The aim of this degree project is to apply a thermal insulator composed of abaca fibres to a macadamia nut drying oven heated by LPG from the Negoinco company in the city of La Concordia. After some research and applications of drying nuts, in different companies and workshops that are dedicated to the design and manufacture of drying ovens for cocoa, coffee and nuts of different species, it was decided to build a prototype oven, for tuning purposes practices were carried out with 3.64 kg with 40%, 80% and 100% capacity on the walls. The regulation of the gas output is done with the knob of the burner to open or close the LPG flow, for this process not much gas output is needed because the oven only has to reach a maximum temperature of 77°C. The best time was achieved with 100% insulation capacity in the oven using 3.68kg of abaca with a consumption of 0.06 kg of LPG in 38 minutes.
