amount of material to be dried that is injected, so the amount of material to be dried in each chamber in steady state is equal to the amount of material to be dried in each chamber. The average residence time of objects is determined by the aperture ratio of the disk screen and the area of each hole. The average moisture content of the dried material in each chamber gradually decreases from the upstream side to the downstream side, and the variation in the moisture content of the dried material obtained by changing the average residence time of the dried material in each chamber also increases. It is thought that it will change. In fact, as a result of experiments conducted by the present inventors, the distribution of the moisture content of the dried material changes greatly depending on the aperture ratio of the disk screen and the area of each hole, and these values are gradually decreased from the upstream side to the downstream side. It was found that high uniformity of water content could be obtained by doing so.
