SCIENTIFIC SUPPORT OF COMPOSTING MIXTURES PRODUCTION TECHNOLOGY IN THE PROCESS OF MANURE FROM INDOORS
To eliminate the negative aspects of the existing domestic and foreign production technologies based on manure compost mixtures proposed fundamentally new technical means for moving manure through longitudinal canals in the form of a rod conveyor with a hydraulic actuator of the traction circuit, feeder-dispenser of moisture-absorbing materials and mixing and conveying device installed in the transverse canal. This set of equipment provides the possibility of obtaining a compost mixture with the required physical and mechanical characteristics at the output of the livestock enterprise. Thus, it is possible to reduce the number of operations, improve the quality of the resulting mixtures, reduce the energy intensity of the process, eliminate the possibility of environmental pollution, etc. As a result of theoretical and experimental studies, the performance of the rod conveyor andthe specific energy consumption depending on the design features, physical and mechanical characteristics of manure and the degree of filling of the channels. When the length of the stroke of the traction circuit is 2.8 m, the step placement of the scraper 1.0 m maximum capacity of the conveyor is 7.3 t/h, the specific energy consumption of 0.3 KWh/t. Length of the mixing-transporting devices shall not be less than 1.5 m. With an increase in the mixing length from 2.0 to 6.0 m, the power consumption increases by 78% in the production of peat - slurry mixtures and by 59% in the production of Straw-manured-slurry mixtures.
