Herbaceous biomass that has been solar-dried and baled can be transported to processing or storage sites without appreciable difficulty with existing equipment. However, this can entail a significant cost. Ordinarily such materials would be loaded directly in the field on a low-bed truck. Standard bales (60-80 pounds) can be loaded manually or with mechanical loaders requiring only one laborer on the truck for final positioning of the bales. Bulk bales would be stacked two layers deep on the truck bed with tractor-mounted loaders. The same truck would transport the biomass to a final... 

Delivery costs will vary considerably with the individual biomass production operation. In general, a 40-ton low-bed truck with driver can be hired for about 180 per 24-hour day at current rates. Loading equipment with operators must be stationed at each end of the delivery run. In an ideal biomass production operation, i.e., one managed by a private farmer for profit, the land owner would probably own and help operate the truck and accessory equipment. An estimated delivery cost for solar-dried biomass on a 20-mile run would be 6.00 to 8.00 per ton (1980 dollars).

Solar drying provides the desired reduction of losses together with improved quality of the dried products. 

Accordingly, the availability of solar energy and the operational marketing and economy reasons offer a good opportunity for using solar drying all over the world. A great number of successful practical applications have already been reported [152,155-174,206,211,215,217],...
