Air Heating Solar Collector for Hemp Drying

Ilze Pelece, Semjons Ivanovs, Adolfs Rucins, Oskars Valainis


Attempts to use solar energy for drying of hemp (and other agricultural production) have been made in this work. Air is heated in solar collector approximately to 40 – 60 degrees Celsius, which also results in decreasing of the humidity of this air from 60 % (normal ambient air humidity) to 18 - 8 % respectively. Then such hot dry air is used for drying of hemp or other agricultural production.
A new construction of air heating solar collector – a cylindrical solar collector has been worked out.
