EVALUATION OF THE ECONOMIC EFFICIENCY OF HELIO-DRYER WITH THERMAL BATTERY AND USING THE SOLAR ENERGY
Journal Title: Проблеми і перспективи розвитку підприємництва - Year 2015, Vol 2, Issue 1
Abstract
The article is based on the economic feasibility of reducing energy intensity, direct operating costs in the process of drying fruits in the drying installation through the use of renewable energy sources (In technology of solar drying). Nowadays such drying installations are widely used in collective farms and other industries, agriculture of Ukraine. The works to improve the design of dryer installation and drying technology is very actual problem that requires the solution and can improve economic efficiency of production and energy resources saving: of thermal and electric energy. When carrying work on the improvement of design the acting system must be selected basic pattern similar device to compare its techno - economic indicators. In particular, in order to increase the efficiency of the process drying in machine is proposed to establish a thermal accumulator with a solid material for thermal accumulating, that allows to increase economic efficiency of the drying process by 20%, reduce energy intensity by 15%, specific energy costs by 10%. direct operating costs by 5%, the electricity consumption 128.5 kVt∙h/kJ through the use of renewable energy sources.( particularly solar energy). The expected economic effect due the developed technology combined drying using a thermal battery with a solid heat accumulated material weighing 50 kg and air collector area of 1,5 m2 and using renewable energy sources will be 1.8 thousand. UAH/year season when loading 9.2 kg of drying material and drying cycle of 50 hours.
