Kanpyo (or dried gourd shavings) is a fruit of the bottle gourd. The structure consists of a lot of fiber and 95% water. We noticed this structure and performed the basic preparation of a new desiccating tablet. First, we got powdered Kanpyo product from the mill crusher. The water-absorbing performance of the powder was confirmed in a saturated container. Next, the powder was pressed by a press machine (3.0t, holding time 5min). The water-absorbing performance of the tablet was also confirmed. The results showed that the Kanpyo powder continued absorbing water under the saturated condition for 340 hours. The powder was able to absorb around 60wt%, while the tablet had the water-absorbing capacity of 50wt%. On the other hand, a fault of both the powder and the tablet was that mold was detected in the absorbed water.

Key words: kanpyo / dried gourd / desiccating tablet
