ENERGY AUDIT OF TECHNOLOGY FOR THE WET FORAGE GRASSES PROCESSING

Among the many processes that are used as food industry and fodder production, one of the most common is energy-intensive drying process. The total potential energy when drying forage grasses, defined by the difference between the actual and theoretical fuel consumption for evaporation of 1 kg of water varies in the range of 0.86 - 1.3 MJ/ kg. In modern conditions of growing shortage of animal feed raw materials and energy crisis urgent even finding ways to reduce the cost of fuel and energy resources by implementing innovative technologies moist feed extrusion facilities in mixtures with other components of feed. Purpose is to determine the internal potential energy in fodder production using as raw wet feed facilities without their prior or subsequent drying by the example of fodder grass alfalfa. Object is a technological processing of wet forage grasses in the composition of animal feed. Determined that in the basic and traditional technology is the most energy intensive process ektruduvannya because it consumes energy of 500 mJ / m, the new - 423 MJ / t. What does the new technology to process 57% of the total cost of electricity, and the base - 49%, due to additional load on the extruder - dehydration. On evaporation of 1 kg of water during extrusion energy consumed 2.94 MJ / kg, which is close to the maximum theoretical value of 2.7 MJ / kg. Thus potential energy (0.24 MJ / t) in this case is minimized. The conducted energy audits of base (conventional) and new technologies of production of animal feed products with the inclusion of forage grasses showed that as a result of the process of extruding the purpose of dewatering new technology is energy efficient compared with the conventional technology of drying forage grasses and subsequent production of grass meal inclusion and hence economically feasible, as is the overall economy of energy resources 714 MJ / t (47%)
