Design and Development of Solar Assisted Tray Drying System for Khoa Powder Preparation
No full textA solar parabolic trough concentrator (PTC) air heater was designed, fabricated and coupled with an electrically operated tray dryer for drying Khoa, which was then converted to Khoa powder. The designed solar PTC air heater had collector aperture width of 1.016 m, collector length of 1.970 m, focal length of 0.226 m and rim angle of 96.6° with collector aperture area of 2.0 m2. Two receivers made up of galvanized iron and aluminum coated with black paint on the surface were tested. Parameters like direct normal irradiance (DNI) and temperatures were recorded along with atmospheric air, receiver output air and receiver surface temperature from 9:00 h to 16:00 h. The average maximum outlet air temperature, receiver surface temperature and thermal efficiency were observed to be 62.8°C, 159.4°C and 21.71%, respectively for the galvanized iron receiver and 67.8°C, 170.4°C and 23.69% for aluminum receiver coated with black paint, respectively. The Khoa was made from full cream milk and dried in an electrical tray dryer coupled with solar PTC air heater at 55°C, 60°C and 65°C. The average thermal efficiency of the tray dryer at 55°C, 60°C and 65°C was 20.44%, 23.33% and 27.46%, respectively. The average requirement of energy per kg moisture evaporation at 55°C, 60°C and 65°C was obtained at 3.25, 2.84 and 2.41 kWh, respectively. A comparative investigation on energy consumption for Khoa drying in a tray dryer without a PTC solar heater (2.65 kWh) was about 2.5 times compared to electrically heated tray dryer coupled with PTC solar heater (1.04 kWh)
Mapping Energy Flow in Crop Production Systems of IGKV Farm Raipur: An Input–Output Analysis
No full textEfficient utilization of various energy sources plays a critical role in enhancing agricultural productivity, profitability and overall economic competitiveness. This study was conducted to analyse the energy efficiency of selected crop production systems at the research farm of Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur. The energy consumption for each crop production operation was systematically recorded and analyzed using a custom C++ program. The study revealed that, operation wise, irrigation consumed the highest energy (3359 MJ ha-1), followed by seedbed preparation (2305.43 MJ ha-1) and transplanting (628 MJ ha-1) among the selected crops. The source-wise, fertilizer usage accounted highest energy consumption for wheat (6927 MJ ha-1), followed by rice (6152 MJ ha-1) and linseed (2145.47 MJ ha-1). The energy output-input ratio was highest in rice (11.43), followed by chickpea (9.31), wheat (5.73), and linseed (4.80). Specific energy required for crop production was lowest for rice (2.60 MJ kg-1), followed by chickpea (3.35 MJ kg-1), wheat (5.18 MJ kg-1), and linseed (9.10 MJ kg-1). These results highlight the energy-efficient crop production systems at IGKV farm with significant implications of sustainable agricultural practices. The developed C++ program provides a unique and user-friendly interface for analysing energy consumption in different crop production systems
Agricultural Policy and Budgetary Reorientation for a “Viksit” Bharat
No full textIndia, despite being a world leader in the production of agriculture, horticulture, spices and condiments, milk, egg and fish, has a poor share in world exports amounting to barely 6.84 per cent. Productivity and yield is less than a third in that of competing companies, and the domestic market in most commodities is protected by high tariff walls. This scenario of un-competitiveness is of concern. Furthermore, much of agriculture and horticulture produce (about 10 per cent) is lost due to post harvest, processing and logistics infrastructure related gaps
