Productivity when moisture content is reduced from 20% to 14% when wheat is dried, no more than 6 t / h. Air consumption in the cooling section, at least 300 m3 / h. Temperature of the product, not more than 60 ° С. Power consumption is 15.6 kW. Type of fuel - natural gas. Grain dryer uses dry air as a drying agent, ensures the absence of carcinogenic components of fuel in grain (currently the content of benzyrene in grain products is strictly regulated), improving the quality of grain. Grain dryer provides specific heat energy consumption not more than 3.5 MJ / kg of removed moisture, which is 1.5 times lower than the existing convective dryers. In comparison with convective dryers, the drying time is reduced by 10% with practically identical overall installation parameters. Reduced fuel consumption to 0,097 m3 / kg. The coefficients of heat transfer in a ball heater from the surface of the thermosyphons to the grain flow 80 ... 85 W / (m2 K). The payback period of the dryer is no more than 3 seasons. A sample of grain dryers based on thermosyphons with a productivity of 6 t / h can be used for processing: small seeds of seeds; selection seeds; grain directly from the producer. The developed calculations programs can be used to deepen the analysis of the internal mechanism of drying, so to calculate the parameters of innovative dryers of different productivity.
