Assuming that solar dryer system using the green house as a solar collector is incorporated into the mechanized rice cropping operation system most popular in our country, studies were made to determine the facility scale of dryer system required for performing grain drying smoothly. The salient points obtained are as follows: 1)First, study was made concerning how much holding capacity is required for the grain dryer utilizing solar energy. Formula (2-2) was proposed with which the optimum holding capacity of the dryer can be calculated on the basis of daily harvesting amount of grain by combine. Next, required drying quantity per day was determined from the standpoint of full use of the drying the proper harvesting period. Then formula (2-5) was derived as a calculation formula to obtain that holding capacity of a dryer which is calculated on the basis of above required drying quantity.2) By picking up factors having effects on the area of a solar collector house, all of those characteristics are made clear. From these date, formula (2-11 & 2-12) were proposed to calculate adequate area of the collector house. House area (㎡)/Grain (100㎏) and Air volume <special> (m3/sec) <special> House area (㎡), required for calculation of adequate house area, in relation to the collector efficiency of the house, air temperature rise within the house and drying rate, were represented graphically based on the results of experiments conducted up to the present. Numerical values required for calculation of adequate house area can be read there-from.
