Due to spectral transparency and flexibility of plastic, it is used in dryers in modern greenhouses. Helio dryers use plastic as a case for chamber providing sunlight and heat protection. This study highlights the use of plastics in the dryer heated by solar energy and includes the calculation experiment on determining the flow function and speed vortex of drying agent with different geometrical parameters of drying chamber. A technological scheme is presented and operation of the proposed dryer is described. To justify camera parameters, the Navier-Stokes equation is used. This problem is solved by a sweep method using numerical calculation, and flow function isolines and speed vortex in the form of graphs are obtained.
