Bulk-type dryers which are widely used for drying special agricultural products such as tobaco leaf, red pepper, mushroom, ginseng, medicinal herb, etc, began to be distributed on a full scale since 1980 and the total number of dryers introduced to farms reached to about 36,600 units as of the end of 1986. In this study a survery was carried on the farmers cultivating special crops, dryer manufacturers and related administrative institutes and associations by means of on-the-spot investigation, mail or interview to collect data on scales and patterns of farming, utilization of bulk-type dryers, production and price streams of the special crops etc. Based on the analysis of the data surveyed predictions were made for the total demand on the bulk-type dryers and for annual demand over five-year span.
