Natural rubber latex can be processed into different forms through many technologies such as centrifugation, creaming, and sheeting. Sheeting of rubber latex involve collection of field latex, filtration, dilution of the field latex to a workable Dry Rubber Content, coagulation of the latex using formic or acetic acid as coagulant, sheeting into sheets and drying in open air under sun or Smoke House. A prototype Drying cabinet was locally fabricated from metal sheet grade GN8 - EN which has oven insulator, smoking chamber, insulated wall, and smoke separator base as components. It was insulated to prevent excessive heat loss to the surrounding. The outside temperatures of the system remain constant for up to an hour before experiencing infinitesimal drop during evaluation. The performance graph also shown that, the temperature increases linearly but gently along the slope. This result implies that, the system has a greater efficiency for smoking rubber sheet. Finally, the sheet produced were defects free up to 90% at a reduced production cost and drying time.
