Drying of Chili Using Solar Cabinet Dryer & Analysis with Results of Various Parameters
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
Solar Energy will going to be 5th generation main energy sources with its easy availability and scarcity of nonrenewable energy sources. With increasing demand of energy sources to harness our daily needs and scarcity of coal and petroleum products it will be a better option to depend upon more reliable renewable energy sources. Various research works are going on solar energy but it still many more to be done to fully depend upon its utilization. Objective of the present study was to carry out detail experimentation and then analyze solar cabinet dryer. The loading capacity of the dryer was about 2kg of fresh product per batch. The dryer is of both natural and force mode type based solar cabinet dryer. The experiments were carried on both natural and force mode by using chili as the raw product. Various readings related to temperature and humidity at the desired points were measured with the help of thermocouples and hygrometer respectively, also air flow rate and solar intensity were measured with the help of anemometer and pyrometer. These experiments were carried in ITER, SOA UNIV Bhubaneswar (India), in this various parameters related to solar dryer was not only calculated but also natural and force mode was compared in terms of drying rate. The data are presented in terms of tables and graphs. It was found that the drying of chili in natural mode would take around 50-56 hrs and drying in force mode will take about 10-21 hrs depending on whether we are using heater as an external source of heat or not. It will take around 105 hrs in open drying of chili. The chili was reduced from the initial moisture content of 86.5(wb) to 7.3(wb).
