New curing system for fuel, electricity and labour savings in Thailand
TransContinental Leaf Tobacco Company, Chiang Mai - Thailand
Compare physical and chemical characteristics of flavour and Thai filler styles of leaf with a brief outline of climate. Appropriate tables and graphs. Continuous flow cascade system adapted to suit requirements of curing very thin filler styles of fcv. Continuous flow chosen for its proven fuel electricity and labour saving. Drawings indicating energy saving areas. Overhead projection. Adaptations for filler styles include: 1) Heat exchange and air flow /kg leaf increased for rapid drying. 2) Wilting bay/buying bay for initial sorting of green leaf (bought by weight and ripeness from outgrowers) to ensure leaf of similar stages of ripeness are fed into Cascade. 3) Bulk curers off same boiler to take leaf not suitable for or overflow from Cascade. 4) Suitability of leaf holders to outgrower system. 5) Conditioning bay in grading shed saves down time of heating equipment as dry tobacco may be moved on trollies. Brief overview of functioning and management of system. Presented in table form will be results achieved and comparisons between old barns, traditional bulk curers and the Thai Cascade system of the following; Packing rates, heat exchange surface areas, boiler capacities, fan outputs, wet-dry leaf yields, seasonal productivity of fuel labour and electricity. Time permitting slides of key aspects of the system.
