Kanpyo (dried gourd shavings) consists of a lot of fiber and 95% water. We noticed this structure and performed the basic preparation of a new desiccating tablet. In a previous study, we reported on making a kanpyo desiccating tablet. This tablet showed water-absorption capability around 50-60 wt%. On the other hand, the tablet was fragile after absorbing the water. In this study, we examined how to increase the strength of the tablet. First, kanpyo powder was added to seven kinds of binders individually. Next, the powder was pressed by a press machine (3.0t, holding time 5min). The water-absorbing performance of the tablet with the binder was confirmed in a saturated container. The results showed that tablets with and without the binder continued absorbing water under the saturated condition for 300-350 hours. However, the tablets showed mold growth after 400 hours. Absorbed water was detected in the tablet that included the binder.
