Therefore, it takes a long time of several months to satisfy the dry condition that can be used as a crude drug, and the productivity is poor. Therefore, as a measure to solve the inconvenience caused by natural drying (sun drying),
It is possible to use a forced drying method to dry the medicinal herbs by using the existing forced drying equipment that uses thermal power, but the existing drying equipment is expensive, and since it is a structure, it is necessary to secure a site for installation and to take a large amount of time. Installation work is required, which not only increases the production cost of herbs due to capital investment but also makes management difficult. That is, medicinal plants, for example, in the case of Toki, are harvested around the end of autumn (November to December), and dry preparation is performed only during this harvest time, and the drying equipment is not operated throughout the year. Therefore, the period of non-use is longer than the operating period of the drying equipment (the harvest time of the day),
This will cause a sharp rise in terms of production volume for the time being and management of the unused period. Furthermore, since the existing drying equipment is manufactured and sold in the planned size, it was assumed that medicinal herbs were fully loaded in a mesh container and lined up in the equipment (drying room), or stacked and forcedly dried. In this case, since the dry atmosphere (temperature distribution) in the equipment tends to differ depending on the location, the location where the mesh containers containing medicinal herbs are regularly arranged is changed, or the upper one and the lower one are stacked. It is necessary to perform troublesome and troublesome work such as having to perform.
