    • ABSRACT - [ Total Page(s): 1 ]ABSTRACTDrying is out of the major problem in post harvest operation. The traditional method of  Drying (Sun drying) is weather dependent and unhygienic which affect food storage most especially in developing countries like India where more than 3300 to 3700 hours of bright sunshine per year available in North- West and West coastal region. The dryer consist of the following operating component parts: a cabinet, blower, trays, temperature controller, copper wire and light emitting Diode (LED) screen and switch. The factors considered in the study were turmeric of 2000g weight, temperature (50 ... Continue Reading

      CHAPTER ONE - [ Total Page(s): 4 ]CHAPTER ONEINTRODUCTION1.1    Background to the StudyDrying is the dehydration process used to remove the moisture present in food products by the application of heat.  The heat may be supplied either by hot air or from the biomass energy.  Drying process is used to preserve the food products for future usage.  Drying prevents the growth of bacteria and yeast formation.  Drying can be achieved by using open air and biomass dryers. (Atul et al, 2014). Drying has a vital role in post harvest processing. It has always been of great importance for conserving agricultural products and for ex ... Continue Reading

         

      CHAPTER TWO - [ Total Page(s): 7 ]Dhanushkodi et al (2015) developed a biomass dryer fir small scale cashew kernel drying.  The components are heater, blower and drying chamber.  Performance characteristics of the biomass dryer including system efficiency has been evaluated experimentally based on drying of 40kg of cashew kernel.  The dryer is capable of producing hot air continuously with temperature ranging between 700 C to 750C.  The performance analysis showed that the moisture reduction from 9% to 4% was achieved within 7 hours in biomass drying and it had taken almost 15 hours in open sun drying.  The system efficie ...

      CHAPTER FOUR - [ Total Page(s): 5 ]The initial moisture content of Turmeric after harvest was 43% fresh weight basis. As drying temperature increases, moisture percentage decrease and as drying time increases, moisture content decreases as will.Hence, analysis of variance (ANOVA) shows that the cutting and drying temperature is significant at 5%. This work is related to the research conducted by Phagu, (2015) who reported that the best drying rate of turmeric is 60oC at 3mm. ... Continue Reading
