３要素の値は、原液の物性によって異なる。In the above screw press, the dewatering performance largely depends on three factors: the compression ratio of the transfer compression passage, the length of the compression chamber, and the outflow resistance at the outlet of the compression chamber. In addition, the values of the above three factors for obtaining high dehydration performance differ depending on the physical properties of the stock solution.
