farmers are able to sell the produce Solar drying was found to be the best option Studies have shown that it has been successfully used in sub-Saharan countries such as Nigeria and Ethiopia The results are better for forced-ventilated than for naturally-ventilated drying This is because the major parameters which influence drying such as temperature air flow rate and humidity are

REVIEW OF HYBRID SOLAR DRYERS Mr T B Shaikh M Tech Scholar Energy Technology Department of Technology Shivaji University Kolhapur Maharashtra India Mr A B Kolekar Asst Professor Department of Technology Shivaji University Kolhapur Maharashtra India ABSTRACT In many countries agricultural products are dried under the open sun However this way of drying degrades the quality of

Solar drying is a good option to reduce the loss and to produce good quality grains after harvesting In this study the performance of newly designed solar bubble dryer and a thin‐layer drying mathematical modeling for freshly harvested maize grain is presented This study will be useful not only for small holder farmers but also for all agricultural cooperatives in giving a sustainable

for the technology for drying their produce Third the research seeks to recommend the design and size of the solar drying technology equipment that is consistent with the amount that majority of the farmers are willing to pay for such a technology The research will contribute to the promotion of the use of the solar drying technology by introducing it to the respondent farmers thereby

Basically there are four types of solar dryers (1) direct solar dryers (2) indirect solar dryers (3) mixed-mode dryers and (4) hybrid solar dryers This paper is a review of these types of solar dryers with aspect to the product being dried technical and economical aspects The technical directions in the development of solar-assisted drying systems for agricultural produce are compact

SDSim: A Novel Simulator for Solar Drying Processes

SDSim is a novel solar dryer simulator based in a multicrop inclined multipass solar air heather with in-built thermal storage mathematical model This model has been developed as a designing and developing tool used to study and forecast the behavior of the system model in order to improve its drying efficiency and achieving a return on the dryer investment

06/04/2011This review paper included the recent progress made in heat pump assisted drying its principle mechanism and efficiency type and its application for drying of agricultural produce Heat pump assisted drying provides a controllable drying environment (temperature and humidity) for better products quality at low energy consumption It has remarkable future prospects and revolutionaries

review some of the designs and compare their performance based on their moisture removal rate KEY WORDS: Solar dryer moisture removal agricultural products 1 INTRODUCTION Agriculture is the heart of human life work and economy Preservation extends the life of agricultural products before deterioration and helps to meet the shortages in supply and reduce postharvest losses Most of the

enhance nocturnal drying The duration of crop drying in the solar dryer was shorter than that in the open air [4 5 6] And also developed a solar air heater and tested it with and without thermal storage for drying agricultural products They found that the drying process would continue at night when a thermal mass was used They have

Solar drying required 13 to 14 h drying time whereas open sun drying required 19–20 h drying time Lesser time for drying in solar dryers is due to the higher air temperature and less relative humidity inside the dryer The drying curve for medium size dryer which was found to be best on the basis of quality of dried product produced is shown in Fig
