Criteria and of soils grouping on fitness of humus layer for recultivation and soiling

Abstract

The purpose. To determine technical-technological parameters of new power-saving complex which consists of standard chamber corn dryer and generator of warm, working from incineration of rods of corn. Full substitution of traditional not restored power resources on vegetable biofuel ensures saving of power. Methods. Generalization of literary data, holding experimental, laboratory and field experiments. Results. Basic technical-technological indexes of new power-saving complex, namely temperature and ventilation regimes, parameters of relative humidity of working and completed heating medium, speed of drying, drying capacity and quality factors of the exsiccated seeds are specified. The temperature regime in the complex oscillated within the limits of 38–43°C, depending on damp of corn cobs. Ventilation regime consisted depending on power of ventilation aggregates and service conditions of fuel-air compartment. Relative humidity of working heating medium made 10–12 %, completed — 20–44 % depending on stage of drying. Speed of drying oscillated within the limits of 0,16–0,39  %/þ, productivity made 1,2–6,0  t-%/hour, depending on mass of corn cobs, their damp and exposure of drying. New method of drying had no negative effect on quality of seeds of hybrids of corn and their parent ingredients. Conclusions. Technical-technological parameters established by authors may be recommended for new power-saving complex and ensure fast and uniform mealies drying, exit of high-quality conditioned seeds, full substitution of traditional fuel (liquid, gaseous) for biofuel (plant residues).
