Abstract

Thesis project Design and development of hot air oven for pig skin by bio oven Mass. Objectives to design and develop a pork skin dryer to reduce the time in the process of baking pork skin and use The most useful natural energy is drying products using the energy of biomass fuel. The dryer is divided into 2 parts: Heating and baking chambers All materials used inside the device are stainless steel. The system of the machine is to use a biomass furnace as a heat source by burning stainless steel sheets in the furnace and a blower fan using an electric motor as a power source to suck hot air into the oven through the leather. all 6 pigs layer to expel moisture in the product through the other end of the chimney. The baking temperature was 40, 50 and 60 degrees Celsius, the weight before baking was 10, 20 and 30 kg, with dependent variables.including the time spent baking and percentage of weight loss of pork skin after baking and the control variables in baking pig skin were The final relative humidity was 26%. Then, the analysis was performed to determine the baking efficiency and the physical results from the experimental results after the construction of the machine were found. increased resulting in increased baking time.The weight loss percentage of pork skin after baking decreased and as the baking temperature increased, the baking time decreased and the weight loss percentage of the pork skin after baking increased. Therefore, the weight of pigskin used in baking and the temperature used in baking were inversely proportional.The 30 kg pork skin was baked at 40 °C for 390 minutes, resulting in the lowest percentage loss of weight of pork skin after baking as 53.9.
