Drying Hemp in a Container Kiln Dryer with a Capstone Turbine C800:
Using the Capstone Turbine to dry hemp in combination with a conveyor dryer or drum dryer, expect the following throughput based on 970 btu to evaporate 1 pound of water. The Capstone Turbine exhaust can be mixed with dry outside air to direct heat a hemp dryer. Alternatively, put output into a stainless steel pipe and then use fans to circulate and heat air in dyer. This is in the true sense cogeneration (produce both usable heat and power at the same time). The power can be used to run fans, or exported to the grid for utility buyback (typically more hassle and low buyback rate than it’s worth). Because this is dual mode, you can trailer mount this module along with a trailer mounted drum dryer or conveyor dryer module for portable drying (bring to the farm fields directly). You will need a propane tank trailer and associated interconnection equipment to fuel system. Alternatively, you can truck in the hemp flower from the fields in a hub-spoke system.
C800 Net Heat Rate: 10,300 BTU/kWh x 800 kW power = 8,240,000 btu/hr
8,240,000 btu/hr / 970 btu/lb/water = 8,494.85 lbs water
Heat Available for Evaporation: 8,240,000 btu/hr available / 970 btu/lb/water evaporation = 8,494.85 lbs water evaporated per hour under standard conditions.
Hemp Production Per Acre Variables: One acre of hemp flower drying to 10 percent moisture content (i.e. removing 90 percent water weight):
500 lbs per acre hemp flower harvest: @ 90 percent evaporate = 450 lbs –> 8,494.85 lbs water (c800) / 450 lbs = 18 acres per hour
1,000 lbs per acre hemp flower harvest: @ 90 percent evaporate 8,494.85 lbs water (c800) / 900 lbs = 9 acres
1,500 lbs per acre hemp flower harvest: @ 90 percent evaporate 8,494.85 lbs water (c800) / 1,350 lbs = 6 acres per hour
2,000 lbs per acre hemp flower harvest: @ 90 percent evaporate 8,494.85 lbs water (c800) / 1,800 lbs = 4 acres per hour
