DESIGN AND CALIBRATION OF A DRYING SYSTEM FOR OKRA 3.pdf Download (384kB) |
Abstract
Because of the wide acceptability of okra fruits as vegetable and when okra seed is roasted and ground could be used to form a non-caffeinated substitute for coffee, the development and calibration of an affordable dryer used in drying okra was done as part of effort to eradicate post-harvest losses usually experienced in developing countries due to the heat of respiration that causes temperature to rise quickly and thus result to rapid deterioration. The developed dryer is a rectangular structure having a holding capacity of 2.4m3. The calibration was done by carrying out two different tests, the air distribution test and temperature distribution test. In the air distribution test, the velocity of the blower was measured to be 3.6m/s using a device known as anemometer. Temperature distribution test was carried out to know the distribution of temperature on each of the tray at different preset temperatures. This test was carried out for 2 hours for each preset temperatures and readings were taking at intervals of 20minutes. The maximum and minimum values of temperature obtained during the test period with preset temperature of 450C-700C are 340C and 750C respectively. More so, the square of the regression coefficients r2, relating the temperature on trays to the preset one indicates a statistical correlation between the temperatures as the values obtained are positive. The maximum and minimum temperatures recorded for the ambient temperature are 360C and 270C respectively.
