These three dryers were selected because the shape and size of the drying chamber of all dryers were the same and capacity is 1500 coconuts (225 kg. copra) per batch. It was seen that SFC was better in the case of solar cum electrical dryer followed by solar tunnel dryer but efficiency of the solar collection was found to be the least in the case of solar tunnel dryer. Cost of drying was minimum for solar tunnel dryer and maximum for solar cum electrical dryer.Item Copra Dryers(1994) Madhavan, K.; Bosco, S.J.D.Item Copra dryers(CPCRI, 1994-05) Madhavan, K.; Bosco, S.J.D.Item Design and development of Cardamom dryer suitable for small and medium holders(Central Plantation Crops Research Institute Kasaragod - 671 124,Kerala, 1990-03) Bosco, S.J.D.Item Design and Development of power operated husking machine(Central Plantation Crops Research Institute Kasaragod - 671 124,Kerala, 1986) Bosco, S.J.D.; Vidhan Singh, T.Item Design and development of small scale palm oil extraction unit(Central Plantation Crops Research Institute Kasaragod - 671 124,Kerala, 1997-03) Bosco, S.J.D.; Madhavan, K.; Sunil Gulati; Sebastian George, A.; Singh, T.V.Item Design, development and testing of a copra dryer of 1000 coconuts/bacth using agricultural waste as fual(1987-12) Annamalai, S.J.K.; Bosco, S.J.D.Item Development of a Forced Convection Solar Cum Electrical Dryer(2002) Madhavan, K.; Bosco, S.J.D.Solar drying relies on the sun as the source of energy. It generates higher air temperature and consequential lower relative humidity, which are both conducive to, improved drying rate. But during the drying process if the sky becomes cloudy or it starts raining, the temperature comes down and the product gets spoiled. Unlike other crops, coconut endosperm is exposed while drying and so is more likely to get infected with fungus and bacteria if the drying air temperature is less than 50°C. In order to control the spoilage and to have faster drying a forced convection solar cum electrical dryer has been designed with solar energy as the main source of energy and electricity as the alternate source of energy. It consists of a semi circular parallel plate solar collector, electric heaters, blower motor and the drying chamber. Hot air is drawn from the solar collector and blown in to the drying chamber. When the temperature in the drying chamber goes below the preset value (55°C for coconut), electric heaters get switched on and the temperature is retained between 55°C and 70°C thus drying at a uniform temperature and producing quality copra. The capacity of th dryer 3 is 2000 coconuts per batch and the drying time taken is 24 hrs. The cost of the dryer is Rs.400001- and the drying cost per Kg of copra is Rs.1.05.Item Development of a solar tunnel dryer for plantation crops(2004-12) Madhavan, K.; Bosco, S.J.D.Fresh coconut kernel containing 45 to 55% moisture content (M.C.) has to be dried to 5 to 6% moisture level in order to obtain good quality copra. The common practice of getting copra is by sun drying the fresh coconut kernel on cement floor or on sand floor for seven to nine days. Unlike other crops, while drying. the endosperm of coconut is exposed to dirt. Prolonged drying also results in microbial infection. Drying using solar dryers and indirect dryers produce good quality copra in a shorter time. So a solar tunnel dryer of a semi cylindrical shape with a capacity of 1500 coconuts I batch or 200 kg of pepper was developed. The temperature inside the dryer was 20-25" C higher than the ambient and the R.H. value was 20 - 2 2 8 lower than the ambient. Since the drying was done continuously much above the ambient air temperature and at lower R.H. level, the copra was 3 - 4 times less infested by fungi and bacteria than that produced by open sun drying. Drying time for copra was 32 sunshine hours. The cost of the dryer is Rs 136501 and the cost of drying one kg of copra is Rs. 1.15 and for pepper Rs.1. The dryer can also be used to dry other plantation crop / produces.Item Diversified uses of coconut(2004) Madhavan, K.; Bosco, S.J.D.Item Effect of extraction processes on physiochemical properties and antioxidant activity of virgin coconut oil(2014-12) Agarwal, R.K.; Bosco, S.J.D.The present study was to investigate the physiochemical and antioxidant properties of virgin coconut oil (VCO) through different extraction processes including aqueous extraction (AE), aqueous enzymatic extraction (AEE), cold extraction (CE), hotplate heating process (HPH) and microwave extraction (MOH). Physiochemical properties of all the extracted oils were observed to be within the range of Asian and Pacific Coconut Community (APCC) standards with lower iodine, peroxide and free fatty acid values in AE, AEE and CE than those observed in MOH and HPH methods with reference to commercial VCO. However, total phenolic content ranged from 26.4 to 42.1 mg GAE 100 g-1 of oil with the effect of extraction processes. As correlation analysis showed significant correlation between total phenolic content and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging activity, β-carotene bleaching activity and total antioxidant activity, oils extracted by CE, AE and AEE had the highest antioxidant activity corresponding to their highest phenolic content as compared to those of HPH and MOH with reference to commercial VCO. Hence, the present study concluded that CE, AE and AEE could extract VCO with desirable quality and highest antioxidant activity than the other methods of extraction.Item Evaluation of dryers,... and other equipments developed by CPCRI in farmers field(Central Plantation Crops Research Institute Kasaragod - 671 124,Kerala, 1989-02) Bosco, S.J.D.Item Farmer's preference for coconut varieties - A participatory analysis(2006) Sairam, C.V.; Arulraj, S.; Thamban, C.; Samsudeen, K.; Bosco, S.J.D.; Rajagopal, V.; Arunachalam, V.Item Harvest and post harvest technology of plantation crops(CPCRI, 1998-08) Bosco, S.J.D.; Sairam, C.V.; Muralidharan, K.; Amarnath, C.H.
