If only a couple hours between infusions, please no need to store or dry. Just bring along in the teapot or mug or gaiwan. Very quick wash with hot water before steeping again. If no need to bring out, leave a small opening at the lid so not too hot inside pot to turn tealeaves bad.
Storing too long between infusion is not good no matter what method. Some old people dry used tealeaves to use again, but taste is no good.
