Dimensions are in mmFigure 8.2: Dimensional details of the solar collectorGasifier StoveThe design of the gasifier stove was adapted from the gasifier stoves developed atthe Asian Institute of Technology. Details of this stove are given in Package 2. Itconsumes about 2 kg of coconut shell or wood charcoal per hour and is capable ofproviding drying temperatures up to 60°C. Performance tests showed that a batch of50 kg of sliced pineapple with an initial moisture content of 85% (wet basis) could bedried to a final moisture content of 20% in about 18 hours at a drying temperature of60°C. The total cost of the complete drying system (including the solar collector andgasifier stove) was about US$1,120 as of Feb 2002.46
Package 9: Rice husk-fuelled Cabinet Dryer – FD200IAE/UPLB developed the FD-200 cabinet type biomass dryer, which uses rice huskas the fuel. This dryer was demonstrated in a medium-scale fruit processingcompany, which required a fairly large drying capacity. The dryer has the capacityto accommodate 200 kg of sliced fruits.Figure 9.1: The rice husk-fuelled cabinet dryer FD-200Design detailsThe dryer consists of a drying chamber and a biomass furnace-heat exchanger unit.The biomass furnace uses ricehusk as fuel, which is fed to the furnace by anautomatic feeder arrangement. An air distribution system distributes hot air evenlyto the several trays inside the drying chamber. The technical specifications of thedryer are given in Table 9.1. The design of the dryer is illustrated in Figure 9.2.Table 9.1: Technical specifications of the cabinet dryer FD200Sl. No. Parameter Specification1. Drying capacity per batch 200 kg (sliced mango)2. Average drying air temperature 53°C3. Airflow rate 0.37 m 3 /hr4. Dryer Dimensions 2.90 x 1.37 x 2.00 m5. No. of trays 52 of 0.98×0.97 m size6. Total tray area 48.4 m 27.
